  1. At the surface of the pollen grains there are three types of aperturates, including three porates type, three colpates type and three porate - colpates type ; and four types of sculpture, namely, reticulate, striate, striate - reticulate and verrucate. the upper epidermal cells of the leaves of 12 species plants are detected with hpias - 1000 image analytic system through the treatment of binarization, and the experimental methods are proved stable. the results indicated that the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slf ) of the epidermal cells of the middle lamina in the third node of leaves starting from the lowerest part of the stem have a relative constant range and could distinguish from each other. oieanolic acid, l, 5, 8 - trihydroxy - 3 - methoxyxanthone and swertiamarin are separately detected on the tlc, and the different chromatogram of various plants can be considered as characters of identification. the contents of oleanolic acid in 12 species of plants are determinated by hplc, but among the different plants and botanical organs their contents are different, and the highest content in flowers

  2. ( 3 ) firstly detectes the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slc ) of the epidermal cells in the leaves of 11 species, and studies the methodology, then give out two conclusion : a. epidermal cells in the place between middle and first side vein of the lamina on the third kont starting from ground have the most stable microscopic characters

    ( 3 )首次採用計算機圖像分析「 hpias ? 1000高清晰度彩色病理圖文分析系統」測定了獐牙菜屬11種藥用植物葉上表皮細胞垂周壁彎曲程度( sfc )和細胞縱橫直徑比( slf ) ,並進行了方法學研究,得到以下結論:莖上第3節葉片中段主脈與第一側脈之間上表皮細胞形態最穩定。
  3. Transitional feature of the arc and metal droplet in the welding process with steam shielded arc is investigated by means of analysing the waveforms of welding voltage and current under different welding regimes and it is found that there are two types of arc process behavor ? " arc starting - arc blowing out - short - circuiting " and " arc - starting - short - circuiting ". under the condition of constant diameter of welding wire and its feeding speed, the arc process behavor can be changed by adjusting the inductance of welding circuit as well as the voltage of power supply. if arc process behaves as alternative process of " arc starting - arc blowing out - short - circuiting " with minimum time duration of arc blowing out and maximum frequency of short - circuit transition, the welding process will be stable with less spatter and smooth weld bead

    通過分析不同焊接規范下的焊接電壓和電流的波形.研究了水蒸氣保護下電弧及熔滴過渡的特點,發現其電弧過程行為有「燃弧?熄弧?短路」和「燃弧?短路」兩種形式.在焊絲直徑和送絲速度一定的情況下,通過調節焊接迴路中的電感量和電源電壓,可以改變電弧的過程行為形式.若電弧過程呈「燃弧?熄弧?短路」交替進行,並且熄弧時間最短時,短路過渡頻率最高,在這種情況下,飛濺小,焊道成型好,焊接過程穩定
  4. The main results in this paper are as follows : ( 1 ) study on starting up performance of thermosyphon : according to the study on the states before and after starting up of thermosyphon with the various filling amount, it is considered that the phase change heat transfer inside the copper - water thermosyphon with a large ratio of length and diameter is not only influenced by the boiling degree of superheat, but also controlled by evaporation and companied with the boiling of the thin liquid film

    本文的主要研究結果為: ( 1 )熱虹吸管啟動性能的研究:通過對從不同充液量、啟動前狀態、內部汽化核心狀態對啟動的影響所進行的試驗研究,認為大長徑比的銅?水熱虹吸管管內相變不僅僅為沸騰,而是以蒸發為主,伴有薄液膜的沸騰。
