一、前言人们通常习惯于把砂型紧实度作为造型工艺过程中衡量砂型工艺质量的一个指标,然而对砂型质量控制具有重要意义的,则是砂型内部紧实度的分布。尤其是在研究新的紧实方法时,它能确切地表征紧实方法的效果。但是,目前还没有一种较为理想的检测方法和仪器。为了“射砂机构及其参数”课题研究的需要,我们从1981年10月开始进行了静力触探检测砂

First, the preamble People are usually accustomed to the sand compactness as a modeling process to measure the quality of the sand process as an indicator, but for sand quality control is of great significance, the sand is the internal compaction distribution. Especially when studying new compaction methods, it can accurately characterize the effectiveness of compaction methods. However, there is not a more ideal detection method and instrument. In order to “sand body and its parameters,” the research needs of the subject, we started from October 1981 began a static probe to detect sand
