Answer: Yeah. It’s very important for two reasons. For the country, it’s a time to remember our cultural origin and our historical past. The whole country celebrates our root and it’s very inspiring. We become so proud of our past. I guess that’s why festivals are important. For the individual, festivals give us a chance for relaxation as we often have a few days off. It’s a time of fun, meeting friends, entertainment. So after that we feel like a new man. In a sense, holidays restore our balance between work and leisure. That’s also why we need festivals for China. Q: Would you agree that the original significance of festival is often lost today? 构思: 节日的初衷: 庆祝传统, 承上启下, 结束也是开始 现在的节日: 人们繁忙, 感觉不到开始和结束的意义, 过完节,马上就再次投入到工作中, 有些单位甚至连节假日都加班. 人们也不在那么感动传统,倒是好好的利用节日放松了一下,

G 试验和 GM 试验检测原理和临床应用

G 试验和 GM 试验检测原理和临床应用 首都医科大学附属北京安贞医院左大鹏 G 试验和 GM 试验的检测原理和临床应用。目前我们国际合国内都对侵袭性真菌病的诊断制订了标准，其中有权威的是欧洲癌症研究和治疗组织暨侵袭性真菌病感染协作组，我们简称叫欧洲标准所制订的一个标准。这个标准它对侵袭性真菌病它分了三个不同的诊断层次。一个叫确诊，一个叫临床诊断，一个叫疑诊。 我们国家的很多的专业委员会也都根据欧洲标准就结合我们国家和专业的特点制订了我们国家各个专业的诊断标准。比如说中国侵袭性真菌感染工作组在 2010 年第 3 次修订的血液病和恶性肿瘤患者侵袭性真菌感染的诊断，诊断标准和治疗原则，这第 3 次修订，第一次是 2006 ，第二次 2008 ， 2010 年是第 3 次修订了。这应该是血液里的肿瘤病人所用的一个标准。中华医学会器官移植学分会制订的实体器官移植患者侵袭性真菌感染的诊断和治疗指南。这可能是实体器官移植的这个方面的诊断标准。中华医学会儿科学会，中华医学会呼吸病学会，中华医学会急诊协会，中华妇产科学会也都根据自己的专业制订了的相应的侵袭性真菌感染的诊断和治疗指南。这作为我们从事这些方面的医务工作者所遵循的一个标准。 那我们看不管是国内和国际现在都采用这样一种方式。首先要看这个病人有没有宿主因素，它是不是容易发生侵袭性真菌，真菌感染的高危人群，你要是这样的，你要一个健康人这就不具备了，起码有一些原因它容易得侵袭性真菌感染要具备这样一个高危因素。第二它有临床表现，当然包括临床症状和影像学，比如说胸片， CT ，颅片等等。还有有微声学的检查，还有一个病理学检查，如果你只有宿主因素有临床表现我们叫做拟诊，不叫疑诊，疑似诊断。如果说你在这两个基础上又多了一条有微生物学证据，或者是培养的，或者是非培养的技术凡是证明他有真菌性感染的这种可能性就要临床诊断，临床诊断。如果再加上从肺的组织，从脏器的组织取出病理来确定，那叫确诊。所以侵袭性真菌感染根据宿主因素临床表现微生物学真菌，组织病理的结果，可以把它分成为拟诊，临床诊断跟确诊三个层次。确诊了当然就已经是确定了，治疗起来更有针对性。临床诊断基本是确定了，大方向也没有问题。拟诊是不能，不叫，就是说我们只能是一种预防性的治疗，或者是一种抢先的有干预的治疗，还不能说它一定有真菌感染。比如说我们高度怀疑，高度怀疑。 不管我们前面讲了，就是你要做到临床诊断你就必须有微生物学的真菌。在欧洲标准和我们国家各个专业把脑脊液能够找到隐球菌抗原这个阳性结果作为真菌性脑膜炎或者叫播散性真菌隐球菌病的一个确诊的依据。这时候确诊就不需要组织学了，它只要脑脊液里面找到隐球菌的抗原就确诊。血清的 1 、 3 β D 葡聚糖的检测我们称为 G 试验和这个曲霉菌的半乳甘露聚糖的 GM 试验，那就这个 G 试验和 GM 试验作为临床诊断侵袭性真菌病的依据。当然它不是确诊，它是临床诊断。 我们来看这是中华内科杂志 2007 年中国，中华这个重症协会所制定的关于重症患者侵袭性真菌感染的诊断语言，它在这个微生物学检查里面它要求所有的标本应该是新鲜的，

