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.
Space probe according to the detection of object is divided into lunar probe, probe and interplanetary spacecraft, small body such as a space probe to leave the speed of the earth must be large enough to overcome or get rid of the earth's gravity, realize the deep space flight. The probe orbits the heliocentric elliptical orbit (double-cut orbit) that is tangent to the earth's orbit and the planet's orbit, and may meet the target planet; Increase speed to change the orbit, flew to target the planet can shorten the time in order to ensure the detector fly the double track to the planetary orbits and tangent with the target when the target planets also run to it, must be chosen in the earth and the target planet at a particular moment of relative position detector. Detector can fly around the star, the use of planetary gravitational fields accelerate continuous multiple planets orbit the significant characteristic of space probe is, flying in space for long time, the ground cannot real-time remote control, so must have the ability of autonomous navigation; To fly outside the solar system, away from the sun, solar arrays, and nuclear energy systems; It is necessary to adopt special protective structure to withstand very severe space environment. Landing or walking on the surface of the moon or planet requires some special form of structure
Also known as the sleeper plate circuit. It is a prestressed concrete sleeper plate, which is laid in a compacted bed, and the wires are filled with asphalt or other materials. The prestressed concrete sleeper plate is 55cm wide and twice as wide as the normal prestressed concrete sleeper, with the same length and thickness as the ordinary prestressed concrete sleeper (see color map). Therefore, the contact area between the wide sleeper and the daoist bed doubles the contact area between the normal sleeper and the daoist bed, thus reducing the pressure on the bed
