Here are the important components on the board:(1) - Terminal Block for Power & Output connections(2) - Single Turn Potentiometer to adjust Emissivity in tenths (0.x_)(3) - Single Turn Potentiometer to adjust Emissivity in hundreds (0._x)(4) -Slide switch to select between real time (Normal Operation) and alarm set point(5) - Alarm set point adjust, P4(6) - Sensor Head connection(7) - Input Zero adjust, P3(8) - Input Span adjust, P2(9) - Output Zero adjust, P5(10) - Output Span adjust, P6Figure 3-1. Main PC Board3.2Ambient TemperatureThe Sensing head can operate in an ambient temperature of 0 to 70°C (32to 158°F). The Sensing head in the high temperature model (-HT) can operate in an ambient temperature of 0 to 85°C (32 to 185°F) without any cooling required. The Sensing head can operate up to 200°C (392°F) using the water cool jacket accessory OS100-WC (See Fig. 3-6).There is a warm up period of 3 minutes after power up. After the warm up period, temperature measurement can be made.When the ambient temperature around the sensor head changes abruptly,the sensor head goes through thermal shock. It takes a certain amount of time for the sensor head to stabilize to the new ambient temperature. For example, it takes about 30 minutes for the sensor head to stabilize going from 25°C to 50°C (77 to 122°F) ambient temperature.The sensor head dimensions are shown in Fig. 3-2.Figure 3-2. Sensor Housing3-23-33.3Atmospheric QualityEnvironments with smoke, dust, and fumes dirty up the optical lens, and cause erroneous temperature readings. To keep the surface of the optical lens clean, the air purge collar accessory is recommended, OS100-AP , See Fig. 3-7.3.4Measuring TemperatureBefore starting to measure temperature, make sure that the following check list is met:ߜ The power and analog output connections are made (Fig. 2-1).ߜThe sensor head is connected to the main unit.ߜThe slide switch (SW1) on the main board is set to real time (Fig. 3-1).ߜThe target is larger than the optical field of view of the sensor head (Fig. 3-3).ߜThe emissivity adjustment on the main board is set properly (Fig. 3-1).ߜThe output load is within the product specification.On OS102 transmitters, follow these additional steps:ߜ The temperature display is set to °F or °C (Fig. 3-4)ߜ For 4-20mA output models, make sure an output load is added, ie. 250ohms.Figure 3-3.

morse势参数
Morse势参数1. 引言Morse势是一种常见的量子力学势能函数，它在原子物理、分子物理、固体物理等领域有广泛的应用。
Morse势参数是描述Morse势的重要指标，对于研究分子结构、光谱数据以及化学反应动力学等具有重要意义。
本文将介绍Morse势的基本概念和数学表达式，并详细阐述Morse势参数的物理意义和计算方法。
同时，还将探讨Morse势在不同领域中的应用以及未来的发展方向。
2. Morse势简介Morse势是由美国物理学家Philip M. Morse于1929年提出的一种模型，用于描述分子中原子之间相互作用的势能函数。
它是一种解析形式非常简洁、易于计算和处理的函数。
Morse势可以表示为以下形式：V(r)=D e(1−e−a(r−r e))2其中，V(r)表示距离为r时系统中两个原子之间的相互作用势能；D e表示最小能量点对应的深度；r e表示最小能量点对应的平衡距离；a是一个与分子特性相关的常数。
Morse势具有以下特点：•在r=r e处存在一个极小值点，对应于原子之间的平衡距离；•势能在r=r e附近呈现抛物线形状，越远离平衡位置，势能增加得越慢；•势能在r=∞时趋于零。
3. Morse势参数Morse势参数是指用来描述Morse势形状和性质的一组物理量。
常见的Morse势参数包括：3.1. 势阱深度(D e)势阱深度是指最低点对应的能量值，表示两个原子之间相互作用的最强力。

