The nature of the acceleration unit-impulse response function of unbounded medium tending to vary linearly is proved by means of asymptotic analysis. Thus, the acceleration unit-impulse response function can be regarded as the summation of a linear function and a residual part which converges to zero. Based on this decomposition, two FE-SBFE coupling procedures are presented based on system realization and truncation integral technique respectively.

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。

5 Those hours that with gentle work did frame The lovely gaze where every eye doth dwell Will play the tyrants to the very same, And that unfair which fairly doth excel: For never-resting time leads summer on To hideous winter and confounds him there, Sap checked with frost and lusty leaves quite gone, Beauty o'er-snowed and bareness every where: Then were not summer's distillation left A liquid prisoner pent in walls of glass, Beauty's effect with beauty were bereft, Nor it nor no remembrance what it was.

The rationals of anti-angiogenesis are the following: the therapeutic target is tumor endothelial cells which are more genetically stable, more homogeneous, and with lower mutation rate; the anti-angiogenesis drugs can contact endothelial cells directly, with higher potency and lower drug barriers and side effects; the aim of anti-angiogenesis therapy is to block the oxygen and nutrition supply from vessels, instead of killing tumor r ells per se; the aim of anti-angiogenesis is to reduce tumor size instead of eradicate tumor which are different from traditional chemotherapy.

With this method, the nextto-leading order Debye screening mass was evaluated within real time hot QCD. Since the gluon damping rate was included self-consistently on the internal line of the self-energy, the infrared divergences were removed without putting by hand in a nonperturbative magnetic mass as a cutoff, and the results are positive and gauge-independent. In addition, the selfconsistent calculation method of the damping rates of the fast moving particles in a QGP was suggested, the self-consitent equations were derived at finite tempeature without infrared divergences, and the approximation solutions were shown. Meanwhile the relaxation times of the gluons and quarks were estimated as τ〓~0.7fm/c and τ〓~1.5fm/c at energy scales of RHIC and LHC.
