查询词典 orbit

The temperature gradient occurs imperatively and then influences to the image quality and resolution of the space camera. Based on the theory of optical wavefront error and combining the engineering practice, the thermal optical evaluation has been done to the optical window with non symmetric temperature field. The RMS wavefront errors of the optical window have been calculated on each typical position in orbit cycle.

The high precision electrostatic accelerometer is one of the key payloads for Earth's gravitational satellite, and its sensitivity parameters directly determine non-conservative force measurement, and eventually influence the precision of Earth's gravitational field recovery, so that it needs to be calibrated in-orbit.

用于检测微弱信号的高精度惯性传感器，其设计过程中的一个重要环节是分析检验质量的引力场分布。

Although the stabilization fund is not directly address the question of the size of the non-symptomatic, but if used for the benefit not only the direct intervention because of the size of speculative capital and non-malicious guest at the stock market caused by the abnormal fluctuations, but also through increasing Index heavyweight buy or hold the key to the size of some of the non-speculative selling and to stabilize the stock price, or let the market back to life after all the good opportunities and will be returned to properly resolve the issue of the size of the market in order to restore the function of orbit and re - Plastic confidence in the market start.

但如果用于受益，不仅是由于投机资本的规模和非直接干预，恶意住客股市造成的异常波动，而且也通过加强权重股购买或持有的部分非大小，投机性抛盘以及稳定股票价格，或者让市场恢复在所有的生活和良好的机遇的关键将返回到妥善解决了该市场的规模问题，以恢复轨道和重新功能-塑料在市场开始的信心。
