The MWC can operate with as few as p = 2N channels and with a sampling rate fs = 1/T > B on each channel,so that it approaches the minimal rate of 2NB. Advanced configurations enable additional hardware savings bycollapsing the number of branches p by a factor of q at the expense of increasing the sampling rate of each channelby the same factor [109]. The choice of periodic functions pi(t) is flexible: The highest Dirac frequency needsto exceed fmax. In principle, any periodic function with high-speed transitions within the period T can satisfythis requirement. One possible choice for pi(t) is a sign-alternating function, with M = 2L + 1 sign intervalswithin the period T [109, 161]. Imperfect sign alternations are allowed as long as periodicity is maintained [9].This property is crucial since precise sign alternations at high speeds are extremely difficult to maintain, whereassimple hardware wirings ensure that pi(t) = pi(t + Tp) for every t 2 R. The waveforms pi(t) need low mutualcorrelation in order to capture different mixtures of the spectrum. Popular binary patterns, ., the Gold or Kasamisequences, are especially suitable for the MWC [161]. Another important practical design aspect is that the lowpassfilter h(t) does not have to be ideal. A nonflat frequency response can be compensated for in the digital domain,using the algorithm developed in [162].

The thermodynamic calculation is the basis of the compressor calculation. With the help of the compressor-aided design system, the ordinary compressor is able to speed up its progress in calculation, which in turn reasonablizes the design; while the thermodynamic calculation of non-oil lubrication compressor caused errors or inaccuracy when pictures are retrieved by hand and figures are not best chosen. It is towards this problem that the compressor-aided design system for the thermodynamic calculation of non-oil lubrication compressor is made by digitalizing all the pictures and figures. This system will simplize the calculating process of the thermodynamic non-oil lubrication compressor, enable to select data on line, retrieve pictures and figures intelligently, output, save and print them and improve the accuracy and reliability of the calculating parameters as words：compressor , thermodynamic calculation, aided design system, non-oil

The urban river embankment discuss the ecological constructionAnonymous XXXXXXXXAbstract: the urban river embankment construction as the object, discuss the current social background, analyses and compares the river embankment design of traditional methods and characteristics of ecological methods, and puts forward three modes of ecological design and their advantages and disadvantages, and expounds the present situation of the ecological construction in domestic bank and future : the bank; Ecology; Design way; Domestic situationText:A, backgroundRiver Banks part is the amphibious interlaced transition belt, has the remarkable edge effect. Here are active substances, nutrient and energy flow, offer a habitat for a variety of creatures. Natural state Banks often species richness, productivity traditional embankment design often single ?