Adding N, P could improve cucumber root activity, increased the absorptionof N, P and Mg, decreased that of K; Adding N improved the contents of Ca,Fe, Mn and Zn in leaves, and adding P accelerated absorption of cucumberroot to Fe. Adding K decreased the contents of N, P in leaves, but increased K,Fe content, contents of Ca, Mn and Zn decreased at the same time.4. Adding the rates and ratio of N, P, and K increased the activity of SOD incucumber leaves and root. The changes of POD activity were complex, maybeP played the more important role.

增加氮、磷的用量和配比有利于增强黄瓜的根系活力，促进黄瓜对氮、磷的吸收，减少对钾素的吸收，提高叶片镁含量，增氮提高了叶片中钙、铁、锰和锌的含量；增磷促进了植株对铁的吸收；增钾降低叶片中氮、磷含量，增加植株对钾的吸收，提高了叶片中铁的含量，但钙、锰和锌的含量降低。4。

Most people who are lack of iron don't konw their are iron deficience.

Inthe last stage of reduction,the iron substrates formed on the surface of Wüstite areporous and permeable to gaseous diffusion.The reduction rate is controlled by thesurface reaction on the Wüstite-iron interface,but the rate of this surface reactionis limited by the velocity of CO formation.

在浮士体还原成金属铁的阶段，所生成的多孔性金属铁并不阻碍气相的扩散；还原的速率由浮士休-金属铁相界面的表面反应所控制，而表面反应的速率则受CO的生长速率所限制。

But ferrous sulfate the by-product of TiO2 cannot be effectively used enough in our country over a long period. In order to solve above questions, the dissertation has done some works as follows:Firstly, the process of purifying by-product of TiO2-ferrous sulfate is studied. The craft and condition of the synthesis of micaceous iron oxide with by-product of TiO2-ferrous sulfate was studied through experiments.

它们都可以通过钛白副产硫酸亚铁为原料制备，但是长期以来，我国硫酸法生产钛白的副产物硫酸亚铁得不到充分有效地利用，针对以上情况，本论文主要作了以下几个方面的工作：首先，研究了钛白副产硫酸亚铁的净化工艺路线，讨论了钛白副产硫酸亚铁水热法合成云母氧化铁的工艺路线和条件，讨论了影响云母氧化铁生成的因素，得出了红、棕、灰云母氧化铁合成的控制条件。

Technology of laser hardening surface of diesel locomotive camshaft using austenite-bainite nodular-iron instead of 20Cr has been systematically elaborated on,which includes a series of measurements such as mechanism of choosing austenite-bainite nodular-iron and it's pretreatment,ascertaining laser technological parameter,spiry laser scanning strip,designing four-motor control devise using microcomputer and so on.

阐述用奥贝球铁代替 2 0Cr制造内燃机车凸轮轴的激光表面强化的工艺过程，其中包括奥贝球铁的选择、激光工艺参数的确定、螺旋激光扫描带、四联动微机控制装置的设计等。研究表明，用奥贝球铁代替 2 0Cr制造凸轮轴，经激光表面强化后，能获得更均匀的硬度分布和更高的硬度值。

Effect of sulfurization time, water content, oil as well as sulfur on spontaneous combustion of iron sulfide is investigated on the same sulfide formed from Fe2O3. It indicates that long sulfurization time, some oil, sulfur as well as good ventilation condition could accelerate oxidation and temperatures rise, but uncertain water content and poor ventilation condition lessen the spontaneous combustion tendency.

以Fe2O3的硫化产物为典型样品，研究了硫化时间、水分、油品、硫及通风条件对硫化铁氧化升温特征的影响，结果表明，硫化时间长，适量的油品和硫以及良好的通风条件能够加速硫化铁升温过程，而一定的水分及不良的通风条件则降低了硫化铁的自燃倾向性。

Process and mechanism of electrodeposited Zn-Fe-Si02 composite coatings were studied, including some contents as follow: Potential-pH plots of Zn-H2O and Fe-H2O systems were drawn, and the thermomechanical analysis was made. Results showed that the region of zinc and iron's codeposition was wide, which provided theoretic basis for electrodepositing Zn-Fe alloy. But the balance potential of zinc was greatly different from iron's, so in order to make zinc and iron codepositing, some complexant must be added into electroplating solution.

本文研究了电沉积Zn-Fe-SiO_2复合镀层的工艺和机理，主要包括以下几个方面：绘制了Zn-H-2O系和Pe-H_2O系的电位-pH图，并对其进行了热力学分析，结果表明，锌和铁发生共沉积的区域很大，这就对电沉积Zn-Fe合金的可能性提供了理论依据，但是锌和铁的平衡电位差别较大，所以，必须在镀液中添入一定量的配合剂才能使锌铁产生共沉积。
