数字现代性批判是对数字化生存时代人的生存危机进行科学诊断的有效形式。资本与数字技术联姻对资本主义现代社会进行的理性化重构建构了数字资本主义最具时代特征的现代性症候,马克思的现代性批判方法论包含着对数字资本主义现代性进行科学批判的有效形式。从数据资本权力切入数字资本主义现代性批判,就会发现数字资本主义呈现出理性工具化、技术拜物教、物性化和单向度的核心特性。数据资本权力是资本与技术理性统治逻辑合谋的产物,它与社会生产力以及生产方式直接关联,只有在对数据资本权力扩张进行合理规制的前提下不断推动社会生产力的发展,才是扬弃数字资本主义现代性危机的根本出路,这对当下中国的数字化转型具有重要现实启示。

＜正＞*** Pharmaceutically active compounds（PhACs） are investigated and reported widely all over world, especially in surface water and wastewater treatment plants. The special characterastics of these compounds, like "pseudo-persistence" and "side-effects"have led to increasing concern on their occurrences, migrations and ecological effects. Moreover, according to many previous studies,

1. Introduction About more than half of the drugs currently in use are chiral compounds and near 90%of the last ones are marketed as racemates consisting of an equimolar mixture of two enantiomers. Although they have the same chemical structure, most isomers of chiral drugs exhibit marked differences in biological activities such as pharmacology, toxicology, pharmacokinetics, metabolism etc. Degradation of chiral drugs in wastewater treatment plants (WWTPs) can be enantioselective and lead to enrichment of one of

＜正＞*** Sewage epidemiology is becoming a more and more valuable research field. In this way, drug abuse and other closely related human behavior can be studied. However, such novel approach has great potentials to correlate a wide range of environmental, social, and economic aspects to pharmaceutical micropollution. In this study, we measured 23 antibiotics in Beijing（China） downtown to explore the impacts of drug use habit. In this case, all the studied WWTPs are designed only to receive and treat domestic sewage.

在飞控系统设计中,现代非线性控制理论已逐步得到应用,其中逆系统方法的物理概念清晰,参数对应明确,无不确定性算法,容易结合传统经验,易于为工程人员接受。该文将该方法应用于多操纵面飞机的基本控制律设计,从工程应用出发,使用多层分离简化设计,改进了多操纵面的使用策略和分配方法,分析了工程实现中的参数获取。大迎角飞行和自动着陆仿真结果显示,控制律能够协调使用推力矢量和常规舵面,准确控制飞行姿态和航迹;在着陆时能利用大迎角飞行能力显著降低着地速度,缩短滑跑距离;在飞机质量、惯量大幅度变化时,也能准确地控制姿态和轨迹。

研究了少模光参量放大器(FMOPA)的串扰特性,详细描述了发生在少模光纤模式内和模式间的四波混频及其相位匹配条件。给出了少模光纤中与时间无关的非线性薛定谔传输方程,利用数值求解方法描述了FMOPA的模间串扰,并推导出相应的半解析解。首先,设计了一种新的光纤结构,能在C波段(1530~1565 nm)以20 nm带宽传输五个模式。然后,用COMSOL仿真软件获得不同模式的模场分布,并用Matlab软件计算了这些模式间的传播常数与非线性系数。最后,通过合理调整每个模式的传输功率,在150 m长的光纤上使不同模式间的最大差分增益减小到0.7 dB。实验结果表明,半解析解与数值求解方法得到的串扰结果一致性较高。
