The possiblehost objective reason all is very many, but, our country numericalcontrol engine bed function part development backwardness -- varietyfew, unit technical level low, performance quality insufficientlystable, the cost stays at a high level, the delivery insufficientlywas prompt and so on -- not to be able to satisfy the numericalcontrol engine bed main engine product need to develop, had noalternative but to say was most direct, the most main reason, Becauseall numerical controls engine bed all is by each kind of function part(including host 轴头, straight line rolls guide rail, ball bearingguide screw vice-, numerical control tool rest, knife storehousemanipulator, rotary table, numerical control servosystem, surveyfeedback as well as safe protective equipment and so on), the functionpart which on foundation rack and so on the lathe bed, column thecollection attire becomes is the numerical control engine bedimportant component, moreover is the indispensable part.

可能主客观原因都是很多的，但是，我国数控机床功能部件的发展落后──品种少，单元技术水平低，性能质量不够稳定，成本居高不下，交货不够及时等──满足不了数控机床主机产品发展的需要，不能不说是最直接、最主要的原因，因为所有的数控机床都是由各种功能部件（包括主轴头、直线滚动导轨、滚珠丝杠副、数控刀架、刀库机械手、回转工作台、数控伺服系统、测量反馈以及安全防护装置等）在床身、立柱等基础机架上集装而成的，功能部件是数控机床的重要组成部份，而且是不可或缺的部份。

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

在诱导条件下，这些突变体表现出不同的形态和结构的变化，共有22个表型和结构发生变化。20个突变系发芽率或存活率较低，发芽率由10％—60％，其中2个突变系存活率分别为0％和50％。5个突变系在茎或下胚轴的结构上发生变化，其中一个突变系arris-stem发生如下表型变化：从真叶出现至开花结实的整个生长期，生长速度要明显比野生型拟南芥缓慢；叶缘有明显锯齿，莲座叶呈螺旋状排列；茎的基部有较多侧枝，侧枝间距明显缩短，茎有明显扭曲；突变体茎侧面有1至数条棱形突起，内部存在一至数个排列紧密的细胞团，由多层细胞呈环形排列，细胞壁明显加厚，内部存在管状分子，推测为维管组织。

This paper focuses on the performance improvement, it develops the controller of three axises and adjusts the control parameters in frequency-domain.

本论文针对转台的品质整定，基于频域法设计与实现了转台三轴的控制器，在频率域内整定了转台的动静态品质，并对整定过程中的问题和现象作了详细的分析和研究，提出了转台品质整定的关键点和注意点。

Gangliosides antagonized the apoptosis induced by corticosteron, and the underlying mechanism is related to activiation of neuronal calcium signal cascade, promoting neurotransmitter release. Gangliosides also have an ability to promote the neuronal filopodia formation and may have a antidepressive-like neuroprotecive effect. 2. Theory study: We explained the clinical symptoms showed in the syndromes of deficiency of kidney-Yang and deficiency of kidney-Yin with modern scientific technical terms. Moreover, we supposed the location of kidney of traditional Chinese medicine may be in the hippocampus but not in the hypothalamus, which is also the centre of learning and memory.

鹿茸有效成分能够拮抗皮质酮诱导的神经细胞凋亡，其机制与影响钙信号途径、促进神经递质释放有关，鹿茸有效成分还能促进神经细胞丝状伪足生长，并且可能具有抗抑郁药样的神经保护作用。2、理论研究：用现代科学语言对肾阳虚证和肾阴虚证临床症状的病理生理机制进行合理的解释，提出中医肾脑相关理论实质假说，推测补肾中药的调控点应当在下丘脑—垂体—肾上腺轴的高级中枢海马，而非下丘脑。

The relation between growth mode and atomic shift was established and the octahedra vibration was discussed in detail.

利用原子力显微镜，高分辨透射电镜等研究了这几种薄膜的生长模式、薄膜中的沿着c轴的原子层错和局域的氧八面体的无规扭曲以及它们之间的关系。

Designing the system schematic diagram explained the work principle of the hydraulic pressure synthesized test platform; According to the design of hydraulic pump, hydraulic valve, drill tubing choice and the computation, determined the model and the size of the hydraulic pressure part; In order to improving the consummation system, this article also carried on to test the system pressure loss and temperature increment; In addition, through the system calorific capacity computation, completed to choose the heater and the chiller ; Through designing the belt transmission and the axis structural, this article completed to the design of pumping station.
