轴对称辐射传递逆问题的三种求解算法比较

针对轴对称光学薄火焰,用图像探测器和滤色片获得火焰的单色辐射图像,根据火焰的单色辐射强度,分别采用最小二乘法、正则化方法和线性规划法对辐射传递逆问题进行了求解.对一个轴对称乙烯扩散火焰进行实验检测,通过对三种求解方法的结果比较,表明对辐射强度较高的火焰中部和上部区域,三种方法均可获得较好的重建结果;而对于辐射强度较低的火焰下部区域,由于线性规划法同时具有光滑性和约束性的优点,可以获得较好重建结果,它对求解轴对称辐射传递逆问题是一种比较理想的算法.

高效液相色谱法测定复方盐酸普莫卡因乳膏含量

目的建立高效液相色谱法(HPLC)测定复方盐酸普莫卡因乳膏含量的方法。方法选用CLC-ODS C18色谱柱(150 mm×4.6 mm,5μm),流动相为乙腈-磷酸盐缓冲液(55∶45,体积比)调节pH值为7.5,流速为1.0 mL/min,柱温为40℃,检测波长为224 nm。结果盐酸普莫卡因在0.212 0~0.903 5 mg/mL范围内浓度与峰面积呈良好线性关系(r=0.999 9),平均回收率为99.63%,RSD为0.53%。结论该法简便、快速、可靠,可用于复方盐酸普莫卡因乳膏的质量控制。

略论“ちょっヒ”所反映的日本文化

通过对“ちょっヒ”四种用法的考察，可以发现“ちょっヒ”的比较标准由客观存在的事物转向了主观判断，其客观性逐渐减弱，主观性逐渐加强。这些变化反映了日本人中考虑对方心理感受的文化心理。

Research on consistency measurement and weight estimation approach of hybrid uncertain comparison matrix

The consistency measurement and weight estimation approach of the hybrid uncertain comparison matrix in the analytic hierarchy process （AHP） are studied. First, the decision-making satisfaction membership function is defined based on the decision making＇s allowable error. Then, the weight model based on the maximal satisfactory consistency idea is suggested, and the consistency index is put forward. Moreover, the weight distributing value model is developed to solve the decision making misleading problem since the multioptimization solutions in the former model. Finally, the weights are ranked based on the possibility degree approach to obtain the ultimate order.     

Homology Priority Task Scheduling in μC/OS-Ⅱ Real-Time Kernel

μC/OS-Ⅱ is an open source real-time kernel adopting priority preemptive schedule strategy. Aiming at the problem of μC/OS-Ⅱ failing to support homology priority tasks scheduling, an approach for solution is proposed. The basic idea is adding round-robin scheduling strategy in its original scheduler in order to schedule homology priority tasks through time slice roundrobin. Implementation approach is given in detail. Firstly, the Task Control Block （TCB） is extended. And then, a new priority index table is created, in which each index pointer points to a set of homology priority tasks. Eventually, on the basis of reconstructing μC/OS-Ⅱ real-time kernel, task scheduling module is rewritten. Otherwise, schedulability of homology task supported by modified kernel had been analyzed, and deadline formula of created homology tasks is given. By theoretical analysis and experiment verification, the modified kernel can support homology priority tasks scheduling, meanwhile, it also remains preemptive property of original μC/OS-Ⅱ.
