We analyzed the present situation of the concept of quality of distance education and the root of the problems. we discussed in detail the concept of quality of polybasic distance education, pointing out the critical issues that the concept needs to address in actual practice
分析了遠程教育質量觀的現狀及存在問題的根源，並對多元化遠程教育質量觀進行了較為詳細的評述，提出了多元化遠程教育質量觀在指導實際工作中需重點顧及的問題。 -
The results showed : the relationships among cover of herbaceous layer, cover of liver moss layer, thickness of liver moss layer, thickness of root system twine layer and the distance between seedlings and adjacent tree were positive correlation ; the relation between litter and tile above five variables were negative correlation ; the variables of micro - habitat affecting seedling in the picea schrenkiana stand were generalized with moss, herbaceous, spatial distance, humus and litter ; litter and spatial distance between seedlings and adjacent tree were the most primary factors of micro habitat affecting regeneration of one year seedling
結果表明：天山雲杉林分中草本層蓋度、苔鮮層蓋度、苔鮮層厚度、根系盤結層厚度、幼苗距大樹的距離5個環境變量之間為正相關；枯落物與草本層蓋度、苔蘚層蓋度、苔蘚層厚度、根系盤結層厚度、幼苗距大樹的距離為負相關；天山雲杉林微生境綜合因子可概括為「苔蘚」 、 「草本」 、 「空間距離」 、 「腐殖質」和「枯落物」 ；影響一年生幼苗更新最主要的微環境綜合因子為「枯落物」和幼苗距大樹的「空間距離」 。 -
Root - mean - square end - to - end distance
均方根末端距 -
We use these numbers because the actual distance to move diagonally is the square root of 2 ( don ' t be scared ), or roughly 1. 414 times the cost of moving horizontally or vertically
我們使用這些值，因為斜角移動的實際距離是2的平方根（別害怕） ，或者大概1 . 414倍的水平/垂直的移動代價。 -
The results indicate that the time of press influences sawtooth distortion greatly, but infects sawtooth less. root of the sawtooth made by the method of static simulating rolling have no changes hardly, and from the upper distance the changes became, then on the top the sawtooth curves to the opposite direction
結果表明：壓制時間對齒形的變形影響較大，對齒型的影響很小；模擬軋輥壓制的鋸齒，根部一段幾乎沒有變化，是從一段距離開始變形，然後在頂端向相反的方向彎曲；壓製成型后，鋁板厚度的變化很小。
