A diode-laser system based on this techniques is developed to monitor CH 4 non-intrusively at elevated temperatures,line strengths of the transition in the R(3)band including three extraordinary near lines near 1653.

Based on the perturbation theory,the influences of the Fermi resonance interaction between the two and three vibronic levels on the level energy,wavefunction,and the spectral line intensity are investigated in detail respectively.

It is shown that excitation temperature increases with increasing microwave power,and decreases with increasing gas flux,the spectral line intensity initially increases with increasing microwave power,decreases at 550 W and 700 W,and then increases again.

Relationship between raw cotton property and yarn strength;

Amino-silicone reduces the friction coefficient between fibre to fibre which results in the lowering of cohesion of the fibres and yarn strength.

The method of improving the yarn structure and increasing the yarn strength was found.
