科技小论文范文环境与光污染一、课题背景:随着现代都市的发展,出现了一种新的污染——光污染,它已成为现在都市的环境公害,影响人们的身心健康。而这种光污染是由反光、反热的建筑材料造成的,如一些大厦的玻璃幕墙。在下午约2~4时折射的太阳光正好对着公路,司机们的视线受到干扰,存在安全隐患。在深圳也存在此种问题,特别是繁华地段的高层反光反热的玻璃幕墙,因此,本小组在我市的繁华地段进行调查研究,开展了“光污染”的课题研究。二、课题目的:认识和了解光污染的有关知识。调查城市光污染,并提出有关建议。学会团结合作,学会对知识的探讨与研究。��  三、课题研究过程与方法:查找资料:上网查找,翻阅书报。收集资料。(1)光污染分为人造光与自然光,这些光照对人体有害处。(2)人对光的色彩有何反应。(3)光污染对各种人群的危害。实地调查(1)对行人、司机的采访。 (2)采用拍照,进行实情记录。总结整理(1)整理资料,分析内容。(2)制作网页。四、研究结果和分析:光污染及其危害根据环境科学的解释,光污染是指过量的光辐射,紫外线辐射和红外线辐射对人体健康,人类生活和工作环境造成不良影响的现象。(1)眩光�造成光污染的光辐射中常见的是眩光。眩光是指在视野内有光亮度范围不适宜,在空间或时间上存在着极端的光亮度对比,以致引起不舒服或降低可见度的视觉现象,玻璃幕墙的光污染就是由于其反射太阳光、灯光等光线过强造成眩光。眩光使人的视力下降并迅速疲劳,日常生活中的眩光污染有很多,如夜间迎面而来的汽车前灯的眩光会使受到光刺激的司机和行人控制力降低,很容易发生危险等。 (2)自然光自然光主要来源太阳辐射。太阳光主要有紫外线、红外线、可见光等。而光污染是指过量的光的辐射,紫外光的辐射,能对人体健康、人类生活和工作环境造成不良影响。如:受日光中的紫外线过度的照射,便会引起日光性皮肤炎,会使人身体暴露部位红肿,严重者起水疱,患部有灼热,刺痒或疼痛感;病情严重时,可伴随身体不适、发烧、恶心及心跳加速,长期日晒过量会造成慢性损害,长期照射阳光,紫外线能诱发皮肤癌。但适量的阳光照射是必要的。(3)反射太阳光反射太阳光,这种光污染是城市中最为严重的。例如,我市的建筑,虽然以玻璃幕墙为主,是很美观,但在美丽的背后却潜藏着杀机,它给周围的人带来了很多危险,如:使正常细胞衰亡,出现血压升高,心急燥热等不良症状,还可以使人的视力下降尤其是眩光。(4)人造光人造光就是指我们日常使用的电灯,舞厅用的彩灯等。在舞厅里,我们看到的灯光五光十色,美丽万分,可你对它的危害又认识多少呢?各式各样的彩灯是光污染的来源之一。彩灯虽然能够强烈的刺激感官,同时刺激也能病发细胞,使人的眼睛不适,影响人的中枢神经,令人产生头晕目眩,站立不稳的感觉,长期处于这种灯光下会引起头痛,失明,食欲不振。此外经科学研究表明,彩光能给人产生心理压力,不同的颜色有不同程度的心理压力。 �(5)彩光心理压力指数灯光颜色 白光 黄光 绿光 蓝光 紫光 红光 黑光压力指数 100 113 133 152 155 158 187(6)光污染如何导致近视作为学生的我们受到光污染的危害就更严重了,现代学生的近视眼有不断上升的趋势,其中必不可少原因是光污染。学生所用的台灯,光质分为红外光、紫外光。红外光易被水分吸收,而人的眼球80%左右是水分,长期吸收红外光会使眼组织变异;紫外光有穿透力,杀伤力强,长期受紫外光辐射,眼细胞受到伤害。台灯的光污染会对眼睛造成疲劳,损伤,从而使视力下降。光污染的防治与建议(1)在光污染比较严重的地区,可以多植树,树木可以减少光污染的强度,从而减少光污染对人体的影响和危害。(2)在交通繁忙地区的建筑物应少用或不用反光、反热的建筑材料,最好使用不反光、不反热的建筑材料。(3)住宅区不用反光、反热性强的建筑材料,因为它会直接危害到人们的健康,生活习惯。(4)若使用反光的建筑材料做外墙,应有自动转向反光系统。如:两栋楼隔着一定的距离而对立,若太阳光从对面大楼方向射过来,那么这栋大楼的反光外墙通过自动反光系统调节一定的角度,射向另一栋大楼再经过自动反光系统,把光反射到天空去,这种设想的可行性是可以的,但依现在的科技水平要完成这一系统是不可能的,它需要高新的科技与高能量的消耗,因此这种想法只有在未来实现了。

