通过调整这两个参数，可以获得接近零的热膨胀系数。
By adjusting these two parameters, can be near zero coefficient of thermal expansion.
研究表明，采用接近常规的工艺方法和无镀层石墨粉，可以获得石墨分布均匀，价格低廉的铝石墨复合材料铸件。
The results show that the composite castings with graphite uniformly dispersed may be made cheaply by conventional process and by using uncoated graphit3 powder.
