With the acceleration of extinction of species, biodiversity conservation is extensively concerned. the extinction of species is concerned with the degree of threat by biotic and abiotic factors. so, taking action to preserve plant species is very necessary and paramount before their extinction. one of the most effective biological techniques to conserve the biodiversity is the establishment of genebanks, i. e. ex situ conservation. the elucidation of various factors that regulate seed viability and vigor in storage is essential. an ideal condition to prolong the longevity is mainly depended on seed water content, temperature, humidity and types of containers used during storage. the optimum stage of seed maturity, harvesting techniques and processing, in addition to physiological features such as degree of dormancy, also play key roles in seed storage. certainly, desiccated seeds deteriorate with time even under extremely good genebanking conditions. according to seed storage behavior, it is necessary to consider three principal factors : storage environment, storage duration and plant species which will affect seed survival under good genebanking conditions. the present review is an attempt to discuss the importance of the aforementioned aspects of seeds in detail in order to conserve plant germplasms ( especially wild rare and endangered plants ) for ex situ conservation through seed - gene bank
一個物種的滅絕是與其受生物因子和非生物因子的威脅程度相關的.隨著物種的加速絕滅，保護生物多樣性受到廣泛地關注.保護生物多樣性的最有效的生物技術之一是建立種子基因庫，進行遷地保護.種子庫理想的貯藏條件主要取決于種子含水量、貯藏環境（如溫度和濕度）和貯存種子的容器.進行種子貯藏，了解種子生命力和活力的影響因子的作用機理是十分重要和必要的.除了種子自身的生理特徵外，種子的貯藏壽命與種子成熟度、收獲技術、加工處理方法也是息息相關的.即使在最適的庫存條件下，種子也會隨時間發生劣變.因此，必須根據種子特定的貯藏行為，加以考慮影響種子存活的3個主要方面（貯藏環境、貯藏期和植物種類）而選擇有效的貯藏方案.本文試圖討論種子貯藏生理的幾個重要方面及其需解決的技術問題，以便更好地通過種子基因庫，長期有效地保存植物種質資源 -
Red tide occurs randomly, with short duration and large incidence. airborne hyperspectral remote sensing technique can play an important role in red tide ' s monitoring. and the precondition is to acquire in situ spectral data of red tide, to grasp red tide ' s spectral characteristics by data processing and analysis and to set up spectral library of different dominant species of red tide
赤潮是海水中的浮游生物在一定條件下過度繁殖或聚集致使海水變色的一種生態異常現象，因其具有隨機性、突發性、持續時間短、影響范圍大等特點，客觀上要求利用航空高光譜遙感技術對其進行監測；但首要的前提與基礎性工作是大量獲取赤潮水體的現場光譜數據，通過處理與分析，掌握其光譜特性，不斷充實赤潮優勢種類的光譜數據庫。 -
Na / cl - dependent gaba transporters play an important role in controlling the concentration of gaba in the synaptic cleft, and thus they control the intensity and duration of synaptic transmission of gaba
依賴na / cl的gaba轉運蛋白對控制gaba在突觸間隙中的濃度起到重要作用，並因此而控制了gaba在突觸傳遞中的強度和持續時間。 -
However domestic unmature security marbet restrict amc ' s free shares transfer. my opinion is to improve and regulate by law in the course of d - to e. firstly, it is necessary to grasp d to e principle accuratly and construct strict qualification system, secondly, it is important to guarantee amc to enterprise system can keep amc ' s as shareholder control of d to e enterprise, and improve continuously amc ' s management level and efficiency. it is necessary to make special regulation about the duration periods and vavle of amc ' s egutity in legislation to sustain amc benefit, moreover, 13 to e also coordinate with state - owned ' s out - strategy and adjust ownership through social and. private cash input, these also help solve the problem of uvclear state - owned ownership entity ; at the same time, it is necessary to improve security market to widen the ways of share transfer, to be outward transfer as main transfer way, to cultivate institutional investor and reform equity system ; at last it is important to difine correctly bovernment ' s role and play its role. government should be in the nationwide view to organize, coordinate balance support regulate to guarantee d to e ' s performance
筆者認為，債轉股實施過程中，應依照法律規范予以完善和制約，首先應準確把握其操作原則，特別注意嚴格把好債轉股的準入關;其次，切實發揮金融資產管理公司的職能作用，促使企業轉換經營機制建立現代企業制度，要確保金融資產管理公司作為股東對債轉股企業的最終控制權，不斷提高金融資產管理公司的運作水平和效率，並且在立法上對債轉股中的股權的存續和價值的保護進行特別規定，以維護金融資產管理公司的合法權益;再者，債轉股還要與國有經濟的戰略性退出相結合，進行必要的產權結構調整，通過引入社會資金、民營資本等其他成分徹底解決國企產權主體虛位和產權不明晰的現象;同時，要完善資本市場，積極拓寬股權的退出通道，把對外轉讓作為股權的主要退士方式，培育機構投資者，改革股權制度;最
