Objective To find a simple and effective way to prevent enamel decalcification by guiding patients wearing fixed appliance to use fluoride mouth rinse.

目的 通过指导接受固定矫治器治疗的患者使用含氟漱口液，以期找到一种简便有效的方法来防治牙釉质脱矿，从而应用氟化物防治固定正畸治疗中的牙釉质脱矿。

Methods 40 selected patients treated with fixed appliance were randomly divided into two groups （n=20 each）, the fluoride mouth rinse test group and the placebo control group.The number of decalcified teeth and the severity of enamel decalcification were evaluated and compared after three months and after six months.

从正在接受固定正畸治疗的恒牙列患者中随机选择40例上前牙明确诊断为釉质脱矿的患者，随机分配到试验组和对照组，每组各20例，分别比较3个月后及6个月后牙釉质脱矿程度的变化。

Aiming at the questions such as low grinding concentration,thick fineness of iron ore concentrate and high grade of tailing caused by the wet pre-selecting process before grinding,through the check of the flow and the results of small-scale test,puts forward the improved measures such as increasing grinding concentration,adding demagnetizer,screening the undersize first then floating,etc.

针对磨前湿式预选工艺造成的磨矿浓度降低、铁精矿粒度变粗、尾矿品位偏高等问题，通过流程考查和小型试验研究，提出了提高磨矿浓度、加设脱磁器、对筛下物料进行先筛分后浮选等改进措施。

The drilling program of approximately 1200 to 1500 metres, will consist of a set of four inclined diamond drill holes to test and confirm the Bernard gold vein mineralization and another set of six vertical holes to test that portion of the detachment fault closest to the Bernard lower plate mineralization.

钻探计划的近1200至1500米，将包括一套四张倾向于钻石钻孔测试和确认伯纳德金脉矿化和另一套六洞，垂直测试，部分拆离断层最接近伯纳德较低板矿化。

Iron-based perovskite-type compounds modified by Cu, Zn, Ni were prepared through sol-gel process to investigate their catalytic activities of NO direct decomposition. XRD analysis reveals that the samples calcined at 750℃ are pure perovskite phase.

采用溶胶－凝胶方法合成了Cu，Zn，Ni改性的钙钛矿复合氧化物系列催化剂。X射线衍射分析表明，750℃焙烧的此类催化剂在掺杂范围内均具有钙钛矿基本结构。
