Results of analysis show that Generalized Paris Law can consider the complex crack propagation in the material of the pavement structure. The fatigue life of the pavement increases with increasing thickness of surface layer in a power function. Use of a thicker surface layer may extend the service life of the asphalt pavement. The fatigue life increases with decreasing modulus of surface layer in a power function with a negative exponent. However, since reduced modulus would scarify the structural strength and might cause rutting-related distress, caution should be taken when using low modulus materials for improving fatigue performance of asphalt pavements. The fatigue life increases with increasing modulus of base material in a power function. However, the fatigue life can not infinitely increases with increasing modulus of the base.

计算与分析表明：广义Paris公式可以考虑沥青路面结构内材料复杂的裂缝扩展：沥青面层的疲劳寿命随着面层厚度的增加以幂函数的形式增加，适当增加沥青面层厚度可以提高路面的使用寿命；沥青面层的疲劳寿命随着面层材料模量的降低以负指数的幂函数形式增加；由于材料模量的降低将牺牲路面的整体强度并可能引起路面车辙类损坏，以此提高疲劳寿命的方法应慎重对待；沥青面层的疲劳寿命随着基层材料模量的增加呈幂函数的形式增加，但由疲劳方程可以看出，寿命并不是随基层材料模量的增加而无限的增加，疲劳曲线在经过一个上升段后，逐渐趋于一个常数值，这说明，这时基层模量对寿命已不作关键性贡献；随着底基层厚度的增加，面层的疲劳寿命近似地呈线性函数增加，但效果并不很明显。

It shows in clinic as tooth sensitivity, pulpitis,periodontitis,food impaction ,deformation of basifacial caused of loss of occlusal height, temporomandibular disorder syndrome, etc. The wear property of artificial tooth material will lead a direct effect to restoration result, when it exists in oral environment. It will cause tooth enamel loss too much in a very short period, if the wear property of artificial tooth superior to tooth enamel; but if it is inferior to tooth enamel, serious wear will occur on restoration occlusions, which will lead to loss of bite functions and even decrease of occlusal vertical dimension, disorder of bite functions, etc. Therefore, it is important to artificialtooth material not only it"s biotic compatibility, mechanical function, chemistry property but also it"s wear property.

当口腔中存在修复体时，人工牙材料的磨耗性能也直接影响临床修复的效果，当其磨耗性能强于天然牙釉质门时，将会引起天然牙釉质过度磨耗；当其磨耗性低于天然牙釉质时，又会在较短时期内引起修复体咬合面磨损过度，失去咬合功能，严重者甚至出现咬合垂直距离降低，咬合功能紊乱等症状因此，对于人工牙材料除了考虑生物相容性、机械性能及化学性能外，还应考虑到材料的磨耗性能，而磨耗率的测定一直是评价天然牙及人工牙磨耗性能的优越指标之一。

When a metal is plastically deformed, interactions in the material's structure can cause the material to become stronger and harder.

当材料发生塑性变形时，材料内部的组织变化引起材料的强度和硬度增加。

But the concrete is non- one kind homogenizes the fragility material, under having certain temperature and humidity situation, the concrete is hardened and produced the volume out of shape, he is out of shape and inconsistent because of making up the material of the concrete, restrain from, produce initial stress each other, cause between aggregate and stone bonding surface of cement or cement produce the very small crack between the stone,These cracks are irregular, discontinuous too, under the influence of external factor, may also develop into a macroscopical crack.

但混凝土是一种非匀质脆性材料，在具有一定的温度和湿度情况下，混凝土硬化并产生体积变形，由于组成混凝土的材料其变形不一致，互相约束产生初始应力，造成在骨料与水泥石粘结面之间或水泥石本身之间产生微细裂缝，这些裂缝既不规则，也不连贯，在外界因素影响下，还可能发展成宏观裂缝。

It imply in the smoke a kind of call nicotine of harmful material, the person inhales this kind of material over a long period of time, will cause...

烟中含有一种叫尼古丁的有害物质，人长期吸入此类物质，将会导致。。。

I understood that the rubber sizing material process presses out makes certain shape semifinished materials, becomes the half-finished product to cause it with to delay the rubber or the rubberizing textile material after the pressure combines is taking shape together, but the mold design manufacture's request talented person can grasp the system regulation criterion, must be precise, processes the mold to be bright and clean, but these two aspects advertise for the administrative personnels now many enterprises are the request are strict, also needs to arrive at the workshop to practise first exercises one year even longer time, because makes technical the need in reality multi-accumulation experience, finds the problem, the familiar workshop service, masters more knowledge, can the better managerial talent.

In its original senses materialize is used intransitively to mean "to assume material form," as in Marley's ghost materialized before Scrooge's eyes, or transitively to mean "to cause to assume material form," as in Disney materialized his dream in a plot of orchard land in Orange County.

materialize 的最初含义是作为不及物动词时意思是&具有物质形式，&例如在玛雷的鬼魂在斯克鲁奇眼前显现了一句中或作及物动词时意思是&使具有物质形式，&例如在迪斯尼在奥兰治郡的一块果园实现了他的梦想中。

Homogeneous or heterogeneous base material is selected; an alternately superimposed barrier layer and an alternately superimposed recessed layer are grown and formed at the extension of the base material; donor impurity and acceptor impurity are doped in the interface between the barrier layer and the recessed layer and in the interface between the recessed layer and the barrier layer, and the p type group III nitride material doped at a position selecting superlattice is obtained.

选择同质或者异质的基质材料；在基质材料上外延生长形成变换叠加的垒层和阱层，在垒层与阱层的界面和阱层与垒层的界面掺入施主杂质和受主杂质，得选择超晶格位置掺杂的p型III族氮化物材料，其中，每个生长周期的步骤为：生长带隙较宽的垒层，同时掺入受主杂质；生长施主杂质或受主杂质δ掺杂层；生长非掺的带隙较窄的阱层；生长受主杂质或施主杂质δ掺杂层；在N 2 气氛下对所得的选择超晶格位置掺杂的p型III族氮化物材料退火，即得目标产物。
