In order to settle the traditional tool s problems of limited precision and applicability, the technique of tractor crankshaft synthetic measurement based on virtual instrument is introduced.

With the rapid development of manufacture technologies, the synthetic measurement of profile with large range and high precision has become more and more imminent.

Application of Comprehensive Forecast of Lithological Traps in Hydrocarbon Exploration;

Calculation error of comprehensive forecast model put forward is smaller than that of single model,and forecast result is,comparatively ideal,which is a relative efficient way of forecast of population growth.

Therefore,integrated monitoring of resources and ecological conditions of the forest and evaluation of the benefit were required.

This paper introduces the functional structure,design and realization of the integrated monitoring & analysis system for the technical condition of the mechanic and electronic equipments in navy ship,as well as its applied effects and conditions compared with those dommestically and abroad.

The paper introduced the concepts and connotation of sustainable forest management,discussed the dialectic relationship of sustainable forest management and integrated monitoring of forest resource,and summarized the current status and development trends of forest resource monitoring in the world.
