    對各國和地區采用基氏塑性?xún)x測定煤的流動(dòng)度的相關(guān)標準進(jìn)行了研究，美國、日本等國和地區的研究較為完善。比較分析了各國煤的基氏流動(dòng)度測定標準的不同之處，除部件精確度要求有差別外，最主要的不同之處為煤甄坩堝底部中心凹槽坡口角度不同，這就產(chǎn)生了攪拌漿與坩堝底部的不同接觸方式。總結了中國煤的基氏流動(dòng)度測定標準以及基氏流動(dòng)度測定儀研制過(guò)程中存在的主要問(wèn)題及應用、發(fā)展現狀。研究表明，基氏流動(dòng)度的測定尚未有相關(guān)的國家標準，而國內測定儀多為國外進(jìn)口，國內研制的設備精度不高，檢測效率較低；在煤的流動(dòng)度指標應用上，日本等國將其用于指導配煤煉焦、預測焦炭質(zhì)量，而中國也在這些方面逐漸進(jìn)行研究。

    Research the standards of coal Gieseler fluidity tested by Gieseler plastometer in many different countries,which is more advantage in America and Japan.Compare the differences of standards in different countries,found that besides the requirement of parts precision of Gieseler plastometer was slightly different,the primary difference was the angle of V shape notch in the central of crucible base,which would lead to a different contact way of steel stirrer and retort crucible bottom.Summarize the main issues in the process of setting coal Gieseler fluidity,also introduce its application and development.There are no national measuring standards in China to guide the test,the Gieseler plastometers are mainly imported from abroad,the precision of domestic equipments is low.Gieseler fluidity of coal was used for coals blending and predicting the coke quality in Japan and other countries,and similar researches had also been carried out gradually in China
