2 comparative study on morphology in the light of the form of the materials, hup shows more approximate relationship with gri : they are 50 ~ 70cm high at the period of fructescence ; both are perennials and reproduce themselves by root stock, and especially, hup can also reproduce itself by branch roots and buds growing from stipes when the stems fall againt the ground, and then those buds develop into new bodies ; while gri can reproduce itself not only by vegetative propagation but by seeds. both of hup and gri characterize with bigger leaf blade and with the approximate form of simple leaf, with root stock, and with two - line seeds in one fruit
2形態學比較從形態上來看，新種hup與分佈海拔高度相近的gri比較接近:植株體高大，果期株高50一7ocm ;都為多年生，能以其根狀莖繁殖，但前者還以較為特殊的營養體繁殖後代，即倒伏后每個莖節上長出新的根和芽，發育成獨立的新植株，後者既能以營養體繁殖，又可通過種子繁殖;具有較大的葉片且單葉形態相近，果實內有二行種子（其它種為一行） . 。 -
Test results indicated : with the hoist of altitude, the increase of ice amount and the rise of pollutant, the average flashover voltage reduced. the character exponent generally depends on the insulator profile, ice amount, ice state and pollution severity etc. by means of a high - speed camera, a data acquisition system and high voltage test facilities, a series of the flashover processes on ice surfaces were record. the experimental results form this study and the subsequent theoretical analyses suggested : the thermal ionization of the air in front of an arc root resulted in arc movement ; the electrostatic force had an auxiliary effect of impelling arc propagation ; the electrical
通過對攝像機、數據採集系統及高壓試驗裝置記錄覆冰絕緣子表面閃絡電弧的發展過程的試驗結果進行理論分析得出：弧根周圍空氣的熱電離導致了電弧的發展，靜電場力對電弧的發展起到了加速作用，電擊穿僅發生在閃絡最終的跳躍階段；通過測量閃絡過程中的放電電壓、泄漏電流、閃絡時間、覆冰水電導率、電弧長度及電弧半徑等參數，得到了不同階段電弧（電弧起弧階段、電弧發展階段及完全閃絡）的發展速度、臨界電弧長度均隨覆冰水電導率的增加而減小。 -
The network carbide and acicular martensites that existed in the microstructure of the root grooves of the spline due to improper carburating and quenching process of the shafts, led to the initiation and propagation of the intergranular microcracks and were the main reason that caused the early fracture of the shafts
由於滲碳淬火工藝不當，在二軸花鍵槽根部的組織中產生了網狀破化物和粗大的針狀馬氏體，在外力作用下形成沿晶顯微裂紋並擴展，是導致二軸疲勞斷裂的主要原因。 -
When the resource was rich in habitation, the ability of clonal propagation was significantly increased. and ratio of development root reached to 100 %. thus, certain ramets were reproduced
當資源豐富時，克隆繁殖能力明顯增強，當年成根率達100 ，也能形成一定量的分株。
