第四单元给水系统 一般来说,供水系统可划分为四个主要组成部分:(1)水源和取水工程(2)水处理和存储(3)输水干管和配水管网。常见的未处理的水或者说是原水的来源是像河流、湖泊、泉水、人造水库之类的地表水源以及像岩洞和水井之类的地下水源。修建取水构筑物和泵站是为了从这些水源中取水。原水通过输水干管输送到自来水厂进行处理并且处理后的出水储存到清水池。处理的程度取决于原水的水质和出水水质要求。有时候,地下水的水质是如此的好以至于在供给给用户之前只需消毒即可。由于自来水厂一般是根据平均日需求流量设计的,所以,清水池为水需求日变化量提供了一个缓冲区。 水通过输水干管长距离输送。如果输水干管中的水流是通过泵所产生的压力水头维持的,那么我们称这个干管为增压管。另外,如果输水干管中的水流是靠由于高差产生的可获得的重力势能维持的,那么我们称这个干管为重力管。在输水干管中没有中间取水。与输水干管类似,在配水管网中水流的维持要么靠泵增压,要么靠重力势能。一般来说,在平坦地区,大的配水管网中的水压是靠泵提供的,然而,在不平坦的地区,配水管网中的压力水头是靠重力势能维持的。 一个配水管网通过引入管连接配水给用户。这样的配水管网可能有不同的形状,并且这些形状取决于这个地区的布局。一般地,配水管网有环状或枝状的管道结构,但是,根据当地城市道路和街区总体布局计划,有时候环状和枝状结构合用。城市配水管网大多上是环状形式,然而,乡村地区的管网是枝状形式。由于供水服务可靠性要求高,环状管网优于枝状管网。 配水管网的成本取决于对管网的几何形状合适的选择。城市计划采用的街道布局的选择对提供一个最小成本的供水系统来说是重要的。环状管网最常见的两个供水结构是方格状、环状和辐射状;然而,我们不可能找到一个最佳的几何形状而使得成本最低。 一般地,城镇供水系统是单入口环状管系统。如上所说,环状系统有一些通过系统相互连接的管道使得通过这些连接接的管道,可以供水到同一个需水点。与枝状系统不同,在环状系统中,由于需水量在空间和时间上的变化,管道中的水流方向并非不变。 环状管网可为系统提供余量,提高系统应对局部变化的能力,并且保证管道故障时为用户供水。从水质方面来说,环状形状可减少水龄,因此被推广。管道的尺寸和配水系统的设计对减少水龄来说是重要的因素。由于多方向水流模式和系统中流动模式随时间的变化,水不会停留在一个地方,这样减少了水龄。环状配水系统的优缺点如表4.1所述。 优点:1.Minimize loss of services.as main breaks can be isolated due to multidirectional flow to demand points.2.Reliability for fire protection is higher due to redundancy in the system.3.Likely to meet increase in water demand -higher capacity and lower velocities.4.Better residual chlorine due to in line mixing and fewer dead ends. 5.Reduced water age. 在文献中曾记载过,只考虑最低成本设计的环状管网系统会转化成树状似的结构,这一做法导致在最终的设计中失去最初的几何形状。环状保证了系统的可靠性。因此,一个只考虑最低成本为依据的设计打败了在环状管网中所提供的基本功能。有文献记载设计环状管网系统的方法。尽管这个方法也是仅以考虑最低成本为基础,它通过对管网中所有管道最优化规划从而保持了管网的环状结构。

Exploring Filipino School Counselors’ Beliefs about Learning Allan B. I. Bernardo [Abstract] School reform efforts that focus on student learning require school counselors to take on important new roles as advocates of student learning and achievement.But how do school counselors understand the process of learning? In this study, we explore the learning beliefs of 115 Filipino school counselors who indicated their degree of agreementwith 42 statements about the process of learning and the factors thatinfluence this process.A principal components analysis of the responses to the 42 statements suggested three factors:(F1)social-cognitive constructivist beliefs, (F2) teacher-curriculum-centered behaviorist beliefs,and (F3) individual difference factors.The preliminary results are briefly discussed in terms of issues related to how Filipino school counselors’ conceptions of learning may guide their strategies for promoting student learning and achievement. [Key words]beliefs about learning, conceptions of learning, school counselors, student learning, Philippines School reform efforts in different parts of the world have focusedon students’learning. In particular,most school improvement programsnow aim to ensure that students acquire the high-level knowledge and skills that help them to thrive in today’s highly competitive globaleconomy (e.g., Lee & Williams, 2006). I n this regard, school reform programs draw from various contemporary theories and research on learning (e.g.,Bransford,Brown, & Cocking, 1999; Lambert & McCombs, 1998).The basic idea is that all school improvement efforts should be directed at ensuring students achieve high levels of learning or attainment of well-defined curricular objectives and standards.For example, textbooks (Chien & Young, 2007), computers and educational technology (Gravoso, 2002; Haertnel & Means, 2003;Technology in Schools Task Force, 2003), and educational assessment systems (Black & Wiliam2004; Cheung & Ng, 2007; Clark, 2001; Stiggins, 2005) are being reconsidered