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。

In this paper, the modeling theory of multi-rigid-body dynamics was thoroughly investigated in order to make up the shortcoming in the above modeling method. The major research achievements are as follows:①Based on the matrix of direction cosine between the body-fixed base and the reference base, and Poisson equation of a rigid body rotating, the coordinate transformation method for the modeling of treelike multi-rigid-body dynamics is derived. The method is very routinization and easy to use the computer to carry on the symbol derivation.

本文针对上述建模方法存在的不足，深入地研究了多刚体系统动力学的建模方法，并将所研究的新方法应用于惯性振动设备的建模，取得的主要研究成果如下：①基于刚体连体基关于参考基的方向余弦矩阵和刚体转动的Poisson方程，导出了建立树形多刚体系统动力学方程的坐标变换法，其过程极其程式化，便于利用计算机进行符号推导。
