练习题5—心律失常

练习题5—心律失常

练习题【1】冠心病患者突感心悸,胸闷,血压为90/60mmHg,心尖部第一心音强弱不等,心电图示心房率慢于心室率,二者无固定关系,QRS波增宽为0.12s,可见心室夺获和室性融合波。

该患者首先应该考虑的疾病诊断是A、心房扑动B、心房颤动C、多发性室性期前收缩D、阵发性室性心动过速心室夺获波与室性融合波是确诊室性心动过速的最重要依据。

【2】终止心室颤动最有效的方法是A、胺碘酮B、利多卡因C、电复律D、阿托品非同步直流电除颤是终止心室颤动的首选方法。

电复律和电除颤的区别电复律是心律失常治疗电转复的一个总称,其包括电除颤。

电除颤是采用非同步直流电复律使心脏除极,来恢复窦房结正常的起搏功能。

【3】下列有关房室传导阻滞治疗的叙述,不正确的是A、一度房室传导阻滞通常无需特殊治疗B、有Adam-Stroke综合征发作者应给予起搏治疗C、阻滞位于房室结时可用阿托品治疗D、药物治疗可长期使用一度、二度I型房室传导阻滞心室率不太慢时,无需特殊治疗。

二度II型、三度房室传导阻滞心室率显著缓慢,甚至发生Adams-Stroke综合征,应给予起搏治疗。

阿托品可提高房室传导阻滞的心率,适用于阻滞位于房室结的患者,但药物治疗效果不佳且易发生严重的不良反应,仅适用于应急情况。

阿斯综合征是心源性脑缺血综合征,是指突然发作的,严重的,致命性缓慢性或快速性心律失常,心排血量短时间内锐减,产生严重脑缺血,神志丧失,和晕厥等症状。

临床表现:短暂意识丧失,面色苍白,紫绀,血压下降,大小便失禁,抽搐等,心跳停止2-3秒可表现为头晕,4-5秒则面色苍白、神志模糊,5-10秒则可出现晕厥,15秒以上则发生抽搐和紫绀。

症状发作时心音消失,脉搏和血压测不到,心电图可出现窦性停搏,室速,室颤,严重窦缓等。

【4】同步电复律的最佳适应证是A、阵发性室上性心动过速B、心房颤动C、心房扑动D、心室颤动心房扑动是同步电复律的最佳适应证,成功率几乎100%心房扑动是一种药物难以控制的快速型心律失常,当心房扑动以1:1比例下传时,心室率快,可导致血流动力学迅速恶化,甚至危及生命,但电复律往往会取得成功。

《抽样技术》练习题5及答案

《抽样技术》练习题5及答案

《抽样技术》练习题5及答案习题⼀1.请列举⼀些你所了解的以及被接受的抽样调查。

2.抽样调查基础理论及其意义;3.抽样调查的特点。

4.样本可能数⽬及其意义;5.影响抽样误差的因素;6.某个总体抽取⼀个n=50的独⽴同分布样本,样本数据如下:567 601 665 732 366 937 462 619 279 287690 520 502 312 452 562 557 574 350 875834 203 593 980 172 287 753 259 276 876692 371 887 641 399 442 927 442 918 11178 416 405 210 58 797 746 153 644 4761)计算样本均值y与样本⽅差s2;2)若⽤y估计总体均值,按数理统计结果,y是否⽆偏,并写出它的⽅差表达式;3)根据上述样本数据,如何估计v(y)?4)假定y的分布是近似正态的,试分别给出总体均值µ的置信度为80%,90%,95%,99%的(近似)置信区间。

