The first one employs the fracture parameter, being the distance from the point of applying the indentation load to the specimen edge.
第一个采用了断裂参数，是距离的应用压痕负荷的标本优势。
Nowadays, in China HVAC systems operate at fixed load, fixed working point and fixed controller parameter, and there are many problems in energy management.
目前，我国暖通空调控制系统按照定负荷、定控制回路工作点、定控制器参数运行，并且在能量管理功能方面有很多不足。
