屏障

Need to know, skin and mucosal barriers, is to protect the body's first barrier layer, and the same armor, resistant to the outside world to prevent pollution, infection and so on!

要知道，皮肤及粘膜屏障，是保护人体的第一次层屏障，和铠甲一样，耐防止外界的污染、感染等等！

The results of the TEM showed the same respiration epithelium in the inside gill and the gill filament, it is flat, the cytoplast of the epithelium contained of the rough endoplasmic reticulum, vacuole and mitochondrion in rich; the blood-gas barrier is formed of the monolayer epithelium, the endothelial cell and the basilar membrane between the both, following the development the blood-gas barrier attenuate gradually.

电镜结果表明花背蟾蜍外鳃与内鳃具有相同的呼吸上皮，为扁平状，上皮细胞质中富含粗面内质网及空泡和线粒体；气血屏障由由单层上皮细胞，内皮细胞以及二者之间的基底膜构成，随着个体的发育，气血屏障逐渐变薄。

Hooper, previous studies by his group and other researchers have shown that blood-brain barrier permeability is critical in the development of MS.

为了研究血脑屏障的通透性，他和他同事们观察到多发性硬化进展过程中血脑屏障的损伤起到关键作用。

The diffraction attenuation of infinite thin sound barriers to point sources are calculated,and the influences of Sound source and receiver positions,noise frequency and reflection from the ground are ana- lyzed.

数值模拟方法主要借助于计算机计算，不受实地条件的影响，因而能快速得出分析结果，为声屏障的设计提供参考依据，以便探讨和设计更多的高效声屏障形式。

Methods: Mice were inoculated intracerebrally with herpes simplex virus type1(HSV-1) to form herpes simplex encephalitis. MMP-9 gelatinolytic activity was assessedby zymography from brain tissues 3 days and 7 days after HSV-1 infected.

第一部分单纯疱疹病毒性脑炎相关病理机制的研究实验一MMP-9在单纯疱疹病毒性脑炎中的表达及对血脑屏障的影响目的：研究单纯疱疹病毒感染小鼠脑组织后MMP-9的变化及对血脑屏障通透性的影响。

And the Cologne group's delicate measuring instruments showed that the signal was arriving earlier with the barrier in place – it was crossing the gap between transmitter and receiver faster than light speed.

而且， 科隆的研究小组利用精密的仪器检测到，当信号通过屏障的时候，在屏障里面的传播速度要高于光速。

Neuroglia, the basic integrant of blood-brain-barrier is defective in brain metastatic tumor tissue, thus there is no blood-brain-barrier existing in brain metastatic tumor lesions.

脑转移癌组织缺乏构成血脑屏障的神经胶质膜，血管内皮也非均一的紧密连接，所以脑转移癌组织不存在完整的血脑屏障。

Objective To study the dynamic changes of transendothelial electrical resistanceonourin vitromodelofbrain blood barriermade from primary culture ofBALB/cmouse brainmicrovascu-lar endothelial cells,and to explore the relation between TEER and BBB permeability,and searchfor the best culture condition.

目的 应用原代分离培养BALB/c小鼠脑微血管内皮细胞(brain microvascular endothelial cells， BMVEC)建立体外血脑屏障模型，探讨跨血脑屏障(blood brain barrier，BBB)电阻与屏障渗透功能的动态关系以及最佳构建条件。

According to the development characteristics of regional caprocks,great efforts have been made to analyse the effect of it on oil and gas accumulation and preservation in different aspects. We consider regional caprocks to be the good barriers to prevent oil and gas in free phase from escaping. If uncompacted and possessing abnormal pore fluid pressure,regional caprocks are the barriers to prevent oil and gas in water dissolving phase from escaping.

根据区域性盖层的发育特征，从不同侧面对其在油气聚集与保存中所起的作用进行了深入分析，认为区域性盖层通常是阻止游离相油气逸散的良好区域物性屏障；如果其欠压实，具异常孔隙流体压力，它还可以成为阻止水溶相油气逸散的区域压力屏障；如果其再具生烃能力，还可以成为阻止扩散相天然气逸散的区域浓度屏障。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。

You were hired to drum up new business, so go and do it.
