Storage and operating temperatures refer to the ranges over which the connectors can be used when not subjected to mechanical stress. Installation temperature refers to the ranges over which connectors may be installed onto the fi ber and over which connectors can be connected and disconnected from the trnasceiver.2. Typical data are at 25°C.3. Usually, the button of the latching mechanism shall be pressed when disconnecting the fi ber. If the connector is pulled out of the transceiver while the lever is not pressed, the latching mechanism will degrade signifi cantly after the fi rst cycle.Step 2: Putting on the ConnectorPlace the connector on each end of the fi ber, and slide the connector down until the fi ber jacket stops it. The fi ber should protrude no less than 1.5 mm (0.06 in) from the end of the connector.Manually press connectors together. The connectors are secured when top halves latch into the ferrule halves.Step 1: Stripping the FiberThe zip cord structure of the duplex cable permits easy separation of the channels. The channels should be sepa-rated a minimum of 100 mm (4 in) to a maximum of 150 mm (6 in) back from the ends to permit connectoring, pol-ishing and cable end fl exibility.After cutting the cable to the desired length, strip off ap-proximately 7 mm (0.3 in) of the outer jacket with the 16 gauge wire strippers.The separated duplex cable should be stripped to roughly equal lengths on each cable end.Termination Guide for AFBR-4526ZStep-by-Step Plastic Cable Connectoring InstructionsThe following step-by-step guide describes how to termi-nate plastic fi ber optic cable. It is ideal for both fi eld and factory installations. Connectors can be easily installed on cable ends with standard tools such as wire strippers and cutters.Finishing the cable is accomplished with the Avago Tech-nologies AFBR-4594Z Polishing K it, consisting of a three hole polishing fi xture, 600 grit abrasive paper and 3 m pink lapping fi lm. The connector can be used immediately after polishing.The following materials are needed for plastic fi ber termi-nation:1. Plastic optical fi ber cable (Example: HFBR-EUD500Z)2. Wire cutters or scissors3. 16 gauge wire stripper (Example: Ideal Stripmaster type 45-092)4. AFBR-4594Z polishing kit5.Duplex connectors AFBR-4526ZDuring insertion of the fi ber into the connector, make sure that the orientation of the connector is correct (see next fi gure). So you make sure that the optical channels are connected correctly (Tx1 --> Rx2; Tx2 --> Rx1).HingeUntwisted fi berOkNot OkStep 4: FinishingPlace the fl ush connector and polishing fi xture on the dull side of the 3 μm pink lapping fi lm and continue to pol-ish the fi ber in the same fi gure eight pattern for approxi-mately 25 strokes. The fi ber end should be fl at, smooth and clean.Step 3: Trimming and PolishingAny fi ber in excess of 1.5 mm (0.06 in) protruding from the connector end should be cut off with wire cutters or scis-sors.Insert the connector fully into the polishing fi xture with the trimmed fi ber protruding from the bottom of the fi x-ture. This plastic polishing fi xture can be used to polish one or two simplex connectors or one duplex connector.Note: The four dots on the bottom of the polishing fi xture are wear indicators. Replace the polishing fi xture when any dot is no longer visible.Press the polishing tool down on the 600 grit abrasive paper. Polish the fi ber using a fi gure eight pattern until the connector is fl ush with the bottom of the polishing fi xture. Wipe the connector and fi xture with a clean clothor tissue.Polishing kit AFBR-4594ZNote: Use of the pink lapping fi lm fi ne polishing step results in up to 0,5 dB improvement in coupling performance of either a t ransmit t er-receiver link or a bulkhead/splice over a 600 grit polish alone. This fi ne polish is comparable to the Avago Technologies factory polish. The fi ne polishing step may be omitted for short link lengths.For product information and a complete list of distributors, please go to our web site: Avago, Avago Technologies, and the A logo are trademarks of Avago Technologies in the United States and other countries.Data subject to change.

含钛高炉渣制备复合吸附剂及其铬吸附性能

化工进展Chemical Industry and Engineering Progress2024 年第 43 卷第 3 期含钛高炉渣制备复合吸附剂及其铬吸附性能董晓涵，田月，苏毅（昆明理工大学化学工程学院，云南昆明 650000）摘要：Cr(Ⅵ)是一种有害污染物，既污染水环境，也会对人体造成伤害。

