BACKGROUND: Glass ionomer cement has been a commonly used filling material in the clinic. However, glass ionomer easily absorbs water and dissolves in early concretionary phase, which can reduce the leak tightness of the edge of obturator, resulting in slightly leakage.

背景：玻璃离子水门汀目前已发展成为临床常用的充填材料，但玻璃离子在凝固的初期易吸水溶解的特性，会使充填体边缘密封性减低，产生微渗漏。

In 1977, convicted Watergate conspirator G. Gordon Liddy was released from prison after more than four years.

Methods 20 human biscuspids scheduled to be extracted for the orthodontic reasons were prepared for porcelain fused to matal crown,of which every 2 teeth were from the same patient and the same jaw. The teeth were randomly, blindly and selfcontrolly divided into 2 groups.In the control group:the temporary crowns were cemented with zinc oxide cement.In the testing group:Green Or was applied before the temporary crowns were cemented with zinc oxide cement.

要领 选择因正畸治疗必要而打算撤废的20颗前磨牙举办金属烤瓷全冠牙体准备，其中每2颗牙均为同颌同名牙；授与随机、双盲、自身比较计划分为2组：比较组在牙准备体上直接用氧化锌丁喷香酚水门汀粘固且则冠；不雅察看组在牙准备体上涂布极固宁TM后用氧化锌丁喷香酚水门汀粘固且则冠。

选择因正畸治疗需要而计划拔除的20颗前磨牙进行金属烤瓷全冠牙体预备，其中每2颗牙均为同颌同名牙；采用随机、双盲、自身对照设计分为2组：对照组在牙预备体上直接用氧化锌丁香酚水门汀粘固暂时冠；观察组在牙预备体上涂布极固宁TM后用氧化锌丁香酚水门汀粘固暂时冠。

Objective:To choose the children repaired the caries with general and atraumatic restorative treatment,and to evaluate the effect.Methods:A total of 184 caries of 78 patients were randomly divided into two groups,the general and the ART group,with FXⅡ glass ionomer cement filling,and the clinical evaluation was observed after 1 year and 2 year.

目的：选择适合儿童进行常规和非创伤性充填术技术，评价常规和ART技术采用FXⅡ玻璃离子水门汀修复龋损的效果方法：78例184颗乳牙龋洞，随机分成两组，分别应用常规和ART技术，用FXⅡ玻璃离子水门汀充填窝洞，1年及2年后随诊充填情况。

Objective: To study the effect of molecular weights of compolymer and sinter temperature of powder on the properties of zinc polycarboxylic cement.

目的：研究聚羧酸锌水门汀液剂中共聚物分子量及粉体烧结温度对水门汀性能的影响。

Results: With zinc polycarboxylic cement molecular weights and sintering temperature of powder in creasing.

结果：水门汀压缩强度和对牙釉质的剪切粘接强度随共聚物分子量增加而增加，但当共聚物分子量增加到5.2×10^4了以后，水门汀就不能使用。

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

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。
