离散

Numerical differentiation is that derivative value of a function at a certain point is approximately solved in discrete method.

中文摘要：数值微分就是用离散方法近似地求出函数在某点的导数值，关于数值微分已有许多求解方法，但这些方法都有各自的局限性，并且关于高阶导数近似逼近的方法研究相对较少。

The composite film appeared semitransparent and brown to yellow from optical microscopy. Results show that shorter time sol-heating results in thiner film with less surface roughness, less conglutination to base, and easily to disconnect, while longer time sol-heating results in thicker film with better conglutination to base and worse roughness. RDX distributes in the film everywhere on the whole but discretely on the scale of 2.4 μm according to EDS results. XRD curve of RDX/RF film shows the superposition of RF non-crystal bread curve and RDX crystals diffraction curve. RDX diffraction peaks are broadened and its crystal size is calculated to be lower to 43 nm.

实验所得薄膜半透明，呈棕红色至黄色；实验表明，溶胶恒温加热时间较短时，所得薄膜的单层厚度较小，较平整，但附着力小，干燥后易脱落；恒温加热时间较长时，所得薄膜的单层厚度较大，不易脱落，但表面平整性较差；能谱测试表明，薄膜中的RDX整体上分布较为均匀，但在测试点位间距为2.4μm的微观尺度上呈离散状分布；XRD测试表明，RDX/RF复合物薄膜表现为RF的非晶态馒头峰与RDX衍射峰的叠加，RDX衍射峰明显宽化，其晶粒度可低至43 nm。
