The safe distance of dynamic compaction to the exiting structures was determined according to the measurements of vibrating speed , vibrating acceleration , foundation displacement and deformation of structures 通过振动速度、振动加速度、地基位移、建筑物的变形等项目的监测来确定强夯的安全距离。
He said one of the biggest challenges facing coalition and iraqi troops is dealing with the home - made explosive devices used by terrorists and insurgents that can be detonated from a safe distance 他说盟军和伊拉克军队面临的最大挑战是如何对付被恐怖分子和起义军利用的当地爆炸装置，这些装置可以在安全距离内被引爆。
Because wake vortices can persist in calm air for several minutes ( extending for as far as eight miles ) , the federal aviation administration requires minimum distances between aircraft , based on size 机尾涡流可以在无风的空气中停留几分钟，向后延伸达12公里，所以美国联邦航空总署按照飞机大小而规定了飞机之间的最小安全距离。
Article 34 the workshops , stores , warehouses that produce , manage , store or use hazardous substances may not be located in the same building as the dormitories of the employees , and there should be a safe distance between them and the dormitories 第三十四条生产、经营、储存、使用危险物品的车间、商店、仓库不得与员工宿舍在同一座建筑物内，并应当与员工宿舍保持安全距离。
According to the relationship of the scanning scope of robots , the local range of robot motion planning , and the safety distance in an ideal state , it discusses the prohibiting area and the potential collision area in the moving courses of the robots 根据理想状态下机器人的扫描范围、机器人规划的局部范围、安全距离之间的关系探讨了机器人运动过程中的禁入区、潜在的碰撞区。
In designing of air cooling generators , the problem that the generator lead - out can ' t suffice the electric safety distance in the special cooling wind path were introduced , and some measures to the problem were put forward 摘要介绍了空气冷却发电机组的电气设计中，发电机引出线在冷却风道这一特殊区段内，极容易发生不能满足电气安全距离需求的情况，提出了解决这些问题的一系列措施，供设计中借鉴。
Your stopping distance is still the only really safe gap but a reasonable rule to apply in good conditions is a gap of one metre for each 2 km h of your speed or a two - second time gap - more if you are driving a heavy vehicle - may be enough 在这种情况下，停车距离仍是唯一的安全距离。不过，在各方面都良好的情况下驾驶，合理的行车距离，是按时速每2公里便预留1米车距，或预留两秒距程。如驾驶重型车辆，或须预留更大的距离。
Secondly , , we study an improved nagel - schreckenberg model with open boundary condition . we analyze the influence of the boundary condition 、 safety distance and deceleration probability to the traffic flow . thirdly , we propose the three branch road modle without control for the confluence phenomena of cars 接着，研究了一种改进的ns模型在开放边界条件下，安全距离，刹车概率，延迟起动对交通流的影响，较为准确的再现了真实交通中的大尺度堵塞及缓解现象。
