百叶窗隔断是很多家庭都会选择的隔断种类,既能够保证隔断的效果,而且能够保持光线的通透性。越来越多的家庭想选择百叶窗,但又对百叶窗的了解很少,例如百叶窗有哪些特点呢?百叶窗有隔音效果吗?下面我就为大家来解答百叶窗有哪些特点及百叶窗有隔音效果吗。
百叶窗隔断是很多家庭都会选择的隔断种类,既能够保证隔断的效果,而且能够保持光线的通透性。越来越多的家庭想选择百叶窗,但又对百叶窗的了解很少,例如百叶窗有哪些特点呢?百叶窗有隔音效果吗?下面我就为大家来解答百叶窗有哪些特点及百叶窗有隔音效果吗。
百叶窗有哪些特点:
1、铝合金美观节能,简洁利落?百叶窗可完全收起,窗外景色一览无余,窗户简约大方. 窗帘 则占用了窗户的部分空间,使得 房屋 的视觉窗户的宽度受到影响,显得繁琐。
2、保护隐私以叶片的凹凸方向来阻挡外界视线,采光的同时,阻挡了由上至下的外界视线夜间,叶片的凸面向室内的话,影子不会映显到室外,干净放心,清洁方便。平时只需以抹布擦拭即可,清洗时请用中性洗剂。不必担心退色,变色.防水型百叶窗还可以完全水洗。
3、冬暖夏凉采用了隔热性好的材料,有效保持室内温度,达到了节省能源的目的。简单自由角度调整,控制射入光线,以调整叶片角度来控制射入光线,可以任意调节叶片至适合的位置。
4、阻挡紫外线有效阻挡紫外线的射入,保护家具不受紫外线的影响而退色。百叶窗与窗帘相比,百叶窗那可以灵活调节的叶片具有窗帘所欠缺的功能。在遮阳方面,百叶窗除了可以抵挡紫外线辐射之外,还能调节室内光线;在通风方面,百叶窗固定式的安装以及厚实的质地,可以舒心地享受习习凉风而没有其它顾虑;窗帘的飘摆会室内生活时隐时现,百叶窗层层叠覆式的设计则保证了家居的私密性;此外,百叶窗完全封闭时就如多了一扇窗,能起到隔音隔热的作用。
隔音百叶窗有隔音效果吗:
1、百叶式消声器一般消声量为5～15dB(A),消声特性呈中高频性,百叶式消声器的消声性能主要决定于单片百叶的形式、百叶间距、安装角度及有效消声 长度 等因素。通风消声百叶结构,可消除噪声的窗式结构,根据使用环境需求采用不锈钢、铝合金、镀锌钢板等材料制作,加之特殊加工工艺,在任何气候条件下使用,且气流阻力小,消声量大,外形美观。
2、低频时,安装百叶窗以及百叶窗表面吸声处理的效果不明显。 频率 升高,百叶窗表面吸声处理后,隔声效果明显体现,且各个频率上安装带吸声的百叶窗的房间,内部声压场数值较低。总之,吸声后,百叶窗隔声效果明显提升,频率越高效果越明显。
通过上面我给大家介绍的百叶窗有哪些特点,隔音百叶窗隔音效果好吗。相信大家对百叶窗有了一定的了解,接下来如何选择,是不是要安装百叶窗,大家可以根据自己的喜好来决定。
用LABEL来做移动就是存在闪动的问题，你可以试试加个Frame1试试看，或者用picturebox看看！
实现百叶窗等特效如果不会API可以参考遮盖层的概念！

我认为问题出在这里：
a = GetPixel(Picture1.hdc, X, Y)
b = SetPixel(Me.hdc, X, Y, a)
当你用一次循环，将这些点重设以后，再次来设置，就不会有什么变化了，我感觉应该加上一个恢复状态的语句。改变后，再恢复，然后再点才会有效果。
