Intense competition between news agencies. To the end of the 1960s, they have put World News carved up market fundamentals. In order to confirm the de facto monopoly of the facts and their scope, January 17, 1870, Reuters news agency Havas and Wolff three reconciliation talks held in Paris and signed a split World News monopolistic market agreements - "Union Central alliance "(Ring Combination) protocol. In 1875, Reuters and on behalf of Havas and Wolff Agency signed with the New York Stock exchange news agency agreement, whereby it was agreed that a four Newswires World News carve up the market monopoly system finally established.

Acquisition news feed Europe via London three groups, three clubs in Europe to the United States only supplied to the news agency. Thus, the four World Press news agency monopoly market, which by virtue of their various advantages, repression and exclusion in each country where news organizations, forcing many of the news organizations that channel can only be obtained from their news. Edit this paragraph Union Central League and the reasons for the conclusion early 1850s, the three major European news agencies Havas, Reuters, Wolf Club have been some exchange stock quotes bilateral agreements. 1859 has also reached an agreement to exchange news, the same article, each with its own range for the issue of news, mutual non-aggression. However, with the ability to continuously improve agency operations, to enhance competitiveness, they are bound to be outwardly expand their sphere of influence. And even then it is these capitalist countries during the colonial expansion of these news agencies have gradually expanded their business into their colonies. In order to compete for market release news gathering,Nike Mercurial TF, expanding their sphere of influence, from the 1860s engaged in a fierce competition. Such competition and compete with Europe and the United States to adapt to the colonial imperialism. While in the pursuit of national interests will inevitably political, economic and other aspects of competition and conflict also reacts to the news career.

This situation is maintained until after the end of the First World War. With the rise in the United States international status and economic power, the continuous development of science and technology, the U.S. communications industry has also been great progress. 1907 United Press International's birth, influenced this World Press news agency monopoly. This new agency is not constrained joint alliance agreement, they erected own efforts in Latin America, the Far East and Europe Development. 1909, Hirst has created an international community (International News Service), the agency and the Associated Press as the Havas agency, Reuters, Wolf House, the Associated Press to enter the sphere of influence. In this situation, the AP only opt out of Union Central League.

In 1934, the major news agencies met in the Soviet capital of Latvia, accepted anywhere in the United States proposed that anyone can freely publish news principles, formally announced the abolition of all the past agreements, in full compliance with the principle of freedom of the press, news agencies according to their respective business development needs and strengths. Since then, the division of spheres of influence by the four news agencies news and information monopoly situation to an end. Thus, in the field of communications, and also the same newspaper, returned to free competition era.

structural characteristics of a propulsion system two protective system performance data expand Edit this paragraph structure features a propulsion system 1 engine of the tank with a Teledyne Continental Motors AVCR-1790-1B-type 882kW (1200 hp) engine instead made AVDS-1790 engine, power increased by 60%, the main difference is the use of a variable compression ratio piston, compression ratio changes with the load, while the other components AVDS-1790 with the same engine. (2) The tank gear with Federal Republic of Germany Lenk (Renk)'s RK304 automatic transmission replaces Allison (Allision)'s CD-850 type power transmission device with torque converter lockup clutch. The actuator includes a dual differential steering system by mechanically operated clutch, and pinion steering mechanism is available in two speeds, so that each file has two turning radius, and can realize two-speed shift in situ. Composed of one engine and transmission, maintenance disassembly is very convenient. The new power unit adapted only slightly modified for the driving force behind the cabin can be arranged. 3 suspension liquid gas tank switch to the hydraulic lift by the National Corporation (National Waterlift Company) developed by the liquid-gas suspension, which uses a single piston arrangement, elastic medium is nitrogen, the floating piston separating the oil, the suspension device is mounted outside the body, the structure is compact, each road wheel set suspension, but not to lift the body or changing vehicles pose. Using liquid-gas suspension device greatly improves the vehicle's off-road ride and the road between the shooting accuracy. Road wheel travel up to 343mm, in four road average speed of up to 38km / h. Since switching to a liquid-gas suspension, wheel diameter increased induction of the original car. Second, the protection system 1. Installation wrapped body armor on the turret sides and 22mm thick lobe portion wrapped additional armor, the armor with a Brinell hardness of more than 500 high-hardness steel, the following can be protective 125mm caliber kinetic energy in the arc surface protection force is a plus. Top of the turret and the engine compartment is also wrapped in the same upper hardness armor plate, but the thickness is small, less than 30mm caliber for protection against gun shells. On both sides of the body wrapped in a sandwich side skirts, outside two layers of high hardness steel, is used between layers shoot Thai (Sital) or similar material. By installing beaded armor, greatly improving the ultra-high-speed kinetic energy to deal with M60 tanks and anti-tank rockets and anti-tank missiles hollow charge warhead capabilities.

