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。     

保障公民劳动就业权的里程碑

就业促进法这部法律属于经济法中的宏观经济调控法，把它放到宏观经济调控法的结构中看，仍有一些问题值得探讨和研究。     

范德华力：生物学家、化学家、工程师和物理学家手册

分子间的范德华力是十分微弱的，但可以说普遍的存在着，在很多体系中起着巨大的作用，在物理学、化学、生物学等学科中得到了广泛的研究。但怎样计算范德华力？如何考虑各种条件对范德华力的影响？     

神经网络在电磁场数值问题中的应用

针对目前电磁场数值处理中计算繁杂慢速和耗费资源过多的问题,本文提出了一种基于神经网络小波理论进行计算的新方法。文中着重介绍了利用小波变换神经网络的基本理论,结合电磁场数值计算的基本方法,推导变换进而得到一个通用公式和处理方法。在该方法中,神经网络学习内容少和数据处理简单,因此该方法具有计算速度快,占用资源少的优点,并有用硬件实现的前景。     

加强意识形态工作 巩固意识形态安全

在国内外综合因素的影响下,我国主流意识形态的指导地位存在安全隐患,因此加强意识形态工作,确保意识形态安全是摆在我们面前的一项重大而艰巨的任务。     

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.     

Effects of self evaluation on late ERP components

High-density event-related potentials (ERPs) were measured when participants were required to evaluate oneself, significant others (father and mother) and the most familiar public figures (Lei Feng and Jiang Qing) based on trait adjectives. There were three referential conditions and a non-referential control condition including self-evaluation (SE), significant other-evaluation (SOE), general other-evaluation (GOE), and semantic positivity-evaluation (SPE). The behavioral data showed that RTs to GOE condition were longer than the other three conditions. Scalp ERP analysis revealed that (1) SPE condition elicited a more negative N2 than SE condition, which was associated with inhibition of responses; (2) SE condition elicited a more positive P300 than SPE condition, which was an index of attention to self-relevant stimuli; (3) there was no difference on the amplitude and latency of P300 between SE and SOE conditions, which reflected that the concept of “self” included intimate others (e.g., father and mother) in Chinese culture.
