查询词典 pentagonal

The projection angle of two B-edges of pentagonal prism has a great effect on the second optical parallelism; however, it cannot be measured during on line processing, which results in low qualification rate.

由于五角棱镜两B棱的投影夹角对第二光学平行差影响倍率较大且加工过程中无法测量该夹角，从而导致棱镜加工合格率较低。

However, when occurring in Mesozoic remelted granite, pyrite is featured mainly by high gold content in pentagonal dodecahedron and in its complex; low content in cubic pyrite; Au/Ag ratio between 1-2; both N and P types of pyrite present in most deposits and P type only in a few deposits.

产于中生代重熔花岗岩中时，黄铁矿以五角十二面体居多，五角十二面体及其聚形含金较高，立方体含金性较差；Au/Ag比值在1-2之间，As的含量较高(＞600×10〓)；Co、Ni的含量则较低，一般为10n×10〓；热电性以既有P型又有N型的P、N混合型为特征，少数金矿床表现为单一的P型。

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。
