I perswaded somebody in Italy, who laboured very much to speak Italian, that always provided he desired but to be understood, and not to seek to excell others therein, he should onely imploy and use such words as came first to his mouth, whether they were Latine, French, Spanish, or Gascoine, and that adding the Italian terminations unto them, he should never misse to fall upon some idiome of the countrie, either Tuscan, Roman, Venetian, Piemontoise, or Neapolitan; and amongst so many severall formes of speech to take hold of one.

我曾在义大利时建议某个人，既然他非常努力想学义大利文，却仅仅只是需要被了解，又不期望有什麼特出成就的话，他实在只要使用任何他信手捻来的字就好了，管它是拉丁文、法文、西班牙文还是加斯孔方言，只要加上义大利文字尾就成，而且这样绝对正好会搭上某种义大利方言的说法，诸如托斯卡纳、罗马、威尼斯、皮耶德蒙或是拿坡里，而且在各种文法组合里，总会用到一个对的。

In this paper mainly predictive expressions for porous materials are described.The thermal conductivities of rock wool and calcium silicate insulating materials havebeen calculated by these expressions,however,it has been found that there is somedeviation of calculated values from measured data for these insulating materialscontaining structural water.The effect of the structural water on thermal conductivityhas been studied by means of TG-DTA curves of rock wool and calcium silicateinsulating materials,and...

本文介绍了预测多孔材料导热系数的主要计算方程，通过岩棉保温材料和微孔硅酸钙保温材料导热系数的预测，指出这些方法在预测含有结构水的微孔硅酸钙保温材料导热系数时，与实测值会有较大的偏差，进而利用岩棉和微孔硅酸钙保温材料热重和差热曲线，研究了材料结构水对其导热系数的影响，提出了预测含有结构水的多孔材料导热系数的修正方法，其结果与实测值相当吻合。

And destruction usually occurs on angle.(2)Around the keyhole, the stress centralizes, column" edge opt to inflects in local.(3)The change of friction coefficients or bolt pretension forces can"t affect the performance of top-and-seat angel connections so much.(4)The parameters of angel influence joints performance greatly.

破坏一般是由于顶角钢上应力过大，形成塑性铰而导致的；(2)柱翼缘在与顶角钢相连的螺栓孔周围，存在应力集中，容易导致局部屈曲；(3)材料抗滑移系数的改变和螺栓预拉力的大小对于节点受力性能的影响并不明显；(4)角钢参数的改变对节点的各项性能影响显著，增加角钢厚度，节点的强度、刚度和延性都能得到明显的提高；增加角钢长度，节点的强度和刚度也有较大的提高，延性则略有下降；(5)柱轴压比过大时，节点的承载力、刚度以及变形能力明显下降；(6)螺栓中心线到角钢肢背距离增大时，节点的强度和刚度有所下降，但延性略有增加。
