In the second part of of this thesis, we firstly derivate the operation condition of intracavity SHG of dualwavelength laser from the rate equation, and then numerically calculate the relationship between the laser operation parpmeters and the pumping powers. And then we discuss two possible ways to get balancing outputs of the harmonic waves of the two wavelengths. By comparing the two ways, we find that the method by increasing the geometrical factor of 1079. 5nm SHG has the higher efficiency than the method by adding the additional loss of 1079. 5nm basic wave. Besides, the first method is easier to realize in experiment than the second method.

本论文第二部分从速率方程出发，通过求解速率方程的稳态解得到了Nd：YAP腔内倍频双波长激光的连续运转条件，数值计算得到了随泵浦功率变化的激光运转情况；计算、分析了通过增加主波长的倍频耦合几何因子和增加主波长的腔内损耗两种方法获得均衡的双波长倍频输出的运转情况，通过二者的比较，发现增加倍频耦合几何因子的方法比增加损耗的方法效率更高，而且在实验上更易于实现。

However, as the Sun bak'd these Two, very dry and hard, I lifted them very gently up, and set them down again in two great Wicker-Baskets which I had made on purpose for them, that they might not break, and as between the Pot and the Basket there was a little room to spare, I stuff'd it full of the Rice and Barley Straw, and these two Pots being to stand always dry, I thought would hold my dry Corn, and perhaps the Meal, when the Corn was bruised.

无奈之中，只得用一把腰刀来改做；这种腰刀是我从船上的武器舱中取出来的。好在第一次收成不多，所以割起来也没多大困难。而且，我收割的方法也非常独特：只割下麦穗或稻穗，把茎干留下来。我把穗子装进自制的大筐子里搬回家，再用双手把谷粒搓下来。收获完毕后，我发现原来的半斗种子差不多打了两斗稻和两斗半多的大麦。这当然只是我估计估计罢了，因为当时手头根本就没有量具。

Butt Weld and docking and corner combinations Weld, in Weld ends located arc plate and extraction plate in igniting board then leads to the welding seam, joint halfway shall weld joints in front of 2.0 mm Department Firing arc, welding pieces after preheating rod will return to weld the origin, pool filled to the required thickness, before forward welding; Welding speed : Isokinetic welding requirements to ensure weld thickness, width uniform, which masks to look for hot metal and slag bath equidistance (2-3 mm)%; Arc welding rod length : different models and determined that the general requirements of arc length is stable, acid electrode generally 3-4 mm, 2-3 mm normally alkaline electrode%; Welding perspective : According to determine the thickness of two pieces of welding, welding angle has two aspects : First, the angle between the direction of the rod and welding of 60-75 ; The second is the angle between two electrodes and welding around, the same thickness as welding, welding and welding pieces incident angle of 45 ; When the thickness ranging from welding, welding electrode and thick and thin pieces of welding electrode side angle greater than the angle between the side pieces; Arc : admission to the end of each weld should be filled crater, in the direction opposite to the direction of the back-arc welding, arc welding unchanged inside pit in 1974, to prevent the crater bite of meat.

对接焊缝及对接和角接组合焊缝，在焊缝两端设引弧板和引出板，必须在引弧板上引出后再焊到焊缝区，中途接头则应在焊缝接头前方15～20㎜处打火引弧，将焊件预热后再将焊条退回到焊缝起始处，把熔池填满到要求的厚度后，方可向前施焊；焊接速度：要求等速焊接，保证焊缝厚度、宽度均匀一致，从面罩内看熔池中铁水与熔渣保持等距离（2～3㎜）为宜；焊接电弧长度：根据焊条型号不同而确定，一般要求电弧长度稳定不变，酸性焊条一般为3～4㎜，碱性焊条一般为2～3㎜为宜；焊接角度：根据两焊件的厚度确定，焊接角度有两个方面，一是焊条与焊接前进方向的夹角为60～75 ；二是焊条与焊接左右夹角有两种情况，当焊件厚度相等时，焊件与焊件夹角为45 ；当焊件厚度不等时，焊条与较厚焊件一侧夹角应大于焊条与薄焊件一侧夹角；收弧：每条焊缝焊到末尾，应将弧坑填满后，往焊接方向相反的方向带弧，使弧坑甩在焊道貌岸然里边，以防弧坑咬肉。

The film is a true story that occurred in Hollywood in 1997 along the northern bank robbery, two robbers took the AK-47 bullet-proof vests, and their only holding a pistol against the police (special forces have not arrived) So a fierce gun battle began, many police officers and the public were injured, fortunately, although 20 were shot, but no police or civilian deaths, the only two deaths that the two culprits .

Inthis paper, a new method is presented, in which we measure the thickness ofsurface film layer by means of measuring the distance between correspondingtwo dark lines in two groups of white light interference fringes that are res-Pectively produced by two beam reflected by two surface of the thin filmlayer and another beam coming from another arm in Michelson interferome-t...
