For example, H, atomic weight of 100,794 hydrogen, carbon FC atomic weight of 1201, the atomic weight of oxygen O for 1594, Copper Cu for F63546 and so on. F history, had also used the other two kinds of "benchmarks", and there have been two kinds of scales used in parallel .1803 years, J Dalton published the first atomic table, the hydrogen-quality of the original F son as a "benchmark "requiring H, atomic weight is 1. In 1826, JJ Berzelius Tony F are presented to the quality of 116 oxygen atoms O as a" baseline "(scheduled for O, E atomic weight 16), which is has been in use to 1961 "Oxygen unit." 1929, found that the oxygen in nature, in addition to the greatest abundance of 16O, there are a small amount of slightly heavier 17O and 18O two kinds of isotopes, and the different sources of oxygen, its composition is slightly different.
例如氢H的原子量为100794,碳FC的原子量为1201,氧O的原子量为1594,铜Cu为F63546等。F历史上,还曾用过另外两种"基准",并且有过两种标度并行使用。1803年,J道尔顿发表的第一张原子量表,把氢原F子的质量作为"基准",规定H的原子量为1.1826年,JJ贝F采利乌斯提出,以氧原子O质量的116作为"基准"(定O的E原子量为16),这就是一直沿用到1961年的"氧单位"。1929年发现,自然界中的氧,除丰度最大的16O以外,还有少量稍重的17O和18O两种同位素,并且不同来源的氧,其组成也稍有不同。

At last, we has indeed confirmed the increase of oxygen contained on the sample's surface relative to background concentration in the bulk by the measurement of ESCA as well.

The results show that the perfect strength can be obtained under oxygen partial pressure about 20% O2, overhigh or low oxygen partial pressure is unfavorable for recrystallization of Fe2O3, which causes a decrease of pellet strength. The original hematite will be transformed into magnetite on reduction firstly when carbon-burdened hematite pellet is roasted in oxidizing atmosphere, and then the magnetite will be oxidized to secondary hematite, which is more active than original hematite, therefore, the induration strength of pellet is able to be enhanced.
研究结果表明:内配碳赤铁矿氧化球团在接近空气配比(氧含量约20%,体积分数)的氧化性气氛中焙烧强度最大,氧含量过高或过低都会影响Fe2O3的再结晶,使球团强度降低;在氧化性气氛中焙烧含碳赤铁矿球团时,原生赤铁矿先还原为磁铁矿,磁铁矿再氧化成活性较高的次生赤铁矿,提高了赤铁矿焙烧固结性能和球团强度。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.
StreeterPhelps模型是目前进行河流水质研究常用的物理模型,具有良好的理论和实用价值,然而在某些特定水域,该模型的应用受到限制,主要原因是复氧系数的取定多在水流速度较大情况下得到的,而未考虑水面波动对复氧系数的影响,另外,在实际研究过程中发现三峡库区COD变化的规律出现异常:在离排污口相当远的水域,COD随时间变化趋势并不是指数衰减,而是在某个常值附近微小摆动,以往很多修正过的StreeterPhelps模型都无法解释这个现象。

The paper studied the scavenging active oxygen radicals of brown pigment from chestnut shell. The results showed that the brown pigment had scavenging effects on hydroxyl radical, superoxide anion radical and aliphatic radicals on lipid-peroxidation. In the range of test concentration, the maximum scavenging or inhibition rate of the brown pigment to hydroxyl radical generated by Fenton reaction, superoxide anion radical generated by illuminating riboflavin system and linoleic acid auto-oxidation was 83.0%, 82.1% and 88.5% respectively.
