At first, based on the results of the field tests and studies, this paper indicates that there are two kinds of low frequency power oscillations on the weak tie line: one is caused by negative damping, and belongs to the free oscillation; the other is caused by periodic load disturbances and periodic adjustments, and belongs to the forced oscillation.

首先，本文根据现场试验和研究结果指出，互联系统的弱联络线上存在两类性质不同的低频功率振荡：一类是由负阻尼引起的，属于自由振荡；另一类是由于系统周期性负荷扰动或振荡调节等引起的，属于强迫振荡。

First attempts confirmed the rightness of this idea, but at the same time also the practical inaptness of such grid lenses because of the too-strong absorption of the electron beam at the four grids and due to the field distribution by the wires.

正是由于这中理解上的失误，Ruska才误打误撞的去研究磁透镜了，而后来磁透镜以更稳定的性质和灵活性盖了静电透镜的帽，这也是冥冥之中自有天意吧。

There are many difficulties in implementing farmers' rights for two reasons. One is the benefit divarecation between developed countries and developing countries .The other is the infantility of farmers' rights theory.

我们有必要解答农民权的一些基本理论问题：首先，本文认为农民权不应被看作一种政治或道义上的抽象权利，而应被视为一种知识产权性质的排他的财产权利。

Chapter 3 is devoted to equistability and equiboundedness of matrix differential equations by making use of the symbol property of the matrix Liapunov function and its Dini derivate on specific set.

第三章研究了矩阵微分方程的渐近行为，给出了直接运用矩阵Liapunov函数在某特定集合上的符号与其广义Dini导数符号的性质研究矩阵微分方程的稳定性和有界性。

Theodore's Christology, although it contributed to Nestorianism, anticipated the formula adopted at the Council of Chalcedon (451) on the dual but united natures of Christ.

西奥多的christology ，虽然它有助于景教，预计公式通过在安理会的迦克墩（ 451 ）上的双重性质，但美国的基督。

In order todiscuss the structure of operator algebra, in recent years, many scholars have focusedon linear maps and various multiplieative maps on opcrator algebras, and studied thealgebraic and geomrtrial properties and the problem of classification of these mapsMany deep and intercepting results have been achieved, and many new ideals and meanswas introduced.

为了进一步探讨算子代数的结构，近年来国内外许多学者对算子代数上的线性映射和各种可乘映射进行了系统研究，探讨这些映射的代数和几何性质以及刻画分类问题，取得丰富成果并不断提出新的思路和方法。

In the first part of this paper, we give some basic concepts of regular Sturm-Liouville problems and some Sturm-Liouville problems with eigenparameter in the boundary conditions and the definition and properties of the Krein space. Using the Krein space, we describe a class of Sturm-Liouville problems with eigenparameter in two boundary conditions and prove that it can generate a self-adjoint operator in Krein space with only point spectrum.

第一部分我们介绍了一些基本概念如正则Sturm-Liouville问题、边界条件含参数的问题、Krein空间等，并利用Krein空间的定义和性质描述了一类参数边界条件的Sturm-Liouville问题，证明它可构造一Krein空间上的自伴算子，并且谱全为点谱。

The experiment should be such as to yield fruitful results for the good of society, unprocurable by other methods or means of study, and not random and unnecessary in nature.

实验应该收到对社会有利的富有成效的结果，用其他研究方法或手段是无法达到的，在性质上不是轻率和不必要的。

However, it is difficult for the quartz substrate to scale-down by photolithography. In this article, we develop another type of piezoelectric material, PbZrxTi(1-x)O3, as a thin film by sol-gel route to replace the quartz crystal as a resonator. The novel hydrothermal annealing with microwave system is proposed to substitute the conventional furnace annealing.

本研究则是用同样具有压电性质的材料锆钛酸铅(PbZrxTi1-xO3)，以溶胶－凝胶法制成压电薄膜，来取代传统的石英晶体；再以微波反应系统进行水热式退火，来取代传统高温制程上的热处理方式，同时根据实验结果，进一步推论水热式退火的反应机制。

And then, by regarding the curve and surface as a map from differential manifold to topological manifold, we present the framework of GRPCS and discussed its basic properties in detail. GRPCS provides a unified framework for parametric curve and surface.

然后通过势函数来构造微分流形上的单位分解，将曲线曲面看作微分流形到拓扑流形的映射，给出了广义有理参数曲线曲面的整体理论框架，并对广义有理参数曲线曲面的基本性质进行了讨论。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.

同时，论述了一体化管理体系构建中的几个主要问题，包括职业健康安全管理中的危险源辨识、风险评价和风险控制、顾客满意度的科学监测、法律、法规体系的完善、一体化管理体系与企业标准化体系的有机结合、统一的领导机构和工作机构、一体化的内部审核和管理评审。
