一、节能、隔音

的导热系数为0.325w/m.k，大约是粘土瓦的1/3，10mm厚水泥瓦的1/5，0.5mm厚彩钢瓦的1/2000。在不考虑加保温层的情况下，瓦的保温性能仍能达到最佳。通过音位测定实验表明，在遭受暴雨、冰雹、大风等外界影响时，瓦都能很好的吸收噪音。

二、抗冲击耐低温效果好

1公斤重的钢球自1.5米高度自由落在瓦面上不产生裂纹。经过10个冷冻循环，瓦无空鼓、气泡、剥离、裂纹现象。

三、色彩持久

该即使长期暴露于紫外线、湿气、热、寒和冲击下，仍能保持其颜色的稳定性。通过国家化学建筑材料测试中心12000小时的人工老化测试，检测结果△E=2.86。

四、卓越的抗荷载

通过国家化学建筑材料及构件质量监督站检测，在支撑间隔750mm情况下，加重150kg，产品没有被破坏。

五、卓越的自防水性能

所选用的高耐候性树脂本身致密且不吸水，不存在微孔渗水的问题。的单张面积大，屋面接缝少，搭接处结合严密，可以省去防水层。

六、质量轻

每平方米重6.1kg是一种轻质材料。无需加装过多钢结构，对墙体、地基承重要求小。

七、自清洁

该产品本身不宜吸附灰尘，一经雨水冲刷便洁净如新，不会出现积垢后被冲刷的斑斑驳驳的现象。

八、优异的耐腐蚀性能

该产品可以长期抵御酸、碱、盐等各种化学物质腐蚀，不会被雨雪侵蚀导致性能下降。

九、耐火性强

该产品主体树脂属难燃产品，经国家防火权威部门检测防火性能达到B1级。

十、体积稳定

的膨胀系数为4.93×10-5(1/℃)，并在几何形状设计上具有双向拉伸性能，即使温度变化很大，瓦的伸缩也能被自身消化，确保瓦的几何尺寸稳定。

十一、绝缘

该产品的另一个技术特性是不导电，遇到意外放电也会完好无损。

十二、安装简单

该产品只需用螺钉固定在钢檀上，再辅以主脊，斜脊等配件，便可经久耐用，使用寿命长达35年以上。

现象：男人和女人，当他们从所有错误的感觉和厌恶中解放出来，发现彼此不是对立的而是兄弟姐妹和邻居，是一个完整的人类，他们将简单地、认真地，耐心地共同忍受那置于他们身上的沉重的性。

对许多人来说，什么事都可能发生。孤独的人现在已能开始营造，用自己的手，而且犯极少的错误。因此，亲爱的先生，热爱您的孤独并且试着去歌颂那创造了您的痛苦。为了那些曾经与您如此亲密的东西的远离，您写作，这表明您周围的空间已经开始长大了。如果曾经与您亲密过的东西远离了您，那么您广阔的空间就已延伸到了星际，它太大了。为您自己的成长而感到高兴吧。在这成长过程中别人是无法和您一起分享的，但您要温柔地对待落后于您的人；在他们面前要自信和镇定，不要让他们因您的怀疑而感到苦恼，不要让您的信念和快乐吓坏他们，他们无法理解。找一些您能够和他们分享的简单而真实的感觉，那些不随着您的变化一遍一遍地转化的感觉；当您看着他们，要爱那不是以您自己的形式而存在的生活，对那些逐渐变老的要保持宽容，他们害怕您所信赖的孤独。避免为戏剧提供材料，它们总是在父母和孩子之间制造紧张气氛，它耗干了孩子们的力量，浪费了长辈的爱，但是，即使他们不能达成理解，这力量和爱依旧在起着作用，在温暖着人们。不要征询他们的意见，不要期待任何理解；但是相信有一种爱会象遗传一样聚集起来，相信这种爱的力量和祝福是如此强烈以至于您可以携带它旅行到天涯海角。

您要有一份职业了，这很好，您将独立起来并成为完整的自己，从各个方面来说。耐心点等待，您将会知道那职业是否在多方面压抑您的生活。我自己认为这是个艰难但非常兴奋的过程，因为它负载着太多的惯例，个人拥有的自由发挥的空间实在是微乎其微。但是您的孤独将支持您，将成为您的家，甚至在那不甚熟悉的环境里，在那儿您将发现自己的道路。我所有良好的祝愿都时刻伴随着您，还有我的信念。

把握和支撑着。刚读这书的时候，您就能感到巨大的喜悦，书中无数令您惊异的地方使您感觉置身于一个新的梦里。但是我告诉您真正奇妙的事吧：即使以后您再翻开这些书，一遍又一遍地，您仍会带着和初次读它时一样的惊奇，它不会丧失那神奇的力量，也不会散失一点让人无法抵抗的魅力。

您会越来越快乐，越来越感激，在意念里会莫名其妙地变得更好、更简单，而生活的信念会更深刻，生活的方式会更快乐和更亲密。

之后，您将不得不读这本描写玛利亚.阁鲁彼的命运和期望的奇书，还有杰克布森的信和日记及未完成的作品，当然最后是他的诗（即使译文一般），那诗读后余音袅袅。（为此，我建议您在手头不紧张的时候去买来，一套很棒的杰克布森作品全集包括上述所有的内容，共三本，译得很好，由利浦兹的尤根elated to us, have through our daily defensiveness been so entirely pushed out of life that the senses with which we might have been able to grasp them have atrophied. To say nothing of God. But the fear of the inexplicable has not only impoverished the reality of the individual; it has also narrowed the relationship between one human being and another, which has as it were been lifted out of the riverbed of infinite possibilities and set down in a fallow place on the bank, where nothing happens. For it is not only indolence that causes human relationships to be repeated from case to case with such unspeakable monotony and boredom; it is timidity before any new, inconceivable experience, which we dont think we can deal with. But only someone who is ready for everything, who doesnt exclude any experience, even the most incomprehensible, will live the relationship with another person as something alive and will himself sound the depths of his own being. For if we imagine this being of the individual as a larger or smaller room, it is obvious that most

e, with beauty and courage. Perhaps everything that frightens us is, in its deepest essence, something helpless that wants our love.

So you mustnt be frightened, dear Mr. Kappus, if a sadness rises in front of you, larger than any you have ever seen; if an anxiety, like light and cloud-shadows, moves over your hands and over everything you do. You must realize that something is happening to you, that life has not forgotten you, that it holds you in its hand and will not let you fall. Why do you want to shut out of your life any uneasiness, any misery, any depression, since after all you dont know what work these conditions are doing inside you? Why do you want to persecute yourself with the question of where all this is coming from and where it is going? Since you know, after all, that you are in the midst of transitions and you wished for nothing so much as to change. If there is anything unhealthy in your reactions, just bear in mind that sickness is the means by which an organism frees itself from what is alien; so one must simply help it to be sick, to have its whole sickness and to break out with it, since that is the way it gets better. In you, dear Mr. Kappus, so much is happening now; you must be patient like someone who is sick, and confident like some one who is recovering; for perhaps you are both. And more: you are also the doctor, who has to watch over himself. But in every sickness there are many days when the doctor can do nothing but wait. And that is what you, insofar as you are your own doctor, must now do, more than anything else.

Dont observe yourself too closely. Dont be too quick to draw conclusions from what happens to you; simply let it happen. Otherwise it will be too easy for you to look with blame (that is: morally) at your past, which naturally has a share in everything that now meets you. But whatever er
