您要查找的是不是：
- unit pulse function 单位脉冲函数
- The pulse function is most suitable for welding plates with different thickness, one formation welding and welding at various position. 脉冲功能最适合焊接不同板厚单面焊双面成型、各种方位的焊接等。
- A recursive formula of the nonlinear observer is derived by using the blok pulse function which can be easily implemented on-line with microcomputer. 文中把方块脉冲函数应用到该非线性观测器,导出一个简单的递推算法,易于微机在线实现。
- Particularly, comparing with other AMS, it also has distinctive advantage in approximation to some discontinuous functions such as rectangular pulse function. 特别在对一些不连续函数（如矩形脉冲函数）的逼近中也有其它AMS无法比拟的优势。
- BECAUSE OF THEIR EXTREMELY short duration, these ultrawideband pulses function in a continuous band of frequencies that can span several gigahertz. 超宽频脉冲的延续时间很短，因此必须在横跨好几GHz的连续频带内运作。结果是，脉冲愈短，占据的频谱愈宽。
- Equivalent load density models for feeders based on pulse function 采用脉冲函数建立馈线等效负荷密度模型
- The luminous intensity on unit area. 单位面积上的发光强度。
