The four types of sustainability include human, economic, social, andenvironmental. All four are required to maintain the entirety of life on Earth. Althoughinterconnected, itis importanttonotethedifferences of eachinterms ofits nature and requirements.The very basic need of humansustainability is good reproductive healthandsafe childbearing.Those that reproduce have the responsibility of caring for their children, giving them access to proper education, and promoting their health and wellness. At some point, the childrenshould have enoughskills and knowledge suchthatthey cansustaintheir ownway of life. Itis atthatpointthatthey becomeconsidered as productive human capital as well as individuals that can go through the process of reproduction and rearing. As long as this process is maintained at a rate that all human systems can support, human sustainability should be no cause for concern.Insimple terms, economic sustainability is havinga set amount of capital for acertain period. Those who consume that capital must also conserve it so that they will continue to enjoy it towards the end of the specified period. This means thatwe must preserve all our resources as we consume them so that human beings inthe future can enjoy them as well. To achieve this, we must regenerate our resources at a rate that is equal to or faster than our consumption.Social capital is an important aspect of sustainability because it is through communities and civil societies that humankind can easily and inexpensively work together. Without proper levels of social capital, it can easily deplete and violence as well as mistrustcantake over. Whenthathappens, societies andeverythingelsethat depends on them will be destroyed. Through proper maintenance of and adherencetolaws, rules, andvalues thatsocieties havedevelopedfor thecommongood, social sustainability can be achieved.Environmental sustainability is important because it involves natural resources that humanbeings need for economic or manufactured capital. Materials takenfromnature are usedfor solutions that address humanneeds. If nature is depletedfaster than it can regenerate, human beings will be left without raw materials.Furthermore,environmental sustainability also involves ensuring that waste emissions areatvolumes thatnaturecanhandle. If not, all humans andother livingthings on Earth can be harmed to the point of extinction.可持续性分类四种可持续性包括人类可持续性，经济可持续性，社会可持续性和环境可持续性。

科技英语课文翻译

科技英语课文翻译课文翻译英语Unit 1罗素悖论的提出是基于这样的一个事例：设想有这样一群理发师，他们只给不给自己理发的人理发。

假设其中一个理发师符合上述的条件，不给自己理发；然而按照要求，他必须要给自己理发。

但是在这个集合中没有人会给自己理发。

（如果这样的话，这个理发师必定是给别人理发还要给自己理发）1901年，伯特兰罗素悖论的发现打击了他其中的一个数学家同事。

在19世纪后期，弗雷格尝试发展一个基本原理以便数学上能使用符号逻辑。

他确立了形式表达式（如：应。

一种类比是救护车的汽笛声会改变音高――当它朝你行驶，然后通过你身边接着朝另一个方向去了的时候――他的声波首先是压缩的，接着伸长这些测量给了天文学家一个关于宇宙在不同历史点的膨胀速度的图景。

研究人员还发现宇宙如今正在以前所未有的速度在膨胀。

“一开始我们不情愿相信我们的结果，”加州大学伯克利分校的劳伦斯伯克利实验室的天体物理学家Saul Perlmutter说，他领导的一个竞争性的小组发现了和Schmidt以及Riess 相同的结果。

x =2）和数学特性（如偶数）之间的联系。

按照弗雷格理论的发展，我们能自由的用一个特性去定义更多更深远的特性。

1903年，发表在《数学原理》上的罗素悖论从根本上揭示了弗雷格这种集合系统的局限性。

型的集合系统能很好的用俗称集的结构式来描述。

就现在而言，这种类们可以用x代表整数，通过n来表示并且n大于3例如，小于我7，来表示x={n4，5,6这样一个集合。

这种集合的书写形势就是：我们也可让：n是整数，y={x：3n7}x是美国的一个男性居民。

集合中的对象并不一定是数字。

}。

求的空间。

但是，罗素（和策梅洛一起）发现表面上看，似乎任何一个关于x的描述都有一个符合要a中}导致一个矛盾，就像对一群理发师的描述一样。

x={a：xa它本不再身是在x有致命的打击。

尽管这样，他还不能解决这个问题当罗素发现了悖论，的集合中吗？否定的答案导致了矛盾的出现。

1 Hello. My name is Stephen Hawking. Physicist, cosmologist and something of a dreamer. Although I cannot move and I have to speak through a computer, in my mind I am free. Free to explore the universe and ask the big questions, such as: is time travel possible? Can we open a portal to the past or find a shortcut to the future? Can we ultimately use the laws of nature to become masters of time itself?大家好，我是斯蒂芬-霍金，是物理学家、宇宙学家及梦想家，尽管身体不能活动，只能通过电脑与大家交流，但从内心中我是自由的，自由地探索宇宙，思考以下重大问题：时间旅行是否可行？能否打开一个回到过去的通道，或找到通向未来的捷径？我们最终能否利用自然规律成为掌控时间的主人？2 To see how this might be possible, we need to look at time as physicists do - at the fourth dimension. It's not as hard as it sounds. Every attentive schoolchild knows that all physical objects, even me in my chair, exist in three dimensions. Everything has a width and a height and a length.为了让这一切从虚幻变成现实，我们应以物理学家的角度来重新审视时间——即第四维。

