The simulation results show that the three models are all selfconsistent with electromagnetic field. Gauss law model tends to be affected by the width of the first cell and yield nonphysical oscillation. 1D diode model with reasonable discrete grid gets almost the same results as Child law model, but it needs to solve a transcendental equation, which would cost much time.

模拟结果表明，三种模型都能与电磁场自洽并反映外加磁场对发射电流的影响，但高斯定律模型受网格剖分粗细程度的影响较大且容易产生振荡，一维二极管模型在网格参数合理的情况下结果与查尔特定律模型基本接近，但需要求解超越方程，花费时间多。

When applying this model to build movement differential equation and deduce the stable oscillation angular velocity gain formula, existing literature has made many hypotheses, neglection or simplification, which have many insufficiencies.

现有文献在应用该模型建立运动微分方程并推导稳态横摆角速度增益公式做了许多假定、忽略或简化，有很多不足。

The mathematics model of oscillation driven by hydraulic pressure is founded using bond graph theory and its system state equation is detruded.

利用仿真软件MATLAB进行了仿真研究，分析了影响系统动态特性的诸多因素，给出了改进系统性能的措施。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
