That consider condyle, bone caruncle of 5 exemple, cartilage fibrosarcoma of 3 exemple, nerve fibroma of 1 exemple, nerve 1. The symptom after 27 patients operation all has different level improvement, live on average without tumour time is 33.5 months. Incontinent companion meets the patient relieve oneself of S1 of 5 operations reservation or above nerve root pubic feeling is lost, after manager cure function trains, 3 parts restore, 2 conserve without progress; bladder and rectum function obstacle all appear after the 12 patients art of root of S2 above nerve, after training via rehabilitation physiotherapy and function, 10 return to normal basically, 2 patients still are put in the obstacle of be convenient to both of different level. 10 withhold S3 or the patient of above nerve root can conserve constrictor function.

结果术后病理报告示：脊索瘤17例、骨巨细胞瘤5例、软骨肉瘤3例、神经纤维肉瘤1例、神经纤维瘤1例。27例患者手术后症状均有不同程度改善，平均无瘤生存时间为33.5月。5例手术保留S1或以上神经根的患者大小便失禁伴会阴部感觉丧失，经理疗功能练习后，3例部分恢复，2例无进展；保全S2以上神经根的12例患者术后均出现膀胱及直肠功能障碍，经康复理疗和功能练习后，10例基本恢复正常，2例患者仍存在不同程度的两便障碍。10例保留S3或以上神经根的患者能保全括约肌功能。

In the broad-leaved Korean pine climax forest, the fine root climax production of the community occurs in July and October, but the dominant arboreal species, understory arboreal species and fine roots of grass have a different production dynamics. It is important to sort the fine root species because accurate fine root production sources have a different fine root dynamics.

在原始阔叶红松林中，群落细根的生长高峰发生在7月和10月，但其中主要树种、其他木本和草本的细根有着不同的生长动态，所以在计算细根生产量时应该分类计算，才会得出较为准确的结果。

In this paper, the author proves that the generalized Newton's method for finding me roots of an algebraic equation converges to the root, real or complex , nearest to the starting point. A tabulation method is then devised and used in four illustrative examples.

在本文内，作者首先证明了求代数方程根的推广牛顿法收敛于离出发点最近的一个根，其次设计了一种简单的列表计算法，最后通过四个例题说明用这种方法可以逐步接近代数方程的实根或复根。

The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

给药局部肉眼观察未见明显的纤维组织增生；HE染色可见B、C、D三组给药后四周及八周时硬膜内外均有炎细胞浸润，纤维细胞轻度增生，硬膜外神经根内有炎细胞浸润及炎性渗出；特殊染色B、C、D三组同A组相比未见有脊髓及神经根的改变；免疫组化染色，给药后四周及八周时，硬膜内外均有Ⅱ型胶原纤维增生；固兰染色B、C、D三组未见有明显脱髓鞘改变，与A组相比无明显异常改变；电镜观察B、C、D三组在给药后的四周及八周时，表现为硬膜外神经根内髓鞘厚薄不一，形状不规则，可见成纤维细胞，神经内膜中可见有巨噬细胞；粗大的有髓神经纤维变化明显，无髓神经纤维受累较轻；八周时电镜下D组改变较B、C两组为轻。

The secondary phloem is larger than the secondary xylem in the Heracleum , which is the typical storing root .

根据独活属植物根的次生韧皮部远比次生木质部发达的特点，确定独活属植物的根是典型的贮藏型根。

The result suggests that there be no correlation between the expression of cyc07 and enhanced elongation of rice seminal root under upland condition.

本研究克隆了细胞分裂S期特异基因cyc07，将其定位在第1染色体，同时对其在淹水与旱种条件下水稻根尖中的表达进行了分析，发现cyc07在两种培养条件下的根尖中的表达没有差异，cyc07可能与旱种条件下水稻种子根的伸长无关。

Histochemical assays of GUS gene showed those resistant callus and roots from transgenic plants cultured under light were no blue-stained with X-gluc, but callus and roots after 24 h treatment of darknees and then incubated with X-gluc could present blue. Fluorimetric enzyme quantitative analyses indicated GUS expression in transgenic plants was organ specificity.

转基因抗性愈伤和转基因植株根的组织化学GUS活性检测表明，光照培养下的抗性愈伤和转基因植株根不能使X-gluc显色，而暗处理24 h后的抗性愈伤和定植后转基因植株的根能使X-gluc显色。

When cultured on the medium with different auxin , root segments could elongate and branch, and the addition of 1mg/l IBA into the medium was the most suitable for long-term root culture. Calli could be induced from root explants in the presence of 2, 4-D and when transferred onto E medium, they transformed further into embryonic calli which could develop into normal plants through the stages of globular-embryo, heart-shaped embryo, torpedo-shaped embryo, cotyledonary embryo.

培养基中添加生长激素（IAA，IBA，NAA）能够诱导无菌苗根切段的生长和分枝形成；而1mg／l IBA的存在，最适合于根的长期离体培养。2，4-D的存在能够诱导根外植体脱分化形成愈伤组织，愈伤组织转移至E型分化培养基能够转变成胚性愈伤组织，并进一步经球形胚、心形胚、鱼雷形胚、子叶形胚发育成正常植株。

The other component had a wide distribution range and smaller kurtosis. Root longevity, analyzed by growing-season cohort, was characterized by each of the four theoretical probability distributions: Normal, Welibull, Lognormal, and Exponential.

第一组分的分布峰度较高，寿命较小，且细根均在一个生长季死亡，是细根的主要组成部分；第二个组分的峰度较低，分布平缓，寿命分布范围较大，且细根在两个生长季死亡。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
