注意自身防护，加强个人健康监测：勤洗手，勤消毒，多通风，尽量避免去往人流密集的地方。如出现发热、咳嗽、呼吸困难等症状，请及时就诊。
密切关注美国疾控中心发布的官方信息，不信谣，不造谣，不传谣，摒弃恐慌情绪。
根据个人实际情况制定出行计划，入境时须遵守各国有关疫情防控规定。若启程前已出现疑似症状，请勿仓促出行，避免增加疫情扩散风险。
留意学校关于疫情发展情况的官方信息，关注美国大学预防疫情的相关举措，随时准备调整自身学习计划。

留学签证疫情影响，求真告诉你如何应对！

Posted by Serena Xie on March 24, 2020 at 4:38am

留学签证疫情影响最严重时，美国如何应对？

不少打算赴美留学的同学最近都在考虑这么一个问题，新冠肺炎病毒肆虐之下，还能顺利拿到签证按时赴美留学吗？申请签证疫情影响大吗？我们按照此次新冠肺炎疫情演变的时间轴一步一步进行梳理，力求给予正在保持观望的留学生家庭一个最清晰、最正确的应对策略。

早在2020年1月份，也是新冠肺炎疫情在中国最严重的时刻，美国大使馆宣布自2020年2月3日起，美国驻北京大使馆和美国驻成都，广州，上海和沈阳总领事馆纷纷暂停了普通签证业务包括免面谈申请的办理。同时，美国驻华使领馆也一样，仅维持有限的人员，美国方面也取消了大部分的来华航班。这导致需要赴美留学及工作的人员无法如期归美，事实上1月末已经不属于圣诞假期，多数学校、企业也早在1月中旬就需要学生、员工到岗，可以说受到影响的群体并不多。

而随着国内疫情得到控制，美国大使馆于2月底宣布重新恢复中国公民的赴美签证申请，同时各大航空公司也开始恢复之前关停的部分航班。从网站公布的受理时间上来看，目前最早的签证预约时间是3月12日。不同地区的预约时间有所区别，大家可以在官网上查看。

美国驻华各领事馆预约开放时间：

· 广州领区

可预约最早时间：2020年3月12日

· 沈阳领区

可预约最早时间：2020年3月12日

· 成都领区

可预约最早时间：2020年5月4日

· 上海领区

可预约最早时间：2020年5月19日

· 北京领区

可预约最早时间：2020年5月20日

需要注意的是，可预约时间会根据预约人数而变更，同时也不排除领事馆随时修改预约时间的可能，所以请需要签证的同学们尽早预约。

疫情对于留学的影响，虽然现在很难有定论，但是有一些趋势和分析可以帮助大家进行下一步的规划与准备。

美国高校是否会因此不录取中国学生？

其实大家无需慌乱，即使在之前的中美贸易战过程中，美国总统特朗普也明确表示，美国永远欢迎来自中国的留学生。目前正值美国春季学期开学时间，对于大多数学生来说影响不大，而秋季开学则在每年的8～9月期间，相信届时签证疫情影响已经得到控制，不会影响学生正常入学。美国各大高校也在首页发出公告，会针对受到疫情影响的留学申请给予一定的宽限期，希望广大学生放心申请。

全球抗击疫情的同时，签证政策又将如何变化？

随着境外确诊病例逐日增加，加州大学洛杉矶分校、华盛顿大学、康奈尔大学等美国高校宣布停课。能不能申请留学签证这个问题似乎变成了该不该申请留学签证，毕竟国内各地纷纷传来疫情零增长的好消息的同时，国外疫情好像加重了。求真教育希望提醒大家，随着各国开始重视新冠肺炎病毒以后，恢复正常上学、签证只是时间问题，需要准备的材料、考试一样都不可松懈。每年的6、7月份是留学生集中办理签证的时候，就现在的信息来看，预计今年暑假学生签证不会受到很大影响，但具体情况还是要看那时国外签证疫情影响是否能得到有效控制。

求真寄语

相信六月份左右全世界的疫情都能得到有效的控制，担心签证、考试准备不够充分的同学可以提前联系求真教育，我们拥有丰富的签证办理和留学申请经验，针对此次疫情我们也精心准备了许多应急方案，力求帮助每一位留学生顺利出国留学！

