Hi eryar,

我用的是V1.2的，cmd窗口有这样的提示，看不懂了，需要您的帮助：

您好！我用的是12.1sp2，导出的时候，程序无响应，然后退出了，尝试了很多次,是什么原因呢？

看了楼上给的原文，感觉判断lvalue和rvalue的方法就是看if it is refer to an object。因为原文中有这样一句An object is a manipulatable region of storage; an lvalue is an expression referring to an object....

google 双检锁

任何有ran()+ran()的方法都是不行的，
就像扔2枚骰子，和为2和6的概率是不相同的

在vc下测试，右移32位，就是本身值。记得书上说，有些编译器，在移位时，先对其取32的模。

谢谢楼主的点拨，深受启发，解决了心中的困惑

感激不尽~~~~太感谢了！！！！

呵呵你们的滴电脑好卡啊，我只用了1秒钟哦。

你好 我在装网格环境时 上面都成功 但执行
http://localhost:8080/wsrf/services时出现错误

这本来就是一种未定义情况，如同snprintf中将自己作为一个参数一样…

删了Ogre.cfg 也报错...

1.5题
normal-order evaluation是先替换参数，到最后才会计算操作数。
而applicative-order evaluation是开始就计算操作符和操作数，而后再替换参数。
所以题解应该是反的。

16bit Z buffer的分辨精度是 2^16,类似的24bit 是 2^24.和芯片硬件设计相关。无法精确表达3个double值获得的深度值。

深度值是世界坐标XYZ在屏幕坐标UVW的W方向的投影。

OpenGL 将其转换为0-1之间的浮点值，我认为是为了使OpenGL调用与硬件配置无关，类似的设计在颜色设置等方面也可以看到。

这有什么，拼命锻炼假装没听到呗

请问怎么刷新IE后文档不能显示啊？还有我每次只能是第一次下载安装控件时可以正常使用，以后打开网页都不能显示文档内容。
