触发

Resultant energetic particles such as electrons and protons rain down near the Earth's poles and impact the air. The impacted air molecules temporarily lose electrons, and when oxygen molecules among them reacquire these electrons, they emit green light.

极光是由来自太阳的高能粒子冲撞地球的磁场所触发的；其结果是高能量的电子和质子在地球的极区附近撞击大气，让被撞击的空气分子短暂失去电子，如果是氧分子重新得回这些电子，就会发出绿光。

They are nonrearrangeable case, complete rearrangeable case, partially rearrangeable case and triggered rearrangeable case. We have an emphasis on the first case for it is a most practical case.

第四章把动态组通信路由优化方案分成四种情况：不允许结构重组、完全结构重组、部分结构重组和触发结构重组，着重研究了第一种优化方案。

D TEAM advocates the premium, healthy, comfortable and relaxable lifestyle.

我们通过天马行空的设计，去触发一种新的生活意识，最终启发人们去追求更为多彩的生活方式！

Exception will occur, because there was no previous exception to reraise.exception will occur, because there was no previous exception to reraise.

如果之前没有异常触发，会因为没可以有重新抛出的异常而生成一个TypeError异常。

The device is retriggerable and resettable, and the control inputs are

此器件可重复触发和复位，而且控制输入端是内部锁存的

From the test,it shows that the trigger solution with saturable pulse transformer is feasible.

实验证明，采用可饱和脉冲变压器触发RSD是可行的。

Magnetic switch is employed as the separator between the main circuit and trigger circuit, and it works well though a saturable inductor is introduced.

用磁开关作为主电路和触发电路间的隔离器能得到较好的测试结果，但也引入了饱和电感这一不利因素。

It is testified if the time reversed seismogram were used as the loading curve and an efficient source of force were exerted on the rock at the seismographic station,then artificial input energy will focus on the hypocenter and cause an intense impact,therefore an earthquake would be touched off.

模拟结果表明，如果将地震图进行时间逆转后，作为加载曲线，在地震台站点上通过一个有效的力源加载于基岩，利用时间逆转效应，可以将人工施加的能量在某一瞬间集中到以往的震源，引起一个强烈的冲击，因而可能触发地震。

The exsitence of liquid affects the structure and composition of fault zone, further changes the stress state, weaken the seismotectonic region and triggers the earthquakes.

这些流体长时间的存在影响了断层带的结构和组成，进而改变了断层带的应力状态，造成了孕震区的弱化，从而触发地震

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％。
