摘要：
CAD graphic preview and interaction is a key problem in the mould collaborative design syetem. It can realize with Java Applet program, but it is necessary to development Java Applet program,that will restrict many terminal users of the mould collaborative design syetem.In order to realize the problem that terminal users can preview CAD graphic, correct and transfer the CAD graphic to other terminal users easily and quickly, this paper put forward a way that terminal users can use previewing the original data file of AutoCAD graphic, correcting and transfering the CAD graphic to other terminal users,the way is using the Voloview control program which developed by Autodesk company, and put forward the concrete methods and steps to achieve.Test shows that, the way can meet the terminal users requirements and implementation in mold collaborative design syetem.

摘要：
Poria cocos (Schw.) Wolf is a well-known traditional Chinese herbal medicine that has been used as diuretic, sedative and tonic drug. However, the natural P. cocos forms sclerotia on the roots of cedar or pine, its productivity is limited. Therefore, it is imperative to find a cultivated P. cocos substitute for the natural one. A new cultivated P. cocos strain numbered 28 was selected in the State Key Laboratory of Sub-health Intervention Technology. In this study, antagonistic effect was done to test the relationship between P. cocos 28 and a natural strain (numbered 578). The molecular marker SRAP (Sequences-related Amplified Polymorphism) amplification and cloning, sequencing of 2 ORFs (Open Reading Frame) fragments were applied to analyze their genetic diversity. The phenol-sulfuric acid procedure, spectrophotometry and amino acid standard analysis methods were used to determine the concentration of active ingredients - polysaccharide, triterpene and amino acid, respectively. There was an obscurely shaped line in the antagonistic effect and none of 132 SRAP primer combinations turned out to be polymorphic. Sequencing of 2 ORFs fragments showed that there were only 59 mutant sites with 25 conversion, 22 transversion and 12 insertion or deletion. No significant difference was detected in the contents of active ingredients between P. cocos 28 and 578. Therefore, the cultivated P. cocos 28 could be the alternative strain of natural P. cocos 578. This study indicated that antagonistic effect and SRAP marker could be effective methods to analyze the relationship of P. cocos and would be useful in selection of high-yield cultivation of P. cocos.

摘要：
Rice production in Asia is increasingly constrained by water limitation as a consequence of global water crisis.One of the technology options that can help farmers cope with water scarcity at the field level is alternate wetting and drying (AWD).Nitrogen (N) is also an important factor which often interacts with water and influences rice growth.
