将40mm×5mm×2.5mm骨条按不同温度、时间进行烩煅烧处理后，进行气孔率、吸水率、体积密度、抗折强度的测定，以及差热分析、材料矿物组成分析。

The results obtained from the mineragraphy analysis of sintering agglomerates indicate that with 0.03%HPL added, the gas holes of agglomerate becomes smaller so that its strengthen can be improved significantly, and the content of calcium ferrite of good reducibility is increased by 8%-10%.

据矿相分析结果表明，添加0.03％HPL后，烧结矿起气孔变小，使烧结矿强度提高1％左右，并使还原性好的铁酸钙含量增加8％～10％，这有利于高炉冶炼。

Epidermal hairs and stromatal apparatus of Morinda L.

羊角藤属叶表皮毛和气孔器的电镜扫描观察。

The results showed that leaf epidermal cells were polygonous or irregular in shape. Stomatal complexes only present on abaxial epidermis and the stomata was paracytic type. There were five types of anticlinal walls of abaxial and adaxial cells (straight, rounded, undulated, sinuous, straight-curved). Trichomes on abaxial epidermis exist or not. Ornamention types of periclinal walls could be divided into punctuate, smooth and striate. Ornamention of periclinal walls on inner side of abaxial epidermal cells varied widely (irregular, smooth, roughly reticular, micro hairy, granular, scaly).

结果表明：润楠属植物叶表皮细胞形状为多边形或不规则形，气孔复合体均为平列型且仅分布在下表皮；上下表皮细胞的垂周壁式样有5种类型：平直、圆滑、技波、波状、平直－弓形；下表皮毛被有或无；上表皮平周壁纹饰类型有：点状、平滑、条纹；下表皮内面平周壁纹饰类型有：不规则、平滑、粗糙网状、微毛状、颗粒状、鳞片状。
