NBTI effects can also be influenced by ratio of signal and vacancy. The dynamic characteristics in NBTI degradation was revealed under action of negative and positive gate voltage, degradation can be recovered by positive gate voltage stress.

在负-正-负栅压交替作用下PMOSFET器件中会呈现退化-钝化-退化的动态作用过程，正栅压作用下的PMOSFET器件特性退化会有一定程度的恢复，这是由于在正栅压作用下NBTI反应产物逆向向Si／SiO〓界面处运动从而发生钝化作用造成的。

So there need not only no failure but working in a stably good condition in the ignition system, the using condition and adjust of the use factors are the most important thing for the system performance. The paper analyses the characteristics of electronic ignition system, points out that determinant use factors are mainly the voltage of battery, the occupy-emptiness rate of the ignition signal, the clearance of spark plug, the resistance of high-voltage part, and the cam angle of spark advance.

本论文重点分析了电子点火系统故障特征，论证了决定电子点火系统性能的使用因素主要有电瓶电压、点火信号发生器发出电压信号的占空比、火花塞间隙、高压阻抗、点火提前角，这些因素在点火系使用过程中故障率占点火故障比例最大，故障出现的频率最高，而且有时常因维修调整不当导致点火系统性能变差。

The scattering properties of particles with different shape parameters are simulated respectively in the modes of reflection and refraction. Both in the modes of reflection and refraction, the phase difference of non-spherical particle's PDA signal is the unbiased estimate of the corresponding phase difference of ideal spherical particle, and the standard deviation of angle roughness scale on particle surface impacts little on the distribution of phase difference.

本文通过物理光学的方法分析了非理想球形粒子的散射特性，利用物理光学中的稳相点理论，导出了非理想球形粒子散射光的相位表达形式，分析了非理想球形粒子的形状对PDA信号相位及相位差的影响，建立了非理想球形粒子的尺寸分布与PDA信号相位差分布之间的关系。

Note that the signal amplitude is nominally flat, despite the varying range and angle of incidence associated with scanning.

波的轮廓以中心对称这个PPS系统的特征是扫描过程使接收能量在接受器表面移动的结果。

The effective signal subspace effected on by the angular correlation is analyzed through the array covariance matrix. One distributed source from any degree of angular correlation cannot be generally taken as the independent distributed source.

对于实际应用和理论推导中，源内角度何等相关程度的分布源相关模型可等价于分布源独立或相干模型要做具体分析，不能笼统地认为所有分布源相关模型都用分布源独立模型描述和处理。

It is the input signal, the output is the line, angular displacement.

它输入的是电信号，输出的是线、角位移量。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
