adj. 吸熱的
For the process of the isomerizations, the former is endothermal reaction, the later is exothermic.
前者異構化為吸熱反應,後者為放熱反應。
The experimental results indicated that the changes of height and temperature of the small endothermal peak appearing at 310-325k with storing time is relative to the cooling conditions.
實驗表明,在310 ~ 325 K出現的熱焓松弛峰的峰高和峰溫隨存放時間的變化與冷卻條件有關。
When the concentration of benzoic acid was high, the adsorption was an endothermal process with the system's entropy increasing, and the increase of temperature did benefit to the process.
當苯甲酸濃度較高時,吸附為吸熱過程,體系熵增加,升溫有利于吸附。
In order to produce dry sanding paper applied to soft materials, the slurry coating was prepared by smearing unblocked materials according to the phase change principle of endothermal agents.
為研制適用于軟質材料磨削的幹磨砂紙,通過塗覆特殊的防堵塞材料,利用吸熱劑的相轉變原理,研制了幹磨砂紙超塗層漿料。
endothermal(吸熱的)指在過程中吸收熱量的物理或化學變化。該術語與endothermic同義,廣泛應用于熱力學、化學及材料科學領域,描述系統從周圍環境獲取能量的現象。以下是詳細解釋:
endothermal 過程發生時,系統(如化學反應體系或物理變化的物質)需從外部環境吸收熱能,導緻系統自身溫度降低或環境溫度下降。其熱力學判據為焓變(ΔH)為正值(ΔH > 0),即系統能量增加。例如冰融化為水時吸收熱量,屬于典型的吸熱過程 。
吸熱過程中,環境傳遞的熱能轉化為系統内部的勢能或分子動能。例如在蒸發過程中,熱量用于打破液态分子間的氫鍵,增加分子運動自由度,最終以氣态分子動能形式存儲 。此過程遵循能量守恒定律,可用公式表達為:
$$
Delta H{text{system}} = Q{text{absorbed}}
$$
其中 ( Q_{text{absorbed}} ) 為系統吸收的熱量。
endothermal 是形容詞,主要用于描述化學反應或物理過程中吸收熱量的特性。以下是詳細解析:
在化學和熱力學中,endothermal(同義詞:endothermic)表示物質在反應或形成過程中吸收熱量的特性。例如,冰融化時吸收熱量,屬于吸熱過程。
endo-
(内部) + therm
(熱) + -al
(形容詞後綴),字面意為"吸收内部熱量"。如需進一步了解具體化學反應案例,可參考化學教材或權威科學詞典。