习题⼆⼀判断题1 普查是对总体的所有单元进⾏调查,⽽抽样调查仅对总体的部分单元进⾏调查。

2 概率抽样就是随机抽样,即要求按⼀定的概率以随机原则抽取样本,同时每个单元被抽中的概率是可以计算出来的。

3 抽样单元与总体单元是⼀致的。

4 偏倚是由于系统性因素产⽣的。

5 在没有偏倚的情况下,⽤样本统计量对⽬标量进⾏估计,要求估计量的⽅差越⼩越好。

6 偏倚与抽样误差⼀样都是由于抽样的随机性产⽣的。

7 偏倚与抽样误差⼀样都随样本量的增⼤⽽减⼩。

8 抽样单元是构成抽样框的基本要素,抽样单元只包含⼀个个体。

9 抽样单元可以分级,但在抽样调查中却没有与之相对应的不同级的抽样框。

10 总体⽬标量与样本统计量有不同的意义,但样本统计量它是样本的函数,是随机变量。

11 ⼀个抽样设计⽅案⽐另⼀个抽样设计⽅案好,是因为它的估计量⽅差⼩。

12 抽样误差在概率抽样中可以对其进⾏计量并加以控制,随着样本量的增⼤抽样误差会越来越⼩,随着n越来越接近N,抽样误差⼏乎可以消除。

理论力学习题(5)

理论力学习题(5)

第五章 思考题5.1 虚功原理中的“虚功”二字作何解释?用虚功原理解平衡问题,有何优缺点?答:“虚功”是指作用在质点上的力(包括约束反力),在任意虚位移过程中所做的功。

因虚位移是假想的位移,所以虚功也是假想的功。

不一定是质点在任何真实运动中力实际所完成的“真实功”。

而虚功原理中的“虚功”只包括所有主动力的“虚功”,不包括约束反力的“虚功”,因为根据理想约束的条件:∑==⋅ni i i10r Rδ,即作用在一力学体系上的所有约束反力在任意虚位移中所做的虚功之和为零。

用虚功原理解平衡问题时,约束反力自动消去,这是它的优点。

但因此就不能直接用它来求约束反力,这是它的缺点。

5.2 为什么在拉格朗日方程中,αQ 不包括约束反作用力?又广义坐标及广义力的含义为何?我们根据什么关系可以由一个量的量纲定出另一个量的量纲?答:决定力学体系的位置状态的独立参数叫广义坐标。

广义坐标不一定是长度,也可以是角度、面积或体积等。

与广义坐标对应的广义力定义为:∑=∂∂⋅=ni ii q Q 1ααr F 它可以是力或力矩,也可以是其它物理量。

我们根据关系:∑==sq Q W 1αααδδ,可由广义坐标的量纲定出广义力αQ 的量纲(功的量纲已知)。

根据广义力的定义,我们可以计算与约束反力相应的广义力:∑=∂∂⋅=ni ii Rq Q 1ααr R 但理想约束条件:0)(11111=∂∂⋅=∂∂⋅=⋅∑∑∑∑∑=====ααααααδδδq q q q ni i i s ni si i ni i rR r R r R i ,由于αδq 是独立的,所以有:),2,1(01s q Q ni ii R==∂∂⋅=∑=αααr R 。

我们看到,只要满足理想的约束条件,约束反力对广义力的贡献为零。

因此,αQ 中不包含约束反力。

5.3 广义动量αp 和广义速度αq是不是只相差一个乘数m ?为什么αp 比αq更富有物理意义?答:广义动量αp 和广义速度αq的关系只能由定义式:ααqLp ∂∂=求出,他们不一定是只相差一个乘数m 。

