闭塞的

The detailed and thorough analyses of the four images of protagonists are carried out in the second section. They are respectivelyCarol in Main Street, a brave young bride who faces the cultural conflicts with enthusiasm of reformation, and whose dream is still alive waving despite the final return to the parochial Gopher Prairie; Babbitt in Babbitt, the typical "TBM", who is in nature a conformist and doomed to be bounded but tries to escape and finds only failure; Arrowsmith in Arrowsmith, a young medical scientist with grand dream and determination in truth-seeking; and Dodsworth in Dodsworth, a rich, generous, considerate, diligent and down-to-earth car producer.

然后详尽阐述各个人物形象的特点，依次是《大街》中的卡络，一个面对文化冲突勇敢应对，力求革新，虽重新回到狭隘闭塞的小镇，但仍怀有梦想的年轻女性；《巴壁德》中的巴壁德，一个虚伪固执，注定无法摆脱自身局限，却一定要尝试并以彻底的失败告终的房地产掮客；《亚罗史密斯》中的亚罗史密斯，一个怀有梦想并为之终身追求的最具英雄气质的年轻医生；及《道茨沃斯》中的道茨沃斯，一个富有，宽容，体贴，勤奋，脚踏实地，热爱生活的汽车生产商。

Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。

The book contains many case studies of countries at various points on the J curve, from closed to intransition, none of which—even relative successes such as India and South Africa—is unambiguously hopeful.

这本书包括了很多关于研究国家的案例，它们处在J曲线各式不同的点上，从闭塞的到取得阶段性成果的，里面没有一个－甚至象那些相对成功的印度、南非是明明白白有希望的。

Yeh had always treated literature with a serious, persistent attitude and attempted to accomplish. He paid close attention to the peasants who lived in the remote and ill-formed mountain villages and those who were at the bottom of the cities whom were almost forgotten.

叶君健对待文学抱着一种严肃、执着、有所为的态度，他始终关注那些生活在偏僻闭塞的小山村的农民和那些生活在城市底层几乎被人遗忘了的小人物的命运。

Back in my kidhood music was kind of luxury in my isolated mountain village and one of my neighbors, who had got some relative in the town who had passed a used recorder onto him, wired a thundering loudspeaker to this recorder and proudly and loudly, played some out-of-date tapes regularly, 3 times a day, and 3 hours each time.

在我孩提时生活的那个闭塞的小山村，听音乐是件很奢侈的事。当时我有个邻居，他通过托城里的关系得到了一台二手收录机，之后他用金属丝将一个分贝高得像响雷似的扩音器连在收录机上。

The presence of ALN in 16% of patients with branch occlusions appeared to result from variation in the lenticulostriate arteries, which arise from the middle cerebral artery branch in around 20% of cases.

本研究中，有16%的大脑中动脉分支闭塞的患者也出现了豆状核低信号征；我们认为，这可能与豆纹动脉的解剖变异有关，因为有20%的人群地豆纹动脉并非由大脑中动脉M1段发出，而是由大脑中动脉分支所发出的。

We analyzed 77 cases of unilateral or bilateral carotid disease which were diagnosed by TCD and cerebral angiography reported by Lindegaard 1985.The ratio of compensative blood mean velocitywith carotid disease and the identical lateral middle cerebral arterial blood mean velocity－Vm/Vmca can be used as a medium for the analysis of 81(out of 154)laterals carotid pathological changes,which was reported by Lindegaard.

应用15例我科经TCD诊断并由MR、颈动脉双功B超或DSA证实的一侧颈内动脉狭窄或闭塞的病例，与Lindegaard〔2〕报道的77例经TCD和脑血管造影诊断的一侧或双侧颈动脉病变的病例进行分析，将颈动脉病变时代偿血流的平均流速Vm与同侧大脑中动脉平均流速Vmca的比值作为本组15例与Lindegaard的77例81侧颈动脉病变分析的桥梁。

There is no noise in the noise and blocking traffic, there is no air to survive waves of crisis and human indifference. More than 40% of the green rate, exquisite landscape layout, saunters along, the flowers are un, man and nature to reflect the harmony of a comfortable and pleasant!

在这里没有喧嚣嘈杂和闭塞的交通，没有风口浪尖的生存危机和人情的冷漠。40%以上的绿化率，精致的景观布局，闲庭信步期间，鸟语花香枝繁叶茂，人与自然地的和谐体现出的是一种舒适和惬意！

Because mechanical cleaning is critical to the success of subsequent disinfection or sterilization, endoscopes should

因为要成功完成后面的消毒或清洁，人工清洗是重要的，所以应将内镜设计为更加易于清洗，并且无锐利的角度、没有粗糙、多孔或闭塞的表面，这些地方会引起有机物质的积聚（图9）。

Only for women younger than 79 and men younger than 74 years admitted in good condition within 4 days the ICER of occlusion fell below euro 50,000 per QALY.

仅对于年龄小于79岁的女性和年龄小于74岁的男性，且入院状况良好，SAH发作在4天以内的患者，其动脉瘤闭塞的ICER每年低于50，000欧元。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
