This research was important to understand the symmetry property on Dauphine and Brazil twinning of α-quartz and provided a useful method for the identification of the two kinds of twinning.

这一研究对认清α-石英道芬双晶和巴西双晶腐蚀像的对称关系，鉴定α-石英的双晶类型具有理论与实际意义。

There are α-β change apex in the decrepitation curve from auriferous quartz vein and Au-bearing altered fracturing zone orebodies.

蚀变岩型矿体石英爆裂曲线不出现α-β转变峰，反映其形成温度低于石英转变峰的温度，应与侵入岩浆无明显密切关系。

The studies on mineralogy, fluid inclusions, and decrepitation temperature indicate that the gold deposit was formed by mixing of two kinds of fluids from different origins, instead of by gradual evolution of a single fluid.

石英脉型矿体主要与花岗岩浆热液关系密切，蚀变岩型矿体主要与深源流体有关，在矿体浅部它们强烈的挤压复合部位形成明金富矿体石英脉。

The new technique determines the absorbed intensity instead of the absorbance as conventionaly was. The absorbed intensity is measured for a capillary cell (i. d. 50μm) and a decussate optical super-thin cell (40μm) for serial KMnO~4 solutions.

在内径50μm的石英毛细管超薄池以及由石英光导纤维构成的十字交叉超薄光学吸收池上，分别测量了系列高锰酸钾溶液吸收光强。

Light output analysis tests character of spectrum radiate of pyrotechnic mixtures and analyses wave band distribute of light by comparing different static blaze spectrograms of the pyrotechnic mixtures. Screen out the better pyrotechnic mixtures according to request of pumping source. Press experiments in airtight erupt container experiment, which simulate the circumstance that pyrotechnic mixtures deflagrate in quartz pipe, realize the press influence to the quartz pipe wall and the disciplinarian of axes press variety. Apply these pyrotechnic mixtures to Nd:YAG lasers as the pumping source and compare pumping efficiency of different pyrotechnic mixtures. Pumping efficiency is an important standard which checkout if these pyrotechnic mixtures are the better pumping source. Sensitivity experiment analysis incarnate security of pyrotechnic mixtures that is the essential parameter in the process of design, manufacture and use.
