In this paper, the Iron-oxide-coated sand absorption character prepared in different temperatures was studied, mainly tested its absorb hexad chromium, and the inherent reason that formed this differences was explained.

本文研究了不同温度下制备的铁覆膜砂吸附性能的差异，对铁覆膜砂吸附Cr的性能进行了综合的测试，说明了形成这些差异的内在原因制备温度对IOCS的吸附性能有显著影响，一般低温制备的IOCS要比高温制备的铁覆膜砂吸附性容量较大，去除效率较高；覆盖在石英砂表面的铁氧化物在不同的焙烧温度下形成了不同的物质，110℃的低温一般形成FeOOH，而600℃高温下形成的则为α-Fe2O3。

These methanols were treated with BF3 in CH2Cl2 to generate the diferrocenylmethyl carbocations. Without separation from the reaction mixture, the ions were treated with some amines RNH2 [R=C2H5, n-C3H7, n-C4H9, HOCH2CH2, HOCH(CH3)CH2, HOCH2CH(C2H5)] to afford the ferrocenylamines in high yields. The present methodology for preparing α-ferrocenylamines from α-ferrocenyl alcohols enjoys such advantages as simple procedure and inexpensive starting materials.

它们对酸的敏感性很高，与BF3在二氯甲烷中作用可形成稳定的二茂铁基甲基碳正离子，无需从溶液中分离出来，便可与胺RNH2[R=C2H5，n-C3H7，n-C4H9，HOCH2CH2，HOCH(CH3)CH2，HOCH2CH(C2H5)]作用得到产率颇高的二茂铁基胺，这种由α-二茂铁基醇制备α-二茂铁基胺的方法具有简单、快速和原料廉价的特点。

The experiment study about the subcritical normalizing holding temperature effects the macrostructure and hardness of the 40SiMnCrNiMoA steel shows: When subcritical normalizing holding temperature is 760℃, the ferrite in the mixture phase structure is lumpish, the hardness of the steel is low (about HRC32), and when the holding temperature is over 800℃, the hardness of the steel is about HRC49, the ferrite in the mixture phase structure is in old critical range austenite grain boundaries, it is disadvantage for the steel strengthening. When the holding temperature is 780℃, the mixture phase structure is mixture phase structure including the strip ferrite、martensite and bainite, the ferrite is less than 20%wt, its grains are fine and even, the hardness of the steel is about HRC38, it is in the range of HRC35-40 which is the long-life drill rod needed.
