烧成收缩 meaning in English

firing shrinkage

Test method for properties of investment casting ceramic core - part 2 : determination of sintered shrinkage
熔模铸造陶瓷型芯性能试验方法第2部分:烧成收缩率的测定
The smaller the ratio of nh3 / teos is more helpful for the synthesis of samples . the contraction from calcination of samples obtained in eda medium is proporational to the ratio of eda / teos at room temperature . the samples obtained in mixed basic media ( naoh / tea ) have thicker wall and more thermal stability than in naoh medium , but pore size is smaller correspondingly
氨水介质中， nh _ 2 teos值在( 8 ， 25 )之间越小，越有利于mcm - 41的室温合成；室温条件下eda介质中得到样品的烧成收缩量与eda teos的值成正比;与naoh介质相比，混合介质( na0h三乙醇胺)中水热合成的样品具有较厚的孔壁，有着更好的水热稳定性，但同时孔径相应较小。