本文以工业固废含钛高炉渣为原料，通过酸浸得到浸出渣基体，经壳聚糖改性，制备一种新型GLZ-jcz/CS 复合吸附剂，用来去除废水中的Cr(Ⅵ)。

研究了吸附温度、废水pH 、吸附剂量、Cr(Ⅵ)初始浓度、吸附时间对Cr(Ⅵ)吸附性能的影响。

以Cr(Ⅵ)吸附率为评价指标，确定最优实验条件，并研究了GLZ-jcz/CS 复合吸附剂的再生性能。

采用扫描电子显微镜、傅里叶红外变换光谱仪、X 射线光电子能谱仪、BET 比表面积测试仪对GLZ-jcz/CS 复合吸附剂进行表征，结合吸附动力学模型和吸附等温线模型分析，确定吸附机理。

实验结果表明：当吸附温度为70℃、废水pH=4、吸附剂用量为0.13g 、Cr(Ⅵ)初始浓度为50mg/L 、吸附时间为2h 时，吸附率达到99.8%，吸附容量可以达到67mg/g ，GLZ-jcz/CS 复合吸附剂经过6次洗脱，吸附率仍可达到96%以上，吸附模型符合拟二级动力学模型和Langmuir 吸附等温模型。

In this paper, a new composite adsorbent (GLZ-jcz/CS) was prepared for the removal of Cr(Ⅵ) from wastewater, using industrial solid waste containing titanium blast furnace slag as raw material, and the leached slag matrix was obtained by acid leaching and modified by chitosan. The effects of adsorption temperature, pH of wastewater, adsorbent dosage, initial concentration of Cr(Ⅵ) and adsorption time on the adsorption performance of Cr(Ⅵ) were studied. The optimal experimental conditions were determined using the Cr(Ⅵ) adsorption rate as the evaluation index, and the regeneration performance of GLZ-jcz/CS composite adsorbent was investigated. The GLZ-jcz/CS composite adsorbent was characterized by SEM, FTIR, XPS and BET, combined with adsorption kinetic model and adsorption isotherm model analysis to determine the adsorption mechanism. The experimental results showed that the adsorption rate reached 99.8% and the adsorption capacity could reach 67mg/g when the adsorption temperature was 70℃, the pH of wastewater was 4, the amount of adsorbent was 0.13g, the initial concentration of Cr(Ⅵ) was 50mg/L and the adsorption time was 2h. The GLZ-jcz/CS composite adsorbent can still reach over 96% adsorption after six elutions, and the adsorption model was compounded with the proposed secondary kinetic model研究开发DOI ：10.16085/j.issn.1000-6613.2023-0343收稿日期：2023-03-06；修改稿日期：2023-05-08。

摘要: 弥散强化铜基复合材料具有高温强度、高导电、导热的特性, 具有不可替代的作用。以氧化铝弥散强化铜复合材料为例, 综述其制备工艺、性能分析、强化机理及应用领域, 并预示了其在冶金企业应用的美好前景。
用粉末冶金法制备弥散强化复合材料的基本原理是利用固态金属粉末和增强材料在一定温度和压力下, 金属在增强材料周围被迫流动、扩散, 从而粘接在一起。粉末冶金法的主要工艺过程包括: 制取复合粉末、复合粉末成型、复合粉末烧结。这种方法用于制备颗粒弥散强化铜基体材料, 工
艺成熟, 材料性能也比较好。与内氧化法繁杂的工艺、较多的影响因素相比, 该工艺过程简单, 易于控制。最关键的是用粉末冶金法可以按要求制备指定粒径和含量的弥散强化复合材料。粉末冶金法常与精整、浸油、机加工、热处理以及轧制、热锻等制造工艺紧密结合。 1. 3 内氧化法

基于MODIS数据的洞庭湖生态经济区生态环境质量演变研究

因此，对于区域生态环境的正确认识及评价对我国生态文化建设和生态环境维护意义重大。

卫星遥感技术能快速覆盖大面积区域并及时获取地表信息，已被广泛应用于生态环境评估领域 [2， 3]。

各种各样的遥感指数已被广泛应用于森林、草地、城市和湖泊等生态环境的评估中[4-7]，如归一化植被指数（NDVI）、增强植被指数（EVI）、叶面积指数（LAI）等[8-10]，这些单一遥感指数是地域生态环境评估的关键之一。

然而，由于生态指标影响因素的复杂性和多样性，仅采用一种遥感指数来量化生态系统的状况是不够的[11]，使用多个指标的综合生态指数来量化评估生态状况更具优势，也更加全面。

早在2006年，生态环境部根据生物丰度指数、植被覆盖指数、水网密度指数、土地退化指数和环境质量指数构建的生态环境状态指数（EI），在区域生态环境质量评估方面取得了普遍应用[12]。

