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。

The algorithm tracks the changing rate of each coordinate transformation parameter through Kalman filter to facilitate better prediction of the initial searching point. More importantly, the powers of the noise models of the Kalman filter are effectively estimated online rather than making artificial assumptions on their values. The algorithm can hence adapt to various target motions and searching precisions in a real-time manner without any manual intervention.
该算法通过对坐标变换参数的变化率进行Kalman滤波来更好地预测初始搜索点;更重要的是,该算法有效地在线估计Kalman滤波器中的模型噪声功率,而非先验地对它们的取值做出假设,因而能够在没有任何人工干预的情况下动态地根据不同的目标运动状况和搜索精度进行实时调整。
