我校位于河北省承德市,处于环京的特殊地理区位,防范"三股势力"向校园渗透面临许多问题和挑战,而新疆少数民族学生是境外"三股势力"渗透、争夺的重点对象.在新疆少数民族学生管理上,存在"三股势力"认识上政治敏感度不够;渗透情况了解不够清楚、不够关注;教育工作人员一般不懂维语,不懂新疆历史文化、民族宗教知识;缺乏建章立制和必要的法制教育;网络监管和防范手段薄弱等问题.在长期的管理实践过程中,我们总结了不少经验教训,有效地防范了"三股势力"对新疆少数民族学生的渗透.

In order to confirm the tradition that bolting Saposhnikoviae Radix could not be used as medicine,the content of four chromone components in the cortex and wood of Saposhnikoviae Radix was analyzed by high performance liquid chromatography( HPLC),and the chemical fingerprints were established,12 common peaks were calibrated. The similarity analysis found that the similarity between batches was 0. 115-0. 995,it indicates that the cortex and wood of Saposhnikoviae Radix have certain differences. On this basis,systematic clustering analysis,principal component analysis and orthogonal partial least squares discriminant analysis were carried out with the content of four chromone components and whether they met the pharmacopoeia criteria as the original variables. The results showed that the content of the four components in the cortex of Saposhnikoviae Radix was much higher than that in the wood,and the four components detected were able to distinguish the cortex and the wood of Saposhnikoviae Radix. The results of the study reveal the tradition that bolting Saposhnikoviae Radix should not be used as medicine dut to decreased quality.

目的 通过对不同商品规格防风中多糖成分的含量测定,阐明不同商品规格防风多糖成分的差异,为防风药材商品规格的划分提供依据.方法 采用回流提取法对防风中多糖的成分进行提取,并对多糖进行进一步的纯化,采用苯酚-硫酸法显色,利用紫外吸光光度法在488nm下测其含量,采用聚类分析法(HCA)进一步分析其结果.结果 18批防风药材中多糖含量有明显差异,防风药材的多糖含量与其商品规格的划分相关性较差.结论 不同商品规格防风药材中多糖的含量不同,防风药材多糖的含量与商品规格的相关性不大,推断仅凭借防风多糖的含量不能作为商品规格划分的依据.

大学生校园贷问题越来越引起相关部门的重视.电商平台、P2P网络借贷、分期网络平台,贷款门槛低、手续简单、到账快,诱导大学生提前消费,引发严重的校园恶性事件.通过对高校校园贷的现状、分析产生的原因,并提出相应对策,以期促进高校校园平安、稳定.

曳引式电梯主要是依靠多根曳引绳的拉力在空中作垂直起落运行,一旦曳引绳发生断裂,将有可能造成人员伤亡、设备损坏等严重后果.当曳引式电梯钢丝绳发生断开或钢丝绳异常伸长导致的松动等危险状况时,应该有效阻止电梯在这类状况下运行,这直接关系到电梯的使用性能和乘客的生命财产安全.提出了一种新型曳引式电梯自动控制保护装置,并对其关键部件的强度和模态进行分析.
