   這些多功能的成年牙齒干細胞，勢必可加速利用支架來制造牙齒的工作，而且也可能促成了英國倫敦國王學(xué)院夏普團隊所進行的牙齒工程研究。
2. 5 ) using the practical products, we have done experiments and comparisons on designing and generating tooth, testing the contact ratio, tooth root stress, vibration and noise for the high contact ratio spiral bevel gears
   摘要5）采用實驗研究技術(shù)，結(jié)合實際產(chǎn)品，進行了高重合度弧齒錐齒輪的設(shè)計、切齒、重合度測試、齒根應(yīng)力測量、振動和噪聲測量等大量對比實驗。
3. abstract : in order to solve the double parameters enveloped in the geartooth flank generating, the complicated double parameter envelope is simplified to the generating process between work-piece and imaginary crown generating gear by means of mathematical transformation . the equation of the imaginary crown generating surface and the partial derivatives are deduced, so the differential geometric parameters of the generating surface can be obtained . by analyzing the generating motion between the imaginary crown generating gear and the work-piece, all the first to third order geometric parameters of the generated tooth flank at any given point can be calculated
   文摘:為了解決直接求解展成法加工中存在的復(fù)雜雙參數(shù)包絡(luò)問題時的困難，提出通過數(shù)學(xué)變換，將此包絡(luò)問題轉(zhuǎn)化為假想平面產(chǎn)形輪與工件之間的展成問題來進行研究.推導(dǎo)了假想產(chǎn)形面的方程和各階偏導(dǎo)矢，于是可獲得產(chǎn)形面的微分幾何參數(shù).通過分析假想平面產(chǎn)形輪與工件之間的展成運動，即可得到被展成齒面上任意指定點的全部一至三階微分幾何參數(shù)
