velocity focusing

常見例句

One difficulty with direct methods is that the designer spends a great deal of time focusing on the velocity distribution; the geometry is secondary.
一個(gè)直接的方法就是難度設(shè)計(jì)者花費(fèi)大量的時(shí)間專注於速度分佈；幾何爲(wèi)輔。
Such as how to select focus functions and focus windows, how to perform feedback control, and how to improve the auto-focusing velocity etc. , are far from completely solved.
在如何選擇對焦評價(jià)函數(shù)和對焦區(qū)域、如何進(jìn)行反餽控制和如何提高對焦速度等方麪，還有諸多問題有待解決。
The results showed that the effect of group velocity dispersion(GVD) on the pulse with large chip was slight and the effect of spectral width on the self-focusing properties could be ignored.
研究結(jié)果表明，群速度色散（GVD）對大啁啾脈沖的影響很小，譜寬對自聚集的影響可以忽略。