致敬最美逆行者，求真教育在行动

这个冬天格外寒冷，街道上也前所未见的冷清。新冠病毒疫情扩散以来，我们每个人关注的焦点都是与之相关的新闻。在这样压抑的氛围中，卫健委在2月18日发布了一个好消息：全国除湖北以外的新增病例达成“14连降”，冰消雪融，疫情拐点或在不远的将来。

我们每个人的生活都或多或少因这场疫情而发生了改变。商铺关闭、人们在家隔离、学生停课、医护人员化身“白衣战士”、各方倾力支援……

对中国留学生来说，2月无疑是纠结的一个月，受疫情影响，美、澳等国颁布禁止入境政策；2/3月中国考区的雅思、托福、GRE、SAT等重大考试也相继宣布取消；但这同时也意味着申请者有更充足的备考时间。同时也有一些暖心的消息：美国不少大学为中国学生开辟了特别通道、提交成绩截止时间有一定程度的推迟、duolingo在线测试可以暂时当作托福的备选项等；因此大家一定要关注自己学校发布的政策、及时联系校方。

“其实大家无需慌乱，即使在之前的中美贸易战过程中，美国总统特朗普也明确表示，美国永远欢迎来自中国的留学生。目前正值美国春季学期开学时间，对于大多数学生来说影响不大，而秋季开学则在每年的8～9月期间，相信届时疫情已经得到控制，不会影响学生正常入学。”

可以说，留学生们焦急地企盼着这场战“疫”的胜利，确诊人数增速减缓、治愈病例越来越多……关于战“疫”一个又一个好消息不断地鼓舞着我们，令人信心满满。我们深知，这些“战果”都是前线和各地医护人员争分夺秒换来的生命之路。
根据中国疾控中心2月17日报告显示，共有3019名医务人员感染了新型冠状病毒（包括确诊病例、疑似病例、临床诊断病例及无症状感染者，其中确诊病例1716名），该数据中可能存在非职业暴露造成的感染。

这不是冷冰冰的数字，而是鲜活的人；也许昨天这些人还在一线抢救病人，今天就不幸被感染，自己隔离、与病魔抗争。在这场规模空前的对抗病毒的战斗中，全国成千上万名“白衣战士”们冒着生命危险扶大厦于将倾，拯救人民于危难。他们有的献出了宝贵的生命，有的失去了健康，有的无法与亲人团聚，就是这样他们被誉为“最美逆行者”，谱写着一首首生命的赞歌。图源：新华社丘吉尔曾经这样评价英国皇家空军：“在人类征战的历史中，从来没有这么多人对这么少人，亏欠这么深的恩情。”这句话现在看来，再适合中国的白衣战士不过了。他们为了14亿国人的健康，用生命在战斗；说是用生命扛起了14亿人也不为过。图源：钧正平工作室近日医护人员的睡姿流传到了网上，令人心疼又肃然起敬，他们最大限度压缩了自己的休息时间，只为能从疫魔手中抢回更多的生命。

这些照片一次次地提醒着我们，白衣天使，不过是普通人披上了战袍。他们学着前辈的样子，和死神抢时间……此次此刻，纵有千言万语，也无法表达心中的敬意，也只有一声“谢谢”，谢谢您们的辛苦付出！

求真教育对无私奉献的医护人员致以最高的敬意与谢意，除了关注疫情和及时联络捐赠，还希望能用自己的方式来表示感谢，面向所有受到疫情影响的学生，提供更便利、更优质的留学方案，更向全国奋战在抗疫第一线的医护人员们致以最高的敬意！

留学生小伙伴无需焦虑，美国大学依旧欢迎中国留学生并且已经作出相关调整与利好措施。相关的考试、签证虽然在暂停中，但待疫情结束后将全面恢复正常。我们相信没有一个冬天不可逾越，在医护人员和各方的共同努力之下，春暖花开的那一天会早日来到。感恩白衣战士，铭记每一份无私的付出。

美国留学疫情期间，各大学校已进入停课状态！

求真寄语

美国留学疫情日渐险峻，求真教育将同步为学生留意各个学校最近的授课情况。根据病毒的传播性，我们应一起为抗“疫”行动努力。同时，求真教育就已联络武汉大学驻大纽约地区校友会并认捐1000枚N95口罩支援武汉。我们热切地在疫情之战中大家可以加强自我防护措施，保护好自己。求真教育与你一起，打赢这张战“疫”。最后，求真团队向所有在一线忙碌和奋斗的医护人员致敬！

