请注意,以上内容仅为引言部分,并非完整文章稿件。
2. 正文:2.1 叔丁基过氧化氢介绍叔丁基过氧化氢是一种有机过氧化物,其化学式为C4H10O2。
它是一种无色液体,在常温下稳定性较高。
叔丁基过氧化氢常用作发泡剂、引爆剂和漂白剂等工业应用中。
2.2 密度的概念和计算方法密度是指物质单位体积的质量,常用符号为ρ(rho)。
密度可以通过以下公式计算得到:密度= 质量/ 体积其中,质量以克为单位,体积以立方厘米或立方米为单位。
2.3 影响叔丁基过氧化氢密度的因素有几个因素可能会影响叔丁基过氧化氢的密度。
首先是温度,当温度升高时,分子间的间隔增大,导致单位体积内分子数减少,从而使密度降低。
其次是压力,根据物态方程PV=nRT(P表示压力,V表示体积,n表示摩尔数,R为理想气体常量,T表示温度),若温度和摩尔数保持不变,则压力变大会导致体积减小,进而密度增加。
还有一些其他因素如溶质浓度、杂质等也可能对叔丁基过氧化氢的密度产生一定的影响。
文章至此为止,后续待添加。
3. 解释说明:3.1 密度的意义和重要性:密度是物质的一种物理特性,用于描述物质的紧密程度或物质在单位体积内所具有的质量。
它是指单位体积的物质质量,通常以克/立方厘米(g/cm³)或千克/立方米(kg/m³)为单位。

数字电压表电路ICL7107ICL7107 安装电压表头时的一些要点:按照测量=±199.9mV 来说明。
1.辨认引脚:芯片的第一脚,是正放芯片,面对型号字符,然后,在芯片的左下方为第一脚。
也可以把芯片的缺口朝左放置,左下角也就是第一脚了。
许多厂家会在第一脚旁边打上一个小圆点作为标记。
知道了第一脚之后,按照反时针方向去走,依次是第2 至第40 引脚。
(1 脚与40 脚遥遥相对)。
2.牢记关键点的电压:芯片第一脚是供电,正确电压是DC5V 。
第36 脚是基准电压,正确数值是100mV,第26 引脚是负电源引脚,正确电压数值是负的,在-3V 至-5V 都认为正常,但是不能是正电压,也不能是零电压。
芯片第31 引脚是信号输入引脚,可以输入±199.9mV 的电压。
在一开始,可以把它接地,造成“0”信号输入,以方便测试。
3.注意芯片27,28,29 引脚的元件数值,它们是0.22uF,47K,0.47uF 阻容网络,这三个元件属于芯片工作的积分网络,不能使用磁片电容。
芯片的33 和34 脚接的104 电容也不能使用磁片电容。
4.注意接地引脚:芯片的电源地是21 脚,模拟地是32 脚,信号地是30 脚,基准地是35 脚,通常使用情况下,这4 个引脚都接地,在一些有特殊要求的应用中(例如测量电阻或者比例测量),30 脚或35 脚就可能不接地而是按照需要接到其他电压上。
--本文不讨论特殊要求应用。
5.负电压产生电路:负电压电源可以从电路外部直接使用7905 等芯片来提供,但是这要求供电需要正负电源,通常采用简单方法,利用一个+5V 供电就可以解决问题。
比较常用的方法是利用ICL7660 或者NE555 等电路来得到,这样需要增加硬件成本。
我们常用一只NPN 三极管,两只电阻,一个电感来进行信号放大,把芯片38 脚的振荡信号串接一个20K -56K 的电阻连接到三极管“B”极,在三极管“C”极串接一个电阻(为了保护)和一个电感(提高交流放大倍数),在正常工作时,三极管的“C”极电压为2.4V -2.8V为最好。

AC Current ProbeModels SR701 and SR704User ManualDESCRIPTIONThe SR701/SR704 AC Current Probes (Catalog #2116.29 and #2116.30) are designed for use in industrial environments. The ergonomic design allows them to easily attach to cables or small bus bars. The “circular” jaws guarantee a very good accuracy and low phase shift. The probes have a measurement range up to 1000 Arms and are compatible with any AC ammeter, multimeter, or other current measurement instrument with an input impedance lower than 5 Ω. To achieve the stated accuracy, use the SR701/SR704 with an ammeter having an accuracy of 0.75 % or better.WARNINGThese safety warnings are provided to ensure the safety of personnel and proper operation of the instrument. Read the instruction manual completely and follow all the safety information before attempting to use or service this instrument.• Use caution on any circuit: potentially high voltages and currents may be present and may pose a shock hazard.• Do not use the probe if damaged. Always connect the current probe to the measuring device before it is connected around the conductor• Do not use on non-insulated conductor with a potential to ground greater than 600 V CAT III pollution 2.Use extreme caution when clamping around bare conductors or bus bars.• Before each use, inspect the probe; look for cracks in housing or output cable insulation.• Do not use clamp in wet environment or in locations that hazardous gases exist.• Do not use the probe anywhere beyond the tactile barrier.INTERNATIONAL ELECTRICAL SYMBOLSThis symbol signifies that the current probe is protected by double or reinforcedinsulation. Use only factory-specified replacement parts when servicing the instrument.This symbol signifies CAUTION! and requests that the user refer to the user manualbefore using the instrument.This symbol signifies that this is a type A current sensor and that application near andremoval from HAZARDOUS LIVE conductors is permitted.DEFINITION OF MEASUREMENT CATEGORIESCAT IV: For measurements performed at the primary electrical supply (< 1000 V), such as on primary overcurrent protection devices, ripple control units, or meters.CAT III:For measurements performed in the building installation at the distribution level, such as hardwired equipment in fixed installation or circuit breakers.CAT II: For measurements performed on circuits directly connected to the electrical distribution system, such as measurements on household appliances or portabletools.RECEIVING YOUR SHIPMENTUpon receiving your shipment, make sure that the contents are consistent with the packing list.

