( 3 ) based on the kinematical theory of mbs , the calculation methods for the ideal center envelop curve of grinding wheel on cam grinding , the practical cutter track , inverse contour of cam , ideal nc instructions , precision nc instructions , the inner / outer normal and the fitting criterion of curve have been all discussed in detail in this paper
( 3 )通過(guò)精密加工的約束條件方程,探討理想刀具路線、逆變數(shù)控指令與實(shí)際刀具軌跡之間的映射關(guān)系,解決誤差補(bǔ)償技術(shù)提高加工精度的核心問(wèn)題? ?當(dāng)要求數(shù)控磨床的砂輪中心準(zhǔn)確到達(dá)給定的理想點(diǎn)時(shí),精密數(shù)控指令值究竟該是多少,如何能夠通過(guò)計(jì)算,獲得這樣的數(shù)控指令值,給出經(jīng)修正的數(shù)控指令計(jì)算方法。 - The major findings were : ( 1 ) except the chi square test that was easily influenced by the sample size , the results indicated that the english learning process model fitted the observed data well in preliminary , overall , and internal structure model fit criteria . ( 2 ) the direct effects in the english learning process model were significant regarding their affective reaction with action control , affective reaction with metacognition , action control with metacognition , and metacognition with learning performance ; the indirect effects were also significant regarding their affective reaction with metacognition , affective reaction with learning performance , and action control with learning performance
二、國(guó)中生英語(yǔ)學(xué)習(xí)歷程模式中，情意反應(yīng)對(duì)行動(dòng)控制具直接效果；情意反應(yīng)對(duì)后設(shè)認(rèn)知具直接效果；行動(dòng)控制對(duì)后設(shè)認(rèn)知具直接效果；后設(shè)認(rèn)知對(duì)學(xué)習(xí)表現(xiàn)具直接效果；此外，情意反應(yīng)對(duì)后設(shè)認(rèn)知與學(xué)習(xí)表現(xiàn)具間接效果；而行動(dòng)控制對(duì)學(xué)習(xí)表現(xiàn)亦具間接效果。 - In this paper , the working fluid is air . experimental study of the nine different structure parameters of 3 - d ift with staggered arrangement fins in the reynolds number range of 250 to 30000 is performed to investigate the characteristics of heat transfer and flow friction behavior . analyses and reduces the experimental data by the least square method , obtains the nusselt and fanning friction fitting criterion equations
