集宁地电观测系统故障检查及处理

对集宁2017年4月1日—5月31日地电阻率原始观测数据曲线常规分析发现,NS、EW测道数值差异明显,采用电测深曲线进行对比分析,发现2测道电阻率数值基本一致。在同场范围内,地电阻率与电测深曲线应同步变化。对集宁地电阻率布极区、观测环境、观测系统、装置系统进行系列检查、测试,发现NS测道导线线芯与导线铠导通,导线铠与避雷箱箱体接触导致线路漏电,造成数值出现误差。通过对外线路以及电极引线等进行优化改造,集宁地电阻率观测数据恢复正常。

舒肝解郁胶囊联合利培酮治疗老年精神分裂症伴失眠的疗效及对患者睡眠质量和认知能力的影响

目的:探究老年精神分裂症伴失眠采用利培酮与舒肝解郁胶囊治疗对认知功能及睡眠质量的影响。方法:选取2019年5月至2020年5月潮州市第三人民医院收治的老年精神分裂症伴失眠患者86例作为研究对象,按照不同治疗方法分为对照组(n=40)和观察组(n=46)。对照组采用利培酮治疗,观察组采用舒肝解郁胶囊联合利培酮治疗,比较2组睡眠质量及认知功能。结果:观察组睡眠质量明显优于对照组,差异有统计学意义(P<0.05);观察组认知能力各项评分均优于对照组,差异有统计学意义(均P<0.05)。结论:老年精神分裂症伴失眠采用利培酮与舒肝解郁胶囊治疗可提升预后及生命质量。

城市更新背景下的连片更新规划思路研究——以南沙区黄阁镇旧镇连片更新改造方案为例

新型城镇化背景下,可持续已经成为城市更新的发展趋势。从区域角度出发,通过连片城市更新规划,统筹优化城市用地,解决旧城镇配套不健全、交通不联通的问题,是可持续城市更新的重要内容。

The Conversion Relationship between the Local Earthquake Magnitude and Surface Wave Magnitude in the Inner Mongolia Digital Seismic Network

Using 116 earthquakes over M_L3.8 in the Inner Mongolia region from 2008 to 2015, the local earthquake magnitude M_L and surface wave magnitude M_S are remeasured. Based on norm linear regression(SR1 and SR2) and norm(OR) orthogonal regression method, we established the conversion relationship between M_L and M_S. The results were tested with Gaussian disturbance. The result shows that the orthogonal regression method(OR) result has the best fitting curve, and the conversion relation is M_S=0.96 M_L-0.10. The difference between our result and Guo Lücan's(M_S=1.13 M_L-1.08) may be caused by regional tectonic characteristics. M_(S Inner Mongolia) value is significantly higher than the M_(S empirical) value, with an average difference of 0.23, the difference distribution of empirical relation and the rectified relation is in the range of 0.2-0.3.
