Compared with pure pmma, the thermal and mechanical properties of the nanocomposites are obviously improved at a very small amount of mmt ( ommt ) loading. the tgs of the composites via different methods are improved by 10 ~ 26 ?, the decomposition temperatures at weight loss of 5wt % are increased by 42 ~ 99 ?. in the bulk system, tensile strength, tensile modulus and impact strength are improved by 32. 2 %, 60. 3 % and 68. 6 %, respectively, without the loss of light transmittance
相對于純pmma體系，懸浮法、乳液法及本體法復合材料的t _ g值提高了10 26 ；后兩種復合材料熱失重5wt的溫度提高了42 99 ；而本體法復合材料的拉伸強度、拉伸模量及沖擊強度值最大分別提高了32 . 2 、 60 . 3和68 . 6 ，而透光性能基本未受影響。 -
The results demonstrate that the theory predicted values of compression, bulk modulus, linear expansion, and thermal expansive coefficient of compressed solids are very agreement with the corresponding experimental data. in summary, the error with respect to theory prediction and its causes are pro bably analyzed in detail. the discussion suggests that the function of the phenomenological short - distance repulsive force constant a ( v ) and approximation for anderson - griineisen parameter 5t ( v ) proposed in this paper are valid and applicable in high pressures ( up to loogpa ) and high temperatures ( from debye temperature 0d to melting temperature tm ) for many types of solids
在本文最後一節，為了驗證固體在等壓過程中anderson grhneisen參量乓與體積膨脹的唯象假設：乓久w兀的有效性，及由此假設而推導出來的等壓態方程的廣泛應用性，本論文主要針對十六種堿金屬鹵化物、三種堿性氧化物、三種硅酸鹽礦物質的線膨脹八n 、體積熱膨脹v vo （ n 、熱膨脹系數a （ n 、體積彈性模量肘d等隨溫度的變化作了理論上的預測，且與相應的實驗數據作了比較與分析 -
By the measurement of xrd, sem, shrinkage and bulk density of glass ceramics, the effect of crystallization temperatures on performances of nb - ta tailing glass ceramic treated at various temperatures are investigated
摘要通過xrd 、 sem和收縮率、體密度的測定，研究在熱處理中晶化溫度對鈮鉭尾礦微晶玻璃顯微結構和性能的影響。 -
The experimental results of the condensation coefficient obtained from the liquid and vapor temperatures near the interface and the results from md simulations are in the same order, but those obtained from the bulk liquid and bulk vapor temperatures are four to five orders lower than the results from md simulations
採用準穩態方法對水的蒸發過程進行了實驗研究。研究表明，使用界面溫度獲得的蒸發系數實驗結果與分子模擬獲得的凝結系數差距不大，但採用主流區溫度獲得的蒸發系數與模擬計算結果相差可達4 ~ 5個量級。 -
When surface temperatures of uranium and uranium - niobium alloys increase higher than 573k, heating was observed to deplete surface oxygen by accelerating its transport into the bulk and separate carbon out to their surface. so there were uranium carbide formed on the surface and thicker layer of uo _ ( 2 ) formed in the bulk. with surface temperature increasing, the o / u ratio dropped sharply as the surface oxygen diffused into the bulk
當溫度高於573k時，溫度增強了鈾及其合金表面上的氧的解吸和向體內擴散，以及促使體內的碳向表面上偏析，導致在鈾及其合金表面上形成了鈾碳化合物，並在體內出現富二氧化鈾層，隨著溫度的升高，表面上的氧和鈾原子的比值降低，鈾碳化合物含量增加，體內的富二氧化鈾層加厚。