Select the appropriate current range (2 A AC range). Clamp the probe around the conductor to be tested with the arrow pointed toward the load. If the reading is less than 200 mA, select the lower range until you obtain the best resolution. Read the value display on the DMM and multiply it by the probe ratio (1000/1). (If reading = 0.659 A, the current flowing through the probe is 0.659 A x 1000 = 659 A AC ).•For best accuracy, avoid if possible, the proximity of other conductors which may createnoise.Tips For Making Precise Measurements• When using a current probe with a meter, please select the range that provides the best resolution. Failure to do this may result in measurement errors.• Make sure that probe jaw mating surfaces are free of dust and contamination.Contaminants cause air gaps between the jaws, increasing the phase shift betweenprimary and secondary. It is very critical for power measurement.MAINTENANCEWarning• For maintenance use only original replacement parts.• To avoid electrical shock, do not attempt to perform any service on the device unless you are qualified to do so.• To avoid electrical shock and/or damage to the instrument, do not allow water or other foreign agents to come into contact with the probe.CleaningTo ensure optimum performance, it is important to keep the probe jaw mating surfaces clean at all times. Failure to do so may result in error in readings. To clean the probe jaws, use very fine sand paper (fine 600) to avoid scratching the jaw, and then gently clean with a soft, oiled cloth.

新抚钢拟转让70%股权建龙有意介入
对吉林省通化钢铁集团有限责任公司的重组尚未全面启动,民营钢铁巨头建龙钢铁控股有限公司(下称“建龙钢铁”)又迫不及待地把触角伸向了辽宁省。
《第一财经日报》昨天获悉,利用近期辽宁省抚顺新抚钢有限责任公司(下称“新抚钢”)转制的机会,建龙钢铁又想将辽宁省的一个钢厂收入囊中。
如果此举成行,建龙钢铁将在东北三省构建起自己的钢铁“金三角”,规模的扩张步伐加速。
新抚钢转制
《第一财经日报》从抚顺市产权交易中心获悉,新抚钢有限责任公司已经进入了挂牌公示阶段。
抚顺市国有资产管理委员会改制办的张先生昨天在接受《第一财经日报》电话采访时透露,挂牌公示的时间为9月1日到28日。
而抚顺市产权交易中心李庆文主任则对记者介绍,如果登记受让方只有一家,将通过协议转让的方式转让70%的股权;如果登记受让方不止一家,则由抚顺市国有资产管理委员会和产权交易中心共同讨论到底是采取竞价拍卖的方式还是招投标的方式。
根据挂牌公示的信息显示,截至今年6月30日,新抚钢的资产总值为53亿元,负债总值37亿元,净资产为15.8亿元。
建龙有意介入
抚顺市产权交易中心的一位内部人士对记者透露,事实上目前为止,还没有一个有意受让方正式登记,一些有意登记的企业由于达不到受让的要求而无法登记。
因为根据产权转让的规定,受让方必须具有与钢铁行业相关的生产、管理的经验、顺畅的销售渠道或具有一定的投资和营销企业的经验。
受让方的出资额不得高于其净资产的50%,即具有净资产人民币22.2亿元以上。

“虽然目前还没有一家企业正式登记,但建龙钢铁已经与我们接触很多次了。
”该人士透露。
新抚钢始建于1958年6月,是抚顺市国有资产管理委员会全资拥有的国有钢铁企业。
此次抚顺市国资委打算转让70%的股权,转让底价为人民币*****.213万元。
新抚钢销售部的严先生告诉记者,目前除了刚刚完成合并挂牌的鞍本集团外,辽宁比较有规模的钢厂就是去年刚刚完成兼并重组的东北特钢和现在正要进行产权转让的新抚钢了。
新抚钢具有230万吨的年产能。
新抚钢办公室的一位不愿透露姓名的工作人员告诉记者,由于现在新抚钢已经在挂牌公示阶段,今后的产品结构方向恐怕要跟随股权受让方一起调整了。
相关背景
填补“辽宁空白”
建龙钢铁是国内规模较大的民营钢铁企业,经过5年的发展,
在国内收购了一系列的国有钢铁企业,建龙旗下的钢铁企业已经囊括了唐山建龙、宁波建龙、承德建龙、吉林建龙和黑龙江建龙。
可以发现,在东北三省,建龙钢铁目前只有辽宁省没有“扎根”,而抚顺拥有丰富的矿产资源,而且物流方便,新抚钢本身位于抚顺市望花区西部工业区,北临沈大高速公路,南与国铁相接,交通十分便利。
由于国内原材料、资源、运输上的紧张,目前中国钢铁企业只有规模扩大,才能在竞争中节约尽可能多的成本而取胜,做大做强。
国家新颁布的《钢铁产业政策》也鼓励钢厂之间的兼并重组。
上个月,《第一财经日报》曾报道,建龙集团旗下的吉林建龙公司,还将携手吉林省铁合金集团有限公司,对吉林省最大的国有钢铁企业――通化钢铁进行资产重组。
而建龙一直寄很大希望的宁波建龙项目一直不是很顺利,前一阶段刚刚通过重组方案。
但如果东北的这两个项目能够顺利纳入建龙的手中,通化钢铁和新抚钢两个钢厂加起来的产能正好差不多等于将来宁波建龙计划的600万吨钢产能,加上年产200万吨的黑龙江建龙钢铁有限公司,建龙钢铁在东北将可构建一个非常好的钢铁“金三角”。
