例句與造句

1. With the use of finite method we have developed computer simulation software for vacuum microtriodes with wedge - shaped and cone - shaped cathode on the basis of stduying deeply the field emission theory of vacuum microelectronics . the software included field section , grid point numbering , and the calculation of electric currents , transconductance and cathode capacitance , moreover , it can simulate the properties of vacuum microeletronic with variant structures and sizes . the relationship was studied and simulated among electic properties and device structures , sizes and cathode materials etc . the optimized design of vacuum microtiode was proposed
   本文在深入研究真空微電子器件場(chǎng)致發(fā)射理論的基礎(chǔ)上，根據(jù)圓錐形、楔形陰極真空微電子三極管的不同特點(diǎn)，分別建立了物理和數(shù)學(xué)模型，在考慮空間電荷密度影響的前提下，以有限元法為基礎(chǔ)采用迭代的方法計(jì)算出真空微電子三極管內(nèi)的電勢(shì)分布情況，繪制出了等勢(shì)線、電子軌跡線，并得到了器件電學(xué)性能隨幾何參數(shù)的變化情況。
2. It's difficult to find cathode capacitance in a sentence. 用cathode capacitance造句挺難的
