  caloric theory
For Rumford heat and cold radiation consisted in sound-like undulations in the ether, a mechanism compatible with his own vibration theory of heat, and discordant with the caloric theory.
      
Rumford's strong arguments were overruled only because of the general dominance of the caloric theory of heat.
      
However, Rumford did push the caloric theory to develop in a direction that eventually led to its downfall.
      
Students in this study had been exposed to the kinetic theory in the previous semester and yet some of them had no problem in consistently using the caloric theory, while others switched between the two conceptualizations.
      
It is concluded that an epistemological belief in the caloric theory of heat forms part of the hard-core of students' framework and that the conceptual shift to the kinetic theory requires radical restructuring (Chinn >amp;amp; Brewer, 1993).
      
  thermal theory
The most elaborated ideas are the thermal theory and the theory of the local charging of cavitation bubbles, wherein the latter theory provides the best fit to experimental data.
      
Thermal theory of flame propagation in a condensed medium
      
Thermal theory of hydrodynamic lubrication in hydraulic extrusion in the presence of high-intensity longitudinal ultrasonic vibr

In this paper, appling the selective intermolecular force, the authors have resolved satisfactorily the problems about the solubilities and the beat of solution of polymer, which could not be explained by Hildebrand's theory. It has been shown that the selective intermolecular force is one of the principle causes of the unknown specific interaction between solvent and polymer, described by Dwyer and Karim as well as other investigators, it is considered by authors that the extensive investigations of the selective...

本文以选择性分子间引力论述了高分子的溶解、溶解热等问题,阐述了Hildebrand等建立的混合热理论所未能预测的一些事实;同时讨论了Dwyer等所提出的溶质和溶剂间的特殊相互作用力,认为高分子和溶剂间的选择性分子间引力是特殊相互作用力的重要内容。因为用选择性分子间引力,可以深入理解高分子和溶剂间的选择性本质,所以它对高分子溶液性质的研究是有意义的。

The gears operating at high speed and heavy load have to endure more heat and higher temperatures. Gear temperatures have an effect on the properties of lubricants, the scuffing on gear surfaces and the heat deformation of gears. Therefore, predicting the bulk temperatures in gear teeth is very important. The temperature distribution in spur gears operating in a state of thermal equilibrium can be calculated using a finite element method. With the help of proper suppositions the calculating process may be simplified....

The gears operating at high speed and heavy load have to endure more heat and higher temperatures. Gear temperatures have an effect on the properties of lubricants, the scuffing on gear surfaces and the heat deformation of gears. Therefore, predicting the bulk temperatures in gear teeth is very important. The temperature distribution in spur gears operating in a state of thermal equilibrium can be calculated using a finite element method. With the help of proper suppositions the calculating process may be simplified. The bulk temperatures in gear teeth can be predicted once the heat transfer coefficients and frictional heat input are estimated. A brief introduction to the methods of estimating heat transfer coefficients and frictional heat imput are also presented. In this paper, the temperature of a pair meshing gears has been calculated as an illustration of how the bulk temperature in spur gears is predicted.

在高速重载下工作的齿轮,一般都承受较高的热负荷,故温度较高。而齿轮的温度决定着它是否会发生胶合损坏,决定着润滑剂的特性,同时也决定着齿轮的热变形,故齿轮的温度估算显得十分重要。对于在稳定负荷下运转并处于热平衡状态的直齿轮,可利用有限元法求解其体积温度,并可通过一些适当的假设使问题得到简化,在估算出齿轮的放热系数和输入摩擦热后,便可进行计算。文中还对放热系数和输入摩擦热的理论计算作了一些介绍,并通过对一典型齿轮传动的温度计算,初步探讨了求解直齿轮体积温度的若干问题。

The experimental reseach has been carried out on the ignition improvement by oxygen addition in a small pilot combustion chamber taken from an existing aero-engine. Both uniform mixture method and local oxygen injection method have been investigated. The results show that oxygen addition improves Low pressure ignition performance significantly. Local oxygen injection makes much better use of oxygen added. Experimental results show low evaporation persentage of fuel spray responsible for the poor ignition performance. Based on thermal ignition theory, a semi-analytical equation has been obtained to predict the relative enlargement of maximum ignition velocity by oxygen addition, the equation can correlate experimental data very well. To form a stagnant region with suitable oxygen concentration is the most important factor in the design of ignitor with oxygen additon.

在取自现有航空发动机燃烧室的点火预燃室上,试验研究了加氧对点火的改进。两种加氧方式一均匀加氧和局部加氧,都进行了研究。结果表明,加氧显著地改善了低压下的点火性能。局部加氧更好地发挥了加氧的作用。试验表明,燃油液雾蒸发百分数过低是造成点火性能差的原因。基于点火的热理论,导出了一个半经验半分析的方程,可以预计加氧对最大点火气流速度的相对增大。这方程可以很好地概括试验数据。形成一个具有适当氧浓度的滞止区是设计具有加氧的点火系统的最重要的考虑。
