查询词典 freeze up

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。

TEXT: One response strategy has been to use dispersants or anti-freeze-like chemicals to break the oil up into smaller globules.

文字：一个反应策略是利用分散剂或抗冻结样的化学物质分解成更小的球油了。

Flowers and plants that work well include violas and pansies that will actually hold up if you happen to get one last freeze.

这项工作也包括花卉、pansiesviolas，其实如果您也得稳住最后冻结。

Unlike frogs that metamorphose from tadpoles into adults within a one-year period , mountain yellow-legged frogs of the Sierra Nevada take three to four years to reach adulthood, thus restricted to deeper bodies of water that do not dry up in summer or freeze solid in winter.

显然，这里 restricted 不是后置定语，不可能去修饰 adulthood ，但即使作为伴随状语逻辑意思也错误，谓语动词 take 与 restrict 这两个动作并不是同时发生的，而是两个动作存在因果关系，前一个动作导致了后一个动作，应该用因果关系的并列句来表达该逻辑关系。

Caught up in the lending freeze was Depfa Bank PLC, a little-known Dublin banking unit of Hypo.

目前世界冻干果品销售额达15亿美元，仅日本每年要花费1000亿日元进口冻干食品，俄罗斯每年缺口15万吨左右，冻干食品的主要消费地为日本、韩国、美国、俄罗斯和东南亚各国。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
