材料分析方法课后答案(更新至第十章)
材料分析方法课后练习题参考答案 2015-1-4 BY：二专业の学渣 材料科学与工程学院
3.讨论下列各组概念的关系 答案之一 (1）同一物质的吸收谱和发射谱； 答：λk吸收〈λkβ发射〈λkα发射 (2）X射线管靶材的发射谱与其配用的滤波片的吸收谱。 答：λkβ发射（靶）〈λk吸收(滤波片)〈λkα发射（靶）。任何材料对X射线的吸收都有一个Kα线和Kβ线。如Ni 的吸收限为0.14869 nm。也就是说它对0.14869nm波长及稍短波长的X射线有强烈的吸收。而对比0.14869稍长的X射线吸收很小。Cu靶X射线:Kα=0.15418nm Kβ=0.13922nm。 (3）X射线管靶材的发射谱与被照射试样的吸收谱。 答：Z靶≤Z样品+1 或Z靶>>Z样品 X射线管靶材的发射谱稍大于被照射试样的吸收谱，或X射线管靶材的发射谱大大小于被照射试样的吸收谱。在进行衍射分析时，总希望试样对X射线应尽可能少被吸收，获得高的衍射强度和低的背底。 答案之二 1）同一物质的吸收谱和发射谱； 答：当构成物质的分子或原子受到激发而发光，产生的光谱称为发射光谱，发射光谱的谱线与组成物质的元素及其外围电子的结构有关。吸收光谱是指光通过物质被吸收后的光谱，吸收光谱则决定于物质的化学结构，与分子中的双键有关。 2）X射线管靶材的发射谱与其配用的滤波片的吸收谱。 答：可以选择λK刚好位于辐射源的Kα和Kβ之间的金属薄片作为滤光片，放在X射线源和试样之间。这时滤光片对Kβ射线强烈吸收，而对Kα吸收却少。 6、欲用Mo 靶X 射线管激发Cu 的荧光X 射线辐射，所需施加的最低管电压是多少？激发出的荧光辐射的波长是多少？ 答：eVk=hc/λ Vk=6.626×10-34×2.998×108/(1.602×10-19×0.71×10-10)=17.46(kv) λ0=1.24/v(nm)=1.24/17.46(nm)=0.071(nm) 其中h为普郎克常数，其值等于6.626×10-34 e为电子电荷，等于1.602×10-19c 故需加的最低管电压应≥17.46(kv)，所发射的荧光辐射波长是0.071纳米。 7、名词解释：相干散射、非相干散射、荧光辐射、吸收限、俄歇效应 答：⑴当χ射线通过物质时，物质原子的电子在电磁场的作用下将产生受迫振动，受迫振动产生交变电磁场，其频率与入射线的频率相同，这种由于散射线与入射线的波长和频率一致，位相固定，在相同方向上各散射波符合相干条件，故称为相干散射。 ⑵当χ射线经束缚力不大的电子或自由电子散射后，可以得到波长比入射χ射线长的χ射线，且波长随散射方向不同而改变，这种散射现象称为非相干散射。

材料分析方法课后习题答案
第十四章 1、波谱仪和能谱仪各有什么优缺点 优点:1）能谱仪探测X射线的效率高。 2）在同一时间对分析点内所有元素X射线光子的能量进行测定和计数，在几分钟内可得到定性分析结果，而波谱仪只能逐个测量每种元素特征波长。 3）结构简单，稳定性和重现性都很好 4）不必聚焦，对样品表面无特殊要求，适于粗糙表面分析。 缺点：1）分辨率低。 2）能谱仪只能分析原子序数大于11的元素；而波谱仪可测定原子序数从4到92间的所有元素。 3）能谱仪的Si(Li)探头必须保持在低温态，因此必须时时用液氮冷却。 分析钢中碳化物成分可用能谱仪；分析基体中碳含量可用波谱仪。 2、举例说明电子探针的三种工作方式（点、线、面）在显微成分分析中的应用。 答：(1)、定点分析：将电子束固定在要分析的微区上用波谱仪分析时，改变分光晶体和探测器的位置，即可得到分析点的X射线谱线；
