spherical shell

基本解释

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。

This book, which describes the descendants of a civilisation that has converted the material in its planets into a giant ringlike structure around its sun, was inspired by Freeman Dyson's idea that a truly technologically advanced species would endeavour to capture as much light as possible by building a spherical shell around its central star.
ECONOMIST: Is it time for a new approach to finding extraterrestrials?

球殼
The type of load have great influence on limit load and this influence mainly lead by the effect on radial moment mr . And the limit load of shallow-spherical shell decrease with c~2 increases, while increases whenαdecrease.
不同荷載類型對扁球殼的極限荷載有較大影響,這種影響主要躰現在對逕曏彎矩mr的影響上;扁球殼的極限荷載隨著幾何特征值c~2的增大而減小,隨著拉壓屈服極限比α的減小而增大。
