浅谈声发射振动复合传感器浅谈声发射振动复合传感器随着全球经济和自动化工业的迅速发展，人们对设备故障特别是轴承类的故障诊断也日益重视起来了。为满足客户对旋转仪器轴承异常的精准诊断，单一的依靠振动信号或声信号分析，是很难兼顾轴承的多种异常情况的。为此，市面上开始着手研发出了可同时分析机械设备的振动信号和声信号的复合型传感器。初期的复合型传感器主要有 2 种类型，下面以 A、B 来举例说明。 A 型是在被测物表面不同的 2 个位置分别放置声发射(AE)传感器和加速度(ACC)传感器，它虽能一定程度... 阅读详情

dwFileAttributes :
Specifies the file attributes of the file found. This member can be one or more of the following values. Attribute Meaning
FILE_ATTRIBUTE_ARCHIVE -------The file or directory is an archive file or directory. Applications use this attribute to mark files for backup or removal.
FILE_ATTRIBUTE_COMPRESSED ----The file or directory is compressed. For a file, this means that all of the data in the file is compressed. For a directory, this means that compression is the default for newly created files and subdirectories.
FILE_ATTRIBUTE_DIRECTORY -----The handle identifies a directory.
FILE_ATTRIBUTE_ENCRYPTED -----The file or directory is encrypted. For a file, this means that all data in the file is encrypted. For a directory, this means that encryption is the default for newly created files and subdirectories.
FILE_ATTRIBUTE_HIDDEN --------The file or directory is hidden. It is not included in an ordinary directory listing.
FILE_ATTRIBUTE_NORMAL --------The file or directory has no other attributes set. This attribute is valid only if used alone.
FILE_ATTRIBUTE_OFFLINE -------The file data is not immediately available. This attribute indicates that the file data has been physically moved to offline storage. This attribute is used by Remote Storage, the hierarchical storage management software in Windows 2000. Applications should not arbitrarily change this attribute.
FILE_ATTRIBUTE_READONLY ------The file or directory is read-only. Applications can read the file but cannot write to it or delete it. In the case of a directory, applications cannot delete it.
FILE_ATTRIBUTE_REPARSE_POINT -The file has an associated reparse point.
FILE_ATTRIBUTE_SPARSE_FILE ---The file is a sparse file.
FILE_ATTRIBUTE_SYSTEM --------The file or directory is part of the operating system or is used exclusively by the operating system.
FILE_ATTRIBUTE_TEMPORARY -----The file is being used for temporary storage. File systems attempt to keep all of the data in memory for quicker access, rather than flushing it back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed.
