求翻译：因竖井钻机属超大型设备，无法在实验室内完成实验验证目的，故超大型钻头需按照合理、科学的、一定比例进行缩小来模拟性能实验。是什么意思？

Shaft drilling rig is a very large equipment can not be completed in the laboratory experimental validation purposes, very large drill bit is required in accordance with the rational, scientific, and a certain percentage of narrow to simulate the performance of experiments.

Because it is a very large shaft drilling rig equipment and cannot be done in a laboratory experimental verification purposes, it is an extra-large drill bit required in accordance with reasonable, scientific, and a certain percentage to zoom out to simulate performance lab.

Because the shaft drilling machine is the ultra-large equipment, is unable to complete the experiment in the laboratory to confirm the goal, therefore the ultra-large drill bit must according to reasonable, the science, certain proportion carry on reduces the simulated performance experiment.

Shaft drilling machine is superlarge device could not be completed in the laboratory of experimental verification purposes, Super bit you want to shrink in a rational, scientific, a certain ratio to simulate a performance test.
