沂沭断裂带垂直形变与断层活动特征分析

利用跨断层短水准资料分析了沂沭断裂带断层活动特征，结果表明：NNE向的沂沭断裂带与NW向断裂活动性质有所不同，沂沭断裂带主要为压性逆断活动，北西向断裂带为张性正断活动，与地质考察结果基本一致。此外，沂沭断裂带及北西向断裂带都具有分段活动的特点。     

Thin electron beam propagation in plasmas

The propagation of dense electron beams and the interaction with the ambient plasmas are studied by using two-dimensional electrostatic simulations. When the width of the beam is of the order of electron gyro-radius, the beam electrons move across the magnetic field lines and the beam-plasma interaction becomes prominent with the reduced beam density. When the width of the beam is of the order of ion gyro-radius, the propagation of beam electrons is possible only with the formation of the ion channel. However, since the time scale of the ionic motion is much longer than that of the electronic motion, most of the beam electrons return back to the original beam injection region

Spatiotemporal variations of internal P-loading and the related mechanisms in the large shallow Lake Chaohu

Spatiotemporal variations of P species and adsorption behavior in water column, interstitial water, and sediments were investigated in the large shallow eutrophic Lake Chaohu. Orthophosphate (Ortho-P) and total phosphorus (TP) concentrations were significantly higher in the western part than in the eastern part of the lake, due to different nutrient inputs from the surrounding rivers. Moreover, particulate phosphorus (PP) concentration was in a similar spatial pattern to Ortho-P and TP concentrations, and also showed significantly positive correlation with the biomass of Microcystis, indicating more uptake and store of phosphorus by Microcystis than by other algae. Increase of pH and intensive utilization of P by phytoplankton were the main factors promoting P (especially Fe-P) release from the sediment to interstitial water during the cyanobacterial blooms in Lake Chaohu. Spatial dynamics in TP concentration, P species and adsorption behavior of the sediment, coupled with the statistical analyses, suggested that the spatial heterogeneity of P contents in the sediment was influenced by various factors, e.g. human activities, soil geochemistry and mineral composition. In spite of similar TP contents in the sediments, increase in proportion of Fe-P concentration in the sediment may result in a high risk of P release.

中医序贯疗法对PICU喘息性肺炎患儿的临床疗效及IgE的影响

目的：观察中医序贯疗法治疗儿童重症监护室（PICU）喘息性肺炎的临床疗效及对IgE水平的影响。方法：将60 例PICU喘息性肺炎患儿随机分为治疗组和对照组,每组各30 例。对照组采用西医常规治疗,疗程为14d;治疗组在对照组基础上采用中医序贯疗法,第1～7天服用小青龙汤治疗,第8～14天服用六君子汤加味治疗。比较2组综合疗效、喘息消失时间、平均住院天数,治疗后第8天、15天及1个月血清IgE水平,随访6个月,比较2组复发率。结果：总有效率治疗组为93.3%（28/30）,对照组为76.7%（23/30）,2组比较,差异有统计学意义（P＜0.05）。2组IgE治疗后第8天、第15天、1个月组内比较,差异均有统计学意义（P＜0.01）,治疗后第15天、1个月组间比较,差异亦有统计学意义（P＜0.01）。2组喘息消失时间、平均住院天数、复发率比较,差异均有统计学意义（P＜0.01或P<0.05）。结论：中医序贯疗法能有效改善PICU喘息性肺炎患儿喘息症状,降低IgE水平,缩短住院时间,降低复发率,疗效显著。
