Results show that detonation velocity of compound explosive declines from 3100 m·s-1 to 2100 m·s-1 when mass ratio of attenuant rises from 20% to 60%(explosive loading thickness is 30 mm ),and the density of compound explosive rises from 0.615 g·cm-3 to 0.76 g·cm-3 when mass ratio of attenuant rises from 20% to 50%.

结果显示，当稀释剂含量从20%增加到60%时，混合炸药的爆速(药厚：30 mm)由3100 m·s-1降到2100 m·s-1，炸药的密度也由0.615 g·cm-3增加到0.76 g·cm-3(稀释剂含量： 20%~50%)；稀释剂含量为50%的混合炸药，当药厚在25~50 mm范围内时，爆速保持在2300~2360 m·s-1之间。

Check valves are automatic valves that open with forward flow and close with reverse flow.

止回阀是一种自动化运行的阀门，这种阀门当流体向前流动时处于开启状态，而当流体倒流时则处于关闭状态。

When diving sewage pump motor power 7.5kW or greater than or equal to greater than or equal to the outlet pipe diameter DN100, the pump can be fixed Autotransformer device; when diving sewage pump motor power 7.5kW or less than the outlet diameter is less than when DN100 can be established mobile hose installation.

当潜水排污泵电机功率大于等于7.5kW或出水口管径大于等于DN100时，可采用水泵固定自耦装置；当潜水排污电泵电机功率小于7.5kW或出水口管径小于DN100时，可设软管移动式安装。

As you befriend more people, you may find that some are easier to get along with than others.

当你与更多的人成为朋友时，你可能会发现他们其中的一些人是很容易与人相处的，当你总是让别人从你的身上得到好处时，有时候你会意识到那些友谊似乎并不健康，这种友谊就好像是一个人过分的需要甚至是控制你的时候，不断地对你表示不满或者批评你的时候，抑或是把危险和威胁带入你的生活。

It was already candle-light when we reached the hamlet, and I shall never forget how much I was cheered to see the yellow shine in doors and windows; but that, was the best of the help we were likely to get in that quarter For - you would have thought men would have been ashamed of themselves - no soul would consent to return with us to the 'Admiral Benbow.

当我们到达村子时，已是掌灯时分，我永远也不会忘记当我看到窗里橙黄色的灯光时，我是何等的雀跃。但是就这，就像后来被证实的那样，是我们在这个地方所能得到的最大的援助。因为--你会想到，人们该为他们自己感到羞耻--没有人愿意答应同我们一起回"本葆海军上将"旅店。

When fitness satisfies the bimodal distribution, the connectivity distribution of the network satisfies a generalized power-law form.

当Fitness服从一个双模分布时，网络的度分布是一个广义的幂律形式；当Fitness服从均匀分布时，网络的度分布是一个带有对数修正的广义的幂律形式。

When you are feeling down,or when you are in a bind.....

当你情绪低落时，当你被世俗羁绊时。。。。。

Disgrace the memory of the intrepid Duke of Biron, who had sooften braved death in the field, that he wept upon the scaffold,when he beheld the state to which he was fallen, and rememberedunfortunately thrown him!

Is the set of the barycenter of if is a regular triangle, and is the perpendicular bisector of the base if is a nonregular isosceles triangle.

当 为正三角形时，是的重心所成的集合，当为非正三角形的等腰三角形时，是底边的中垂线。

The results show that as the wind is along one leg of the model, the vibrations which are mainly caused by turbulence of oncoming flow are weak, and as the wind is along the angular bisector of two legs, the vibrations induced by vortex are strong.

实验结果表明：当风向顺Y型柱体某一肢时主要是来流脉动引起柱体较弱横向振动；当风向顺Y型柱体两肢分角线时则由涡脱落而引起柱体强烈的横向振动。

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.
