be directly proportional to例句翻译_写作句库

be directly proportional to

1.be directly [inversely, reciprocally] proportional to

2.When the signal is very strong, the photon noise predominates, signal to noise ratio is not directly proportional to signal level, and care must be exercised in deriving NEP and D * from signal to noise ratio.

当信号很强时 ,光子噪声占主导地位 ,信噪比 (SNR)与信号水平不成正比 ,此时由信噪比导出噪声等效功率 (NEP)和D 时应格外小心。收藏指正

3.When maxi-mun propellant efficiency is obtained, the escaping propellant flow rate through the extraction system is independent of the input propellant flow rate, but directly proportional to the effective transmissivity of extraction system to neutral atoms and the envelope area to volume ratio of the primary electron region. Consequently, an equiform formula of maximum propellant efficiency is obtained, which can be used to predict the maximum propellant efficiency for changed flow rate and geometry.

在最大推进剂效率时,从引出系统逃逸的推进剂流量与输入的推进剂流量无关,与引出系统对中性原子的有效透明度和原初电子区的包络面积体积比成正比,进而得到了最大推进剂效率的相似公式,可用于预示输入流量和几何尺寸改变后的最大推进剂效率。收藏指正
