这种新的知识是通过岩屑样的显微镜鉴定取得的。
We send herewith a copy of our illustrated catalogue and three sample cuttings
随函寄去我方有插图的目录本一份及三块剪样。
This topic is advanced for the problem of the step motor of the metallographic sample cutting machine
课题是针对金相试样切割机所使用的步进电机存在的问题提出的。
After the setting up and final adjustment of the machine , a sample of stencil will be cut for the comparison with the sample cut in germany and for acceptance of the end customer
设备安装调试完成后，切割样板与出厂样板比较并由最终用户认可(出厂样板如何封样要明确,及出厂样板是否合格如何叛定要明确) 。
The simulation of a practical automotive brake - housing sg iron casting was carried out with the improved model , and the simulation results were verified with the quantitative metallography in several samples cut from the casting
对实际汽车制动臂球铁件进行模拟，并取样进行定量金相实验分析，对模拟结果进行验证。
It's difficult to find sample cutting in a sentence. 用sample cutting造句挺难的

The metallographic sample cutting machine is mainly used to inspect the quality of production and research material science , the step motor , which status influences the quality of the metallographic sample , is the key component to make the moving mechanism run
自动金相试样切割机是用于产品质量检验和材料科学研究的专用设备，步进电机是驱动往复运动机构的关键部件，它的运行状况很大程度上影响切割金相试样的质量。
Although reducer can avoid step sense and oscillation partly , the strap transmission will influence orientation precision ( it is key norm to the small metallographic sample cutting machine ) , so plan to use step motor to drive the screw directly , the step motor at low velocity , which is not drived by the subdividing drive system , will have obvious oscillation and noise that would influence the cutting function , the usage life and sample structure
由于步进电机是通过皮带轮减速来驱动丝杠，进而带动砂轮片前进和后退，虽然减速能部分消除步进感和振动，但皮带传动会影响定位精度，定位精度对精密切割机十分关键的技术指标。采用步进电机直接驱动丝杠，未经细分驱动的步进电机在低速运行时，有明显的步进感、振动和噪声，从而对切割的性能、砂轮片的使用寿命、试样的组织结构产生较大的影响。
