Audit takes a unique status and has obvious function in financial surveillance system.The Audit is used to superintend the factuality,validity and virtue of fiscal and financial income and expenses.In the renewed China Audit law the functions and status of official audit have been intensified,and the qualification and status of Audit department as executing office is confirmed.This paper analyzed the official construction project audit's function and legal status.     

Grid Workflow Management System Research and the Realization Based on the OGSA

Grid applications have evolved from science research to business and manufacture field, in these fields, tasks always process in workflow mode. In order to found a workflow management system in grid , the authors adopt a hybrid grid workflow engine after analyzing the characteristics of grid environment and give a referenced model of workflow management system in grid that is based on the engine. Through the examination, the authors prove the original intention is feasible.     

Detecting Technology of Cabel Surface Defect Based on DSP and Image Recognition

The damage of bridge cable directly hazards the normal use of bridge and the safety of people. The paper discussed the signal acquisition and detection system which takes embedded DSP processor as core technology, combined with CCD, video decode chip, SDRAM, FLASH ROM, and established the fast measuring algorithm of the surface corrosion and damage, which includes deteminating the processing region, improving medium filter, sobel edge detection and dynamic threshold segment, close operation of morphology, computing defect area and saving. The experimental resuits show that this method implemented the real-time, non-contact and intelligence detecting of cable surface defect and gives the specifications of the system.
