提出了一种共享内存环境下的并行质量引导相位解缠算法。首先,分析了相邻相位点质量值计算的内在关系,采用行、列数组保存中间结果消除梯度的重复计算;然后,按行进行计算任务分配,简化相邻窗口内的行、列均值计算;最后,通过OpenMP指令实现计算任务分配,完成质量图的并行计算。对于质量引导过程内在的并行性进行了分析,但受限于重复的线程启动和退出时间开销,难以体现速度优势。对合成孔径雷达干涉(synthetic aperture radar interferometry,InSAR)和干涉合成孔径声纳(interferometric synthetic aperture sonar,INSAS)干涉相位图进行解缠实验,结果表明,所提方法提高了相位解缠效率,为在实时条件下进一步提高相位解缠精度奠定了基础。

The effects of thermal history on the rheological properties of partially hydrolyzed polyacrylamide/ sodium dodecyl sulfate complex aqueous solutions have been studied using both steady shear and dynamic temperature sweep characterizations. An abnormal rheological behavior was found that dynamic moduli of the aqueous solutions increased, while the viscosity decreased after thermal treatment, which could help to gain insight into the micro-phase evolution of the polymer/surfactant complex aqueous solutions and its dependence on temperature.

Cable-like Au@SiO2 Janus composite nanorods with PS and PEG grafting on both ends respectively are fabricated by skiving in combination of a post favorable modification. The cable-like Au@SiO2 composite nanofibers are synthesized in the channel of porous anodic aluminium oxide （AAO） membrane. After skiving, the corresponding composite nanorods are obtained. Following, PEG-SH and PS-SH are conjugated onto the two ends of the nanorods by a selective partial modification, respectively. Length and diameter of the Au@SiO2 Janus composite nanorods can be tuned controllably. It can be extended to fabricate a variety of different Janus nanorods with different compositions and microstructures.
