Has the scientist to do the experiment: When noise intensity when 90 decibels, in retina's rod cell difference radiance's sensitivity starts to drop, distinguishes the time which the weak light responded also to lengthen; When noise when 95 decibels, some 2/5 person mydriasis; When the noise amounts to 115 decibels, the eye reduces 20% to the radiance compatibility.

有科学家做过实验：当噪音强度在90分贝时，视网膜中的视杆细胞区别光亮度的敏感性开始下降，识别弱光反应的时间也延长；当噪音在95分贝时，有五分之二的人瞳孔放大；当噪音达到115分贝时，眼睛对光亮度的适应性降低20%。

When legal request, I am willing to defend the US to take up the weapon, when legal request, I will make the noncombatant for the US the military service, when legal request, under I in the government officials will direct do the important work for the country.

当法律要求时，我愿为保卫美国拿起武器，当法律要求时，我会为美国做非战斗性之军事服务，当法律要求时，我会在政府官员指挥下为国家做重要工作。

The emulation result shows that the error of polarizer rotation angle almost does not influence nonlinearity when elliptic polarization of laser beams exists; when the error of rotation angle of polarizing beam splitter exists, the second-harmonic nonlinearity caused by the error of polarizer rotation angle will not increase, but the first-harmonic nonlinearity will increase greatly.

仿真结果表明，当存在激光束椭圆偏振时，检偏器旋转误差对非线性误差的影响很小；当存在偏振分光镜旋转误差时，检偏器旋转误差引起的非线性误差不增加二次谐波分量，但增大了非线性误差一次谐波分量，严重影响非线性误差的大小，当偏振分光镜旋转误差为3°时，检偏器旋转误差从0°增加到5°，非线性误差从0.14 nm增大到0.97 nm。

知已当你伤心落泪时、当你孤独无助时、当你踌躇无措时首先想起的那个人，他就是

It is found that the current of oil flow electrification is maximum, minimal and intermediate in the case of pressboard paper, PTFE and metal iron respectively. Composition of new and aged oil is analyzed by DX-4 electron disperse analyzer.

通过固体材料表面特性对油流带电影响的研究，发现当固／液界面中的固体为绝缘纸板时，油流带电电流最大；当固体为聚四氟乙烯时，油流带电电流最小；当固体为金属铁板时，油流带电电流介于两者之间。

When motion is towards the location of the addressee,come is much preferable to go in English while both laiand quare common in use in Chinese.When motion is towards the location of the addressee at a past time,laimust be used in Chinese if the addressee is there at the time of utterance while qumust be used if the addressee is not there at the time of utterance.By contrast,come is used in English either when the addressee is there or when he is not there at the speaking time,while go is only used when the addressee is not there at the time of utterance. When both the speaker and the addressee serve as the figure,which is indicated by the phrases like with me/us/you in English and the phrases like he ni,he nimen,gen wo,gen womenin Chinese,come is much preferred to go for the figure"s motion,while in the same context,quis used for the figure"s motion.What"s more,come is more frequently used to indicate the figure"s movement towards a place where neither the speaker nor the addressee is located at the time of utterance,while quis often used in Chinese in the same case.

当移动体朝向听话人所在方位移动时，英语多用come，汉语可用"来/去"；当移动体在一个过去的时间朝向听话人所在方位移动时，汉语可用"来"表示听话人在说话时间仍在位移参照点，用"去"表示听话人在说话时间已不在位移参照点，而英语在两种情况下都可用come，用go则表示听话人在说话时间已不在位移参照点；当说话人和听话人一起作为移动体而句中主语只是说话人或听话人一方时，英语多用come，汉语多用"去"。

During annealing the ribbons with 5% at Pd, Zr2Ni crystallizes first, and then the residual amorphous matrix transforms into Zr2Pd.

当Pd的加入量为5at%时，初生相仍为Zr2Ni，随后部分残留非晶转变为Zr2Pd；当Pd的加入量达到10at%时，初生相为Zr2Ni和少量Zr2Pd并存；当Pd的加入量达到20at%时，初生相为明显的Zr2Pd。

And when you are upset they stand by you, when you are in a good mood they happily bask in that moment, and when the world seems to crumble at the seams they scurry to patch it up.

还有，当你失意时他们会陪在你身边，当你心情愉快时他们也会感到快乐，当你眼前的世界即将崩毁时，他们也会立即为你填补。

You touch it when you hike through the hills and stumble across the ruins of a deserted shieling.

本分工作外，我有个习惯——收杀，你能感觉到历史的气息；当徒步穿越山岭，暮然发现一座牧棚的废墟时，你能触摸到历史的脉动；当饱经岁月洗礼的石砌古堡塔楼映入眼帘时，你能注视到历史的沧桑；当激昂跃动的苏格兰边区歌谣和令人魂牵梦萦赫布里底的旋律响起时，你能聆听到历史的诉说。

Brad Paisley -- Letter To Me 写给自己的信 If I could write a letter to me And send it back in time to myself at 17 First I'd prove it's me by saying look under your bed There's a Skoal can and a Playboy no one else would know you hid And then I'd say I know it's tough When you break up after seven months And yeah I know you really liked her and it just don't seem fair All I can say is pain like that is fast and it's rare And oh you got so much going for you going right But I know at 17 it's hard to see past Friday night She wasn't right for you And still you feel like there's a knife sticking out of your back And you're wondering if you'll survive You'll make it through this and you'll see You're still around to write this letter to me At the stop sign at Tomlinson and Eighth Always stop completely don't just tap your breaks And when you get a date with Bridgett make sure the tank is full On second thought forget it that one turns out kinda cool Each and every time you have a fight Just assume you're wrong and dad is right And you really should thank Mrs.

如果我能写封信，寄回给十七岁时的自己。那里有一个啤酒罐和一本"花花公子"，没人知道你把它们藏在那儿。然后我要说那很令你难受，当你交往了七个月的女孩儿与你分手，是啊我知道你好喜欢她，那似乎不很公平，但我只能说那是短暂的痛苦而且也极少发生。哦，你有着美好的未来，但我知道十七岁时很少有谁人去想周五晚上以后的事儿。她不适合你，你却依然心如刀绞，不知能否活下去。但最终你能熬过这一切而且你会看到你仍然好好的并写这封信给我。在Tomlinson与第八街的交口处，停车信号时一定要将车停住而不仅仅是点一脚刹车。当你和Bridgett约会要确信油箱是加满的，再仔细想想，别太在意了，那个女孩儿并不很酷。每一次的争执，就只当你是错了而爸爸是对的。而且你真要好好感谢Brinkman老师，她为你花费了那么多额外的时间，好像她看到了地下的钻石，她不停地打磨直到你闪闪发光。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
