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。

For recent years I am in fond of drawing human body for the same appreciation—round, plump and shaped human body is "archy" and "round", outline border is "line" and "square", which are matched with fruits on behalf of life such as "guava""lotus head" and "apple" in the shape of "round" or "half round" put into bottle, plate or pot in the shape of "curve""round" and "half round".

近年我爱画的人体也是基于这样一种感悟——浑圆、丰满、富有曲线的人体呈"弧线"、"圆形"，外框则是"直线"、"方形"，再配以各种代表生命的果实，比如"石榴"、"莲蓬"、"苹果"一类，其造型皆呈"圆"或"半圆"的"放射状"，插在或放在"曲线"或"圆"或"半圆"或"圆中见方"的瓶里、盘里、罐里。

By discussing the position hypothesis of fractional-dimension derivative about general function and the formula form the hypothesis of fractional-dimension derivative about power function, the concrete equation formulas of fractional-dimension derivative, differential and integral are described distinctly further, and the difference between the fractional-dimension derivative and the fractional-order derivative are given too. Subsequently, the concrete forms of measure calculation equations of self-similar fractal obtaining by based on the definition of form in fractional-dimension calculus about general fractal measure are discussed again, and the differences with Hausdorff measure method or the covering method at present are given. By applying the measure calculation equations, the measure of self-similar fractals which include middle-third Cantor set, Koch curve, Sierpinski gasket and orthogonal cross star are calculated and analyzed.
