重名、异名、无名是中药方剂整理的首要难点

重名，即指同名异方；异名，指一方多名；无名，即没有正式方名。在大量的中药方剂中，重名、异名相当普遍：大量的方书中，还有大约百分之几到百分之九十左右不等的方剂无名。方剂整理和方剂名词审定都有困难，应该引起重视。     

Scientific patronage in the age of Darwin: The curious case of William Boyd Dawkins

This essay examines the curious relationship between Charles Darwin and the palaeontologist William Boyd Dawkins (1837–1929). Dawkins was a beneficiary of Darwin's patronage and styled himself as a Darwinian to Darwin and the public, yet viciously attacked Darwin and his theory in anonymous reviews. This has confused historians who have misunderstood the exact nature of Dawkins's attitude towards evolution and his relationship to Darwin. The present study explains both the reasons for Dawkins's contradictory statements and his relationship with Darwin. I introduce Batesian mimicry as a conceptual framework to make sense of Dawkins's actions, suggesting that Dawkins mimicked a Darwinian persona in order to secure advancement in the world of Victorian science. Dawkins's pro-Darwinian stance, therefore, was a façade, an act of mimicry. I argue that Dawkins exploited Darwin for his patronage – which took the form of advice, support from Darwin's well-placed friends, and monetary assistance – while safely expressing his dissent from Darwinian orthodoxy in the form of anonymous reviews. This is, therefore, a case study in how scientific authority and power could be gained and maintained in Victorian science by professing allegiance to Darwin and Darwinism.     

一种基于果蝇优化方法的连续查询攻击算法

针对位置信息服务的隐私保护轨迹安全隐患,在已有研究的基础上提出了一种新的连续查询攻击算法(Continuous Queries Attacking algorithms based on Fruit Fly,CQAFF).首先该算法结合熵和查询匿名度量定义了查询识别率的计算模型,并利用果蝇优化方法给出了模型的求解流程.最后,利用移动对象数据生成器来进行实验,深入研究了影响CQAFF算法的关键因素,同时对比分析了该算法与其它算法的性能差异,结果表明CQAFF算法的有效性.
