This paper narrates the theory method to determine measuring points in the ubiety of center of road of first easement curve segment,circle curve segment and second easement curve segment,gives the source program of PC-E500 computer and explains data format in it.

In view of the problems resulting from that presently the measuring points of large units performance.

The experimental methods of modal analysis on the 2YZS4375 high-efficient vibrating sieve with double masses are expounded, including the trial lest of the measuring points, the formal test, the identification of modal parameters, the vibrating morphology analysis of the screen, data analysis and conclusion obtained.

In this paper,the design of the testing points and testing methods for the system is mainly dealt with.

The optimal arrangements of measured points for supervisory control technology and back analysis of tunnels engineering;

In the construction control of the partial cable - stayed bridge, embedded measured points were commonly used to monitor the construction procedure for aquiring more accurate data, which are necessary for infor-rnationalized construction.

When LDA is used,the distortion of control volume and the deviation of measured points are analysed by using the light tracked method when the beams pass through a circular medium such as an agitator.

When comprehensive loads in regional power grid are modeled based on measured data, the fuzzy clustering theory is applied to classify substations, in which the representative substations are chosen as the measured points to measure load features.
