后翼

A variant of the swept-back wing is the delta wing.

后掠翼的变型是三角翼。

Methods: Radioimmunoassay was used to examine the level of insulin in lateral pterygoid muscle quantitively after functional mandibular protrusion in young growing rats.

采用放射免疫分析技术分别检测实验组和对照组大鼠翼外肌内胰岛素的含量。结果：功能矫形前伸下颌后，生长期大鼠翼外肌内胰岛素含量增加。

A new kind of subsoiler with adjustable wines has been developed and thestructure of soil after subsoiling is also studied,it is found that thissubsoiler can loose whole surface of soil with intervally looseing the deepsoil,making a better seed bed for planting narrow row spaceing crops such aswheat.

分析了可调翼深松铲的入土性能，研究了松后土壤结构，试验发现，利用安装位置较高的可调翼深松铲，可以为小麦覆盖地创造"表层全松底层间松"的土壤结构，这种结构有利于行距较小的小麦等密植作物播深均匀，该深松方法与原理具有新意。

Blade simulation computer is used to receive data from hypogynous machine and draw dynamic chart to simulate blade rotation.

旋翼动画模拟机主要接收下位机的测量数据，经计算处理后得到共锥度的值；同时绘制旋翼三维动态模拟画面，并叠加一些从主控机传来的环境参数值。

A multiminate layer vapor screen technique and force measurement technique for an unsteady flow in the intermitted wind tunnel is presented in this paper.

本文介绍在暂冲式三声速风洞中实现了非定常流动的多片光蒸汽屏显示技术和测力技术，并用这两项技术研究了亚声速时70°后掠三角翼模型俯仰振动的非定常流动现象，探讨了由于三角翼模型俯仰振动产生的涡结构与纵向气动力特性之间的相关关

Methods:Wistar rats were divided randomly into sham-operation group(n＝6) and ischemia- referfusion group (n＝12).Common carotid artery and external carotid artery were ligated,internal carotid artery and pterygopalatine artery were undivided.Pricking with eye scissors at the distal end of CCA for intralumin suture.By adjusting the suture arc direction to avoid entering the pterygopalatine artery,then withdraw the suture for referfusion 1 h later.

采用健康雄性Wistar大鼠随机分为假手术组(n＝6)和缺血再灌注组(n＝12)，其中缺血再灌注组结扎颈总动脉和颈外动脉，颈内动脉和翼腭动脉不予分离，眼科剪在CCA远端上剪一小口插入线栓，通过调整线栓弧度方向来避免进入翼腭动脉，造成缺血，1 h后外拉栓线形成再灌注。

There were two layers of tissue in the pterygopalatine fossa,they are posteromedial nerve layer and anterolateral vessel layer.The distance from the internal carotid artery to the sphenopalatine foramen was 16.4±3.3 mm.

结果：蝶腭孔、圆孔、翼腭裂距离前鼻嵴的距离分别为(62.3±2.7)、(64.2±4.8)、(51.5±0.6) mm，翼腭窝内的结构可以分为在后内的神经层和在前外的血管层，颈内动脉与蝶腭孔之间的距离为(16.4±3.3) mm。

So "the egg" may be one answer to the old riddle, but here's another, if a little longer: The chicken came after the bird, the bird came after the dinosaur, the dinosaur came after the egg.

因此，&先有蛋&或许是这个老谜题的一个答案，但如果多费一点笔墨，这里有另一个答案：鸡在鸟之后出现，鸟在翼龙之后出现，翼龙在蛋后出现。

You may have noticed that autogyro rotors are not located on top of the mast, but somewhat after the top on the

你也许注意到了，旋翼机的旋翼并不位于桅杆的顶部，而是在桅杆顶部靠后些的位置与扭矩管相连。

The tail boom tapers from the main body to the swept-back, tapered fin with a rotor on the right. Two flats are mounted on the both side of the boom.

尾梁从机身渐细到后掠尾垂翼，尾螺旋桨在锥形尾垂翼右侧，二个尾平翼被装在尾梁两侧。
