On Popularization of Theory of Heat among Engineers and its Application to the Steam Engine in the 19th Century

我把注意力集中在戴维斯吉尔伯特身上，他是康沃尔语工程师和科学家中的核心人物。吉尔伯特肯定支持热素理论。虽然戴维、拉姆福德伯爵和赫拉帕斯都主张热的动力学理论，但这一理论在当时并没有应用到尖端的蒸汽机上。根据以前的一些研究，吉尔伯特很可能是工程师和科学家的赞助人。然而，伍尔芙报告绝热膨胀的高压蒸汽缸吉尔伯特。也就是说，工程师不仅从科学家那里得到指导，而且工程师把科学知识传授给科学家。19世纪30 -40年代，以热理论为基础的“蒸汽机理论“在工程师中流行，一些工程师对“蒸汽机理论”进行了修正，以调整真实的高压蒸汽机。这些引擎和指标都是基于这一修正。

I focused on Davies Gilbert who was a central figure among Cornish engineers and scientists. Gilbert must have supported caloric theory. Although Davy, Count Rumford and Herapath advocated kinetic theory of heat, this theory was not applied to the cutting-edge steam engine at that time. According to some previous study, Gilbert was likely to a patron of engineers and scientists. However Authur Woolf reported adiabatic expansion of high-pressure steam in cylinders to Gilbert. That is to say, engineer did not only get coaching from scientist, but also engineer inform scientist of scientific knowledge. “Theory of the Steam Engine “which was based on caloric theory was popular among engineers in 1830-40’s and “Theory of the Steam Engine” was corrected by some engineers to adjust the real high-pressure steam engine. These engines and indicators were based on this correction.
