The results show that amplitude of defect signal is adversely affected by lift-off variations,but phase difference between defect signal and lift-off loci is almost unchangeable.After analyzing the characteristics of the phase difference with the chang of frequency,a conclusion that defect signal is approximately vertical to lift-off noise at a well-selected frequency is obtained.

结果表明提离增加会显著降低缺陷信号的幅值，但并不影响缺陷信号和提离轨迹之间的相位差，通过分析相位差随检测频率的变化规律发现：存在一个合适的频率可使缺陷信号和提离干扰之间出现90°的相位差。

The model of a hydraulic system composed of fluid resistance, fluid capacitance and on/off valve is analyzed. Dynamic model considering fluid resistance and fluid capacitance are set up for on/off valve. Bloc diagram of simulation modules of the hydraulic system is worked out with Matlab/Simulink. The system is simulated through different parameter settings. Influences of fluid resistance and fluid capacitance on flow characteristics of on/off valve are qualitatively analyzed.

This invention discloses an IC phone communication method based on the FSK mode including: loading and transmitting ciphered sequences, ciphered card information, called number information and other interaction information between an IC terminal and a process platform in the mode of FSK information, in which, the platform authenticates the authority and charges, if the deduction at the IC terminal is correct, then it sends signals of anti-stealing making phone calls periodically to the platform, which differentiates the correctness of the signals, if they are wrong, it releases the call, when the communication is finished and the calling rings off first, the platform receives the identification signals of the ring-off of the calling to cut off the call of the called side and release the voice channel between the platform and the called side, then processes balance information and releases the call finally.

本发明公开了一种基于频移键控方式的IC卡电话通信方法，其主要方案是IC卡终端与处理平台之间通过FSK信息方式承载和传输加密序列、加密卡信息、被叫号码信息及其它交互的信息，由处理平台进行鉴权和计费；如果IC卡终端扣费正确则周期性向处理平台发送防盗打信号，处理平台鉴别防盗打信号的正确性，如果错误则释放呼叫；当通信结束后主叫先挂机时，处理平台收到主叫挂机标识信号后首先切断被叫侧的呼叫，释放处理平台与被叫侧之间的话路，然后再进行余额信息的处理和最后释放呼叫。使用本发明提出的方法，使得IC卡终端与处理平台之间的信息交互流程更加简单、清晰，提高了信息交互效率，并能及时释放话路，节约中继资源。
