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。

在充满电介质的空间里，库仑定律应为：F＝kQ1Q2r2.V在电场作用下电介质极化产生束缚电荷，束缚电荷在介质内部产生电场，与外电场方向相反，所以使外电场减弱。
