Water temperature is one of the most important factors that affect the occurrence of harmful algal blooms(HABs).Characteristics of sea surface temperature(SST)variability related to a Noctiluca scintillans bloom were analyzed with Himawari-8 data in the Beibu Gulf during mid-February *** SST warming anomaly was found around the bloom area from 10:00 to 19:00 local time,with a peak temperature of 24.3℃at 15:00,which was 2.9℃higher than the surrounding normal sea *** possible formation mechanism of the HAB-induced SST anomaly was studied in this work by integrating meteorological,ocean dynamics,and ecological *** the HAB event,the sea surface was covered by biological mucilage.A model that considered the net heat flux,heat capacity,density of seawater,and temperature variation was established to estimate the thickness changes(ΔH)in the marine heating layer during the HAB *** model results show that the heating layer thickness of the HAB area(ΔH between 0.76 m and 0.91 m)was smaller than that of the non-HAB area(ΔH>1.19 m).The SST anomaly in this study might be caused by a thinner and warmer marine heating layer that is related to the biological mucilage on the surface of the HAB area.

基于星载含成孔径雷达(SAR)遥感影像,研究了浙江近岸海域风能资源的分布。利用2005-2011年443景ENVISATASAR影像反演了浙江沿海长时间序列高分辨率海面10m高度处的风场数据,风速反演采用CMOD4模式,风向信息来自全球再分析场资料NCEP-NCAR。基于所提取的风场数据,对浙江沿海风能资源进行了评估。利用研究海域浮标观测的风速数据对基于ENVISATASAR影像的风能资源评估结果进行了对比验证,结果显示,Weibull分布参数尺度因子A相对误差为1.59%,形状参数k相对误差为7.83%。对浙江沿海风能资源分布状况进行了研究,结果表明,浙江沿海风能资源极为丰富,该海域海面10m高度处的多年平均风速为5~10m/s,近岸海域50km范围内年平均风能密度达到100~300W/m^2,其南部海域风能资源最为丰富,年平均风能密度最大可达500W/m^2。浙江沿海风能资源的分布在季节上呈现"秋冬季资源量大,春夏季资源量小"的特征。

作者： Wang Rong lou Minxiu Zheng xiulin(Northwestern Polytechnical University, Xi’an, China, 710072)

A method of constant △K value is applied experimentally to investigatechemical short crack characteristics of GC-4 high-strength steel in 3.5%NaClsolution. Experimental results show that there is a critical point of crack geometry aon da / dN-a curve of the crack propagation at constant △K value. When the cracklength a < a , chemical short crack effect appears. The value of a is almost not af-fected by the loading frequency, stress ratio and △K level. The ratio of characteristiccrack propagation rate of chemical short cracks to that of long cracks is a weak func-tion of the loading frequency, stress ratio and △K level. Based on the analysis, the rela-tion between the short crack propagation rate and crack size is suggested.

目的:了解透析后病人性生活满意度,分析其影响因素,为提高血液透析女性患者性生活满意度与生活质量提供依据。方法:依据国际女性性功能评估量表(BISF-W)自行研究并设计性生活调研问卷,从我市两家综合性医院2012年2月至2014年2月血液净化科收治的女性患者中随机选取110例进行调查。结果:在调查问卷性生活满意度11个维度中,主动提出性活动项选择从不或偶尔有101例占91.8%,7个条目选择从未或偶尔的患者超过50%;在诸多影响因素中,精力、学历、身体耐力、年龄影响透析后女性患者的性生活满意度(P<0.05)。结论:透析后患者性满意度较差,需要针对年龄稍大、身体耐力差的患者进行针对性干预,同时需要开展透析后患者性生活健康指导与宣教。
