2012专四听写参考答案 Nowadays, many of us try to live in a way that will damage the environment as little as possible. We recycle our newspapers and bottles, we take public transport to get to work, we try to buy locally produced fruit and vegetables,and we want to take these attitudes on holiday with us. This is why alternative forms of tourism are becoming popular in the world. There are a lot of names for these new forms of tourism: responsible tourism, nature tourism, adventure tourism, educational tourism and more. Although everyone may have a different definition, most people agree that these new forms of tourism should do the following: first, they should conserve the wildlife and culture of the area; second, they should benefit the local people; third, they should make a profit without destroying natural resources; and finally they should provide an experience that tourists want to pay for. 2012专四听力参考答案

《传热学期末复习试题库》含参考答案

传热学试题 第一章概论 一、名词解释 1.热流量:单位时间所传递的热量 2.热流密度:单位传热面上的热流量 3.导热:当物体有温度差或两个不同温度的物体接触时,在物体各部分之间不发生相对位移的情况下,物质微粒(分子、原子或自由电子)的热运动传递了热量,这种现象被称为热传导,简称导热。 4.对流传热:流体流过固体壁时的热传递过程,就是热对流和导热联合用的热量传递过程,称为表面对流传热,简称对流传热。 5.辐射传热:物体不断向周围空间发出热辐射能,并被周围物体吸收。同时,物体也不断接收周围物体辐射给它的热能。这样,物体发出和接收过程的综合结果产生了物体间通过热辐射而进行的热量传递,称为表面辐射传热,简称辐射传热。 6.总传热过程:热量从温度较高的流体经过固体壁传递给另一侧温度较低流体的过程,称为总传热过程,简称传热过程。 7.对流传热系数:单位时间单位传热面当流体温度与壁面温度差为1K是的对流传热量,单位为W/(m2·K)。对流传热系数表示对流传热能力的大小。 8.辐射传热系数:单位时间单位传热面当流体温度与壁面温度差为1K是的辐射传热量,单位为W/(m2·K)。辐射传热系数表示辐射传热能力的大小。 9.复合传热系数:单位时间单位传热面当流体温度与壁面温度差为1K是的复合传热量,单位为W/(m2·K)。复合传热系数表示复合传热能力的大小。 10.总传热系数:总传热过程中热量传递能力的大小。数值上表示传热温差为1K时,单位传热面积在单位时间的传热量。 二、填空题 1.热量传递的三种基本方式为、、。 (热传导、热对流、热辐射) 2.热流量是指,单位是。热流密度是指,单位是。 (单位时间所传递的热量,W,单位传热面上的热流量,W/m2) 3.总传热过程是指,它的强烈程度用来衡量。 (热量从温度较高的流体经过固体壁传递给另一侧温度较低流体的过程,总传热系数) 4.总传热系数是指,单位是。 (传热温差为1K时,单位传热面积在单位时间的传热量,W/(m2·K)) 5.导热系数的单位是;对流传热系数的单位是;传热系数的单位是。 (W/(m·K),W/(m2·K),W/(m2·K))

People are just not doing it anymore, especially the young. Who?s responsible? Actually, it?s more like, What is responsible? The Internet, of course, and everything that comes with it —Facebook, Twitter (微博). You can write your own list. There?s been a warning about the imminent death of literate civilization for a long time. In the 20th century, first it was the movies, then radio, then television that seemed to spell doom for the written world. None did. Reading survived; in fact it not only survived, it has flourished. The world is more literate than ever before —there are more and more readers, and more and more books. The fact that we often get our reading material online today is not something we should worry over. The electronic and digital revolution of the last two decades has arguably shown the way forward for reading and for writing. Take the arrival of e-book readers as an example. Devices like Kindle make reading more convenient and are a lot more environmentally friendly than the traditional paper book.
