s:Sterilization F value,D value,Z value of canned food are expound by giving some typical examples with the concept conversion coefficient of sterilization time.

After making analysis on the signification and adaptability of some expressions of yield coefficient, it was pointed out that if f value established with primary clarifier was used for engineering design of biological nitrogen and phosphorus removal system without primary clarifier, there would be errors of 40%-60%.

According to W D Bigelow's sterilization theory, a programmable DAQ system based on PC (Personal Computer) open loop was built to provide continuous measurement of cold spot temperature and accumulate its F value during can sterilization process.

This article investigated the anti-fatigue activity of high Fisher ratio oligopeptide derived from egg white protein and the dose-effect relationship by determining the running time on a staff, the content of serum urea nitrogen (SUN) and hepatic glycogen.

The results showed that 5% concentration of high Fisher ratio oligopeptide derived from egg white protein was much better than other material in increasing running time on a staff,increasing the content of hepatic glycogen and decreasing the content of serum urea nitrogen(SUN).

Research and development of a computer-based real-time acquisition and displaying system for food temperature and F value/C value;

Furtherly,the fuzzy integral of nonnegative measurable fuzzy valued functions with respect to fuzzy valued fuzzy measure is studied,and its definition,properties and convergence theorems are shown,such that Sugenos fuzzy integral is extended.

Based on the monitoring data,the groundwater environmental quality in He'nan Province was analyzed by the way of fuzzy comprehensive evaluation,method of "voting down by only one vote" and international F value method.
