The result is important from both theoretical and engineering viewpoints because of its generality and constructiveness, so that from it we can chose many kinds of decoupling control law which can meet many other requirements such as stability and robustness for the closed-loop system.

此结果之所以在理论上，特别在工程上是重要的，在于它的构造性和一般性，因为它可扩大解耦控制律的选择范围，可使闭环系统在解耦的同时，更容易找到满足其它一些要求的解耦控制律，如稳定性、鲁棒性等。

The construction enterprises of all completed construction projects to be itemized and in the investigation of the existence of peasant workers wages owed projects to be closed immediately; At the same time we must establish internal labor workers in the enterprise dedicated reserve system as contingency funds, devoted to the settlement of arrears of wages and the workers have unexpected events.

各建筑业企业对所有已竣工和在建工程要进行逐项排查，对存在拖欠农民工工资的工程项目，要立即予以结清；同时要在企业内部建立劳务用工专用储备金制度，作为应急资金，专门用于解决因拖欠民工工资而产生的突发事件。

High accurate double channels rotary transformer is the position detecter of the launcher, feeding back the position information of the closed-loop control system.

采用高精度双通道旋转变压器作为发射架的位置检测装置，实现了闭环控制系统中位置信息的反馈。

Both controllers consist of linear output feedback and nonlinear feedback, resulting in a closed-loop system with asymptotic stability in the invariant set inside the domain of attraction.

控制器由线性输出反馈项和非线性反馈项组成，使得闭环系统在包含于吸引域的不变集内渐近稳定。

In chapter 3, based on the work of chapter 2, we firstly investigate the effect of the spontaneously generated coherence on gain of lasing without inversion in a closed three-levelΛ-type atomic system with Doppler broadening.

这些结论是与以前关于封闭Λ型系统中Doppler展宽对LWI增益影响的研究结果即增益(或强度随Doppler展宽值的增加而单调减小大不相同的。

In chapter 4, for the first time, we studied the control role of the relative phase between the probe and driving fields on inversionless gain of the probe field in a closed and Doppler broadeningΛ-type three-level system with the spontaneously generated coherence.

结果发现：(1)不管探测场和驱动场是同向传播还是反向传播，驱动场是失谐还是共振，无反转增益总是随相对位相的改变而作周期性变化，周期为2π。

By using the numerical calculation results of the density matrix equations of motion of a closed Λ-type inversionless lasing system, the effects of the propagation of light fields on the gain of lasing without inversion, Rabi frequencies of the probe and driving fields, and the modulation role of spontaneously generated coherence on the effects were investigated when the Doppler broadening presents.

利用封闭Λ型三能级无粒子数反转激光系统密度矩阵运动方程的数值解，研究了存在Doppler展宽的情况下光场的传播对LWI增益、探测场和驱动场Rabi频率产生的影响以及有自发辐射诱导相干对这个影响的调制作用。

Application of the double closed loop control has already been popular in SMPS, because such a system has a fast dynamic response and good stability.

双闭环控制在开关电源中的应用非常普遍，是因为它使系统具有较好的动态性和稳定性。

In this paper, the nonexistence of the closed orbit which circles the equilibrium is proved by using the Dulac function, then all the orbits of the system are bounded by the Filippov transformation and comparability theorem.

本文利用Dulac函数法，首先判定了不存在绕平衡点的闭轨线，然后利用Filippov变换和比较定理，证明了系统所有轨线的有界性，进而得到了平衡点是全局渐近稳定的。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
