  1. This is so because climbing plants are likely to encounter intensive - changing environmental condition during their growth ( especially change of illumination ). secondly, there is a large proportion ( 30 - 40 % ) of climbing plants which belong to dioecism, and hence a gap between male and female plants on morphology, biological characteristic, economic value and so on. this dissertation focuses on herbaceous climbing plants, perennial or annual species such as dioecious trchosahthes kirilowii maxin and dioscorea opposita thumb, and monoecious luffa cylindrical ( l ) roem, it attempts to discover how climbing plants adapted to various environments and the mechanism of adaptation from aspects of physiological and reproductive ecologies at present, due to overuse of chlorofluorocarbons ( cfcs ), the ozonosphere has become thinner and thinner, and the ultraviolet - b ( uv - b ) radiation has increased considerably

    而攀援植物本身是一類理想的植物行為生態學研究材料：第一，攀緣植物由於受攀緣能力和支柱木資源的限制，在生長過程中通常要遇到強烈變化的環境條件（特別是光照） ；第二，攀緣植物中具有較高比例的雌雄異株類型，通常佔地區攀緣植物種類的30 40左右，不同性別的植物在形態學及生物學特性、經濟價值等方面存在一定的差距，因此，本文以雌雄異株攀緣植物栝樓（ trchosahtheskirilowiimaxim ） （葫蘆科多年生草質藤本植物）和山藥（ dioscoreaoppositathunb ） （薯蕷科薯蕷屬植物） 、雌雄同株異花攀緣植物絲瓜[ luffacylindrical （ l ） roem ] （葫蘆科一年生攀緣草本植物）為材料，試圖從生理生態學及生殖生態學角度揭示攀援植物如何適應不同生境及其機理。
  2. The inclusion behaviors of b - cyclodextrin with some aromatic amino acids such as l - phenylalanine, l - tyrosine and l - tryptophan were studied via ultraviolet and fluorescent spectrometry. the results indicated that inclusion complexes of - cyclodextrin with aromatic amino acids could be formed and the inclusion behaviors were affected by the amount of - cyclodextrin, temperature and ph value

    本文研究了?環糊精與芳香族氨基酸l ?苯丙氨酸、 l ?酪氨酸和l ?色氨酸之間的包合作用，考察了?環糊精用量、溫度、時間和ph值等因素對包合作用的影響。
  3. The infrared results showed that the ir characteristic value l080cm - lof cubic crystal sio, and the absorption peak 460cm - l of mgf, caused by the interaction between f - - mg ' + - p elastic vibration and photon radiation, appeared in the ir spectra. ellipsometric analysis showed that the typical absorption peaks 58lnm, 589nm and 606nm, resulting from the surface plasma resonance of cu panicles and reflecting the absorption on composite film system, appeared in the extinction coefficient k curves of cu ( voll5 % ) mgf, cu ( vol20 % ) mgf, and cu ( vol30 % ) mgf, cermet films, respectively. with the component of cu increasing, the peak site presented red shift, which was in accordance to the results of ultraviolet - visible spectra

    橢偏測試分析表明： cu （ vol15 ） mgf _ 2 、 cu （ vol20 ） mgf _ 2和cu （ vol30 ） mgf _ 2樣品的消光系數k曲線中出現了反映復合金屬陶瓷體系吸收的由cu金屬顆粒表面等離子體共振引起的吸收峰，峰位分別為581nm 、 589nm和606nm ，呈現紅移，這些與紫外-可見光譜測試結果相一致；此外， cu - mgf _ 2復合納米金屬陶瓷薄膜光學常數的實驗值與考慮尺寸效應修正過的mg理論值總體上符合得很好。
