short thermal test 中文意思是什麼
short thermal test
解釋
短時熱試驗-
Furthermore, both current in - situ conductivity test data interpretation methods and gshp design methods are based on models that only consider heat conduction. therefore, the groundwater flow may impact the results of in - situ thermal property of soil, and then the ghe size, and make the short - time economics of gshp comparatively unattractive consequently
此外，由於現場對巖土熱物參數的測試及分析也都僅考慮了熱傳導的影響，這勢必影響現場測試結果的精度，最終又會引起換熱器大小的變化，使土壤源熱泵的經濟性受到挑戰。 -
Changing the grading of sic particles not only affects the strength and pile density, but also modifies the phase compositions and microstructure of the material. with the reducing of sic particles, the strength of the material increases obviously. the nitrification scheme has the greatest influence on phase compositions and microstructure " of si3n4 ( si2on2 ) - sic, after two continuous nitrification reacting peak and short - time high - temperature treating, the best properties can be obtained ; and the residual strength of the composite is much higher after the thermal shock resistance test, which shows that the material possesses excellent thermal shock resistance
本論文較全面地探討促進強度和顯微結構良好的si _ 3n _ 4 （ si _ 2on _ 2 ）結合相的實驗條件，實驗數據顯示：引入適量的燒結助劑能夠促進si _ 3n _ 4 （ si _ 2on _ 2 ）的生成和晶粒的長大，而過量時，其促進作用反而下降；隨著si粉加入量增加，生成的結合相明顯增多，復合材料的性能顯著提高；改變sic顆粒級配不僅影響復合材料的強度與堆積密度，而且對復合材料的物相與顯微結構也有影響，隨著顆粒逐漸細化，材料的強度有較大的提高；對復合材料的強度、物相與顯微結構影響最大的是氮化制度，經過兩個氮化高峰連續的反應和短時間的高溫后處理得到的復合材料性能最好；通過抗熱震性能實驗后復合材料的殘余強度較高，顯示出較好的抗熱震性能。
