shell thickness

基本解釋

The initial velocity of ceramic balls could be controlled by appropriately adjusting the shell thickness.
可適當(dāng)調(diào)節(jié)殼體壁厚來(lái)控制陶瓷球的初速。
On the basis of experiments, research the relationship between solidified shell thickness at the end of copper mold and technology parameters such as casting speed, cooling water flow.
通過(guò)實(shí)驗(yàn)，研究了拉坯速度和結(jié)晶器冷卻水量對(duì)鑄坯在結(jié)晶器出口處坯殼厚度的影響。
Average heat flux does not reflect local flux entirely, and high heat flow region can reflect shell thickness in time.
平均熱流不能完全反映局部熱流的變化，局部熱流能更及時(shí)地反映坯殼的凝固情況。

r And what that is the probability of finding an electron in some shell where we define the thickness as d r, some distance, r, from the nucleus.
在某個(gè)位置為,厚度為dr的殼層內(nèi),找到原子,的概率，我們來(lái)考慮下我們這里所說(shuō)的。

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(gè)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。
