Therefore appropriate amount of Ca(superscript 2+) or 504 (superscript 2-) can improve chemical imbibition and recovery factor of core.

添加适量的Ca(上标 2+)或SO4(上标 2-)，可以促进岩心的化学渗吸，从而提高岩心渗吸采收率。

It was isolated from the mosquito stomach HIV, found that absorption of the mosquito's blood after AIDS patients, HIV can survive in the mosquito stomach three to four days, but the amount of virus in mosquitoes can cause the number of HIV transmission is not clear, and the mosquitoes In a suction blood, at least three to four days no longer vampire bites, and some died soon; Some people also said: mosquitoes but the remnants of blood containing HIV will be transmitted to humans.

有人从蚊子胃内分离出HIV，发现蚊子吸了艾滋病病人的血之后，HIV可在蚊子胃内存活3~4天，但蚊子体内带毒量的多少才可引起HIV传播尚不清楚，而蚊子在吸一次血之后，至少3~4天不再叮咬吸血，有的很快死去了；又有人说：蚊子嘴上残留的血液含有HIV会传染给人。

Aiming at the problem that the seeds picked up by the suction plate of the seed metering device cannot accurately fall into the seed pit opener as well as into the seed pit, an innovated seed metering device on which the seed dropping angle can be adjusted within a certain range and a new testing stand have been developed in accordance with the mathematical calculation model that had 'in accordance with the mathematical calculation model that had been established previously.

本论文根据2BQM-2型气吸式精量铺膜播种机的结构和工作原理，针对该机在实际播种中，吸种盘吸出的种子不能满足准确地落入在膜上滚动开穴的鸭嘴内，并及时地排入到鸭嘴所成的穴孔内的设计要求，进行了一定的试验研究，利用已建立的计算数学模型，设计新的试验台，改进排种器，使排种器的落种角度可以在一定的范围内调整。

Experience of feeling: like needles, but not needles, not "bar" but smoke, a small magnetic control head like a vacuum cleaner, in the skin gently on the spot at a suction, it will be of melanin in the skin absorption to the skin surface, the skin seems to have been slightly "sticky" a moment, there is no pain, a spot so easily have been taken down, each time taking a spot no more than 2 seconds.

体验感受：像针头但不是针头，不是&扎&而是吸，小小的磁波控头就像一个吸尘器，在皮肤上的斑点处轻轻一吸，就将在皮下的黑色素吸至皮肤表层，皮肤好像轻微地被&粘&了一下，没有痛感，一个斑就这样轻松地被取下来了，每取一个斑的时间没超过2 秒钟。

In this paper,the raft is approximated by a thin plate with regular shape at first.Then the floating raft system is divided into several subsystems,such as plate raft,elastic foundation,etc,which are respectively modeled by four-parameter net method.After that,dynamic absorber and active absorber are put into a uniform frame to obtain the model of plate raft subsystem coupling with them.At last,according to the force and velocity relationship among each subsystem\'s interfaces,the entire plate floating raft system is modeled by subsystem structural admittance synthesis method.As the main structure of floating raft system is elastic,it is inevitably to study the optimization of actuators\' mounting positions before designing control law.In this paper,two new criterions are proposed for it.

本文首先将浮筏的中间筏架用一个规则形状的薄板近似；然后再将浮筏系统分解成若干个子系统，如板式筏架子系统、弹性基础子系统等，运用四端参数网络建立了它们的动力学传递方程，传递特性由导纳矩阵描述；接着，将动力吸振器和主动吸振器的(来源：ABC90论文00网www.abclunwen.com)分析统一于一个框架内，获得了与吸振器耦合的板式筏架子系统的动力学传递特性；最后，根据各子系统在各界面上的作用力和速度的相互关系，通过子系统结构导纳综合方法获得了整个板式浮筏系统的动力学传递方程，并在此基础上获得了系统的力传递函数模型。

The pump mounting height should be allowed to smoke on a high vacuum suction pipe loss deduction after the head, the rest of that part of the value, it is highly absorbent to overcome the actual terrain.

而水泵安装高度应该是允许吸上真空高度扣除了吸水管道损失扬程以后，所剩下的那部分数值，它要克服实际地形吸水高度。

And the pump mounting height should be allowed to deduct a high vacuum suction on the suction pipe head loss, the remaining portion of the value, it is to overcome the actual water height of the terrain.

而水泵安装高度应该是允许吸上真空高度扣除了吸水管道损失扬程以后，所剩下的那部分数值，它要克服实际地形吸水高度。

Experience of feeling: like needles, but not needles, not "bar" but suck, a small magnetic control probe like a vacuum cleaner, suction in the freckle of skin gently, it will absorption subcutaneous melanin to the skin surface, the skin seems to have been slightly "sticky" a moment, there is no pain, a freckle so easily have been removed , taking a freckle each time no more than 2 seconds.

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
