Through simplifying the combustion model of Coal-Water Slurry, the combustion time of Coal-Water Slurry is calculated and the effects on the combustion efficiency of Coal-Water Slurry are analyzed.

Experimental results show that flame propagation speed is proportional to combustion time and the gained width of reaction region from experiments is much greater than one gained from the turbulence theory.

The paper introduces a new method of measuring combustion time with CAT technique for solid rocket engine.

An analytical determination method of the burning time for solid rocket motors;

The relation equation of pressure drop in oil tank vers burning time and the air volume is established.

: Based on productive and experiomental data, the factors affecting the burning timeof safety fuse, such as composition and mixing time of black power and ambient conditions are analyzed and concluded.

Using the method of transition probability flow graphs(TPFG),the average sampling number to signal for these charts is given,and the average time to signal for these charts is deduced.

Because time enters quantum mechanics as a parameter rather than a dynamical operator, people have to consider how to construct a time operator and calculate average time whenever they are faced with a time problem related to a physical process.

This paper presents the successful use of multiple holographic interferometry in realizing the holographic real time double exposure (time average) interferometry.

To improve the performance of energy detection in lower SNR,the time average operation was performed to the train of pulses at the front of the receiver,which can restrain the effect of noise on leading edge detection and the setting of thre.
