At the same time, mature sheath still have the capacity of Cl~--exclusion.2 Alleviative effect of exogenous substance under salt stressThe salt tolerance of plant is a integrative mechanism, its fit to salt stress was multifarious, the salt tolerance of crop is a kind of complicated physiological mechanism that is the acted together result of genetic characteristic and exoteric condition, the alleviative effect on salt stress caused by exogenous substance was realize through different approach, so it is very difficult to explain the relation of exogenous substance and salt tolerance with a given index.

成熟叶叶鞘同时还具有拒Cl~-能力。2外源物质对盐胁迫的缓解作用植物的耐盐性是一种综合机制，其对盐胁迫的适应也是多种多样的，作物的耐盐性是一种相当复杂的生理功能，是遗传特性与外界环境共同作用的结果，不同的外源物质对盐胁迫的缓解作用是通过不同途径实现的，因而很难用某一个指标来说明外源物质与耐盐性的关系。

Based on the petrological and geochronological study of metamorphic complexes from the Grove Mountains, the following conclusions are reached.(1)Exsolution texture is widely found in clinopyroxene in mafic granulites. A peak metamorphic temperature of 850 C was obtained from the reintegrated compositions of exsolved clinopyroxene. The preservation of augite megacrysts suggests a single episode of high-grade metamorphism for the Grove Mountains.(2)The compositional comparison of garnet from pegmatites with that from country rocks demonstrates that garnet in pegmatites is of xenocryst origin, and late amphibolite facies metamorphism does not occur in this area.(3)The Pan-African charnockite and post-tectonic sheet-like granite were first recognized in East Antarctica. Their occurrences suggest a collisional orogeny during the Pan-African time.(4)The SHRIMP U-Pb zircon dating on various rock types indicates that the major metamorphism in the Grove Mountains occurs at c. 550 Ma, and the tectonothermal evolution terminated at c. 500 Ma. The Grenvillian granulite facies metamorphism did not develop in the studied area.(5)The Prydz belt, the second Pan-African suture within the Gondwana suppercontinent, was further comfirmed based on this study. The Gondwana suppercontinent was not formed by the simply juxtaposition of East and West Gondwana, but by the collision of several blocks during the Pan-African time.

本项目通过格罗夫山地区高级变质杂岩的变质岩石学和同位素年代学研究，获得如下重要认识：（1）发现辉石出溶结构，由此获得峰期变质温度为850 C，并根据火成普通辉石的识别确定该区只存在单相麻粒岩相变质；（2）通过伟晶岩中石榴石斑晶与围岩中石榴石的对比研究提出了石榴石的捕虏晶成因，进而确定该区不存在晚期角闪岩相变质作用；（3）在东南极首次识别出泛非期紫苏花岗岩和后构造层状花岗岩，为泛非构造热事件的碰撞造山成因提供了重要佐证；（4）对不同岩石类型的锆石SHRIMP定年精确地限定了格罗夫山地区主期变质作用发生于泛非期，～550 Ma，热事件结束于～500 Ma，年代学数据没有揭示在该区存在格林威尔期麻粒岩相变质作用的迹象；（5）进一步确认了东南极内部普里兹带的存在，它属于冈瓦纳超大陆内部的第二条泛非期缝合带，据此认为冈瓦纳超大陆并不是由东、西冈瓦纳陆块的简单拼合而成，而是多个不同块体拼合的结果。

Results showed that L-THP possessed negative inotropic and negative chronotropic action, lowed left ventricular pressure and it's infinitesimal calculus, decreased heart output in per min., shorten 〓 and 〓 of action potential of ventricular papillary muscle of guinea pig and even the plate-phase of action potential disappeared in larger dose group , but prolonged 〓. we studied transmembrane transportation of 〓 after administering L-THP , L-THP not only depressed uptake and increased release of Ca 2+ in normal myocardium, but also it showed stronger inhibition in cell injured by ISO, and fully eliminated the effect of ISO increasing uptake and decreasing release of 〓. By detecting the 〓 content of ventricular single myocyte using fluorescent probe Fluo-3/AM, results correspond to that done above, L-THP decreased 〓 content inside of cell significantly. Using whole-cell mode, we observed the effect of L-THP on Ica in ventricular single cell, it was found that L-THP decreased Ica, the effect increased with increasing it's dose, and had voltage, frequency-dependency. Dose highly corelated to effect, corelative constant is 0.87. When washing cell with normal tyre's solution, Ica could recover, which proved the blocked action of L-THP on calcium channel once again. Meanwhile, L-THP reduced production of MDA in heart injured by ISO in dose-dependent manner, improved content of GSH-Px, in case tissue or cell free from free radical damage.

