3.Results showed: the average ionic energy of NaCl crystal decreased with crystal size; When the crystal was large enough, the average ionic energy reach a value 1 74732496, which was reported as Madelung constant.
结果表明 :NaCl晶体的平均离子势能随晶体增大而变低 ,晶体足够大时趋于恒定值 1 74732 496 ,此即NaCl晶体的Madelung (马德隆 )常数收藏指正
4.Large size and high quality BiB3O6(BIBO) crystal was grown with [110]or [111] orientated seeds by using top see-ded solution growth method. The crystal size is 30 mm×30 mm×40 mm, and the mass of the crystal is up to about 100 g.

5.The result indicated that the crystal of nano-TiO2 was anatase structure. The composite particle was nanometer and its crystal size was 4.2-2.5 nm. The crystal size of TiO2 was smaller with the increase of CNT content in the composite catalysts, showing that there was strong interaction between CNT and TiO2.
本文采用以钛酸丁酯为原料的酸性溶胶法制得TiO2-CNT复合体．XRD及TEM表征结果可知:TiO2-CNT 复合体中,复合微粒为纳米晶,其中TiO2的晶型呈锐钛矿型．晶粒尺寸随TiO2与CNT比例不同,在4．2～2．5 nm之间,即CNT比例越大,TiO2晶粒越小,表明TiO2与CNT之间存在强相互作用．收藏指正
6.With additives,the conversion rate of cBN,crystal size as well as the color are improved obviously. When the content of additive is 0 ~ 4 wt %,the conversion rate of cBN rises,the crystal size become larger,and the crystal color goes to amber gradually. When the content of additive is 5 ~ 8 wt %,there are some brown and black crystals in the obtained cBN crystals,the experimental repetition rate is low.
加入添加剂后,随添加剂加入比例的改变,cBN的转化率、粒度和颜色都有很大的变化,添加剂占实验样品重量百分比为0~4%时,cBN晶体转化率逐渐提高,晶体粒度逐渐增大,晶体颜色变深,当添加剂的重量百分比加大至5%~8%时,出现部分深棕色至黑色的cBN晶体,合成实验重复率降低。收藏指正
7.With the polycrystal,PbI_2 single crystal with size of ?15mm×30mm has been grown by vertical Bridgman method.
