By controlling combustion temperature or adding kaolin clay to make alkali metal salts into high melting substances, coking can be avoided in dense phase zone.

通过控制密相区燃烧温度或添加高岭土使之与碱金属钠盐形成高熔点物质，可避免密相区结焦。

If the length of melted zone is thought invariable for a given kind of alloy, the temperature gradient increases with the rising of the EB power and zone melting rate.

在不考虑熔区长度不变的条件下，固液界面前沿的温度梯度随抽拉速率的增加而增加。
