Then the listed companies having the corrections of accounting errors in the period from 1999 to 2004 were collected as research sample. Then the incidence which spurred the listed companies adjust errors in time was testified by methods of mean value test and multivariate linear regression. The major empirical results are summarized below: the inspection of The China Securities Regulatory Commission, other supervision outside and income quality correlated positively with it. The effect on profits correlated negatively with it. The hypothesis of the CPA firm change and assets-liabilities ratio didn't correlate with it.

然后选取了1999-2004年披露了会计差错更正的深沪上市公司作为研究样本，运用均值检验和Logistic回归方法考察了上市公司立即更正会计差错的动因，实证研究结果表明：证监会的检查、其他外部监管、收益质量与会计差错的立即更正正相关，损益影响程度与会计差错立即更正负相关，而事务所的变更假设和资产负债率假设未能通过显著性检验。

Letter Assigner process running, you can select from the main program interface corresponding disk drive, and then select from the bottom toolbar of a new drive letter, followed by the implementation of the menu bar of the "document"/"Save" command, and then re-start the computer system you can be so confusing letter "bring order out of chaos," the.

运行Letter Assigner程序后，你可以在主程序界面中选中从盘所对应的盘符，然后再从工具栏下方选中一个新的盘符，接着依次执行菜单栏中的"文件"/"保存"命令，再重新将计算机系统启动一下，就能使混乱盘符"拨乱反正"了。

This paper summarizes the background and advantage of data mining, as well as the significance of data mining in the scientific research management of colleges and universities firstly, and then discusses the theory of data mining, association rules and the ideas of main algorithm, analyzes the classic Apriori algorithm and its existing problems as well as the basic solutions.

Their reverence for trees can be seen by the way they live. For every tree they cut down, they must plant one seed; when children are born, the parents will then plant a tree which, when one dies, is then made into their coffin, and with each burial, another seed is planted, representing that their life will begin anew. Because of this, Basha village is full of trees and no graves are to be seen.

人们对树的敬畏贯彻一生，他们每砍伐一棵树，必再种一棵；孩子生下来以后，父母也会种下一棵树，直到他死亡将此树制成棺木，并在下葬处再植一棵，代表他的生命又重新开始，因而在岜沙村只见满目树木却无坟冢。

If the name was determined by the nature of the object to which it referred, then language was physis, that is, it could be said to reflect the true nature of things, but if it were nomos, then the name could not serve as a source of real knowledge.

如果名称是由其所指对象的本质而决定，那麼语言就是物理，也就是说，语言可以反映事物的真实本质，但如果语言是法则，那麼事物的名称就不能作为真正的知识来源。
