The complete wind turbine speed control firstly proposed here also improves the tracking effect of wind turbine rotating speed to variable wind speed. Wind turbine rotating speed synchronized power observer compensates the power ripple of wind turbine resulted in inverter dead time. A low pass filter used at the output of MPPT controller smoothes the speed reference, which makes the rotating speed of wind turbine more stable.

本文首次提出的变转速扰动的MPPT控制提高了风车最大功率点追踪的快速性和稳定性，风车完全转速控制提高了风车转速对变动风速的跟踪效果，转速同步风车功率观测法消除了逆变器死区所造成的风车功率波动的影响，带有低通滤波器的MPPT控制器使得风车的转速更加趋于平稳。

1The soil water c haracteristic curves of four soil layers in this soil were consistent. The satur ated water content, field capacity, wilting coefficient and available water capa city decreased from top soil to bottom in soil profile.(2)The unsaturated hydra ulic conductivity was significant relation with the negative pressure head in ex ponential function and tended to stable when the negative...

土壤的饱和含水量、田间持水量、凋萎系数和土壤有效水的含量均从土壤上层到下层呈降低的趋势；土壤的非饱和导水率与负压水头之间呈负相关的指数曲线变化，当负压水头达到 10 k Pa时，非饱和导水率降低到最小值，且基本趋于稳定；非饱和土壤水扩散率变化于 1.1× 10 - 3～ 1.886× 10 - 3cm2 / min之间，非饱和土壤水扩散率随含水量也呈指数曲线变化。

Academician Xi's study on the history of Chinese scientific thought, his unscrambling of the Needham Puzzle, and his criticizing of Emperor Kangxi's science and technology policy, are finally observed, and it is pointed out that Academician Xi, the author of the Self-selected Works, should be taken as a real scholar, who will never be academically conservative along with his accumulation of academic achievements, his increased academic reputation, as well as his age growth.

最后评述了席泽宗对中国古代科学思想史的研究、对&李约瑟难题&的解读和对康熙科技政策的批评，认为席泽宗不因为学术成果的积累、学术名望的上升和年龄的增长而在学术上趋于保守，体现了一位真正学者的大家风范。

It's application advances efficiency and quality of work which is the manage system of personnel labor wage,and the work becomes standardization.

该系统的推广应用，大大提高了劳动人事工资管理的工作效率和工作质量，使劳动人事工资管理工作趋于规范化和标准化。

Firstly, according to study dynamic changes of the elements structures in succession about natural and artificial forest, then summarized regular patterns;at the same time.based on the study of Coupling Relationship between structure and function of water conservation forest established the ideal structures from the stand level and the watershed level. The ideal structures from the stand level: uneven-aged, double layer and mixed structure, and trend to natural forest. The watershed level followed the same principle, that is double layer patches, uneven-aged forest well-distributed and to build up different forest patches in watershed.

首先，经过对北京山区水源林天然林和人工林结构要素的演替动态研究，提出其发展规律，同时依据水源林结构与功能耦合关系研究，从林分层次和流域层次上分别构建了水源林的理想结构，其中，林分层次上水源林的理想结构为：异龄、复层、混交的结构状态，林分结构趋于天然林结构的特征；在流域层次上水源林的理想结构为也应形成&复层&、&异龄&、&混交&的结构，即：在流域各水源林斑块间形成林冠层复层、斑块内部乔木、灌木、草本层的复层；不同水源林年龄面积上的均匀分布；形成不同水源林斑块间的镶嵌分布。

Results The articular cartilage constructed by the technique of centrifuge tube culture was hyaline cartilage.

结果在体外培养第2周时，组织切片可见软骨样组织结构；第3周时软骨发育趋于成熟，经阿新蓝染色基质丰富；第16周时，组织形态无明显变化，未见钙化。

The temperature range of phase transformation from γ-Fe to α-Fe is 300-550℃: the activity of carbon atoms in solid solution of α-Fe would be increased with increasing the annealed temperature, and the diffusion of carbon atoms results in analogue state of different Fe configurations.

Fe相向α-Fe相转变的温度范围为300-550℃；α-Fe固溶体中的C原子的活度随退火温度的提高而提高，C原子的扩散导致不同的Fe原子组态趋于一致。
