小孔

B 、 If A operation can not yet get intact image,should take down the telecope,and then use the small pen shape stick aims at the two ostioles on the ocular lens side,anticlockwise upwards to rotate until get intact and clear image

A 的动作还未能达到全屏，可取下望远镜，用配件中的笔型调镜器对准望远镜目镜端上的任一个小孔逆时针向上微调，直至图象全屏清晰为止。

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。

The fix was easy, I just filled in the small holes with wood filler, sanded it flat, and painted over it.

伦敦定盘价容易的，我只是填补小孔与木材填料，磨光它持平，画权。

The air is divided into primary air, secondary air, burning rice husk, the one, secondary air ratio of 50:50, a cold wind from the furnace chamber 2 side of the water entering through the fabric wind deflector hood holes into the combustion chamber.

空气分为一次风、二次风，燃烧稻壳时，一、二次风之比为50：50，一次风从炉膛水冷风室二侧进入，经布风板风帽小孔进入燃烧室。

Pulse-type steam trap: Pulse-type traps are two plates down according to changes in vapor pressure regulating valve switch, even if the valve is completely closed the entry and exit points are also through SAFETY VALVES the first and the second hole interlinked, remains not fully closed, steam constantly overflow, large amount of steam leakage.

脉冲式疏水阀：脉冲式疏水阀有两个孔板根据蒸汽压降变化调节阀门开关，即使阀门完全关闭入口和出口也是通过第一、第二个小孔相通，始终处于不完全关闭状态，蒸汽不断溢出，漏汽量大。

Pulse-type traps Pulse and two orifice traps are down according to changes in vapor pressure regulating valve switch, even if the valve is completely closed the entrance and exit is through the first and the second hole connected, always not fully closed, the steam constantly Yat out Water Power Control Valves steam leakage large.

脉冲式疏水阀脉冲式疏水阀有和两个孔板根据蒸汽压降变化调节阀门开关，即使阀门完全关闭入口和出口也是通过第一、第二个小孔相通，始终处于不完全关闭状态，蒸汽不断逸出，漏汽量大。

The working principle is: compressed air into the oil mist from the input device, the vast majority of the output by the competent Road, a small part of the airflow into a pole on the positive direction of the airflow holes a, through the valve into the oil cup 5 c in the upper chamber, so that pressure on the oil surface.

其工作原理是：压缩空气从输入口进入油雾器后，绝大部分经主管道输出，一小部分气流进入立杆1上正对气流方向的小孔a，经截止阀进入储油杯5的上腔c中，使油面受压。

A theoretical model for ST type pulse tube refrigerator is set up and numerical results are achieved with this physical model.
