Based on the conversation equations for hydrodynamics and chemical reaction dynamics, by adopting the k-e turbulent model and the EBU-Arrhenius combustion model, the SIMPLE algorithm was used to investigate numerically the methane-air premixed gas vented explosion process in the two-dimensional space of the spherical vessel with a conduit for explosion venting.

为了得到球形容器内可燃气体的泄爆强度产生机理以及燃烧火焰与压力传播的基本规律，从流体力学和化学反应动力学守恒出发，采用κ-ε湍流模型和EBU-Arrhenius燃烧模型，利用SIMPLE算法对带泄爆导管的球形容器二维空间内甲烷－空气预混气体的泄爆过程内外场进行了数值计算，获得了气体燃烧过程中火焰和压力传播特性以及气体流动特性，能够比较清晰地反映泄爆的整个过程。

Results Fusarium sambucinum was the main pathogenic bacteria on C. deserticola stem rot which was first recorded; its suitable medium was PSA culture medium; among the carbon and nitrogen sources supplied, saccharose and peptone were most available; the temperature range of its growth was 10-30℃ and it grew best between 6-8 pH value.
