We have conducted measurements in heterodyne detection including superconductor mixers and semiconductor harmonic mixers, direct detection including InSb semiconductor bolometer and Golay Cell, and some materials which could be permeated by terahertz waves.

测得的频谱分辨率可达约1 GHz。我们已经测量的器件有：超导隧道结混频器和工作于常温的半导体肖特基谐波混频器，InSb半导体Bolometer和Golay Cell直接检测器，各种频率的THz信号源，和一些能透过THz的材料等。

The hardness and wear resistance increase with increasing TiB2 content. Adding about 1.5%Mg in melt restrains the conglobation of the TiB2 particles, which makes the size of TiB2 particle decrease and the distribution of TiB2 particle is more homogeneous. The strengthening effect of TiB2 particles is enhanced and the hardness and wear resistance of composites are obviously improved. The excess Mg decreases the refinement effect of TiB2 particles, but the hardness and wear resistance are improved continuously.

结果表明：反应生成的TiB2颗粒平均尺寸约为0.5 μm，材料的硬度和耐磨性随着TiB2含量的增加而提高；添加1.5%Mg元素可明显细化TiB2颗粒，且使其分布更加均匀，增强TiB2颗粒的弥散强化和细晶强化效果，复合材料的硬度和耐磨性显著改善；过量的Mg元素(3%)会造成TiB2颗粒细化效果的下降，但其硬度和耐磨性能继续得到改善。

Want to know, the person's skin can be divided into three-layer of cuticular, dermal, subcutaneous tissue about; All maintaining the limits that tastes generation action is in only cuticular layer, in thin thin divided in the cuticular layer that is less than one centimeter 4, quintuplicate cell, be located in the bottommest for base layer, full vivid cell can grow ceaselessly reach dissension, slowly when upgrade is advanced, the cell can squash gradually, at the same time evaporate, nutrient, until most the corneous layer outside, already was flowing do not have the corneous layer cell of life however.

要知道，人的肌肤约可分成表皮、真皮、皮下组织三层；所有保养品产生作用的范围都仅在表皮层，在薄薄不到一公分的表皮层中分了四、五层的细胞，位于最底部为基底层，布满的活细胞会不断生长及分裂、慢慢往上推进时，细胞会渐渐变扁，同时失去水分、养分，直到最外的角质层，就已是平滑却没有生命的角质层细胞了。

This problem dates back to 1611, when Johannes Kepler conjectured that the best packing arrangement for identical spheres was arranging them in what is now called face centered cubic packing - similar to how one sees cannon balls stacked.

这个问题可追溯到1611年约翰尼斯·开普勒提出堆积等大球体最佳方法的猜想（译者注：当等大球体按照--球心位于正方体各面的中心上--的形式，并且将第一层摆放成六角形时，它们占用的空间最小，对空间的利用率可以超过74%），现在把这个方法叫做面心立体堆积法--类似于加农炮弹的堆积方式。1998年，安娜堡密西根大学教授托马斯·C·黑尔斯证明了这个猜想。

It have sufficient space to wash fiber balls in filter to increase efficiency of backwash .

逆洗的方式需先以逆向进水将滤层抬起，然后再以气、水联合冲洗，重覆约4~5次后可完成逆洗过程，耗水量只有0.12%，过滤器内部的高度则建议以纤维球的自然高度的二分之三倍为佳，使纤维球在过滤器内有足够的空间漂洗，增加逆洗的效果。

There is no visible light dispersion in the glass and it can take the place of traditional rare earth fluorescent screen in high energy radiography applications. For its spatial resolution will not be greatly reduced when its thickness increases in a certain range, a thicker glass can be used to reach a higher DQE.

针对特殊用途开发了一种新型掺Tb3+硅酸盐发光玻璃转换屏，可用于30 MeV的γ光子的成像探测；在低能X光(100 keV)作用下的空间分辨能力与301型发光玻璃相当，而在能量高达12 MeV的X光的照射下，其空间分辨能力不低于1.5 lp/mm，发光效率约为301型发光玻璃的3倍。

The study site is located at Wung-Fong Agricultural Research Institute where the interference caused by buildings which affect the wind direction to Eddy Covariance System can be reduced to the minimum. The measurement was made from 28th April to 5th June in 2009 through automated measurement and data logging system.

本研究场址为台中县雾峰农业试验所中的水稻田，由於附近并无太多的建筑物干扰风的行进，可对於干扰涡流协变性系统的因素减低到最少，实验观测期间为2009年4月28日至2009年6月5日止，实际实验天数约25天。

And they said, If ye send away the ark of the God of Israel, send it not empty; but in any wise return him a trespass offering: then ye shall be healed, and it shall be known to you why his hand is not removed from you.

撒上6：3 他们说、若要将以色列神的约柜送回去、不可空空的送去、必要给他献赔罪的礼物、然后你们可得痊愈、并知道他的手为何不离开你们。

Deierlein said the system he and his colleagues have developed is applicable to steel-framed buildings up to about 15 stories tall, but that the general approach could be modified for other types of buildings.

阿希望的涟漪效应Deierlein，说他和他的同事们开发的系统，适用于钢铁结构建筑高达约15层楼高，但一般的方法可用于其他种类的楼宇进行修改。

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。
