  1. Fractal coding has been proved useful for image compression. it is also proved effective for content - based image retrieval. in the paper, we present a block - constrained fractal coding scheme and a matching strategy for content - based image retrieval. in this coding scheme, an image is partitioned into non - overlap blocks of a size close to that of a query iconic image. fractal codes are generated for each block independently. in the similarity measure of fractal codes, an improved nona - tree decomposition scheme is adopted to avoid matching the fractal codes globally in order to reduce computational complexity. our experimental results show that our coding scheme and the matching strategy we adopted is useful for image retrieval, and is compared favorably with other two methods tested in terms of storage usage and computing time

    分形編碼在圖像壓縮方面取得了很好的效果，同時，分形編碼也能夠用於基於內容的圖像檢索.本文提出了一種基於塊限制的分形編碼演算法和匹配策略，並將它們用於圖像檢索.在我們編碼演算法中，圖像會被預先分成互相不重疊的子圖像塊，然後對這些子圖像進行獨立地分形編碼，從而獲得整幅圖像的分形碼.該編碼演算法能夠在很大程度上減少編碼時間.在進行圖像間相似性的匹配時，我們採用改進的基於九叉樹的分配策略，從而避免全局地進行分形碼的匹配，減少了計算量.實驗結果說明，我們的編碼演算法和匹配策略能夠比較有效地應用於基於內容的圖像檢索，在計算時間和存儲時間上都優于實驗中其它兩種方法

  4. 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

After january, 2003, “ the law of government procurement ” came into force, both concentrative purchase and dispersive purchase are use by government, which starts an new trend of government purchase progress, using concentrative purchase to do more large quantity purchase, dispersive purchase is used less and less, it only used to do little quantity purchase. the list of government purchase has become longer and longer, the variety of materials and the quantity of materials has increased so sharply. our country ’ s government purchase has made a great progress, but but we still need to take notice of the other side of the fact, there are two important issues, the first is the obstacle of the reforming process in the field of public finance system ; and the second is the kinds of problems occurred in the process of government procurement

    政府采購制度改革是我國公共財政改革的重要組成部分，引入我國從試點到推廣實施僅有十年的時間，卻取得了巨大的進展， 《政府采購法》在2003年1月開始實施后，我國採用集中采購與分散采購相結合的政府采購方式，開始了我國政府采購的集中化趨勢進程，從早期分散采購演變為大批量的集中的采購方式，當然，小批量分散采購也結合其中，列入政府集中采購目錄的物資種類與采購數量大大增加，取得了巨大的進展，卻也存在著不少的問題，具體表現為政府采購過程中出現的各種操作性問題和政府采購制度推進的障礙，以及政府采購的環境效益問題，操作性問題和政府采購制度推進的障礙問題本質上可歸納為兩方面，即內在因素，這是事前性的，偏重於制度性、體制性等根本問題;外在因素，這是管理操作層面的因素，政府采購的環境效益問題是由政府是否采購綠色產品，推動綠色產品在社會的使用而引出的，於是，對政府采購集中化趨勢中所暴露出的問題進行分析，找出問題的根源以探尋解決的思路及對策就顯得尤為急迫。

    第一，對高速公路收費制度的效率和存續期限利用一個經濟學模型進行了研究，得出結論：只有當一個國家的政府在財政壓力下沒有能力修築公路時才會採取收費的方式，當然在這個表面現象下面掩蓋著這樣一個基本的事實：政府是在免費制度下的轉移損失與收費制度下的福利損失之間進行權衡，只有當政府認為目前稅率足夠高了，沒有再行征稅的餘地時，才會選擇收費制度，而足夠高的稅率和民眾不允許再行征稅意味著再行征稅的轉移損失大到了一定的程度。
