cutting bit

基本解释

Based on analyses about the structures and existing problems of integrally retractable alternative cutting element bits, a integrally rotary replacing cutting element bit was proposed.
在分析各国整体切削具不提钻可换式钻头结构及存在主要问题的基础上，提出采用整体旋转切削具可换式钻头。
Because coal and rock usually exist together in same section of laneway, on condition that power are constant, when cutting bit cuts the coal, high feeding velocity and low feeding force are needed;
由于在巷道同一断面内通常是煤岩共存，在功率一定的条件下，当截割煤时，需要高进给速度、低进给力；
As the simulation system excludes the restriction of moving conditions and cutting structure of bit in the traditional theoretical analysis, the simulation result is more scientific and reliable.
该仿真系统突破了传统的理论分析方法对钻头运动条件的限制和对钻头切削结构方案的限制，其分析结果的科学性和可信度具有显著提高。

In fact, if the other person is working hard, or is cutting back on their carbon emissions, you have every bit more incentive to not work hard or to keep high carbon emissions yourself.
实际上,如果其他人正在努力工作,或者正在尽量减少碳排量,你总会有想偷懒的动机,或者总是继续大量排碳
