土壤水分测量论文

问:试说明在科研论文中一般测定的水分指标有哪些?测定指标的生物学意义是什么?其测定方法是什么?
  1. 答:水分指标有:
    总氮、总磷、氨氮、亚硝盐氮、硝酸盐氮、可溶解性的磷以及其他磷酸盐,还有化学需氧量COD、pH,类大肠杆菌群,TDS
    水饱和状态下总体原初渗透势、初始失膨点的总体渗透势、及该点所对应的相对含水量和相对渗透水含量
    叶水势,细胞汁液浓度或渗透势,气孔状况
    生物学意义:
    评定土壤的生态风险,预测总氮总磷等营养盐的变化趋势,预估植物的生理生长情况。合理灌溉,改善栽培环境的土壤条件和气候环境,保证植物的良好生长。
    测定方法:
    加热干燥法(包括常压烘箱干燥法,真空烘箱干燥法,红外线干燥法,微波加热干燥法,添加干燥辅助剂法)
    蒸馏法
    常压直接干燥法
  2. 答:总氮、总磷、氨氮、亚硝盐氮、硝酸盐氮、可溶解性的磷以及其他磷酸盐,还有化学需氧量COD、pH,类大肠杆菌群,TDS等。
    测定生物学的意义,个人认为是在于评定土壤的生态风险,以及预测总氮总磷等营养盐的变化趋势,预估植物的生理生长情况吧。
问:求毕业论文摘要翻译(麻烦英文高手,不要软件翻译)200分
  1. 答:The design of SPCE061A16-bit microcontrollers as micro-controllers, expansion of data acquisition modules, LCD, keypad modules, and munications module, the ponent circuit. The design is based on μ 'nSP IDE integrated development environment for system software development, design of the main program modules, data acquisition module, keyboard modules, munications modules. Through the system hardware and software debugging, to achieve the soil moisture measurements and data collection, display, save, and broadcast, and the system and PC munications, completed a test for soil moisture in the design and development.
  2. 答:Originally design and use SPCE061A16 location puter as the little controller, expand the data and gather module, LCD, keyboard module and munication module, make up the systematic hardware circuit. Originally design on the basis of μ ' nSP IDE integrated development environment developed to the systems soft ware, design main program module, data gather module, keyboard reveal module, munication module. Debug through the software and hardware of the system, can realize measurement and collection of the soil moisture data, reveal, save, and report, realize the munication of this system and PC, has finished design and development of a soil moisture tester.
