The macroscopic defects such as twins, small - cracking, scattering particles, growth layer and cores are examined ; they are related with the temperature difference between gas and melt : the twins and small - cracking come out when the difference is large, the bubbles and scattering particles come out when that is small
觀察到了孿晶、裂隙、雲層、生長層和核心等宏觀缺陷，晶體的這些宏觀缺陷與氣- -液界面溫差有較大關系：溫差大容易造成孿晶、裂隙等缺陷；溫差小容易造成氣泡、散射顆粒等缺陷。 -
The authors have observed the progress of deformation and destruction of coal bodies in the experiment, carried out the macroscopic and microscopic research of the destruction progress of coal samples under load by means of servo electro - hydraulic loading test and electromagnetic radiation and audio emission monitoring, analyzed the cracking rate of coal samples under different situation, investigated the formation and development of cracking by use of fracture and elasticity mechanics, and thus established a sound experimental basis for the prediction by using gray classification
摘要進行了煤體變形破壞過程實驗，利用電液壓伺服加載試驗、電磁輻射和聲發射監測手段，從宏觀、細觀、微觀三個方面對煤樣受載破裂過程進行試驗研究，分析煤樣的裂隙發展速度及其所處的不同的狀態，並參照目前的預測方法提出了煤與瓦斯突出危險狀態灰色分類方法。
