1. Today, as in every other day of the year, more than 3,000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3,000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised. First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors exceeded that among female by nearly 10 percent. The statistic is reversing. Third, several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent . Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking levels among youth. 1. According to the author, the deaths among youth are mainly caused by _____. A. traffic accidents B. smoking-related diseases C. murder D. all of these 2. Every day there are over _____young people who will become regular smoker. A. 75 B. 23 C. 30 D. 3,000 3. By "dropout" (in paragraph 3) the author means______. A. students who failed the examination

第三学期专业项目作业

东风本田CR-V空调系统原理组成及故障排除 班级：汽检103班 姓名：聂可举 学号：2010080318

目录 1、绪论 (3) 2、空调的组成 (3) 2.1压缩机 (3) 2.2储液干燥器 (4) 2.3 冷凝器 (4) 2.4管道 (4) 2.5 使用方法 (4) 3、汽车空调的工作原理 (5) 4.汽车空调系统分类 (5) 4.1独立式空调 (6) 4.2非独立式空调 (6) 5、故障诊断与排除 (6) 5.1故障现象 (6) 5.2故障分析 (7) 5.3故障诊断 (7) 5.4故障排除 (8)

1、绪论 一辆本田CR—V因更换冷疑器，重新抽空，加注R134a后无任何异常。当该车行驶中开空调时，从驾驶室听到外部声音异响非常明显，关闭空调，异响消失。此声音不尖不脆．只”咯”、”咯”响，而且随发动机转速升高而消失．在1800～3000r／min时明显。 2、空调的组成 汽车空调一般主要由压缩机(compressor)、电控离合器、冷凝器(condenser)、蒸发器(evaporator)、膨胀阀(expansionvalve)、贮液干燥器(receiverdrier)、管道(hoses)、冷凝风扇、真空电磁阀(vacuumsolenoid)、怠速器和控制系统等组成。汽车空调分高压管路和低压管路。高压侧包括压缩机输出侧、高压管路、冷凝器、贮液干燥器和液体管路；低压侧包括蒸发器、积累器、回气管路、压缩机输入侧和压缩机机油池。 2.1压缩机 压缩机：空调制冷系统的心脏，它是一种使制冷剂在系统内循环的动力源。它的作用是使制冷剂完成从气态到液态的转变过程，达到制冷剂散热凝露的目的。同时在整个空调系统，压缩机还是管路内介质运转的压力源，没有它，系统不仅不制冷而且还失去了运行的动力。压缩机的旋转轴是通过磁性离合器及皮带与发动机曲轴相连取得动力的，这是因为当装在蒸发器出风口的传感器感知出风的温度不够低时，它就会通过电路使压缩机的磁性离合器闭合，这样压缩机随发动机运转，实现制冷。而当出风温度低于设定的温度，它则控制磁性离合

东北农业大学网络教育学院 水工建筑物网上作业题 绪论 一、填空题 1、为了将工程安全和工程造价合理地统一起来，首先应对水利枢纽分_______，然后对枢纽中的建筑物分_______。 2、根据水利水电工程的分等分级指标，将水利水电工程分为等，工程中的水工建筑物分为级， 3、水利工程按其承担的任务可以分为、、、、、等 4、我国水工设计规范规定，设计时一定要保持有安全储备，设计方法有和。 二、判断并改错，对的画√，错的画×，并改正确 1、二等水利枢纽中只能含2级以下主要建筑物和次要建筑物。 2、水利水电枢纽工程的等级按其在国民经济中的作用划分。 三、名词解释 水工建筑物 水利枢纽 水利工程 四、问答题 1、水工建筑物按其作用分类可分为哪几种？各举1例？ 2、水利工程按其对水的作用可分哪几种？ 3、水工建筑物的特点（也是水利工程的特点）有哪些？ 重力坝 一、填空题 1、溢流重力坝既是_ __ _ 建筑物又是 _ _建筑物。 2、波浪三要素是指_ _、_ _ 和_ _。 3、刚体极限平衡法分析重力坝深层抗滑稳定的三种方法分别是 _ _、_ _和 _ _。 4、重力坝的缝按作用分有_ _缝、 _缝和 _ _缝三种。 5、重力坝按构造不同可分为、、三种。 6、重力坝按作用分可分和两种。 7、重力坝按筑坝材料分可分为和两种。 8、泄水重力坝的溢流面由、和三部分组成。 9溢流重力坝的消能方式有_ _、_ _、_ _和 __ _四种。 10重力坝坝体温度变化过程分 _期、_ _期和_ _期三个阶段。 二、判断并改错，对的画√，错的画×，并改正确 1、浪压力在静水位处强度最大。 2、对混凝土重力坝的坝体混凝土进行分区是为了施工方便。 3、扬压力会减小重力坝对坝基面的有效重量，对坝体稳定有利。 4、地基约束引起的应力常引起表面裂缝，故对重力坝而言危害不大。 5、检修闸门的工作条件是在静水中启闭。 6、为了避免坝体开裂重力坝沿坝轴线方向每隔一定距离设置一道横缝。 7、单宽流量越大，溢流孔口净宽愈小，溢流坝长度和配套工程量也愈小，因此选择单宽流量愈大愈好。 8、工作闸门是用来控制下泄流量的，要求能在动水中启闭。 9、重力坝的分缝内均应设键槽，槽面尽量与主应力方向平行或垂直，以减小缝面剪力。 10当下游尾水深低于跃后水深时，应降低护坦高程或采用组合式消力池。 11、重力坝表面裂缝主要是坝体内外温差引起的。
