Based on the observation of atomic force microscopy, the etching morphology of faces and sections with different crystallographic significance on α-quartz has been studied. The etching morphology on the natural crystal faces hexagonal prism faces (1010 and 01(average10, rhombohedron positive form face 10(average11, rhombohedron negative form face 01(average11 and the sections between any of the two crystal faces has been observed. It is shown that the etching pit on the same simple form has the same shape, while the orientation of the etching pits can be different. Different simple forms have different shapes of etching pits and the shapes of etching pits on positive form and negative form of the same simple form are also different.

通过对α-石英自然晶面六方柱面10(平均值10和01(平均值10、菱面体正形面10(平均值11与菱面体负形面01(平均值11、以及介于上述自然晶面之间的切面进行腐蚀形貌的观察研究发现，石英晶体同种单形的晶面腐蚀坑形态相同，但方位可以有变化，不同单形的晶面腐蚀坑形态不同；同一单形的正形与负形腐蚀坑形状不同；蚀坑形态能够反映晶体的对称性。

On the rhombohedron face {1011}, Dauphine twinning showed different shapes of etching pits between individuals, because rhombohedron positive form {1011} and negative form {0111} appeared on both sides of twin partition line, while Brazil twinning showed symmetry plane between the irregular triangle etching pits of individuals. On the trigonal prism section 11(average20, Dauphine twinning showed different shapes of etching pits between individuals, because trigonal prism positive form {1120} and negative form {2110} appeared on both sides of twin partition line, while Brazil twinning should show symmetry plane between the ellipse or quadrilateral etching pits of individuals, which was not observed.

菱面体{1010}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是菱面体正形、菱面体负形出露处，导致蚀坑形状不同；菱面体{1011}面上存在巴西双晶处，不规则三角形蚀坑形态的方位关系为对称面关系；三方柱切面{1120}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是三方柱正形、三方柱负形出露处，导致蚀坑形状不同；三方柱切面{1120}面上存在巴西双晶处，椭圆形或四边形蚀坑方位应为对称面关系，但实验中未见到。

Tang, tea sage Lu Yu's tea production has been to Shengzhou, his good friend Jiaoran of Shengzhou produces "SOME tea" highly appraise Song Sun appears high in the "quiet," also recorded sharp to dozens of tea products, tea Falls, Wulong tea is really tea, and the purple and production processes. baking Tea, Kun Cha, the small-Kun Cha, Luyuan tea, small pit tea Jiaokeng tea.

The growth and nucleation rates of〓 cleavage face of YbYAB crystal are all very fast, because so many growth steps and growth centers were formed within only 2～3 second at the temperature near the saturate point. No spiral growth steps can be found, so growth mechanism is twodimensional nucleation. When the flux temperature increases for only 0.5℃ above the saturate point, the spiral melting holes are formed. The transformation from growth morphologies to melting morphologies is very sensitive to the temperature. When the temperature increases another 1℃, the spiral melting holes transform into two-dimensional nucleation melting holes.

YbYAB的〓解理面的生长及成核速度都非常快，在比饱和点低0.5～1℃的温度下，当生长2～3秒钟时，可以看到许多生长中心与生长台阶的形成，在较宽的台阶上还可以看到二维核的形成，没有看到螺旋中心，说明生长机理是二维成核生长；当温度比饱和点高0.5℃时，在〓解理面上形成螺旋状熔坑，这表明形貌由生长到熔化的转变与温度的关系是非常敏感的；当温度比饱和点高1.5℃时，螺旋状熔坑转变为二维成核状熔坑。

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 ion concentrations were studied in both four snow pits on Hami Miaoergou FlatTopped Glacier and one snow pit on Haxilegen Glacier No.51 of Kuitun river in eastern Tianshan Mountain, and both snow pits were retrieved in 2004. The results show that the Ca2+, NO-3 and SO2-4, particularly Ca2+, are major ions in the snow of snow pits in both ablation and accumulation area and also in the ice of snow pits in accumulation area on Hami Miaoergou FlatTopped Glacier, where the relationships among major cation concentrations in snow of snow pits can be revealed by ion concentrations in the ice of snow pits, but the correlation between ion concentrations in the snow of snow pits and elevation is not obvious, which probably can be attributed to the narrow span of elevation and sparse snow pits on glacier. However, the good correlation between ion concentrations in the ice of snow pits and elevation indicates that the elution process weakened gradually with the elevation rise and temperature decrease.

对2004年获取的天山奎屯河哈希勒根51号冰川1个雪坑和哈密庙尔沟平顶冰川4个雪坑的离子浓度特征进行了研究，结果表明：Ca2+、NO-3和SO42-是哈密庙尔沟平顶冰川雪坑雪层和积累区雪坑底部冰中的主要离子（尤其是Ca2+），其雪层中的主要阳离子关系可在底部冰中得以较好的反映，但雪层中各离子浓度与海拔的相关性不明显，可能与海拔的跨度较小和挖取的雪坑较疏有关；雪坑底部冰中的离子浓度与海拔间明显的相关性说明淋融作用随着海拔升高、气温降低而逐渐减弱。

The morphologies of the CdZnTe etch pits developed by four etchants including Nakagawa, Everson, EAg1 and EAg2 solutions are studied. The results show that the etch pits of EAg2 etchant on the (111) B surface are flat-bottomed. And the etch pits of Everson etchant on (111) B include flat-bottomed pits and pyramidal pits with different slant directions, while the positions of pyramidal pits don′t move as the surface layer is continuously removed.
