Terahertz radiation, which is a kind of electromagnetic wave between the infrared and microwave bands, belongs to far-infrared band. THz time-domain spectroscopy which developed in the 1980\'s has the advantages of high signal to noise ratio, obtaining the absorption coefficient and refractive index of the sample at one time , low energy that can not distroy the biology organise and so on.

太赫兹辐射是指频率位于微波和红外光之间的电磁波，属于远红外波段；20世纪80年代发展起来的THz时域光谱技术，具有信噪比高，能同时获得样品的吸收系数和折射率，能量低，不会对生物组织造成破坏等优点，在材料和生物学等领域得到了迅速的发展和广泛的应用。

G. Lekhnitskii and the Hankel integral transformation are used, And thereby a solution of the Stress field and displacement field of an embedded penny-shaped crack lying in a transverely isotropic plane under the action of the uniform tension stress at the far end perpendicular to the crack surface is obtained.

本文利用对于横观各向同性体轴对称变形时应力函数解法的基本方程，并应用Hankel积分变换，求解了位于横观各向同性平面内的埋藏圆片裂纹在垂直于裂纹面远处均匀拉应力作用下的应力场和位移场，获得了与各向同性材料相同的应力强度因子，不同于各向同性材料的应力场和应变能释放率裂。

Is better than that of using Na〓S merely and the profit per year is over 6, 000, 000 yuan. External potential-control flotation column and The Cu-Mo bulk concentrates flotation separation. With appropriate combination of the principle of sulphide flotation pulp electrochemistry and the technology of flotation column show the advantage over flotation equipment, External potential-control flotation column was studied successfully, laboratory potential-control flotation column was designed and its structural principle, the relationship of electrode structure and the activity of separation, the electrochemistry principle of potential-control flotation column also was investigated.

用具有较强电化学还原能力的无机物（如硫化钠、连二亚硫酸盐等）与能和硫化铜矿物表面发生选择性吸附的小分子有机化合物组合使用、成功地实现了混合精矿体系中黄铜矿的抑制、解决了德兴铜矿铜钼混合精矿浮选分离时、硫化钠用量大、生产成本高，生产指标不稳定的技术难题，研究结果表明，用组合抑制剂3.8kg/t可取代生产中硫化钠45kg/t的高用量，并获得优于单用硫化钠的好指标，年直接经济效益600万元以上。

This industrial leader doesn't put much faith in the old adage that hard work alone is the magic key that will unlock the door to our desires,"I have known people," he said,who succeeded because they had a rip-roaring good time conducting their business.

而不是苦干、钻研的去打开他成功的大门。他曾这样说：「有若干人，开始一桩事业的时候，怀着极大的希望和兴趣，所以能在早期获得部份的成就。

The spores of Cheilolejeunea ventricosa X.L.He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.

首次研究了膨叶唇鳞苔的孢子萌发、原丝体和油体发育及配子体发生的过程，结果表明：(1)使用经过改良的MS培养基（不加氨基酸和维生素，pH值为6.2，琼脂和蔗糖浓度均为1%）能在55 d左右的时间利用孢子培养获得植物体；(2)用0.1%的次氯酸钠溶液，消毒5 s是消毒孢子的最佳方案；(3)油体在孢子萌发初期为均一型，到幼叶发生后，成为可见的聚合型，但聚合的程度比野生材料要弱。

Next, the Bandelet transform is taken on each directional subband. The proposed multidirectional and multiscale transform with critical sampling can represent the geometrical features such as edges and texture more sparsely, which is of great benefit to image compression.

原始的Contourlet变换有大于1的冗余度而不适于图像压缩的要求，采用传统的张量积小波变换取代其中的拉普拉斯金字塔式变换可获得非冗余的变换形式[8]，Bandelet变换是一种基于图像边缘的变换方法，它能自适应地跟踪图像的几何正则方向。

For if goodness can only be in God, if it cannot exist separate from Him, if He can only bless and sanctify, not by a creaturely gift, but by Himself becoming the Blessing and Sanctification of the creature, then it is the highest degree of blindness to look for any goodness and happiness from anything but the immediate indwelling union and operation of the Deity in the life of the creature.

称永久代祷的人是宗教狂热者是何等毫无理由，至少在单单真实的从神获得启示的生命，是无法得到良善和喜乐，那就不可能同意此说，因为良善无法与神分离而单独存在，除非借他自己所变成有福而圣洁的人否则没人能有此种生命，惟有直接从内住的神得到启示，否则没有高级受造之物，可从其他地方找到良善和喜乐，根据永远的启示：动物怎样需要空气而高级受造物也怎样需要有良善、圣洁和喜乐的本性。

We screened a set of Lewis base organocatalysts derived from chiral pipecolinic acid and tert-butanesulfinamide for the reduction of-N-Cbz-1- phenylpropenamine, including newly designed ones and some of those previously developed in our lab. However, only moderate stereoselectivities, albeit high yields were obtained.

在本课题组前期研究的基础上，我们筛选并设计了一系列以手性哌啶酸和叔丁基亚磺酰胺为母体的有机小分子路易斯碱催化剂，它们能催化三氯氢硅对-N-苄氧羰基-1-苯基丙烯胺的不对称还原，获得很高的收率和中等的对映选择性，并且具有很好的底物普适性。

Making Puer tea as internationally renown as Roquefort cheese could expand China's tea exports while adding a bit of luster to a food industry infamous for its health scandals.

使普洱茶获得像奶酪吐司那样的国际声望将会扩大中国的茶叶出口，同时能为它那因为不卫生的丑闻而臭名昭著的食品产业增加一些光彩。

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。
