| A new kind of radar has been developed
for spaceship travelers. A working laboratory model of a new system of radar
that makes use of a beam of light is said to be ten thousand times more accurate
than the best comparable system of radar that used microwaves. The model has shown that this radar system, known as laser-doppler radar, can measure with absolute precision speeds varying from spaceship orbital injection (进入) velocities (速度) of five miles per second down to virtual stops—speeds of less than one ten thousandth of an inch per second. According to the scientists who are developing this system, such fine measures of velocity are of prime importance in space missions. In a rendezvous (对接) between two spaceships, or in a landing approach by a vehicle onto an orbiting space station, a bump could rip open a ship’s skin, or a A. laser-doppler radar is more accurate than microwave radar B. microwave radar may not ensure absolute precision in measuring varying speeds C. the light-beam radar can measure only slow speeds with accuracy D. microwave radar operates at a higher frequency than laser-doppler radar [单选题]试验制动机减压时,口笛、号角明示方式为( )。

Hall’s 1966 proxemics, is the region surrounding each person, or that area which a person considers his domain or territory. Often if entered by another being without this being desired, it makes them feel uncomfortable. The amount of space a being (person, plant, animal) needs falls into two categories, individuate individual physical space (determined by imagined boundaries), and the space au individual considers theirs to live in (often called habitat).
What distance is appropriate for a particular social situation depends on culture. It is also a matter of personal preference. Personal space is highly variable. Those who live in a densely populated environment tend to have smaller personal space requirements. Thus a resident of India may have a smaller personal space than someone who is home on the Mongolian steppe, both in regard to home and individual. Personal space can be determined on a habitat level by profession, livelih A. Personal space means the space one occupies as a resident. B. The research of personal space originated from promexics.
