In this paper,an eigenvalue,which and correctly indicates the characteristics of heat transfer and energy-saving in building envelopes,is suggested by analyzing existed non-restrict disadvantages and some engineering problems for the overall heat transfer coefficient.

The linear inner defect tolerances corresponding to the safety graduations are stipulated in " in use pressure vessel inspection stipulation",item 36,table 3.

Methods 90 schizophrenics were classified into deficit(n=27)and nondeficit type(n=63)by the Carpenter s Diagnostic Criterion for Deficit Syndrome,their pre-treatment serum prolactin levels were detected with the radio-immunization and differences of serum prolactin levels of same sex intertype compared,and compared with 30 healthy controls.

The fuzzy clustering method was introduced to ascentain mechanical properties of materials in defect assessment for pressure vessels.

It is suggested that the two equivalent loading methods could be used to calculate the fatigue life of structures loaded with variable amplitude loading in defect assessment.
