PartⅡFeasibility of vitrifying normospermic samples using droplets without cryoprotectans Objective Discuss the feasibility of droplets to vitrify normospermic samples without cryoprotectants. Methods Normal prepared sperm were frozen by conventional freezing protocol and non-cryoprotectant freezing in droplets respectively. Freezing in droplets means freezing sperm in every 10ul drop. After thawing, compared the two groups'sperm mobilities.

第二部分微滴法无保护剂玻璃化冷冻正常精子的可行性探讨目的探讨在不添加冷冻保护剂的情况下微滴法玻璃化冷冻正常精子的可行性方法收集16份正常精液标本，上游处理后分别进行慢速冷冻和微滴法冷冻，微滴法即用拉细巴氏管将标本形成10ul的液滴，直接投入液氮内冻存，复苏后镜检其活动率。

In addition, the computational evaluations indicate that the heat transfer enhancement of delta winglet for aligned tube bank heat exchanger is more significant than that for staggered tube bank heat exchanger, the heat transfer enhancement of delta winglet with the attack angle of 45° is more obvious than that of 30°; the delta winglet with the attack angle of 45° leads to an increase in pressure drop, while the delta winglet with the attack angle of 30° results in a slight decrease.

另外计算还发现：三角形小翼对顺排换热器的强化换热效果好于对叉排换热器的强化；冲角为45°的三角形小翼强化换热效果好于冲角为30°的三角形小翼；冲角为45°的三角形小翼导致空气压降提高，而冲角为30°的三角形小翼则可使压降有所减小。

The demulsification mechanism of PAMAM belongs to displacing mechanism. Acylamino groups of PAMAM of integral having strong polarity can take place chemical adsorption with the materials of strong polarity in the exterior of oil drop and be participated in into the membrane, which will result in adsorbed crude surfactant and other active materials to be partially displaced and reduce the intensity of interfacial film between oil and water.

其机理是由于整代的PAMAM具有强极性的酰胺基团，能与油滴表面的强极性的物质发生化学吸咐作用，参与成膜，能把原来吸咐的天然活性剂分子和其它活性物质部分顶替，削弱油水界面膜强度。

The peculiar aspect of JaMBW, however, is to take advantage of the foremost developments in computer science in order to deliver information in a way simple to use. The latter includes, therefore, point-and-click, drag-and-drop, plug-and-play. Most of these requirements are met by the use of Java programming language conformant to the JDK1.02 specifications.

JaMBW是一个分子生物学软件包，功能包括：序列格式转换、求序列的补体序列与逆序列、将DNA序列翻译成蛋白序列、序列分析、多序列比较、特征位点查找、3维分子结构查看、PCR引物设计、缓冲液设计等功能，包含了分子生物学研究常用的一些操作。

The male dragon that has invested some game business is achieved send father, copartner is checked stand to express in the rich guest 8 years November,"Inchoate poineering investment is to be in ' dead cereal ' in skip extremely ", a bit crackbrained drop " dead cereal " throw a have one's body smashed to pieces.

Ah! Feel better is much! Later, I of happy to dance with random fan of chair cushion houseful, pray this effluvial can drop off at once..., such, be in next ten minutes of less than, I am putting fart ceaselessly at the same time, at the same time ceaseless fan is worn chair cushion, eventually, when I hear her to say good-bye in the phone, the air in house and my abdomen already a lot of!

The proportion of reserves of low permeability gas reservoirs to nonproducing reserves is larger and larger in China at present. And the depletion way of production is used in low permeability gas reservoir currently, so the gradual drop of formation pressure during the exploitation will result in the deformation of rocks, which makes the reservoir porosity and permeability decline.

目前中国低渗透气藏的储量占未动用气藏储量的比重越来越大，而低渗透气藏一般都采用衰竭式开采，在生产过程中地层压力逐渐下降，导致储层岩石变形，使得孔隙度和渗透率降低，从而导致低渗透气藏开发效果变差。

To: Mao, PetriPetri, I think you are misunderstanding. As it has be scheduled in CCB, I am afraid drop it would induce reapproval and delay time. Actually I am not interested in changing existed files. It is a stupid method not only in Intel but also other companies.
