The Nanping granitic pegmatite is one of the most important rare-metal deposits in China. In this pegmatite field the No. 31 granitic pegmatite is the most highly evolved and well mineralized one, where beryl is the most important beryllium mineral.

福建南平花岗伟晶岩是中国重要的稀有金属花岗伟晶岩之一，其中31号脉是分异程度最高、稀有金属成矿作用最重要的岩脉，绿柱石是其中最主要的铍矿物。

Alkaline earth metal Any of the six chemical elements in the second leftmost group of the periodic table (beryllium, magnesium, calcium, strontium, barium, and radium).

碱土金属：碱土金属是元素周期表中的IIa族元素，即铍、镁、钙、锶、钡、镭。

Experimental results indicate that the polar radius of the long spherical hollow Be rotor is 0.52 μm longer than equator radius,which is well coincident with the design value of 0.54 μm.

实验结果表明：该加工后的长球形空心铍转子的极点半径比赤道半径长0.52 μm，与设计值0.54 μm相吻合。

The acute symptoms of contact of beryllium with the mucous membrane of the eye and upper respiratory tract include itch , and rhinorrhea

眼睛粘膜和上呼吸道粘膜若接触铍，其急性症状是发痒、灼烧和流鼻涕。

Its main components are alumina and berillia and rhombic system.

It does not occur uncombined in nature but is found chiefly as the mineral beryl (of which emerald and aquamarine are gemstone varieties).

自然界不存在单质铍，主要存在于矿物绿柱石(其中祖母绿和海蓝宝石都是宝石型变种)中。

The experiment result shows that the designed cooling structure of beryllium beam pipe is reliable and the optimal velocity satisfies the requirement of cooling.

实验测量结果表明，束流铍管冷却结构设计合理，最佳流速满足冷却要求。

In order to do this, the width of narrow annuli cooling channel of beryllium beam pipe was designed by optimization method, the theoretical analysis and finite element method were used, then the optimal width was chosen, the influence of concentrated heat on the temperature of inner and outer wall was studied, and the optimal working velocity of cooling fluid was given.
