气管下的

Later on, at Rene's house, ther two boys are playing with paper darts, using a piece of the brass banister they have swiped off the stairway as a blowpipe.

过后在安托万家里，有两个小男孩在玩纸飞镖，他们用来做吹气管的东西，正是从楼梯偷拔下的铜质栏杆。

HISI treatment prolong the survival time of mice in toxic condition induced by sodium nitrite and duration of electrocardiograph in trachea closed mice .HISI could obviously improve the ischemic electrocardiogram T-wave induced by Pituitrin.ST segment drifts on electrocardiogram in acute myocardial ischemia rats induced by Isoprotereno were obviously opposed by administration of HISI. The myocardial infarction areas, releasement of lactic dehydrogenase 、 creatine phosphokinase significantly increased in myocardial ischemia dogs, HISI treatment prevented these effects .

实验结果表明：苦碟子氯化钠注射液能显著延长小鼠常压缺氧环境及亚硝酸中毒情况下的存活时间，延长小鼠气管夹闭后心电消失时间；可显著改善垂体后叶素诱发的大鼠急性心肌缺血心电图T波异常；明显对抗异丙肾上腺素诱导的急性心肌缺血大鼠心电图ST段的偏移；显著改善冠脉结扎所致急性心肌缺血犬的心外膜心电图缩小其梗死心肌面积，降低心肌耗氧量，减少心肌坏死导致的心肌酶如乳酸脱氢酶、肌酸磷酸激酶的漏出。

Results The segmental bronchial ramifications of the left upper lobe were classified into three types mainly: common stem of apical and posterior segmental bronchi (64%, 130/200), trifurcation (23%,45/200), common stem of apical and anterior segmental bronchi (10%, 21/200), and they could be identified in two typical slices of transverse thin-section CT.

左肺上叶3种主要分支类型可以通过薄层CT横断面图像2个典型层面辨认；左肺下叶依据基底干支气管分支的不同分为2种主要类型，Ⅰ型163例(75%)：基底干支气管两分支，即内前底段支气管、外后底段支气管；Ⅱ型39例(18%)：基底干支气管3分支，即内前底段、外侧底段、后底段支气管。

SIgA cell distributed in interstitice Harderian Gland, mainly in epithelium and around gland epithelium of the duct and acini, especially mature plasma cell clung to gland epithelium.

气管中SIgA细胞主要分布在气管黏膜上皮之间和固有膜处，局部黏膜上皮形成小隐窝，隐窝内和隐窝下的固有膜中有较多的SIgA型浆细胞。

In a corner, behind a table leg, in the frays at the end of a mat, or hidden under a heater, they kept turning up.

在小角落，或在桌脚下，或在垫子角的破损处，或在暖气管下，它们一个接一个的出现。

Methods First, 704 patients receiving CO2 laryngeal laser operation from July 2, 2003 to August 21, 2008 were enrolled, and their risk events and causes were systematically analyzed. Second, in vitro experiment, we tested the tolerance of the PVC tube against different CO2 laser energy in different cutting patterns when the cuff was inflated in water or air. We also tested the combustion conditions of the PVC tube in different oxygen concentration, laser energy and cutting patterns. Results Tracheal cuff were punctured by the laser in 92 of all 704 cases. Spark and dense smoke were observed in 8 and 37 cases respectively.

一是统计和分析我院2003年7月2日至2008年8月21日进行的704例喉二氧化碳激光手术所发生的危险情况；二是通过体外试验，观察注水和注空气时气管导管套囊在不同激光能量和不同激光切割方式下对二氧化碳激光的耐受情况，以及PVC气管导管在不同氧浓度、不同激光能量和不同激光切割方式下的燃烧情况。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。

When switching on the machine, the material is conveyed into the grading unit by the feeding devices. The material is separated into fine particle and coarse particle here, the qualified fine particle is released directly from the air pipe; the coarse particle enters the grinding chamber, grinded under high speed strike of the hitting block and then is transferred by the air pipe to the worm grading device. The satisfied particle is released with the exhaust air from the exhaust pipe and is collected as final product.

粉碎时，待粉碎物料由送料装置均匀送到分级室，在这里进行预先分级，原料中的合格颗粒经分级后从排气管排出，粗颗粒进入粉碎室，在冲击锤块的高速冲击和研磨作用下被粉碎，粉碎后的物料经进气管进入的上升气流作用下输送到蜗轮分级机进行先分级，合格颗粒经分级后从排气管随尾气一起排出后收集为产品，粗颗粒再次返回粉碎室继续粉碎。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
