We can adjust some processing parameters to lower single yarn strength CV and improve the quality of rotor spun yarn.

Effective factors on the strength variable coefficient of polyester staple fiber;

Study on resistance to disease and frigid of Jinhua pear varied strains;

Pyrifolia)and its eleven varied strains as testing materials,several good strains of synthetical properties were screened out of the others through the investigation of biological characteristics and the analysis of fruits quality.

Analysis on the variation coefficient of response spectra of earthquake ground motions;

Investigation and Analysis of the Weight Variation Coefficient of the Silkworm Rearing with Artificial Diet;

The variation coefficients between body height and chest circumference were also analyzed.

Boundary Points Detection Algorithm Based on Coefficient of Variation

Relationships between coefficient of variation of diameter and height and competition index of main coniferous trees in Changbai Mountains

Study on coefficient of variation of bone mineral density by Prodigy-DXA measurement

The variance coefficient of gold element is a sensitive indication for recongnition of available level of metalizatioin of rock-gold built in the high gold content area ,and the intensive differentiation is related to regional ge.

Some measurements for decreasing the variance coefficient and improving the evenness of permeability therefore improving the burning ability of cigarette paper are discussed.

Through increased production percent of yield,distinct difference,variance coefficient method,regression coefficient method,high stabilization coefficient method and non parameter tolerance method etc,adaptability of ten new maize varieties are analyzed at four pot of high elevation mountain areas in this paper.
