Language is the use of certain language environment can be completed. Communication is inseparable from the conduct of the activities of the main -- and can not be separated from communication on the time, place, subject, purpose, Situational factors such occasions and without specific socio-cultural atmosphere.

语言的运用是在一定的语言环境中才能完成的，语言交际离不开进行这一活动的主体——人，离不开交际的时间、地点、话题、目的、场合等情景因素，也离不开具体的社会文化氛围。

The influence factors of mechanical properties of the ionomers, the compatibilization of the ionomer for SBS/ chlorohydrin rubber blend and the effect of mass ratio on properties of ionomer/polypropylene blends were investigated.

研究了离聚体力学性能的影响因素、离聚体对SBS/氯醇橡胶的增容作用、质量比对离聚体/聚丙烯共混物性能的影响。

The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.

离心浮升力是造成非等温轴向通流旋转盘腔内流动不稳定的主要因素，而哥氏力的存在加剧了流动不稳定性，导致流场失稳提前发生，而且在哥氏力的作用下流线发生偏转，盘腔内r-θ面出现了旋向相反的对涡，流动结构更加复杂化；随离心浮升力的继续增加，r-θ面的对涡减少，当其超过某一临界值后部分冷流体侵入盘腔，对涡减少至一对，而且沿径向充满整个盘腔；此后随离心浮升力的增加对涡的数量不再变化；r-θ面的对涡相对于盘面周向移动，但是形状基本保持不变。

This dissertation is concerned with the kinetics of the nonequilibrium dissociation and ionization of gases that are significant in the high temperature gas dynamics. There are two parts in the dissertation. In the first part, the kinetics of dissociating gas, a theoretical calculation is made of the nonequilibrium dissociation of the diatomic molecule behind a strong shock wave front.

On the basis of this system andpreviously morphological, physiological and biochemical studies on cucumber in vitrogynogenesis. Materials from both typical gynogenesis using M99 as induction medium andnon gynogenesis using W5 as induction medium were collected. The activities anddistribution of peroxidase and its isoenzymes, content of soluble protein and distribution of allprotein during early stage of cucumber in vitro gynogenesis and non gynogenesis wereinvestigated by biochemistry and histochemistry technology.

本试验在前期有关离体黄瓜雌核发育形态学和生理生化研究的基础上，以诱导离体雌核发育的 M99 培养基上和非雌核发育的 W5 培养基上培养的黄瓜未受精子房为试材，采用生物化学技术和组织化学技术，深入研究了离体雌核发育早期外植体内的标志酶——过氧化物酶及其同工酶的活性及分布的变化、可溶性蛋白质的含量和总蛋白质分布的变化及核酸和多糖分布的变化，为揭示离体雌核发育早期的细胞分化机制提供科学依据。

In our study, the increased HR indicate that the parasympathetic nerve system was predominant in vivo or the intracardiac sympathetic nerve enhanced its modulation in vitro.After treatment of Atr, the isolated heart was only controlled by the intracardiac sympathetic nerve.

如果离体前后交感和副交感神经支配心脏的程度相同，HR不应发生明显变化，本实验中离体后HR增加，表明离体前副交感神经系统占优势或者离体后心内交感神经功能亢进。

From the perfusion experiments with isolated rabbit heart and vessels were obtained the follow- ing results:(1)Potassium antimony tartrate produced depression of the isolated rabbit heart,and this depressant action became more marked when the pH of the solution was raised from the original value of 5.4 to that of 7.2;(2)At the same pH levels,the cardiac action of the potassium salt was slightly stronger than that of the corresponding sodium salt;(3)The slight vase-dilator effect of potass- ium anti...

从离体器官的灌注实验得到下列结果：(1)酒石酸锑钾对离体兎心有抑制作用，将其pH 从5.4调整到7.2时，作用亦随以增加。(2)在相同 pH 时，酒石酸锑钾的心臓抑制作用较酒石酸锑钠略强。(3)酒石酸锑钾对离体兎耳血管的轻微扩张作用，系由于该药溶液的微酸性反应，当将药液 pH 调整至7后即无作用。(4)对于离体兎肺血管则不问 pH 为4.8或7，均产生轻微的血管收缩作用。

The Fourth part analyzed the necessity and conditional foundation of offshore financial market, combined abroad experience of development of offshore financial market, such as choosing mode which suit oneself etc. This part also analyzed the present condition of Chinese offshore financial market and problem which appeared during the development of Chinese offshore financial market.

第四部分在分析了中国建立离岸金融市场的必要性和条件的基础上，结合国外发展离岸金融市场的经验如选择适合自身的模式等，分析了中国离岸金融市场的现状，剖析了中国离岸金融市场在发展过程中出现的问题。

Studies show that the AM method and the new analytical expression are reliable and economical physical methods for studying full vibrational energy spectra and molecular dissociation energies of diatomic electronic systems theoretically, which are particularly useful for those diatomic systems whose high-lying vibrational energies may not be available.

A new method for a utomatically adjusting the spindle velocity is proposed in the paper. The method juges the extreme point of out-of-focus signal and calculates the time intervals between the adjacent extreme points by means of the characteristics of out-of -focus signal, and finally estimates the band of the out-of-focus signal.
