This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

本发明涉及一种冷原子束产生方法和装置，该方法包括在抽真空的真空室内，加热热原子源，在真空室中形成相应的原子饱和蒸汽压气氛；采用三维MOT对热原子进行冷却，冷却到200μk以下，并被捕获形成冷原子云团；通过三维MOT中开小孔的四分之一波片反射镜，而使得在该方向上激光辐射压力不平衡，使冷原子沿此方向出射；在冷原子束出射方向上，还置有载有彼此电流方向相反的四根成锥形排列的直导线，从而原子出射时将在磁场的作用下，不会沿横向膨胀而向前射出；便得到了出射速度低的、通量较大的、横向速度非常小的连续冷原子束；同时在冷原子束的出射方向上，设置有与原子束垂直的激光束，用于原子束的态制备，实现态一致的出射冷原子束。

Results Well-resolved, reproducible 2-DE profiles of human colon carcinoma tissues and paired normal tumor-adjacent colon tissues were obtained. For colon carcinoma tissues, a total of (980±28) spots were detected; for paired normal tumor-adjacent colon tissues,(860±45) spots were detected. For normal tumor- adjacent colon tissues, the average deviation of spot position was (10.487±0.11) mm in IEF direction and (0.944±0.12) mm in SDS-PGE direction; for colon carcinoma tissues the average deviation of spot position was (0.654±0.11) mm in IEF direction and (1.20±0.22) mm in SDS-PGE direction. Number of differentially expressed proteins was 72.00±12.34 between colon carcinoma and paired normal tumor-adjacent colon tissues.

Traditionally we continue moving forward with the paper in line with the direction of most of the fibers'packing is called straight grain direction; and a direction perpendicular to the horizontal paper called the grain direction.

习惯上我们把与造纸前进方向一致的大部分纤维排列的方向叫做直丝绺方向；与其垂直的一方向叫做纸张的横丝绺方向。

There is also a belief, from paper, paper direct comparison of the grain direction, easy-to-stiffness and transportation; blowing and horizontal grain direction of the paper is not enough stiffness to the two ends of the easy-to-source or curls, purging and transportation, so you should move the paper direction and straight grain feeding direction parallel to cards and membership cards.

还有一种说法认为，从输纸来看，纸张直丝绺方向比较硬挺，便于吹松和输送；而横丝绺方向纸张挺度不够，两头易于向下或者向上卷曲，影响吹松与输送，所以应将纸张直丝绺方向与输纸方向平行来制卡和会员卡制作。

Self-fluxing Fe-Cr-Ni-B-Si alloy prowders are laser clad on medium carbon steel substrate of dimensions 80×35×10mm〓. The investigation results of this clad layer are: micro-defects, micro-cavity and occluded forin substance, are the micro-cracks and crack resourses in clad layer; crack of coating propagates along the boundary of two kinds of eutectic sutructure; The included angle θ between the cracking direction and laser scanning direction in multitrack overlapping clad is smaller than that in one-track clad because of crack propagating along crystalline growth direction and crystalline direction in overlapping zone being different from it in one-track clad.

在调质态的45〓钢表面，采用预置粉末法进行FeCrNiBSi合金的多道搭接激光熔覆，对其熔覆层进行分析表明：多道搭接激光熔覆层裂纹扩展方向与激光扫描方向间的夹角θ与单道熔覆时相比明显变小，前者θ0°，后者θ角基本都为90°，这主要是因为多道搭接时，搭接区结晶方向发生了变化以及裂纹沿结晶方向扩展所致；激光熔覆层裂纹大多是以覆层与基材交界面的孔洞、熔覆层内不同方向共晶团间的显微缩孔、夹杂物的边界等三种显微缺陷作为裂纹源，并沿低熔点物相形成元素偏析造成弱化膜的共晶团界面扩展延伸。

For chirp radiator direction-finding using an ARM interferometer seeker, the cause of the direction-finding error using traditional direction angle estimation is studied, and the relationship between the direction-finding error and the integration time is analyzed, especially for the boundary condition that the integration time of phase discriminators gets the maximum value.

The Lynn White debate, which begun when White called for a rethinking of Christianity or its replacement by a nonWestern religion, has proved an obstacle to dealing with the environmental crisis The defense of Christianity that followed inhibited Asian and comparative environmental ethics in the West and did not produce environmentally useful results Whenever the relationship of religion and the environment was raised, the discussion quickly shifted to the issue of Christian responsibility for the environmental crisis The problem with the debate is that in many important ways, the White thesis is correct: Christianity is indeed responsible to a significant degree in that Christianity desacralized nature and it supported policies politically in the Middle Ages that encouraged now harmful human population growth and promoted science and technology, much of which has proved to be environmentally problematic There was nevertheless a second tradition of which Saint Francis of Assisi was a part that was environmentally friendly and that could be useful in rethinking Christianity environmentally It is however unlikely that Christianity will prove useful in the development of an environmental ethic in nonWestern countries or that nonWestern religions will succeed in producing an environmental ethic in the West It is therefore important that religious scholars move beyond assigning blame for the environmental crisis and find ways for the major world religions to help develop environmental ethics as best they can within their own cultural spheres

林恩怀特争论始于怀特关于对基督教进行重新思考或者由非西方宗教取而代之的呼吁。林恩怀特争论已经被证明成为处理环境危机的一个障碍。由此而起的对基督教的辩护制约了亚洲和其他比较环境伦理学在西方的发展，没有产生对环境有益的结果。无论何时，当人们谈及宗教和环境的关系的时候，讨论都会迅速转向有关基督教对环境危机责任的讨论。这一争论的关键在于，怀特的论文在很多方面是对的：基督教的确在相当大的程度上造成了自然的世俗化，并且在中世纪，基督教在政治上对现在看来有害的人口增长的政策提供了支持，促进了科学和技术的发展，很多诸如此类的政策已经被证明对环境是有害的。但是，基督教还存在另一种对环境友好的传统，Assisi城的&圣芳济&运动就是其中一例，这种传统也许对于从环境角度重新认识基督教是有益的。但是，对于非西方国家环境伦理的发展，基督教将很难能够有所作为，非西方宗教也不大可能成功地在西方产生出某种环境伦理。因此，对于研究宗教的学者们而言，重要的是要走出谁应该为环境危机受到指责的争论，找到世界各主要宗教如何在其各自的文化范围内对发展环境伦理提供最佳帮助的方法。
