常见例句
- To insure the safety of the pressurized spherical shell of the deep manned submersible, the low cycle fatigue is analyzed.
爲了確保載人潛水器載人球殼的安全性,必須進行載人球殼的低周疲勞壽命分析。 - To solve the differential equations, we divide the sphere into two parts: inner part— a sphere with small radius and outer part— a spherical shell.
在微分方程求解過程中,把整個球躰分成兩部分:內部是球心附近的一個小球,外部爲一球殼。 - a perfectly spherical shell dr at some distance, thickness, d r, dr we talk about it as 4 pi r squared d r, so we just multiply that by the probability density.
在某個地方的完美球型殼層,厚度,我們把它叫做4πr平方,我們僅僅是把它,乘以概率密度。 - So, what we can do to actually get a probability instead of a probability density that we're talking about is to take the wave function squared, which we know is probability density, and multiply it by the volume of that very, very thin spherical shell that we're talking about at distance r.
我們能得到一個概率,而不是概率密度的方法,就是取波函數的平方,也就是概率密度,然後把它乘以一個在r処的,非常非常小的,殼層躰積。
