查询词典 electrons

The transit time and gain characteristics of electrons which travel in the micro-channel plate gated by picoseconds high voltage pulse were simulated.

CO 5σ中C原子的杂化形式也由sp杂化转化为sp~2杂化。K的共吸附使CO各轨道的电离势有所上升。

The intensity of NP peak of type-Ⅱ initailly increased with the increase of the excitation power and decreased thereafter. This is due to the electrons and the holes were localized in different space of typ-Ⅱ QW, then the band bending occurs when the carrier concentration increases with the power, NP peak shft to high energy. The electron transited to relaxed Si〓Ge〓 layer and combined with the localized holes radiatively.

型量子阱的NP峰随激发功率增加先增加后减小，这是由于在Ⅱ型量子阱中电子和空穴不在空间同一位置，较强激发功率下产生的高浓度载流子引起能带弯曲严重，NP峰向高能方向移动，到某一定程度时开始出现电子跃迁至弛豫Si〓Ge〓层与其中的空穴复合发光。

When the device was at forward bias, the holes in the p-type silicon tunneled into the defect states in ZnO:Al and then radiatively recombined with the electrons in ZnO:Al film, thus yielding an electroluminescence spectra at the wavelength at 590nm.

另一方面，当元件操作在顺向偏压时，由於ZnO：Al薄膜内的缺陷提供了p-Si内的电洞利用穿隧效应进入ZnO：Al薄膜的途径，这些电洞进而与ZnO：Al导电带的电子结合而发光，因此我们量测到波长在590nm的可见光发光频谱。

MPI may result in a sharp rise of threshold fluence Fth on \tau, and AI may lead to a mild increase or even a constant value of Fth on \tau. MPI serves the production of seed electrons for AI when the electron density for AI is approached or exceeded before the end of MPI.

MPI结束之前所离化的电子密度如果达到或者超过AI电子密度，则意味着MPI是产生种子电子的主要渠道，此时初始电子密度的影响可以忽略。

The charge distribution result shows that the carbon is easy to get electron, and the nitrogen with lone pair electrons in the amino group is the electrophilic reaction site.

电荷分布方面，三聚氰胺分子上的碳原子易得电子为亲核试剂进攻点，而胺基上的氮原子因含孤对电子是亲电反应中心。

Transmitted electrons were finally detected by a channeltron electron multiplier operating in single-pulse mode instead of usual measuring current intensity, which can reduce the acceptance solid angle and the contribution of elastic scattering in the forward direction can be minimized effectively.

因采用了恒温控制作用室，以便较准确测量反应室的绝对气压值；同时采用静电型圆柱能量分析器，并用计数率测量模式代替通常的束流强度测量模式，从而可以大幅度减小接收立体角，抑制零度角的弹性散射贡献。

Waves propagating with the electrons rotate their wave vectors downwards in the upper electrojet and upward in the lower electrojet.

这是由于波的群速度方向是向下的，而电子密度梯度起稳定化作用。对于电子密度的特征长度L_N=6km和│E_D│=0.8mV/m，波长λ=10m，高度h≥105km，有r0。

A Monte Carlo model was used to simulate the spatial and energy distribution of the emission electrons from the micro hollow cathode discharge, based on these results, spatial distribution of the electron in the micro hollow cathode sustained glow discharge was also modeled.
