Melatonin ( n - acetyl - 5 - methoxytryptamine ) was discovered by a lerner and his colleagues [ l ] as the principal hormone of vertebrate pineal gland, an unpaired appendage of the brain in most vertebrates and named by him after its effects on amphibian melanophore. however, it is now known that many cells and tissues synthesis and the nature of organisms, melatonin is secreted in the night, thus, melatonin is identified as an endocreine index of the darkness and referred to as darkness hormone [ 3 ]. melatonin has aslo been called by other names, such as nature ' s sleeping pill for it role in sleep - wake cycles, and circadian glue for its increasing importance in the regulation of circadian and circannual physiological and behavioural functions, moreover it is also involved in the regulation of the immune respone and various cns activies, in the last decade, considerable attention has been devoted to the pharmacology of melatonin in view of its potential applications in various therapeutic areas
褪黑素（ n -乙酰- 5 -甲氧基色胺， melatonin ，簡稱mt ） ，由lerner和他的同事們發現[ 1 ] ，后來根據它對兩棲動物黑色素細胞的影響而命名，是脊椎動物松果腺分泌的一種重要激素。松果體在大多數多脊椎動物中是一個孤立的附屬器官。然而，現在眾所周知很多細胞和組織合成mt ，若不考慮合成的位點和機體的屬性， mt在晚上分泌，正因如此， mt被認為是一種黑暗的內源性指標，被稱作黑色激素[ 3 ] 。 -
In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints, this thesis made com land, fallow land, orchard, grass land as experimental field in black soil region jlau, which carried out experiment by applying different amounts of n and p fertilization in corn field. by means of collecting the samples of rainfall runoff, erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field, we study the effect of surface runoff on n and p nutrient and fertility degeneration. the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p, in which rainfall and rainfall intensity were more important, while rainfall intensity is the most important meteorological phenomena factor
針對當前黑土利用現狀，本文借鑒眾多學者的研究方法和觀點，在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地，在玉米區進行了不同數量的施肥，通過野外試驗，採集一年自然降雨產流及泥沙樣品，同時採集降雨前後的耕層土壤樣品，研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響，結果表明：土壤侵蝕和氮磷的流失受諸多因素的影響，降雨量、降雨強度是重要因子，而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子，特別是暴雨，暴雨徑流中氮磷濃度較平時高得多；隨作物生長，覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異，氮磷流失都表現為顯著的差異。 -

The fitness of four negative electrode materials such as al, fe, zn, cd, and of six membranes materials : microfiber glass mat separator, polyethylene, polypropylene, polyvinyl chloride, vinylon, soapnated cellulose acetate, and of four current collects : carbon fiber ; nickel foam ; nickel foam sthongthened by iron wire net, punched silver grid in the super - iron alkaline batteries was comparatively studied. the influence of two storaged method ( with and without electrolyte ) and two impurities ( zno, fe ( oh ) 3 ) to the experiment cell ' s self - discharge nature was also comparatively studied. at last, the nature of discharge. structure and electrochemistry of experimental cell with k2feo4 as cathode active material prepared by three different methods : high temperature reaction, hypochlorite oxidizing and electrolysis, was comparative ly studied. we can conclude : i ) the open - circuit potential and the flat of work potential and the percent of capacity of k2feo4 till 1. 0v during the discharge at constant load of experimental cells decreased by the order of al / k2feo4, zn / k2feo4, cd / k2feo4, fe / k2feo4. as for the nature of charge - discharge cycle, cd / k2feo4 fe / k2feo4 zn / k2feo4. in water solute electrolyte, although al / k2feo4 can n ' t be used as storage battery, it have great potential as primary cell or storage cell from the aspect of its discharge capacity. discharge power
採用組裝實驗電池、 x -射線衍射（ xrd ）和循環伏安（ cv ）的方法，從實驗電池的放電特性、充放電循環特性、自放電特性，不同高鐵酸鹽的結構特性和電化學特性幾個方面，對4種金屬負極材料（ al 、 fe 、 zn 、 cd ） 、 6種隔膜材料（復合玻璃纖維、幅射接枝聚乙烯、改性聚丙烯、聚氯乙烯、維尼綸無紡布、皂化再生纖維素） 、 4種集流體材料（泡沫鎳、以鐵網為加強層的泡沫鎳、切拉銀網、炭纖維編織網）在堿性高鐵電池中的適用性進行了比較研究；對2種雜質組分（ zno 、 fe （ oh ） _ 3 ）和2類不同貯存方式（干、濕）對實驗電池自放電特性的影響進行了比較研究；對3種方法（高溫固相反應、次氯酸鹽氧化、直流電解）所制k _ 2feo _ 4的實驗電池的放電特性、結構特性和電化學性能進行了比較研究。 -
