We also analyse environmental factors impacting rubber o-ring: medium under high pressure, high and low temperature, suitability to medium. 文章还从高压介质、高低温环境、与介质的相容性等三方面分析了影响O形橡胶密封圈使用的外部因素。
Based on the microscopic contact force of particles, a phenomenological model for the impacting angle larger than the critical angle is eventually proposed, which accurately describe the nature of resistance force exerted on the projectile by the granular medium during the impacting process. 通过对微观粒子间的接触力的统计分析,提出了一个能够准确描述冲击粒子在颗粒介质运动过程中所受阻力的唯象模型,并对此阻力模型进行了验证。
Ultimately see the main reason of impacting the small and medium IT enterprises on brain drain, and analysis and discuss the results. ( 4) Put forward four suggestions and countermeasures. 最终确定了影响大连中小IT企业人才流失的主要因素,并对结果进行分析与探讨(4)提出建议与对策。
