intrinsic heat 中文意思是什麼
intrinsic heat
解釋
固有熱-
And the results of calculation and numerical simulation indicate, without increasing the intrinsic collector - junction area of power devices, collector - combed structure helps to raise the intrinsic heat - dissipating area and base ' s perimeter, improve heat - dissipating method of each cell of the chip, enhance the distribution uniformity of junction temperature and current of each cell of the chip, reduce the thermal resistance and raise the dissipation power pd and output power p0, fairly well relax the contradiction among frequency, out - put power and dissipation power of the devices, and further improve the devices " property against second breakdown
而計算分析和二維數值模擬分析結果表明：梳狀集電結（基區）結構在不增加器件本徵集電結面積的條件下，增大了器件的本徵散熱面積和基區周長，改進了每個子器件單元內的散熱方式，提高了單元內結溫和電流分佈的均勻性，降低了器件的熱阻，增大了器件的耗散功率和輸出功率，較好地緩解了目前傳統結構中頻率與功率、功耗的矛盾，並有利於改善器件抗二次擊穿的性能。 -
Because of its excellent properties, such as high strength, high module, wear resisting, and etc., sicp was added to ferroalloy as a reinforce phase. but the intrinsic difference between the bonds led to poor fabrication of the composites. in this paper, the effects of alloying, sintering, and heat - treatment on the properties and microstructures of sicp / ferroalloy - based composites were studied, : it was found that sic particles reacted with ferroalloy when sintered in 1100
碳化硅因其高強度、高模量、耐熱、耐磨等優良性能而被作為顆粒增強體來制備鐵基復合材料，但因其共價鍵與鐵基體的金屬鍵之間的本質區別導致兩者復合困難，本文擬從基體合金化、燒結及熱處理工藝等方面對鐵合金基復合材料組織與性能的影響進行考察，具體內容如下：加入fe - cu - c基體中的sicp顆粒， 1100燒結時就已經開始發生分解，但反應不強烈，在顆粒表面鍍鎳可以延緩基顆粒與基體之間的反應。
