As the temperature increases, content of quartz, anhydrite, and hematite in coal ash decrease in reducing conditions and some new mineral phases are formed during heating process. The content of mullite formed in the heating process is the mayor reason of high melting temperature of the ash. Anorthite at high temperature lowers the ash fusion temperature.

随着温度的升高，煤灰中石英、硬石膏、赤铁矿等结晶矿物含量逐渐减少，生成新的矿物质，莫来石的生成是导致淮南煤灰熔点高的主要原因，钙长石起到降低灰熔点的作用。

The rule of austenite re-crystallization plays a very important role for the actual production process control.

奥氏体再结晶规律对于实际生产中控制工艺起着非常重要的作用。

METHODS: Using tissue culture technique, the maximal non-toxic concentration of luteolin in swine testicle cell culture was measured, and the inhibitory effect of luteolin on TGEV was measured by cytophathogenic effect observation and crystal violet measurement. In addition, the degrees of inhibition of the luteolin on CPE of virus in cell culture were observed by changing sequence of adding the vires and the drag. RESULTS : The maximal non-toxic concentration of luteolin was 873.39 μmol/L.

采用细胞培养法，通过结晶紫摄入量测定结合细胞病变作用，观察木犀草素在不同的加药方式下，对感染TGEV的猪睾丸细胞的保护作用、结果：TGEV病毒先吸附ST细胞再加入药液，先与TGEV病毒孵育再接种于卯细胞，或药液先与细胞孵育再用病毒感染等不同方式下，木犀草素在0.84-54.50μmaol／L浓度范围内，均能明显地提高细胞的存活数。
