But there are also some limitations when applying traditional fault tree analyzing method to certain systems that are amendable, complex, time consuming and with random failures that occurs randomly.

但是由于其局限性，对于具有可修复、系统复杂、昼夜连续运行、动态随机性故障发生的系统而言，传统故障树分析方法便显得"力不从心"。

In this paper, the theory and approach of differential geometry are employed systematieally and the analytic expression of the nonlinear excitation eonrtol stratege is worked out.

由于电力系统强非线性的影响，当系统状态发生较大变化时，这些控制器的效果都难以令人满意。

A nonlinear on-line approximator is utilized to estimate uncertain parts in the system, simultaneously, to monitor the faults and estimate the fault value.

非线性在线估计器用于估计系统不确定部分，同时监视系统是否发生故障，估计故障的大小。

So it is very important for oblige to ascertain whether the copyright is reversible or not in the contract.

事物在一个变化的过程中，不但物质系统的本身发生了变化，而且系统的外界环境也会相应的变化。

Choosing time delay as the control parameter, the stability of trivial equilibrium is discussed by analyzing distribution of the roots of the associated characteristic equation. It is found that Hopf bifurcation occurs from trivial equilibrium when the delay passes through critical values, then the critical values and their relations with system control parameters are obtained.

以时滞量为参数，通过分析对应线性系统特征方程的根的分布，讨论了平凡解的稳定性，得到了平凡解发生Hopf分岔而失稳的临界时滞量以及临界时滞量与系统控制参数的关系。

At last the suggestion of pay more attention to the relationship of mineral nutrients and pests and diseases control in intercropping system in future study was advanced.

同时阐述了矿质营养与病虫害发生的关系，并针对目前间套作系统中养分与病虫害关系研究的空白，提出今后的研究应加强间作系统中养分与病虫害控制方面的研究。

By analysing the hidden dangers of gas-fired boiler room in system of burning,leak of gas and system of steam-water,the paper presents some safety measures considered during designing of blast shelter,gas pipeline,aeration and fire controlling of boiler room,and advanced some prevention measures to realize the safety run.

从燃烧系统、燃气泄漏、汽—水系统三方面分析燃气锅炉房的安全隐患，提出工程设计时在抗爆卸压、燃气管道及通风与消防等方面应考虑的安全措施，并提出了预防锅炉房事故发生的值得注意的问

The existence of fault resistance may add an additional reactive or capacitive component to the impedance seen by the protection.

在双电源系统中，由于对侧系统助增电流的影响，保护测量到的阻抗会偏离故障线路的实际值，从而引起距离保护发生超越或缩短保护距离。

Results show that existence from strong convergence of water vapor and the conditional convective instability in the middle and low troposphere probably provided the suitable environment for heavy rainfall.

分析表明，对流层中低层水汽的大量集中以及对流不稳定条件的存在可能对此类系统发展提供了有利环境，对其启动的机制作了初步的讨论，认为地形的动力强迫和地面冷锋以及低空急流扰动可能对此类系统的发生发展起了触发作用。

According to complex system theory, power systems in self-organized criticality state have high probability of occurring of cascading failures.

根据复杂系统理论，电力系统在自组织临界状态下发生连锁故障的概率将会大大提高。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