as regards how they can effectively provide scaffolds and resources for advancing student learning. Likewise,the allocation and management of a school’s financial resources are assessed in terms ofwhether these are effectively mobilized and utilized towards improving student learning (Bolam, 2006; Chung & Hung, 2006; Retna, 2007). In this regard, some advocates have also called for an examination of the role of school counselors in these reform efforts (Herr, 2002). Inthe United States, House and Hayes (2002) challenged school counselors to take proactive leadership roles in advocating for the success of all

Laminar and Turbulent Flow Observation shows that two entirely different types of fluid flow exist. This was demon- strated by Osborne Reynolds in 1883 through an experiment in which water was discharged from a tank through a glass tube. The rate of flow could be controlled by a valve at the outlet, and a fine filament of dye injected at the entrance to the tube. At low velocities, it was found that the dye filament remained intact throughout the length of the tube, showing that the particles of water moved in parallel lines. This type of flow is known as laminar, viscous or streamline, the particles of fluid moving in an orderly manner and retaining the same relative positions in successive cross- sections. As the velocity in the tube was increased by opening the outlet valve, a point was eventually reached at which the dye filament at first began to oscillate and then broke up so that the colour was diffused over the whole cross-section, showing that the particles of fluid no longer moved in an orderly manner but occupied different relative position in successive cross-sections. This type of flow is known as turbulent and is characterized by continuous small fluctuations in the magnitude and direction of the velocity of the fluid particles, which are accompanied by corresponding small fluctuations of pressure. When the motion of a fluid particle in a stream is disturbed, its inertia

GRA VITY RETAINING?WALL 1. INTRODUCTION Retaining walls are structures used to provide stability for earth or other material where conditions disallow the mass to assume its natural slope, and are commonly used to hold back or support soilbanks,coal or ore piles, and water. Retaining walls are classified, based on the method of achieving stability, into six principal types (Fig.1). The gravity-wall depends upon its weight, as the name implies, for stability. The cantilever wall is a reinforced-concrete wall that utilizes cantilever action to retain the mass behind the wall from assuming a natural slope. Stability of this wall is partially achieved from the weight of soil on the heel portion of the base slab. A counterfort retaining wall is similar to a cantilever retaining wall, except that it is used where the cantilever is long or for very high pressures behind wall and has counterforts, which tie the wall and base together, built at intervals along the wall to reduce the bending moments and sheers. As indicated in Fig.1c, the counterfort is behind the wall and subjected to tensile forces. A buttressed retaining wall is similar to a counterfort wall, except that the bracing is in front of the wall and is in compression instead of tension. Two other types of walls not considered further are crib walls, which are built-up members of pieces of precast concrete, metal, or timber and are supported by anchor pieces embedded in the soil for stability, and semigravity walls, which are walls intermediate between a true gravity and a cantilever wall.

