Finally , we can get a curve of electron density changing with the time or the position . this is the result required of system 并最终得到了系统所要求的电子密度随时间t或随位置x / d的变化曲线。
Electron density is one of basic parameters of laser - produced plasma , so it has a important role in diagnosis of laser - produced plasma 电子密度是激光等离子体最重要的基本参数之一,因此在激光等离子体诊断中占有重要位置。
In the third group , the electron density of corneal collagen fibres were uneven with dilated and low electron - densed interfibral spaces 第二组中,角膜胶原纤维排列规则、连续,电子密度均匀,纤维间可见散在扩大的空隙,呈低电子密度灶。
Then , an implicit expression for electron density and a closed form of threshold voltage are presented fully comprising quantum mechanical ( qm ) effects 给出了电子密度的隐式表达式和阈电压的显式表达式,它们都充分考虑了量子力学效应。
The analytical solutions to 1d schr ? dinger equation ( in depth direction ) in double - gate ( dg ) mosfets are derived to calculate electron density and threshold voltage 摘要推导了双栅mosfet器件在深度方向上薛定谔方程的解析解以求得电子密度和阈电压。
