PERFORMANCE CHARACTERISTICS OF NOx REMOVAL BY AQUEOUS EMULSIONS OF YELLOW PHOSPHORUS

The absorption oflean NO_x (200?1000 ppm) gases in aqueous /% emulsions was investigated in a mechanically stirred vessel. The chemical reaction rate between NO, and P₄ in an alkaline solution was shown zero order with respect to NO_x concentration and three-seconds order to P₄ concentration. In the presence of S0_x=2, the chemical reaction rate between NO_x, and P₄ in alkaline solution was again zero order with respect to NO_x concentration, but changed to second order to P₄ concentration.

In addition, a robust design method was also used to evaluate the relative importance of various processing variables on the performance of this deNO_x process by P₄$ solution. S/N analysis of the results indicated that the P₄ concentration, liquor temperature and NO_x, concentration were the major factors in affecting NO_x absorption efficiencies.     

A note on constant weight cyclic codes

In this paper we show that the dual code of a g-ary Hamming single error-correcting code is a constant weight cyclic code with weight q(m-1). We give, as a consequence, a very simple alternative derivation of the weight enumerator formula for the q-ary Hamming single error-correcting code. We show also that a binary cyclic equidistant code can be derived from this dual code

A note on the arrangement of strain gauges and the sensitivity of strain measurement

A discussion for investigating the yield surface of metal is described. The paper also presents the discussions of the accuracy of strain measurements and the arrangement of three–element 45° strain gauges on a thin–walled tube under combined loadings.     

台湾当代建筑发展论坛

在讨论当代台湾建筑和建筑师时,必然会涉及台湾的历史和文化的发展.台湾建筑受地缘政治和历史的影响十分明显,地理条件独特,政治风云的变幻对台湾的建筑产生了根本性的影响.可以说,当代台湾建筑是人文精神与政治因素、商业化冲撞及平衡的产物.     

NATURE OF ISOTHERMAL TRANSFORMATION BETWEEN ROOM TEMPERATURE AND MARTENSITE POINT IN A BALL-BEARING STEEL

用电阻法研究了含1.43%Cr,1.02%C的滚珠钢在室温到马氏体点(159℃)温度范围内奥氏体等温转变过程。结果指出在这一温度范围内的等温转变是以马氏体转变的形式进行的,而不产生中温转变形式的等温转变。当样品由1100℃淬火至室温后再“上淬”至低于马氏体点的温度进行等温保持时,部分的残留奥氏体即等温转变为马氏体。根据动力学的考虑,这一转变很可能不是通过形成新的晶核,而是已有马氏体晶体的长大过程。同时,这种转变主要受已有马氏体回火过程的控制。在100℃左右长期等温保持时可以得到最大的残留奥氏体转变量。更高或更低的温度,在同一时间内转变量都较100℃左右为小,这可作为精密量具刃具实际热处理的参考。
