The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

结果表明：水培后根冠不明显，淀粉体较少，多糖类物质较少而土培根根冠体积较大，淀粉体较多，多糖类物质多，土培根PAS反应强烈；水培根表皮厚度比土培根小，水培根根毛少或退化消失；水培根皮层薄壁组织发达，细胞大型，壁薄，细胞间隙中含有溶生性通气组织，土培根皮层未见通气组织。

The study is carried out that the comparison of fine root production, decomposition and distribution along with Korean pine and broad-leaved climax forest succession; the fine root contribution to the belowground C and N storage along with Korean pine and broad-leaved climax forest succession; and the comparison of belowground C and N storage among the Korean pine and broad-leaved climax forest, three dark-conifer forests, a betula ermanii forest along altitude.

Especially, the number of type Ⅰ complex terminals which come from unmyelinated afferent fibers recovered to the level of unoperated side. It indicates that morphine may promote the collateral sprouting and synaptic reinnervation of primary afferent fiber, unmyelinated afferent in particular. 4. Although the collateral sprouting and synaptic reinnervation were shown also in spinal cord of operated side in 34 days spared root rats, they were slower than that of morphine spared root group.

表明吗啡促进了备用根初级传入纤维，特别是无髓纤维更快地向L〓脊髓段侧支出芽，稍后在L〓平面脊髓内侧支出芽以及突触重建。4、34天备用根大鼠术侧脊髓内也有侧支出芽和突触重建，不过侧支出芽的速度要比吗啡组慢。5、电镜定量结果也显示，吗啡备用根大鼠和备用根大鼠术侧备用根的无髓纤维数比备用根大鼠非手术侧的分别增多60％和42％。

Results Preserving bilateral S1 anterior and posterior roots intact combined with rhizotomies of L7 and S2～3 posterior roots, intradural stimulation of S1 posterior root producedan increase of bladder and urethral pressure similar to that of stimulation of the S1 common root in extradural.

结果 保留2侧S1前后根完整，电刺激同平面S1的总根或后根，膀胱尿道的压力反应相同；切断两侧S1前根，刺激同平面的S1后根，膀胱尿道的压力反应显著降低，仅为前后根完整时的7%～12%。

The morphemic order and the degree of fusion are not arbitrary, in that the categories that most affect the meanings of the stems occur closest to the stem, whereas those that have least impact on the lexical meaning of the stem occur in the periphery.

此项假设认为构词法中语素和语素之间的结合方式、先后次序和远近关系是任意的﹕凡是影响语根之语意变化最直接、最全面的语意范畴，在距上一定最接近语根，相反的，影响语根之词汇语意变化最小的语意范畴则远语根，所以衍生词缀距语根较近，而屈折词缀距语根较远。

A group: to measure the length of root canal by Root ZX, prepare the root canal and test the trial point for a best position of the major Gutta Percha Point in root canal obturation with lateral compaction, then take X-ray photos.

随机选择需行根管治疗术的单根管恒前牙、双尖牙 2 30颗，分为A、B两组，A组采用RootZX 根管测量仪测量根管长度，根管预备后，根管充填时加试尖步骤，调试出最适主尖后侧压充填根管，摄牙片

During storage, the reducing sugar content of chicory root increased rapidly then decreased guadually, non-reducing sugar content and protein content decreased gradually.

-2℃条件下贮藏的菊苣根中还原糖的含量在整个贮藏期间高于0℃条件下贮藏的菊苣根，而非还原糖的含量则低于0℃条件下贮藏的菊苣根，总糖在菊苣根的鲜重中的含量是0℃条件下贮藏的菊苣根高于-2℃条件下贮藏的菊苣根，总糖在两个贮藏温度下菊苣根的干重中的含量则是几乎相等。

The leaf WUE of millet was increased when root cutting in seedling stage,and only the treatment of I2D of maize increased the leaf WUE; The biomass WUE of millet and maize were increased excepting the root cutting treatments of "TM" and "sl"; At the 80% field capacity, when the root was cutted more seriously and more later,the seed yield WUE of millet were dropped; While at the 50% field capacity, the seed yield WUE of millet was increased when the root cutting is moderate in prophase,and have no reduction of output or increase the production at the same time ,while the benefit of saving water didnt evidently at the later stage root cutting.

苗期伤根处理能够提高谷子叶片WUE，而玉米伤根后仅I2D处理的单叶WUE高于对照；除TM和sl处理外，伤根处理提高了谷子和玉米生物量WUE；在土壤含水量为80%田间持水量时，随着伤根程度的加剧和伤根时间的后移，谷子子粒产量WUE下降，伤根不利于谷子WUE的提高；而在50%田间持水量时，前期伤根量适度的处理在不减产甚至增产的情况下还有助于作物子粒产量WUE的提高，而后期伤根的节水效果并不明显。

The shoot formation rate of IBA induced PLBs was high, no matter they were cultured on yam bean or potato homogenate containing media. The 1/4 diluted MS basal salt medium had the best root induction and growth rate. Root cutting affected plantlet height and the number of shoot. However it had no significant influence on root length and number of root.

发根试验中探讨培养基中MS基本盐浓及继代培养时进根处对小苗发根生长之影响，结果显示含有1/4MS基本盐浓之培养基发根最高，而继代时之根处，会影响组培苗地上部之苗长及定芽，但对地下部之根长及根影响并显著。
