TiO 2 anatase thin films on quartz substrates were prepared with sol gel method. The dry gel films, made by spin coating 10 times, were calcined at various temperatures. From X ray diffraction analyses, it is found that the anatase to rutile phase transformation temperature of the films is higher than 850 ℃, the films are preferentially oriented on (0 0 1) plane, i.e. c axis oriented. The thickness, refractive indexes, absorption coefficients and extinction coefficients of the films were determined from UV Vis transmission spectra of the films using a UV Vis spectrophotometer. The thickness of the films is about 570 nm. The refractive indexes, absorption coefficients and the extinction coefficients of the present films are larger than the values of anatase films prepared by sputtering. This indicates that the films made with sol gel method are very dense.

In this work, a novel duplex Ni-P/Ni-Mo-P coating upon the aluminum（Al） substrate was synthesized via an electroless plating, i.e., the binary Ni-P coating as a transition layer and the ternary Ni-Mo-P coating on the top. It was found that the duplex coating was of a high hardness,large elastic modulus,low porosity and excellent corrosion resistance. In addition, experimental results revealed that for a total 20 μm coating thickness, the duplex coating with a 7 μm of the Ni-Mo-P coating exhibited the best corrosion resistance in 0.5 mol/L sulfuric acid solution, which was attributed to its compact structure and low porosity. This duplex Ni-P/Ni-Mo-P coating with a thin ternary Ni-Mo-P layer is expected to solve the problem of low deposition rate of ternary alloy coating and thereby may expand applications of Al and its alloys in the fields of machine manufacture and corrosion environment.

Agricultural Sciences in china 2010年第9期9卷 1317-1325页

作者： ZHENG Jia-guo chi zhong-zhi JIANG Xin-lu TANG Yong-lu ZHANG Hong Tillage and Cultivation Research Center Sichuan Academy of Agricultural Sciences Chengdu 610066 P.R.China

The rice and wheat cropping pattern is one of the main cropping systems in the world. A large number of research results showed that successive cropping of rice and wheat resulted in a series of problems such as hindering nutrition absorption, gradual degeneration of soil fertility, decline of soil organic matter, and increased incidence of diseases and pests. In china, especially in the Chengdu plain where rice-wheat cropping system is practiced, productivity and soil fertility was enhanced and sustained. This paper reviews the relevant data and experiences on rice-wheat cropping in the Chengdu Plain from 1977 to 2006. The principal sustainable strategies used for rice-wheat cropping systems in Chengdu Plain included： 1） creating a favorable environment and viable rotations; 2） balanced fertilization for maintenance of sustainable soil productivity; 3） improvement of crop management for higher efficiency; and 4） use the newest cultivars and cultivation techniques to upgrade the production level. Future research is also discussed in the paper as： 1） the constant topic： a highly productive and efficient rice-wheat cropping system for sustainable growth; 2） the future trend： simplified cultivation techniques for the rice-wheat cropping system; 3） the foundation： basic research for continuous innovation needed for intensive cropping. It is concluded that in the rice-wheat cropping system, a scientific and reasonable tillage/cultivation method can not only avoid the degradation of soil productivity, but also maintain sustainable growth in the long run.

采用等温和非等温差示扫描量热(DSC)法研究了聚丙烯规整性和分子量对其结晶性能的影响。结果表明,采用等温结晶分析,聚丙烯的规整性与其熔点成线性关系。但对于分子量很低或规整性很高的聚丙烯,其熔点和规整性不符合以上线性关系。采用非等温结晶分析,聚丙烯规整性的对数与其熔融焓的对数成线性关系。对乙烯共聚研究结果说明,对高规整性聚丙烯,极少量乙烯共聚也会影响其规整性。

西方协商民主理论思潮影响中国是不争的事实。将引自西方的协商民主与中国内生的独特的协商民主两个概念相混同,造成了误读、误导,以致出现"西方的理论中国的实践"的偏颇。廓清西方协商民主复杂的理论流派,从其概念框架和框架概念两个层次分析,可对其达到一种秩序化的认知;在理论与经验的关系上审视其现实化的可能性,可为理解西方协商民主提供一种批判与鉴别的视野。

20世纪90年代以来,西方政治、公共事务变革出现了两个流行概念:新公共管理与治理。这两种思潮都对中国产生了很大的影响。在国家治理成为热点之时,往往从治理与管理的词义差别上确定其论证逻辑,这是有局限的。引入斯金纳的"历史语境"方法,展现公共行政、新公共管理、治理发生的时间及其交织形态,从公共哲学的途径显现西方治理理论的意识形态基础,以此折射中西差别。

讨论协商民主的价值固然重要,但协商与民主的结合才是协商民主的。如果忽视协商与民主的关系问题,那么有可能事与愿违。自西方协商民主概念产生以来,协商与民主的矛盾问题就凸显出来,由此西方学者形成了协商民主概念是否成立、如何解决协商与民主统一的问题议程。中国学者已经形成了关于中国的协商民主概念是舶来还是内生的讨论,虽然在一定程度上关注协商技术的问题,但更多停留在西方学者观念的应用中。中国民主政治实践所创造的协商民主贯穿着如何实现协商与民主相统一的逻辑,揭示其内在机理,有助于深化对中国协商民主之独特性的理解。
