If no crystals form, scratch the sides of the flask with a glass rod in order to induce crystallization.
如果没有结晶形成，可以用玻璃棒刮一下烧瓶的瓶壁以诱导结晶形成。

The mechanism of this anti-order magmatic evolution is mainly caused by the separate crystallizationof plagioclase in a high-level magma chamber.
这种反序岩浆演化的机制主要是由于斜长石在高位岩浆房中的分离结晶所致。

Additionally a thyristor control will be supplied in order to adjust the slurry concentration in the crystallization system in case of larger variations of the production parameter.
