Based on the deterioration mechanism of corrosive medium, a lot of polymer such as ternary-polymer, adding-felt addition, hydrophobe and polypropylene fiber were added to enhance the performance of anti-corrosion, anti-penetration, conglutination and anti-cracking of original cementious material. The microstrure of cementious material was changed from the simplex hydration product of cement to the superposition structure of the hydrolysate of polymer and the hydration product of cement. A lot of the corrosive ions were prevented from the interior of concrete by this stable structure. The results of tryout indicated that the mending material has the good effect at the corrosion form of corrosive medium.

The methods of theory analyses and digital simulation have been used in this thesis and several schemes of strapdown guidance law based on analyzing the performance of several classical guidance laws have also been present according to the characteristics of strapdown Anti-Radiation homing seeker. The stapdown guidance systems were built for a certain Anti-Radiation missile, adopting acceleration autopilot and the attitude autopilot, and the paper has focus on analyzing the performance of low frequency strapdown Anti-Radiation homing seeker. The Approaches of lead correction and dead-zone relay control were given to improve the guidance precision, and also the increasable observability law was attempt and validate.

Several anti-tumor cell lines and carbonic anhydrase Ⅱ model were established. More than 10000 compounds and extracts from plants were screened using these models and about 10 compounds showed strong inhibitory activities. Two species of plants Inula helianthus-aquatica and Saussurea deltoidea were chosen to investigate chemical and bioactivity constituents based on the results of screening of extracts and fractions. 58 compounds were isolated and identified from these two plants, 6 compounds were found to be new and 14 compounds showed anti-tumor activities. We also studied the anti-tumor mechanism of the compound bigelovin isolated from Inula helianthus-aquatica. Bigelovin was found with apoptotic activity against cell line U266 by lowering the amount of important transcription factor E2F-1 which inhibits the cell cycle at G0/G1 stage. Docking study on 7 natural new phenolic inhibitors of CA Ⅱ and 3D-QSAR study on 61 sulfonamide inhibitors of CA Ⅱwere also investigated. The calculated results were in good correlation with experimental results.

MTT assay indicated that anti-proliferative activities in HeLa, SHIN3, HOAC-21 and HAC-2 cell lines were closely related to structure, 1,10-seco of eudesmane sesquiterpene lactone resulted in reduced anti-proliferative activity. The anti-tumor activity of isoalantolactone was probably achieved by inducing HeLa cell apoptosis.
