查询词典 length of time

Movement trajectories of electrons under complex field and state parameters when electrons return to the dielectric surface are obtained by simulation,such as impact energy and return time. Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron,and there is an emergence angle in which the electron has the maximum trajectory length and impact energy.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron, and there is an emergence angle in which the electron has the maximum trajectory length and impact energy, Impact energy will increase and return time will reduce as increasing the amplitude of electric field, and both parameter would oscillate with the phase of electric field, which can essentially explain that multipactoring electron number oscillates in twice the frequency with the increase of microwave frequency, electron trajectory will change from parabolic-like movement to complex oscillation.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

The result shows that the technical style of our athletes used is that stride length is shorter and stride frequency is larger,the buckjump time of our players is located at the floor level of the foul limit,the knee angel is unwind from touchdown on upright phase,in the sprint phase,the kneel angel is blurry from touchdown to upright phase,the uprightness displacement of body center and vertex are higher than the international athletes, this since stretching to leave a ground of opportune moment to be partial to early and making an effort action insufficiency with leg driving of the ankle joint relevantly, also with the leg put of front stretch is not enough active at the touchdown ground moment.

结果表明，我国运动员在后半程中，运用的是步长较短，步频较快的技术风格；腾空时间总体上处于犯规时限的下限，膝关节从着地瞬间直至垂直支撑面保持了可见的伸直状态，但在最后冲刺阶段，膝角出现了模糊伸直过程；身体重心垂直位移、头顶位置上下起伏均高于世界优秀运动员平均水平，这既与踝关节后蹬伸展离地时机偏早、用力动作不充分有关，也与着地瞬间摆动腿前摆后的前伸着地动作不够积极有关。

Yi Chen, see sisters face boring thing that has not completed Linger on the open-ended enlighten up, henny pulled my mother said something in her ear, before we know Yang months looking for her mother talked about something else to think again is a new case, evidently that even a headache than Linger, easy to pick up the morning to help their child so that he went to sleep so that Lei care henny a will, his sister's side went to her to study, and two sisters chat at length quite speculative, Lei discussed from time to time to hear the sound coming from the opposite direction, not the name of sleepy perception, see henny asleep after the room behind closed doors and into the back to sleep.

易晨见妹妹表情沉闷以为灵儿的事没有办妥，就漫无边际的开导了起来，henny拉着妈妈在她耳边说了一番，才知道杨晓月的妈妈找她谈了别的事情，想到又是一个新的案子，看样子比灵儿这个还要头疼，易晨帮孩子收拾好让他睡觉后便让何磊照看henny一会，自己走到妹妹的身边让她去了书房，两个姐妹长篇大论聊得相当投机，何磊不时听到讨论的声音从对面传来，不知觉中打着瞌睡，见henny熟睡后便回了房间关上门进入了梦乡。
