THE ZnO powder (micro-crystallites), an important functional material, has a wide applica-tion in the fields of ceramics, coatings and electronic devices. However, the powder, usuallyobtained by calcination of zinc oxalate, has a wide particle-size distribution and poor sinteringactivities so various methods for its preparation have been developed. The hydrothermalmethod is widely used to prepare many superfine powders such as ZrO_2, BaTiO_3, PLZT, dueto many advantages compared with other methods. Recently, the powder of Ⅱ—Ⅵ com-pounds can also be prepared by this method. Furthermore, crystallite shapes may be consid-

世界著名钢琴家鲁宾斯坦说，评价一座城市，要看它拥有多少书店。 眼下，在读屏时代，电子化阅读如潮水一般，几乎将所有人裹挟其中，即使钟爱纸质书的人，也有相当一部分渐渐疏远了书店。人们还需要实体书店吗？ 或许，到这些书店走走看看，你就会有不同的发现和感受。 2017年1月14日下午，石家庄勒泰写字楼A座某房间。 午后的阳光透过落地窗洒满半间屋子，靠窗摆放的几对明黄色沙发更显温暖。六七位年轻人舒服
