Based on the thermal guide theory, we analyzed the melting progress with the cylindroid model in the optical fiber LPHVD (laser plasma hybrid vapour deposition) process.
利用热传导理论，结合LPHVD工艺，在圆柱体模型基础上分析了光纤工艺中激光熔融过程。

This paper propose the analytical solve of effective factor of one-dimensional cylindroid catalyst, which takes an one-order inreversible reaction, by using special functions.
According to the structural feature of parallel single disk gate valve, the strength and rigidity of body will be calculated with finite element method, and with cylindroid shell theory.
