According to the question of actual mining, existing in edge soft friable coal seam, tunnel arrangement and actual process must be changed, so as to reach the target of safe production and lift work efficient 针对某些急倾斜松软破碎结构煤层在采用柔性金属掩护支架回采过程中存在的具体问题,指出必须改变巷道布置和回采工艺,才能达到安全生产和提高工效之目的
How to improve the teaching efficiency through the teachers 'classroom teaching behavior is one of the focuses of the education realms in present. In actual teaching it is very difficulty that teachers lift to ask. 在讲求效率的今天,如何通过提问等教师的课堂教学行为来提高教学效率,已成为业内焦点之一,在实际教学中,教师提问的操作难度很大。
The system which based on the static mathematical model of LD's smelting converter and combined with the actual converter-smelting of steel factory is developed to optimize, decrease the reblow, lift the molten steel quality and degrade the cost. 本系统根据LD转炉冶炼的静态数学模型,结合钢厂的转炉冶炼实际生产条件,进行优化改进,减少补吹,提高钢水质量和降低成本。
The theory of pump adjustment is to determine the working condition according to the actual lift required by the reference point. 它是通过控制点需要的实际扬程所传递的参数信号来确定泵的工况;
Monitor system of safe supervisory system can reality show the parameter of moment percentage of both main hook and auxiliary hook, actual load force, lift angle, actual load height and load range. 安全监测系统的显示系统可随时显示主钩和副钩的作业力矩百分比、实际载荷、主臂仰角、实际起吊高度、以及作业幅度等参数;有预报警、超限报警和超限控制功能。
According to the actual project, this paper mainly studies the motion response of the lift with the state of mooring and lifting. 本文根据工程实际情况,以起重船在系泊状态下起重作业状态为例,对其运动响应进行研究分析。
