The second part give an all-around demonstration on eco-economic backgrounds of hilly gullied loess region and concluded that small watersheds are dominant landscape units that enable them to be basic for regional management and development.

第二部分综合阐述了黄土高原丘陵沟壑区的生态经济背景，指出：小流域为黄土丘陵沟壑区的优势景观单元，是区域治理与发展的基本单元；并提出区域治理与开发的生态与生产定位：区域应以水土保持、改善生态环境为新世纪的主要战略任务，国家的退耕还林草政策为区域加大环境治理提供了新的契机；在生态环境明显改善的基础上实现粮食自给，实行农牧结合，重点发展畜牧业，有选择的发展经济林果业。

The second part give an all-around demonstration on eco-economic backgrounds of hilly gullied loess region and concluded that small watersheds are dominant landscape units that enable them to be basic for regional management and development. Ecological and economic strategies for regional development are also put forward: soil and water conservation to improve ecological environment should be first-line task the region shoulders in the new century."Grain for Green"policy provides chances of accelerating development for the region. Maintaining food self-supporting based on an improved ecological environment; combining agriculture and husbandry in the production system; taking husbandry as pivot while selectively develop cash forest.

The bamboo was spread out and hackled into bundles after different pretreatments.The rupture strength and fineness of the bamboo bundles were measured.

竹束是竹材(包括竹秆、竹筒、竹片和竹篾等)通过碾压或锤击梳解成通长的、相互交联并保持纤维原有排列方式的梳松束状单元，可作为重组竹或木竹重组材的构成单元[1]。

Based on the structure cell model, this paper idealizes the cuboid cel1 as the reinforced musc1e cel1 that includes a isotropi c elast ic matrix material and di fferent oriented fiber material that has sing1e axia1 stiffness.

根据结构单胞模型，将长方体单胞理想化为加强筋单元，即由一个各向同性弹性基体材料长方体和不同取向具有单轴刚度的纤维单元叠加而成。

The performance effects and jamming mechanisms of CCD, IR detector and tracking system are researched in detail when laser irradiates them. Based on the composing and working principle of CCD and IR detector, the photo-electricity characteristic of them are studied and the saturation effects of them induced by laser are also analyzed.

从CCD 及红外单元探测器的基本组成及工作原理出发，研究了二者的光电特性，分析了激光辐照CCD 及红外单元探测器件的光学饱和效应以及视场外激光对CCD 的干扰中所需要考虑的两种光学效应及干扰机理，并开展了脉冲、连续YAG 激光对KA-320 型CCD 的辐照实验。

When microgrid is operated in islanded mode, VSGs can be divided into non-frequency regulation units and frequency regulation units, the former can generate power and participates in primary frequency control according to dispatching to mitigate system frequency deviation due to disturbances; the latter can offer referential voltage of microgrid and use secondary frequency regulation to implement no-error frequency control.

微电网孤岛运行时，将虚拟同步发电机分为非调频发电单元和调频发电单元，前者既能按照功率调度指令发电，又能参与一次调频，缓解扰动情况下系统频率的波动，后者提供微电网参考电压，并利用二次调频实现频率的无差控制。

On the other hand,the author chose several characteristic buildings to expose and analyze the composing and space features of their architecture unit .It concludes the leading factors of the hamlet space shapes in different aspects and summarizes how these individual building joggled and extended to a whole.Besides,it discussed the relationship between the law in the microcosmic architecture organization and macroscopic hamlet network shapes.The paper is analysing based on monomer and groups which belong to the external space of the traditional villages.Because the external space is not only a single element,but the organic components of the external space.

论文同时还选择了黄田古村落的几处特色的建筑，对其从建筑单元到建筑群的组合构成和空间特点进行了阐述和分析；总结了影响村落不同层面空间形态的主导因素；概括了建筑单元平面和界面的模式化特点在村落的四个空间层面中的表现；解析了建筑如何逐渐拼合扩展为村落的整体；揭示了微观的建筑组织规律与宏观的村落网络形态的关系。
