充分条件

Some sufficient criteria were obtained for oscillation of all solutions of such systems under first boundary value conditions by employing Gauss＇ divergence theorem, the integral inequalities and some results of the functional differential equations.

研究一类具非线性扩散系数的中立型双曲泛函偏微分方程组的振动性，利用Gauss散度定理、积分不等式和泛函微分方程的某些结果，获得了该类方程组在第一类边值条件下所有解振动的若干充分判据，结论充分表明振动是由时滞量引起的，同时也揭示该类方程组与普通双曲型偏微分方程组质的差异。

The paper consider actual conditions of Hebei , and carefully analyzied the questions in highway investment and financing. Considering of country investment and financing heavy policy environment, it proposes that Hebei should not stay the highway investment and financings " wait for, by, take ", relying on governmental investment simply, but should fully give play to the role of capital market and financial market. In insist of the policy on " interconnected system loan interconnected system return ", attract social fund extensively, form the macroclimate that the society runs the traffic;Consider the highway assets of the whole province as a whole, make the financing scheme , vitalize the assets. Through capital market, take bid way, project jointlies operate, corporatization, shareholding system, try such ways as franchise operation ,etc. boldly in newly-built project. At the same time, devote more efforts to standing in the government"s policy to highway, set up the capital construction of highway development. Turn to capital market management focal point , investment and financing of management from project management, change direction " melt" from " throw ", open up with innovative idea dissolving enter road construction practice really, try some new financing methods boldly , only in this way , could arouse every side"s enthusiasm further , really open up the unexhausted source for the benign development of road construction of Hebei.

本研究报告充分考虑了河北省的实际情况，对河北省公路投融资工作中存在的问题进行了深入、细致的分析，针对目前国家在公路投融资大的政策环境，提出了河北省公路投融资不能停留在"等、靠、要"，单纯依靠政府投资上，而是应该充分发挥资本市场和金融市场的作用；在坚持省交通厅"统贷统还"的政策下，广泛吸引社会资金，形成社会办交通的大气候；将全省的公路资产统筹考虑，制定融资方案，将资产盘活：通过资本市场，采取招投标方式，将有条件的公路项目进行合资合作、公司化、股份制改造，新建项目大胆尝试特许经营等方式：同时加大政府对公路的政策支持力度，建立公路发展基建；将投融资管理的重点，从项目管理转向资本市场管理，从"投"转向"融"，把开拓与创新理念真正溶入公路建设实践，大胆尝试一些新的融资方法，只有这样，才能进一步调动各方积极性，真正为河北省公路建设的良性发展开辟不竭之源。

Another one is the lack of accurate understanding of operator "s need and proper administrable structure. Under the condition of market economy, operator"s incentive payment should sufficiently reflect human capital deposit, human capital price, human capital value as well as operators needs. The author points out this is the essential way to resolve the problem.

在市场经济条件下，经营者的激励报酬必须充分考虑经营者人力资本存量、市场定价，充分考虑经营者的人力资本价值及经营者的实际需要，笔者认为这些是解决我国国有企业经营者薪酬激励机制问题的基本思路。

Confronted with the complicated domestic and international situation,we should recognize the favorable conditions and positive factors ineconomic and social development, and strengthen our resolve andconfidence in overcoming difficulties.

在错综复杂的国内外形势下，我们既要看到经济社会发展的有利条件和积极因素，坚定战胜困难的决心和信心；又要充分估计形势的不确定性、不稳定性，保持清醒头脑，增强忧患意识，宁可把形势估计得严峻一些，把困难考虑得充分一些，做好应对更大困难的长期准备。

Composition requires that it be used only in situations where it can be protected adequately from the intraoral environment.

需要在与口内环境充分隔离的条件下，Dycal的溶解性和基本特性才能充分发挥。

The results show that the alloy undergoes obvious plastic elongation, the specimen fractures into four sections and the diameter changes from 16 mm to 12 mm. The fracture surfaces distribute randomly well developed and partially developed veinal patterns. The deformation behavior of alloy is non-Newtonian flow behavior. About 3% amorphous matrix of extruded specimen transforms crystal, the crystal particles with size of 10-20 mm are precipitated in the amorphous matrix, the thermostability of the extruded specimen was lowered. The failure of the alloy is mainly attributed to non-uniform viscous flow under high strain rate resulting from the hydrostatic extrusion process.

结果表明：非晶合金在高应变速率下产生了明显的塑性变形，直径从16 mm变为12 mm，断裂为4段，且样品断口上随机分布着充分发展与未充分发展的脉纹式切变带，由此可看出非晶合金的变形为非牛顿体变形行为；挤压后的样品约有3％的非晶相发生晶化，在非晶基体上析出10～20 nm的纳米晶粒，导致挤压后非晶合金的热稳定性降低；静液挤压高应变速率变形条件使非晶合金产生非均匀流变，是造成非晶合金断裂的主要原因。

When the temperature of smoke inpouring air preheater increases, aggregate fuels and sediments will combust in stated temperature conditions.

这些起火起因于燃料油的不充分燃烧，其结果是未充分燃烧的燃料油凝结和聚集在空气预热器的部件上，当进入空气预器的烟气温度增高时，沉积的燃料油被烘烤，当达到一定温度条件时，则可点燃这些燃料油污沉积物，造成火灾发生，这通常被称为空气预热器的二次燃烧。

From simulations and data of fire site, most air preheater fire often appear when boiler is started in cool state and standby which fuels of insufficient combustion coagulate and congregate on the parts of air preheater. When the temperature of smoke inpouring air preheater increases, aggregate fuels and sediments will combust in stated temperature conditions. It is called the second combustion of air preheater.
