- After some experimentation, DataSynapse provided the OA with queue depth, the length of time each unit of work was taking, as well as a measure of the current workload. 经过一些实验之后,DataSynapse可以向OA提供队列深度、执行每项任务所需的时间,以及评测当前任务负载的方法。
- Data that focus not on age but on length of service give similar results and confirm that the frequency rate of work accidents decreases with length of service. 事故的次数的多少与人的年龄无直接关系,但与服务的年限的长短有关,事故的频率随著服务年限的增长而减少。
- From whole to blocky and heavily fractured structure, the abutment stress ahead of working face reduces and the peak value of abutment stress migrates to inside of roof rock mass. 过断层后,顶板岩体中支承压力减小,比无断层存在的情况要低。由于顶板岩体中节理发育程度的不同,顶板岩体变形破坏规律和矿压分布各异。表现为由完整到块裂和碎裂结构,老顶的初次垮落步距、周期垮落步距和冒裂带高度均随着岩体破坏程度的增强而减小;顶板岩体中的支承压力亦由大到小变化,且支承压力峰值位置随着岩体破坏程度的增强向顶板岩体内部转移。
