计算XRD粉末模式一旦您从结构文件或数据库加载或通过键盘输入所需的晶体结构,您就可以计算其XRD粉末模式了。首先,该粉末模式由一系列可能的反射及其 积分强度I(hkl)表示,使用以下计算: I(hkl)=Kp^2 其中是与X射线束强度相关的缩放常数。由于它通常是未知的,因此I(hkl)被归一化为列表中最强的反射,并报告为相对百...
This article presents a powerful yet simple program, based on the general one-dimensional kinematic X-ray diffraction theory, which calculates the XRD patterns of tailor-made multilayers and thus enables quantitative comparison of measured and calculated XRD data. As the multilayers are constructed ...
1、XRD测出来后对比过石墨层状结构的一个特征峰002的晶面间距,理论上是0.335nm左右,无论是fresh还是反应过后的样品,该晶面距离没有太大的不同, 均在0.335-0.336nm范围。 2、进行过calculate lattice constants,得到a,c的值,听同学说,c/a的值如果偏离fresh越多,说明层状结构发生越大的变化。不知道这个说法是否...
We need to calculate the RTP RTT for: Stats stuff. Better NACK algorithm (see #72). The RTT is calculated from RR and SR. Here some math :

Thanks, Hi Asad, To add the formula we need to have some assumption what are dependencies for the values related to different type of vehicles (or/and day of week, or something else). For example, that could be the assumption what if maximum daily rate is 1 w...

aXRD suggests that these samples are not perfectly ordered but rather are a mix of the pmm2 and LI2 phases. Some success has been had growing these pmm2 films on sapphire substrates under specific temperature ranges (300C–400C). Given the nature of the growth, this phase is not expected...
表明:聚晶金刚石复合片在聚晶金刚石层内存在着宏观应力和微观应力;聚晶金刚石复合片表面应力大小可以反映聚晶金刚石层的应力存在状况;聚晶金刚石复合片残余应力的大小与XRD图谱的斜率成正比,因此XRD方法可以用于聚晶金刚石复合片应力的表征。 5) tress 应力
