查询词典 spicular

In Pteridaceae s. l., false veins can be found in Pteris, Adiantum, and vittarioids; in this thesis, Energy Dispersive X-ray element analysis and histochemical studies were used to confirm the false veins of these three taxa are composed of spicular cells – a kind of long, silica depositing epidermal idioblast.

於广义的凤尾蕨科中，假脉可见於凤尾蕨属、铁线蕨属以及书带蕨类群；本论文利用能量色散X光光谱仪元素分析，配合组织化学染色的结果，证实此三类群的假脉均是由具二氧化矽堆积的矽异形细胞(spicular cell， SC)所构成。

The main CT features included marginal spicular signs on the stained hemisphere of longitudinal fis-sure cistern,hematocele signs of the peripheral cistern of brain stem,and molding staining sings of the lateral fissure cistern or the brain surface sulcus.

其主要CT表现特征为：①纵裂池染色半球面边缘毛糙征；②脑干周围池积血征；③侧裂池或脑表面沟铸型染色征。

The results of character evolution history reconstruction shows the SC in PT and AD clade might be a homoplasy character; also, the SC in PT clade might have multiple origins. SC in Pteridaceae has some special characteristics:(1) the cell long axes usually run parallel to the lateral veins;(2) Most of Pteris and Adianum species have VSC only in lower epidermis;(3) Species have ISC also have VSC.(4) Presence of spicular cells is highly correlated with the long veinal epidermal cells. Species have type III silica deposition type usually have longer and narrower veinal epidermal cell compared with ordinary epidermal cells; Species have type IV silica deposition type also have long epidermal cells, but not significantly different from ordinary epidermal cells.

本实验中亦发现凤尾蕨科之矽异形细胞具有几项特色：(1)矽异形细胞之长轴多与叶片侧脉方向平行(2)发现多数铁线蕨属以及凤尾蕨属植物仅下表皮具有脉上矽异形细胞；(3)具有脉间矽异形细胞的种类会同时具有脉上矽异形细胞；(4)长条形的侧脉上表皮细胞与矽异形细胞具有相关性，仅具脉上矽异形细胞的分类群之脉上表皮细胞均较一般表皮细胞细长；具有脉间矽异形细胞之物种之脉上表皮细胞亦为长条形但形态与一般表皮细胞常无明显形态差异。

We named the spicular cells which forming false veins interveinal spicular cells, and the spicular cells on veins are veinal spicular cells in this thesis.

本论文将此构成假脉之细胞称为脉间矽异形细胞(interveinal spicular cell， ISC)，而将分布於叶脉上的矽异形细胞称为脉上矽异形细胞(veinal spicular cell， VSC)。

20th century budism proses in China rise and flourishing in a spicular cultural background.this paper classfies these presentive writings into four sections,and analyses the characatoristics of all these writings.

二十世纪中国佛教散文在一定的文化背景下产生、繁荣，它是值得人们研读的佳品，本文就其中有代表性的篇章分四大类进行分析和欣赏，试图发掘其最闪光的地方

Results Nine of the tumours exhibited a solid tumour growth pattern:most of them showed a well defined,homogeneous,soft tissue density with spicular or...

结果9例患者呈实体瘤样生长，多数分界清楚、质地均匀、带有毛刺和分叶的软组织密度影，阴影内缺乏支气管充气征和小泡征。

Based on these characteristics observed, species in Pteridaceae tended to accumulate and deposit silica in long cells in lower epidermis and forming spicular cells. This might helps them to enhance the supporting function of their lateral veins.

综合以上特徵推测，凤尾蕨科倾向将二氧化矽堆积於叶下表皮与叶脉平行之表皮细胞上，并形成矽异形细胞，该特徵可能与加强叶片的支持力有关。
