英文
green sand-
This work carries out a temporal - spatial analysis and comparison in facial pattern, grain - size, and susceptibility of the sediments of the hunshandake sandy land ( hsl ) on the basis of studies of more than fifty geological sections, a number of samples collected from surface sands as well as results derived from previous studies. the preliminary results of this work provide new environmental information of the working area, which makes it possible to have a brief discussion about the evolution of the hsl since the late glacial epoch. this work can be summarized as the followings
晚冰期，渾善達克沙地全面擴張，達到了沙漠化最大規模，剖面中的古風成砂是最直接的證據，此時氣候乾冷；全新世早中期，渾善達克沙地成壤比較好，是一個大面積成壤期，相當于全新世適宜期，此時氣候暖濕；全新世晚期，渾善達克沙地沙漠化正過程加強，在沙地各剖面上普遍發育風沙沉積，氣溫較乾冷；目前：渾善達克沙地為另一成壤期，成壤作用相對于適宜期較差，氣候乾暖。The numerical simulation on green sand molding and core making process helps to forecast the quality of sand mold and sand core, to optimize the molding process and to ensure the quality casting production
