The tongs all passes in the machine the gearing on the bed what tongs the gearing on realizes with superficial contact in the cowgirl on the bed in machine or matches.when the tongs installs in the machine bed work on the stage,the center of gravity of the tongs should be as far as possible low,center of gravity the more high an accepts should the dint is more big,the tongs bottom four directions should bulge,make its contact good,or the bottom establishes four a feets.when the tongs installs on the machine bed principal axis,the tongs install the to should have the enough match accuracy with principal axis cowgirl surface,and guarantee the gearing the stability dependable.

夹具体在机床上的安装都是通过夹具体上的安装基面与机床上的相应表面的接触或配合实现的。当物流设备需要的公司体在机床工作台上安装时，夹具的服装厂应尽量低，重心越高则支承面应力越大，夹具底面四边应凸出，使其接触良好，或底部设置四个支脚。当夹具体在机床主轴上安装时，夹具安装基面与主轴相应表面应有足够的配合精度，并保证安装稳定可靠。

The copper atom is in a planar coordination site of [N_2O_2] and it devites from the mean plane by only 0.80 pm. Byπ-πstacking interactions, a alabastrine structure was obtained.(2)Schiff-base complex [Cu(H_2O)]·H_2O, where H3GS is the 3-carboxyl -salicylidene glycine, was synthesized and characterized by elemental analysis, IR spectra and single-crystal analysis. The crystal belongs to monoclinic system, space group P2(1)/c, a=848.46(3)pm, b=681.54(3)pm, c=1967.16(8)pm,β=95.8210(10)°, Z=4, R_1=0.0279, wR_2=0.0724. The copper atom is in a square-pyramidal field with the base

结果表明该晶系属单斜晶系，空间群P2(1)/c，晶胞参数：a=848.46(3)pm，b=681.54(3)pm，c=1967.16(8)pm，α=90°，β=95.8210(10)°，γ=90°，Z=4，R_1=0.0279，wR_2=0.0724，Cu原子位于轻微变形的四方锥场底心，底面被氮原子、酚氧原子、甘氨酸羧基的一个氧原子和一个水分子氧原子占据，而甘氨酸羧基的另一个氧原子占据相邻分子的锥顶，因而形成一维链状结构；合成了单核双聚配合物Na_2[Cu_2_2]·2H_2O ，铜三核配合物Cu_3_2·5H_2O和铜锌异三核配合物ZnCu_2_2·5H_2O，并用元素分析，IR光谱，电子光谱和磁化率测定对配合物的组

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，因此薄膜中的晶粒生长除像整体材料中的晶粒生长一样考虑晶界能外，还需要考虑表面能和界面能，因为各向异性的表面能和界面能将导致薄膜中的异常晶粒生长和织构变化。
