The distribution and content differentiation of morusin in the cultivated species of mulberry by HPLC-DAD are described in this paper. The experimental results showed that morusin is present in all parts of the mulberry bush. The content of morusin was highest in root bark and second highest in branch bark. The difference in morusin content of 20 different species of cultivated mulberry branch bark was significant. The level of morusin was highest in the branch bark of cultivated mulberry No. 404, a tetraploid cultivar, and third in the Husang 32 cultivar of Morus multicaulis. The method used in this study for determining morusin content exhibited good repeatability (RSD 6.02%) and recovery (100.62%). Therefore, the results from this study provide reliable data, for research and development in the future, on the level and distribution of morusin in mulberry in general and the differences found between various cultivated mulberries in particular. Furthermore, the HPLC-DAD method to determine morusin content is fast and reliable and is applicable not only to mulberry bushes but also to other plants.

An epithelial cell line was established from the leg skin of a patient with palatine carcinoma. On the basis of the studies of biological characteristics, such as rapid cell growth, neoplastic morphology, a large group B marker chromosome, the ability of the transplanted cells to produce tumor nodes in Wistar newborn rat, the cell possessing the structure of low differentiated squamous carcinoma and skin-like tissue, etc., we conclude that the PeaSE-1 cell line is an abnormal epithelium cell line.

We propose a feasible scheme of generating multipartite entanglement with the dipole induced transparency （D/T） effect in indirectly coupled dipole-microcavity systems. It is shown that the transmission spectrum is closely related with the interference of dipole-microcavity systems, and we can generate different classes of multi- partite entanglement, e.g., the Greenberger-Horne-Zeilinger state, the W state, and the Dicke state, of the di- pole emitters just by choosing an appropriate frequency of the incident photon. Benefiting from the DIT effect, the schemes may work in the bad or low-Q cavity regime only if the large Purcell factor of the dipole-microcavity system is fulfilled, and they are also insensitive to experimental noise, which may be feasible with present acces- sible technology.

Darcy's Law Expressed by Chemical Index

第六届新型太阳能电池材料科学与技术学术研讨会

CsAgBiBr has received great attention as an emerging double perovskite material. Some researches shown that the performance of the double perovskite material can be improved by doping other elements, but there is no report about solar cell with doping. We demonstrate Rb doping in CsAgBiBr can effectively increase the current and PCE of the device. Doping Rb can effectively modify the perovskite to reduce the density of defect states, while the absorption of long-wavelength is strengthened. We also found the optimizing ratio of Cs and Rb is 9:1. The device with(CsRb) AgBiBr achieves a maximum PCE of 1.52% and an ultra-high FF of 0.788 with the planar structure. And the average PCE is nearly 15% higher than the devices with CsAgBiBr. However, excessive Rb would lead to the formation of RbBiBr, and the perovskite film was deteriorated.

The Darcy's formula expressed by chemical indexes (ion activity a and saturation index β) is derived with the aid of the kinetics of multi-mineral dissolution. The implication of the formula and the relationship between the formula and the original Darcy's law expressed by hydraulic index (hydraulic gradient, Ⅰ) are discussed here. An analytic expression is established in this paper for the determination of the residence time of groundwater by chemical indexes, whose equivalence to isotopic age is studied. The formulas are derived from the calculation of permeability coefficient (K), conductivity coefficient (T) and actual velocity of groundwater (U). Finally, this paper introduces hydrogeological chemical kinetics constant (k j) and its determination method, differential and integral equations for chemical kinetics of groundwater in three-dimensional space.

本文以《德国浪漫派的艺术批评概念》为核心文本,考察了瓦尔特·本雅明的浪漫派研究。在这部早期的作品中,本雅明讨论了耶拿浪漫派的“批评”概念,并在此基础上指出,这一思潮的精神气质不是迷醉而狂热的,而是冷静而清醒的:它不沉迷于主观幻想,而是通过严肃的沉思追求客观真理;它并非偏狭的特殊性,而是关照着人类精神整体的发展脉络。这一讨论为本雅明回应现代性危机奠定了基础,它跨越了艺术理论的范畴,呼应了德国在世纪之交的现实处境,分享着德国社会理论的问题视野。讨论“批评”概念及其冷静清醒的气质有助于我们理解现代社会的危机以及本雅明早期作品对社会理论所做的贡献。
