With the test data collected by the three-dimensional laser image scanner and total station, the three-dimensional laser scanning image combination model was figured out by the indirect adjustment model with constraint condition.

This paper discusses the various forms of equilibrium equations and the related constraint conditions for conplanar forces and space forces.

Adaptive stick-gain and software rate limit were developed to minimize the phase lag induced by rate limiting.

In the light of the restricted condition under control which system signal operates,the authors put forward an engineering oriented method for designing internal mold controller.

Whether the n has satisfied the restricted condition is dependent on the parameter p .

But because there are a few of restricted conditions, the process can t be finished in short time.

To solve the problem of spatial clustering in the presence of obstacles,an algorithm named spatial clustering with constraints is developed on the basis of traditional K-medoids algorithm.

The functionally correlative connected parameters being equivalent to have constraints between these make that their cofactor matrix become rank defect and its Cayley inverse P′ 2 =Q -1 ′ 2 dose not exist.

This paper, applying the constraints, derives functionally correlative unknown parameters expressed as the functions of functionally uncorrelative unknown parameters.

The approach to the shortest path algorithms with restrictive conditions;

According to the equilibrium equations, which are analytic descriptions of necessary conditions and sufficient conditions in system of forces, the various forms in equilibrium equations of system of forces and restrictive conditions are described completely.

Through the discussion of the pragmatic characteristics and restrictive conditions of vague language,we can improve the appropriateness and suitability of using it,which can guarantee the smooth communication.
