The influence of the process parameters, such as abrasive jet pressure, stand-off distance, number of shots and the nozzle moving speed, on the depth and width of the grooves are revealed. 获得喷射压力、喷射距离、喷射次数、喷嘴相对工件移动速度等工艺参数对刻线深度和宽度的影响规律。
An optimization model of the dryer gear modification coefficient was established while such gear parameters as transmitting ratio, center distance, number of teeth, modulus and width of tooth were kept unchanged. 在保证烘缸齿轮传动的传动比、中心距、齿数、模数、齿宽等参数不变的条件下,建立了烘缸齿轮变位系数优化模型。
Bonding interconnect is the critical technique for realizing the interconnect of microwave multichip module ( MCM ). The height, distance and number of wires of bonding interconnect have important effects on its microwave characteristics. 键合互连是实现微波多芯片组件电气互连的关键技术,键合互连的拱高、跨距和金丝根数对其微波特性具有很大的影响。
The 2 - distance chromatic number of Cartesian product of graphs 笛卡尔积图的2-距离色数
The premixed effect in micro-premixed chamber is investigate using the several factors of fuel inlet diameter, numbers of arc-shaped and straight channel, the distance and number of subordinate fuel inlets. 提出以燃料入口直径,旋、直流槽数量,次级燃料入口距离、数量等几方面因素来研究提高微型燃烧器预混腔的预混效果。
