While the milling machine is running , you must not adjust the milling speed nor load ( or unload ) the components . milling speed can be changed only when the machine is stopped 铣床运转时不得调整铣削速度，不得装拆零件，如需调整铣削速度，应停车后再进行。
Jeweller harald hardy herzmann , his security guard and a dog were all on the way to meet customers in the austrian winter sports resort of hochgurgl when herzmann stopped nearby , according to local media 案发时，他的保镖和护身犬都下车去了奥地利冬季运动场馆hochgurgl ，而他在附近停车后去小便。
If it were shut down abnormally , the direct economic loss will be at least 300 thousand yuan rmb per hour . even if it switched on immediately after shutoff , the oxygen and nitrogen production can return to normal at least four hours later , and it has to spend seventy - two hours to make liquid oxygen and its purity meet the requirements , in which the losses from half a steelmaking and ironmaking production loads or so are not included 如果非正常停车一次每小时至少直接经济损失30万元，即使停车后马上启动，也至少要4个小时以后氧氮产量才可能恢复正常，液氩产量和纯度要达到要求则需要72个小时，这还不包括炼钢和炼铁要减一半左右生产负荷的损失。
The problem is then fed to a nonlinear programming routine to solve for all parameters . the flight dynamics model with yawing motion of uh - 60a is given , scale factors of state variables and control variables are applied based on the consideration of algorithm convergence . then , the optimization of trajectories is expressed as optimal control problem with a performance index constrained by helicopter performance limits , faa regulation and so on 首先,建立带偏航运动的直升机点质量模型,然后对状态变量和控制变量进行无量纲处理,因为状态变量和控制变量量值相差较大,这使得优化算法收敛效果变差,所以需要选择适当的缩放因子,最后把直升机单台发动机停车后的飞行轨迹表示成一个最优控制问题,即在考虑直升机性能限制和far规范后,指定一个优化性能指标,选择合适的路径约束,然后再解最优控制问题。
