英语语法分析

A displacement sensor based on solenoid principle is used to measure green sand compactibility and mould compaction.

基于螺线管原理的位移探测器用于完成型砂紧实率及铸型紧实度的快速检测。

PRINCIPLE Concrete is placed into a mould and compacted by a rammer. The amount of consolidation is expressed as a compactibility index.

原则将混凝土装入模具中，并用夯实机夯实。固结量即称为“压塑性指数”。

After the first water addition, we adopt AR model to predict the stable value of sand compactibility to shorten the time mixing the sand.

第一次加水后，对型砂紧实率稳定值采用AR模型进行预测，以缩短型砂混制时间。
