For the structure that the side-frusta is also used as retain wall,considering the side frusta fastened on the weir body,the plane stress is calculated at first. Then the moments,horizontal shear force and vertical force on the bottom of the retain wall are applied as fixate,and stress distribution on the weir body are calculated piecewise.

对于边墩兼作挡上墙结构，通常是将边墩视为固端于岩体上，先进行下端为固端的挡墙平面受力计算，再将挡墙下部的弯矩、水平剪力和垂直力作为集中外荷载进行堰体的应力计算，堰体也只能分段进行片面受力计算。

Appropriate model and space discretization were chosen to simulate the loading process of specimens conducted on the Split Hopkinson Pressure Bar in two-dimension,and the adiabatic shear deformation course of the hat-shaped specimen under high strain rate was obtained.

通过选择恰当的模型和科学的空间离散化，对SHPB加载过程进行了2D数值模拟，数值重现了帽型试样高应变条件下的绝热剪切变形历程。

Using high frequency induction brazing and TiZrNiCu filler metal, the shear strengths of the joints were low. The maximum shear strengh was only 102.1MPa, which was lower than the maximum strength of vacuum brazing. The reasons may be that excessive intermetallics, holes and oxidation existed in the joint. So TiZrNiCu filler metal isn't fit for non-vacuum brazing.The stress variation, stress distribution and crack-sensitive regions during the cooling process of brazing have been studied by Marc non-linear software.

采用气体保护高频感应加热、TiZrNiCu钎料钎焊时，接头的强度普遍偏低，最高的剪切强度只有102.1MPa，远远低于辐射加热真空钎焊的强度，其原因是接头中局部生成了过量的金属间化合物，且产生氧化，接头中含有较多的气孔等影响了接头强度，因此可以认为TiZrNiCu钎料不适合在非真空条件下的钎焊。

Here is Bill Jukes, every inch of him tattooed, the same Bill Jukes who got six dozen on the WALRUS from Flint before he would drop the bag of moidores ; and Cookson, said to be Black Murphy's brother, and Gentleman Starkey, once an usher in a public school and still dainty in his ways of killing; and Skylights (Morgan's Skylights); and the Irish bo'sun Smee, an oddly genial man who stabbed, so to speak, without offence, and was the only Non-conformist in Hook's crew; and Noodler, whose hands were fixed on backwards; and Robt.

接着是比尔·鸠克斯，浑身上下都刺满了花纹，就是那个在海象号船上被弗林特砍了七十二刀才丢下金币袋的比尔·鸠克斯。还有库克森，据说是黑默菲的兄弟。还有绅士斯塔奇，曾在一所中学当过助理教员，杀起人来，还是文质彬彬的。还有&天窗&。还有爱尔兰水手长斯密，他是个特别和蔼的人，他就是捅人家一刀，也不会得罪人家；在胡克的水手班中，他是唯一不信国教的。还有努得勒，他老爱背剪着手。

The results indicate that the μ of the asphalt mixtures has significant effect on the maximal lateral and shear strains. When the modulus ratio of the top and middle lagers is less than 0.8 and the μ of the asphalt top layer increases to a certain extent, the asphalt mixtures around the edge of wheel mark tend to flow towards both sides of the rut under the action of load, leading to the unstable rut.

结果表明，沥青面层的泊松比对沥青路面结构的最大横向应变和最大剪应变有显著影响：当上中面层模量比小于0.8且沥青面层泊松比增大到一定程度时，轮迹带边缘的沥青混合料在荷载作用下有向车辙两侧流动的趋势，容易产生失稳性车辙。

Liger 87-5 was used as test material to study leaf-removal and irrigation on the growth of tomato fruit under water controlling.

In order to find out the main influence factor to the water stability of granite asphalt mixture and make large-scale use of granite aggregate in asphalt pavement possible. dynamic shear rheometer was used to study the rheological properties of asphalt mastics with different granite powders and different filler-asphalt ratios to analyse the interaction ability between different granites and asphalt.

为了找出影响花岗岩沥青混合料水稳定性的主要因素，使花岗岩大规模应用于沥青路面成为可能，从花岗岩沥青胶浆着手，采用动态剪切流变仪，对不同花岗岩石粉、不同粉胶比条件下的沥青胶装进行流变性能的研究，以此分析不同花岗岩与沥青交互作用能力。

are gained that after widening, the settlement of two sides of the old road pavement is contrary, cross slope of old road is different, horizontal displacement of the old road pavement is minishes, the area of maxium settlement, maxium lateral displace and disease of old road is different as before widening.

分析结果指出：在拓宽段作用下，靠近老路中心一侧老路路面沉降逐渐减小，远离老路中心一侧沉降逐渐增大，相应横坡也在发生变化；老路路面的水平位移有较大幅度的减小；而且老路最大沉降、最大水平位移、最大剪应力及最易发生病害的位置与拓宽前也发生了较大的变化。

After carries on the load computation and the component section estimate, selected a pin frame to carry on the computation, the computation content including the frame beam column section size selection and the line rigidity computation; Dead load, live load, under earthquake function Liang Duan, column end moment, shearing force computation; Frame endogenic force combination; The frame beam column matches the muscle computation; The staircase matches the muscle computation and the foundation matches the muscle computation.

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。