一、背景河流的堤岸部分是水陆交错的过渡地带，具有显著的边缘效应。这里有活跃的物质、养分和能量的流动，为多种生物提供了栖息地。自然状态下的堤岸往往物种丰富、生产力高。传统的堤岸设计往往会单纯从防洪角度出发，采用土堤或者土石混合堆砌起来高高的堤岸。它的优点在于高度的可靠性，结构设计后加起防护堤岸抗流水冲刷能力显著增强。对于洪水暴发频繁、侵蚀严重的区段，这样的设计无可厚非，而对于一般河流堤岸的修建，这样的设计则显得缺乏环境的美化和绿化，同时也破坏许多对生态起重要作用的自然因素，如破坏植被与河床间的联系，造成冲刷侵蚀转移等。另外，河流作为城市风貌不可多得的珍惜资源，也是城市风貌的特色要素，它的景观塑造显得十分必要。同时，堤岸景观建设必然使滨河地区土地价值提升，滨水开发的高投资回报的特点更增强了对城市堤岸景观建设的需求。二、需求——堤岸的生态化建设河流堤岸作为城市中最邻近河流的区域，是城市与河流的衔接线，它的景观规划是提高城市生活品质的需要，也是丰富城市景观的需要。生态化建设，它的根本思路是运用自然本身抗干扰和自我修复的能力来处理人与自然的关系。生态设计方法不同于传统用人工的结构和形式来取代自然的方法，而是用自然的结构和形式来顺应自然的进程。将河岸与河道在生态上联系起来，也就实现了物质、养分、能量的交流：对于生物，它提供了合适的栖息地；植物根系可固着土壤，枝叶可截留雨水，过滤地表迳流，抵抗流水冲刷，从而起到保护堤岸、增加堤岸结构的稳定性、净化水质、涵养水源的作用，而且随着时间的推移，这些作用被不断加强。同时，生态化建设以自然的外貌出现，容易与环境取得协调，造价也较低，不需要长期的维护管理。三、河流堤岸生态化设计方式河流堤岸生态化设计，要遵守生态设计的原则，注重地方性、保护与节约自然资本、让自然做功、显露自然，主要体现在对地域气候环境、河流地质地貌、水文变化的适应，对河流生态环境的考虑，对堤岸地形的处理和对筑堤材料的选择和构造方式方面。1） 人工类：传统方法是采用块石或混凝土块砖等堆砌。可在此基础上加以改进以适应河流景观设计的需求。a) 块石或混凝土块砖干砌，不用砂浆。这样在砌块之间就留有空隙，为后期滨河植物的生长提供了空间。随着时间的推移，堤岸会逐渐呈现出自然的风貌。b) 堤岸采用台阶式分级，台阶面上的空间加以利用，种植植物。当然这两种改进方法对于河岸处现有植被仍存在一定的不良影响，人工痕迹也过于明显。2） 自然类：充分利用堤岸植被原型，可直接将适用于滨河地带生长的植被种植于堤岸上，利用植物的根、茎、叶来稳固堤岸，防止侵蚀、控制沉积的同时也为生物提供了栖息地。3） 人工自然相结合综合了以上两种方法的优点，具有人工结构的稳定性和自然的外貌，见效快、生态效益好，以下为常见的两种类型：a) 种植植物的堆石将由大小不同的石块组成的堆石置于与水接触的土壤表面，再把活体切枝插入石堆中使斜坡更加稳定。根系可提高强度，植被可遮盖石块，使堤岸外貌更加自然。b) 与植物结合使用的插孔式混凝土块将预制的混凝土块以连锁的形式置于岸底的浅渠中，再将植物切枝或植株扦插于混凝土块之间和堤岸上部，其上覆土压实，再播种草本植物。堤岸生态化建设也存在一定的局限性。如：选用的材料及建造方法不同，堤岸的防护能力相差很大，需要运用多学科知识认真分析，这就为设计人员提出了更大的挑战；建造初期若受到强烈干扰，则会影响到以后防护作用的发挥等。这也就对河流堤岸的生态化设计提出了更高的要求。四、国内现状1）省会城市在我国省会城市及计划单列市中有近80％进行了堤岸景观规划。（参考文献[3]）城 市 项目名称 城 市 项目名称北 京 长河城市水系统综合治理 南 宁 堤岸园工程长 沙 湘江风光带 宁 波 滨江大道沿江景观工程成 都 府南河绿化工程 上 海 外滩、陆家嘴滨江大道福 州 闵江江滨公园 沈 阳 浑河观光旅游带广 州 珠江二沙段堤岸景观、芳村长堤建设 太 原 汾河公园贵 阳 南明河景观绿化工程 天 津 海河堤岸改造工程哈尔滨 松花江南岸沿江风景长廊 武 汉 汉口江滩一二期工程昆 明 盘龙江中段滨水生态景观建设 西 安 灞河大水大绿工程兰 州 黄河风情线 重 庆 南滨路滨江旅游观光大道从规划后建成情况看，这些城市河流堤岸景观项目都得到了当地政府与市民的肯定。在这些项目中，堤岸既可成为当地最具吸引力的城市公园，如太原的汾河公园和福州的江滨公园；堤岸也可成为市民日常休闲活动的热点地段，如南宁的堤路园和武汉的汉口江滩工程；堤岸还可成为城市最具特色的地段，如重庆的南滨路滨江旅游观光大道；堤岸更可成为城市旅游的热点，如上海的外滩和陆家嘴滨江大道。总之，经过景观规划的堤岸已成为当地最具特色的地区。从建设效果看，相对堤岸的原来面貌而言，统计资料中的这些景观工程都是较成功的，都成为当地城市关注的热点，成为当地政府的政绩工程，成为当地的民心工程。城市河流堤岸通过景观规划，有效地改善了滨河地段的环境，并带动滨河地段的开发。但必须清醒地认识到，这些城市堤岸景观项目规划并非尽善尽美，也存在这样或那样的问题，仍有待完善。2）中小城市城市经济实力的强大决定了其城市建设水平的高标准和高水平。中小城市河流堤岸景观与统计资料中的城市存在较大的差距，存在更多的问题。特别是由于资金问题，堤岸景观是，纯人工，状态的钢筋混凝土防洪堤，或保持自然防洪状态的土石堤，没有经过景观规划，易造成城市资源的极大浪费。五、前景目前，河流景观建设，特别是城市河流景观建设，在中国正方兴未艾；在发达国家中也是一个久盛不衰的话题。 回顾发达国家河流景观建设的历史，自20世纪70年代以来，随着人们环境意识的普遍增强，重视河流景观的生态功能已成为一个时代的呼唤，河流景观建设的生态设计方法也已得到了空前的重视和发展。他山之石可以攻玉，借鉴发达国家已经形成的成熟的理念和做法，可以使我们少走弯路，搭上隆隆前进的生态建设之车。
