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,All the elevator safety incidents.The coral on the fourth grade students beam elm together use your head,Imagine a"Prevent fall well safety elevator".In just the end of the eighth China youth academy of sciences"Small academician"Research results show the communication activities,She based on this research topic,Was appointed China youth academy of sciences(The central committee of the communist/The national ShaoGongWei create)Top ten small academician,Is also the 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 a the biggest elevator accident harm."Beam elm said together,She thought"Prevent fall well safety elevator"Is the rope suddenly when fracture,Clamp elevator,To avoid personnel falling to the elevator shaft.Yesterday morning,in"Prevent fall well safety elevator"The model of the demonstration,Beam elm paper together the operation principle."First in the elevator car installed in the photoelectric sensor,Then in the side of the solid wall with black and white horizontal stripes,When the photoelectric sensor detection to two black intergalactic space time difference less than normal value,Will quickly tell elevator fall.At this time,Start the base rubber tire braking system,In the tire when friction,Slow down the elevator fall and finally fixed 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。

Chinese academy of sciences, China's remote sensing satellite ground station researchers in the field PanXiZhe pointed out,Prevent fall well safety elevator idea is practical,But must be in the elevator shaft side for solid wall under the premise of to use.At present,Beam elm of together"Prevent fall well safety 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。

Beam elm together ideas began in July last year,In the computer access to the elevator related information,Beam elm together first made a five problems of the questionnaire.You met the elevator safety accident?Cause accidents most what is the main reason……She to the school and residential area fifty questionnaire were issued.Subsequent fall prevention well safety elevator creation experiment,For ten years old beam elm in together,Problem is a lot of,Such as how to install the elevator cable/How to program to make the machine operation, etc..When the beam elm together often want to give up,School science teacher always teach good al,And encourage her to adhere to the experiment.

从女儿上一年级开始 爸爸带她到处看科技活动 From grade one daughter began to dad take her look around science and technology activities

　　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 primary school grade one in the national youth for the first time since the robot contest,Beam elm together outside the city for five times in the large-scale science and technology competition,Created a serpentine rescue robot/Soccer robot/Sweep road inventions such as the robot.Beam elm mentioned together,In addition to the school the teacher's guidance,Dad LiangHong influence to small. LiangHong is nanan distract teenagers technology coaching center staff,From the beam elm together a grade in elementary school began,He took his daughter watching the city major science and technology activities,Beam elm to science and technology together gradually interested.

　　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 accompany the daughter at home often build model,LiangHong back to their established a teaching task,"In the daughter elementary school a grade,Teach her to design and build model;Second grade is programming,Such as make the model according to the established line operation;three/Grade four taught her to model specification different 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 also interested in science and technology creation,LiangHong Suggestions,Parents must first learn to respect,Don't deny or underestimate a child's idea,If unrealistic,Let them to practice has proved;secondly,Science and technology creation of the logical thinking ability have certain requirements,The level of the small children in the practice of the loss,Parents must be good at guiding.(Trainee reporter yuan tie)
