Through electron probe\'s analysis to the albite jade, union grinding sample thin slice under polarizing microscope observation as well as X powder crystal diffraction data analysis. Discovery like Chen zhenqiang and "System Gemology" said that secondary mineral for actinolite, green mudstone, epidote and quart.

通过对钠长石玉进行电子探针的分析，结合磨制的样品薄片在偏光显微镜下的观察以及X粉晶衍射数据分析，可知钠长石玉中的主要成分为钠长石，次要矿物为硬玉、角闪石、绿辉石、钠铬辉石；并未发现如陈振强等人以及《系统宝石学》中所说的次要矿物为阳起石、绿泥石、绿帘石、石英。

In view of these realistic questions, this article conducts system albite jade gemology research and clarifies to the albite jade part dim consciousness, makes some essential supplements to the jewelry jade\'s research.

针对这些现实题目，本文进行系统的钠长石玉宝石学研究，澄清对钠长石玉的部分模糊熟悉，对珠宝玉石的研究做一些必要补充。

Therefore, I on raise the question to Chen Zhenqiang and "System Gemology" about the albite jade chapter, and the opposite amphibole\'s subspecies have carried on the division.

因此，本人对陈振强以及《系统宝石学》上关于钠长石玉章节的钠长石玉的矿物组成以及组成矿物化学成分部分提出质疑，并对角闪石的亚种进行了划分。

The apophyllite crystals from Huangshi of Hubei Province and Punna of India are studied by means of conventional gemmological methods, EMPA and LRM, including the crystal characteristics, chemical compositions and inclusions.

以湖北黄石与印度浦那鱼眼石晶体为研究对象，采用宝石学常规仪器、电子探针、激光拉曼光谱仪对比分析了两者的晶体特征、化学成分和包裹体等。

In gemology, it is correct to call any Chrysoberyl that changes color Alexandrite.

在宝石学上，人们都可以把能变色金绿玉称之为亚历山大石。

Iolite, in gemology term is also known as Cordierite in mineralogy.

玛瑙，宝石学术语也被称为堇青石的矿物学。

The gemmological characteristics and spectra of a type of rock crystal containing tube like inclusion s appearing in market in recent years are studied.

对近年来在国内市场出现的一种含管状包裹体的水晶制品进行了详细的宝石学特征及谱学研究，获得的主要结论有：该类型水晶是以 Z( 0 0 0 1 )为种晶板、在 2 80～ 3 3 8°C的条件下合成的；富含包裹体的部分可能是合成过程早阶段的产品。

There have been a rapid development in the areas of the diamond resources prospecting, diamond mineralogy and diamond gemology .

在金刚石资源勘探、金刚石矿物学、金刚石宝石学研究等方面，都取得了很大的进展。

The study of the forms of hydrogen in diamonds not only enriched the contents of mantle mineralogy, material sciences and gemology, but also provided some important informations for dealing with some problems concerning the Earth's mantle and core.

对金刚石中氢的研究可以丰富地幔矿物学、宝石学及材料科学等的研究内容，并可为解决地幔乃至地核的许多疑难问题提供线索。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
