1) impact-friction spark
撞击摩擦火花
1.
Based on the the fully-mechanized top-coal caving mining of 8~# coal bed in Kangjiatan coal mine,the probability of the gas explosion induced by the impact-friction sparks during roof collapse was studied with the special designed experimental instruments.
针对康家滩煤矿8#煤层综放开采条件,采用专门设计的实验装置对其顶板冒落撞击摩擦火花引爆瓦斯的可能性进行了实验研究。
3) Friction spark
摩擦火花
1.
The model of heat conduction caused by friction spark can be regarded as forced convection heat conduction issue of grazing spheriform which is outside of planar stable state boundary layer,so the mathematics analytic formula is presented and a few measures for preventing friction spark.
摩擦火花传热模型可看做是二维稳态边界层外掠球体的强制对流传热问题。
4) Collid-rubbing
碰撞摩擦
5) frictional collision
摩擦碰撞
1.
The frictional collision of multi-rigid-body systems is studied.
研究了多刚体系统的摩擦碰撞问题。
6) impact friction
冲击摩擦
1.
Initial amplitude is recorded and the impact friction coefficient is computed during an impact process.
冲击摩擦为接触面切向与法向冲量之比。
2.
The oblique elastic impact friction model presented by Chen Danian is symmetrically simplified.
将ChenDanian等人提出的弹性斜冲击摩擦模型进行了对称简化,用简化模型分析了粒子对弹性涂层冲击过程中摩擦系数的变化规律及其对涂层冲蚀率的影响;结论指出,在冲击接触的中间时段摩擦系数达到一个平台值(最大值),且有fmax=ctgα0,一次冲击全过程的平均值fp与试验值接近;随着初始入射角α0的增加,摩擦系数降低。
补充资料:真空火花
分子式:
CAS号:
性质:有些元素的发射谱线在远紫外区。卤素、碳、硫、磷等用光谱分析时就需要在近真空条件下进行。真空火花光源是在气氛压力极低的情况下激发放电,用在真空紫外光谱区域中的光谱学研究。它可激发高激发电位元素谱线和一般元素的高次离子谱线。
