Basing on the production experiences,we analyse the suitable hearth inside diameter and pole centre circle diameter,and the suitable burden ratio at various temperatures.

Influence of electrode diameter on EHD enhancement of condensation heat transfer inside vertical tube;

The effect of the discharge electrode diameter on the ozone formation rate was greater than that of the point-to-plate distance of the two electrode.

Under the same spray pressure and the liquid medium,five electrode diameters with different sizes and different installation positions are selected for injection charging spray.

The nonparametric kernel density theory and methods are introduced to model the diameter distribution of broadleaved Pinus koraiensis in Liaoning eastern mountains in contrast with the normal distribution and Weibull distribution.

stand for water resource conservation,the growth process and diameter distribution characteristic of Larix Principis-rupprechtii Plantation in 10 years old were studied using stem analysis method of sample tree,which had two density structures(one was 2 600 per hm2,the other was 3 500 per hm2) in water conservation forest region of Wutai Mountain in Shanxi Province.
