The results show that the fine-grained hypidiomorphic pyrite, with a crystal form of pentagonal dodecahedron, contains more Au than others. Since the areas yield pyrite with relatively lower contents of main components S and Fe, while a greater gross content of trace elements, such as Cu, Pb, Zn, Au, Ag, are closely associated with gold deposits, the authors propose that a middle-scale gold deposit might be found in Zhaojiapuzi area; and there is a remote possibility to find a large gold deposit in Shengjingao area, wih a prospect of finding a concomitant gold deposit.gold deposits;mineralogical.

结果表明以五角十二面体晶形为特征的半自形细粒状黄铁矿含金性较高；黄铁矿主成份S、Fe含量相对低，而黄铁矿中Cu、Pb、Zn、Au、Ag等微量元素总量相对高的黄铁矿分布区城与金矿化关系密切；提出赵家堡子地区具备找到一处中型以上金矿的前景，而在生金皋地区找到大型金矿床的可能性很小，但有望找到伴生金矿床。

Based on point explosion theory , the approximate analytical formulas of momentum coupling coefficient and impulse of cone and parabolic crafts are deduced. The results show that the total axial impact momentum for parabolic craft is larger than that of cone craft and it increases with the increase of half open angle.

以LSD/LSC波理论为基础建立了一个近似的理论解析模型，推导出圆锥形和抛物形飞行器获得的冲量及冲量耦合系数的近似解析表达式，公式表明冲量耦合系数随着半张角的增加而增加，同时抛物形飞行器要比圆锥形飞行器的动量汇聚效果好。

There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

新疆榆树沟麻粒岩地体中发育两类尖晶石：一类见于中、基性麻粒岩体中，其化学成分富 Al贫 Cr ，属铝尖晶石，镜下为深绿色，呈半自形至他形粒状，与其它变质矿物共生，表现为麻粒岩相的新生变质矿物；另一类发育在空间上与麻粒岩体紧密相邻的超镁铁质岩体中，为铬尖晶石，镜下为深褐红色，呈不规则粒状分布于橄榄石、斜方辉石和单斜辉石之间，为麻粒岩相变质过程中稳定的残余矿物。

The result indicate that: the electrodeposition of zinc on nickel and tungsten substrates involves instantaneous three-dimensional nucleation. The coating is the best when the current density is 4mA/cm2 and the temperature is 80 ℃. The coating by the method of the impulse electrodeposition is better than the direct current electrodeposition. Especially when f is 100Hz, ton/toff is 2/8 and J is 8mA/cm2, the coating is clean and uniformity. The crystal size is nearly 0.3μ m .