Consider what we know intuitively about an integrator. If you apply a DC signal at the input (i.e., zero frequency), the output will describe a linear ramp that grows in amplitude until limited by the power supplies. Ignoring that limitation, the response of an integrator at zero frequency is infinite, which means that it has a pole at zero frequency. (A pole exists at any frequency for which the transfer function's value becomes infinite.)（为什么为极点，为什么低通？）Figure A simple RC integratorWe also know that the integrator's gain diminishes with increasing frequency and that at high frequencies the output voltage becomes virtually zero. Gain is inversely proportional to frequency, so it has a slope of -1 when plotted on log/log coordinates (i.e., -20dB/decade on a Bode plot, Figure 2. 1b).Figure 2.1 b A Bode plot of a simple integratorYou can easily derive the transfer function asWhere s is the complex-frequency variable and is 1/RC. If we think of s as frequency, this formula confirms the intuitive feeling that gain is inversely proportional to frequency.The next most complex filter is the simple low-pass RC type (Figure 2. 2a). Its characteristic (transfer function) isWhen, the function reduces to , i.e., 1. When s tends to infinity, the function tends to zero, so this is a low-pass filter. When, the denominator is zero and the function's value is infinite, indicating a pole in the complex frequency plane. The magnitude of the transfer function is plotted against s in Figure 2. 2b, where the real component of s () is toward us and the positive imaginary part () is toward the right. The pole at - is evident. Amplitude is shown logarithmically to emphasize the function's form. For both the integrator and the RC low-pass filter, frequency response tends to zero at infinite frequency; that is, there is a zero at. This single zero surrounds the complex plane.But how does the complex function in s relate to the circuit's response to actual frequencies? When analyzing the response of a circuit to AC signals, we use the expression for impedance of an inductor and for that of a capacitor. When analyzing transient response using Laplace transforms, we use sL and 1/sC for the impedance of these elements. The similarity is apparent immediately. The in AC analysis is in fact the imaginary part of s, which, as mentioned earlier, is composed of a real part and an imaginary part.If we replace s by in any equation so far, we have the circuit's response to an angular frequency. In the complex plot in Figure 2.2b, and hence along the positive j axis. Thus, the function's value along this axis is the frequency response of the filter. We have sliced the function along the axis and emphasized the RC low-pass filter's frequency-response curve by adding a heavy line for function values along the positive j axis. The more familiar Bode plot (Figure 2.2c) looks different in form only because the frequency isexpressed logarithmically.（根据图翻译这两句话）Figure 2.2a A simple RC low-pass filterWhile the complex frequency's imaginary part () helps describe a response to AC signals, the real part() helps describe a circuit's transient response. Looking at Figure 2.2b, we can therefore say something about the RC low-pass filter's response as compared to that of the integrator. The low-pass filter's transient response is more stable, because its pole is in the negative-real half of the complex plane. That is, the low-pass filter makes a decaying-exponential response to a step-function input; the integrator makes an infinite response. For the low-pass filter, pole positions further down the axis mean a higher, a shorter time constant, and therefore a quicker transient response. Conversely, a pole closer to the j axis causes a longer transient response.So far, we have related the mathematical transfer functions of some simple circuits to their associated poles and zeroes in the complex-frequency plane . From these functions, we have derived the circuit ’s frequency response (and hence its Bode plot) and also its transient response. Because both the integrator and the RC filter have only one s in the denominator of their transfer functions, they each have only one pole. That is, they are first-order filters .Figure 2.2b The complex function of an RC low-pass filterFigure 2.2c A Bode plot of a low-pass filterHowever, as we can see from Figure 2.1b, the first-order filter does not provide a very selective frequency response. To tailor a filter more closely to our needs , we must move on to higher orders. From now on, we will describe the transfer function using f(s) rather than the cumbersome IN OUT V V . Second-Order Low-Pass FiltersA second-order filter has 2s in the denominator and two poles in the complex plane. You can obtain such a response by using inductance and capacitance in a passive circuit or by creating an active circuit of resistors, capacitors, and amplifiers. Consider the passive LC filter in Figure 2.3a, for instance. We can show that its transfer function has the formand if we defineLC /120=ωand R L Q /0ω=,then where 0ωis the filter's characteristic frequency and Q is the quality factor (lower R means higher Q).Figure 2.3a An RLC low-pass filterThe poles occur at s values for which the denominator becomes zero; that is,when 0/2002=++ωωQ s s . We can solve this equation by remembering that the roots of 02=++c bx ax are given byIn this case, a = 1, b 0ω=, and 20ω=c .The term (ac b 42-) equals ()4/1220-Q ω, so if Q isless than 0.5 then both roots are real and lie on the negative-real axis. The circuit's behavior is much like that of two first order RC filters in cascade . This case isn't very interesting, so we'll consider only the case where Q > 0.5, which means ()ac b 42-is negative and the roots are complex.Figure 2.3b A pole-zero diagram of an RLC low-pass filterThe real part is therefore a b 2/-, which is Q 2/0ω-, and common to both roots. The roots' imaginary parts will be equal and opposite in signs. Calculating the position of the roots in the complex plane, we find that they lie at a distance of0ωfrom the origin, as shown in Figure 2.3b. Varying 0ω, changes the poles' distance from the origin. Decreasing the Q moves the poles toward each other, whereas increasing the Q moves the poles in a semicircle away from each other and toward the ωj axis. When Q = 0.5, the poles meet at 0ω-on the negative-real axis. In this case, the corresponding circuit is equivalent to two cascaded first-order filters.Now let's examine the second-order function's frequency response and see how it varies with Q. As before, Figure 2.4a shows the function as a curved surface, depicted in the three-dimensional space formed by the complex plane and a vertical magnitude vector . Q =0.707, and you can see immediately that the response is a low-pass filter.The effect of increasing the Q is to move the poles in a circular path toward the ωj axis. Figure2.4b shows the case where Q = 2. Because the poles are closer to the ωj axis, they have a greater effect on the frequency response, causing a peak at the high end of the passband .Figure 2.4a The complex function of a second-order low-pass filter (Q = 0.707)Figure 2.4b The complex function of a second-order low-pass filter (Q = 2)There is also an effect on the filter's transient response. Because the poles' negative-real part is smaller, an input step function will cause ringing at the filter output. Lower values of Q result in less ringing, because the damping is greater. On the other hand, if Q becomes infinite, the poles reach the ωj axis, causing an infinite frequency response (instability and continuous oscillation) at 0ωω=. In the LCR circuit in Figure 2.3a, this condition would be impossible unless R=0. For filters that contain amplifiers, however, the condition is possible and must be considered in the design process.A second-order filter provides the variables 0ωand Q, which allow us to place poles wherever we want in the complex plane. These poles must, however, occur as complex conjugate pairs , in which the real parts are equal and the imaginary parts have opposite signs. This flexibility in pole placement is a powerful tool and one that makes the second-order stage a useful component in many switched-capacitor filters. As in the first-order case, the second-order low-pass transfer function tends to zero as frequency tends to infinity. The second-order function decreases twice as fast, however, because of the 2s factor in the denominator. The result is a double zero （零点） at infinity. 低通滤波器一阶滤波器从数学公式上讲，积分器（见图2.1a ）是最简单的滤波器；它是构成大多数现代滤波器的基本模块。

