free mean path

基本解释

The mean free path is calculated by the mean distance between the centers of your regions.
平均自由路径是由你的区域的中心之间的平均距离计算。
It is shown that as increasing the isospin asymmetry, the proton mean free path decreases while the neutron one increases.
结果表明：随核物质同位旋非对称度的增大，质子平均自由程减小而中子的平均自由程增大。
New methods of measurements of specimen thickness and non-elastically scattering mean free path are proposed based on the electron holograph combining with electron dynamic diffraction.
而且，在电子全息照片和电子动力衍射相结合的基础上我们提出了一种测量电镜样品厚度和样品非弹性散射自由程的新方法。