结果显示，该药物具有负性肌力和负性频率作用，降低左室压及其微分，终使每分心输出量减少；缩短豚鼠心室乳头肌动作电位时程的〓和APD〓，大剂量使动作电位平台消失，〓延长；同位素示踪法研究证实L-THP抑制〓摄取，促进〓释放，降低细胞内的〓含量；单通道水平的研究证实，L-THP减少豚鼠心室肌单细胞内向钙电流，且具有剂量，电压，频率依赖性，其作用易于洗脱，药物剂量与Ica也具有高度相关性（相关系数r为-0.87）；L-THP还可抑制ISO损伤心肌组织所致的丙二醛含量增加，增加谷胱甘肽过氧化物酶的量，使组织细胞免受损伤。L-THP阻断L-型〓通道，抑制〓的摄取，促进〓的释放，降低细胞内〓含量L-THP作用的离子基础。

Besides, the reduction of the dispersion part of potential leads to a lower critical temperature and higher in-plane part of molecular dipole moment; however, because the reduced critical temperature is relatively small compared with that of a 3D system, disappearance of the critical point has not been observed in the quasi-2D SM system within practical scope of the simulation.

尽管受到插入困难的限制，本文没有直接发现随着色散作用的减小汽液共存消失的现象，但根据对模拟结果的分析及对偶极作用的讨论，本文猜测这种情况在更小的色散作用和更低的温度下仍然是会发生的。

Last through the equation analysis to philosophical plane, we found: This article does not negate the particles in the second, instead of a degree in physics in promoting the development of the basic conceptual material, spin with isospin,the two factor are the fundamental properties, quality and charges in a certain sense, there is a relationship.

最后通过这一关系式的分析，上升至哲学层面，我们发现：这篇文章并没有否定实物粒子的波粒二象性，反而一定程度上推动了物理学在物质基本概念上的发展，二旋性才是物质的根本属性，质量和电荷在一定意义上是有关系的，引力作用和电磁作用同属一种作用的不同侧面。

Which play a major role in the pathological changes of restenosis after angioplasty But AT2 receptor is only expressed abundantly in the fetal vasculature with rapid decline after birth and the level of re-expression in the adult vasculature after injury is very low So there are little understanding about the actions of AT2 receptor in vascular diseases, especially in the restenosis after injury.

在寻致或加重VSMC增殖和迁移诸多因素中，血管紧张素Ⅱ所介导的生物学作用是其中重要的因素之一。AngⅡ具有多种生物学作用，其作用的多样性是通过其受体的多样性介导的，目前已确定的AngⅡ受体至少有两型，即AngⅡ 1型受体(AT1R)和AngⅡ 2型受体(AT2R)。

Tail fish there is some balance, and so on, birds covered with short hair, such as horse and cattle dogs, and so on The animal's tail fly out of there, and the tail is not the role of animals such as humans, flies, bees, ants, and other small animals in particular, sperm and there is a tadpole's tail!

Japonicus.Nerve extraction substance of sea star and dithiothreitol has been reported to be effectively to induce oocyte maturation in sea cucumbers. In this study we tested their effects on oocyte maturation induction in sea cucumber A. japonicus. The results are as follows, oocyte of A. japonicus does not get mature spontaneously. Neither NES alone nor NES with follicle suspension can induce oocyte maturation. While DTT can prominently increase the percentages of germinal vesicle break down. When the concentration of DTT is between10-1 mol/L and 10-3 mol/L, the effect of maturation induction is more sufficient. When the concentration is about 10-2 mol/L, the percentage of GVBD can reach up to more than 90%.

分别利用在海参中有诱导作用的海星神经提取液和二硫苏糖醇对从成熟卵巢解剖出的刺参卵母细胞进行诱导成熟试验，结果显示，刺参的卵母细胞在海水中不会发生自发成熟，海星神经提取液以及神经提取液加滤泡悬浮液对卵母细胞没有诱导成熟的作用，而二硫苏糖醇处理可以诱导卵母细胞生发泡破裂，当DTT溶液的浓度处于10-1 mol/L到10-3 mol/L之间时，对刺参卵母细胞的促熟作用较为明显，在10-2 mol/L左右时，卵母细胞的诱导成熟率可以达到90%以上。
