The system mainly includes: a unit for monitoring the heartbeat of the processes in the system, and the process regularly reports heartbeat messages to the unit for monitoring the heartbeat of the processes in the system; The condition of the message identifies the abnormal unit of process. By using the method and system of the present invention, the abnormal exit of the process can be monitored in real time, and various forms of sub-process exit conditions and corresponding abnormal exit reasons can be monitored.

The invention relates to a deep recovery method for the database content, which is realized by the following steps of: (1) pre-processing stage; and (2) matching stage: after the pro-processing is finished, notifying a protocol analysis module, reading a built database operation stream file by a process, reading the file line by line, invoking a kmt algorithm, and analyzing the real database operation in the line. According to the deep recovery method, a database operation process can be truly recovered, a database access behavior can be effectively monitored, the safe state of a database system is accurately mastered, events which violate a database security policy are found in time and are alarmed and recorded in real time, security incident positioning analysis and afterward tracing and evidence taking are convenient to carry out so as to guarantee the security of the database, and whether violated keywords exist is analyzed on the existing basis after the database content is completely recovered.

The invention provides an interpolation method for CT image layer data. Assuming that a CT image totally has N layers of CT pictures, interpolation operation is conducted on the N layers of CT pictures. The interpolation method for the CT image layer data comprises the following steps that an average picture between every two adjacent layers of pictures of the N layers of CT pictures is calculated, and N-1 average pictures are obtained; Gaussian smoothing processing is conducted on the N-1 average pictures, and high-frequency noise is filtered; interpolation rebuilding coefficients are established, and an interpolation rebuilding image is obtained. According to the interpolation method for the CT image layer data, and the artifact phenomenon caused by interpolation failure due to the fact that interlayer data are not aligned can be avoided. The interpolation method for the CT image layer data enables transition between every two layers of the CT images to be smoother, analyzing and positioning can be conducted more conveniently, and diagnosing accuracy can be effectively improved.
