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。

Variable bit-rate allows a codec to change its bit-rate dynamically to adapt to the "difficulty" of the audio being encoded. In the example of Speex, sounds like vowels and high-energy transients require a higher bit-rate to achieve good quality, while fricatives e.g.
变比牲率允许编解码器动态调整比特率以适应的音频解码的&难度&,拿Speex来说,像元音和瞬间高音则需较高比特率来达到最佳效果,而摩擦音则用较少的比特即可完成编码。

In fact, situation with a zero LCL is not uncommon. In this article we propose the g-type chart with asymmetric control limits. It is found that with the nonzero LCL, the power to detect rate increase hasmuch improved and the power to detect rate is nearly fixed, and the in-control average run length is the almost the same as the symmetric control chart.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
