此时

The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。

The iron content of the egg yolk was twice as high as it should have been, too.

蛋黄中的铁含量也高出正常含量的两倍，但此时铁的问题没有引起注意。

珠儿对母亲劝她安静下来毫不在乎，反倒发出一声怪叫，然后才不吱声，而且也不是出于听话，只因为她那种瞬息万变的好奇心此时被几个新出现的人激励起来了。

In this case you should check if the cursor of the color code electric eye align the position of color code tape.

6 When operating in the "printed" mode, if the color code electric eye did not track the color, the buzzer will give warning.

在"彩印"工作模式下运行时，若色标电眼未追到色，此时蜂鸣器将会报警。

The electrostatic interaction, hydrogen bond and cooperative effect of the eightmembered ring were formed simultaneously.

此时吸附剂与内毒素之间存在静电、氢键、疏水相互作用和八元环的协同作用。

As they crept along, stooping low to discern the plant, a soft yellow gleam was reflected from the buttercups into their shaded faces, giving them an elfish, moonlit aspect, though the sun was pouring upon their backs in all the strength of noon.

他们一路搜索的时候，腰弯得低低的，以便看得见地上的蒜苗，阳光照射在毛茛上，从上面反射出来的柔和的黄色光线投射在他们背朝阳光的脸上，使他们看上去有些像在月光照射下的虚无缥缈的样子，尽管此时的太阳正在用中午的全部力量把光线照射在他们的背上。

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