Determination of multi-elements in superalloy by glow discharge mass spectrometry and interference correction;

Through the comparison observations under the conditions of opening and drying environments by using the qualitative and quantitative filter paper, we are trying to reveal the environmental and artificial interfering factors to the soluble CO_2 during the observing process in the deep spring water.

It is of great importance to study and identify geochemical anomalies caused by some interfering factors and find out the eliminating methods in developing and applying comprehensive oil and gas geochemical exploration techniques so as to recognize the real anomaly information associated with oil and gas activities.

Comprehensive analysis of instable machining state caused by various disturbing factors was given and pertinent solution was presented.

Through collection of TIG welding arc light spectrum of steel with disturbing factor,this paper studied the effect of disturbing factors such as rusty and various gas flow rate on the arc light spectrum distribution.

The methods include building mathematical and simulation model,building disturbing factor’s model and processing data of simulation result,etc.
