So it is very essential to explore new instrument to measure power and frequency of high power pulse microwave 因此,研制功率和频率测量统一于一体的,低成本、小体积且使用方便的便携式大功率脉冲微波仪器具有十分重要的意义。
This approach the problem of conquers phase excursion and frequency drift that anciently adopts fixed frequency filter and its frame is simple 这种方法克服了以往采用固定频率滤波器带来的相移和频率漂移问题，而且结构简单。
To a series of dampings , velocities and frequencies , the linear interpolation is applied and the flutter speed and flutter frequency are obtained 对得到的一系列的阻尼、速度和频率进行了线性插值，从而得到颤振速度和颤振频率。
Volatility is a normality trait of stock market , but it means the gather of risk when the frequency and amplitude exceed certain demarcation 股票市场波动是市场的常态特征，但是波动的幅度和频率超过一定界限，则意味着风险的聚集。
Since the carrier is suppressed , this phase and frequency reference is required for synchronous demodulation of the color information in the receiver 由于载波收到抑制，因此需要这个相位和频率参考来对接收机的颜色信息进行同步解调。
Abdominal pain or discomfort is typically relieved by defecation and associated with change in stool form ( usually looser ) and change in stool frequency 腹痛或者腹部不适通常于排便后缓解，而且与大便形状（通常变松散）和频率的改变相关。
Then simulation and cpe after fft are completed . chapter 5 . the fpga realization of symbol and frequency synchronization is described and its results are given 第五章完成融合方案时域同步模块中符号和频率同步各个模块的fpga实现并给出结果。
Two kinds of typical wideband signal , frequency modulation ( fm ) signal and frequency spread signal , is analyzed qualitatively with wideband ambiguity function 以宽带模糊度函数为工具定性地分析了两类典型宽带信号，即调频信号和频率分集信号。
The influences of potential damping , nonlinear viscous damping , wave heights and wave frequencies in regular beam waves on the safe basin were investigated 分析了非线性横摇方程中势流阻尼、非线性阻尼以及在横向规则波作用下波高和频率对安全池的影响。
Software - practice and experience , mar . 1994 , 24 : 327 - 336 . 13 han d , xiao c , zhou r et al . load shedding for window joins over data streams 分别采用了窗口计数器预估数组和频率数组来维护相应统计信息，并在实际中使用树状数组取代频率数组以提高计算效率
