Mongolica young stand, secondary natural forest, and the mixed forest of larix olgensis and fraxinus mandshurica rupr. countermeasures for controlling soil degradation were also recommended. the study got following results : ( 1 ) from young stand to mid - age of larix olgensis, with the closure of canopy and the decrease of undergrowth vegetation cover, soil acidity, enzyme activity, total inorganic phosphorus, available k, soil moisture and total porosity decreased significantly ; while soil organic matter content, humus component content, the amount of three main types of microbes, acid phosphatase activity, and bulk density in rhizosphere soil and non - rhizosphere soil increased with the increase of the amount of forest floor litter ; from mid - age stand to near mature stand, with the decrease of stand density and crown cover as well as the restoration of undergrowth vegetation after preliminary thinning, soil organic matter content, fulvic acid, exchangeable acidity, exchangeable aluminium, neutral phosphatase activity, total amount of inorganic phosphorus, the amount of actinomycetes, soil moisture, and total porosity in rhizosphere soil and non - rhizosphere soil apparently increased ; from near matu re stand to mature stand, soil activity acidity, organic matter content, humus component content, available phosphorus, total amount of amino acid, available k, soil enzyme activity, soil moisture, and total porosity in rhizosphere soil and non - rhizosphere soil decreased, but total phosphorus, soil acidity ( in particular, exchangeable aluminium ), and bulk density increased
結果表明： （ 1 ）從落葉松幼齡林到中齡林，隨著林冠的郁閉和林下植被蓋度的急劇下降，林地土壤酸度、土壤酶活性、無機磷總量、速效鉀、土壤水分含量、總孔隙度呈明顯下降趨勢，而根際和非根際土壤有機質含量、腐殖質各組分含量、三大類微生物數量、酸性磷酸酶活性和土壤容重隨著凋落物的增加呈明顯上升趨勢；從中齡林到近熟林，由於撫育間伐，林分密度及郁閉度下降，林下植被蓋度逐步得到恢復，根際與非根際土壤有機質含量、富里酸、交換性酸、交換性鋁、中性磷酸酶、無機磷總量、放線菌數量、土壤水分含量、總孔隙度呈明顯的上升趨勢；從近熟林到成熟林，隨著林齡的增大，根際與非根際土壤活性酸、有機質含量、腐殖質各組分含量、有效磷含量、氨基酸總量、速效鉀、土壤酶的活性、土壤水分含量和總孔隙度呈下降趨勢，而根際與非根際土壤全磷含量、土壤酸度（特別是交換性鋁）和容重呈增加趨勢。 -
L - threonine is a neutral, genetically coded amino acid. it is essential in human nutrition. it is a colorless crystalline amino acid that is derived from the hydrolysis of protein
蘇氨酸是一種由蛋白質水解而成的中性氨基酸，無色晶狀，是人類必需的營養成分。 -
L - tryptophan is a neutral, genetically coded amino acid. iit is essential in human nutrition. formed from proteins during the digestive process by the action of proteolytic enzymes
色氨酸是一種重要的中性必需氨基酸，在消化過程中，通過蛋白水解作用酶的運動而由蛋白質形成。 -
L - glutamine is a non - essential, neutral, genetically coded amino acid. occurring widely in plant and animal tissue and produced commercially for use in medicine and biochemical research
谷酰胺是一種非必需的中性氨基酸，大量的含于動植物組織，大量生產用於醫藥和生化研究。 -
Part ii screening of tnfa mimotopes from phage display peptide library : based on the results of screening tnfa binding - peptides, we have tried to use neutral tnfa mcab j1d9 as target to screen tnfa mimotopes from c7c phage display peptide library, which may be another form of antagonist for tnfa, and the mimotopes were identified by sandwich elisa. after 3 rounds of screening, we got 9 phage clones identified as positive clones which can bind with mcab j1d9. we also identified the binding between mimotopes and tnf receptor by competitive elisa, and the results showed strongly binding. the amino acid sequence results shown three different sequences : c - rrpaqsg - c - nkhnrki - c and c - rgmsrki - c
在對噬菌體環七肽庫進行三輪親和性篩選后，隨機挑選20個噬菌體克隆， elisa鑒定出9個陽性克隆，經dna測序推出三種氨基酸序列： c - rrpaqsg - c 、 c - nkhnrki - c和c - rgmsrki - c ，其中優勢克隆序列為c - rrpaqsg - c ；鑒定結果顯示陽性克隆能夠與tnf受體結合，並且能夠阻斷tnf與受體的結合，提示篩選得到的環七肽克隆展示肽具有tnf的抗原性及與tnf受體結第一軍醫大學顧士學位論文合的特性，為tnfa表位模擬肽。 -
L - alanine is a neutral, genetically coded amino acid. it is a crystalline amino acid, that is a constituent of many proteins
丙氨酸是一種晶體狀的中性氨基酸，是許多蛋白質的組成成份。
