双语例句
- In order to ensure the safety in operation of orbital spacecrafts, especially the long duration and large size spacecrafts. Space debris and meteoroid shield are very important factors in the designing of spacecrafts.
为了保证在轨航天器的安全运行，微流星体和空间碎片的防护成为现有航天器，特别是长寿命、大尺寸航天器设计时必须考虑的因素。 - Most of the spacecrafts are suffering from the bad space environment, and the space debris, included meteoroid and orbital debris, imperiled the spacecrafts most.
其中对航天器威胁最大的就是空间碎片，包括微流星体和轨道碎片。 - When a meteoroid enters the atmosphere, it compresses the air in front of it.
当流星体进入大气层，它压缩的空气在前面的。 - Studies on meteoroid streams are briefly and systematically presented.
对流星群的研究作了简明而系统的介绍。 - So far many countries are researching the technology of risk assessment of space debris impact, some of them already have a risk code, which can be used to value the risk assessment for the spacecraft in both meteoroid and orbital debris environment.
目前各航天大国都在研究航天器风险评估技术，有些国家已经有了成熟的风险评估软件，可针对微流星体环境和轨道碎片环境分别对航天器进行风险评估。 - Risk Analysis of Meteoroid and Space Debris High-velocity Impact on Spacecraft
微流星及空间碎片高速撞击航天器风险度分析 - And even smaller type of interplanetary debris is the meteoroid.
甚至更小的太阳系内的碎片也是流星体。 - The probability of impact or failure is calculated by Finite Element Analysis Method and the arithmetic flow of spacecraft risk assessment in the meteoroid environment is designed. Second, both the earth shadowing effect and the spacecraft shadowing effect are discussed thoroughly.
