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。

第二种方法,据有关资料介绍,由于国外厂家还未解决超高压交联聚乙烯电力电缆的中间接头,在绝缘恢复挤塑XLPE交联聚乙烯的工艺过程中,一次挤出的厚度如果过大,达的时候,要保证填充的过大厚度交联聚乙烯层在后期加压加热硫化工艺中,不产生留存有大的气孔。

The results show that a sound bonded interface is obtained without sheet inclusion, pore and unbinding. The microstructure consists of bulk α-Mg phase and needle compound in the weld metal, element Al diffuses along the grain boundary of the substrate into the welding line. A little Y diffuses into the base metal. A little Mn and Cu segregate and element Ni distributes homogeneously and no segregation appears in weld area.

结果表明:界面接合良好,未观察到片状夹杂物、气孔及未焊合等缺陷;焊缝区由块状α-Mg相和针状化合物组成,基体中的Al元素通过晶界扩散偏聚到焊缝中,微量Y元素扩散到基体中,有少量的Mn和Cu元素发生偏聚,Ni元素分布均匀,没有发生偏聚现象。
