电子车牌的技术优势：数据加密，标签通讯过程中采用独有的算法，第三方设备无法读取;安装简易，无需任何特殊安装工具或材料;独有的人卡、车库编组匹配算法，可以准确判断出非法使用的机动车辆;全天候，可以在任何天气情况下可靠地工作。正是由于电子车牌相比传统车牌有这么多的优势和特点，可以预见在不久的将来，机动车辆将会逐步使用带有电子标签的电子车牌替代目前的传统车牌，这样一来，从车辆前端的电子车牌，到后端的车牌识别、数据传输、车辆管理、数据存储、终端查询等整个平台的构建和发展前景都是十分广阔的，图2是整个平台组成架构的示意图。

湿热法是指用饱和水蒸气、沸水或流通蒸汽进行的方法，以高温高压水蒸气为介质，由于蒸汽潜热大，穿透力强，容易使蛋白质变性或凝固，*终导致微生物的死亡，所以该法的效率比干热法高，是制剂生产过程中*常用的方法。湿热的原理和方法原理湿热的原理是使微生物的蛋白质及核酸变形导致其死亡。这种变形首先是分子中的氢键分裂，当氢键断裂时，蛋白质及核酸内部结构被破坏，进而丧失了原有功能。蛋白质及核酸的这种变形可以是可逆的，也可以是不可逆的。

从这个角度上看，频谱分析仪更适合测量晶体频率。2仪器测量频率的精度从下面两个方面来分析仪器的哪些参数影响到测量精度-内部时钟精度-测量值分辨率初步定性分析，频率计作为*测试设备，内部时钟精度不差，从定期的仪器校验结果看，精度高于1ppm，特别是它的分辨率12bit是非常高的；频谱分析仪的时钟精度看上去也可以，而且1Hz的分辨率满足测试要求，但实际扫描到功率峰值的频率是否稳定还需要验证；而示波器的时钟精度看上去与前两者相差并不大，但需要考虑到：量化误差（前端信号采集系统的8位ADC引起的信号幅度测量误差）引起的垂直电平测量不准确性，以及采样率不足等因素都会引起水平轴的测量误差，*终导致频率值测量误差，而且其分辨率情况需要实测验证。
