The results indicate that the Y5V dielectric powder prepared by MSS not only are homogeneous, excellent and intensive, but also is active, can be sintered 900~920℃and the dielectric properties are better than the columbite precursor method , can be applied with pure silver paste, the production cost of MLCC is able to reduced.

结果表明：熔盐法制备的Y5V电子瓷料粉体不仅颗粒均匀、形貌好、易分散，而且活性高，使得多层陶瓷电容器的烧结温度可以降低到900~920℃，其介电性能要优于传统的二步合成法制备的粉体，十分有利于采用全银内浆，大大降低MLCC的生产成本。

In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.

一般玻璃纤维增强管材在常规挤出时当添加的玻璃纤维体积含量小于临界体积分数(当添加的玻纤的复合体系拉伸强度等于基体聚合物材料的拉伸强度时的玻纤体积分数)时，玻纤起不到增强的作用，反而会使复合材料的整体强度降低；但在复合应力场下挤出时，当添加的玻纤含量小于临界体积分数时，复合体系的拉伸强度不但没有降低反而升高了；当添加的玻纤含量大于临界体积分数时，复合体系要达到同样强度，经过复合应力场的玻纤增强管材需要的体积分数小于理论值。

Comparison the in vivo activity of 90％EtOH fraction and compound 21 with estradiol, indicated the 90％EtOH fraction behaved the stronger activity on total mineral content, total density, trabecular mineral content, trabecular density and the anti-twist strength of the proximal tibia in OVX rat than estradiol, but compound 21 displayed the weaker activity on total mineral content, total mineral density, trabecular mineral density, cortical mineral content, cortical mineral density, cortical thickness and the anti-twist strength of the proximal tibia than estradiol.

通过90％乙醇部位及化合物21都与阳性对照药雌二醇的纵向比较后，在大鼠OVX模型中，90％乙醇部位高剂量组在提高全骨的骨矿含量和骨密度、松质骨的骨矿含量和骨密度及骨的抗扭力方面，作用强于阳性对照组雌激素类化合物，化合物21在小鼠OVX模型中，抑制了全骨的骨矿含量、骨密度和全骨断面面积的降低，松质骨骨密度的降低，皮质骨的外膜周长的增长，皮质骨骨矿含量量、皮质骨厚度和皮质骨密度的下降及抗扭力的减弱。

It was discovered that with increasing the doping level of Mn, pyroelectric coefficient, dielectric constant and dielectric loss decreased.

The preliminary results showed that the atmosphere contaminator mainly contained SO\-2, NO\-\%x\% and suspended granule. Which caused large area acid rain with high frequency. As pollution became more serious, there were decreases in pH value and increases in the content of SO\+\{2-\}\-4 and Al\+\{3+\} in forest soil; the chlorophyll concentration also would decrease...

初步结果表明：大气污染引起珠江三角洲地区发生大面积、高频率的酸雨，主要的污染物有SO2 、NOx、悬浮颗粒物等；随着污染程度的增大，森林土壤pH值降低，SO2 - 4和Al3+质量浓度增大；马尾松、湿地松叶片叶绿素含量降低，生长衰退甚至死亡；但不同树种对大气污染敏感程度不同，种植马占相思比马尾松更能增加林地对酸雨缓冲力和提高土壤肥力。

Our province is seriously affected by drugs, one of the provinces, registered 40,000 drug addicts, the province reported a total of AIDS due to intravenous drug users infected with HIV continued to increase in the proportion of methadone maintenance treatment alternative to reduce the drug addicts syringe sharing the risk of the spread of AIDS, drug users has also reduced the number of drug use and drug-seeking triggered by a variety of criminal activities.

我省是受毒品影响较重的省份之一，登记在册吸毒人员有4万，全省累计报告艾滋病感染者中因为静脉注射吸毒感染艾滋病的比例在不断提高，美沙酮替代维持治疗有效降低了吸毒人员共用注射器传播艾滋病的几率，也降低了吸毒人员使用毒品的数量和因寻找毒品而引发的各种犯罪活动。

Days after a convulsant dose of KA, the seizure susceptibility were found in KA+NS group and enhanced in KA+PL017 group, whereas significantly decreased in KA+β-FNA group (p.01).β-FNA prolonged the latency and reduced the stage of seizures in dose-dependent manner.

结果显示，一次给予惊厥剂量KA后7天，KA+NS组的癫癎发作敏感性形成；MORs激动剂组（KA+PL017）动物出现癫癎发作敏感性增强；与上述两组比较，MORs拮抗剂组动物癫癎发作敏感性明显降低（p.01），β-FNA以剂量依赖方式延长癫癎发作的潜伏期、降低发作级别。
