The conditions of statistical analysis are assumed,data conversion is discussed,which has pivotal action for statistical analysis under exponent distribution.

Reliability assessment method in the case of zero-failure and few-failure data of liquid rocket engine is mainly researched in this dissertation, and it has carried on the discussion to the method that the reliability data conversion under different operating status.

The paper analyzes research methods, conversion basis, conversion coefficient and adjustment coefficient of quantifying the teachers’ work and how to understand knowledge-based workers should be distributed with the principle of distribution based on their performance and puts forward the author’s opinion.

According to the reliability model and the measurement,a new data conversion was proposed to convert the test data of varied environment into that of the same environment.

To introduce a checking method for varied and small batch wire production——conversion coefficient checking method The method hasgood effect on checking and ratifying the conversion volume of production of equipment and promoting the fulfilment of production pla

To express more directly,conversion coefficient of capacity-temperature K_(a-T) and conversion temperature of effluent gas (T_(py))_(zs) are brought in, to make it easier to compare influence of increasing the temperature of effluent gas on boiler heat loss.

Strength discount coefficient is the major factor influencing the test results of the strength of concrete foundation pile.

Through the regression analyses on natural quality grade index,utilization grade index and economy grade index and their corresponding standard food output,different discount coefficients of different grades are found.

This paper based on the water flow feature and the formula of calculation of energy loss which through plastic supply pipe, determining the convert coefficient that change passing flow quantity into point flow quantity.
