传热系数的简化计算

本交通过传热系数计算式的讨论，得出了传热系数的简化公式，根据B值的大小，定量地给出简化计算应满足的条件，并用实例来验证简化公式的准确性，这种简化计算所产生的误差总是在传热计算的允许误差（＜10％）范围内．     

浅谈生态住宅环境

中国，在第八个五年计划时期，开始提出到2000年将以实现小康水平为战略目标，住宅是小康水平的关键，也是人们议论的热门话题，全社会也已形成“小康不小康，关键看住房”的共识。衡量一个国家的居住水平，国际上采用综合性指标评价，也就是用多个指标来衡量。中国制定的小康居住目标有十三项指标。其中室内环境标准主要考虑室内光环境、热环境、声环境以及卫生环境。     

e-A深度非弹性散射中胶子辐射振幅的新计算方法

在e-A深度非弹性散射过程中, 喷注穿过冷核介质时, 多重散射诱导胶子辐射会导致对碎裂函数的修正及喷注的能量损失.前期研究中关于计算e-A深度非弹性散射中胶子辐射振幅的两种方法: 螺旋振幅近似和微扰QCD严格计算都异常繁杂. 本文发展了一种新的方法, 可以方便计算出多重散射导致胶子辐射的振幅, 得到的碎裂函数的修正以及能量损失与严格计算的结果一致.     

Thermal Rate Constants of the N（^4S）＋O2（X^3∑g^-） → NO（X^2Ⅱ） ＋O（^3P） Reaction on the ^2A′ Potential Energy Surface

A quasiclassical trajectory study with the sixth-order explicit symplectic algorithm for the N（^4S）＋O2（X^3∑g^-） → NO（X^2Ⅱ） ＋O（^3P） reaction has been reported by employing a new ground potential energy surface. We have discussed the influence of the relative translational energy, the vibrational and rotational levels of O2 molecules on the total reaction cross section. Thermal rate constants at temperatures 300, 600, and 1000 K determined in this work for the reaction are 4.4 × 10^7, 1.8 × 10^10, and 3.1 × 10^11 cm^3mol^-1s^-1, respectively. It is found that they are in better agreement with the experimental data than previous theoretical values.     

Foundation of three—dimensional mathematical models for glass furnace regenerator

This paper presents a practical three-dimensional meathematical model of circulation and heat transfer in generator of glass melting furnaces.The model was based on the heat transfer between the smoke flow and the lattice units,and between the air flow and the lattice units.This model not only bypassed the difficulty of complicated computation of the heat transfer process in the regenerator of glass furnaces,but also avoided the irrationality of fixing the temperature distribution on the surfaces.Use of the model yielded very important data and also the method for the design of the regenerator of glass furnaces in practical production.

Application of Electron-Shelving Detection via 423 nm Transition in Calcium-Beam Optical Frequency Standard

A new scheme of small compact optical frequency standard based on thermal calcium beam with application of 423 nm shelving detection and sharp-angle velocity selection detection is proposed. Combining these presented techniques, we conclude that a small compact optical frequency standard based on thermal calcium beam will outperform the commercial caesium-beam microwave dock, like the 5071 Cs clock （from Hp to Agilent, now Symmetricom company）, both in accuracy and stability.
