分贝仪 article Full article /magsdirx/ax/addenda/media/koya2811.pdfThis article investigates the characteristics of the Radio Shack Sound Level Meter in regard to its accuracy.The Radio Shack Sound Level Meter is a versatile and economical device, used for calibrating home theater speaker levels, subwoofer level matching to main speakers, low-frequency room-mode analysis, and measuring loudspeakers. Conveniently, an output jack is provided on these sound level meters, which allows connections to personal computer sound cards, and permits usage of these devices via PC-based acoustic measurement programs. But how accurate is this device and is it the appropriate tool to be used in the aforementioned activities?The Radio Shack Analog-Display Sound Level Meter (referred to hereafter as the RS SPL meter) has seen a model change. The new version (Photo 1, model number: 33-4050) is more compact than its predecessor. I assume that many users still own the older, now-discontinued version (Photo 2, model number: 33-2050), so I include it here. The Radio Shack Digital-Display Sound Level Meter (Photo 3, model number: 33-2055) features a digital readout of the sound level instead of a moving needle.I had access to two of the older-model RS SPL meters, one new model, and a digital version. I used these four units for this study.FREQUENCY RESPONSEDETERMINATION METHODI devised a method to determine the frequency response of the four RS SPL meters. First, I took a reference measurement using a calibrated Mitey Mike II microphone and a custom-made microphone preamplifier. From its specification sheet, the Mitey Mike II has a flat response in the low-frequency range, to 20Hz. The custom-made microphone preamplifier was designed to have a flat frequency response down to DC. I used LMS, which uses stepped sine signal acquisition1, to perform all acoustic measurements.One speaker I used in making this reference measurement was a 6½˝ two-way bookshelf speaker with a relatively flat frequency response (88Hz ~ 20kHz， ±2dB). Because the bookshelf speaker's frequency response extends down to only 88Hz (-3dB), I used a subwoofer with an approximately flat frequency response down to 16Hz (16Hz ~ 200Hz， ±2dB) to ascertain the low frequency region. I measured the bookshelf speaker using the ground-plane method2 and the pseudo-anechoic (gated3) method.I performed both measurement methods for the bookshelf speaker because when the RS SPL meter is placed flat on the ground, its microphone element edge is about 1cm off the ground. I surmised that this height differential in the ground-plane measurement may limit high-frequency accuracy4. Therefore, for high frequencies (above 500Hz), I used pseudo-anechoic measurements, which place the RS SPL meter microphoneTube, Solid State,Loudspeaker TechnologyPHOTO 1: RS Sound level meter (new model).。

4.关于分布式能源的外文和翻译 文献翻译 毕业论文
分布式能源系统究竟如何定义，现在有两种理解：一是靠近用户的小型发电或蓄电系统；另一种是利用天然气作燃料的冷热电联产12万~40万千瓦的大机组。
笔者认为，既然称为分布式能源系统应当是第一种理解，第二种只能称为冷热电联产系统，不是分布式能源系统，只有小型的冷热电联产系统可以称为分布式能源系统。 能源辞典关于分布式能源是这样说的：“靠近用户的小型发电或蓄电系统。
它可以大大减少输送、分配成本，联产达到很高的效率，减少CO2和大气污染物的排放，提高供电质量和可靠性，更多的终端用户控制。这些优点将使能源工业发生革命性的变化。
它采用可再生能源发电，没有或很少大气污染物和CO2排放，采用燃料电池、微型燃气轮机和内燃机，总的排放量也可减少，利用余热可提高能效。目前，分布式发电大多是备用电源，用于医院、工厂、因特网服务器等供电中断代价大的地方，还用作边远地点的独立电源。
它对发展中国家有很大好处，因为它的基础设施投入少。

