查询词典 medium

In the study of isospin-dependent nucleon-nucleon elastic crosssections in nuclear medium we find the medium correction of nucleon-nucleon scatteringcross sections is also isospin dependent,〓 depends on the baryon density weakly and 〓 depends on the baryon density significantly.

用QHD-Ⅱ模型研究了介质两体截面的同位旋相关性，研究结果表明截面的介质修正也是同位旋依赖的：中子-质子介质截面对核密度的依赖很弱，而中子-中子的介质截面对核密度的依赖很强。

The longest lifetime component in PALS results is ascribed to the annihilation of positronium in cavities of PS sample. It is found that 80% of the positrons implanted in PS film have formed positronium atoms. PALS results show that the lifetime of ortho-Positronium has small value when the sample was in oxygen gas medium compared with those in other medium.

正电子湮没寿命谱测试结果表明，样品中存在长达40ns的电子偶素湮没成分，并且进入多孔硅膜层的正电子约有80%形成电子偶素，具有非常高的电子偶素产额；在氧气气氛下，由于气体导致o-Ps发生自旋转化猝灭是使多孔硅样品中电子偶素寿命缩短的主要原因。

After purification, cells were cultured in Ham's F12 medium or Ham's F12 hormonally defined medium for different time respectively, and the specific expression of cytokeratin 18 (CK18) and alpha-1-fetoprotein in the primary cultures was characterized by indirect immunofluorescence method. Cell growth and proliferation was checked by MTT method.

观察培养细胞的形态特征，免疫荧光法检测胚胎肝细胞角蛋白18 (Cytokeratin 18， CK18)和甲胎蛋白(alpha-1-fetoprotein， AFP)表达， MTT法检测细胞活力和增殖能力。

At the initial observation of leakage, judge on the leaking part of the foundation, and then manually set car observation, if the leakage were no significant changes in static and dynamic sealing ring has questions; such as disk when leakage can be concluded that there is significant change are moving , static friction ring problem exist; such as leakage of medium along the jet axis, the actin ring seal problem exist mostly, leakage to the surrounding medium or from the water spray cooling holes in the leakage, the many for the static seal ring failure.

在初步观察泄漏量、判断泄漏部位的基础上，再手动盘车观察，若泄漏量无明显变化则静、动环密封圈有问题；如盘车时泄漏量有明显变化则可断定是动、静环摩擦副存在问题；如泄漏介质沿轴向喷射，则动环密封圈存在问题居多，泄漏介质向四周喷射或从水冷却孔中漏出，则多为静环密封圈失效。

Leakage in the initial observation to determine the basis of the leakage site, and then manually set car observation, if the leakage were no significant changes in static and dynamic sealing ring problem; such as the disk when there are significant changes in leakage can be concluded that the dynamic , static friction ring problems; such as leakage of medium along the jet axis, while moving most of Central ring problems, leakage to the surrounding medium or from the water spray cooling holes in the leakage, the seal ring for static failure.

杂质泵安装静试时泄漏机械弥缝安装调试好后，一般要进行静试，察看泄漏量如泄漏量较小，多为动环或静环弥缝圈存在问题；泄漏量较大时，则表白动、静环磨擦副间存在问题在开端察看泄漏量、判断泄漏部位的根蒂根基上，再手动盘车察看，若泄漏量无明显变化则静、动环弥缝圈有问题；如盘车时泄漏量有明显变化则可下定论是动、静环磨擦副存在问题；如泄漏介质沿轴向喷洒，则动环弥缝圈存在问题居多，泄漏介质向四周喷洒或从水冷却孔中漏出，则多为静环弥缝圈失效此外，泄漏通道也可同时存在，但一般有主次区分，只要察看细致，认识结构，一定能正确判断
