大哥,也给点劳力费吧.那么长啊!
Manage the household materials degrade performance often determines the success or failure of the treatment works organizations. The impact Juyi C esters plant material degradation rate is primarily lactic acid and gather together Yichunsuan ratio, molecular weight materials, pore rates and aperture size, the pH value of media degradation, and have been in the literature have detailed study. However, after carrying materials into the complex dynamics of stress in different parts of the human body, different organizations are markedly different. For cradles degradation process in the body or in vitro studies, implanted material which stress environmental degradation performance for the organization works supporting material impact study is also unusual. Therefore, the study stresses the role of PLGA from a new perspective on the material degradation of plant material will degrade performance organization works with the new awareness. The study plus stress on the plant material degradation dynamics effects. First experimental device designed stretch and compression testing devices can exert stretch of the material or compression stress stress the role and then choose to have molecular weight 150,000, pore rates, aperture were 90%, 400 16ug m and 50%, 100 two 16ug m stretch material degradation experiments, the selection of the molecular weight is 40,000, pore rate 90% 400 m aperture 16ug materials compression degradation experiments. Solution in PBS (pH 7.4 37 degrees) degradation week, in vitro simulation of different materials relating to the role of environmental stress. Explore different degradation times the molecular weight and distribution of plant materials, absorbent volume, weightlessness, particularly mechanics, and other characteristics of changes and micro-structures and morphology observation. Week degradation experiments showed that, in addition stretch or compression stress the role of the quality of materials and molecular weight loss accelerated, absorbent materials volume and surface hole, aperture significant changes, the mechanics of materials properties in particular tensile yield strength, and compression strength and Ms. Yang modules of markedly lower. Experimental results indicate stress on the organization works supporting material degradation plays an important role in the design of future materials, the need to focus on supporting consider stress factors.
