We have observed the following characteristics of anatomical structure and development : ( 1 ) the primary roots belong to archetype and the lateral roots occur in the position toward the xylem of the vascular cylinder ; ( 2 ) the root endodermis consists of thicken casparian strips, and there are from two lo four layers parenchyma cells near the pericycle ; ( 3 ) the pith and resins canals are absent in the toots ; ( 4 ) secondary structure occurs in the root hair zone, and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem ; ( 5 ) tanning materials are abundant in pericycle cells and phelloderm cells ; ( 6 ) sclereids are found in secondary phloem, and rays are rather rich in secondary xylem
結果表明：氣生不定根具有以下結構特徵和發育特點： （ 1 ）根為二原型，側根正對著木質部發生； （ 2 ）幼根內皮層細胞具凱氏帶加厚，維管柱內緊挨中柱鞘內側具有2 ~ 4層大型薄壁細胞； （ 2 ）根中無髓和樹脂道； （ 4 ）次生結構發生於根毛區，維管形成層由初生木質部和初生韌皮部之間的薄壁細胞轉化形成； （ 5 ）中柱鞘和栓內層細胞富含單寧類物質； （ 6 ）次生韌皮部有石細胞，次生木質部射線發達。The carbonate content varied from 0 to 34. 55 % in the column of drilling core ey02 - 2, the higher carbonate content related to materials of modern and old yellow river in postglacial period, while the peak carbonate content related to the shell fragment in the sediment, the dissolved cycle appeared to be the carbonate dissolved cycle of the atlantic mode
Ey02 - 2孔柱樣碳酸鹽含量在0 - 34 . 55之間變化，呈現大西洋型caco _ 3溶解旋迴，冰後期以來碳酸鹽高含量與高碳酸鹽的現代黃河和廢黃河物質有關，而中晚更新世碳酸鹽極高含量與貝殼含量有關。By using ec membrane material as column packing, double - distilled water as mobile phase, the retention times ( tr " ) are measured with suitable inorganic and organic compound as solutes. 3. complying with the retention times, the partition coefficient of the solute ( ka " ) and the ratio of the surface excess concentration of solute ( ) with the concentration of the parent fraction ( cab ) are calculated
利用物理改性的方法研製了乙基纖維素（ ethylcellulose ，簡稱ec ）膜材料，並將其作為高效液相色譜柱的固體填料，以高效液相色譜模擬反滲透實驗平衡條件，以水為流動相，選擇合適的無機物和有機物作為溶質，測定乙基纖維素對它們的相對保留時間及平衡分配常數k _ a 。The element content in the fine - grained fraction ( < 0. 063mm ) of the core is great. the correlation coefficient between the elements in the coarse - grained is high, which indicate that the coarse - grained sediments derived from the same provenance
柱樣中細粒級（ 0 . 063mm ）元素含量較粗粒級（ 0 . 063mm ）高，變化幅度大，從元素之間相關性來看，粗粒級的元素之間相關系數高，表明粗粒級物質具有統一來源。分享友人
