Simultaneously, the exports of ionization rate and nonionzed concentration are set up as a powerful tool for studying thoroughly the freeze-out effect. dN〓/dp and dN〓/dn are neglected in the linearized equation system of the iteration methods of Newton and Gummel, due to having lower 15 orders or more than dN〓/dn and dN〓/dp, thus the computing effort is cut down with no effect on precision. A new cut-off technique is adopted to accelerate the convergence speed, about twice reduced for Newton iteration method and six times or so for Gummel iteration method. The approximate formulae of Fermi-Dirac statistics are also put forward with simpler form and higher precision. 3. A term dependent on time is added to the electron and hole current succession equations respectively. It is only this model that conservation of charge in transient analysis and alternating small-signal analysis at low temperature can be kept by. 4. The performance of SE-PISCES is explained by the simulation example of PISCES-2B, diode.

研究了低温半导体器件模拟的数值方法：对载流子浓度进行了新的归一化；编制了不考虑掺杂所引进的内建电场时的电离率计算程序；由于低温杂质电离率随偏压状态而变化，为此编制了每次求解迭代时的电离浓度计算程序，并将其插入到求解迭代程序中；同时，设置了杂质电离率和未电离杂质浓度的出口点，为更深入地研究冻析效应提供了有力工具；在Newton迭代法和Gummel迭代法的线性化方程组中忽略了dN〓/dp、dN〓/dn，是因为它们比dN〓/dn、dN〓/dp低15个数量级以上，这样减小了计算量又不影响模拟精度；对Newton迭代法和Gummel迭代法采取了新的截断技术，提高了收敛速度，Newton法迭代法和两次左右，Gummel法减少六次左右；给出了表达式更简单而精度更高的Fermi-Dirac积分近似计算公式。

The ideal quantum gases obey Bose-Einstein or Fermi-Dirac statistics and the flux can be derived from the known distribution function. In this sense, we develop the kinetic schemes that suitable for ideal quantum gas and investigate the influence of the quantum effect. In this thesis we discuss shock tube problems and shock diffraction by wedges and shock diffraction by cylinders for the ideal quantum gases.

理想量子气体之速度分布依循Bose-Einstein或Fermi-Dirac分布，在已知气体分布函数的情况下，对分布函数取矩可得宏观量及其通量，本文即利用此概念发展适用於理想量子气体之气体运动算则，并探讨量子效应造成之影响，本文探讨理想量子气体之震波管、楔形体和圆柱震波绕射问题。

To getrid of these shortcomings DMs are presented in quantum theorywhere the movement of individual electron is determined byquantum mechanics and the system of electrons obeys Fermi-Dirac statistics,in consequence they can find wider appli-cations than classical DMs.

这里个别电子的运动由量子力学刻画，多电子系遵循Fermi-Dirac统计规律，故它们比前三种经典公式普适性更强。
