From 500℃ to 550℃, the oxide scale presents a relatively compact morphology, the oxidational wear is the principal wear mechanism and the wear rate is very slow at 500℃ owing to the anti-friction effect of the oxide scale.

本文研究了5CrNiMo在400℃、500℃、550℃及600℃温度下的滑动磨损行为，利用扫描电镜，波谱仪及X射线衍射仪对磨损面形貌及成分进行了分析，结果表明：5CrNiMo钢磨损机制随温度的变化而变化，400℃时表现为疲劳剥落和磨粒磨损，500℃至550℃时表现为氧化磨损，600℃时主要是粘着磨损。

In the initial stage of the bioleaching, when the bacteria are not active, the chemical oxidation of ferric irons to the solid sulfide minerals is primary; While in the whole course of the bioleaching, it is very limited; ferric irons inhibit the bacterial activity, lower the oxidational ability of the bacteria to ferrous irons in the liquid phase; ferric irons and their precipitations reduce the quantities of the attached bacteria and their activity, and have bad influence on the direct bioleaching action.

结果表明，在浸出的初始阶段，Fe3+的化学氧化作用是主要的；但在整个金属浸出过程中，Fe3+的化学氧化作用是很有限的；Fe3+对T.f菌有一定的抑制作用，降低了它们对液相中Fe2+的氧化能力；Fe3+及其沉淀使细菌在固体矿物颗粒表面的吸附量减少，降低了吸附细菌的活性，从而影响了细菌的直接氧化浸出作用。

A new catalytic spectrophotometry was established for the determination of trace silver based on the catalytic effect of Ag on the oxidational discoloration reaction of methyl violet with potassium persulfate in buffer medium of HAc-NaAc including phenothroline as activator.

Under condition of different temperature and sulphur consumption, the brown coal and gypsum can promote oxidation of sulphur,the oxidational rate of sulphul is the highest under the condition of applying brown coal and gypsum;The sulphur is oxidized for SO42~ the oxidational rate of sulphur during 0-15 days' incubtation was the highest on the whole,reach the maximum basically within 30 days,up to the extension of time,SO42"""" the content is reduced to some extent;Final SO42 -content, Ig sulphur / kg treatment of soil greater than 0.5g sulphu/kg treatment of soil,become multiple increase,the sulphur is higher than the room temperature in the efficiency of oxidizing of 30 degrees Centigrade (10-20 degrees Centigrade).

在不同温度和硫磺用量的条件下，褐煤与石膏对硫磺的氧化有促进作用，其中褐煤与石膏配合施用对硫磺氧化的促进作用最大；在硫磺氧化为SO_4~(2-)的过程中，0-15天内氧化速率最大，30天内基本达到最大值，随时间的延长，SO_4~(2-)含量有所降低；硫磺在30℃的氧化效率高于室温(10-20℃)，在1克硫磺的处理中，30℃时最大SO_4~(2-)的含量是室温(10-20℃)的1.24倍，在0.5克的处理中有同样的规律，30℃时SO_4~(2-)的含量是室温的1.6倍。
