While the story might be a bit run-of-the-mill for something so ultimately cutting-edge, the dialogue itself is quite often riotously funny.(盡管有些情節由于太過尖刻而顯得一般，然而對話本身還是相當有趣的。)

On the basis of that the diamonds distribute in the impregnated bit homogeneously, the article calculates the cutting depth and the normal force on the protrusion diamond on the crown.(本文以金剛石在孕鑲鉆頭中均勻分布為基礎，從理論上推導出唇面徑向不同位置的金剛石切深、受力。)

It is the key to ensure that PDC bit has choiceness of the work performance to reasonably place cutting.(合理的布齒是保證PDC鉆頭有優良工作性能的關鍵。)

Rock cutting by a step ped bit has been studied with experimental stress analysis and is tested under atmospheric pressure.(本文用平面光彈方法，對階梯金剛石鉆頭切削刃下巖石的應力進行分析。)

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.(在分析各國整體切削具不提鉆可換式鉆頭結構及存在主要問題的基礎上，提出采用整體旋轉切削具可換式鉆頭。)

Diamond cone bit is a new drill bit which make use of cutting cutters interacting with rock slowly and alternately.(輪式金剛石鉆頭是利用切削齒緩慢交替切削運動來破碎巖石的新型鉆頭。)

Such as easy cutting paste, a bit not careful density board they smoke.(譬如容易切割糊，稍不留神密度板就冒煙了。)

The self-feeding bit consists of the rotary nozzle, the cutting conformity device and the power supply device etc.(自進式鉆頭由旋轉噴嘴、鉆屑整合裝置、推力提供裝置等組成。)

Based on the data, this study studies the cutting force affected by the characteristic parameter of PDC cutters, the mechanics property parameter of rocks, the working parameter of PDC bit.(PDC齒切削載荷的分析，以實驗測試的數據為基本依據，對鉆頭布齒結構參數、切削齒特性參數、巖石的力學性質、鉆頭的工作參數等因素對PDC齒切削力的影響規律做了全面、系統的研究。)

In reality, the image is a bit of an illusion: the lightning was far from the Observatory and the laser only appears to be cutting through the bolt.(在現實中，這個圖像相當于一種錯覺：閃電遠離著天文臺，激光似乎切斷了這個閃電。)
