叶轴

In this paper,a numerical method is used to investigate the effects of a winglet attached to an axial fan on the performance.

本文采用数值方法研究了叶片端导叶对轴流风扇性能的影响。

The abaxial surface of a leaf is the underside or side facing away from the stem.

叶子的远轴表面就是背离叶梗底部或旁边的部位。

It was detected that the surface is made up of mainly 4 elements: C, O, N and Al, with little P and F in abaxial leaf.

结果表明，茶树表面主要由C，O，N和Al等四种元素组成，在茶树叶远轴面还有少量的P和F。

The Arabidopsis ASYMMETRIC LEAVES2 (AS2) genes play important roles in specifying the adaxial identity of leaves.

By means of the Fourier series expansion, an approximate analytical propagation equation of flattened Gaussian beams passing through an apertured paraxial ABCD optical system is derived, and illustrated with numerical examples, when the transmissivity of the aperture is T = cos.

Petals 5-7 × 3-5 mm, obcordate, creamy white to yellowish; base of median filaments conspicuously broadened, appendaged, 0.6-1.1 mm wide; leaves pilose or rarely glabrescent; trichomes of inflorescence rachis minutely branched

花瓣 5-7 * 3-5 毫米，倒心形，乳白色的到淡黄色；中间的花丝的基部显著扩大，附属物，0.6-1.1毫米宽；叶具柔毛的或很少后脱落；花序轴的毛状体精确分开 3 H。 rockii 小叶半脊荠

Leaves adaxially or only veins with dense, short, appressed hairs; inflorescence axis densely pubescent

正面的叶是或只脉具紧密的，短，贴伏毛；花序轴密被短柔毛 15

Axial T1 image Figure 4 demonstrates volume loss in the right frontal area with thickened diploic space in this region. Sagittal SE image (Figure 5) shows multiple round signal voids, which are dilated deep medullary veins.

图4轴位T1显示显示右侧额叶体积缩小，相应区域板障增厚，矢状位Se图像（图5）显示多发性圆形流空信号，这是扩张的深部髓质静脉。

And the emeraldine salts (ES2) of polyaniline were prepared by emeraldine base form of polyaniline doped with different acid dopants at room temperature. The structure and morphology of ES1 and ES2 were characterized by Fourier transform infrared spectrometer, Ultraviolet-Visible spectrophotometer and wide angle X-ray diffactometer, respectively.

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。
