通过对中国大陆除新疆和东北深震区以外的主要地区2000年以来5级以上地震活动特征的研究发现,5级以上地震近源区的相继发震是某些区域地震活动的重要特征。依据这一特征可以对今后研究区内5级以上地震的后续地震作中期预测。  相似文献   

Hydrology, circulation and distribution of particulate matter in Thermaikos Gulf (NW Aegean Sea), during September 2001–October 2001 and February 2002

The hydrography, circulation and distribution of particulate matter in Thermaikos Gulf (NW Aegean Sea) are described, for September 2001 and October 2001 and February 2002. The observations were obtained to assess the impact of anthropogenic and natural resuspension processes on the coastal ecosystem. The first two periods represent highly stratified conditions and mild weather conditions; in September trawling is prohibited, whilst the October cruise took place following the commencement of the activity. The sampling in February was undertaken to record the contribution of natural resuspension to the system, in a stormy period.The water circulation was mainly baroclinic during autumn and barotropic in winter; this was due to vertical homogenisation of the water column, during the latter period. The distribution of the bottom nepheloid layer (BNL) was very different in the winter than in the autumn.Microstructure measurements were undertaken, which allowed the vertical eddy diffusivity to be estimated, together with the near-bed shear stresses. Computation of the diffusive flux of particulate matter (PM), from the BNL into the intermediate water column in response to turbulent motions, reveals that the PM flux was much higher in October than in September; this is despite the fact that the friction velocities were similar. This observation could explain partly the observed higher PM concentrations (PMC) in the intermediate layer, in October. Likewise suggest that the higher PMC in October could be attributed to trawling. The limited shear stress and friction velocity values obtained during the September and October cruises were always low; these were possibly capable of resuspending only recently deposited, “fluffy” material. Thus, the observed nepheloid layers are likely to be maintained by advection from the shallow water regions and trawled areas.  相似文献

黄彩依  欧阳雅蓉  傅威武 《应用海洋学学报》2020,36(8):14

目的：观察三香通络饮联合苯磺酸氨氯地平片治疗老年性高血压病的临床疗效。方法：将92 例老年性高血压病患者按随机数字表法分为治疗组和对照组,每组各46 例。对照组口服苯磺酸氨氯地平片治疗,治疗组在对照组基础上加用三香通络饮治疗。比较2组的综合疗效、中医证候积分及不良反应发生情况。结果：总有效率治疗组为89.13%（41/46）,对照组为60.87%（28/46）,2组比较,差异有统计学意义（P<0.05）;2组各项中医证候积分治疗前后组内比较,差异均有统计学意义（P<0.05）,且治疗后头晕目眩、头痛、心悸、口干口苦评分组间比较,差异均有统计学意义（P<0.05）;不良反应发生率治疗组为10.87%（5/46）,对照组为19.57%（9/46）,2组比较,差异无统计学意义（P>0.05）。结论：三香通络饮联合苯磺酸氨氯地平片治疗老年性高血压病患者的临床疗效优于单用西药治疗,且能有效减轻临床症状,值得推广。  相似文献

目的：探讨健脾柔肝息风汤对抽动障碍模型大鼠运动性抽动的调节机制,为临床治疗抽动障碍提供实验依据。方法：将60只SD大鼠随机分为空白组,模型组,氟哌啶醇组,健脾柔肝息风汤低、中、高剂量组,每组各10只,除空白组外各组大鼠连续7 d腹腔注射亚氨基二丙腈（IDPN）造模,造模成功后连续灌胃6周,灌胃后第1、3、6周分别观察大鼠的行为学改变,采用RT-PCR法检测大鼠脑组织DRD1 mRNA、DRD2 mRNA含量。结果：灌胃6周后,与模型组比较,健脾柔肝息风汤中、高剂量组及氟哌啶醇组在运动行为评分、刻板行为评分及DRD1 mRNA含量方面均有所下降（P<0.05）;而健脾柔肝息风汤低、中、高剂量组及氟哌啶醇组在DRD2 mRNA含量方面有所下降（P<0.05）。结论：健脾柔肝息风汤可通过降低TD模型大鼠脑组织多巴胺DRD1 mRNA、DRD2 mRNA的含量,而改善TD模型大鼠运动性抽动行为。  相似文献
