蜂膠中蘆丁楊梅酮槲皮素莰菲醇芹菜素松屬素苛因高良姜素含量的測定方法液相色譜-串聯質譜檢測法和液相色譜-紫外檢測法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 ] 。Conclusion pinocembrin and its derivatives may be usefully antimicrobial candidate drugs
結論松屬素及其衍生物有可能成為新型結構的抗菌藥物。Aim to synthesize pinocembrin and its derivatives, and to study their antimicrobial activity
摘要目的合成松屬素及其衍生物，研究其抗菌活性。( 3 ) the free - standing porous silicon films with continuous porous structure were prepared on single crystal silicon wafer by the method of anodic oxidation and electrochemical etching - electropolishing, and firstly used as the anode materials for lithium ion secondary batteries. the capacities of lithium ions storage and the process of charge and discharge of this nano - silicon anode materials as well as the influence of the structure of ps on behavior of storing lithium ions were inspected at length. on the other hand, through the process of charge and discharge in cells, the lithium of light metal element could be electrochemically doped into ps at different doping levels
胡勁松河北師死大學碩士學位論文（ 3 ）利用陽極氧化法在單晶硅基底上制備了多孔硅自支撐膜，並首次將這種具有連續多孔結構的硅材料用作了理離子電池的陽極材料，考察了這種納米級硅陽極的儲鉀性能和充放電過程，分析了材料結構對其儲理行為的影響；另一方面，利用這種電池充放電過程在多孔硅中電化學引入了不同點綴程度的輕金屬鉀元素，考察了鉀點綴對多孔硅自身結構，及至性質所帶來的影響，提供了一種通過電化學方法插入埋離子從而連續調整多孔硅發光性質的有效方法。The community productivity, structure and succession are significantly influenced by global climate changes. this study focused on soil respiration rate of stipa baicalensis grassland by using dynamic infrared gas absorbed method. we analyzed diurnal pattern of soil respiration rate and the influences of surface soil temperature and water content for this parameter, then compared the differences between day and night soil respiration rates, and explored the correlations between aboveground and underground biomass with the soil respiration
溫帶的半乾旱、半濕潤區草甸草原屬于過渡氣候影響下形成的植被類型，對環境氣候條件變化十分敏感，為了揭示半乾旱、半濕潤區草甸草原生態系統土壤碳素釋放規律及其對主要環境因子的響應，本研究採用動態室紅外氣體吸收法測定松嫩草甸草原典型群落? ?貝加爾針茅群落土壤呼吸速率，分析了土壤呼吸速率日變化規律及表層土壤溫度和含水量對土壤呼吸速率日變化的影響，比較了土壤呼吸速率的晝夜差異，探討了地上生物量和地下生物量與土壤呼吸速率之間的相關關系。The results are mainly as follows : sticky quality, tuber structure, the loose and tense degree, unit weight, ph value ( decreases in the few conditons that resulting acidity strengthening ), alkalinity increases in the same soil level, root quantity and macro - element content decreases ; there has a extraordinary difference between k, ca and mg, especially for pb and cd which shows that the collecting function of soil enhances under the disturbence conditon, and other micro - elements, such as zn > mn, cu, ni get decreasing. tourism activity is one of the key reasons for water body pollution. to different recreation types, the pollution degree has the obvious difference
各景觀區所取樣點中，土壤理化性旅遊破壞區所受影響最大，呈現出質地粘重、結構變差（以塊狀為主） 、同一層次土壤松緊度增大、根系變少、容重增大、土壤ph值增大（也有個別ph減少，以致酸性增強） 、堿性增強、大量元素降低，其中對k 、 ca 、 mg影響中有顯著性的差異（又以游道類影響最為顯著） 、重金屬元素（ pb和cd ）明顯增多、顯著性的差異最為明顯，其它微量元素（ zn 、 mn 、 cu 、 ni ）逐漸減少，表明旅遊活動干擾後土壤對pb和cd富集作用增強等特點。分享友人
