exothermal 中文意思是什麼
exothermal
解釋
放熱的；生熱的-
The most important exothermal reactions in the crust can be expected from the chemical transformations of sulfides.
地殼中能夠料想到的最重要的放熱化學反應是硫化物的化學轉變。 -
At the some time, the reaction between ti and al also is an exothermal reaction, so the inner energy is increased sharply which prompt al3ti to decompose and the diffusion rate of ti toward graphite particles and the decrease the inoculation tune
同時加鎂後生成的tic顆粒的擴散速率增大，因而增大了tic顆粒的形核數，使生成的tic顆粒更加細小彌散，在復合材料中的所佔體積分數增大。 -
Before 900 c, ti reacts with al to form tial intermetallics ; above 900 c, c reacts with remain ti to form tic triggered by the exothermal reaction of ti and al ; tial reacts with tic to produce dense tial / ti2alc composites
間的放熱反應引發c和未反應完全的ti反應生成tic ; tiai金屬間化合物和tic反應併合成緻密tiai / tizaic復合材料。通過保溫階段， tizaic長成層狀多品結構，同時復合材料緻密化。 -
Abstract : the preparation conditions of unsaturated polyester ( up ) resins modified by pet were introduced in this paper. the copolymerization mechanisms of the synthesis of up resins from cis - and trans - anhydride were researched. the relationship between the modified resins activities and the structure of unsaturated acids were also discussed. the reason for the differences of the exothermal curves of the two resin systems was that the activity of the cis - and trans - unsaturated bonds was different from each other
文摘:本文研究了由聚酯改性合成不飽和聚酯樹脂的反應機理和工藝條件，討論了改性樹脂反應活性與不飽和酸結構之間的關系，解釋了順、反式雙鍵結構對改性樹脂固化放熱特性和反應活性不同的原因。