住宿

UCLA的住宿楼基本都位于山上，宿舍共分为五个宿舍群，每一个宿舍群的风格都不同，学生可根据自己的喜好来进行选择。UCLA宿舍群共有经典、豪华、广场、和套间四中类型，经典宿舍的费用较低，但空间也比较狭小，代表楼有Hedrick Hall、Sproul Hall等；豪华宿舍比较适合双人、与三人，生活区域较大，代表楼有Sproul Landing，Sproul Cove等；而广场和套间适合单人、双人、三人入住，次宿舍类型与酒店更为类似，设施更加齐全与豪华，代表楼有De Neve Plaza A-F，Saxon Suites等。每一个宿舍群里都设有食堂、会议室、公共学习室、洗衣房，并且提供银行和快递服务。在每一层宿舍楼里，UCLA都提供了公共洗衣房，公共洗衣房里都有洗衣机与烘干机，为学生提供了更加方便的生活环境。公共学习室则为小组学习的学生们提供了良好的学习环境，大学中不少的小组作业都需要学生一起合作，此时，公共学习室便成为了学生们最好的学习场地。在紧张的课程学习之余，有些宿舍楼也为学子们提供了娱乐房，在繁忙的学业下，为了缓解压力，学生们可以在娱乐房中放松自己，忘记烦恼。

食堂

UCLA以学术著名的同时，食堂也备受学生们的欢迎。在繁重的留学课业之下，吃也成为了学生们不可忽视的一部分。UCLA共有四个较大的食堂，分别为De Neve，Covel，Feast，Hedrick Dining Hall和Bruin Café。最大的食堂De Neve可以容纳700多人，在De Neve里可以尝到各地的美食，汉堡、pizza、各种牛肉羊肉都是学生们的选择，当然冰激凌、奶昔也应有尽有。学习到深夜们的同学也不必担心没有食堂可以去，De Neve将会是学生们吃上宵夜的最佳地方。Covel食堂则是地中海美食的地盘，里面有着各式各样的欧式美食，但在享受美食的同时也不要忘记控制食物油脂摄入，Covel食堂里热乎乎的薯条和奶酪蛋糕都颇受学生们的欢迎。Feast是各大UCLA学生们心中的“神仙”食堂，这里每天都有不重样的亚洲美食，日料、韩餐、中餐包学生们吃得开心，当今的人气美食例如宫爆鸡丁、寿司，章鱼小丸子、刺身等都会经常出现在Feast食堂中。由于人气火爆的原因，去Feast往往会找不到位置，但为了美食耐心等待一下也是值得的！Bruin Plate作为UCLA里最健康的食堂，食堂使用环保餐具，使用有机食物，为学生提供了最健康的餐饮。有时学生在课间来不及去食堂里用餐，不用担心，Bruin Plate的沙拉，水果杯，酸奶，三明治都是学生们的选择。

在繁忙的课业学习中，优越的住宿群与良好的食堂都让学生们更加坚定地选择UCLA，在学生们忙于学业的同时，也不忘了满足自己的胃；在赶完一个又一个作业的同时，也不忘给学生提供了和家一样温暖的地方休息。UCLA作为顶尖名校，在各个方面都极为突出，因此它越来越是学生们心中最向往的学校之一。

【案例】生活变故造成GPA下跌，求真助你回到正轨

Posted by Serena Xie on March 24, 2020 at 4:20am

GPA下跌

GPA下跌有多严重？作为申请美国本科的第一审核标准，GPA的数值决定了大学对一名学生的直接评价，GPA高的学生表示拥有良好的学习处理能力，GPA低的学生则代表其差劲的学业生活状况。大多美国名校都会有一个潜在的GPA标准，GPA未达标的学生，不论材料准备得多充足、文书润色得多精致，都会在第一关被刷下。由此可见，维持一个漂亮的GPA成绩是留美学生的学业生涯中最重要的任务。

