此外，很重要得一点是，Purify只在运行测试的过程中对部分的程序进行错误的检验。
In addition, it's important to know that Purify only does error checking on parts of your program that run during testing.
一般情况下，DOM实现必须检验操作的正确性，并在应用程序传递错误参数或者执行非法操作时抛出异常。
Normally, a DOM implementation must verify the correctness of operations and throw an exception if an application passes the wrong parameters or performs an illegal operation.
数据库验证是捕获错误的最后机会，但是好的应用程序应该事先检验数据(数据库引擎的错误消息可不是易读的)。
Database validation is the last chance to catch errors, but a good application has already validated the data at that point (and error messages from the database engine are anything but readable).
状态检验(Static verification)可以查找多种通常的程序逻辑错误，如不恰当的使用一个在编译时而不是运行时的方法。
Static verification offers the promise of finding many common errors in program logic such as possibly improper use of a method at compile time as opposed to at runtime.
我测试过这个模拟器和惠普jornada应用程序，但我没有时间来检验每一项内容，因此它仍然可能有错误的地方恶劣的崩溃。
I've tested this app on the emulator and an HP Jornada, but I didn't have time to test every part of it, so it still could have a nasty crashing bug somewhere.
