  1. Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers

    發展了「土壤水分背景」的概念，並以之為基礎對其各個方面進行了研究，使之形成一個相對獨立和完整的體系，主要包括黃土高原土壤水分的背景值、土壤水分背景的區域分異、坡面分異、鑲嵌結構及其季節分異等： （ 1 ）由於植被生長發展、演替的基礎階段是天然草被群落，故認為黃土高原的土壤水分背景在概念上是特指該區天然草被群落下的土壤水分狀況； （ 2 ）黃土高原的土壤水分背景值，根據植被地帶的不同表現出自南向北逐漸降低的規律：森林地帶3米以下土層水分背景值普遍穩定地高於12 ，森林草原地帶4米以下土層水分背景值穩定大於6 ，且均隨土層的加深水分含量逐漸增加，而草原帶的土壤水分背景值自土表至底土層一直在4 6之間徘徊。
  2. The study paid attention to the change of teacher ' s sense of teaching efficacy teaching motivation and occupational stress under such realistic background. by analysis and explanation of investigation data, the study concludes the results as follows : 1 after implement of curricular reform, general teaching efficacy of teachers who have joined curricular reform compared to their past or to of what teachers who have n ' t joined curricular reform goes up significantly, while personal teaching efficacy ( significantly ) declines ; 2 after implement of curricular reform, intrinsic motivation of teachers who have joined curricular reform compared to their past ( significantly ) presents descending trend, while their outer motivation ( significantly ) rises apparently. so that their intrinsic motivation and outer motivation are significantly much higher than of what teachers who have n ' t joined curricular reform ; 3 after implement of curricular reform, occupational role and personal stress of teachers who have joined curricular reform compared to their past or to of what teachers who have n ' t joined curricular reform goes up significantly, while their relaxation of personal resource significantly declines, but have no remarkable difference at other aspects ; 4 the sense of teaching efficacy teaching motivation and occupational stress of teachers which belong to different characteristic and category exists remarkable difference before and after new curricular reform ; 5 teachers " sense of teaching efficacy teaching motivation and occupational stress tie together tightly, while the interaction of teaching motivation and occupational stress is prominence, occupational stress directly influences teaching motivation, and indirectly influences the sense of teaching efficacy

    通過對調查數據予以分析和說明，本研究得到如下結論： （ 1 ）課程改革以後，參與課改的教師無論與自身縱向相比，還是與未參加課改的教師橫向相比，其一般教育效能感顯著上升，而教師的個人教學效能感則（顯著）下降； （ 2 ）課程改革以後，參與課改的教師與自身縱向相比其內部動機有較為顯著的下降趨勢，外部動機則有顯著地上升趨勢；其內部動機和外部動機都（顯著）高於未參加課改的教師； （ 3 ）課程改革以後，參與課改的教師無論是與自身縱向相比，還是與未參與課改的教師橫向相比，其「職業任務」和「個體緊張反應」方面均呈現（非常）顯著地上升趨勢，而在「個體應對資源」方面除休閑是顯著降低外，其餘無顯著的差異； （ 4 ）不同特徵和類別教師的「教學效能感」 、 「教學動機」和「職業緊張應對」在課改前後的變化狀況上存在（顯著）差異； （ 5 ）教師教學效能感、教學動機和職業緊張應對密切聯系，教學動機與教學效能感相互作用顯著；而職業緊張應對直接顯著影響教學動機，間接影響教學效能感。
  3. There is great difference between the content of carotenes of different parts in different varieties : the content of carotenes of phloem is ' higher than xylem ' s to a great extent, and the results showed a descending trend of the content of carotenes from the top of carrot to lower parts

    所以對這些品種建議提早採收，以便胡蘿卜素含量保持在較高的水平。胡蘿卜次生韌皮部中的胡蘿卜素含量極顯著的高於次生木質部，胡蘿卜肉質根中自上而下胡蘿素含量呈現遞減的趨勢，胡蘿卜素在胡蘿卜中主要分佈於次生韌皮部和肉質根的上部。