题目：Geothermal resources 正文：Geothermal resources in the world's oldest energy sources. It is estimated that the total thermal energy of the Earth's interior, about all the coal reserves of about 1.7 billion times. Year from Earth's interior heat loss through the surface, equivalent to 1,000 million barrels of oil burning heat. On geothermal sources, there are several hypotheses. Is generally believed that the geothermal evolution of radioactive elements mainly come from the earth's interior heat release, followed by rotation of the Earth's rotation can be generated and gravitational differentiation, chemical reactions, heat release and other rock and mineral crystal. During the formation of the Earth, the total amount of these heat dissipation of heat over the Earth, an enormous heat reserves, so that partial melting of crustal igneous and metamorphic effect. Basic calculation is now out, the planet's core temperature reaches 6000 ° C, temperature of the bottom crust 900-1000 ° C, the surface layer at room temperature (about 15 meters from the ground) about 15 kilometers of the following, the increase of temperature increased with depth. The average temperature of geothermal is about 3 ° C/100 m rate. Geothermal warming rates in different regions are different, close to the average warming rate is called the normal temperature range, higher than the average warming rate of the region, said geothermal anomalies. Geothermal anomaly area is research and development of geothermal resources of the main target. Crustal plate edge, deep fault and the volcanic belt at the other, is obvious geothermal anomalies. Exploration of geothermal resources survey, the general use of surface geothermal survey, drilling and various geophysical methods. Infrared remote sensing technology in exploration in recent years achieved remarkable results. The late 20th century, the exploitation of geothermal resources were mainly shallow, heat storage, and have a fluid (water or artificial irrigation) lead to heat transfer to the surface of the wet geothermal field. Hot dry rock geothermal resources and low-temperature geothermal fields of wetland research development and utilization in the pilot phase. China, rich in geothermal resources, has a long mining history, past the main advantage of hot spring bath treatment. After 1970, in Guangdong Fengshun, Huailai, Tianjin, and Tibet to have been carried out in thermal power generation, building heating, Agricultural greenhouse heating, warm water breeding, irrigation and other aspects Shi Yan Xing Kaifagongzuo, made some achievements.译文：世界上最古老的能源之一。
据测算，地球内部的总热能量，约为全约煤炭储量的1.7亿倍。每年从地球内部经地表散失的热量，相当于1000亿桶石油燃烧产生的热量。
关于地热的来源，有多种假说。一般认为，地热主要来源于地球内部放射性元素蜕变放热能，其次是地球自转产生的旋转能以及重力分异、化学反应，岩矿结晶释放的热能等。
在地球形成过程中，这些热能的总量超过地球散逸的热能，形成巨大的热储量，使地壳局部熔化形成岩浆作用、变质作用。 现已基本测算出，地核的温度达6000°C，地壳底层的温度达900-1000°C，地表常温层（距地面约15米）以下约15公里范围内，地温随深度增加而增高。
地热平均增温率约为3°C/100米。不同地区地热增温率有差异，接近平均增温率的称正常温区，高于平均增温率的地区称地热异常区。
地热异常区是研究、开发地热资源的主要对象。地壳板块边沿，深大断裂及火山分布带等，是明显的地热异常区。
普查勘探地热资源，一般采用地表地热调查、钻探和各种物探方法。近年来红外线遥感技术在勘查中取得显著效果。
20世纪末，地热资源的开采对象，主要是埋藏浅、热储量大、有流体（地下水或人工灌水）把热能传引到地表的湿地热田。干热岩地热资源和低温湿地热田的开发利用处在研究试验阶段。
中国的地热资源丰富，有悠久开采历史，以往主要利用温泉洗浴治病。1970年后，在广东丰顺、河北怀来、天津和西藏等地曾进行地热发电、建筑物采暖、农业温室采暖、温水育种、灌溉等多方面试验性开发工作，取得一定成果。

热能与动力工程是以工程热物理学科为主要理论基础，以内燃机和正在发展中的其它新型动力机械及系统为研究对象，运用工程力学、机械工程学、自动控制、计算机、环境科学、微电子技术等学科的知识和内容，研究如何把燃料的化学能和液体的动能安全、高效、低（或无）污染地转换成动力的基本规律和过程，研究转换过程中的系统和设备的自动控制技术。
随着常规能源的日渐短缺，人类环境保护意识的不断增强，节能、高效、降低或消除污染排放物、发展新能源及其它可再生能源成为本学科的重要任务，在能源、交通运输、汽车、船舶、电力、航空宇航工程、农业工程和环境科学等诸多领域获得越来越广泛的应用，在国民经济各部门发挥着越来越重要的作用。 这方面人才在加强学生基础理论和综合素质教育的同时，加强计算机及自动控制技术的应用，强化专业实践教学，注重全能训练，全面提高自己的实践动手能力和科学研究潜力. 我国能源动力类专业形成于20世纪50年代。
以交通大学为例，1952年院系调整时，当时设在机械系中的动力组就单独成立了动力机械系。由于受当时苏联教育体制的影响，在该学科的发展过程中，专业面曾一度越分越细。
50年代初期只有锅炉、气轮机、内燃机等专业，以后又先后办起制冷专业与风机专业，制冷专业又细分出压缩机，制冷及低温专业。在50年代末又创办了核能专业，在60~70年代有些学校先后设立了工程热物理专业。
这样能源动力学科中的专业就先后包括有锅炉、涡轮机、电厂热能、风机、压缩机、制冷、低温、内燃机、工程热物理，水力机械以及核能工程等11个专业，形成了明显的以产品带教学的基本格局。 热能与动力工程专业中包含的水利水电动力工程专业的前身为水电站动力装置专业。
该专业形成于20世纪50年代。新中国成立以后，随着国家对水患的治理和经济建设的发展，国家设立了华东水利学院、武汉水利水电学院、华北水利水电学院等一些专门的水利院校，1958年起在这些院校和西安交通大学水利系（西安理工大学水电学院的前身）设立了水电站动力装置专业，以满足国家对水电建设人才的迫切需求。
1977年恢复高考招生后，该专业更名为水电站动力设备专业。1984年该专业更名为水利水电动力工程专业，涵盖了原水能动力工程、水电站动力装置、水电站动力设备、水能动力及其自动化、机电排灌工程、水能动力与提水工程等专业，昆明工业学院、成都科技大学等一些院校都设置了该专业。
1998年，按照国家教育部颁布的新的专业目录，水利水电动力工程专业并入热能与动力工程专业，新的热能与动力工程专业包含了原来的热力发动机、流体机械及流体工程、热能工程与动力机械、热能工程、制冷与低温技术、能源工程、工程热物理、水利水电动力、工程冷冻冷藏工程等9个专业。 原创论文网 免费上传出售求购论文，上传毕业设计，考研笔记，论文，课件，策划案等资料赚取现金，去看看吧，有惊喜哦。
