The test has a wide range of test points, including politics, law, economy, humanities, geography, science and technology, life, etc., which requires long-term and uninterrupted accumulation of partners. The general knowledge-related test point brought to you today is "traffic knowledge in daily life".
1. Trains1. Train number.
There are more than 10 kinds of trains on Chinese railway train tickets, such as C, D, G, Z, T, K, etc. Trains starting with C: intercity EMU trains, pronounced as "city". On August 1, 2008, China's first intercity railway, the Beijing-Tianjin Intercity Railway, was officially put into operation, with a maximum speed of more than 350 kilometers per hour.
Trains starting with D: EMU trains, pronounced as "moving". The name of the EMU used in China is "Harmony", the English abbreviation is CRH, and the full name is China railways high-speed (China Railway High-speed). Trains starting with G: high-speed railway EMUs, pronounced "high". On December 26, 2009, China's first high-speed railway, the Wuhan-Guangzhou high-speed railway, was officially put into operation, with a design speed of 350 kilometers per hour and a maximum speed of more than 380 kilometers per hour.
Trains starting with Z: direct express passenger trains, pronounced "straight". On April 18, 2004, the national railway system increased its speed for the fifth time. Trains starting with T: Express passenger trains, pronounced as "special".
Trains starting with K: fast passenger trains, pronounced "fast". 2. Maglev train.
Maglev train is a modern high-tech rail transportation tool, which realizes non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to pull the train to run. China's first maglev train (purchased from Germany) began to operate on the Shanghai Maglev Line in January 2003.
On May 6, 2016, China's first medium and low-speed maglev commercial operation demonstration line with completely independent intellectual property rights - Changsha Maglev Express Line was opened for trial operation, which is also the world's longest medium and low-speed maglev operation line. 2. Aircraft
1. Black Box After a plane crashes, the relevant departments have to do everything possible to find the "black box" that fell from the plane. Because the black box is the most important and direct evidence to determine the cause of a flight accident.
The official name of the black box is the Flight Data Recorder. Although it is called a black box, its color is not black, but a striking orange. According to statistics, the tail under the tail of the aircraft is the safest place on the aircraft, so the "black box" is installed here.
2. The size of the wing lift depends on the relative speed of the aircraft and the air, not the relative speed of the aircraft and the ground.
When the aircraft takes off against the wind, the relative velocity with the air is equal to the speed of the aircraft taxiing plus the wind speed, because the relative air movement speed is large, the lift is also large, so that the gliding distance can be reduced, on the contrary, when taking off downwind, the lift is relatively small. When landing, if it is downwind, the relative velocity of the air is small, and the aircraft must increase its speed to overcome the effect of wind speed in order to maintain normal lift. This not only increases the distance of the taxi, but also makes it difficult for the aircraft to land accurately, and may even cause the aircraft to rush off the runway and cause an accident. Landing against the wind can effectively avoid this situation and increase safety.
