initial yield surface

基本解釋

The proposed model can take into account the initial anisotropy by introducing anisotropic tensor and shape parameter based on yield surface of MCC.
該模型具有以下特點(diǎn)：其一，在修正劍橋模型屈服面中引入各向異性張量和形狀參數(shù)，邊界面形狀靈活又可以反映初始各向異性的影響；
If the burst is shallow enough to penetrate the surface, blast, thermal, and initial nuclear radiation effects will be present, but will be less than for a surface burst of comparable yield.
如果離地面夠淺以致能穿透表面，那么將出現(xiàn)沖擊波、熱輻射以及早期核輻射作用，但是作用效果要小于近似當(dāng)量的地面爆炸。
