We have studied quantum statistical properties of the exciton in a leaky quasi-mode cavity. It is shown that when the exciton is initially in a squeezed coherent state whereas cavity initially in a vacuum state, there is energy exchange between the exciton and cavity. Both the exciton and cavity may exhibit sub-Poissonian distribution and exist quadrature squeezing. Calculation shows that correlation between the exciton and cavity is classical, which implies that there is not the violation of the Cauchy-Schwartz inequality.

Interference between the two Bose-Einstein condensates with collision and dissipation is investigated. Itis found that when the two condensates are initially in the coherent state, the interference intensity is affected by thecollision and dissipation, but for the initial Fock state, it is only related to the dissipation. Whether the initial stateis in the coherent state or in a Fock state, the fidelity time has nothing to do with collision. For the initial coherentstate, the fidelity loss rate is zero, but for the initial Fock state, it is determined by the initial particle number of thetwo condensates and dissipation.

何首乌作为药物,始载于宋代《开宝本草》,为传统的补益类药材。近年来,何首乌的肝毒性引起了国内外学者的高度关注。该文对历代本草著作中的何首乌药图进行了考证,并对影响何首乌的品质及毒性因素进行了本草学考察。历代本草中收载的何首乌图基本上均为蓼科植物何首乌Polygonum multiflorum,仅《太乙仙制本草药性大全》和《圖解本草》中的附图可能分别为蓼科植物翼蓼Pteroxygonum giraldii和薯蓣科植物黄独Dioscorea bulbifera。历代本草著作中何首乌图与萝藦科鹅绒藤属植物相差甚远。唐代《何首乌传》中已经注意到何首乌块根中的异常维管束,该特征被历代本草所沿承,这也是推断其基原为蓼科植物何首乌的证据之一。历代本草中对异常维管束性状的描述逐渐形成了"云锦花纹"这一术语,并认为"五瓣者良"。此外,古代医药学家已经注意到不同性状的何首乌存在毒性有无之别,即"体润而嫩大者佳""老硬多筋,服之塞血"。该文梳理了历代本草中何首乌种质及其"辨状论质"观,为开展何首乌质量评价研究提供了本草学依据。
