At first , the propagation and influence of stress wave on the top of the pipe pile were discussed in the paper and a formula was obtained about the time difference between two initial signals which were received from two different points 本文首先研究了应力波在管桩顶面的传播及其影响,并提出了计算不同点激励速度峰值时间差的关系式。
Complete the bi - directional data communication between the hardware and the microcomputer . ( 3 ) design the cpld ( complex programable logic device ) processing circuit to preprocess the initial signal in the data acquisition module ( 3 )下位机采集模块部分,在一块cpld ( complexprogramablelogicdevice )集成芯片上烧写了设计的电路,能够对输入原始信号进行预处理。
Arranged signal activating lock circuit and time - base control circuit in the sound wave receiving circuit to take the initial signal of back wave as the valid one in the cycle , thus to improve the ratio of signal vs . noise and detective precision 在超声波接收电路中设有信号触发锁定电路和时基控制电路。实现以各探头中最早收到的回波信号为本检测单元的有效信号,有效提高信噪比和检测精度; 4
The effects of the variations of the initial signal proteins concentrations on the output of this system are also studied . the study demonstrates that the jak - stat signaling pathway is robust with respect to its signal time and signal duration , but sensitive with respect to its signal amplitude 我们主要考察了细胞信号转导过程中三个重要的特征量的变化,即“信号时间” signal time “信号持续时间” signal duration以及信号幅度signal amplitude 。
The temperature sensing circuit adopts current - output mode taking pnp substrate transistor as temperature sensing device . according to the theory of the bgr , ptat and ctat can be generated from the circuit , and the former one is regarded as the initial signal which correlating to the temperature 温度传感电路以衬底pnp型bjt作为感温元件,采用电流输出模式,按照带隙基准原理获得与绝对温度成正比( ptat )电流以及与绝对温度成反比( ctat )电流,并以前者作为与温度相关的原始电信号。