Allusion is from there out. What happened when the Trojans phenomenon? Hard to say, because they attack the situation varied. But if your computer has the following performance, it is likely infected with the virus hackers. Sometimes the computer crashes, sometimes restart; what to do in the absence of the time, but in desperate literacy drive; system somehow to search for the floppy drive; does not run large programs, while the speed of the system slower and slower, system resources Many; using CTRL + ALT + DEL to bring up Task table and found there are multiple names the same program running, and may increase over time increased. (However, there are some programs that do not appear in the list of. Know programming friends should know that this is not difficult to do, with PVIEW95 you can see). Especially in the network connected to the Internet or a local area network, if your machine has these phenomena, it should be careful, of course, there may be some other virus in trouble. As Trojans usually requires the destruction collaborated as viruses, Trojans most terrible. Even run, nor will certainly cause harm to your machine. However, the potential harm is still there. For example, your Internet passwords may have been someone else went to your Inbox! How to prevent it again in hacking program? I have come to experience some preventive backdoor: a,adidas predator, never perform any software or programs from unknown sources, unless your computer vulnerable to the attack level to the point of belief. Caution after the first is to download antivirus software to check it again, then run to determine the sound use. Many users is too lazy to carry out these checks a few seconds before the Trojans. Ranging from the intruder deleted system files, reinstall the system; weight is no data, hard logic lock! Or else, is being deciphered Internet account, it was tragic! Two,Nike Air Force 1 Women, never believe that you will not receive junk mail and "drugs", even if the mailbox has never been seen or isp mail, sometimes you never no way to know how others know your mail address. Third, mail software, remember to friends told him to be sure to remember to check narcotics because their computers do not necessarily attack no viruses. As my computer is equipped with a virus firewall, so I'm not sure I mail out whether the virus software. Four, never because the other side is your best friend sent me to easily carry out his or software program because you're not sure whether he, like me, installed a virus firewall, maybe your friends do not know a hacker program, thought it was a good thing to share with you send it! Also, you can not guarantee that if there is someone else to take his name to send you mail. Fifth, do not just leave your personal information, because you never know whether someone would deliberately collected. Six, do not easily believe that the network met new friends, because "on the network, no one will know that you are a dog!

Trigonometric Leveling Technology definitions Chinese name: English name Trigonometric Leveling: trigonometric leveling definition: the endpoints of each side by observing zenith distance, using the known point elevation and known side length to determine the elevation of each point measurement techniques and methods. Applied science: Surveying and Mapping (a subject); Geodesy (two subjects) The above content validation by the National Science and Technology Commission approved to publish trigonometric leveling (trigonometric leveling), by observing the horizontal distance between two points and the days zenith distance (or elevation) to find definite height difference between two methods. It observational method is simple, not the terrain conditions, is the determination of the basic geodetic control point elevation method.

