摘要：A dynamic quantitative theory and measurement of power or dominance structures are *** power structures are represented as directed networks.A graph somewhat similar to the Lorenz curve for inequality measurement is *** changes in the graph resulting from network dynamics are *** are operationalized in terms of added nodes and *** of dynamic aspects of networks is essential for potential applications in many fields such as business management,politics,and social *** such,we provide examples of a dominance structure in a directed,acyclic *** calculate the change in the D-measure,which is a measure expressing the degree of dominance in a network when nodes are added to an existing simple network.

摘要：分析了h指数功能扩展后在科学家个人科研绩效评价中的三个缺陷,即缺乏灵敏度,缺乏区分度,缺乏波动性。针对这些缺陷,提出了R指数和AR指数。R指数用于解决h指数的灵敏度和区分度的问题;AR指数用于解决h指数只升不降的问题。利用17位普赖斯奖得主的论文数量和被引频次数量进行了h指数、R指数和AR指数的测算。针对h指数与R指数或AR指数配伍使用后的双因素问题,设计了标准化(h,R)指数和等效(h,R)指数。实测数据证明R指数和AR指数是h指数功能扩展的补充指标。

摘要：使用化学吸收剂的吸收塔和脱吸塔广泛地用在气体治理操作中,例如天然气净化过程中除去 H2S 的操作以及为增加天然气的热值除去 CO2的操作。在这些过程中,溶质因与吸收剂化学反应而从气流中除去。化学反应比用物理吸收（此吸收剂不与溶质反应）发生的物理溶解会产生较高的传质速率和较大的吸收能力。
