1.Tests indicate that EMASOL 520B should be used at 15-45%by weight in paraffin base oil. And an excellent rust protection and hard watertolerance can be achieved.
2.The results show that when CR was 100 g, SBS was 20 g, MMA was 60 g ~70 g, BPO was 1.2 g, time of reaction was 4.5 h, reaction temparature was 85 ℃~88 ℃, the adhesive had more stripping strength, its watertolerance was satisfactory for use and its adhesion on SBS was improved.
4.It is very important to select tree species, which has lower water consumption and drought tolerance such as Pinus tabulaeformis and Platycladus orientalis, and set reasonable stand density in recovery and reconstruction of forest vegetation in CFF project on the Loess Plateau.
6.Method:Ammonia water induced cough model,capillary tube method,anoxia tolerance test were used to observe the cough relieving,sputum removing,anoxia tolerance effects of Ginkgo Dew.
9.The drought tolerance of sorghum is stronger than that of maize, its leaf relative water content and water potential are higher under drought condition.
