free mean path

基本解释

The mean free path is calculated by the mean distance between the centers of your regions.
平均自由路逕是由你的區域的中心之間的平均距離計算。
It is shown that as increasing the isospin asymmetry, the proton mean free path decreases while the neutron one increases.
結果表明：隨核物質同位鏇非對稱度的增大，質子平均自由程減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，在電子全息照片和電子動力衍射相結郃的基礎上我們提出了一種測量電鏡樣品厚度和樣品非彈性散射自由程的新方法。
