防抱制动系统转鼓试验台架的研制

文中设计并研制的防抱制动系统转鼓试验台架可以对车轮转速、车身速度、垂直载荷、制动管路压力、制动器扭矩等参数进行测量 ,并对由此衍生出的车轮角加速度及减速度、滑移率、地面附着系数、地面制动力等参数进行推算 同时设计了单轮防抱死系统 ,在此台架上进行了试验 ,达到了较好的效果     

Quorum systems for intrusion-tolerance based on trusted timely computing base

Quorum systems have been used to solve the problem of data consistency in distributed fault-tolerance systems. But when intrusions occur, traditional quorum systems have some disadvantages. For example, synchronous quorum systems are subject to DOS attacks, while asynchronous quorum systems need a larger system size (at least 3f+1 for generic data, and f fewer for self-verifying data). In order to solve the problems above, an intrusion-tolerance quorum system (ITQS) of hybrid time model based on trust timel...     

钻孔测温的适时观测

笔者根据××矿区井温测井实际数据的研究和计算认为,近稳态测温在停止井液循环50小时以后进行全井段测温是合适的。对于水文测井,以确定含水层(或段)等为主要目的的井温测井,在停止井液循环12～24小时进行全井段测温可取得满意的结果。
