| 高溫高壓條件下熱學性質(zhì)研究的意義卻是毋庸置疑,高溫高壓條件下原位熱學性質(zhì)研究對于完善熱物性數(shù)據(jù);研究新(熱電)材料;探索地球物理中地球動力學、地質(zhì)演化學和地球內(nèi)部物質(zhì)的結(jié)構(gòu);探究材料高溫高壓條件下的結(jié)構(gòu)相變等都有重要的意義。最早的礦物高壓熱導率測量實驗的方法是穩(wěn)態(tài)徑向熱流法,或則稱為同心圓柱法,是 Bridgman(1924)引入高壓實驗的,樣品被制作成中空的圓柱形。圓柱中心放置線性熱源,圓柱樣品外包裹散熱材料。給熱源加載恒功率電流,使其產(chǎn)生穩(wěn)定熱流,最終在徑向產(chǎn)生穩(wěn)定的溫度場。在圓柱樣品的內(nèi)表面和外表面布置熱電偶,測量兩界面的溫度差。根據(jù)溫差和加熱功率,以及由傅里葉定律推導出的圓柱體內(nèi)徑向一維熱流的傳導方程,就可以計算出樣品的熱導率。這種方法存在較大的熱阻,而且所使用的塑性傳壓介質(zhì)在高壓下的塑性流動又會造成兩熱電偶間距的不確定。 |

The significance of studying thermal properties under high temperature condition is no doubt. There are great significances on in situ thermal properties research for improving thermal physical properties under high pressure condition; studies of novel (thermoelectric) materials; explorations of the structure of geodynamics, geological evolution and earth interior material In Geophysics, as well as Structural transformation of materials under high temperature and high pressure,.etc. The earliest experimental method for measuring mineral high thermal conductivity is steady state radial heat flow method, which is also known as concentric cylinder method introduced by Bridgman(1924). The sample was made into a hollow cylinder. Linear heat source was placed in the center of cylinder, and Heat dissipation materials were wrapped outside the cylinder sample. Loading constant power current to heat source could produce stable heat flow and ultimately have stable temperature field. Thermocouple on the inner and outer surface of the sample is arranged to measure the temeprature differrences of the two interfaces. According to the temeprature differrence and heating power, as well as the cylinder diameter to one-dimentional heat flow conduction equation derived by Fourier law, the sample’s thermal conductivity can be calculated. This method has a larger thermal resistance, and plastic flow of the plastic pressure transmission medium under high pressure will lead to uncertainty of the two thermocouple spacing. --- 只能僅供參考,像術(shù)語的表達和意思就只能樓主自行斟酌了。 |