但是，综合指数构建普遍面临评价指标提取困难、数据空间精度较低和数据更新慢等问题。

基于卫星遥感信息结合了绿度、湿度、热度、干度的遥感生态指数（RSEI），可以较好地解决上述问题[13]。

RSEI 的指标易于获取且计算简捷，无须人为设定权重和摘要快速城镇化对地区生态环境质量产生重要影响，及时评估生态环境质量变化对城市生态管理和规划具有重要意义。

聚焦超声在面部松弛应用中的不良反应及应对措施陈秀娜;唐静;田艳丽;赵小忠【摘要】目的:探讨聚焦超声技术在面部松弛应用中的不良反应及应对措施.方法:收集临床中应用聚焦超声技术治疗面部松弛所产生的不良反应,分析不良反应产生的原因,并对不良反应采用相应的物理、激光、药物等技术进行修复观察.结果:经过对不良反应成因的分析以及采取各种修复措施,大部分不良反应均有消退或改善.结论:聚焦超声技术是近年来利用超声聚焦技术进行面部年轻化治疗的最新的技术之一.在临床使用的过程中,由于治疗仪器、操作不规范和市场的混乱,造成了一些不良反应.对其成因推断分析,采取积极修复策略,不良反应是可以避免、修复的.【期刊名称】《中国美容医学》【年(卷),期】2019(028)009【总页数】3页(P30-32)【关键词】聚焦超声;面部松弛;不良反应;预防;治疗【作者】陈秀娜;唐静;田艳丽;赵小忠【作者单位】北京小忠丽格医疗美容门诊部北京 100000;北京小忠丽格医疗美容门诊部北京 100000;北京小忠丽格医疗美容门诊部北京 100000;北京小忠丽格医疗美容门诊部北京 100000【正文语种】中文【中图分类】R622面部松弛作为皮肤老化的常见表现之一，其形成原因复杂，包括骨骼萎缩、韧带稳固性减弱、重力作用以及面部表情活动频繁牵拉，导致面部皮肤及颧、颊脂肪垫等软组织松垂，呈现泪沟、鼻唇沟、口角下垂、颏下脂肪堆积等。

随着人们物质生活水平的提升，声光电技术的发展，人们对于面部年轻化治疗的要求越来越趋向于微创或者无创化[1]。

强聚焦超声（Intense focused ultrasound，IFUS）作为一种有效的非侵入性紧肤技术，被评估为一种非爆破再生激光的替代治疗方法。

IFU是声波传递到组织以引起分子间的振动。

这种振动产生的热量大于60℃时，会产生热损伤区并导致胶原蛋白变性。

此外，IFUS引起热损伤不仅在深层真皮，也可发生在面部浅表肌肉腱膜系统（SMAS筋膜层）[2-4]。

新一代测序技术及其在小麦基因组研究中的应用

读书报告一新一代测序技术及其在小麦基因组研究中的应用DNA测序技术是分子生物学研究中最常用的技术。

一代测序技术是20世纪70年代中期由Fred Sanger及其同事首先发明，其基本原理是聚丙烯酰胺凝胶电泳能够把长度只差一个核苷酸的单链DNA分子区分开来。

以此为基础延伸并发展起来的测序技术统称为第一代测序技术，其在分子生物学研究领域发挥过重要作用⑴。

但随着研究的不断深入，传统的测序方法表现出测序测度慢，获取信息量小，大规模测序价格昂贵等缺点，已满足不了深度测序和重复测序等大规模核酸测序的需要，这就促使了新一代测序技术的产生。

新一代测序技术又称为深度测序技术、第二代测序技术，以Roche/454 Genome Sequencer FLX System、lllumina/Solexa Genome Analyzer llx 和ABI SOLID System 等测序平台为标志，其最主要的特征是高通量测序，测序时间和成本都显著降低，因此通常又被称为高通量测序技术［2-3］。

本文对新一代测序技术的基本原理及其在小麦基因组学研究中的应用展开综述。

1新一代测序技术的基本原理新一代测序技术的核心思想是边合成边测序( Sequencing by synthesis SBS)或者边连接边测序(Sequencing by ligation，SBL)，即生成新DNA互补链时，加入的dNTP通过酶促级联反应催化底物激发出荧光，或者直接加入被荧光标记的dNTP或半简并引物，在合成或连接生成互补链时，释放出荧光信号。

通过捕获光信号并转化为一个测序峰值，获得互补链序列信息⑷。

下面分别对新一代测序平台Roche (454) GS FLX sequencer、Illumina genome analyzer、Applied Biosystems SOLiD sequencer 等的测序原理进行简述。

1.1 Roche (454) GS FLX seque ncer在Roche/454测序平台中主要应用的是焦磷酸测序(pyrosequencing)技术⑸。
