查询词典 permeability

With the development time extension, the development effect worse gradually of Chaoyanggou oilfield, There is some low permeability thin oil that traditional production techniques can not realized in Fuyu and Yang da cheng zi layer of Chaoyanggou oilfield. The crude oil viscosity is high; the relationship between viscosity and temperature is sensitive. The viscosity has big fluctuating along with the temperature change. According to the development experience of inspissated pool and the research results of numerical simulation by STARS, thermal recovery technique is an efficient method used to improve the development effectiveness of low permeable and high viscosity blocks.

The less the warp yarn interlaces with the weft yarn, the better the air permeability. However, the luster has great influence on the cover tightness.

涤纶织物的光泽度与紧度密切相关，紧度小，光泽度也较小；紧度在一定范围(50%~70%)时，光泽度基本无变化；紧度超过一定值，光泽度明显变大。

The relatively slow whole-body distribution of lactated Ringer's solution, which boosts the plasma volume expansion during and for up to 30 min after an infusion, is probably governed by a joint effect of capillary permeability and differences in tissue perfusion between body regions.

乳酸林格式液在其输注期间和输注后的30 分钟内对血浆起到扩容作用的，对于它相对缓慢的全身分布，可能是由于毛细血管通透性和不同身体区域间的组织渗透性差异这两者的联合效应。

After air seasoning,workblanks for longitudinal permeabilitymeasurements are sawn and surfaced in 2.0-by 2.0-by 10.0-cm and those for radial andtangential permeability are lathed into disks with a 1.9cm diameter and 1.5cm thick.

试件毛坯在室内气干半年之后，纵向渗透试件加工成横截面为2.0×2.0cm长为10.0cm的长条状，径向渗透试件和弦向渗透试件加工成半径为1.9cm厚度为1.5cm的圆盘状。

The results indicated that the lignified seed shell had a negative impact on water permeability of seeds,but it was not the main reason for seed dormancy.

结果表明：(1)美国桂花种子木质化种壳对种子的吸水透性有一定的阻碍作用，但不是引起种子休眠的主要原因；(2)美国桂花种子的胚没有休眠，离体胚在光照培养7 d开始萌动；(3)胚乳被严密包裹的机械作用使胚无法获得萌发所必需的水分和氧气，这可能是导致种子休眠的最主要的原因。

At the present, to the research flowing through porous media in most of low permeable reservoirs, the relation between permeability and start-up pressure gradient is dained by core flooding experiment, which is time-consuming and highly costed, and also, the factors taking into consideration are simple.

针对目前大多数低渗透油层的渗流研究都是通过岩芯驱替实验得到渗透率与启动压力梯度的关系，不仅费时费工，而且考虑的因素比较单一的问题。

In order to reveal the leaves senescence of spring wheat grown with plastic film mulches, the content of chlorophyll, protein, MDA and the cell membrane permeability of the leaves for spring wheat grown with and without plastic film mulches were determined by using simulated tube cultivation.

为了揭示春小麦在地膜栽培条件下是否早衰的问题，采用管栽模拟试验的方法，研究了地膜覆盖和露地栽培条件下春小麦叶片的叶绿素、蛋白质、叶片丙二醛含量和细胞质膜相对透性的变化。

Almost all CF was released from Dansyl-PE by CTX-IX that osmosed the Dansyl-PE liposome like detergent; CF releases from PE or PS liposome induced by CTX-IX were related with both of CTX-IX and phospholipid concentrations, this indicated that the phase seperation should be a reasonable mechanism for CF permeability of PS or PE liposome in the presence of CTX-IX rather than CTX-IX channel formation on the membrane. CTX-IX influence of CF release of PC liposome was very slight. CF release from Dansyl-PE、PE or PE liposome in response to CTX-IX could be inhibited by Ca〓.

CTX-IX对靶脂如此种种强烈的作用，使得它引起含Dansyl-PE脂质体CF的泄漏犹如击污剂那样强烈；引起含PS或PE脂质体CF渗透的增加为一个与CTX-IX及磷脂浓度有关的二级反应过程，这种动力学特征提示渗透性增加的机制可能是CTX-IX在脂膜上产生的脂质分子相分离，而不是CTX-IX脂膜上形成通道；CTX-IX对PC脂质体渗透性几乎没有影响，而对上述脂质体渗透性增加作用均可被Ca〓所抑制。

However, due to not clear knowing to the definition of concrete durability and different understanding to the so called "high performance", people always lose their way in the process of design and construction, for example, overemphasizing the property of high strength and permeability, but ignoring the crack problem that appears more easy, more serious, and more dangerous to concrete structure.

然而，由于对混凝土的耐久性概念认识不清，以及对混凝土所谓&高性能&的理解存在差异，往往在设计和施工过程中陷入很多误区，如过分追求高强度、低渗透性能等，却忽视了随之出现的更易产生、更为严重、同时对混凝土结构整体性潜在危害更大的裂缝问题。

Because the C is so well perfused, permeability is generally the major determinant of the drug distribution rate.

中枢神经系统的血液灌注极佳，一般说来，通透性是药物分布速率的主要决定因素。
