advantage in this respect has been attributed to three groups of factors: (i

It is anyway unlikely that Churchill would subscribe to this

Liberal Party (which was not liberal in the modern sense), and later
went back to the Conservatives.

论神
━━伟大的设计家
一、序言
多年前先知但以理曾说：“惟独认识神的子民，必刚强行事”（11:32），这句话在他与
其三友的生平中不鲜凡例，诚如英国名神学家柏克博士（J. I. Packer）在其精着“认
识神”（Knowing God）一书内论但以理时称：1)认识神者必有极多精力为神作工；2)认
识神者必常想念神；3)认识神者必勇敢为神而活；4)认识神者必以神为人生之满足〔注
1〕，是以认识神为所有属神者不可忽略的功课，如何西阿先知呼叫：“我们务要认识神
，竭力追求认识他。”（6:3）
二、有关神存在的理论
历世历代不少人对神的存在采取不同的臆测，既然出发点来自人方面，这亦指出人性先
天固有的宗教感，虽然所循找的路线各自不同，但人性内的“向神意识”是一件不能否
认的事实。下面略述各人对论神的“认识”：
1.无神论（Atheism）
无神论虽是否认神存在的一种定论，但它却非盲目地加以否认，此论先是一种对传统证
实神存在各论据所表示的不满，进而干脆否决了神的存在。无神论亦分四派: 1)传统派

1 ROW/TUPLE in left entity is associated with many ROWS/TUPLES in right entity,
not 1 COLUMN/ATTIBUTE to many COLUMNS/ATTRIBUTES.
Your case is two COLUMNS/ATTRIBUTES in a table referring to another table.
This is not 2-to-many relationship in ER model. This is just 2 foreign key

在初级的DBA，也不会这么命名吧。我只是简单说col1，并不是column1的header就是

这样说吧，table1的attributes在数据库中被分成好几类，比如，身高，体重属于body
index，心跳，血压属于health index（table2）。
要生成的table3，就是id attribute 在加上 attribute的类别。
其实这就是个sql问题，跟这些都无关。

我大概猜测是这样
people_otherStateBenefitQuestion是request里面一个attribute
从request中get这个attribute
那么在发送这个request的时候，肯定有一个地方把这个request给set进去
如果是mvc结构的话，到view一般是最后一步了
一般经过ejb处理之后才到view，所以从ejb中找这个collection
然后从你给出的代码看，它是从session中取得这个collection对象
然后放到pageCollection里面去
我的猜测就是这个pageCollection对应着request
而put到这个pageCollection里面去的所有对象，最后都会变成request的attribute

虽然有很多这样那样的类库，但是一旦涉及到复杂的应用就挂了
两个例子
一个是我上次举的，html5所采用的attribute来替换javascript

html5的input新attribute 就有type=date的选项
各个浏览器分别impl，你要用直接敲一个attribute就好了
自己去写岂不是吃饱了撑着？
另外一个，内存管理的例子

它们是可识别的属性。
实际上，对于后一句，我想表示的是，这些可识别的属性之间是互不相同的，而
identifiable又有“可同一的”的意思，也就是说，They are identifiable
attributes其实说的是“它们是同一个属性。”我的理解是正确的吗？