写作思路:根据为科技主题,以为发展基调来展开描写,紧扣叙述与描写的内容,力求做到不突兀、不生硬,不长篇大论或肆意抒情,有情真意切之感。范文:It can be expected that there will be a breakthrough in life sceience and space science in the 21st century First, scientists will conquer incurable diseases through the transformation of genes可以预见,21世纪生命科学和空间科学将取得突破性进展。首先,科学家将通过基因转化来战胜不治之症。With the same technology they can breed new species of animals and even human life in the laboratory Most important of all, they can decelerate aging and prolong life用同样的技术,他们可以在实验室培育出新的动物物种,甚至人类的生命。最重要的是,它们能延缓衰老,延长寿命。Besides, permanent stations will be set up in the moon or other planets or stars so that scientists can make a thorough study of the moon and other planets or star此外,还将在月球或其他行星或恒星上建立永久观测站,以便科学家对月球和其他行星或恒星进行深入研究。扩展资料英语想写好作文,必须具备扎实的基本功,作文的基本功主要体现在词、句、段三个方面。单词方面,积累单词,扩大词汇量,弄清词的确切用法及相似词的用法区别,以及很多固定短语、习语的用法,要准确地表达想要表达的意思。句子方面,注意一些常用的句式,平时看到比较好用的句式要记下来,多模仿,还要在写文章时注意长短句的结合。段落方面,注意整篇文章的整体布局,要从整体上把握每段的中心思想,避免偏题、走题。提高写作水平不是一朝一夕所能完成的,最重要的是养成好的学习习惯,平时注意多积累,勤动笔、多思考,潜移默化中写作水平便会不断提高。

科技小论文  ——警惕全球变暖  最近这几年,大家觉得天气一下子就变热了,原本凉爽的秋天现在几乎要到10月下旬才开始,8月份最热的天居然达到了40度以上。这是为什么呢?原来,是人类自己惹的祸。  随着人类高科技发展进程越来越快,科学随之产生的副作用逐渐体现出来,全球变暖就是一个例子。天气炎热,在酷暑里泡空调成为了一项新的“业余爱好”,但人们可曾想过,空调会带来什么负面影响呢?答案当然是肯定的,空调排放的气体中含有大量的甲烷,输送到外面,甲烷也是导致全球变暖的气体。同时,空调还会浪费掉许多电,所以要尽量避免用空调,适当即可。  而另一个原因就是:二氧化碳!汽车尾气与工厂废气中含有大量二氧化碳,而二氧化碳最可能导致温室效应(即全球变暖)现在汽车逐渐增多,据有关方面统计,到21世纪,汽车在全世界已有7亿辆,大量的尾气严重影响着我们,咳嗽,喉咙发炎……最重要的是全球变暖。有人统计,美国人均二氧化碳排放量已达到了20吨一年!中国每年的二氧化碳排放量人均排放量也有51吨一年!我们周围的环境在恶劣地变化。  更重要的原因就是:森林锐减,水资源破坏,生态链严重被破坏,大量土地贫瘠,水污染严重,据统计全世界10%的河水被污染,新鲜的淡水供应成了问题,同时由于矿物质被大量使用,燃烧出的CO2气体导致了大气污染,同时臭氧层被严重破环,南北极出现臭氧层洞,加剧了环境的恶化。这样恶性循环的话,最终会导致人们的生活被严重影响。  这样一来的悲剧是什么呢?当然是显而易见了!天气加热,海平面上涨,南北极冰川融化,海滨城市,岛国被淹。这一切,都严重影响了人类的生存,实验证明,以后300年,海平面将上涨半米多,这还是最乐观的数据。再过7年,全球变暖将会无可逆转地持续。更可怕的是,由于北极冰融化,降雨量加强,大量淡水汇入北大西洋,破坏了墨西哥暖流,一旦墨西哥暖流被切断后,欧洲西北部温度将会下降5—8度之多,从而造成的影响,很可能引发新的冰河时期!想必大家一定看过《后天》这部电影,剧中的情景正是几百年后对我们地球的一个真实写照:龙卷风,冰层断裂,温度急剧下降,冰风暴,冻雨,地震,洪水,海啸……这并不是疯狂的幻想,如果人类不停止毁坏环境的话,这将成为现实!全球变暖不仅仅是天气变热,更会牵连出许多负面影响!  为了拯救地球,我们应该尽量做到:不开空调,使用回收环保纸张,舍弃肉类(牛排)食品(牛消化中含有一氧化二氮,如果你转为素食主义者,每年二氧化碳的排放量将减少5吨!)不用塑料袋,乘公交车……生活中的点点滴滴。其实环保并不难,只要你支持环保,就是你给这个星球的最好礼物,不需要太多言辞,只要每个人都行动起来,就会是一股强大的力量!如今,日本,英国,美国等国家纷纷行动起来,我们虽然也采取了行动,但,对于一个有13亿人口的泱泱大国,这一点,还是不够的。  所以,警惕全球变暖,是全人类为了挽救地球的唯一方法,有人也许会说:我们不是可以移居到别的星球上去吗?答案虽是肯定的,但那又能容纳多少人呢?有人说:治理温室效应的资金太大了,对金融来说是天价。但,如果一直拖延,最终的结果,是我们的地球面目全非,别说金融,就连自己的生命也难保啊!所以环境保护不应只停留在口头上,而要真正付之与行动了!