高速视频处理系统中的信号完整性分析 摘要:结合高速DSP图像处理系统讨论了高速数字电路中的信号完整性问题,分析了系统中信号反射、串扰、地弹等现象破坏信号完整性的原因,通过先进IS工具的辅助设计,找出了确保系统信号完整性的具体方法。 关键词:高速电路设计信号完整性 DSP系统 深亚微米工艺在IC设计中的使用使得芯片的集成规模更大、体积越来越小、引脚数越来越多;由于近年来IC工艺的发展,使得其速度越来越高。从而,使得信号完整性问题引起电子设计者广泛关注。 在视频处理系统中,多维并行输入输出信号的频率一般都在百兆赫兹以上,而且对时序的要求也非常严格。本文以DSP图像处理系统为背景,对信号完整性进行准确的理论分析,对信号完整性涉及的典型问题[1]——不确定状态、传输线效应、反射、串扰、地弹等进行深入研究,并且从实际系统入手,利用IS仿真软件寻找有效的途径,解决系统的信号完整性问题。 1 系统简介 为了提高算法效率,实时处理图像信息,本图像处理系统是基于DSP+FPGA结构设计的。系统由SAA7111A视频解码器、TI公司的TMS320C6701 DSP、Altera公司的EPlK50QC208 FPGA、PCI9054 PCI接口控制器以及SBRAM、SDRAM、FIFO、FLASH等构成。FPGA是整个系统的时序控制中心和数据交换的桥梁,而且能够对图像数据实现快速底层处理。DSP是整个系统实时处理高级算法的核心器件。系统结构框图如图1所示。 在整个系统中,PCB电路板的面积仅为15cm×l5cm,系统时钟频率高达167MHz,时钟沿时间为0.6ns。由于系统具有快斜率瞬变和极高的工作频率以及很大的电路密度,使得如何处理高速信号问题成为一个制约设计成功的关键因素。 2 系统中信号完整性问题及解决方案 2.1 信号完整性问题产生机理 信号的完整性是指信号通过物理电路传输后,信号接收端看到的波形与信号发送端发送的波形在容许的误差范围内保持一致,并且空间邻近的传输信号间的相互影响也在容许的范围之内。因此,信号完整性分析的主要目标是保证高速数字信号可靠的传输。实际信号总是存在电压的波动,如图2所示。在A、B两点由于过冲和振铃[2]的存在使信号振幅落入阴影部分的不确定区,可能会导致错误的逻辑电平发生。总线信号传输的情况更加复杂,任何一个信号发生相位上的超前或滞后都可能使总线上数据出错,如图3所示。图中,CLK为时钟信号,D0、D1、D2、D3是数据总线上的信号,系统允许信号最大的建立时间[1]为△t。在正常情况下,D0、D1、D2、D3信号建立时间△t1<△t,在△t时刻之后数据总线的数据已稳定,系统可以从总线上采样到正确的数据,如图3(a)所示。相反,当信号D1、D2、D3受过冲和振铃等信号完整问题干扰时,总线信号就发生

3单元 地下水位的高低可在一年内大幅波动,下降和上升后,在干燥的季节,降水期。因此,为了保证连续供水,井应穿透许多米水位以下。当水从井里抽水,它在水面产生抑郁,大致锥形的形状,称为漏斗。如果抽重,水表不仅可以降低周围的好但还可延伸到大面积。这在美国西部的部分是这样的。在这种情况下,可以说,地下水被“开采”。即使抽人立即停止,它可能需要数百年的地下水得到补充。下面的例子说明了这一点: 例如,在干燥的美国西南部,含水层补给是每年只有1英寸深的水的十分之二点位置。在这些地区,这是不寻常的泵两英尺或更多的水用于灌溉和其他用途的每年。在这个简单的例子,如果整个含水层抽水的速度,每年的开采量将相当于120年和十年的补给,泵将1200年积累的水。在泵送期间新补给可以忽略不计。机械问题和经济因素阻止完全脱水的含水层,但原则上是有效的例子。 短期承压是适用于任何情况,地下水位上升,在一个以上的水平,这是最初遇到的。这样的情况发生,两个条件必须满足:(1)水,必须限制在一个含水层,是倾斜的,一端暴露在表面,在那里可以得到水;和(2)防渗层,上面和下面的含水层,必须防止水逃避,这样一层被窃听,被上面的水的重量产生的压力会使水上升。如果没有摩擦,井里的水会上升到顶部的水位。含水层。 自流系统作为管道,将水从很远的偏远地区的充电放电点。这样水倒在威斯康星州中部年前现在是从地面和社区许多英里远,伊利诺斯。在南达科他州这样的系统已经从西部的黑山带水,向东跨越国家。在不同的尺度上,城市供水系统可能是人为的自流系统的例子。水塔,为抽水,可能是补给区,管道的承压含水层,在家中的自流井的水龙头。 4单元 矿产勘查在世界表明温度在深油、矿产品通常会增加在地表以下深度增加。在这样的情况下增加温度约0.6度,平均每30米。因此,当地下水在深循环,它变得激烈,如果它上升到表面,水是温泉。一些温泉水在美国,特别是在东部,加热这种方式。在美国,绝大多数的温泉发现于西方。这种分布的原因是,大部分温泉的热源是冷却的火成岩,它是在西方,火成活动已经最近。 间歇泉是间歇性的温泉或喷泉,水柱喷射的伟大力量在不同的时间间隔,通常上升30-60米。水流停止后,一列蒸汽冲出,通常以雷鸣般的轰鸣声。这或许是世界上最著名的间歇泉是黄石公园的老忠实喷发,大约每小时一次。间歇泉也在世界的其他地区,包括冰岛和新西兰,在那里长期间歇泉,意为“喷泉”或“井喷”这个词。 间歇泉时,地下水是地下室加热。室底部,水在巨大的压力下,由于上覆水的重量。