- unit step input 单位阶跃输入
- For example, a nonlinear system can change from sable to unstable, or vice versa, if the size of step input is doubled. 例如，当阶跃输入的的幅度增大一倍时，非线性系统可能会从稳定变得不稳定；反之亦然。
- By add former feedback in the PID controller the response time of step input reduced form 1.2s to 0.3s. 通过给PID控制器增加前馈环节，使定位时间从1.;2s降低到0

- This paper built a multi-body dynamic model of an air suspension vehicle based on Lagrange's method and performed a ride height simulation under step input using PID and PD control strategy. 摘要以空气悬架车辆为研究对象，通过拉格朗日方程方法建立其多刚体模型，采用PID和PD控制策略，对阶跃输入下的车身高度响应进行了仿真计算和对比分析。
- In the present design, step inputs are restricted to a few tenths of millivolt. 在目前这个设计中;阶跃输入信号限制在零点几毫伏以下.
- Simply inputting one pulse on the STEP input drives the motor one microstep.There are no phase sequence tables, high frequency control lines, or complex interfaces to program. 每次给步进电机一个脉冲信号，电机就会动作一步（整步，半步，四分之一步，八分之一步还是十六分之一步取决于两个逻辑输入）。
- The luminous intensity on unit area. 单位面积上的发光强度。
- When I suggested earlier that combined armies be organized,I meant combining the different units step by step so that,through peace-time training,our men can acquire such knowledge and skills. 刚才我说要编组合成军，就是要逐步地把部队合成起来，通过平时训练，使大家熟悉这方面的知识，学会这方面的本领。
- Sir Alex Ferguson may have his hands full as Manchester United step up their pursuit of an unprecedented second treble, but the manager is already planning enthusiastically for next season. 弗格森爵士现在已定在全力以赴他们史无前例的第二个三冠王，但是球队已经为下赛季准备了。

- The family is the smallest social unit. 家庭是社会最小的单位。
- When I suggested earlier that combined armies be organized, I meant combining the different units step by step so that, through peace-time training, our men can acquire such knowledge and skills. 刚才我说要编组合成军，就是要逐步地把部队合成起来，通过平时训练，使大家熟悉这方面的知识，学会这方面的本领。
- Pressure is force per unit area. 压力就是电单位面积上的力。
- A set of data elements which are handled as a unit. 作为一个单元来处理的一组数据元素。
- If, however, the interval between such step inputs is decreased so that the system never has time to reach the corresponding steady-state, the step representation and Laplace domain are no longer adequate. 但是，如果减小这些阶跃输入的间隔，系统没有足够的时间来到达下一个相应的稳态，则阶跃响应以及拉普拉斯域就显得不合适。
- The family is the basic unit of society. 家庭是社会的基本单位。
