After that, According to the induced-matter idea, we study the generalizational method of 5D Dirac equation, and point out that Dirac equation isn't formally generalized in principle because the wave function of Dirac field is multiple component matrix form.

随后，我们从诱生物质思想出发，研究Dirac方程的五维推广方案，指出由于描述Dirac粒子的波函数是多分量的矩阵形式，原则上不能只依靠单纯的形式推广。

This work is sometimes said to have influenced Paul Dirac in his creation of the Dirac equation for the relativistic electron, though Dirac stated that he invented these same matrices himself independently at the time, without Pauli's influence.

泡利的主要成就是在量子力学、量子场论和基本粒子理论方面，特别是泡利不相容原理的建立和β衰变中的中微子假说等，对理论物理学的发展做出了重要贡献。1945年，泡利因他在1925年即25岁时的"发现不相容原理"，获诺贝尔物理学奖。

We study the Dirac structures on protobialgebroid, give the integrable conditions for maximally isotropic subbundle being Dirac structure for protobialgebroid by the notion of characteristic pair. From the integrable conditions, we found out that Dirac structure has closed relations with twisting of protobialgebroid. Further, the closed relations are explained, the fact that twisting of protobialgebroids is a equivalence relation is verified.

详细研究了proto双代数胚匕的Dirac结构，给出了极大迷向子丛可积的充要条件，发现在这些充要条件中蕴含了proto双代数胚的扭关系，进一步阐明了扭与Dirac结构之间的内在联系，证明了扭在proto双代数胚范围内是等价关系。

现在很多乳品企业都利用报表这种管理工具来进行营销管理，比如促销员有促销日报表，库存报表，竞品监测报表；业务员有经销商，大商超的拜访报表，出差行程表等；区域经理有出差行程表，销售月度报表等。

Up-to-date, all ET models are based on Boltzmann statistics. To extend ET model to Fermi statistics, several Fermi integrals of different orders have to be frequently calculated.

目前的ET模型都是基于Boltzmann统计的，为了把ET模型推广到Fermi统计，要求频繁地计算几个不同阶的Fermi积分，其中有半整数阶，也有一般的实数阶。

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。

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
