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。

In this paper, we survey the development of polynomial approximation of rational curves and state the knowledge of interval curves in the first chapter.

Besides The assessment criterion on rectilineal railway, the comfort index N, which is relevant to unbalanced acceleration based on the test result on train running on curve beams, shall also be adopted, on the condition that the transverse stable acceleration is not larger than 0.08g..

列车在曲线桥梁上运行的平稳性除采用直线上的评定标准外，基于国内外曲线上列车运行试验结果，提出同时在横向采用稳态加速度不大于0.08g和未被平衡的加速度相关的舒适度指标N进行评定的建议，并且给出了稳态加速度和未被平衡的加速度的确定方法。

The light scattering data were well described by the crossover model proposed by Anisimov and Sengers, and the effective critical exponentsγandυshowed nonmonotonic crossovers from the 3D-Ising values to the mean-field ones as the temperature departed from the critical point. The coexistence curves exhibited that the values of effective critical exponents for the order parameter of the refractive-index decreased as the distance from the critical point increased, however after the regular terms were subtracted, the nonmonotonic crossovers from Ising to mean-field critical behavior were exhibited. The influence of sodium bromide on the trend of the crossover was small.

静态光散射数据符合Sengers和Anismov等提出的临界跨接理论，关联长度和渗透压缩系数的有效临界指数存在非单调跨接，盐对于跨接程度的影响不明显；共存曲线研究发现，随着偏离临界温度，折射率的有效临界指数逐渐减小，但是当与共存曲线相关的正规项的影响被排除以后，体系表现出从3D-Ising到平均场行为的非单调跨接，盐对于跨接程度的影响不明显。

It offers the idea according to problem faced, considering the good character of the ends,the ajusted cubic B-spline curve is used to fit ship lines.it finds out the control vertexs according to a sequence of given points,and then, through particular formula,each point in the curve could be worked out.

针对面临的问题，提出了自己的思路，在数学计算方法上，由于三次准均匀B样条曲线良好的端部性质，这里用它来拟合船舶型线，首先根据所给的初步型值求出其控制顶点，然后根据相关公式进行插值便能得到曲线上的所有插值点。

According to the identification of fossil woods, it shows that they all belong to Araucarioxylon, with the stage age of Qixia, though there are some anatomical differences among them; Following two mathematical clustering analysis methods-analysis of variance and CSDM curve, metrical numerical values are quantitatively analysed, then, skew value of curve and its relationship with leaf longevity are showed.

经过鉴定研究认为，本区的木化石均属于松柏类中的南洋杉型木属，为栖霞阶化石；应用方差分析、CSDM曲线相关分析等数学聚类分析方法，对木化石标本的测量数据进行了定量分析研究，探讨了曲线偏差值与叶寿命的关系，认为本区二叠纪木化石均为常绿树种-南洋杉型木，但有可能存在落叶树种，且生长年限有较大差异。
