At many occasions they arise quite natu-rally.For example,they appear in the Iwasawa decomposition of the isometry group ofa non-compact Riemannian symmetric space.Also,every connected homogeneous Rie-mannian manifold of non-positive sectional curvature can be represented as a connectedsolvable Lie group with a left-invariant Riemannian metric.

它们出现在非紧致黎曼对称空间的等距群的Iwasawa分解中；任一非正截面曲率的连通齐性和黎曼流形可以表为带有左不变黎曼度量的连通可解李群等，带有左不变黎曼度量的幂零及可解李群的微分几何，调和分析和谱几何是重要的研究课题。

In plants , NO has recently been demonstrated to be involved in the regulation of growth and development in the response to abiotic and biotic stresses and it is a key signal messenger in disease resistance in plants. More important , it has been found that NOs function in plant is similar to the traditional phytohormone , so it is forecasted to be a new type of hormone in plant.

近年来的研究发现，它不仅在血管松弛、神经传导以及先天性免疫反应等动物生理代谢过程中是一种关键的第二信使，而且在植物中也起着非常重要的作用，是植物生长和发育的调节分子，能够对生物性和非生物性的胁迫作出反应，并且在植物体的抗病防御反应中也是一种重要的信号物质；更重要的是，近年来发现NO与各种植物激素的功能都有着重叠，因此有人预测NO可能是植物体内的一种新型激素。

Though theories and methods about noncommutative problems mainly root in quantum field theory, discussing noncommutative effects on resolvable model based on quantum mechanics is important similarly.

尽管研究非对易空间问题的理论和方法主要来自于量子场论，然而，在量子力学的框架下研究一些可解模型的非对易空间效应也是非常重要的工作。

Comparative analysis with the other non-stochastic model constrained by facies shows that the stochastic waterflooding model constrained by facies is consistent with the flooding conditions and rules, it also consistent with the rules of reservoir development and aeolotropism distribution, the result is more reliable, which can provide the effective foundation to adjust and tap the potential for this area.

与非相控随机建模方法预测的模型对比分析表明，相控下的随机水淹模型比较符合油田开发过程中的水淹状况及规律，符合储层发育及其非均质性分布规律，可信度高，为该区调整挖潜提供了重要的地质依据。

The bad environment is a very important nonbiological force factor influencing agricultural production and ecological environment.

不良环境是影响农业生产和生态环境的非常重要的非生物胁迫因素，在各种非生物胁迫中，低温对植物的影响最为突出。

The bad environment is avery important nonbiological force factor influencing agricultural production and ecological environment.

不良环境是影响农业生产和生态环境的非常重要的非生物胁迫因素，在各种非生物胁迫中，低温对植物的影响最为突出。

Practically, there are unsteady flow in the water diversion system of the pumping station as a result of the change of upsteam stage and pump operation stage. It has important significance for the optimum operation and management of the pumping station to study on one-dimensional unsteady flow of water diversion system of the pumping station.

同时在泵站实际运行过程中，由于上游水源水位和泵站运行水位变化的影响，引水系统内往往会产生非恒定流，因此，泵站引水系统非恒定流计算研究对泵站的优化运行和管理具有重要的理论意义和实际应用价值。

You were not uncomfortable being a small infant who offered no action or words, for you remembered the Well-Being of the Universe; you remembered your intentions in coming forth into your physical body, and you knew that there would be plenty of time for acclimating to the language and ways of your new environment; and, most of all, you knew that even though you would not be able to translate your vast knowledge from your Non-Physical environment directly into physical words and descriptions, it would not matter, for the most important things to set you on a path of joyful creation were already emphatically in place: You knew that the Law of Attraction was consistently present and that your Guidance System was immediately active.

作为一个不能言语，不能行动的婴儿，你并不觉得不舒服-因为，你记得宇宙的福祉，你记得来到这个肉体时保持的意图，你也知道将会有大把的时间来熟悉你的新环境的语言和方式，并且，最为重要的是，你知道尽管还不能把你来自非物质环境的大量知识翻译成有形的言语和描叙，这并不重要，因为把你置身于开心创造之路的最重要的东西已经就位了：你知道吸引力定律总是不变，而你的引导系统也立马激活了。

Ascorbate acts as an important antioxidant in both enzymatic and non-enzymatic reactions in plant cells.

抗坏血酸作为一种重要的抗氧化剂，在植物细胞的酶促和非酶促反应中都具有重要意义。

Open-phase operation in large power unit is very harmful to generator and theoperation of power system. The study on open-phase operation and the analyses ofextracted fault information are of great value to the safety of generator and the operationof power system.

发电机组非全相运行的分析与研究，以及非全相故障信息的提取与判断，对于保护发电机组与系统的运行安全有着非常重要的研究价值。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