鲎试剂实验方法

鲎试剂实验方法 鲎试剂按实验方法可分为：凝胶法、动态浊度法鲎试剂、终点浊度法鲎试剂、动态显色法鲎试剂、终点显色法鲎试剂。 凝胶法系通过鲎试剂与内毒素产生凝集反应的原理来定性检测或半定量内毒素的方法。凝胶法是通过观察有无凝胶形成作为反应的终点。此法操作比较简单，经济，不需要专用测定设备，可以进行定性或半定量测定。 凝胶法鲎试剂常见规格为0.1ml/支或0.2ml/支的单个测试或0.5ml/支至5.2ml/瓶的真空封口西林瓶装的多个测试。使用时一般应加细菌内毒素检查用水复溶后使用。厦门市鲎试剂实验厂有限公司的真空封口试管凝胶法鲎试剂是把鲎试剂直接灌装在试管中，在真空中压盖封口的新产品。使用时直接用样品溶解鲎试剂，不会割伤手，更加简单方便安全。 特异性鲎试剂，即弃G因子鲎试剂，是厦门市鲎试剂实验厂有限公司国内首创的产品，它专一对内毒素起反应，避免了G因子旁路的干扰，使检测结果更加可靠，在药检和临床检验方面是不可或缺的理想检测试剂。目前厦门市鲎试剂实验厂有限公司提供的各种内毒素检测鲎试剂均为特异性鲎试剂，都能对抗葡聚糖的干扰，只对内毒素起反应。因此不列为独立品种。 动态浊度法鲎试剂、终点浊度法鲎试剂、动态显色法鲎试剂、终点显色法鲎试剂，这四种方法都是定量检测内毒素的。这几种定量法鲎试剂统称光度法鲎试剂。 根据检测原理，终点浊度法和动态浊度法都属于浊度法。浊度法系利用检测鲎试剂与内毒素反应过程中的浊度变化而测定内毒素含量的方法。终点浊度法未见商品化产品。动态浊度法（又称动态比浊法）是检测反应混合物的浊度上升某一预先设定的吸光度所需要的反应时间，或是检测浊度增加速度的方法。 动态浊度法的特点为：1. 能准确定量。2.检测范围宽，可达4个数量级。3.灵敏度高达0.005EU/ml。4. 操作简便，系统自动检测分析，一步即成。5. 经济实用，试剂样品需要量少，可降至50μL。6. 和微生物检测系统Elx808（配套IU）及专用软件TALgent使用，一次可同时检测多达96个样品。 终点显色法和动态显色法都是属于显色基质法。显色基质法系利用鲎试剂与内毒素反应过程中产生的凝固酶使特定底物显色释放出的呈色团的多少而测定内毒素含量的方法，根据产物颜色判断内毒素浓度，又称为比色法。显色基质法由于不依赖凝固蛋白形成凝胶，抗干扰能力强，特别适用于生物制品（蛋白、疫苗等）和临床样品（黄疸、血液、尿液）的细菌内毒素检测。 终点显色法是目前反应时间最短的鲎试验法，只需要16分钟就能得出结果。而且可以偶氮化染色剂，避开某些有色检品自身颜色对鲎试验的干扰。终点显色法不需要特殊的检测仪器就能准确定量。 动态显色法鲎试剂兼有动态浊度法和终点显色法鲎试剂的优点，抗干扰能力强，使用简单方便，检测范围宽，灵敏度高达0.005EU/ml, 是目前世界上最好的鲎试剂。但是价格较高。 如果您仅需要检测样品的内毒素限量，可以选择凝胶法鲎试剂，通过确定内毒素限值及最大有效稀释倍数，做样品的干扰试验从而确定使用的鲎试剂的灵敏度。如果您需要定量测定样品中内毒素含量则应选择显色基质鲎试剂盒或动态浊度法鲎试剂。日常检测量不大时，可以选择终点显色法鲎试剂，用普通的分光光

