The instability parameters of four oil mixtures which were mixed with different crude oils at different ratio,were determine by using near infrared spectroscopy(NIR) technique.

Application of cultivars stability parameter and high stable coefficient in the analysis of sugarcane regional trial in Yunnan;

The expression of stability parameter H is developed based on the stream function and axial velocity function of Newton helical flow in eccentric annuli with the inner and outer cylinders rotating simultaneously in this paper.

Using the method that is stability parameter,high stability coefficient,average of yield,coefficient of variation and coefficient of regression judged productivity and stability of 17 new maize varieties in Henan Maize Regional Trail in 2003.

But parametric stability test shows that,among the eight consumption expenditure equations that comprise a whole demand system,only the equations for clothing,household facilities and services,transportations and communications,miscellaneous commodities and services,as well as cultural,educational and recreational articles and services have witnessed a local and temporary structural change.

The semi-active optimal control for the parametrically excited instability of a stay cable subjected to a support motion excitation was investigated.
