The phase separation of glasses of the 17(CaO+MgO)-6Na2O-6AhO3-65SiO2-x(B2O3 +P2O5)(0 ≤ x ≤6) (wt%) series were investigated using DSC, XRD and SEM.The X-ray diffraction (XRD) and differential scanning calorimetry (DSC) showed that there were two amorphous phases in the glasses.

以SiCw和SiCnm两者为增强相,采用热压工艺制备晶须与纳米颗粒混杂增强增韧的ZRC基超高温复合材料,同时对所制备的材料进行组织分析与性能测试.结果表明,SiCw主要是通过裂纹偏转、晶须桥接与晶须拔出等增韧机制;加入SiCnm,在烧结过程中提高复合材料制备时的致密度,通过细晶强化,增加裂纹的扩展,颗粒对裂纹的钉扎以及复合材料内各组分间热膨胀、弹性模量失配途径来提高材料的强韧性.其中75ZrC+1
曲梁结构广泛应用于航空航天、机械、土木等工程实际中,其固有频率和振型的精确预测对于结构设计十分重要。然而,曲率的影响导致了曲线梁结构的运动相互耦合,振动形式复杂,这给动力分析带来了不便。本文基于Timoshenko梁理论,考虑轴向拉伸、横向剪切及旋转惯性作用,采用以NURBS(非均匀有理B样条)为基函数的等几何方法,实现了精确几何的平面曲梁自由振动分析。
轴向运动连续体系统中,其动力学特性呈现为横向振动和不稳定性,横向振动使系统产生不稳定性,限制了它们的应用效果。轴向运动系统的控制方程中含有时间和空间混合偏导数项,是典型的陀螺连续体,运动微分方程中包含着丰富的动力学内容。由于技术流程的要求,在高速运动印刷包装系统中,出现张力的不均匀性是显而易见的,因此必须考虑在非均匀张力作用下,系统会产生的动力学行为。图1 所示,在非均匀张力作用下以恒定速度轴向运