但生活中总会有些变故，许多学生会因为一些家庭、感情或身体状况出问题而影响GPA下跌，这时该怎么做才好呢？

Ｃ同学案例

Ｃ同学初来美国，对美国文化和大学课业不是很熟悉，前几学期屡屡考试失误，成绩一落千丈，接连挂科，入学大半年都在重修语言训练课程，导致修课时间无限拉长。Ｃ同学联系求真教育转学团队时，成绩已荡在低谷，好不容易在求真团队的倾力支援下有了起色，却又因感情生活不顺，造成心理问题就医，无法专注课业，成绩再度下跌。

求真助力

C同学学业路途坎坷，求真教育团队倾尽全力为替他铺平学路，诚挚希望能让C同学顺利升上理想院校。

C同学在找到求真转学团队时，成绩已落在GPA2.0以下，求真顾问老师当即为他安排了一系列的课外辅导，请到求真专业的学术辅导老师进行一对一教学，并且多方关心C同学的在校生活，进行电话访查，倾力帮C同学适应美国大学生活。

在进入求真服务的两个学期，C同学的成绩飞速往上窜升，两学期皆获得了GPA3.0以上的佳绩，C同学也在求真团队的扶持下逐渐适应了美国课业，眼看一切都在好转，却又因突发的感情事故和心理问题而造成GPA下跌。

事发突然，求真顾问老师也没气馁，多方鼓励学生，替C同学介绍专业心理医师，同时为他向学校申请Vacation quarter，可修习低于学校最低要求的学分数，暂时减轻同学的课业压力。

经过一学期的调适与治疗，C同学逐渐走出心疾，积极投入课业，在求真顾问老师的帮助下报名托福考试，勤奋与求真辅导老师练习英语和进行模拟考，争取考出好成绩。

近期，C同学在托福考试上取得高于自己预期的高分，重拾对学习的信心，GPA也再度回升，迅速往3.0迈进。

Composition of Different Achromatic Doublet Lenses

Posted by hypoptics on March 23, 2020 at 4:34am

Composition of Different Achromatic Doublet Lenses

Achromatic doublet lensis a kind of common lens. It consists of several groups of positive and negative cemented lenses with different radius of curved surface. It can only correct the axial chromatic aberration of red and blue light in spectral line. At the same time, the spherical aberration on the axis and the coma aberration on the paraxial point are corrected. This kind of lens can not eliminate the second-order spectrum, only the spherical aberration and chromatic aberration in the yellow and green wave regions are corrected. The spherical aberration and chromatic aberration of the remaining chromatic aberration and other wave areas can not be eliminated, and the image field bending is still very large, that is to say, only the clear image in the middle of the field of view can be obtained. It is advisable to use yellow-green light as illumination source or insert yellow-green filter in the optical path. This kind of lens is simple, economical and practical. It is often used in conjunction with correction eyepiece and is widely used in medium and low power microscopes. In black-and-white photography, green filters can be used to reduce the residual axial chromatic aberration and obtain good contrast photographs.
Complex achromatic doublet lens is composed of several groups of advanced lenses made of special optical glass and fluorite. The axial chromatic aberration is corrected by red, blue and yellow light, and the secondary spectrum is eliminated. Therefore, the image quality is good, but it is difficult to process and calibrate many lenses. The correction of chromatic aberration is in all wavebands of visible light. If blue or yellow filters are added, the effect will be better. It is the best objective in the microscope. It has good correction for spherical aberration and chromatic aberration. It is suitable for high magnification. However, it still needs to be used with compensating eyepiece to eliminate residual chromatic aberration.
Planar achromatic doublet lens is a complex optical structure composed of multiple lenses, which can correcting astigmatism and image field bending well, and make the whole field of view clear. It is suitable for microphotography. The correction of spherical aberration and chromatic aberration of the objective is still limited to the yellow-green wave region, and there is still residual chromatic aberration.
Planar achromatic doublet lens has the same degree of aberration correction as complex achromatic objective lens except for further image field bending correction, which makes the image clear and flat. But the structure is complex and difficult to manufacture.

LED Demister Mirror

Posted by hangzhoumirror on March 22, 2020 at 10:30pm

Led Demister Mirror Principle & Function

With the improvement of living standard, more and more people have much more request to a bathroom mirror. One of the biggest requests to bathroom mirror is anti-fog function. Most people like a hot shower on a cold, wet day, but that usually result a steamy mirror.