因此,一个100度以上的温度就会沸腾所需的前。例如,在一个300米的室内水下必须达到一个温度近230度才开。加热使水膨胀,其结果是某些流出的顶部。这减少了压力,和水变成蒸汽,使间歇泉喷发。 从温泉和间歇泉地下水通常包含在解决方案比其他来源的地下水多材料因为热水比冷水更有效的溶解。当水中含有大量溶解的二氧化硅,硅华沉积在春天。石灰石,方解石的一种,是在石灰岩地区温泉特色存款。一些温泉含硫磺。除了使水的味道不好,硫发出难闻的气味。毫无疑问,臭蛋的春天,内华达州,这种情况。 11单元 一种污染物,是任何物质,生物或化学。在一个可识别的过量的有害的其他理想的生物。在这个框架内,过量的重金属如发汞;某些放射性同位素;氮,磷,钠;和其他有用的,甚至是必要的元素,以及某些致病性细菌和病毒污染物。在某些情况下,材料可作为一种污染物,世界人口中的一段特别的虽然它对其他部分不被认为是有害的。例如,在适当的复合氮超标有害于婴儿,但少了很多成年人如果在所有。在这样的方式,过多的钠盐通常不是有害的,但它可以制约医疗原因盐的摄入饮食的某些人。 不同的物理,地质,生物环境与地下水污染与地表水污染相比是显著的。在后者中,流量和氧气和阳光可用液压,随着速度的过程中污染物的稀释和扩散发生,明显不同于地下水,在污染物降解菌的机会通常局限于土壤或几英尺以下。此外,通过何种渠道地下水运动是非常小的和可变的。由此,显而易见的是,移动速度大大降低,除非,也许,在大的解决渠道内石灰石,以及分散和稀释的机会是非常有限的。此外,地下水通常缺乏氧气,这是造成好氧微生物的种类有帮助但这可能提供了一个“幸福之家”厌氧品种。 大多数土壤和岩石物理过滤出固体的能力,包括污染的固体,是公认的。然而,这种能力会随不同的大小,形状,和滤料颗粒的安排,在选定的沙子和其他材料在水过滤厂使用证明。也知道,但也许不那么普遍,是粘土和其他矿物捕获和交换的一些元素和化合物的能力时,他们游离在溶液中的正或负电荷的元素或化合物。这样的交流,随着吸附和沉淀过程中,污染物的捕获是重要的。这些过程有能力定义的单位是可逆的。他们也可以很容易地在设计设施正确的污染问题所依托的地质环境,土壤和岩石忽视治疗;这种疏忽可能造成地下水污染。这是特别重要的在污水土地应用。 很多猜测,争论,研究发生的地下水污染。地下水污染的主要关注的是化学元素,化合物的引入,和微生物,不含水层,可用于饮用水或是自然发生的,不仅因为该含水层的降解也因为在检测的难度,长期居住,和难度和费用含水层恢复。强有力的论点是,任何废物或可能的污染物应允许进入地下水系统的任何部分。这是一个不可能实现的梦想。相反,答案在于更多的了解自然过程处理废弃物的保证时,土壤和岩石是不能够处理,存储,或回收废物,我们可以发展过程使污染物处理,储存,或可回收。 Extracting and distinguishing environmental change information with high resolution form groundwater and sediments of groundwater system has been the major trend of groundwater sciences towards environmental sciences, This is very useful for forecasting environmental change.4从地下水及其沉积物中提取高分辨率的环境变化信息,实现对环境变化的预警功能是地下水科学向环境科学延伸的重要方向。5而随着全球淡水资源紧缺的形势不断恶化,全球环境变化,特别是全球气候变化对地下水资源的影响成为水文地质研究的新课题。5 With fresh water shortage increasingly serious, the research on effect of globle environmental change, especially globle climate change in groundwater resource has become a new area for hydrogeological research. 4depleted in K and SO4 井的出水量与含水层的渗透系数成正比。 Well water yield is proportional to the transmissivity of a aquifer. 1、分布在这个深层碳酸岩含水层中的地下热水的温度是60℃-90℃。 2、Temperature of the thermal groundwater in the deep-seated carbonate aquifer occurring in this area ranges from 60℃ 3、所有观测井水位的季节性波动可以用研究区降水量的季节性变化来解 4、Seasonal fluctuations in water table in observation wells are interpreted by seasonal changes of/in precipitation in study areas.
