From the measured mass, the volume can be determined with a knowledge of water density and corrections for air buoyancy and thermal expansion of the vessel. the volumetric method requires a standard ( calibrated ) volumetric measure
重量分析測定法測定一個測試量器所載或所出的水的質量。從量得的質量，加上水的密度，空氣浮力及容器的熱力膨脹修正，便可測定容量。 -
A dilution of the cb volume fraction due to the thermal volumen expansion of the composites is estimated. if the cb volume fraction decrease to the percolation threshold, ptc effect of the composites occur
隨著聚合物基體的熱膨脹，無論是結晶聚合物基體或非晶聚合物基體體系，只要導電填料的體積分數被稀釋到臨界體積分數以下，復合材料就會產生ptc效應。 -
The group ' s calculated sea - level change is due mainly to thermal expansion of ocean water, with little change in ice - sheet volume
他們的估計主要是根據海水的熱膨脹來估算海平面的改變，而非根據冰原體積的改變。 -
By using this model, the contribution of the thermal volume expansion of the matrix to the ptc transition of the composite is quantitatively estimated. the theory and experiment revealed that the conductive mechanism of abrupt resistivity increase at ptc transition region was equivalent as abrupt resistivity increase at the percolation curve close the critical volume fraction
可以利用這個模型，對基體體積膨脹對ptc轉變的貢獻進行了定量分析，表明ptc轉變區的電阻突變與滲流曲線在臨界體積分數附近的電阻率突變在導電機制上是相同的。 -
The mechanism of physical damage of carbon fibers was clarified firstly. the precursor which attached on carbon fibers changes to inorganic ceramic under high temperature with large volume shrinkage which appearing at cracks with fiber traction and the cracks are mainly vertical to fiber axis. because of mismatched coefficients of thermal expansion, carbon fibers suffer multiple thermal stresses and are damaged
首次探明了碳纖維熱應力物理損傷機制，即碳纖維表面附著的先驅體在高溫下無機化形成陶瓷體，同時伴隨著大的體積收縮，在碳纖維的牽引下，基體的體積收縮以開裂形式出現，裂紋的取向以垂直於纖維軸向為主，由於碳纖維與基體熱膨脹系數失配，致使碳纖維在降溫過程中受到復雜熱應力，引起碳纖維損傷。 -
