With economy development, the contradiction of expansion qf cities and reduction of rural land. existence and development of peasant, and modernization and peasant small production are apparent obvious, countryside land using rights have gradually changed : peasant are deprived of land using rights by the nation levying land and by the collective collecting land, and the voluntary circulation among peasants because of manpower shifting make land collected with small scale etc. the circulation of land using rights is the necessary tendency, but how to ifiake the circulation in the order, protect peasants interests and national profits mostly are always concerning the subject about which many scholars and country worker are concerned
而農民唯一的生活保障「土地」 ，在經濟發展中成了「唐僧肉」 ，農民土地使用權肆意剝奪、無序流轉非常嚴重。的確，隨著經濟發展，城市擴張與農村土地減少的矛盾、農民生存與發展的矛盾、農業現代化與農戶小生產的矛盾突顯，農村土地使用權不斷的發生變化：國家通過征地使農民永遠失去土地使用權，集體返租倒包集中土地使農民失去土地使用權，農戶之間由於勞動力轉移自願流轉使土地小規模集中，等等，土地使用權流轉是我國經濟發展的必然趨向。 -

According to thermal state similitude model experiment of the langya mountain hydropower station, we adopt different velocity of air ventilation and exclude air proportion of upriver and downriver, this paper contrast the air distribution of the dynamo floor on each method, and educe the best projects of arch crest supply air that adapt to langya mountain hydropower station ’ s dynamo floor : g = 17. 4 10 ~ 4m ~ 3 / h, 22 vents, d = 600mm, the scale of volume 1 : 3, t0 = 16. 9. it ’ s also thought that improved any side of volume can reduce its temperature. when study on the air supply of langya mountain hydropower station ’ s underground dynamo floor by cfd software, it proved that cfd software is correct when compare with model experiment. when arrange the number of 5 kinds of vents, it concluded that the number of vents 14 to 22, it can ’ t change velocity, in 36 to 40 can lead to reduction of velocity. when vent in 14 to 36, the parameter kt doesn ’ t change, when the number is as large as 36, kt reduces
在此基礎上，模擬了5種風口布置方案和送風量的改變對發電機層溫度場和速度場的影響，獲得了些可供參考的結論:在風量和送風速度不變的條件下，風口個數在（ 14 ~ 22 ）小范圍變化時，工作區平均風速基本不變，大幅度增加風口個數（ 36 ~ 44 ）就會導致工作區平均風速的降低，風口數在14 ~ 36之間對工作區的溫度不均勻系數影響不大，當風口數> 36時，溫度不均勻系數隨著風口數的增多而變小，速度不均勻系數一直隨著風口數的增加而減少;在風口布置和尺寸不變的情況下，送風量變化時，工作區平均溫度隨送風量增大而降低，平均溫度的降低量逐漸趨于減少，能量利用系數先是隨著送風量的增加而增大，后隨送風量增加而減少。 -

The reason that ec can improve the competitive ability of firms lies in the fact that, the cost of firms can relatively contracted, and the firms have the competitive advantages of enlarging without boundary. the relatively contracting of firms cost means, the effect of diminishing of managerial costs can simultaneously occurred in the fields of production costs, marginal costs, and transaction costs, with the results that the barriers of competition was founded because of the higher transaction costs of provision regarding to the businessmen of productions and services, which are caused by the reduction of production costs rendered by higher productivity, and of managerial costs rendered by the effect of substitution of soft manufactory technology. the relative enlarging of the optimal bound of firms means, that the firms can share managerial costs through the effect of scale of management by the employment of ec, that the scale of firms is enlarged while the managerial costs are cut as a result of the distributing of managerial costs to every liners and proceeds of the firms, which means that the same managerial costs can be used by larger - scaled firms
電子商務之所以能提高企業競爭力，是因為企業成本相對收縮和企業的無邊界擴張競爭優勢，所謂企業成本相對收縮即邊際成本遞減，這種邊際成本遞減效應可以同時出現在生產成本、管理成本和交易成本三個領域中，電子商務通過提高勞動生產率來降低生產成本，柔性製造技術的替代效應降低了庫存管理成本，與此同時，電子商務減少企業與消費者之間的環節，縮短路徑距離而降低企業內外的交易成本，提高了企業產品和服務分銷商改變供貨方式的交易成本，使之形成企業競爭的壁壘；所謂企業最優邊界的相對擴張，是指由於規模管理效應即電子商務運用信息技術使企業以低信息成本共享管理成本，使企業總體管理成本分攤到各個管理環節和流程中，企業規模擴大而邊際管理成本逐漸下降，相同的管理成本可用於管理更大規模的企業，即隨著電子商務在企業中的應用，企業的最優邊界相對擴張了。 -
