These results revealed that the pollen chamber developmental pattern passed through four phases. Firstly, a group of nucellar cells at the micropylar end elongated longitudinally. Thereafter, the uppermost nucellar cells at the micropylar end initiated PCD; and these elongated cells undergoed PCD in a basally and laterally oriented direction to form a cavity.

贮粉室的形态发生可分为4个阶段：最先是位于珠孔端的几层珠心细胞纵向地伸长；接着，珠孔端最顶部的珠心细胞发生PCD；然后，那些已经纵向伸长的珠心细胞向基地和侧向地依次发生死亡，产生贮粉室空腔；最后，珠孔端的珠心表皮细胞发生开裂，形成贮粉室的开口。

The characteristic in liquid culture of the purified strains were described, and the relation between the characteristic and the taxonomic traits was researched for the first time. The two groups of Myxobacteria differentiated according to the shape character of the myxospores and vegetative cells had different characteristic in liquid culture.

对纯化菌株的液体培养特征进行了描述，并首次依据初步分类鉴定结果探索了液体特征与分类地位之间的关系，即依据营养细胞和粘孢子形态将粘细菌划分成的两大类型中，第一类型(包括粘球菌属等7个属)的菌株在液体培养基中通常形成片状或絮状，而第二类型(包括单囊菌属等5个属)的菌株则主要呈现球形。

Methods At first, retrovirus vectors encoding IFN-γ or IL-4 gene were constructed. They were transfected into PA317 packaging cells by lipofectamine, PA317IFN-γ and PA317IL-4 cells were obtained. C6 glioma cells were infected with replication deficiency retrovius containing IFN-γ or IL-4 gene, cell morphology、cell growth curve and cloning efficiency assay were examined. The intracranial C6 glioma animal model was established in immunocompetent Wistar rats. PA317IFN-γ and PA317IL-4 cells were stereotactically implanted into the tumor areas alone or together. The survival of tumor bearing rats were examined, tumor volumes were measured and immunohistochemical analyses of CD4〓 and CD8〓 T lymphocyte infiltration were performed.

构建和鉴定携带IL-4或IFN-γ基因的逆转录病毒载体，将其导入逆转录病毒包装细胞PA317，通过G418抗性筛选，得到携带目的基因的包装细胞并鉴定；应用携带IL-4或IFN-γ基因的复制缺陷型逆转录病毒感染C6胶质瘤细胞，观察对C6胶质瘤细胞形态、细胞生长曲线和克隆形成率的影响；建立C6胶质瘤大鼠脑内移植动物模型，将携带IL-4和IFN-γ基因的逆转录病毒包装细胞分别或联合注射到脑内荷瘤大鼠的肿瘤组织中，观察其治疗作用，并初步探讨其机制。

Influence of deposing condition on the grain size, crystal structure and surface properties of nano-TiO_2 was investigated; the existing position and action of TiO_2 in oil/water system was also studied. Results of photographs show that nano-TiO_2 can enter the oil/water interface and well dispersed, a solid film is formed and well stability.

3采用溶胶-凝胶法及掺杂调制技术制备了纳米TiO_2光催化剂，考察不同的热处理条件对二氧化钛(TiO_2)纳米粒子的晶粒尺寸、晶体结构、表面性质的影响，并研究了纳米TiO_2在油／水体系中的形态与存在形式，显微图像观察结果表明，TiO_2纳米粉可以进入油／水界面，在油／水体系中具有较好的分散性能和界面性质，形成一层固体膜，并且具有很强的稳定性。

The three functional sections in the space are separated by the flowing interspaces in between, together with the smooth ground form an integrated space, or to say an amusement park.

设计方案充分考虑到这三个实体之间的虚空间的尺度、形态，加上没有一处直角的弧形墙面和贯穿于其中不同高差的地面地台，形成了一个优美的流动空间，一个让人穿行其中游戏场所。

When the underground water percolates through a soluble rock sequence along its fissure it will dissolve large amount of calcium carbonates and seep out from the sidewalls and the roof. Due to the changes in temperature and pressure, water evaporated and carbon dioxide escaped and the dissolved calcium carbonate in the water precipitated in various forms.

地下水沿着可溶性岩石和裂隙渗透，溶解了岩石中的较多的碳酸钙，通过洞顶或洞壁滴流出来，因为温度、压力的改变，水的蒸发，二氧化碳散失，使溶解在水中的碳酸钙沉淀下来形成各种形态。

Included among them are: characteristic frequency curve of reinforced medium; critical length of the anchor bar ; anchor bar density and nonuniform coefficient of the reinforced medium; embedded anchorage layer effect; bed plate effect; weak surface effect; distortion of the bow-shaped distributed state of the anchor bar frictional resistance and initiation, formation and development of the dominant glide control plane; criteria about the displacement velocity of side-wall stability status, critical status and unstability status, and the system of ordinate analysis method, et al

d。文中提出的若干新的概念、判据和分析方法，如加固介质特征频度线；临界锚杆长度；锚杆密度及加固介质不均匀系数；嵌固层效应；垫板效应；弱面效应；锚杆&弓形&受力形态的畸变与优势滑移控制面的产生、形成和发展；边壁稳定状态、临界状态和失稳状态的位移速度判据；纵坐标系分析法等，具有一定的理论价值，并对软土工程围护设计具有指导意义。

The article thinks, the rapid development of Chinese auto industry, need strong other people to shed support, and content of our country car sheds course of study to develop relatively lag, the car produces manufacturer content to shed cost house not to fall high, configuration of content shedding service is primary, progress of job of content shedding standardization is slow, effective price system had be notted form, the development that these are the commercial vehicle of local; China that need improves will promote the development that highway content sorts greatly, change in business affairs of globalization, electron, the client is custom-built change, flexible change, change subtly wait for a respect to flow to car content pose bigger challenge.

文章认为，中国汽车工业的快速发展，需要强有力的物流支持，而我国汽车物流业发展较为滞后，汽车生产厂家物流成本居高不下，物流服务形态初级，物流标准化工作进展缓慢，有效价格体系尚未形成，这些都是需要改进的地方；中国商用车的发展将极大地促进公路物流的发展，并在全球化、电子商务化、顾客定制化、柔性化、精细化等方面对汽车物流提出更大的挑战。