You mayeven have entered the shop just to find shelter from a suddenshower. Whatever the reason, you can soon become totallyunaware of your surroundings. You soon focus on some book orother, and usually it is only much later that you realize you havespent too much time there and must hurry off to keep someforgotten appointment.This opportunity to escape the realities of everyday life is the mainattraction of a bookshop. A music shop is very much like abookshop. You can range round such places to your heart's content.If it is a good shop, no assistant will approach you with the greeting,"Can I help you?" You needn't buy anything you don't want. In abookshop an assistant should remain in the background until youhave finished reading. Then, and only then, are his servicesnecessary.Once a medical student had to read a textbook which was far tooexpensive for him to buy. He couldn't obtain it from the library andthe only copy he could find was in a bookshop. Every afternoon,therefore, he would go to the shop and read a little of the book at atime. One day, however, he was disappointed to find the bookmissing from its usual place. He was about to leave, when henoticed the owner of the shop making a gesture to him with hishand. Expecting to be scolded, he went towards him. To hissurprise, the owner pointed to the book which was put away in acorner. "I put it there in case anyone had a desire to buy it!" he said,and left the delighted student to continue his reading.1.Time spent in a bookshop can be most pleasant_______________.A. only when you can find the book you want to buyB. only when you are a book-loverC. even when you enter it to avoid a sudden showerD. even when you know you are late for an appointment2. A bookshop is of much attraction because ______________ .A. it offers you an opportunity to forget about everyday lifeB. it offers you an opportunity to listen to as much music aspossibleC. it allows you to learn about new ideas and ways of doingthingsD. it allows you to have a good excuse for being late for anappointment3.In a good bookshop __________.A. an assistant should always follow youB. an assistant should frequently approach you and offer helpC. you needn't buy anything you don't wantD. you can communicate freely with an assistant4.The medical student went to a bookshop every day_____________.A. to look for useful booksB. to read a textbookC. to talk with the shop ownerD. to use the computer at the shop5.The owner of the bookshop put away the book______________.A. in case other people wanted to buy itB. in case the medical student wanted to buy itC. because he wanted to sell it at a high priceD. because he wanted to keep it for himselfQuestions 6 to 10 are based on the following passage.In the United States, it is not normal to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 p. m. If someone receives a call during sleeping hours, he assumes it's a matter of life and death. The time chosen for the call communicates its importance.In social life, time plays a very important role. In the US guests tend to feel they are not highly regarded if the invitation (邀请) to a dinner party is extended only three or four days before the party date. But this is not true in all countries. In other areas of the world it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten.The meaning of time is different in different parts of the world. Thus, misunderstandings arise between people from cultures that treat time differently. To be on time is valued highly in American life, for example.

People called this thetime of the Gold Rush.A gold miner came into a city looking for a pair of pants. He wantedpants strong enough to stand up to the rough work of mining. Hemet a young man named Levi, who sold heavy cloth for tents andwagon tops. They asked a tailor to use heavy cloth for their pants. Then Levi went into the business of making work pants. He asked his brothers to send him some strong blue cotton cloth called denim (斜纹粗棉布). With this blue denim cloth, Levi started making the kind of pants we call blue jeans today. They were sewed up in the same way as other pants.In 1860, a miner said that the pockets weren't strong enough to hold the pieces of gold he found. The pockets kept falling off the pants. The cloth was all right. It was the thread that wasn't strong enough. So Levi used rivets (铆钉) to attach the pockets onto the pants.Cowboys needed tough pants, too. They liked their pants to fit tightly. But the rivets marked the cowboys' saddles. So Levi covered the rivets with cloth. Then everybody was happy.1.This article as a whole is about __________________.A. how people got blue jeansB. the Gold Rush in CaliforniaC. How blue jeans are madeD.

Rote-learning (死记硬背), spoon-fed education, produces a brand of kids that don't know what to do when entering university. They are disciplined into following, not leading. Yet the future depends on creativity and imagination. The world needs creators, makers and shakers of the new centuries, not the followers of the past centuries. As the numbers increase at college and university level, more students from the lower ends are likely to be thrown into a process designed to choose only learners that have proved excellent in listening to teachers.There are three ways to learn: looking, listening and doing.Students and teachers today are a product of learning by listening. The computer may not be liked by traditional teachers, who use rote-learning to put information, which will be out of date in a few years, into the heads of the students. With computer learning you learn by looking, listening and doing; you use three methods oflearning, not just one. Therefore, you can learn faster.The changing speed of information is frightening. What we learn now will be out of date in the near future. So what students are learning now at school may be replaced by the time they finish university. We have to learn by choice what to forget. Rote-learning for exams is one thing, but wouldn't it be better to learn how to learn? The students at university today could possibly be doing a job in the not too distant future which has not yet been invented.6.According to the author, the future doesn't need____________.A. creativityB. imaginationC. creatorsD. followers7.In the author's view, how can students learn well?A.

We don't have enough time to adjust ourselves to the speedof information.B. What we learned today may not be useful tomorrow.C. The pace of life is too fast.D. The world is changing every minute.9.What does the last sentence of the passage tell us?A. Rote-learning is completely harmful.B. Students may have to do jobs which are not yet inexistence.C. It's better to learn how to learn than learn what to forget.D. Students must imagine the future.10.The author's attitude towards rote-learning is _________.A. approvingB. disapprovingC. confidentD. opposite to what the words say。
