shell thickness

基本解释

The initial velocity of ceramic balls could be controlled by appropriately adjusting the shell thickness.
可适当调节壳体壁厚来控制陶瓷球的初速。
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.
通过实验，研究了拉坯速度和结晶器冷却水量对铸坯在结晶器出口处坯壳厚度的影响。
Average heat flux does not reflect local flux entirely, and high heat flow region can reflect shell thickness in time.
平均热流不能完全反映局部热流的变化，局部热流能更及时地反映坯壳的凝固情况。

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.
在某个位置为,厚度为dr的壳层内,找到原子,的概率，我们来考虑下我们这里所说的。

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.
在某个地方的完美球型壳层,厚度，我们把它叫做4πr平方，我们仅仅是把它,乘以概率密度。
