特徵

Sarcomatoid carcinoma is defined as a tumor having both sarcomatous and carcinoma components. Hepatic sarcomatoid carcinomas are rare and often arise from hepatocellular carcinoma or cholangiocarcinoma.

类肉瘤性腺癌系指肿瘤同时表现出肉瘤及腺癌之特徵，肝脏的类肉瘤性腺癌是很少见的而且常常是由肝细胞癌或胆管癌变形而来。

Shortish, greenish bill and black legs indicate this species.

嘴短偏绿色而脚黑色正是三趾鸥的特徵。

Wood structure of six Sonneratia species from Mangrove Nature Reserve at Dongzhai Port, Hainan Province, was observed under LM, SEM and Laser scanning confocal microscope.

研究了海桑科海桑属6种植物的木材结构特徵，并与同科的八宝树属、千屈菜科的紫薇属植物的木材结构进行比较。

The result of clustering based on quantitative data of vessel elements suggests that the Sonneratia species evolved into two clades, one including S. caseoalris and S. paracaseolaris that has the wider vessel and lower pore density suggesting a high conducting efficiency, the other including S. alba, S. ovata, S. apetala and S. hainanensis that has the narrower vessel and higher pore density resulting in high conducting safety.

导管数量特徵的聚类分析可以推测海桑属植物沿两支进化，一支进化为水分输导效率高的种类（即导管直径宽和输导面积大，管孔密度小，如海桑和拟海桑），另一支进化为水分输导安全性高的种类（即导管直径窄、输导面积小，管孔密度大，如杯萼海桑、卵叶海桑、无瓣海桑、海南海桑）。

The spatial structure character of tree populations in a natural Sonneratia caseolaris + S. apetala forest in Futian, Shenzhen was investigated using position index, mixture index, differentiation index, and Ripley's K-functions.

采用位置指数、混交指数、分异指数以及Ripley's K-方程，探讨了深圳福田红树林保护区海桑+无瓣海桑自然林的空间结构特徵。

P procedure. In our model, however, we have used a modified subband structure which is actually the solution of the eigenvalue problem in a 4×4 Luttinger-Kohn matrix.

而在我们的模型里面，我们使用了求解4×4 Luttinger-Kohn矩阵的特徵值的方法来得到修正过的次能带结构。

Although the important crown and undertail covert details are not clear in this photo, the face is rather featureless with a poorly-defined eye-stripe and supercilium.

虽然重要的特徵－冠羽与尾下覆羽的细节在这张照片并不清楚，但这张「没什麼特色」的脸有著对比不明显的眉斑和过眼线。即暗示是艾吉柳莺

Sometimes features as useful as a supercilium can "disappear" due to wear in early spring (and occasionally the entire tail is lost, too).

这只褐柳莺外观不寻常，乃是由於羽毛十分磨损，而且正在换羽中，有时候，一些像眉斑之类有用的特徵，在早春的时候会因为磨损而消失，偶尔连整个尾巴都会不见

Features of male owstoni are: dark green back; bi-coloured ear coverts; white spur on tertials; yellow supercilium reaching the nostril; blue-grey on some median and lesser coverts; rather rounded, short primaries; lack of orange on throat and rump.

owstoni 公鸟的特徵为：暗绿色的背部；双色的耳羽；三级飞羽白色的'刺'；黄色的眉线延伸到鼻孔；部份中覆羽和小覆羽为蓝灰色；有点圆而短的初级飞羽；喉部和腰部没有橘色。

The result shows significant micromorphological differences of leaf epidermis of the seven species and it is taxonomically helpful for the identification of some species with similar leaf morphology.

结果表明该7种植物叶表皮微形态有明显差别，这些表皮特徵有助於识别一些在外部形态较相近的种类。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
