  3. 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生物因子的威脅程度相關的.著物種的加速絕滅,保護生物多性受到廣泛地關注.保護生物多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.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
  4. In this paper, chroma dc coefficients are selected as the carrier data because chroma dc coefficients are robust. also, alterable steps are used to select one part of the coefficients, so the watermark is imperceptible ; before watermark embedding, the watermark is divided into many parts, every part is individually embedded into one gop of the video, even if a gop is destroyed, the watermark can be extracted correctly, this methods promotes the robustness of the watermark ; in addition, in order to promote the security of the watermark, the user ' s id and password are used to generate chaos sequence by the chaos system which is created in this paper, later, watermark is mixed by the chaos sequence. also, the embedding position of the watermark bit is modified by one chaos sequence, so, unauthorized person can not extract or remove the watermark, since the embedding position is unknown

    文認為,色度dc系數是魯棒性常好的參數,因而選擇色度dc系數作為水印信息載體,同時,採用可變的步長選擇部分系數,保證了水印的隱形性;在嵌入水印時,文採用水印信息「網格劃分」 、各子塊獨立嵌入視頻的方案,由於水印信息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖組當中,即使某一圖組收到一定破壞,也能夠恢復水印信息,使水印的健壯性得到提高;此外,為了提高水印信息的安全性,在嵌入水印信息時,根據用戶輸入的id號和密碼,利用文構造的混沌系統產生的混沌序列對水印信息進行變換,同時,對每一水印信息比特的嵌入位置也採用了偽序列進行調整,這,未授權用戶不能提取水印信息,也難以擦除其中的水印信息,因為嵌入的位置是未知的。
  5. The analysis of this paper has produces following results : first, although monetary transmission theories have great difference from each other, these differences lie in the adjustment scope of the assets that they investigate ; second, the methods by which money affects economy are various, so it has a strong influence, however, the change in the amount of money will not only cause the change of the total demand, it will also lead to a change in total supply by corresponding expectancy, thus in a long term we ca n ' t rely on the expansion of money to expand the production ; third, third, with the deepening of the reform, the above monetary transmission mechanisms will play a more and more important role in china ' s economy, and the influence of currency to the economy will be more and more strong, but since the correlating micro - mechanisms is mot integral, we should be highly cautious when this change takes its place

    文的分析得出了以下的結論:第一,盡管各種貨幣傳導理論有很大的不同,但是這些不同可以歸結為它們所考察的資產調整范圍的不同;第二,貨幣作用於經濟的途徑是多種多的,因此它的影響力是常之大的,但是貨幣量的變動不僅會引起總需求的變動,而且會通過預期引起總供給的變動,因而在長期內不可能依靠貨幣的擴張來擴張產量;第三,著改革的深入,上述貨幣傳導制在中國經濟中的作用日益加強,貨幣對經濟的影響力也越來越大,因此從長期看,貨幣政策由信貸控制轉向貨幣量控制是一個必然的選擇,但是由於相應的微觀制尚未健全,這一轉變應高度謹慎。
