Unique a 3 segments ' temperature curve program achieves a steady heat rising and good protection of bga component 獨(dú)設(shè)一組三段式溫度曲線編程,分三個(gè)階段升溫,實(shí)現(xiàn)穩(wěn)定的升溫效果,讓bga組件得到妥貼的保護(hù)。
At the same time , the conductivity factor and the entropy of phase change of the solidation fatty alcohol were measured separately by using the time - temperature curve and dsc 同時(shí)利用時(shí)間-溫度曲線法和dsc測(cè)定了固化十二醇的導(dǎo)熱系數(shù)與相變焓。
In this thesis , behaviors of unbonded prestressed concrete slabs including 4 simply - supported slabs and 9 continuous slabs are investigated under fire , based on the elevated temperature curve accord to the iso standard fire curve 本文采用標(biāo)準(zhǔn)升溫曲線,對(duì)4塊簡(jiǎn)支板及9塊連續(xù)板分別進(jìn)行了火災(zāi)行為的試驗(yàn)研究。
The resistivity - temperature curve can be predicted by using this mathematical model , which was in good agreement with the experimental data when the cb volume fraction is close to the critical volume fraction 利用這個(gè)數(shù)學(xué)模型,還對(duì)兩種ptc材料的阻溫曲線進(jìn)行了預(yù)測(cè),與實(shí)測(cè)結(jié)果比較發(fā)現(xiàn),當(dāng)炭黑含量在滲流閾值附近時(shí),預(yù)測(cè)值與實(shí)測(cè)數(shù)據(jù)吻合很好。
A viscosity - temperature model of cumulative steam injection rate and cumulative oil production has been established for cyclic steam stimulation stage according to the standard viscosity - temperature curve of american material experiment society 摘要根據(jù)美國(guó)材料試驗(yàn)學(xué)會(huì)制定的標(biāo)準(zhǔn)粘溫關(guān)系曲線,建立蒸汽吞吐階段累計(jì)注汽量與累計(jì)產(chǎn)油量之間的粘溫模型。
The resistance of sample l # ( 44nm ) and sample 2 # ( 50nm ) rises rapidly from 25k and 45k respectively , and an inflexion appears at the temperature in the resistance - temperature curves . the same inflexion appears at 75k in the resistance - temperature curves 晶粒尺寸為44nm和50nm的1 #和2 #樣品的電阻率分別在25k和45k附近開(kāi)始隨溫度的升高快速增大,在曲線上出現(xiàn)拐點(diǎn)。
Iv ) for the strong interfacial coupling , there exist three pyroelectric peaks in the temperature curve of pyroelectric coefficient , and with the decrease of the interfacial coupling , the number of the pyroelectric peaks will decrease gradually 我們還發(fā)現(xiàn),較強(qiáng)的界面耦合導(dǎo)致熱電系數(shù)的溫度曲線上的三個(gè)熱電峰的出現(xiàn);而界面耦合強(qiáng)度的減弱及鐵電超晶格尺寸的減少將導(dǎo)致某些熱電峰的消失。