本特利3500中文说明介绍模板之欧阳育创编
TSI系统调试基本知识本内容将围绕大多数电厂中广泛使用的美国本特利（BENTLY）公司生产的振动检测系统3500为模版，全面讲述系统安装、组态、调试过程及调试中常见问题的处理。
第一节 TSI系统硬件基本知识3500系统能提供连续、在线监测功能，适用于机械保护应用，并为早期识别机械故障提供重要的信息。
该系统高度模块系统的工作流程是：从现场取得的传感器输入信号提供给3500监测器框架内的监测器和键相位通道，数据被采集后，与报警点比较并从监测器框架送到一个地方或多个地方处理。
3500框架中模件的共同特征是带电插拔和内部、外部接线端子。
任何主模件（安装在3500框架前端）能够在系统供电状态中拆除和更换而不影响不相关模块的工作，如果框架有两个电源，插拔其中一块电源不会影响3500框架的工作。
外部端子使用多芯电缆（每个模块一根线）把输入\输出模块与终端连接起来，这些终端设备使得在紧密空间内把多条线与框架连接起来变的非常容易，内部端子则用于把传感器与输入\输出模块直接连接起来。
外部端子块一般不能与内部端子输入/输出模块一起使用。
1、3500/05系统框架3500框架用于安装所有的监测器模块和框架电源。
它为3500各个框架之间的互相通讯提供背板通讯，并为每个模块提供所要求的电源。
3500框架有两种尺寸：1 全尺寸框架——19英寸EIA框架，有14个可用模块插槽2 迷你型框架——12英寸框架，有7个可用模块插槽电源和框架接口模块必须安装于最左边的两个插槽中。
其余14个框架位置（对与迷你型框架来说是其余7个位置）可以安装任何模块。
2、3500/15电源模块3500 电源是半高度模块，必须安装在框架左边特殊设计的槽口内。
3500 框架可装有一个或两个电源(交流或直流的任意组合)。
其中任何一个电源都可给整个框架供电。
如果安装两个电源，第二个电源可做为第一个电源的备份。
当安装两个电源时，上边的电源作为主电源，下边的电源作为备用电源，只要装有一个电源，拆除或安装第二个电源模块将不影响框架的运行。

马尔文粒度MS3000资料 v5
理解粒径分布 › 根据占比类型的不同，可以有体积分布（该粒径的颗 粒体积占样品总体积的百分比），数量分布（该粒径 的颗粒数量占样品总颗粒数量的百分比）， 或者其 他不同的分布方式。 › 基于仪器的设计原理，体积分布结果能最好的反应 Mastersizer 3000对样品的敏感性，所以通常使用体 积分布结果。同时，在假设颗粒为实心球体的前提下， 也可通过数学运算推导出长度分布，表面积分布及数 量分布结果。 › 关于不同粒径分布的区别：
光电二极管是二极管的一种，工作在反向偏压状态。利用光电 效应，光子冲击二极管激发出电子和带正电的空穴，从而产生 光电流。
无光照时，处于截止状态，在反向偏压的作用下，只有少数载 流子穿过势垒区，形成微弱的反向电流，称为暗电流。 有光照时，在光子辐射下，P/N区载流子（电子和空穴）浓度均 大大增加，在反向偏压和内电场作用下，穿过势垒区，形成光 电流，且入射光子越多，光电流越大，即光电流与光强成正比 关系。因此，通过测量此时电流大小可得到该角度检测器上的 光强大小。

【摘要】知道玄度这个品牌,还是四年前的事了。
记得当时成都新鸿路上开了一家叫“玄度音响行”的音箱专卖店,我每天上下班都要路过那里,日复一日,这个名字就留在脑子里。
跟大部分发烧友一样,我对音响店的兴趣很浓,时常用回家之便进去看看,就这样初步认识了玄度。
现在回想起来,当年只经营单一品牌的音响专卖店好象没有几家,而眼下音响专卖店似乎正成为一种潮流,如此看来,深圳的玄度公司真算得上是具有超前营销意识的厂家。
只可异,后来由于某种原因,玄度音箱一度在成都市场沉寂了一段时间。
现在,这个久违的品牌终于又出现我的面前,并有一款音箱将要接受测评。
它便是玄度2000年的新品:名士三号。
