极限化

The silicon MOSFET which has powerful furiction and is widely used in to-day's VLSI chip designs is on the verge of its technology limits when the transistor sice becomes much smaller,the new approach is being explored ceaselessly.

摘 要：目前微电子芯片中功能强大的、广泛使用的硅晶体管从微型化的角度说已接近其技术极限，新的技术途径在不断探索之中。

"Up to the limit" is an art work about time. On the surface, this art work tests people's tolerance of extreme tedium of endless routine labor and unbearably apathic physical space where one can hardly stay long. But the concept of time emerges during the process of close references with the formation of the work; moreover, a hidden craziness opposite to the apathy of the work sharply stabs into the viewers' eyes and further thrusts into their hearts; and it is exactly during the process of watching, that time settles down and achieves its existence.

极限》则是一组以时间为题的作品，表面看作品是在考验一种无穷尽的忍受，一种冷漠无比的枯燥，一种不能存留的短暂的物理空间，一种样式化的不断重复的工作，时间之概念恰在这一系列与作品形成密切相关的制作当中浮现出来，并以一种与作品的冷漠完全相反的隐藏起来的疯狂，尖锐地插进观看者的双眸，并延伸到其内心，时间恰好在这观赏的过程中得以落实，而成为一种实存。

For some rock slopes, which have not distinct failure surface, but have complicated structure or load on the top and so on, a stability analysis of this type slopes by finite element method is presented, the failure surface is defined by certain rule or strain zone from the computed model, and then the safety factor of the rock slope is abtained by finite element method and limit equilibrium methodAt last, using ANSYS , a famous commercial finite element analysis software, a example of high-steep slope which is bearing the load of the LongGe Mansion is presented, the stability of this slope is studied, as a paradign the the stability evalution of complicated high-steep slope under the action of load of building , the chapter gives some meritable reference in stability assessment of rock slopes using numerical simulation by three-dimension elastic-plastic finite element.

并用有限单元法建立边坡的具体模型，应用折减边坡岩体参数、逐级施加荷载等与边坡工作环境相似的方法进行模拟计算，根据计算结果，采用一定的判别准则或图形可视化方法，确定出边坡的滑裂面，再采用刚体极限平衡法或有限单元法计算其安全系数；最后，通过某一工程实例，用大型有限元程序对边坡在建筑物荷载作用下的稳定性进行分析研究，并以此作为计算分析复杂高边坡在高层建筑物作用下的稳定性评价的一个范例，在采用有限元弹塑性数值模拟岩质边坡稳定性方面提供一些有价值的参考。

The strength of HSLA steel with ferritic plus pearlitic mierostruetures has attained the limited value of 450～500MPa by traditionally microalloying treatment and TMCP. In order to further improve the strength grade, low carbon bainitic steel plates should be developed.

通过采用形变热处理工艺和微合金化，在保证高韧性和优异的焊接性能的条件下，具有铁素体珠光体组织的低碳低合金高强度钢的屈服强度可以达到500～550MPa的极限水平。

Results showed that the synergistic action of brominated epoxy 10% and Sb2O3 3% could improve the limiting oxygen index from 18 to 30 and gave good mechanical performance to PU coatings.

结果表明当溴化环氧用量为10%，在3%的Sb2O3协同作用下，可将聚氨酯涂料的极限氧指数从18提高到30，同时能保证聚氨酯涂料优良的物理机械性能。

Based on the durability characteristics of prestressed concrete structures,the durability limit states of carbonation and chloride ion attack are defined,respectively.Durability predicting models on the basis of reliability mathematics and stochastic processes are constructed,and the pure theoretical formulae of failure probability of prestressed concrete structures are analyzed.

根据预应力混凝土结构的耐久性特点，分别定义了结构构件在碳化环境和氯离子侵蚀环境下的耐久性极限状态，建立了以可靠性数学和随机过程为理论基础的数学模型，并对耐久性失效概率进行了理论分析。

For now, however, I won't be riding in a jet whose software was rapidly prototyped by an extreme programmer.

不过，目前，我还没有遇到过被极限编程员迅速原型化编写出来的软件。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
