樹大根深
英文
a big tree strikes roots deeply. ; a big tree with deep roots; big trees have deep roots. ; the big trees strike deep roots-
They built a fire against the side of a great log twenty or thirty steps within the sombre depths of the forest, and then cooked some bacon in the frying - pan for supper, and used up half of the corn " pone " stock they had brought
在距離樹林深處二三十步遠的地方，他們緊挨著一根倒伏于地的大樹干生起火，架起平底煎鍋燒熟了些鹹肉當晚餐，還把帶來的玉米麵包吃掉了一半。They were eloquent in their distress ; but they presently discovered that the fire had eaten so far up under the great log it had been built against where it curved upward and separated itself from the ground, that a handbreadth or so of it had escaped wetting ; so they patiently wrought until, with shreds and bark gathered from the under sides of sheltered logs, they coaxed the fire to burn again
不過他們很快發現，原先那堆火已經把他們靠著生火的那根倒在地上的大樹干在它彎起離地面有些距離的地方燒得凹進去很深，因此有塊巴掌大的地方沒有被雨淋濕。於是他們極有耐性地想方設法，從那些有遮掩的樹下，尋來些碎葉樹皮做火引子，總算又把那堆火救活了。As most tree roots do not grow below about 2 m depth, even for large trees a 3 m rootball depth should be adequate
由於大部分樹根都無法于地深兩米以下的土層生長，所以，即使對大樹而言，三米深的根團，已經綽綽有餘。On the loess plateau, water is the main limiting factors for vegetation growth. root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments. even - aged stands of robinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation. investigatiing results showed that indicated that on all sites, root biomass decreased with depth, and the distribution depth of fine root was deeper than that of coarser root. the results of variance analysis indicated that there were great differences in root biomass among different diameter classes, and coarser root was the main sources of variance, and the root biomass, especially fine root ( < 3mm ) biomass on northern exposition sites was bigger than that on southern exposition sites. analysis of the vertical root distribution parameters, root extinction coefficient, indicated that the value of on northern exposition was more than 0. 982, while the value of on southern exposition was less than 0. 982, which indicated that the vertical root distribution depth of robinia pseudoacacia on southern exposition was deeper than that on southern exposition. and the distribution depth of fine roots ( < 1mm ) was deeper than that of thicker roots ( < 3mm ), which was in favor of the uptake of water and nutrients from deeper layers, helped the trees to adapt the arid environment, and promoted the growth of the upper parts of the tree
在中國西北黃土高原地區，水分是樹木生長發育的主要限制因子.根系分佈特徵由於反映了樹木對環境條件的利用程度而具有更加特殊的生態意義.本研究選擇陽坡和陰坡不同立地上年齡一致的刺槐林調查了根系分佈特徵.根系垂直分佈特徵的調查結果表明，在所有立地上，根系生物量隨著深度的增加而降低，其中細根的分佈深度大於粗根的分佈深度.方差分析結果表明:不同立地上不同徑級根系的分佈特徵也有明顯的差別，粗根是差異存在的主要原因，陰坡立地上的根系生物量，特別是細根生物量大於陽坡立地上的.對根系消弱系數的分析結果表明，陰坡立地上的根系消弱系數大於0 . 982 ，而陽坡立地上的根系消弱系數小於0 . 982 ，說明陰坡立地上刺槐根系的生物量在深層土壤中的分佈相對量更大一些.其中細根的根系消弱系數大於粗根的，這種根系分佈特徵有利於根系對深層土壤水分養分的吸收利用，進而促進樹木地上部分的生長發育.圖3表3參15Abstract : on the loess plateau, water is the main limiting factors for vegetation growth. root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments. even - aged stands of robinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation. investigatiing results showed that indicated that on all sites, root biomass decreased with depth, and the distribution depth of fine root was deeper than that of coarser root. the results of variance analysis indicated that there were great differences in root biomass among different diameter classes, and coarser root was the main sources of variance, and the root biomass, especially fine root ( < 3mm ) biomass on northern exposition sites was bigger than that on southern exposition sites. analysis of the vertical root distribution parameters, root extinction coefficient, indicated that the value of on northern exposition was more than 0. 982, while the value of on southern exposition was less than 0. 982, which indicated that the vertical root distribution depth of robinia pseudoacacia on southern exposition was deeper than that on southern exposition. and the distribution depth of fine roots ( < 1mm ) was deeper than that of thicker roots ( < 3mm ), which was in favor of the uptake of water and nutrients from deeper layers, helped the trees to adapt the arid environment, and promoted the growth of the upper parts of the tree

認為： （ 1 ）區域優勢是發展特色農業的基礎，特色農產品在產量、尤其在品質上與其他地區相比，需具有明顯的優勢； （ 2 ）商品經濟是發展特色農業的根本，特色農產品應該是綠色產品，且具有較強的市場競爭力和品牌效益，以及與市場容量相適宜的規模； （ 3 ）市場需求是發展特色農業的關鍵，需要通過大力發展農產品的深加工業，改變人們的消費形式來擴展和創造市場需求，樹立市場風險意識，加強對市場風險的分析判斷來避免市場風險，建立產業化組織與農民之間利益共用，風險共擔的經營機制，探索農業生產風險的商業保險機制，完善農產品價格保護和價格補貼制度，建立農產品風險基金制度來抵禦市場風險； （ 4 ）服務體系是發展特色農業的重點，建立市場化的農村社會化服務新體系，包括農產品的生產、加工、儲藏、運輸、銷售等系列化服務，尤其是要加強技術服務、信息服務和銷售服務。Regarding the lcm filling process as the newton fluid through fibrous reinforcements, the permeability of preform determines the saturating of resin in fiber, and has effects on the curing process and the quality of products. based on the darcy ' s law, the theoretical model of permeability measurement was established. and the influence of different testing methods and major process parameters such as fabric structure, fiber volume fraction, injection pressure, flow rate and resin viscosity on preform permeability were investigated in details
文中首先根據達西定律建立了滲透率測量的理論模型，深入研究了不同的測試方法及主要工藝參數（纖維織物織構、纖維體積含量、充模壓力、流動速度、樹脂粘度）對滲透特性的影響規律，發現多孔介質增強材料的滲透率主要取決于纖維織物的結構形式，預成型體孔隙分佈及其體積分數、壓實性對滲透率有較大的影響，提高充模壓力和流動速度可以縮短充模時間，在一定程度上可以提高滲透率。And keep the project title that i examined at that time, with being tattooed with a cutting edge paragraph that all participation is judged in memory printing on a piece of paper, let 6, 7 schoolmates choose according to self speciality 5 - 6 being in progress judge examine, require that everybody brings forward self positive and negative to every project strictly
記得當時，我和段文鋒把所有參與評審的項目標題列印在一張紙上，讓6 、 7個同學根據自己的特長選擇5 - 6個進行評審，並且嚴格要求大家對每個項目提出自己正反意見，不能只用好或壞來敷衍，因為我們深知，俱樂部形象的樹立需要平時一絲不茍的點滴積累，對其他俱樂部負責就是對我們自己負責。分享友人
