From the aplication of the double tracer technique to a mine in Huainan suc cessfully for the first time, it is proved that it is feasible to dectect the ventilation leakage of gob.

Multiple regression analysis on gas-leakage diffusion simulation by using tracer technique;

The research was based on the experiment platform of oil-gas storage and transportation security in Jiangsu polytechnic university,and it was simulated to the whole course of harmful gas-leakage diffusion using tracer technique.

A tracer technique was used to study the stability of liquid surfactant membrane.

The principle of ion-selecting electrode tracer technology and its testing process are introduced in detail in the paper.

In this article, two of the classical applications of gaseous tracer technology, with SF6 as tracer gas, in the dynamic leakage detection of a inter-explosion experimental case and in the overall leakage detection of a nuclear reactor hall were described at large.

The improving direction of tracing technology in chemical engineering was advanced.

This paper majors in the slagging of a 670t/h pulverized boiler, using advanced tracing technology to carry cold modularization experiment, studies the characteristic of aerodynamic field at six corner burner region, analyzes the reason of slag, and puts forward reform scheme.

With wide application of molecular biology and rapid development of radionuclide tracing techniques,radionuclide tracing molecular functional measurements and targeted treatment application became a new force and more and more popular and widespread.

Using chloride ion tracer method to estimate the vertical infiltration recharge of groundwater in arid and semi-arid region has important theoretic and practical value for exploring spatial variation rule of groundwater recharge and improving evaluating theory and method for groundwater resources.
