The fluctuation of available wireless link bandwidth motivates the study of adaptive multimedia services in wireless/mobile networks This paper focusses on a bandwidth adaptation scheme, which takes the maximum revenue as the objective The optimal bandwidth adaptation algorithm which seeks to achieve maximum revenue is an NP hard problem, because it has to investigate every adaptation case A bandwidth adaptation scheme based on genetic algorithm is proposed, which achieves near optimal total revenue with much less complexity compared to an optimal bandwidth adaptation algorithm Simulation is carried out to compare the algorithm with an optimal bandwidth adaptation algorithm, the results reveal that the genetic algorithm approximates the optimal solution very well

Objective: This experimental study is based on earlier animal and clinical experiment, drawn thinkings of combinations with two methods and pursued a synthesis method of high-efficiency, cheap and convenient calcium and exercise treatment. We adopt taking natural-clam's casing powder and preconcereted-intensity excises to intervene shape of osteoporosis in gelded rats, than we compare the indexes such as the biomechanics indexes of the right femur and the third lumbar vertebrae, the weight and uterus quotiety of rats before the experiment to these indexes after the experiment. We hope to find better and suitable way to prevent and treat the postmenopausal osteoporosis and offer reference for clinic.

目的 本实验的主要目的是在前期动物实验的基础上，引入两种方式联合干预的思维，立足于探求既高效又经济、方便的补钙剂加上与运动疗法相联合的方式，对切除雌性大鼠卵巢而复制成的骨质疏松症模型进行服用天然贝类蛤蜊壳粉，同时施以预定强度的运动刺激的方法，再通过试验前后大鼠体重、子宫指数的变化及大鼠股骨和椎体生物力学指标的对比变化进行分析，以期探索出防治绝经后骨质疏松症的更好的、更适宜于大众的手段；并为天然钙剂和运动联合作用防治PMOP提供参考。
