For compact hypersurfaces and highcodimension compact submanifolds initial data respectively, we prove that the flow hasa smooth solution for all time under almost optimal conditions. Those conditions arethat the second fundamental form on the initial submanifolds is not too large, the exter-nal force field, with its any order derivatives, is bounded, and the field is convex with itseigenvalues satisfying a pinch inequality.

我们分别对紧超曲面初值和高余维紧子流形初值证明了当初始曲率比较小，并且外力场除了要各阶导数一致有界外，还要满足凸性条件以及特征值的一个pinch条件时，这种热流的光滑解长时间存在。

By using the a device being similar to water segregator and by controlling the temperature, cyclization of the intermediate product in chloroform reduced carbonization and gave 2-dodecaneanthraquinane in 68.1% yielding.

以十二烷基苯和苯酐为起始原料，经酰基化、关环和磺化三步反应合成了3-十二烷基蒽醌磺酸；并进一步改进和优化了合成工艺条件：即在催化剂三氯化铝过量50%并有三乙胺存在的条件下，中间体2-（4-十二烷基苯甲酰基）苯甲酸收率为72.45%；关环反应采用氯仿作溶剂，利用类似分水器的装置有效控制反应温度以减少碳化，2-十二烷基蒽醌的收率为68.1%。

Characteristic parameters of coal spontaneous combustion were qualitatively studied and quantitatively determined by coal self-ignition experiment from two aspects: coal oxidation and exothermic which is produced by oxidation.

在井下现场应用研究方面，按照安全规程的要求和采空区瓦斯运移规律结合对实际条件下的漏风规律研究存在发火条件的危险区域，通过实验研究，对指标气体产生和发展规律有了充分认识，有效地指导防火灭火工作。

Through to pumps with the mechanical seal practical application and the theoretical analysis, proposed the mechanical seal actual seal effect not only with the mechanical seal own performance related, the condition which with other spare parts also which provides the condition as well as the seal servosystem provides to have the important relations, therefore pumps the unit product when the design, must for the mechanical seal use provide a good external condition.

通过对泵的机械密封实际应用和理论分析，提出了机械密封的实际密封效果不仅与机械密封本身的业绩有关的条件与其他零件也提供了条件以及印章伺服系统提供有重要关系，因此，泵的单位产品的设计时，必须对机械密封使用提供了一个良好的外部

It may because of no considering of the effects of blood flow shear stress.

静态条件下联合培养的内皮细胞的形态及功能特性与在体条件下均有差异，这可能是没有血流切应力对内皮细胞直接作用的结果。

The results showed that the influence of wood species on electromagnetic shielding properties was obvious and regular.

结果表明，在处理条件和化学镀条件相同的情况下，树种的影响很明显并有一定的规律性。

Note: this condition is checked before any other condition,side effects.

注意：在检查时，这个条件比其它所有条件都先被检查，包括会有副作用的keep-state或者check-state。

The results of MTT method In vitro culture renal tubular cells showed that the proliferous activity changed from sightly to dramatically intensed in response to fluoride concentration from 0.1mg/L to 15mg/L, but renal tubular cells proliferation obviously decreased in the 25mg F-/L group.

利用生物化学方法检测氧化应激指标，结果表明在钙营养充分的条件下，投氟100mg/L 16周大鼠肾组织GPX活性不是下降而是明显提高，脂质过氧化物变化不明显；低钙饲养条件下投氟100mg/L 16周大鼠抗氧化酶SOD活性亦有明显升高，而GPX却呈降低趋势。

According to the relevant datums and field investigations, the paper makes No. 316 national highway in South region as research region to analyze the conditions of inoculating disasters and slope s transform destruction model and draws such conclusions:(1)Many factors such as terrain, geomorphic, lithosome and solum character, geologic structure, neotectonic movement, rainfall condition, groundwater trait, anthropokinetic and so on influence on the study region, which make the geological disasters occurred frequently and generate enormous hazards.(2)The geological disasters have such distribution characteristics: terrain and tectonic make geological disasters development of osculating correlated property, relative concentrate property, packet property, periodic property and so on.

本文首先在搜集相关资料和野外调查的基础上，以陕南316国道公路为重点研究区，全面分析了研究区域内地质灾害的孕灾条件与斜坡变形破坏模式，得到了以下认识：(1)研究路段地质灾害的发生发展主要受控于区内地形地貌、岩土体特性、地质构造与新构造运动、降雨条件、地下水特征及人类工程活动等因素：(2)研究路段发育滑坡、崩塌、泥石流和危险斜坡等四种地质灾害，具有如下的分布特征：地势与构造对地质灾害发育的密切相关性、相对集中性、群发性、周期性等；(3)研究路段斜坡地质灾害主要有六种变形破坏模式分别为：顺层滑动破坏、蠕滑—拉裂变形破坏、弯曲—拉裂—剪断破坏、旋转式滑移—拉裂破坏、楔形体滑动破坏、堆积层沿基岩面的滑动破坏模式，而且斜坡灾害的变形破坏往往是多种模式的组合。

If the neighborhood of equation solution is solvable and meets the point- by-point Lipschitz condition, stable boundary could be obtained as the convergence of the difference method is realized, and thus the stability is ensured.

方程解的邻近如果可解并具备逐点Lipschitz条件，则差分法收敛必有稳定界存在，从而差分格式收敛性保证其稳定性，因此可以放弃线性这一重要条件。
