Most of the existing earthquake disaster assessment systems take districts, counties or townships as evaluation units. Due to the lack of data accuracy, there is a big gap between the evaluation results and the actual losses. With the development of technology, the acquisition and update of residential data is more convenient and rapid. Compared with the evaluation system based on districts, counties or townships, the results of the evaluation system based on residential areas are more detailed and accurate. In this paper, the existing calculation model as the skeleton, ArcEngine as the GIS development platform, using C / S structure to design the seismic disaster assessment system under different intensity based on residential area. The system takes the residential area as the evaluation unit. According to the selected assessment area, the system evaluates the damage of buildings and casualties of earthquake disasters according to the five grades of VI, VII, VIII, IX and X. The results can provide technical support for governments at all levels and relevant departments to carry out regional earthquake risk assessment and earthquake disaster pre assessment.

An online energy analysis system for paper machine dryer section is developed. The data and information share is realized in different types of database. Supervisory and analysis software plays an important role in the system, such as iFIX of GE and eTMS. the techniques of gathering and analyzing the real time data from the paper machine dryer section and communication between different software are also introduced. The running result of the test shows that the system has a good effect for the paper machine optimizing operation, energy-saving, and consumption-reducing.

Barley chloroplast mutant ‘Yellow-green 1832C’ was used to study the pigment-protein complexes and chloroplast ultrastructure in comparison with the original variety ‘Hedist’. By means of sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) chloroplast thylakoid membrane of control was separated into six pigment bands, but in mutant only three bands were obtained. Analysis of absorption spectra indicated that three bands of CPII, i.e. light harvesting chlorophyll a / b -protein complexes were completely absent in mutant. It meant that synthesis of chlorophyll b in mutant might be impaired. Electron microscopy also showed some differences in chloroplast fine structure between mutant and control.

Comparative studies on the chloroplast thylakoid membrane polypeptides between cytoplasmic male sterile lines and their respective maintainers from sugar beets, maize and sorghum were performed by applying two dimensional electrophoretic separation techniques. Differences in the size, number and distribution of resolved peptide spots near 33 kd were observed between CMS and their maintainers. This indicates that variation of composition of the thylakoid membrane proteins is correlated with the pollen sterility.

One dimensional SDS-PAGE and two dimensional electrophoresis of the thylakoid membrane proteins of a barley mutant and its original variety were carried out. It was found that (1) approximately 20 bands could be identified. The mutant lacked one band at 23 kd, and two bands at 17.5 nd 18.3 kd were fainter when compared with the original variety which served as the standard. (2) In two dimensional patterns the 23 kd band was resolved into two faint bands which were composed of three peptide spots having a pH of 6.35, 6.46 and 6.50, respectively. The band in the 17–18 kd region was resolved into five heavy peptide spots with varying pH values of 6.35–6.62.

This paper deals with the relationship of chloroplast DNA (ctDNA) and cytoplasmic malesterility (CMS) of maize, wheat and rape. Intramolecular heterogeneity and fragment patterns of DNA digested with restriction endonucleases were compared and analyzed. For this purpose methods of agarose gel electrophoresis and two dimensional gel electrophoresis with denaturating solvent concentration gradients were applied. 1) Heat denaturation of ctDNA from a male sterile line in maize yielded a profile with three melting regions. This base sequence heterogeneity was not observed for the ctDNA of its maintainer. 2) Maize ctDNA was digested with EcoR1 and BamH1 restriction endonucleases, wheat and rape ctDNA with EcoR1 only. No significant differences were observed in the comparison of the fragment patterns from the sterile lines and their maintainers with the exception of the sterile line in rape which lacked one fragment present in its maintainer. 3) Two dimensional electrophoresis using a gradient of denaturing agents revealed several differences in number and relative positions of the separated restriction endonuclease fragments between the sterile lines and their respective maintainers in all three tested crops. This raises the possibility that changes in ctDNA may be involved in CMS.
