Minute amount of sulfur dioxide and impurities are always present in the air of industrial area. Under sunlight, smog is formed, scattering light and reducing visibility. This article is to ascertain the effect of rate of photochemical oxidation of sulfur dioxide in air at high relative humidities.

工业区大气中常含微量二氧化硫及各种杂质。天晴时可能形成烟雾,分散光线,减缩视距,本研究即系确定其影响。 实验时以经过特种过滤器所得纯粹空气与二氧化硫在不同湿度下混合,贮於Lucite容器(7.94升),用RS日光灯自顶部相继透过红外线过滤器及Plexiglas IA照耀达1至2小时。光切断后作用即中断。所得硫酸气溶胶质点大小作对数一概率分布。然后将硫酸气溶胶在声速下抽经喷射撞击器,利用气溶胶质点惰性作用,收集微量硫酸。撞击器中有百里香蓝处理过的胶片。藉可见光线透过胶片的强度,可以分析硫酸气溶胶的数量,最低可测至0.01微克硫酸。 实验结果显示二氧化硫在高湿度(98%相对湿度)时所得光化学反应速率与低湿度时相同。这表示化学反应主要为气相反应,在液相中反应速率相对而言是很低的。二氧化氮,氯化钠核及五氧化二钒为工业区大气中常存在的杂质,经引入后,并未发生触媒作用。世界上若干工业区大气中二氧化硫在所研究情况下约需300小时中午日光照耀,可将视距减至1公里。

1. Some theoretical considerations about the controversy between Charlesby's and Tang's theories concerning the solubility of crosslinked polymer induced by irradiation are given. Based on Charlesby's definition of the sol fraction, calculations were carried out for the polymer with initial molecular weight distribution (MWD) of the Flory type by method of direct summation; when q→0, Charlesby's formula of solubility was obtained:S=1/(1 + γ - γS)2;and for the polymer with initial MWD of the Schulz type:S= 1/(1+γ/α-γS/α)1+α...

1. Some theoretical considerations about the controversy between Charlesby's and Tang's theories concerning the solubility of crosslinked polymer induced by irradiation are given. Based on Charlesby's definition of the sol fraction, calculations were carried out for the polymer with initial molecular weight distribution (MWD) of the Flory type by method of direct summation; when q→0, Charlesby's formula of solubility was obtained:S=1/(1 + γ - γS)2;and for the polymer with initial MWD of the Schulz type:S= 1/(1+γ/α-γS/α)1+α γS→1=α/1+α2. We introduced fo,ur parameters concerning the internal structure of crosslinked polymer, namely;q (s) no. of crosslinked units in sol q(s) =no.of crosslinked units in sol/no. of total units,p (s) = no. of molecules in sol/no. or total units,γ(s) = q(s)/p(s), γ(g) = q-q(s)/p-p(s).where q is the crosslinking density, and p, the fracture density.Due to the fact that the statistical theory of random crosslinking induced by radiation is really a continuation of the gelation theory of three dimensional polycondensa-tion, the molecular weight of the gel molecule should approach infinity. It is therefore suggested that the necessary condition for formation of gel molecule must beγ(g)≥2; γs→1(g) = 2.Based on the process of gel formation as well as the distribution of crosslinking units and fracture units in sol, we obtained p(s)>pS, and q(s)=qS2

(1)本文认为Charlesby与唐敖庆关于辐射交联高聚物溶解度理论的争论,应先从理论本身进行探讨。我们根据Charlesby溶胶量定义S=sum(nP_(nl)S~l)╱N_0,对Flory型分子量分布高聚物改用加和计算法,当q→0时得到Charlesby关系式 S=1╱(1+γ-γS)~2 此外对Schulz型分子量分布高聚物得到: S=1╱(1+γ╱a-γ╱aS)~(1+a),(?)=a╱1+a(q→0) (2)我们引入了描述高聚物交联体系内部结构及其相互关系的四个参量: q(s)=溶胶中交联单体数╱总单体数,p(s)=溶胶中分子数╱总单体数 γ(s)=q(s)/p(s),γ(g)=q-q(s)/p-p(s)。其中q是交联度,p是裂解度。 按辐射交联统计理论实际上是三向缩聚反应凝胶化理论的继续与发展,凝胶分子的分子量必须为无限大,从而我们提出:形成凝胶分子的必要条件是: γ(g)≥2。 根据凝胶形成过程以及交联单体和裂解单体在溶胶内部分布情况,对溶胶必须满足条件: p(s)>p·S,q(s)=qS~2
