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。     

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.     

相位差与q变形广义相干叠加态的压缩特性

对于q变形的非简谐振子广义相干态的叠加态β〉+eiφβeiδ〉,其量子涨落的可能高阶压缩阶数可以表示为k≠2πn/δ,这里n是整数.当δ=π时,压缩阶数不能是偶数即只能是奇数,这正是q变形非简谐振子广义奇偶相干态的结果.由此表明参数相位差δ对决定q变形的非简谐振子广义相干态叠加态的高阶压缩阶数起决定性作用.     

Identical Superdeformed Bands in ^171Ta and ^173Re

The rotational band built on the i13/2 proton [660,1/2] Nilsson state in ^173Re is proven to be identical to that in ^171Ta.The close similarity of the two bands in ^171Ta and ^173Re suggests that the ^173Re nucleus with the odd proton based on the i13/2 [660,1/2] Nilsson state may be triaxially superdeformed.

κ玻色子q相干态的反聚束效应

研究了q变形湮没算符高次幂（αq^k,κ≥3)本征态的反聚束效应，并就κ=3的情况用数值计算方法研究了q变形参数对该效应的影响。结果表明，当q变形相干态中谐振子的强度x=|z|^2在某些区间内取值时，αq^k的本征态将呈现反聚束效应，并且这一效应明显地受到q参数的影响。当参数q取定时，随着q变形光场强度的变大，该光场的光子数涨落在经典（或量子）和量子（或经典）特性之间交替地变化。