科技小论文范文环境与光污染一、课题背景:随着现代都市的发展,出现了一种新的污染——光污染,它已成为现在都市的环境公害,影响人们的身心健康。而这种光污染是由反光、反热的建筑材料造成的,如一些大厦的玻璃幕墙。在下午约2~4时折射的太阳光正好对着公路,司机们的视线受到干扰,存在安全隐患。在深圳也存在此种问题,特别是繁华地段的高层反光反热的玻璃幕墙,因此,本小组在我市的繁华地段进行调查研究,开展了“光污染”的课题研究。二、课题目的:认识和了解光污染的有关知识。调查城市光污染,并提出有关建议。学会团结合作,学会对知识的探讨与研究。��  三、课题研究过程与方法:查找资料:上网查找,翻阅书报。收集资料。(1)光污染分为人造光与自然光,这些光照对人体有害处。(2)人对光的色彩有何反应。(3)光污染对各种人群的危害。实地调查(1)对行人、司机的采访。 (2)采用拍照,进行实情记录。总结整理(1)整理资料,分析内容。(2)制作网页。四、研究结果和分析:光污染及其危害根据环境科学的解释,光污染是指过量的光辐射,紫外线辐射和红外线辐射对人体健康,人类生活和工作环境造成不良影响的现象。(1)眩光�造成光污染的光辐射中常见的是眩光。眩光是指在视野内有光亮度范围不适宜,在空间或时间上存在着极端的光亮度对比,以致引起不舒服或降低可见度的视觉现象,玻璃幕墙的光污染就是由于其反射太阳光、灯光等光线过强造成眩光。眩光使人的视力下降并迅速疲劳,日常生活中的眩光污染有很多,如夜间迎面而来的汽车前灯的眩光会使受到光刺激的司机和行人控制力降低,很容易发生危险等。 (2)自然光自然光主要来源太阳辐射。太阳光主要有紫外线、红外线、可见光等。而光污染是指过量的光的辐射,紫外光的辐射,能对人体健康、人类生活和工作环境造成不良影响。如:受日光中的紫外线过度的照射,便会引起日光性皮肤炎,会使人身体暴露部位红肿,严重者起水疱,患部有灼热,刺痒或疼痛感;病情严重时,可伴随身体不适、发烧、恶心及心跳加速,长期日晒过量会造成慢性损害,长期照射阳光,紫外线能诱发皮肤癌。但适量的阳光照射是必要的。(3)反射太阳光反射太阳光,这种光污染是城市中最为严重的。例如,我市的建筑,虽然以玻璃幕墙为主,是很美观,但在美丽的背后却潜藏着杀机,它给周围的人带来了很多危险,如:使正常细胞衰亡,出现血压升高,心急燥热等不良症状,还可以使人的视力下降尤其是眩光。(4)人造光人造光就是指我们日常使用的电灯,舞厅用的彩灯等。在舞厅里,我们看到的灯光五光十色,美丽万分,可你对它的危害又认识多少呢?各式各样的彩灯是光污染的来源之一。彩灯虽然能够强烈的刺激感官,同时刺激也能病发细胞,使人的眼睛不适,影响人的中枢神经,令人产生头晕目眩,站立不稳的感觉,长期处于这种灯光下会引起头痛,失明,食欲不振。此外经科学研究表明,彩光能给人产生心理压力,不同的颜色有不同程度的心理压力。 �(5)彩光心理压力指数灯光颜色 白光 黄光 绿光 蓝光 紫光 红光 黑光压力指数 100 113 133 152 155 158 187(6)光污染如何导致近视作为学生的我们受到光污染的危害就更严重了,现代学生的近视眼有不断上升的趋势,其中必不可少原因是光污染。学生所用的台灯,光质分为红外光、紫外光。红外光易被水分吸收,而人的眼球80%左右是水分,长期吸收红外光会使眼组织变异;紫外光有穿透力,杀伤力强,长期受紫外光辐射,眼细胞受到伤害。台灯的光污染会对眼睛造成疲劳,损伤,从而使视力下降。光污染的防治与建议(1)在光污染比较严重的地区,可以多植树,树木可以减少光污染的强度,从而减少光污染对人体的影响和危害。(2)在交通繁忙地区的建筑物应少用或不用反光、反热的建筑材料,最好使用不反光、不反热的建筑材料。(3)住宅区不用反光、反热性强的建筑材料,因为它会直接危害到人们的健康,生活习惯。(4)若使用反光的建筑材料做外墙,应有自动转向反光系统。如:两栋楼隔着一定的距离而对立,若太阳光从对面大楼方向射过来,那么这栋大楼的反光外墙通过自动反光系统调节一定的角度,射向另一栋大楼再经过自动反光系统,把光反射到天空去,这种设想的可行性是可以的,但依现在的科技水平要完成这一系统是不可能的,它需要高新的科技与高能量的消耗,因此这种想法只有在未来实现了。
