过去的一年，各地电梯安全事故频发。南岸珊瑚小学四年级学生梁榆姗开动脑筋，设想了一部“防坠井安全电梯”。在刚刚结束的第8届中国少年科学院“小院士”课题研究成果全国展示交流活动上，她以此为研究课题，被聘为中国少年科学院(共青团中央、全国少工委创建)十佳小院士，也是我市唯一获得该称号的参赛学生。

The past year,Around the elevator safety incidents.South coral primary school grade four students liang yu Susan 'brains,Imagine the a"A fall prevention safety the elevator".In just finished the 8 th China youth academy of sciences"Small academician"Research results show the exchange activities,She based on this research topic,Was appointed China youth academy of sciences(The communist youth league central committee/The ShaoGongWei created)Top ten small academician,Is also the city only to win the title of each student.

　　“缆绳断裂是引发电梯事故的最大危害。”梁榆姗说，她设想的“防坠井安全电梯”就是在缆绳突然断裂时，固定住电梯，从而避免人员坠落至电梯井。昨天上午，在进行“防坠井安全电梯”模型的现场演示时，梁榆姗阐述了运作原理。“首先要在电梯的车厢内安装光电传感器，然后在电梯的一面实体墙贴上黑白相间的横条纹，当光电传感器检测到两条黑条纹间的时间差小于常规值时，就会迅速判断出电梯坠落。此时，启动电梯底座的橡胶轮胎刹车系统，在轮胎相互摩擦时，减缓电梯坠落并最终固定轿厢。”

"Cable fault is the largest of the elevator accident harm."Liang yu Susan said,She thought"A fall prevention safety the elevator"Is the cable suddenly at fracture,Fix the elevator,So as to avoid falling to the elevator shaft.Yesterday morning,In the"A fall prevention safety the elevator"When the presentation of the model,Liang yu Susan expounds the operating principle."First in the elevator of the photoelectric sensor installed in the car,Then in the lift one side of the solid wall with black and white alternate with horizontal stripes,When the photoelectric sensor detect the time difference between the two black stripes less than normal value,Fall quickly figure out the elevator.At this time,Start the elevator base rubber tire braking system,When the friction between the tire,Slow down the elevator down and finally fixed the car."

　　中国科学院中国遥感卫星地面站研究员潘习哲在比赛现场指出，防坠井安全电梯的设想具有实用性，但须在电梯井一面为实体墙的前提下才能使用。目前，梁榆姗的“防坠井安全电梯”的创意发明正准备申请国家专利。

Researcher at the Chinese academy of sciences, China remote sensing satellite ground stations PanXiZhe pointed out at the scene of the game,A fall prevention safety elevator the tentative plan is practical,But must be in the elevator well under the premise of wall of one side for the entity to use.At present,,The beam elm together"A fall prevention safety the elevator"The originality of the invention is going to apply for the national patent.

　　梁榆姗的创意始于去年7月，在电脑上查阅了电梯相关资料后，梁榆姗首先制作了一份有5个问题的调查问卷。你遇到过电梯安全事故吗？造成事故最主要的原因是什么……她向学校和所居住小区共发出50份调查问卷。随后进行防坠井安全电梯的创作实验时，对于10岁的梁榆姗而言，难题真不少，比如电梯缆绳如何安装、如何编程才能使机器运作等。当梁榆姗每每想放弃时，学校科学老师杨建军都始终悉心指教，并鼓励她坚持实验。

The originality of the beam elm Susan began in July last year,After the elevator related literatures on the computer,Liang yu together first made a questionnaire with five problems.You met the elevator safety accident?What is the main reason caused by accident……Her to the school and the residential area of 50 questionnaires were issued.Followed by the creation of the elevator safety fall prevention experiment,For 10 years of liang yu together,Problem is a lot of,Such as how to install the elevator cable/How to program to machine operation, etc..When liang yu Susan often want to give up,School science teacher al are always take counsel,And encourage her to experiment.

从女儿上一年级开始 爸爸带她到处看科技活动 Starting from grade one daughter father take her around the activities of science and technology

　　自小学一年级第一次参加全国青少年机器人大赛以来，梁榆姗在市外参加了不下5次大型科技比赛，创作了蛇形救援机器人、足球机器人、扫道路机器人等发明。梁榆姗提到，除了学校老师的辅导，爸爸梁洪对自己影响也不小。 梁洪是南岸区青少年科技辅导站的工作人员，从梁榆姗上小学一年级开始，他就带女儿现场观摩市内各大科技活动，梁榆姗对科技渐生兴趣。

Since a grade for the first time to participate in the national youth robot contest,Liang yu together outside in the city for more than five large-scale science and technology,Created a snake rescue robot/Soccer robot/Sweep road inventions such as the robot.Liang yu Susan mentioned,In addition to the school the teacher's guidance,Dad LiangHong for myself and influence. LiangHong is nanan distract youth science and technology instruction center staff,Start from liang yu together on a grade,He will take my daughter live watching the city major science and technology activities,Liang yu Susan to science and technology are of interest.

　　除了在家里常陪女儿搭建模型，梁洪还给自己制定了一项教学任务，“在女儿小学一年级时，教她设计和搭建模型；二年级就是编程序，比如让模型按照既定线路运行；三、四年级就教她给模型设定不同的任务。”

In addition to build model often accompany daughter at home,LiangHong back to make a teaching task,"In primary school a grade daughter,Teach her how to design and build models;Second grade is programmed,Such as model according to the given line;three/Fourth grade taught her to model different set of tasks."

　　如果你家的孩子也对科技创作感兴趣，梁洪建议，家长首先需学会尊重，不要一口否定或低估孩子的想法，如果不切实际，让他们自己去实践证明；其次，科技创作对逻辑思维能力有一定要求，当年级较小的孩子在实践中出现迷茫时，家长要善于引导。(见习记者 苑铁力)

If your child is interested in science and technology creation,LiangHong Suggestions,Parents must first learn to respect,Don't be a negative or underestimate the idea of the child,If unrealistic,Let their own to practice;The second,Creation of science and technology requires some logical thinking ability,That level of smaller child confusion occurs in practice,Parents should be good at.(Trainee reporter yuan tie)
