We have completed the earlier stage research on theory analysis, fabricated the GRIN sphere lenses using two kind of monomer selected by suspension diffusion copolymerization method, measured their refractive index distribution curve and other optical parameters of them, and evaluated imaging quality on the basis of their distribution curve.

本工作对此种透镜的光学性能进行理论分析，选择两种适当聚合物单体利用悬浮扩散共聚的方法加工制备此类微球透镜，测量所得透镜的折射率分布曲线和其它光学参数，并对此种梯度折射率微球透镜的成像特性进行了评价。

First the new total losses calculation method is implemented by means of the classification of variable loss and invariable loss. Hereby, the optimal voltage curve corresponding to the minimum total losses could be conveniently obtained according to the given torque curve. Then the calculation and implementing method for optimal voltage under every running condition are put forward by use of on-line measured field input quantities.

按照不变损耗和可变损耗新的划分方式得到相应的损耗计算方法；据此，根据给定的转矩曲线，能方便地得到总损耗最小所对应的最优电压曲线，进而提出由现场在线可测输入量求得各种工况下最优电压的方法。

Hydrostatic transmission is widely used in construction machine. The research of one of its hard cores, low speed high torque radial piston motor, is very important. To directly estimate the life of this kind of motor, and to design a orbit curve with the longest life at same condition, this paper gives theoretic research of the equal contact stress inner curve of radial piston motor. The research is divided into four parts:1 Taken all forces the piston endured into consideration when radial piston motor working, the force between roller and orbit is deduced.

静压传动技术在各类工程机械中得到广泛的应用，对作为其核心部件的径向柱塞式低速大扭矩液压马达的研究显得十分重要，为了能直接对这种马达进行寿命估计，并能在相同工况下求得寿命最长的轨道曲线，本文从设计等接触应力内曲线的角度对这类马达作探讨性的研究，主要从以下四个方面进行：(1)综合考虑径向柱塞式液压马达工作时的各种主要受力状况，对柱塞组件进行受力分析，并通过仿真分析影响轨道和滚动体间正压力的各个因素，得到正压力的简化表达式。

因此，有必要对靠模曲线与曲面轮廓线之间关系做以探讨。以仿形车削回转球面为例，讨

RESULTS: Fractal signature of the medial tibial plateau at baseline was predictive of medial knee JSN progression (area under the curve 0.75, of a receiver operating characteristic curve) but was not predictive of osteophyte formation or progression of JSN in the lateral compartment.

结果：内侧胫骨平台的基线分形特征可以预测膝内侧关节间隙缩窄的进展（接受者操作特征曲线下面积 0.75），但不能预测骨赘形成和外侧关节间隙缩窄的进展。

It has the curve warp alarm and signal output functions. The design is based on the acceptable products curve to compare and analyze the test data, so as to make automatic judging and processing.

具有曲线偏差报警及信号输出功能，本设计以合格产品的曲线为基准，对检测数据进行对比和分析，实现自动判定和处理功能。

The results showed that the diurnal changes of photosynthesis of S. chinensis in tile overstory took on "double-peak" curve with remarkable midday depression. The midday depression was mainly due to non-stomata1 limitations. On the contrary, the diurnal changes of photosynthesis of S. chinensis in the understory took on "one-peak" curve with low Pn. The maximal Pn was only half of that of S. chinensis in the overstory. The correlation analysis showed that the limiting factor for this low Pn might be light intensity (p=0.001). Compared with its accompanying plants, S. chinensis was in a disadvantaged status in the community with low photosynthetic capacity, water use efficiency, and the ratio of photosynthetic rate to respiration rate.

结果表明：夏蜡梅冠层的光合速率日进程呈"双峰"曲线，有明显的"午休"现象，经分析其"午休"的原因主要是由非气孔因素引起的；林下夏蜡梅则表现为"单峰"曲线，净光合速率较低，最大净光合速率不及冠层的1/2，相关分析结果表明其最重要的影响因子是光合有效辐射(p=0.001)；与其它伴生植物相比，夏蜡梅的日均光合速率、最大光合速率、水分利用效率和光合速率／呼吸速率都明显偏低，在群落竞争中处于不利地位。