电动汽车充电技术国内外研究现况及发展趋势

电动汽车充电技术国内外研究现况及发展趋势 班级： 姓名： 学号：

摘要：对国内外电动汽车、电动汽车充电技术及规划布局等方面现状进行了研究，并对电动汽车充电需求进行了分析。介绍了国内外电动汽车充电设施的发展状况，对未来我国电动汽车发展前景进行了初步研究，提出积极推动电动汽车充电设施建设应是电网企业义不容辞的责任以及未来发展机遇。 关键词：电动汽车充电技术研究现状发展趋势 1.前言 电动汽车是全部或部分由电能驱动电机作为动力系统的汽车，按照目前技术的发展方向或者车辆驱动原理，可划分为纯电动汽车、混合动力汽车和燃料电池电动汽车三种类型。近年来，我国电动汽车行业取得了快速发展，攻克了一系列关键技术难题，在部分领域已实现了与日美欧等国同步发展。目前我国发展电动汽车已具有消费市场规模大、制造成本低、技术取得局部突破、资源保障能力强的四大优势。在技术突破和政策扶持的双重刺激下，我国电动汽车已处于市场引爆的临界点，预计未来两年电动汽车的市场规模和生产规模将迅速扩大，电动汽车将进入快速成长期。电动汽车充电设施是电动汽车产业链的重要组成部分，在电动汽车产业发展的同时还应该充分考虑充电设施的发展。 1 电动汽车充电的基本方式 目前常用的电动汽车充电方式有慢充、快充和快换三种： (1) 慢充方式。慢充一般以较小交流电流进行充电，充电时间通常为6～10 h，慢充方式一般利用晚间进行充电，充电时可以采用晚间低谷电价，有利于降低充电成本，但是难以满足使用者紧急或者长距离行驶需求。慢充一般采用单相220V/16A 交流电源，通过车载充电器对电动汽车进行充电，车载充电器可采用国标三口插座，基本不存在接口标准的问题。电动汽车慢充一般通过充电桩进行。 (2) 快充方式。快充又称应急充电，以较大直流电流在20 min 至1 h 内，为电动汽车提供短时充电服务，快充方式可以解决续航里程不足时电能补给问题，但是对电池寿命有影响，因电流较大，对技术、安全性要求也较高。快充的特点是高电压、大电流，充电时间短（约1 h）。目前，这种充电方式的充电插口的针脚定义、电压、电流值、控制协议等均没有国家标准，也没有国际标准，已投入使用的充电机和电动车电池充电插口均由各生产厂家自定，世界各国都在积极争夺标准的制订权，各大电动汽车厂家也纷纷抢先投放产品，抢占市场、提高占有率，试图使多数充电站不得不采用其充电设备，从而成为事实标准。快充方式主要在充电站中进行。 (3) 快换方式。快换则是通过直接更换车载电池的方式补充电能，换电时间与燃油汽车加油时间相近，大约需要5～10 min。快换方式最为便捷，但是需要电动汽车和车载电池实现标准化，而且快换过程中需要专业人员进行操作。快换可以在充电站也可在专用电池更换站完成。这种方式的优点是电动车电池不需现场充电，更换电池时间较短，但要求电池的外形、容量等参数完全统一，同时，还要求电动汽车的构造设计能满足更换电池的方便性、快捷性。 2 国外电动汽车充电设施发展状况

鲎试验微生物检测系统和普通酶标仪有什么区别

鲎试验微生物快速检测系统和普通酶标仪有什么区别？ 利用鲎试验进行细菌内毒素和真菌（1,3）-β-D-葡聚糖定量检测常用动态浊度法进行。动态浊度法是动力学检测法的一种，需要能进行动力学反应的光学检测仪器（kinetic reader）。鲎试验微生物快速检测系统Elx808(配套IU)主机为动态微板检测仪（kinetics microplate reader），具有专利4-Zone TM温控装置，温度控制精确，温控可达50℃，为细菌内毒素和真菌（1,3）-β-D-葡聚糖定量检测鲎试验最适合的检测仪器。 由于插试管的动力学检测仪器（kinetic tube reader）无法标准化及批量化，国际上进行细菌内毒素检测时比较少用，而广泛使用配备微板的动态微板检测仪（kinetic microplate reader）。 动态微板检测仪（Kinetic microplate reader）和普通酶标仪有本质上的区别。普通酶标仪不能做动力学检测，不带有温控系统，比较适合简单酶标实验，因此国内常把microplate reader翻译成酶标仪，这个名字会误导以为微板检测只能叫酶标仪。 鲎试验微生物快速检测系统Elx808（配套IU）的检测容器为国际标准化96孔微板，最小化检测容器直径及厚度差异的影响；可多至12孔同时加样，96个样品同时检测，另可配备多道移液器或自动化操作系统，提高工作效率，消除人为误差，微量操作，减少试剂用量。我司在该系统配备的除热原除葡聚糖耗材为可拆式96孔微板，有8孔独立包装板条，减少耗材浪费合适各种实验使用。 独特的设计使我司鲎试验微生物快速检测系统的性能优于插试管的内毒素检测仪，封闭的检测空间，升温速度快，孔间温度均匀一致。温控设置精度可达±0.1℃。 鲎试验微生物快速检测系统Elx808（配套IU）配备专业细菌内毒素和真菌（1,3）-β-D-葡聚糖检测软件，为国际上最权威的细菌内毒素和真菌（1,3）-β-D-葡聚糖检测仪器，长期以来被国际上主要的鲎试剂生产厂家推荐用于细菌内毒素检测，见以下网站： 1.

