21、ajor problem and foster advantage industry,and adjustment agricultural structure,and carried 第一章1什么是传感器？它由哪几个部分组成？分别起到什么作用？解：传感器是一种以一定的精确度把被测量转换为与之有确定对应关系的、便于应用的某种物理量的测量装置，能完成检测任务；传感器由敏感元件，转换元件，转换电路组成。敏感元件是直接感受被测量，并输出与被测量成确定关系的物理量；转换元件把敏感元件的输出作为它的输入，转换成电路参量；上述电路参数接入基本转换电路，便可转换成电量输出。2传感器技术的发展动向表现在哪几个

22、方面？解：（1）开发新的敏感、传感材料：在发现力、热、光、磁、气体等物理量都会使半导体硅材料的性能改变，从而制成力敏、热敏、光敏、磁敏和气敏等敏感元件后，寻找发现具有新原理、新效应的敏感元件和传感元件。（2）开发研制新型传感器及组成新型测试系统 MEMS 技术要求研制微型传感器。如用于微型侦察机的CCD 传感器、用于管道爬壁机器人的力敏、视觉传感器。研制仿生传感器 研制海洋探测用传感器 研制成分分析用传感器 研制微弱信号检测传感器（3）研究新一代的智能化传感器及测试系统：如电子血压计，智能水、电、煤气、热量表。它们的特点是传感器与微型计算机有机结合，构成智能传感器。系统功能最大程度地用软件实现

23、。（4）传感器发展集成化：固体功能材料的进一步开发和集成技术的不断发展，为传感器集成化开辟了广阔的前景。（5）多功能与多参数传感器的研究：如同时检测压力、温度和液位的传感器已逐步走向市场。3传感器的性能参数反映了传感器的什么关系？静态参数有哪些？各种参数代表什么意义？动态参数有那些？应如何选择？解：在生产过程和科学实验中，要对各种各样的参数进行检测和控制，就要求传感器能感受被测非电量的变化并将其不失真地变换成相应的电量，这取决于传感器的基本特性，即输出输入特性。衡量静态特性的重要指标是线性度、灵敏度，迟滞和重复性等。1）传感器的线性度是指传感器的输出与输入之间数量关系的线性程度；2）传感器的灵

24、敏度S 是指传感器的输出量增量 y 与引起输出量增量 y 的输入量增量x的比值；3）传感器的迟滞是指传感器在正（输入量增大）反（输入量减小）行程期间其输出-输入特性曲线不重合的现象；精品资料-欢迎下载-欢迎下载 名师归纳-第 1 页，共 17 页 -is one of the practical form of values.The so-called values refers to the objective things are of no value and the value of fundamental perspective.Different values,peoples be

45、、不需要的变化。漂移包括零点漂移和灵敏度漂移等。传感器的动态特性是指其输出对随时间变化的输入量的响应特性：频率响应、时间常数、固有频率和阻尼比等。1）瞬态响应特性：传感器的瞬态响应是时间响应。在研究传感器的动态特性时，有时需要从时域中对传感器的响应和过渡过程进行分析。这种分析方法是时域分析法，传感器对所加激励信号的响应称瞬态响应。常用激励信号有阶跃函数、斜坡函数、脉冲函数等。2）频率响应特性：传感器对正弦输入信号的响应特性，称为频率响应特性。频率响应法是从传感器的频率特性出发研究传感器的动态特性。为了减小动态误差和扩大频率响应范围，一般是提高传感器固有频率n。4某位移传感器，在输入量变化5 m

46、m 时，输出电压变化为300 mV，求其灵敏度。解：其灵敏度3330010605 10UkX第二章1什么是应变效应？什么是压阻效应？什么是横向效应？解：应变效应，是指在导体产生机械变形时，它的电阻值相应发生变化。压阻效应，是指半导体材料在某一轴向受外力作用时，其电阻率发生变化的现象。横向效应，是指将直的电阻丝绕成敏感栅后，虽然长度不变，应变状态相同，但由于应变片敏感栅的电阻变化较小，因而其灵敏系数k 较电阻丝的灵敏系数k0小的现象。2、试说明金属应变片与半导体应变片的相同和不同之处。解：金属应变片由敏感栅、基片、覆盖层和引线等部分组成。金属电阻应变片的敏感栅有丝式、箔式和薄膜式三种。箔式应变片

47、是利用光刻、腐蚀等工艺制成的一种很薄的金属箔栅，其优点是散热条件好，允许通过的电流较大，便于批量生产，可制成各种所需的形状；缺点是电阻分散性大。薄膜式应变片是采用真空蒸发或真空沉淀等方法在薄的绝缘基片上形成0.1 m 以下的金属电阻薄膜的敏感栅，最后再加上保护层。它的优点是应变灵敏度系数大，允许电流密度大，工作范围广。半导体应变片是用半导体材料制成的，其工作原理是基于半导体材料的压阻效应。半导体应变片的突出优点是灵敏度高，比金属丝式应变片高5080 倍，尺寸小，横向效应小，动态响应好。但它有温度系数大，应变时非线性比较严重等缺点。3、应变片产生温度误差的原因及减小或补偿温度误差的方法是什么？精
