中文摘要：

利用温差水热法，在复杂的盐酸体系下，合成了不同形态的无色绿柱石晶体。晶体生长所用试剂Al（OH）3、BeO、HCl等均为分析纯，SiO2为高纯度的石英碎块，高压釜内溶剂填充度为40％～55％，晶体生长温度500～600℃，生长时间7～15d。通过电子探针、X射线衍射分析，合成绿柱石的成分与其理想成分接近，晶体结晶程度高；利用双圈反射测角仪和微分干涉显微镜的测试与观察，合成绿柱石为六方短柱状晶形，主要发育平行双面c{0001}、六方柱m{1010}、a{1120}以及六方双锥p{1011}等4种单形晶面，各单形晶面的微观形貌相对比较单一，平行双面只有六边形生长台阶，柱面上主要为平行c轴的平直条纹，在局部地方出现多边形生长台阶，六方双锥单形晶面上存在比较丰富的多边形生长锥和乳状生长丘。

英文摘要：

Beryl crystals can be synthesized by hydrothermal method in complicated hydrochloric acid system as mineralizers in the condition of filling 40% to 55% ,reaction temperature 500 to 600 ℃ and reaction time 7 to 15 d. The original materials Al（OH） 3, BeO, HCl et al. are all pure chemistry reagent, and the SiO2 is shivers of lustration quartz. The composition and structure of hydrothermal beryl crystal are introduced after tested by electron probe microanalysis and X-ray diffraction. The study focuses on the crystal morphology and surface microtopography of hydrothermal beryl crystals with double coil reflecting goniometer and differential interference microscope. The hydrothermal beryl crystals are short hexagonal prism with four single forms._ They are parallel twins c {0001 } ,hexagonal prism m{1010} and a {1120} and hexagonal double wimble p{1011}. There is only hexagon sidestep in c {0001 } ,and in cylinder m { 1010 } and a {1120}. There are many parallel stripes along c axis,and a few polygon sidestep can be seen. There are lots of polygon wimble and breast growth hillock in p {1011}.
