先在

From 24h to 96h, the removal rates of NH4 -N in every experimental group were all negative indicated that when being exposure to Hg2 , Egeria najas not only couldnt remove NH4 -N from water, but also would increase its concentration.

在24-96h的处理时间内，各实验组中细叶蜈蚣草对NH_4~-N的去除率基本为负数，说明在Hg~(2 )的作用下，细叶蜈蚣草不仅不能去处水中的NH_4~-N，相反还可能使水中的NH_4~-N增加。96h内水体NO_3~--N含量变化无明显的规律性，而细叶蜈蚣草对水体NO_3~--N的去除率变化规律比较一致，先上升后下降最后比较平稳。

We need to be certain they're holding Elan before we mount a rescue operation.

在我们开始拯救行动之前，先要确定Elan是否在他们手里。

Before bringing any machines that operate electrically , check to determine if they can be used in the United States

你在把任何电器带到美国之前，应先看看它能不能在美国使用。

To help provide this level of realism, most reverb units allow you to adjust the reverberation time for high frequencies relative to middle frequencies, and introduce some kind of overall equalisation to the reverberation tail.

这里建议大家能在REVERB之前加入一个EQ，先对进入REVERB之前的声音做一次低频清洗运动，然后反复SOLO REVERB的声音，确定低频在经过REVERB后没有变得溷浊模糊。

Ew wrong people before meeting the right one,so that when we finally meet the person,we will know how to be grateful.

在遇到梦中人之前，上天也许会安排我们先遇到别人；在我们终于遇见心仪的人时，便应

Although August Weismann had expressed doubts about the theory earlier, it did not fall out of scientific favor until the 1890s, when a series of experiments by James Cossar Ewart in Scotland and other researchers in Germany and Brazil failed to find any evidence of the phenomenon.

虽然August Weismann最早对这个理论提出了质疑，但是直到1890年代，当James Cossar Ewart在苏格兰，其他研究者在德国、巴西等做的一系列的实验未找到任何先父遗传现象的证据之后，这个理论才淡出科学的视野。

Lthough August Weismann had expressed doubts about the theory earlier, it did not fall out of scientific favor until the 1890s, when a series of experiments by James Cossar Ewart in Scotland and other researchers in Germany and Brazil failed to find any evidence of the phenomenon. The result obtained by Morton could probably be caused by the display in the offspring of the recessive genes inherited by the Morton's mare from her parents or grandparents

ugust Weismann对理论表示怀疑(也就是你回应提到马交配的实验，在本段的上半部有提及我就不引用了)但这理论始终得到学界支持，直到James Cossar Ewart在苏格兰，德国，巴西所做的系列实验都无法发现有关现象的根据；Morton观察到的，可以说是马遗传了亲代或祖父母的隐性基因，并表现出性状也就是最初实验马交配发表先父遗传的人

If there was a horse-race, you'd find him flush or you'd find him busted at the end of it; if there was a dog-fight, he'd bet on it; if there was a cat-fight, he'd bet on it; if there was a chicken-fight, he'd bet on it; why, if there was two birds setting on a fence, he would bet you which one would fly first; or if there was a camp-meeting, he would be there reg'lar to bet on Parson Walker, which he judged to be the best exhorter about here, and so he was too, and a good man.

赛的要是马，收场的时候他不是赢得满满当当，就是输得一干二净；如果斗的是狗，他赌；斗的是猫，他赌；斗的是鸡，他还赌；嘿，就算有两只鸟落在篱笆上，他也要跟你赌哪一只先飞；屯子里聚会他必到，到了就拿沃尔克牧师打赌，他打赌说，沃尔克牧师布道在这一带是头一份；那还用说，他本来就是个好人么。

The results were as follows: Being infected virus, the electrolyte exosmosis rate of tobacco leaf was increased , while the increase rate of the leaf being injected ion was less than that of the control. The activities of SOD?

结果表明：病毒侵染后烟草叶片电解质外渗率增大，但离子注入后烟草的电解质外渗率增幅小于对照；病毒侵染后烟草叶片的超氧化物歧化酶、过氧化物酶、硝酸还原酶的活性及叶绿素含量均有所下降，但离子注入后烟草的上述酶活降幅较小；CAT活性在接毒后呈先低后高的变化，而对照在接毒后 10天该酶活性高出离子注入烟草 2倍多，随后剧降，到接毒 2 5天时仅为离子注入处理烟株 1/ 2。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
