Germany is the world's first international auto show. The Frankfurt motor show, formerly known as the Berlin motor show, was founded in 1897 and moved to Frankfurt in 1951, with a rotation of cars and commercial vehicles each year. The Frankfurt motor show is the world's largest auto show and is known as the "motor Olympics". The Frankfurt international motor show, which is held every two years, is normally scheduled for about two weeks in mid-september. The exhibitors are mainly from Europe, the United States and Japan, especially European auto dealers. Frankfurt is in Germany and the main character is German business, which seems to be the same as the regional nature of the Detroit auto show and the Tokyo motor show. Germany is the birthplace of hyundai motor, the home of mercedes-benz, Volkswagen and audi, and the Frankfurt motor show is a great opportunity for them to strut their stuff
Peugeot began its reign in motorsports since the start with the entering five cars for your Paris-Rouen Trials in 1894. These motorsport trials are largely thought to be the 1st motor sports competition. It was not until 1912 that Peugeot made its perhaps most obviously contribution to motor sports when one of several entered cars won the French Grand Prix. This winning Peugeot car was advanced and influential for later designs since the Peugeot featured a dual overhead cam configuration with four valves per cylinder. The Peugeot innovation made it in a way that the engines could possibly be smaller and kick out maximum horsepower versus depending upon larger heavier engines to obtain the desired horsepower.
However, science and technology are two different social cultures, and the differences between them are obvious. The basic task of science is to know the world and find it, thus increasing the intellectual wealth of mankind. The basic task of technology is to discover the world and invent it to create the material wealth of mankind and enrich the spiritual and cultural life of human society. Science answers questions about "what" and "why"; The technology answers the question "what to do" and "how to do". Therefore, the results of science and technology are different in form. Scientific achievements are generally expressed as concepts, laws, papers and other forms. The technical results are usually in the form of process flow, design drawing, operation method and so on. Scientific products are generally not commercial and technological achievements can be commoditized. Modern technology has a strong utilitarian and commercial color.
Spacecraft flew hundreds of thousands to hundreds of millions of kilometers from the earth, injecting speed when the size and direction of a slight error, arrived at target planets will appear large deviation error, for example, when Mars probe injecting speed 1 m/s speed (about one over ten thousand), arrived at Mars, about 100000 km distance deviation. Therefore, precise control and navigation must be carried out during the long flight. Flying to the moon is usually controlled by the orbital control system of the ground and space probe (see orbit control). Interplanetary flight distances, radio signal transmission time is long, the real-time remote control, can't so planets and interplanetary spacecraft orbit control system shall have the ability of autonomous navigation (see interstellar travel navigation and control). The United States, for example, "pirates" spacecraft in space flight of more than eight hundred million km, for 11 months of 2000 times of autonomous orbit adjustment, the final surface to achieve a soft landing on Mars, placement accuracy up to 50 km. In addition, in order to ensure the accuracy of the orbit control engine, the communication antenna is always aimed at the earth, and other systems work normally, and the detector has the autonomous attitude control ability
