But getting them out of their shells is tiring without machion. In 2001, a Canadian inventor Jock Branders Brandis designed the hand out an hand-powered peanut sheller for a village in Mali.

不过在没有机械帮助的情况下脱去花生壳是件很麻烦的事。2001年，加拿大发明家Jock Brandis为马里的一个小镇设计了一种手动花生剥壳机。

The monoclonal cells were selected using cloning rings. The expression of capsid protein was detected by indirect immunofluorescence and sandwich-ELISA. The empty capsids of FMDV were observed under electron microscope.

经间接免疫荧光和酶联免疫吸附测定（Enzyme-linked immunosorbent assay，ELISA）方法检测MDBK细胞中衣壳蛋白的表达，并在电镜下观察口蹄疫病毒空衣壳。

On the basis of the results and methods of the researches done at home and abroad the analytical model of finite element has been built according to the formation and behavior of I-section plate girders with stiffeners.

实际工程中的板件由于存在初始几何缺陷或在荷载作用下发生屈曲变形后，便具有了壳体的特征，因此文中采用板壳的曲壳有限元分析方法。

Fissa, C. chinensis and P. massoniana under full sunlight was by 42.6%, 32.6% and 4.2% higher than that under shade, respectively. The UV-B absorption of cell wall-bound alkali extractable phenolics in leaves of C. concinna and S. superba grown under full sunlight was by 35% and 11.7% higher than that under shade, respectively. But it was lower in leaves of P. massoniana, C.

全日光强下的黄果厚壳桂和荷木叶片细胞壁碱性酚类提取物的UV-B吸收能力亦分别比遮阴下的高35%和11.7%，而马尾松、锥树和藜蒴则较遮阴下的低，可能这些树种在全日光下细胞壁UV-B吸收物质有部分转移到细胞质，以增强栅栏组织细胞的保护。

The results indicated that the composite membrane contained 9.47±2.44% chitosan/PVA component. Chitosan and PVA in the membranes were crosslinked by treatment with glutaraldehyde vapor at 37°C.

在37°C下用戊二醛蒸气交联电纺膜中的壳聚糖/PVA组分，进而通过拉伸实验来评价各种电纺膜的力学性能，结果表明交联后的PLGA-壳聚糖/PVA复合膜集聚了两个组分的优点具有较好的力学性能。

Impeller rotates clockwise, the right part of the space between two blades is gradually increasing, in confined conditions, with the air volume increases, pressure decreases, the formation of vacuum pumps and air through the pipeline suction tube into the vacuum pump the right side of the crescent-shaped shell inspiratory mouth to be sucked into vacuum pump, vacuum pump impeller left some space between the two blades is gradually reduced, so the air is compressed, the pressure then increased, and finally through the vacuum pump shell crescent-shaped exhaust port from the left side of vacuum pumps, gas separator into the water box, so that was taken out after the separation of the recycled water reuse.

叶轮顺时针方向旋转时，其右半部分两叶片之间的空间逐渐增大，在密闭条件下，随着空气体积的增大，压力随之降低，形成真空，水泵和管路内的空气通过吸气管，进入真空泵泵壳右侧的月牙形吸气口被吸入真空泵，真空泵叶轮左半部分两叶片之间的空间是逐渐减小的，因此空气被压缩，压力随之增高，最后通过真空泵泵壳左侧月牙形排气口排出真空泵，进入水气分离箱，使被带出的循环水分离后再重复使用。

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。
