Experimental results, which are consonant with computer simulation, supply support to engineering.

本文在利用PVDF压电薄膜解决实际工作中关键测试问题的同时，也讨论了PVDF测试技术在冲击或强动载荷环境中所存在的局限性，并提出了相应的改进措施。

These three are mutually containable, conditionaland with each other for result.

人的实践活动本质不仅创造了人，使人成为主体性的存在，而且是对人的社会存在和社会本质的确证，同时决定了人的发展的过程性、可塑性和永远不能完成性；人的关系本质制约着人的实践活动和人的需要，决定了人必须在社会中生存和发展，是认识人并把人与人区别开来以及理解人的问题在本质上是社会问题的关键所在；人的需要本质是人从事实践活动的根本动因，从而也是社会发展的本源性动因，人的需要本质要求任何一个社会的政治、经济、文化制度、法律、政策、意识形态以及人们参与社会的种种政治、经济、文化等活动都应以满足人的需要为根本出发点和归宿。

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。

By using the theories and methods of impulsive,discrete and continuous dynamical system,arithmetic operators,optimiza-tion and numerical simulation,we study locally and globally asymptotieal stability of the boundary periodic solutions,and the permanence of the these systems.

以脉冲动力系统理论为基础，同时结合离散动力系统、连续动力系统、算子理论、优化理论等相关的理论和方法，在已有的研究成果的基础上，研究这些模型的边界周期解的局部和全局渐进稳定性、系统的持续生存、周期解的存在性与唯一性以及周期解的轨道稳定性等等。

In this paper,four aspects of the above problems were studied:Firstly, the problem of solving continuous linear operator equation inseparable Hilbert space is studied .

通过把第一类连续不适定算子方程转换为等价的无穷维方程组，然后利用投影法，给出了解存在唯一的充要条件；给出了连续线性不适定算子方程解析解，解决了不适定情况下解的表示问题，由此给出了算子方程的数值求解公式；进一步证明了，在解不唯一情况下，此表达式给出的解为算子方程的最小范数解，同时表示出了连续线性不适定算子方程的解集。

The discrete element method and the finite element method have their own advantages and weaknesses. Basically, the DEM was developed for predicting the failure problems accompanying with the transition from continuum to non-continuum media. However, it is not accurate to calculate the problem of continuum media. The FEM may forecast the failure area of the material reasonably, while it is hard to calculate the failure process in brittle media. Therefore it becomes a good choice to combine the two methods to construct a hybrid model.

离散元法和有限元法等数值计算方法各有其优势，同时也都存在不足之处：离散元法适于处理由连续介质向非连续介质转化的破坏问题，但对于连续体计算结果精度不高；有限元法适于预测材料破坏的区域，但难以直接用于计算脆性材料破坏过程，因此将两种方法结合可以形成一种较好的混合模型。

Rather contradictorily, there have large amounts of uncertainty and redundancies alongside renewed optimism and some hiring.

颇为矛盾的是，於存在大量不确定性和裁员的同时，却又有重拾的乐观态度和人员招聘的出现。

Regional development strategy of the state can lead to regional disparities expanding, and also can be as an external condition for underdeveloped region to achieve convergence;resources of western region can cause influence to regional development, but it is limited, and function with other conditions as premise, such as environmental abilities, technologies etc. Even to some degree, western region fell into present environmental poverty just owing to abundant resources.

在外部条件中，国家的区域发展战略可以导致地区差距的扩大，同时也可以作为实现区域趋同的外部条件而存在；而西部地区的资源禀赋对西部地区的发展产生的影响是有限的，并且作用是有条件的，甚至在大程度上正是由于资源的丰富而导致了西部地区目前的环境贫困。

In addition, through the regression analysis using the panel data of 9 cities in Pearl River Delta, we conclude that there exist σ-convergence and β-convergence in Pearl River Delta region.

同时通过对珠江三角洲地区9城市1993－2007年面板数据的回归分析，珠江三角洲地区确实存在σ-趋同和条件β-趋同。

By analysis of such models, a method, which is used to find out the region of convergence and to study the local stability for strong nonlinear system, are derived. Thus, we can consider the strong nonlinear neural networks using such method.

利用新的比较方法，考虑了具变时滞和常恢复率的同质人群HIV梯度传染病模型，得到了一个阈值，当阈值小于1时，疾病消除平衡点全局指数渐近稳定，当阈值大于1时，传染病平衡点存在唯一，同时得到该传染病平衡点局部指数渐近稳定的充分条件。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
