ab sub-mother lineThe "A B" string was a type of string used in the racket. It was usually referred to as the AEROBITE string of YONEX, or BG-A B. The mother and son lines were different in the horizontal and vertical lines, and the vertical lines were generally thicker. The advantages of the A and B line were that it had good elasticity, a feeling of killing the ball, a nice sound when hitting the ball, and the ball sticking to the net. The disadvantage of the A/B line was that it was more expensive. It was easy to break when it was cold and dry in winter or when the temperature difference was large. It was one of the more expensive lines. The special feature of the A and B wire was that the horizontal wire used was a ball wire with a diameter of 0.61mm. It had very good elasticity, but its durability was average. The A and B lines were suitable for players who pursued high bounce and ball control, as well as for players who were both offensive and defensive. There were two ways to thread the A and B thread, and four ways to tie them. The difference was that the four ways would cut the thread and pull it horizontally and vertically. The weight of the two-knot would be more sufficient, the weight loss would be slower, and the outer frame would be more concise, while the net pressure of the four-knot would be more balanced, and it would be suitable for the Yonex quality assurance. It was important to note that only four knots were pulled on the A and B wire. In general, the A-B string was a kind of racket string with good elasticity and ball control performance. It was suitable for players who pursued high elasticity and ball control.

Wernher von BraunBorn on March 23, 1912, in Wilschitz, Germany, he died on June 16, 1977. He was the pioneer and founder of liquid fuel rocket technology and aerospace engineering in the 20th century.
He was obsessed with space exploration after receiving a telescope from his parents on his 13th birthday. He did not perform well in physics and mathematics in his early years, but he achieved excellent results after being inspired by a related book. He had conducted dangerous chemistry and rocket experiments, which led to the establishment of the Space Travel Association (VfR) on July 5, 1927, and he was very enthusiastic about the journal Die RaketeI published by the association.
At the end of 1930, the abandoned ammunition depot rented by the British Defence Force became the Rocket Experiment Center (Raketenflugplatz). At this time, he performed well in university engineering and mathematics and became a regular writer. In April 1932, a representative of the German Army Ornaments Ballistic and Ammunitions Department visited the site to lay the foundation for his role in the development of the V - 2. The Ornaments Department arranged research funding for him. He conducted research at the Nazi-Kurmersdorff test site, during which he designed some models of the Aggregat liquid fuel rocket series. After that, they moved to the new base in Penemunde.
At the age of 25, he entered the Penemunde Rocket Research and Test Center as the director of the technical department in charge of rocket research. On October 3, 1942, the V-2 rocket, which was improved on the basis of the "A" series of rockets developed by him, was successfully tested. After 1945, he joined the American camp and became an American citizen in 1955. He served as the Director of the Development Division of the US Army Missile Bureau and developed the Redstone, Cupid, and Pershing missiles. On January 31, 1958, the "Cupid C" launch vehicle designed by him was used to send the first artificial Earth satellite, Explorer 1, into orbit. In the 1960s, he was appointed as the space science advisor to the president of the United States, in charge of the Apollo moon landing project and directly presided over the development of the Saturn 5 launch vehicle.