用能谱仪分析时，几分钟内即可直接从荧光屏（或计算机）上得到微区内全部元素的谱线。 (2)、线分析：将谱仪（波、能）固定在所要测量的某一元素特征X射线信号（波长或能量）的位置把电子束沿着指定的方向作直线轨迹扫描，便可得到这一元素沿直线的浓度分布情况。改变位置可得到另一元素的浓度分布情况。 (3)、面分析：电子束在样品表面作光栅扫描，将谱仪（波、能）固定在所要测量的某一元素特征X射线信号（波长或能量）的位置，此时，在荧光屏上得到该元素的面分布图像。改变位置可得到另一元素的浓度分布情况。也是用X射线调制图像的方法。 3、要在观察断口形貌的同时，分析断口上粒状夹杂物的化学成分，选用什么仪器用怎样的操作方式进行具体分析 答：（1）若观察断口形貌，用扫描电子显微镜来观察：而要分析夹杂物的化学成分，得选用能谱仪来分析其化学成分。 (2)A、用扫描电镜的断口分析观察其断口形貌：

材料现代分析方法试题5 材料学院材料科学与工程专业年级班级材料现代分析方法课程200—200学年第学期（）卷期末考试题（ 120 分钟） 考生姓名学号考试时间 题号得分分数 主考教师：阅卷教师： 材料现代分析方法试题5（参考答案） 一、基本概念题（共10题，每题5分） 1．若X射线管的额定功率为1.5kW，在管电压为35kV时，容许的最大电流是多少？ 答：1.5kW/35kV=0.043A 2．证明（）、（）、（）、（01）、（12）晶面属于[111]晶带。 答：根据晶带定律公式Hu+Kv+Lw=0计算 （）晶面：1×1+1×+0×1=1—1+0=0 （）晶面：1×1+1×+1×1=1—2+1=0 （）晶面：×1+2×1+1×1=（—3）+2+1=0 （01）晶面：0×1+×1+1×1=0+（—1）+1=0 （12）晶面：1×1+×1+1×2=1+（—3）+2=0 因此，经上五个晶面属于[111]晶带。 3．当X射线在原子例上发射时，相邻原子散射线在某个方向上的波程差若不为波长的整数倍，则此方向上必然不存在放射，为什么？
答：因为X射线在原子上发射的强度非常弱，需通过波程差为波长的整数倍而产生干涉加强后才可能有反射线存在，而干涉加强的条件之一必须存在波程差，且波程差需等于其波长的整数倍，不为波长的整数倍方向上必然不存在反射。4．某一粉末相上背射区线条与透射区线条比较起来，其θ较高抑或较低？相应的d较大还是较小？ 答：背射区线条与透射区线条比较θ较高，d较小。 产生衍射线必须符合布拉格方程2dsinθ=λ，对于背射区属于2θ高角度区， 根据d=λ/2sinθ，θ越大d越小。 5．已知Cu3Au为面心立方结构，可以以有序和无序两种结构存在，请画出其有序和无序结构[001]晶带的电子衍射花样，并标定出其指数。 答：如图所示： 6．（1）试说明电子束入射固体样品表面激发的主要信号、主要特点和用途。（2）扫描电镜的分辨率受哪些因素影响? 给出典型信号成像的分辨率，并说明原因。（3）二次电子（SE）信号主要用于分析样品表面形貌，说明其衬度形成原理。（4）用二次电子像和背散射电子像在显示表面形貌衬度时有何相同与不同之处? 答：（1）背散射电子:能量高；来自样品表面几百nm深度范围；其产额随 原子序数增大而增多.用作形貌分析、成分分析以及结构分析。 二次电子:能量较低；来自表层5－10nm深度范围；对样品表面状态十分敏感.不能进行成分分析.主要用于分析样品表面形貌。
