Comparative studies of ZH1105W diesel engine are computed on the joined fuel droplet size and velocity number distributions between diesel and mixed liquefied petroleum gas(LPG)/diesel sprays by using Jaynes s formula.

Surface morphology of the Si film was observed by scanning electron microscopy(SEM) and was found that the average size of Si nanoparticles prepared in different gas all increased initially and then decreased with distance between the target and the substrate increasing.

The average size estimation is an important way to control production quality in many fields, however, the method of traditional measurement by hand is very difficult to meet to the continual mechanized manufacture.

A population balance model for the description and prediction of the drop size distribution in turbulent agitated reactors is developed.

Nondestructive evaluation of average grain size of coarse grain materials based on ultrasonic transmissive technique;

The influence of current density on the microstructure such as average grain size and texture of Ni coatings was studied as well.

The average grain size and microstructure of the nickel nanocoatings heated at different temperature for 2 h and Ni/carbon nanotube composite nanocoatings were examined by X-ray diffractometer(XRD),and their wear behaviour and microhardness were investigated.
