摘 要 该文采用氧瓶燃烧法测定了硫酸多糖911的硫含量，根据所测硫含量确定了硫酸多糖911的平均单体式量，然后在此基础上应用脱羧法对硫酸多糖911样品的含量进行了测定。

The liver fibrotic model was induced by CCl4 i.p for 5wk. Telmisartan was given at the same time model establishment in each intervened group by administration lasted for 6wk. Decollate to get the blood of all rats after 7 weeks . ALT、AST and ALB of serum was detected by automatic biochemistry equipment. Hyaluronic acid was detected by ELISA detection. Liver and spleen was obtained to calculate the index. The liver pathological changes were observed in each group of rats after HE staining to evaluate the therapeutic effect of Telmisartan; TGF-β1、PPAR-γand PDGF of liver tissue was detected by the method of immunohistochemistry respectively; The mRNA expression of TGF-β1、MMP-1、TIMP-1、α-SMA、PPAR-γand iNOS was detected by RT-PCR detection, respectively.

腹腔注射CCl4制备SD大鼠肝纤维化动物模型，连续灌胃6周，处死动物取血，检测血清ALT、AST、ALB；ELISA法测定血清透明质酸；取肝、睥，并计算肝、脾指数，组织切片HE染色后进行组织病理学疗效评估；用SP免疫组化法测定肝组织TGF-β1、PPAR-γ及PDGF蛋白表达；半定量RT-PCR方法检测肝组织TGF-β1、MMP-1、TIMP-1、α-SMA、PPAR-γ和iNOSmRNA的表达。

Histopathological changes of lung tissue were observed under light microscope. The protein expression of MMP (MMP-2, MMP-9) and TIMP (TIMP-1) in lung tissue were determined by immunocytochemistry. RESULTS: Decompensate respiratory acidosis (pH =7.20±0.04, PaCO2 =7.84±0.15) developed in group B.

用ELISA法测定大鼠血清MMP-2、MMP-9、TIMP-1活性及NE活性；弹力纤维染色标本进行弹性纤维相对含量的测定；免疫组化方法检测肺组织中MMP-2、MMP-9及TIMP-1的表达及光镜下进行病理学观察。

The main regions (405-1 146 nt) in the glyco pro tein gene of 8202,BRV and MRV,isolated from deer,cattle and mouse in China re spectively,of rabies virus was amplified by reverse transcriptase-polymerase ch ain reaction,cloned and sequenced.

对来源于鹿、牛和鼠的狂犬病病毒野毒株82 02、BRV、MRV的G基因405～1 146位核苷酸序列进行了RT-PCR扩增、克隆和序列测定，并应用计算机软件对这3个毒株的测定序列和人源株CGX89的相应序列进行了分析比较。

Because fluid pressure and rock stress change during sealed coring process, the degasification and rock pore volume change. As a result, there is difference between laboratory measuring saturation with in-situ saturation. Therefore the laboratory measuring fluid saturation has to be corrected to predict the in-situ fluid saturation.

在密闭取心过程中，由于流体压力和岩石应力的改变，导致流体脱气和岩石孔隙度改变，因此室内测定的岩心含水饱和度和实际油藏含水饱和度存在较大的误差，有必要将室内测定的含水饱和度校正到油藏条件下。

Methods: The amplitudes and the delitescence of OPs of flash electroretinogram in 75 type 2 diabetic patients with cataract were measured before cataract extraction and implantation of artificial lens, then postoperative ocular fudus and vision were examined, the relationship between them were analysed, and all were compared to the group of normal control.

选择75例2型糖尿病白内障患者，在白内障囊外摘除人工晶体植入术前行闪光视网膜电图振荡电位总波振幅及其子波的波幅和潜伏期测定，术后行眼底检查、矫正视力测定，比较患者术前OPs各子波振幅、潜伏期、OPs总波振幅与术后眼底所见、视力恢复之间的关系，并与对照组比较。

As such, it rejects not only radiometric and isochron dating of the age of the Earth, arguing that they are based on debatable assumptions, but also approaches such as ice core dating and dendrochronology, which make the barest of assumptions of uniformitarianism, and which hint that the Earth is far older than the Ussher-Lightfoot Calendar suggests.

如同这个，不仅拒绝放射性和等时线地球年代测定方法，争论基于可争论的假定，而且采用这类冰核和树木年代学测定，树木年代学使得均变论假定一览无遗和暗示了地球比Ussher-Lightfoot日历更为古老。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
