Offline bias correction of numerical marine forecast products is an effective post-processing means to improve forecast accuracy. Two offline bias correction methods for sea surface temperature(SST) forecasts have been developed in this study: a backpropagation neural network(BPNN) algorithm, and a hybrid algorithm of empirical orthogonal function(EOF) analysis and BPNN(named EOF-BPNN). The performances of these two methods are validated using bias correction experiments implemented in the South China Sea(SCS), in which the target dataset is a six-year(2003–2008) daily mean time series of SST retrospective forecasts for one-day in advance, obtained from a regional ocean forecast and analysis system called the China Ocean Reanalysis(CORA),and the reference time series is the gridded satellite-based SST. The bias-correction results show that the two methods have similar good skills;however, the EOF-BPNN method is more than five times faster than the BPNN method. Before applying the bias correction, the basin-wide climatological error of the daily mean CORA SST retrospective forecasts in the SCS is up to-3°C;now, it is minimized substantially, falling within the error range(±0.5°C) of the satellite SST data.

热处理前对芳香聚酰胺反渗透膜进行溶剂活化(或称润洗)是一类提高膜透过性的手段.普遍认为,在热处理前溶剂活化的过程中,芳香聚酰胺层内残留的芳香聚酰胺低聚物将溶于溶剂且溶剂可溶胀重整聚酰胺层,因而膜结构与性能发生变化.然而,热处理前溶剂活化多使用非极性溶剂,这类溶剂与芳香聚酰胺的溶解度参数相差较大,对芳香聚酰胺层的溶胀与溶解作用均较弱,因此,热处理前溶剂活化引起的膜结构改变不能完全归因于非极性溶剂与膜的相互作用.近期有研究表明,芳香聚酰胺层内残留物可在水中溶出,推测热处理前溶剂活化可能通过影响残留物在水中的溶出而改变膜结构.基于此,进一步探究热处理前溶剂活化对膜结构的影响机制.对比了水浸泡前后的膜结构与性能,分析了活化膜与未活化膜在水中溶出物质的紫外-可见光谱,对比了未活化膜和活化膜的结构与性能.结果表明,热处理后芳香聚酰胺层内仍有大量易溶于水的亲水性残留物.热处理前利用正己烷对膜进行溶剂活化可除去未反应单体及低聚物,削弱热处理过程中聚酰胺层的进一步交联,加剧芳香聚酰胺层内亲水性残留物在水中的溶出.因此,活化后的膜分离层厚度、粗糙度和分离层内酰胺含量均降低,膜透过性提升.本工作完善了热处理前溶剂活化对膜结构的影响机制.

需求响应(DR)常态化的发展依赖于高可靠性的信息交互,尤其是在无线传输应用中。为了提升当前DR中可中断负荷控制的通信信道质量,设计了一种基于信噪比和信道增益的自适应空时预编码策略。所提策略结合DR通信需求,在提高信息传输可靠性的同时自适应规避编码引入的额外计算开销。首先,基于中国DR信息交互规范,结合实际信息传输和控制的频度要求,规定DR不同时段传输的通信服务等级。然后,引入可以优化提升信道增益且DR终端计算开销更低的Alamouti编码技术。在此基础上,利用自适应预编码机制的Alamouti编码策略优化信息传输质量。仿真实例验证了所提算法的有效性。
