- Determination of the bore maxi-pressure point is an important link in solution of internal ballistics zero dimension model. 最大膛压点的确定是内弹道零维模型求解的一个重要环节,传统的优选方法存在着可能陷入局部极值点的问题。
- Zero dimensional and one dimensional semiconducting nanostructures 零维和一维半导体纳米结构
- Due to the probability of carrier in zero dimension being smaller than that in three dimension, the dephasing time in Ge quantum dots is lightly longer than that in bulk Si. 3. 由于载流子在零维空间受到的散射几率比三维空间小,故Ge量子点的退相时间比Si的带间跃迁的退相时间要长一些。
- This paper treats a pipe as a beam or as a thin shell. Then, the effect of cracks on the dynamic characteristics of pipes is calculated by means of the model of zero dimension element with crack. 在考虑管道长度特征的前提下,把管道近似地看作长梁或薄壳,然后以“含裂纹零维度单元”模型(即垂直于裂纹面方向的单元尺度为零)计算出裂纹对管道动态特性的影响。
