One large , randomized study in 2005 , for example , compared various treatments and found that after seven days , about 70 percent of subjects who combined heat therapy with light exercise returned to “ pre - injury function , ” compared with 20 percent who used heat or exercise alone 2005年的一个大型的随机实验,比较了很多不同的缓解背痛的疗法,在7天后, 70 %的接受热疗法,同时又进行轻微运动的样本,与20 %只接受热疗法的人相比,他们又回到了背痛前的行动状态。
In this paper , the authors give an initial probe into probability theory from different angles , including window method ( specialization and characterization of probability model ) , clue method ( building model clues to the theme according to the subjects ) , index method ( clue to key words in bilingual teaching ) and experiment method ( random experiment between people and machines ) , which are of significance for reference 文章通过教学实践归纳了开窗法(概率模型的现代化与特色化) 、联珠法(面向对象有针对地建立贯穿主题的模型线索) 、语素法(双语教学中关键字的提示) 、实验法(开展人机交互的随机实验)等方法,具有一定借鉴意义。
In the case of the maximal observed area model , the complexity of the problem was studied first , and come to the conclusion that this solve problem of this model is a np problem . so , genetic algorithm ( ga ) and greedy algorithm is applied to solve this problem 对空间覆盖率优先问题,分别应用遗传算法及贪婪算法对其实现了近似求解,并通过对这两种不同求解算法的特点及复杂性进行分析,明确了这两种算法的适用条件;随机实验也进一步说明了两种算法的优缺点所在。
