However the polar cold water biota can be recognized either by a uniformitarian approach or by a palepbiogeographic approach.

但是极区冷水生物群除了藉助於「均变说」外，亦可利用重建古生物地理之方法来确认。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

结果表明：鹅掌楸亚科和木兰亚科在叶的结构上的主要区别是鹅掌楸亚科两种植物叶的部分下表皮细胞呈乳突状，且整个细胞外壁只形成一个乳突，而在木兰亚科的植物中有单列多细胞或单细胞的表皮毛，未发现乳突；鹅掌楸亚科植物的叶主脉维管组织环分隔呈束状，且其外包被的纤维也排列成束状，而木兰亚科的80种1亚种植物中，叶主脉维管组织连成轮状，其外面也由一圈连续的纤维环所包围。

It is thought that there's an independent neural pathway through which itch is transferred mainly by peripheral unmyelinated C fibers to the most superficial part of dorsal horn, then the lamina Ⅰ spinothalamic tract ascends to the thalami and further projects to the cortex.

目前认为存在独立的痒觉神经传导通路，主要由外周无髓C纤维传入信号至脊髓背侧角的最浅层，Lamina Ⅰ脊髓丘脑束上行至丘脑，进一步投射至皮质区。

In order to study the effect of web openings on the behavior of composite beams under negative moment ,three perforated and one unperforated cantilever composite beams were designed and tested.

为研究腹板开洞对负弯矩区组合梁受力性能的影响，对三根腹板开洞外挑组合梁和一根对比梁进行了试验研究，考虑是否开洞、洞口大小、洞口补强等参数的影响。

Using particle image velocimetercombined with CFD dynamic mesh,an experimental and simulation study was carried out on flow field in the near-wall region outside a vibrating tube.The charts of velocity vector of flow field outside the tube under five conditions with amplitude 1.3 mm and frequency 5—25 Hz were obtained,and the cosine of average synergy angle of flow field outside the tube was calculated.

采用粒子图像测速与CFD动网格相结合的方法，对振动圆管外近壁区流场进行了实验及模拟研究，得到了振幅1.3 mm、频率5～25 Hz范围内的管外流场速度矢量图，计算了不同工况下管外流场的平均场协同角余弦值。

The difference between stumped and run out is that the wicketkeeper may stump a batsman who goes too far forward to play the ball, while any fielder, including the keeper, may run out a batsman who goes too far for any other purpose, including for taking a run.

"持球撞柱"和"截杀"的区别是：捕手可以将击球迈步向前过头的击球手"撞柱"出局，而任何外野手，包括捕手都可以将因任何目的，如获取一跑中，离开安全区的击球手"截杀"出局。

To provide anatomy basis for the implant surgery in the cranio-maxillofacial region ,the three dimensional quantitative measurement of the cranio-maxillofacial region (temporal bone, anterior nasal floor ,orbital rim and zygoma region)were performed in 146 cases.

随着种植医学的进展，种植体的应用范围不断拓展，目前，种植体除广泛应用于口内，制做种植义齿外，还可植入颅颌面缺损区及邻近骨质，作为赝复体的固位基础，为成功解决义耳、义眼、义鼻、义颌等颅颌面赝复体的固位问题提供了途径。

The DGGO had centrally distributed with lobular central node, acinose node or mass. 26 cases were the diseases with abnormity of extravascular fluid overload, including 21 cases' pulmonary edema and 5 cases' contusion of lung. The DGGO had distributed pulmonary pendulous region or relative pendulous region.

以肺内血管外体液量增加为主的疾病有肺水肿21例及肺挫伤5例，肺水肿性磨玻璃影具有沿下垂部分布的趋势，可伴有心影增大及胸腔积液；而肺挫伤性磨玻璃影与外伤部位相关，且在外伤区肺内也具有沿下垂部分布的趋势。

The effects of agmatine on the discharges of neurons in CA1 area of hippocampal slices were examined by using extracellular recording technique.

应用细胞外记录单位放电技术，在大鼠海马脑片上观察了胍丁胺对CA1区神经元放电的影响。

Methods With polymerase chain reaction-single-strand conformation polymorphism combining argentation and glue retrieval, DNA sequencing, and restriction fragment length polymorphism, the SNP of the 50 exons in all the coding regions of ABCA1 gene was detected in 112 patients with established diagnosis of coronary heart disease.
