The average coking time can provide the basis for determining oven temperature,maintenance time and maintenance frequency.

)as the example,this paper makes overall analysis and study on the safe operating techniques for extending the coking time in the course of the production from two aspects of extending the coking time and recovering the production.

This paper expounds how to use coke oven rightly so as to prolong furnace service life from aspects of coking time, materials of production, operation, iron piece of protecting furnace, adjustment of temperature and pressure, and treatment of graphite, etc.

Very conclusive document for the influence of coal blend characteristics and coke mass temperature on coke quality are available,however,the influence of carbonization time has not been addressed adequately.

The temperature changing principle of span hole and the regenerator-top in a change-over time and coking period is measured and compared.

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.
