The influence of several parameters including injection rate of nozzle exit, the ratio of length between nozzle and inner gular tube, the ratio of length between gular tube and it's inner diameter and back pressure on the performance of gas solid injector is analyzed.

分析了喷嘴出口射流速度、喉嘴距、混合管段尺寸及背压等参数对气固喷射器性能的影响，结果表明：存在最佳的喷嘴出口射流速度、喉嘴距以及喉管长与其内径之比使得固气比达到最大值；而背压的增加则不利于提高喷射器性

The effects of half expansion angle , expansion ratio and boundary conditions on performance of 2D micronozzle with half throat heitht 34 were numerically studied.

本文数值模拟喉部半高为34μm的二维微喷管，分别分析了固定进口及固定喉部尺度下扩张角、扩张比以及滑移边界条件对微喷管性能的影响，发现最佳半扩张角在20°-22°之间，而最佳扩张比为7。

The diagnostic criteria,dif-ferential diagnosis and histogenesis of the disease were discussed.

目的 研究喉骨肉瘤的临床病理特征，诊断及鉴别诊断，探索该肿瘤的组织来源方法对1例喉骨肉瘤进行组织形态学和免疫组化研究，结合文献对本病的诊断标准、鉴别诊断及组织来源进行探讨。

CTVE is a new, non-invasive method for demonstrating the mucosal structure of normal and abnormal larynx and hypopharynx, and it is a good complementary method to conventional fiber optic laryngoscopy.

CTVE是一种新的、非侵袭性的方法，能清楚显示正常和异常喉及下咽部的腔内结构，是纤维喉镜的很好补充手段。

Methods CTVE was performed with 3.0 mm at pitch 1.0 and 1.0 mm reconstruction interval in 10 normal subjects and 20 patients with larynx and hypopharynx diseases confirmed by pathology. The results were then compared with the findings of conventional laryngoscopy and operation.

采用层厚3.0 mm、螺距1.0、间隔1.0 mm对10例正常和20例经病理证实的喉及下咽部病变的患者进行CTVE成像，并与纤维喉镜、手术所见对照分析。

All patients had locally advanced squamous cell carcinoma of the oral cavity, oropharynx, larynx, or hypopharynx, and were randomized to either radiation therapy once daily or radiation therapy once daily combined with three courses of high-dose cisplatin chemotherapy.

所有的病人都患有局限性晚期的口腔、喉部、咽部或者喉咽部的鳞壮上皮癌。这些病人被随机给予每日一次放射治疗或者在每日一次放射治疗的基础上加用三个疗程的cisplatin化疗。

Lipomata of the larynx and the hypopharynx are very ram benign lesions; as they look macroscopically like retention cysts, their diagnosis is usually made after surgery.

喉部及下咽部的脂肪瘤是罕见的良性肿瘤，在巨观下会被误认为喉部滞留性囊肿，所以常在手术后才得以诊断。

Objective:To evaluate the roles of EGFR expression in laryngeal keratosis.

目的：观察表皮生长因子受体在喉角化症中的表达，探讨喉角化症的转归和预后。

The incidence of gastroesophageal reflux disease is high in Western nations. Its extra-esophageal manifestations such as asthma, paroxysmal laryngospasm, and excessive throat phlegm, chronic cough, laryngal disorders, postnasal drip and other lesser ear, nose and throat symptoms, have been recognized and reported.

胃食管返流病(gastroesophageal reflux disease， GERD)在西方国家发病率较高，而人们对其食管外临床表现（如哮喘、喉痉挛、顽固性咳嗽咳痰，以致鼻窦炎、咽炎等耳鼻喉科症状）也有相当的认识并有众多的临床报导。

Methods 190 patients were randomly divided into two groups:the trial group with1%dicaine（2ml）and dexamethasone（5mg）for local laryngeal anesthesia before tracheal intubation,the control group as usual methods.To observe the laryngeal edema using fibrolaryngoscope and record the rates of hoarseness,laryngalˉgia after24hours extract tube.

将190例病人随机分为试验组和对照组，试验组在气管插管前后用1%地卡因2ml加地塞米松5mg对声门区及声门下进行表面喷雾麻醉，然后气管插管，对照组常规气管插管对照，术后24h随访，用纤维喉镜检查咽喉红肿情况并记录声音嘶哑和喉痛发生率。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
