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。
There are many adaptive changes in the two research subjects ( artemisia. songarica schrenk. and seriphidium. santolinum ( schrenk ) polijak. ) in morphology and anatomy, such as with the increase of the daily age, the root - shoots ratio increased ; the root became stronger ; the ratio of leaf volume and leaf area increased ; the volume of epidermic cell decreased ; the cut - icle and phellem layer on the surface of root thickened. stoma caved in leaf ; epidermal hair of leaf and stem well - developed, palisde tissue developed well, the cell gap decreased ; the spongy tissue disappeared ; leaf is kinds of isolateralthat is the typical xeromorphic structure ; crystal cell and fibric cell increased ; conducting tissue and mechanical tissue developed well ; bundle sheath appeared
實驗研究的兩種菊科（ compositae ）植物（準噶爾沙蒿（ artemisiasongaricaschrenk ）和沙漠絹蒿（ seriphidiumsantolinum （ schrenk ） poljak . ） ） ，形態解剖方面的變化表現為：隨日齡增加，根長/株高比值日益增大；根系逐漸發達；體積與葉面積比逐漸增大；表皮細胞體積變小；角質層增厚；根外部出現加厚的木栓層；氣孔下陷；葉、莖部的表皮
毛密布，柵欄組織日益發達；而細胞間隙日漸變小；海綿組織逐漸消失；葉面結構常為典型旱生結構? ?等葉面；晶細胞及纖維細胞數目增多；輸導組織、機械組織日漸發達；具有維管束

Currently it is well established that each of the three parts of the hair follicle ( infundibulum, isthmus, and the inferior portion ) originates different types of cutaneous cysts thus, we can see several types of follicular cysts include infundibular cysts, trichilemmal cysts, and pilomatricoma

Using the calculation method of the tolerance value provided by lenat ( 1993 ), eighty - one tolerance values of macro - invertebrate taxa were acquired. among them, two genera in 2 families in coleoptera, 2 genera inl family in megaloptera, 14 genera in 7 families in ephemeroptera, 2 genera in 2 families in plecoptera, 6 genera in 5 familes in trichoptera, 1 geneus and 3 families in odonata, 12 genera and 3 sub - families in 3 families in diptera, 5 species in 2 genera in mollusca, 4 species in 1 genus in annipula and others 1 geneus
其中，依據lenat計算耐污值的方法，確定了81個分類單元的耐污值，包括
鞘翅目3科2屬，廣翅目1科2屬，蚌游目7科14屬，精翅目2科2屬，
毛翅目6科7屬，靖蜒目3科1屬， t翅目3科3亞科12屬，軟體動物2屬5種，環節動物1屬4種，扁形動物1屬。

The growth of the second follicle is vary by season. in autumn and winter, the speed of the growth of the second follicle is quick. in summer, that of the growth of the second follicle is slow. lt is same as the growth of cashmere. the weight of prolactin receptor is 87kd and 71 kd. the qualitity of prolactin receptor. is vary by season
