Both the impulse equations of structural dynamics and the solution were established, and the (numerical) stability and accuracy of the integral formulation were also discussed.
The result shows that this mathematical model could give some reasonable guidelines to the formulation design of the thermal insulating coatings and the structural optimization of the cenospheres.
结果表明：该数学模型可用于指导隔热涂料的配方设计以及空心微球的结构优化。
