Aiming at the measured behavior of the slab,it s stressed that some aspects should be considered as the monitoring points of the important monitoring items were arranged.

Based on monitoring works on tunnel of Hang-qian highway, the monitoring item selection and sensor placement optimization are discussed in this paper.

Furthermore, the basic monitoring items and methods of some marine eco-environmental monitoring factors, including ecological, biological and physical factors, are studied deeply and systematically.

In this article, by analyzing current situation of domestic monitoring design for dam safety, methods for determination of monitoring items and measuring points arrangement are proposed on the basis of specifications for dam safety monitoring, risk analysis, and comparison with other calculation data and results of model experiments.

Analysis on target surveillance of cardiac surgical site infection;

Target monitoring and preventing iatrogenic infection of disinfection work

Target monitoring had a much higher positive rate than routine monitoring (P<.

It establishes the target monitoring-forecast modles and control-hormonization rules on the construction progress planning,construction cost and resource consumption models etc,which prondes the effective methods on operating optimal control for engineering building.
