＜正＞The new species Melanospora subterranea is described from China,based on morphological and phylogenetic *** is the first record of Melanospora species parasitizing Chinese black and white truffles（Tuber indicum and T huidongense）,and its host range indicates that the new species may be a disease threat to commercially exploited European truffles including Tuber melanosporum and Tuber *** polyphyly within the Ceratostomataceae can be explained at least in part by inadvertent sequencing of the host fungus rather than the parasite.

fluidized Carbon Bed Cooling(fCBC)is an innovative investment casting process for directional solidification of superalloy *** takes advantage of a fluidized bed with a base of small glassy carbon beads for cooling and other low-density particles that form an insulating layer by floating to the bed *** so-called“Dynamic Baffle”protects the fluidized bed from the direct heat input from the high-temperature heating zone and provides the basis for an improved bed *** prerequisites for a stable casting process are stable fluidization conditions where neither collapse of the bed nor particle blow out at excessive bubble formation *** work aimed to investigate the fluidization behavior of spherical carbon bed material in argon and air at temperatures between 20 to 350℃.Systematic studies at reduced pressures using the fCBC prototype device were performed to understand the stable fluidization conditions at all stages of the investment casting *** particle shape factor and size distribution characterization and the measurement of the powder’s minimum fluidization velocity and bed voidage show that this material can be fully utilized as a cooling and buoyancy medium during the fCBC process.

The effect on spore germination of the entomopathogenic fungus Lecanicillium muscarium following direct exposure for 24 h to the insecticides Majestik, Spray Oil, Agri- 50E, Savona and Oberon for the control of both egg and second instar stages of the sweetpotato whitefly, Bemisia tabaci, was determined. Exposure to both Agri-50E and Oberon was followed by acceptable spore germination. Infectivity rates ofL. muscarium on poinsettia foliage in the presence of dry residues of the insecticides were also investigated. No significant detrimental effects on the levels of control of B. tabaci were recorded compared with fungus applied to residue-free foliage. Sequential application of the chemicals Savona, Spray Oil and Majestik with the fungus all produced mortalities of second instar B. tabaci above 90%. Incorporation of these chemicals with L. muscarium into integrated control programs for B. tabaci is discussed.

In the last two decades of the 20th century, there has been an increasing interest in and emphasis on the study of the Hong Kong literature in both the academic and general public in Hong Kong. Recognizing the emergent need of the resources on Hong Kong literature, the University Library System of the Chinese University of Hong Kong set up the Hong Kong Literature Database （the “Database”）, which was the first Chinese literature database in the Internet in 2000. The paper will examine how the database is constructed using XML technology andometadata schema, The database also employs Unicode UTf-8 as the internal code. A mapping table for traditional and simplified Chinese characters was created based on Unihan and is used behind the scene so that a user can either input traditional or simplified Chinese characters and retrieval will give both traditional and simplified Chinese characters. Currently 65% of journals use OCR technology so that full-text searching is possible. The Chinese OCR technology will be examined in greater detail. Special features of the Database such as, page-by-page browse mode, position-highlight for full-page newspaper, linking Table-Of-Contents and book jackets from the Library catalogue, etc. are described. The paper will also bring out the problem of massive downloading and compare the state-of-the-art technology and their shortcomings. This paper shows how the Hong Kong Literature Database facilitates future collaboration and data exchange by using open standard, shareable structure and the latest technology.

基于1964—2003年内蒙古有关台站的逐日气温数据,对前20年(1964—1983年)和后20年(1984—2003年)的候平均气温中值进行了对比,并利用k-means方法进行了候平均气温变化趋势的聚类分析,旨在阐明内蒙古气温变化的时空特点和规律。研究结果表明:内蒙古全境年平均气温普遍上升,没有下降的现象。不同地区、不同季节气温变化格局不同,北部变暖比南部更为明显,冬季和夏末秋初变暖出现得更频繁。绝大部分地区大多数候平均气温都有所上升,而且候平均气温变化存在纬向地带性。大多数台站四季里都有一些显著升温的候,显著升温在冬季发生得更为频繁。同时,有少数几个候出现气温下降的现象,但未达到显著下降的程度。内蒙古绝大部分地区候最高、最低气温都有所升高,但二者的差值在缩小。候最低气温出现时间有所提前,候最高气温出现时间有提前也有推迟,但总体上不同地区候最高、最低气温出现时间更加同步。因此,候最高、最低气温的时空均一性有所增强。候最高气温出现时间与候最低气温出现时间的间隔有扩大迹象。总之,全球气候变暖降低了气温的季节和地区差异。
