The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

SBA-15 samples obtained from both silica sources were highly ordered p6mm symmetric pillar structure,as was evidenced by XRD patterns,with similar surface area and slightly larger pore volume for the samples prepared from TEOS than those from sodium metasilicate.

通过X射线粉末衍射对样品进行表征，发现两种硅源合成的SBA-15都具有高度有序的二维六方立柱形结构。它们的比表面积相近，用TEOS作为硅源的SBA-15的孔容比用硅酸钠作为硅源的SBA-15的略大；用硅酸钠作为硅源的SBA-15有更高的微孔率和更厚的孔壁。

Pistillata. However, the mean growth rates of S. pistillata in two mesocosms at 25℃ were significantly different. The mean growth rates of S. hystrix in two mesocosms at 28℃ were significantly different and did not show a consistant relationship compared to those of S. pistillata. The mean growth rates of S. hystrix in two mesocosms at 20℃ were significantly different, but those of S. pistillata were the same.

在25℃的2个生态箱之间，尖枝列孔珊瑚的平均生长率相似，并且大部份都显著高於萼柱珊瑚，而萼柱珊瑚的平均生长率则显著不同；然而，在28℃的2个生态箱之间，尖枝列孔珊瑚的平均生长率变异较大，与萼柱珊瑚的平均生长率比较并无一致的趋势；在20℃的2个生态箱之间，萼柱珊瑚的平均生长率相似，尖枝列孔珊瑚却有显著不同。
