These two kinds of deformation data should be based on the ball three-axis test to be average. In each case the difference between any two data can not be larger than 0.03 inches (0.076 cm).

If at an altitude of 4000 feet (1219 meters) high to compete, we need to adopt the other two special balls. The first is a high degree of inter jumping to between 48 inches (121.92 centimeters) and 53 inches (134.62 centimeters), the also to make the ball's internal pressure is greater than the external pressure, the other side is identical with the above description, this ball often referred to as pressurized ball; the second addition to bouncing the ball high to 53 inches (134.62 centimeters) and 58 inches (147.32 centimeters) between, but also to make the ball pressure is approximately equal to the external pressure, and can be the altitude specified venues to keep more than 60 days, the other side is identical with the above description, this ball is often referred to as zero-pressure ball or non-pressure the ball.

Pitch types

[editOf this paragraph]

can be divided into outdoor and indoor tennis courts, golf course and there is a variety of surfaces. Their will be determined by economic factors. For example, lawn tennis is the most basic outdoor venue, but its establishment and maintenance costs are too expensive, so now replaced by the artificial pitch, it is cheaper easier to maintain. There is another popular clay courts in Europe, the French Open, this golf course shall be.

Grass field grass pitch is the oldest and most traditional means of a venue. Characterized by the ball on the ground floor with friction is small, the ball rebound speed of the player's reaction, sensitive, running speed and skills required is very high. Therefore, the grass is often seen as "offensive tennis" in the world, serving the Internet, with the ball the Internet and other online storm tactics almost be regarded as a magic weapon for winning on the grass tennis court, the bottom line-type player in the grass tennis court and difficult accomplished. However, due to the nature of grass pitches on the grass, a very high specification, combined with climatic constraints and the costly maintenance and maintenance costs could hardly be extended to around the world. At present the annual professional tennis tournament only a handful of grass are almost always held in England three islands, and the time to focus on six or seven months, Wimbledon Championships is one of the oldest and most prestigious one.

Clay

more accurate to say that "soft pitch", which is the most typical representative of the French Open on clay sites. In addition, the common variety of sand, mud, etc. can be called soft sites. Such ball landing site is characterized by greater friction with the ground, the ball is slower, the players in the running, especially in the emergency stop emergency there would be a great sliding back room, which determines the player must possess than in the other venues on a better physical fitness, running, and mobility, as well as the quality will be more stubborn. In such a venue on the race for the bottom line players locked in a stalemate is a great test of skill, players usually have to pay several times the sweat and patience in the bottom-line deal with their rivals, winning more often than not play aggressive serve Internet-based players, while the The bottom line is the hard side.

Modern hard most of the game field are hard on the tennis court, and it is the most common, the most common type of venue. Hard tennis court generally made of concrete and asphalt pave the way, its painted in red, green plastic surface layer, its surface smooth, high hardness, the ball bouncing is very regular, but the ball rebounded rapidly. A lot of good tennis players that hard tennis more "explosive" and hard court tennis tournament in dominant position, to be more respected. It must be noted that the hard texture of the site as other good elasticity, surface reaction of strong and stiff, so easy to cause injury to the players, and this damage has made a lot of good tennis players have paid a very high price.

Carpet market

the name suggests, this is a "portable" can roll up the tennis court, and its surface is a plastic surface layer, the surface layer of nylon weave, usually with a special glue adhesive on a certain intensity and hardness of asphalt, concrete the concrete substrate can be ground, and some can even be rolled or bonded directly at any supportive of the ground, its volume shop convenient, suitable for transportation and there is very strong adaptability, indoor and outdoor and even the roof can be used. Subject to site the speed of the ball surface roughness and the carpet surface roughness determined. During the maintenance on this site is very simple, as long as keeping the floor clean, not damaged, no water (for matching with the corresponding drainage facilities) on it.
