一个_bstr_t字符串能够传给一个接收参数类型为BSTR的函数，只是因为下列3个条件同时满足。首先，_bstr_t有一个向wchar_t*转换的转换函数；其次，对编译器而言，因为BSTR的定义，wchar_t*和BSTR有同样的含义；第三，_bstr_t内部含有的wchar_t*指向一片按BSTR的形式存储数据的内存。

这是一个值得怀疑的设计，因为即使它们是非常量字符串指针，你也一定不能使用这些指针去修改它们指向的缓冲区的内容，因为那将破坏内部的BSTR结构。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