Basic Principles on the Calculation Method Edit this paragraph the basic principles of the basic principles of trigonometric leveling Figure, A, B two points on the ground,Adidas F50 TF, observing from point A to point B, the vertical angle α1.2 , S0 is the horizontal distance between two points, i1 point A instrument height, i2 spy for the elevation of point B, then A, B height difference between two points h1.2 = S0tga1.2 + i1-i2 above formula assumes that the Earth's surface is a plane, a straight line of sight conditions of observation derived. In geodesy, due to the side length is longer, you must take into account the curvature of the Earth and atmospheric vertical refraction differential impact. In order to improve the accuracy of trigonometric leveling, usually taken to the observation vertical angle, height difference between two points Deriving to weaken the impact of vertical atmospheric refraction.edit this section affect one hundred years ago, trigonometric leveling is the main method of measuring height. Since the emergence of standard measurement methods, it has been relegated to secondary status. However, because the job is simple,Nike Flex Experience Rn Mens, in the mountainous and hilly areas are still widely used. Zenith distance observations being seriously affected by atmospheric refraction ground. If the atmospheric density is uniform, the light emitted by the light source L will be in the form of concentric spherical wavefront propagation in all directions, the speed and density of the atmosphere to adapt. In fact, the atmospheric density generally increases with the increase of height reduced, the upward velocity of propagation of light in the horizontal direction than the large. This is no longer concentric spherical wavefront, but in the form shown in Figure 1. At this station the observation light source S L, the telescope perpendicular to the wavefront, as seen by the direction of the light source, as shown by the arrows; dotted line in the figure the path of the line of sight, it is everywhere perpendicular to the wave front. This phenomenon is called the ground atmospheric refraction, depending on the direction of the light source and the true direction of the angle between the γ SL is called refraction angle. In trigonometric leveling, angle depends on the refractive index between the target station and observed the physical conditions of the atmosphere, especially the atmospheric density lapse rate upward. Surveying in practice, it is impossible to fully grasp the physical conditions of the atmosphere to calculate the refraction angle, there is generally only estimate its value, or take appropriate measures to weaken it to the final results. Edit this paragraph calculation method triangulation measurements to calculate the height difference between two points, is based on the ellipsoid,Adidas AdiPure FG, so obtained is ellipsoidal height elevation. Figure 2, A, B points of the ellipsoid height H1, respectively, and H2. First, excluding the vertical deflection omitted, set from point A to point B observed zenith distance of Z1 (or elevation angle α1 = 90 °-Z1), the two o'clock in the projection of ellipsoid arc length apart A0 and B0 as S0, A0B0 arc radius of curvature R0, then A and B height is: where is the earth curvature term impact; term effects of atmospheric refraction; k is the refraction coefficient, usually using the average k = 0.10 ~ 0.16 . The above is from point A to point B observed zenith distance Z1 (or height angle α 1), to find definite height difference between the two situations is called unidirectional trigonometric leveling. If A, B two points each observation zenith distance Z1 and Z2 (or height angle α 1 and α 2), set the required height difference between two points is called on to trigonometric leveling. Used for observation due to trigonometric leveling is carried out under the same conditions, two opposite directions refraction coefficient k can be considered approximately the same, and therefore do not have to consider the refraction correction items. Especially at the same time to be right when observed ellipsoidal height h of the equation simplifies to:. On the trigonometric leveling, assume the opposite direction of the refraction coefficient of the same, of course, may not be entirely realistic, but more than one way to apply trigonometric leveling much more reliable valuation of k. Therefore, generally used for the trigonometric leveling. Elevation above formula, not taking into account the vertical deviation of the station zenith distance to the observer effect. In flat areas used for the trigonometric leveling, this effect is small. In addition, the formula is derived from a process point of view, the determined height is ellipsoidal height, to be counted as being of high or normal system height, must join corrected. In the triangular mesh or wire network, can be determined by the trigonometric leveling ellipsoid height difference between two points, if more of these points obtained by the leveling for geoid height can be obtained at each point geoid For ellipsoid gap. Therefore, from a theoretical point of view, trigonometric leveling is also a means of measuring the shape of the earth, it does not depend on any assumptions. But because people generally can not be measured with sufficient accuracy refraction coefficient, trigonometric leveling so far only for the determination of low-precision elevation. Improve Trigonometric Leveling measures are four: 1, shortened attention. When the length of 1000 meters line of sight, the refraction angle and usually only 2 "or 3." In such a distance on the right to trigonometric leveling, the accuracy with ordinary leveling fairly. 2, the observed vertical angle. 3, choose a favorable observation time. Under normal circumstances, the vertical angle observations around noon most favorable. 4, to improve eye level.
