external heat source
解釋
外來的熱源-
Based on the detection principle of pyroelectric sensing elements, this paper presents a symmetrical peak detection method of continuous double plus - minus pulse signals to eliminate external interference in fixed position heat source
根據熱釋電敏感元件的探測原理,本文提出一種對正負脈沖信號和連續正負脈沖信號進行對稱峰值檢測的方法。 -
In the external region, heat transfer between the u - tube borehole and the ground is considered with a model of a finite line - source in a semi - infinite medium, and it is the first time to achieve an analytical solution of the temperature distribution for a such a transient two - dimensional conduction problem by means of the green - function method
對單個鉆孔的傳熱劃分為兩個區域分別進行研究。在鉆孔周圍區域,將豎直u型管的傳熱簡化為有限長線熱源的傳熱問題,採用格林函數法首次得到了有限長線熱源溫度分佈的解析解。