芝加哥的屋顶绿化由于当城市中宝贵的房屋建筑用地已所剩无几，城市规划者开始将目光转向空中。

寻找绿色空间也不例外。

欧洲的绿色屋顶长期以来为人们提供了环境、审美和经济方面的利益。

这种想法是否也会植根在美国植根呢？在伊利诺伊州芝加哥市，当市长理查德•戴利看到了欧洲花园般的屋顶之后，便开始了绿色屋顶的创意。

在最近的一次电话采访时他说：“我认为，如果把芝加哥所有平坦的屋顶都利用起来，可以开辟数千英亩的土地用于美化环境，还有利于建筑物供暖、降温，以及进入排污系统的雨水控制。

”他继续说：“当你透过窗户眺望看这个城市时，你看到的不是钢筋混凝土，而是为对环境的美化。

所以我想，这就是我们应该做的到事情。

”绿色屋顶通常是由无需经常维护的抗旱植物组成（如景天属暑天景植物）。

这些屋顶的厚度均小于4英寸（10厘米），可直接在上面种植或制作成已有植物预先栽种在上面的种植垫。

即使斜屋顶也可以进行绿色屋顶处理。

利用率较高的绿色屋顶系统可以包括多种植物和园林要素，如树木，但只有在平坦的屋顶上才行。

这种绿色屋顶需要更深的种植材料或土壤替代物，它们更重，更昂贵，并且需要更多的维护。

绿化屋顶的最大好处之一是水资源管理。

它们能吸收落在屋顶上的大约50%%-60%%的雨水，这些雨水一部分通过植物蒸发（或“呼气”）回到大气中而消耗掉了，另一部分水保留在土壤中或其他培养媒介中，。

其余的则缓慢地、在人们的控制下缓慢地流入城市雨水排水系统，这个过程有助于抑制城市供水系统中大量雨水激增的现象，而要扩充该系统的费用是很昂贵的。

位于东兰辛伊斯兰莘市的密歇根州立大学植物和土壤学家布拉德•罗说：“在许多城市，甚至一场雷雨就可能造成（雨水的排水系统）溢流，并与污水混在一起。

谁知道它们会流到哪儿去呢？”绿色屋顶的支持者还列举出其他好处，如节省能源。

一个绿色屋顶可以降低多少能源成本，这取决于屋顶类型和使用该屋顶当地的气候。

比较温暖的气候是节省能源的最佳条件，因为与降低取暖费相比，使用绿色屋顶能够更有效地减少空调费用。
