食道的

The result showed that, the body wall most outer layer cuticle assumesthe translucent porodine, the surrounding entire body wall; Close isconnected with the cuticle 表皮层 for 合胞体 the structure, inthe back, the abdomen and its two sides separately adds thick to inprominent Cheng Jizhuang, separately contains the back side,腹侧the nerve and compares to the developed back, the abdomen nerve; Themyo- position to the body wall most inner layer, has the muscle cellto arrange becomes; Between the body wall and the digestive tractcavity is a body cavity; Digestive tract for 肌质 structure, afterinference for roundworm's esophagus.

结果显示，体壁最外层的角质层呈半透明的胶状，包围整个体壁；与角质层紧密相连的表皮层为为合胞体构造，在背、腹及其两个侧面分别加厚向内突出成脊状，分别包含背侧、腹侧神经和相比对发达的背、腹神经；肌层位于体壁最内层，有肌细胞排列而成；体壁与消化道之间的空腔为体腔；消化道为肌质结构，经推断为蛔虫的食道。

The regurgitant volume was calculated by temporally integrating the instantaneous flow volume rate of each frame during systole.

建立了基于经食道旋转扫描二维和经胸实时三维超声多普勒血流图像获取方法和图像插值、配准算法获得体数据，经多维重建描述二尖瓣反流速度的空间分布，立体观察返流的时相、方向、反流束长度、面积、体积、空间传播和严重程度等；通过重建反流后的速度场，从血流动力学角度分析了二尖瓣反流的性质，计算偏心反流束的湍流强度，利用反流束角度和湍流强度对计算结果进行修正；基于实时三维彩色多普勒成像技术，利用控制体原理对二尖瓣反流束在反流瓣口横断面的速度分布进行空间与时间积分获得二尖瓣偏心性反流的每搏反流量。

He says his research, which he hopes to get published in a veterinary journal, shows compressed vegetable chew treats, of which Greenies is the most popular, are now the third biggest cause of esophageal obstruction in dogs behind bones and fish hooks.

他说这份他希望能在兽医期刊中发表的研究报告中显示，经压缩处理过的蔬菜嚼骨零嘴(Greenies是其中最受欢迎的)目前是继骨头及鱼刺后第三大造成狗狗食道阻塞的原因。

Stranger still was what he found inside them: Their huge stomachs contained masses of chewed-up jellyfish, stinging tentacles and all, and their gullets were lined with three-inch spines, angled inward to hold in all that slippery prey.

更怪的是他从牠们体内找到的东西：牠们巨大的胃里有大量嚼碎的水母，包括带刺的触手；而牠们的食道内排列着长七公分的刺，这些刺向内倾斜，好钩住滑溜溜的食物。

The main symptom of a hiatus hernia is severe heartburn and regurgitation, when stomach acid refluxes back into the oesophagus, causing a deep burning pain behind the breast bone, made worse by bending forward, by straining and by lying down.

主要症状的一裂孔疝是严重的心和逆流，当胃酸refluxes回复到食道，造成了深刻的烧灼痛背后的乳腺癌骨，而变得更加严重弯曲着，紧张和躺下。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
