The thesis introduces the principles of tool setting in CNC lathe,and describes the process of tool setting in detail in FANUC-0i TC system,and illustrates the measures of adjusting tool-compensation which can improve machining accuracy.

Fault diagnosis based on duality principle for systems with time-delay;

Two interval sculling compensation algorithm based on duality principle

Traditionally,duality principle is limited to linear circuits.

Application of Heisenberg correspondence principle in the mesoscopic time-dependent coupled circuits;

The article puts forward and sets out clearly algebraic substitution axiom and the principle of duality, which are both universal logic laws.

Using the principle of duality,the article creatively solves the problem of relationships between planar graphs,connected graphs and dual graphs.

Directed against the features that the objective function and restraint function for the optimal designing problems of gear transmission were constituted by generalized multinomial, and by the use of dual principle let the highly nonlinear planning problems be transformed into the solution of the optimized problems with linear restraint.

On the basis of the study of dual principle,the duality existing universally in nature is brought into study range of the extenics and is considered as a kind of extensionality of the matter element,and then an extensive method named similar-couple method is proposed based the duality.

The study begins with dual principle, from which monopole is introduced and the form of electric charge grotesque potential is applied, and from which the law of conservation of energy is obtained and Dirac s condition of quantification is mutually decisive.

Based on Ya s Circle Guess, we prove return circuit questions of one kind of curve internal zigzag line in theory, and get return circuit relations of curve s some tangents by using principle of duality
