The demonstrate in can asking to develop a process of course (safeguard a map by development staff for example, a of the ID interfacial element and tiring-room or correspondence of a group of operations rises), what I need to solve now is how to let the system discovers automatically and maintain these relationships Read above oneself problem, discovery had a direct result to be told to the system,"Authority " the ID that is an interface element and the URL that a group of tiring-room serve (take no account of data to visit attributive temporarily), attributive ={id, comId, urls, desc} such, how can problem translate into realize the definition of attributive, let him user input ComId, Urls?

当然可以要求开发过程中指明（例如由开发人员维护一个映射，把界面元素的ID和后台的一个或者一组操作对应起来），我现在需要解决的是如何让系统自动发现和维护这些关系读了上面自己的问题，发现有了个直观的答案对于系统来讲，&权&就是一个界面元素的ID和一组后台服务的URL（暂时不考虑数据访问权限），权限={id，comId，urls，desc}这样，问题转化为如何能够实现权限的定义，让用户自己输入comId、urls吗？

A-Methylnaphthalene contains a methyl group, which is a strong donor group, so the reaction of a-methylnaphthalene with C14 AOS acid had a higher conversion of aromatic than did the reaction of benzene with C14 AOS acid. After alkylaryl sulfonic acid is formed, it will continue to react with another AOS acid to rapidly produce dialkylaryl disulfonic acids owing to the electron- donating effect of the long alkyl chain in the alkylaryl sulfonic acid molecule.

a-Methylnaphthalene包含一个甲基集团，这是一个强大的捐赠团体，所以 a-methylnaphthalene反应出了与C14酸更高的转换的反应比苯与C14活性氧酸。alkylaryl磺酸为后形成，它将继续与另一出酸 dialkylaryl disulfonic迅速产生的电子-酸捐赠的长期效果在alkylaryl烃链磺酸分子。
