In the tumor model of pyretic syndrome, contents of PGE2、IL-8、TNF-α、and COX-2 proteinum high and contents of ICAM-1 and VEGF proteinum was low. There are the inhibited action on tumor in the group of Xiaotansanjie、Qingrexiaotan and chemotherapy. Results The the tumor model of pyretic syndrome was successful to be established.

结果成功建立热邪干预下S180肉瘤模型，并且此模型动物PGE2水平升高，符合热邪本质；在热邪干预下S180肉瘤模型中炎性因子PGE2、IL-8、VEGF以及COX-2表达明显增强，而TNF-α、ICAM-1表达增强不明显。

Temporal and spatialcorrelation of Soil moisture under vertical direction was affected by some factor such asmeteorology, land use and fertilization measures. All siol moisture in different layers hastemporal and spatial correlation when soil moisture fluctuates of surface layer becausestability, but influence ability of each factor is not the same. For example, meteorologyhas most strong impact on temporal and spatial correlation of soil water content.

在气象条件较稳定的情况下，不同植被覆盖和不同施肥措施下各土层含水量之间都具有较强的时空相关性，随着气象条件波动加剧，各土层土壤含水量的时间相关性和空间相关性都降低；植被因素相对气象条件对各土层含水量的时间自相关性影响较小，而对各土层土壤含水量之间的空间相关性影响较大，裸地和农田各土层土壤含水量之间的空间相关性相对林地和草地较弱；不同的施肥水平都削弱了土壤各土层含水量的时空相关性。

Continuing inferiorly and anteriorly , the main trunk runs superficial to the internal carotid artery but deep to the jugular vein , external carotid artery , and styloid process to the deep surface of the stylopharyngeus muscle , which it innervates . The glossopharyngeal branch to the pharyngeal plexlus leaves the nerve trunk by the time it has crossed the stylopharyngeus muscle , and passes anteriorly and inferiorly between the internal and external carotid arteries to the main trunk to join branches of the Vagus Nerve and the cervical sympathetic nerves to form the pharyngeal plexus on the middle constrictor muscle at the level of the hyoid bone .

舌咽神经主干继续向下、向前走行于颈内动脉的表面、颈内静脉、颈外动脉及茎突的深面，横过茎突咽肌深面，绕该肌中部下缘弯向前行，并发出分支支配该肌，穿过茎突咽肌后，舌咽神经的分支一咽支脱离主干，向下向前走行于颈内动脉及颈外动脉分叉处，与迷走神经的分支及颈交感神经的分支一起组成咽丛，咽丛位于舌骨水平的咽中缩肌上。

The agitation power consumptions in boiling systems decrease uniformly with the increase of agitation speed, whereas the relative power demand (RPD-the ratio of agitation power input of HEDT for gassed system to that for ungassed system and under the same agitation speed) can maintain at a high level for high gas loadings even when the impeller is operating with a high impeller tip speed. The gas hold-up in the boiling system is much lower than that in the cold gassed system, and the gas hold-up in boiling system increases at first and then decreases with the increase of the agitation power consumption per liquid mass P(subscript m. It implies that the boiling three-phase system has a maximum gas hold-up point. The changes of nucleation site of vapour bubble and the character of suspension of the solid particles with the rotational speed of the impeller are responsible for those behaviors mentioned.

在沸腾条件下，搅拌功率消耗随着搅拌转速的增加有所下降，但HEDT桨具有较高的载气能力，即使在高叶端线速度下，相对功率消耗仍能保持在较高的水平；沸腾体系的气含率随单位质量流体输入功率的增加表现出先增后减的规律，即存在气含率的极大值，蒸汽成核位置和固体颗粒悬浮特性随搅拌功率增加而改变是造成上述行为的主要原因；沸腾体系中的气含率远远低于常温通空气体系。
