Through analyzing the experimental data,the quantitative dependence of resistance varying-ratio on cutting-length varying-ratio of transverse-cutting is gotten,and the function of them when cutting-length varying-ratio is less than 55% is fitted.
通過(guò)實(shí)驗(yàn)數(shù)據(jù)分析得出激光橫向切割的長(zhǎng)度變化率與阻值變化率之間的定量結(jié)論 ,并擬合了有效橫向切割長(zhǎng)度的阻值變化率與切割長(zhǎng)度變化率之間的關(guān)系函數(shù) ,二者能夠?yàn)樘岣哒{(diào)阻精度和調(diào)阻效率提供控制依據(jù)。
Based on analysis of the causes,method for reducing heated length variation as well as simplified identifying approach are proposed aiming at its technological process.
加熱長(zhǎng)度變化率是國(guó)家標(biāo)準(zhǔn)規(guī)定的塑料地板磚的物理性能指標(biāo)之一,目前不少產(chǎn)品此項(xiàng)指標(biāo)未能達(dá)到國(guó)家標(biāo)準(zhǔn)。
