Discussed the micromeritic characteristies of CS extracted powder and the FT-207 powder, inspected the excipient proportion, the wettibility, the drying temperature factors through prescription screening as well as the orthogonal test to determine granulation process.

考察了CS浸膏粉和FT-207的粉体学性质，通过处方筛选以及正交试验考察了辅料配比、润湿度、烘干温度3个因素，确定了制粒的工艺路线。

The barium-strontium titanyl oxalate precursor powder was prepared successfully by using the simple oxalate chemical coprecipitation method. The pyrolysis of BSTO at 905℃ in air produced barium-strontium titanate powder. BST powder was characterized with SEM, TEM, XRD and FT-IR, which revealed that the powder was spherical, highly pure, perovskite, and the average particle diameter was 36nm.

采用草酸盐化学共沉淀法制备了草酸氧钛锶钡前驱体，通过905℃高温煅烧，制得了高纯纳米钛酸锶钡，并利用SEM、TEM、FT-IR和XRD对其进行了表征；并将该粉体应用于水中重金属镉离子的吸附。

On the basis of the crystallography, however, systematic investigation on crystalline habit of oxide crystal synthesized by hydrothermal processing, including single crystals and crystalline grains in ultrafine ceramics powder, is also a noticeable subject with theoretical and applicable significance, which has been studied in this article according to plentiful data of experiments obtained in research on crystal defects in synthetic smoky quartz, preparation of amethyst quartz and ultrafine zirconia and alumina powder by hydrothermal processing.

但以结晶学为基础，较系统地研究水热条件下氧化物晶体，包括单晶和陶瓷微粉中的晶粒的结晶习性和结晶动力学仍是一个值得重视的、既有理论意义又有应用价值的课题。本文通过对水热法人工烟水晶中的缺陷、人工紫水晶的生长、水热法超细ZrO〓粉体和Al〓O〓粉体的制备等研究，以较为丰富的实验资料基础上，在这一方面进行了探讨。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
