But unexpectedly, a lot of units came out, and 11 and 1 o'clock were damaged.

不过没有想到的是，很多单位出来了，11和1点的分矿也被破坏。

The effects of initial concentration of methylorange ,pH value of solution, concentration of Cl~- and aerating oxygen or not on photocatalytic degradation rate of methylorange were investigated with anatase TiO_2 as catalyst under normal daylight lamp.

以锐钛矿型TiO2为光催化剂，以普通日光灯为激发光源，考察了甲基橙的初始浓度、溶液pH值、Cl-的浓度以及通氧与否等条件对甲基橙光催化降解速率的影响。

The incidence and severity of enamel decalcification in orthodontic treatment either in three groups or in the number of the patient's teeth of three groups were evaluated before and after treatment.

目的：了解用固定矫器治疗后的牙釉质脱矿的发生率及严重程度，并评价用75%NaF处理牙面和使用含氟牙膏后的结果。

To explore the effect of high fluoride and low protein on tooth development and clarify the mechanism of excessive tooth wear, and decalcification of incisors were researched by SEM.

为了探索高氟低蛋白对牙齿发育的影响，阐明牙齿过度磨损的机理，应用扫描电镜对第一、二切齿脱钙前的矿化及脱钙后的基质结构作了观察。

Objective To evaluate the most effective method of fluoride application to prevent decalcification of enamel before,during and after etching in orthodontic treatment.

目的探讨氟化物在正畸治疗中预防牙釉质脱矿的最佳使用方法。方法制备正畸拔除的前磨牙96颗，随机分成4组，分别为对照组及酸蚀前、中、后用氟组，粘结托槽后，将每个样本分别放入装有2ml酸性人工唾液的试管。

Objective: To find a simple and effective way to prevent enamel decalcification by guiding patients treated with fixed appliance to fluor protector NaF and brush teeth with fluoride toothpaste.

目的：了解用固定矫器治疗后的牙釉质脱矿的发生率及严重程度，并评价用75%NaF处理牙面和使用含氟牙膏后的结果。

Fluoride mouth rinse can effectively prevent and treat enamel decalcification in fixed-orthodontic treatment.

在固定正畸治疗中，含氟漱口液能有效防治牙釉质脱矿。

Fluoride toothpaste can effectively prevent enamel decalcification in fixed-orthodontic treatment.

在正畸治疗中配合使用氟化物处理牙面，可预防牙釉质脱矿的发生。

In addition, the very structure of the compounds mineralized confers a degree of protection by prevent- ing decomposer organisms or their exoenzymes from accessing the nutrients in them.

此外，该化合物的结构矿一定程度的保护原有的ing decomposer有机体或预防——他们的exoenzymes接触到营养。

The isogram of thickness and grade of the orebody suggests that theconnection line of the mineral concentration area is coinciding with thepitch direction of the orebody; and the appearing rate ofα—βpeak ofquartz decrepitation temperature has a distribution regulation, whichchanges from high to low with the depth of the orebody. This regulationsuggests that the deposit bellow the 180m bears a good prospectingperspective.

通过编制矿体厚度、品位等值线图，发现金矿化富集部位的连线同矿体的侧伏方向一致；研究发现石英矿物爆裂法测温的α—β相转变峰的出现率在矿体中具有一定的分布规律，从矿体浅部到深部α—β相转变峰出现率由高到低变化，据此规律预测矿床180m中段以下深部还具有很好的找矿前景。
