Myconrrhizal fungus infected the cortical cells and formed pelotons in the cells, after it penetrated the exodermal passage cells through velamen cells. It is interesting that strain AR-18 also penetrated exodermis from the cortical cell next to it, where mycelium grew vigorously and infected inner cortical cell, even a few mycelium penetrated endodermis while there was no mycelium in the fibrovascular bundles.

真菌AR-15与金钗石斛一起培养时，真菌菌丝与根被细胞密切接触并侵入根被细胞，也可通过侵入根毛进入根被细胞，由根被继续侵入外皮层通道细胞，进一步向皮层细胞侵染；部分根被真菌危害，根部组织内有大量真菌孢子和菌丝。

Strain AR-15 penetrated the exodermal passage cells through the velamen cells or root hairs and further infected the cortical cells. There were a number of spores and hyphae in plant roots that was damaged by strain AR-15. Study on the ultrastructure of D. nobile root and its endomycorrhizal formationshowed that the wall of velamen cells of D. nobile root was thin, and there were waxylayers outside of velamen. Cells of exodermis were arranged tidily, having thick wallsand chloroplast.

金钗石斛根及其菌根的超微结构研究表明，金钗石斛根的根被细胞薄壁，在最外层根被细胞之外覆盖着蜡质层，外皮层细胞排列整齐，细胞壁厚，内含叶绿体，靠近外皮层的皮层细胞含叶绿体、线粒体，皮层细胞壁薄，细胞核明显，周围有叶绿体围绕，细胞膜附近有小泡结构。

Root hair was not present on the roots of this plant. Root of D.candidum possesses the typical root structure of orchids including velamen, exodermis,thick cortical tissue, endodermis, pericycle, vascular bundle and pith. Strain AR-18grew toward D.

真菌AR-18倾向于根生长，真菌在根周围形成了一个包围圈，并侵入根被细胞，由根被继续侵入外皮层通道细胞，进一步向皮层细胞侵染，在皮层细胞内形成菌丝结，从而形成内生菌根。

Six cadavers were prepared for necroscopy, operative procedure of ILIF were simulated on L3-S1, and all related important anatomic structure and their relationship were observed and record. ILIF with transpedicle screw fixation were also performed with cage insertion.3. Twelve fresh frozen bovine lumbar functional spinal units were prepared for biomechanical testing. According to the different treatment order, the specimens were devided into 7 groups, which included: 1intact specimens, 2specimens were treated by left unilateral facetectomy and had homolateral anatomical threaded cages inserted, 3 TLIF with homolateral pedicle screw fixation, 4 TLIF with bilateral pedicle screw fixation, 5 specimens had anatomical threaded cages inserted on the left by intertransverse process approach, 6 ILIF with homolateral pedicle screw fixation, 7 ILIF with bilateral pedicle screw fixation.

方法1、对20名正常志愿者L3-S1节段进行CT增强+三维重建检查，在三维重建图形上测量横突长度、上下横突间距、椎间孔外椎间隙高度及斜径，观查横突间区域血管走形特点并测量血管内径，然后进行统计分析及评价。2、采用福尔马林固定尸体标本六具，模拟ILIF手术对L3-S1节段进行操作，观察横突间区域重要结构的位置和毗邻关系，并模拟同侧椎弓根钉和单枚椎间融合器的置入过程，探讨该术式存在的问题并改进。3、采用小牛脊柱运动节段标本12具，依序进行不同处理后分为以下7组：⑴正常对照组CG⑵左侧小关节切除+椎间融合器植入组(TLIF⑶TLIF附加同侧椎弓根钉固定组；⑷TLIF附加双侧椎弓根钉固定组；⑸左侧横突间入路椎间融合器植入组ILIF⑹ILIF附加同侧椎弓根钉固定组；⑺ILIF附加双侧椎弓根钉固定组。

In all, the thesis obtains the following two objects: First of all, the points of view that people have discussed are excluded. Moreover, the thesis concentrates on adding Bacon"s thoughts that people haven"t emphasized, and corrects the mistakes that people have made concerning Novum Organum. At the same time, the thesis evaluates the viewpoints of Bacon and Novum Organum from historical and dialectic angles. Second, combining the contemporary scientific ideology, the thesis concludes that the viewpoints of Novum Organum are great inspirations to the Modern science. In all, this thesis reviews the philosophical and scientific viewpoints of Bacons Novum Organum on the basis of analyzing the materials of Bacon and Novum Organum. The thesis is divided into four parts.

所以，本文欲采用史学研究与哲学分析相结合的方法对前人的见解和培根及其《新工具》本身进行系统的探讨，希望能达到以下两大目的：首先，对《新工具》中前人已着重论述过的思想不再涉猎，致力于补充培根其他哲学和科学思想的研究资料，并剔除对培根思想的一些误读，同时把对培根的评价放入历史的长河中进行具体研究，用辩证的眼光看培根在那个特定时代下所做出的贡献；其次，在对《新工具》中的思想进行研究时，时刻结合当今现实和当代科学思维成果，古为今用，洋为中用，发掘《新工具》对今天的启示。

Mycorrhizal spores in most rhizospheric soil of weed species, except Vida cracca, TrfoHum npens and Oxalis cornculata, decreased significantly. 2 Influence of coexisting of various plant species on AMF colonization in Pb polluted soil Comparing with monoculture,the results showed mat diversity did not affect on die AMF colonization of weed plants planted in soil at the concentration (334.5251mg/kgsoil or nonpolluted soilsignificandy.In the experiment of species combination with Trfolium repens, Lolium perenne, Poa annua, Plan tago virginica, the infection rate of all species increased in Pb treatment except Poa annua, implying that diversified plant species coexistence may alleviate the impacts of Pb on mycorrhizal colonization.

铅污染土壤条件下不同植物物种互作对菌根的影响通过盆栽加铅模拟试验，在铅污染(334.5251mg／kg土)的土壤中，黑麦草、早熟禾、白车轴草和北美车前无论是对照还是铅处理，多植物物种共存组合中的杂草菌根侵染率与单个物种相差不大，AMF菌根侵染率的处理间差异的变化趋势在铅污染的土壤和对照土壤条件下表现一致，但铅处理与对照相比，除了早熟禾外，菌根侵染率均升高，说明杂草多样性对菌根有一定的保护作用。