[精华]鲎试剂试验方法

[精华]鲎试剂试验方法 鲎试剂实验方法 鲎试剂按实验方法可分为:凝胶法、动态浊度法鲎试剂、终点浊度法鲎试剂、动态显色法鲎试剂、终点显色法鲎试剂。 凝胶法系通过鲎试剂与内毒素产生凝集反应的原理来定性检测或半定量内毒素的方法。凝胶法是通过观察有无凝胶形成作为反应的终点。此法操作比较简单，经济，不需要专用测定设备，可以进行定性或半定量测定。 凝胶法鲎试剂常见规格为0.1ml/支或0.2ml/支的单个测试或0.5ml/支至 5.2ml/瓶的真空封口西林瓶装的多个测试。使用时一般应加细菌内毒素检查用水复溶后使用。厦门市鲎试剂实验厂有限公司的真空封口试管凝胶法鲎试剂是把鲎试剂直接灌装在试管中，在真空中压盖封口的新产品。使用时直接用样品溶解鲎试剂，不会割伤手，更加简单方便安全。 特异性鲎试剂，即弃G因子鲎试剂，是厦门市鲎试剂实验厂有限公司国内首创的产品，它专一对内毒素起反应，避免了G因子旁路的干扰，使检测结果更加可靠，在药检和临床检验方面是不可或缺的理想检测试剂。目前厦门市鲎试剂实验厂有限公司提供的各种内毒素检测鲎试剂均为特异性鲎试剂，都能对抗葡聚糖的干扰，只对内毒素起反应。因此不列为独立品种。 动态浊度法鲎试剂、终点浊度法鲎试剂、动态显色法鲎试剂、终点显色法鲎试剂，这四种方法都是定量检测内毒素的。这几种定量法鲎试剂统称光度法鲎试剂。 根据检测原理，终点浊度法和动态浊度法都属于浊度法。浊度法系利用检测鲎试剂与内毒素反应过程中的浊度变化而测定内毒素含量的方法。终点浊度法未见商品化产品。动态浊度法(又称动态比浊法)是检测反应混合物的浊度上升某一预先设定的吸光度所需要的反应时间，或是检测浊度增加速度的方法。

电动汽车国内外现状

关于电动汽车国内外现状的研究 化学系 0907401班贺绍飞 [摘要] 文章论述了电动汽车的发展过程和技术现状（主要是能源系统(电池技术)的现状），以及国内外电动汽车的发展现状和电动汽车的优缺点，同时对电动汽车技术的发展趋势进行了分析。 [关键词] 电动汽车；能源系统；优缺点 1引言 世界汽车工业的迅速发展，推动了世界经济交通能源工业等各方面的发展，却也带来了很大弊端；燃油造成的大气污染日益严重。加之目前世界石油资源日益枯竭。因此，百余年来作为人类最主要交通工具之一的汽车的动力系统以燃油为根本的地位开始发生动摇，而电动汽车这一无污染且能源又可多样化配置的动力方案已引起世人的普遍关注。 电动汽车的诞生距今已有120年的历史，但长期以来，一直无法解决电池高功率容量及充电等方面的问题，只好让燃油汽车垄断市场。进入本世纪80年代末，节能与环保问题已成为世界各国所关注的主要社会发展问题，进而电动汽车的研究又成为许多发达国家及各大汽车公司的重要发展项目。由于近年来高新技术的飞跃发展，新型高能电池不断开发利用，以及燃料电池的应用成功，使电动汽车进入了一个新的发展时期，开始步入实用化阶段。可以预计，21世纪将是电动汽车风靡全球的新时代。 2电动汽车的发展过程 电动汽车和内燃机汽车同样历史悠久，早在世界第一辆燃油汽车诞生于1886年之前，1881年在法国巴黎街上就出现了世界上第一台电动汽车，它是法国工程师Gusave Trouve装配的以铅酸蓄电池为动力的三轮车。此后电动汽车曾盛行一时，1904年，纽约、波士顿和芝加哥等大城市，有1/3的车辆是电动的，其中不仅有轿车，也有载货车。1915年，美国电动汽车的产量达5000辆。但由于电动汽车的蓄电池太重，充电时间长，每一次充电后的行车路程太短，同时汽油机技术发展趋于完善，其轻便、快速、舒适，一次加油能持续行驶400-500公里，燃料费低廉且价格便宜，由于这些原因，使电动车辆逐渐没落了。然而在20世纪末，随着排放法规的日趋严格，电动汽车的优点便显现出来，同时科学的进步也使电动车辆的实用化成为可能。现代电动汽车绝不是百年前阵旧技术的重复，它是汽车、电力拖动、电子、智能控制、化学能源、计算机、新能源、新材料工程技术最新成果的集成产物。 3电动汽车的技术现状 电动汽车与燃油汽车在外形上没有什么区别，它们之间的主要区别见下表一，其余部分基本相同。
