A noninvasive method of measuring the blood flow rate in the cutaneous tissue by the thermal diffusion between the skin and a metal is described. 介紹了一種利用人體皮膚和接觸導體的熱傳遞來(lái)無(wú)創(chuàng )測量局部皮膚組織中血液流速的方法。
The improvement in thermal efficiency for a simple Rankine cycle is by virtue of the bled-steam releasing all of its heat to the feed-water, and little or none to the condenser. 一個(gè)簡(jiǎn)單的朗肯循環(huán)熱效率的提高是憑借蒸汽釋放所有熱給給水，并且很少或沒(méi)有熱傳遞給凝汽器。
This kind of material is perfect for making heating radiators because of its fast transmission of heat. 這種材料傳熱很快，適合做暖氣片。
The effective thermal resistance and the effective coefficient of heat transfer during the formation of fouling are defined. 提出了污垢形成過(guò)程有效熱阻與有效總傳熱系數的概念。
