The base of running digital manufacturing system is exact data gathering of tool , equipment , materiel and producing .

数字化制造系统的运行是以准确高效的刀具、设备、物料与在制品等资源的数据采集为基础。

The effects of vacuum volume of materiel and the speed of freeze on quality of finished product were discussed .

并通过对物料冻干曲线的分析，从真空度、物料体积的大小和预冻速度等方面探讨了对冻干速率和冻干成品品质的影响，还测定了冻干品的复水性、得率等。研究发现在一定范围内，真空度越低，冻干速率越慢。
