【文章內(nèi)容簡介】 ic gravity熔點(diǎn)the melting point重力加速度the acceleration of gravity 磁導(dǎo)率magnetic permeability熱導(dǎo)率thermal conductivity 1. 化學(xué)性質(zhì)是用來描述一種物質(zhì)是怎樣變成另外一種完全不同的物質(zhì)的性質(zhì)。Physical properties are those that can be observed without changing the identity of the substance. 2. 相變是一種物理性質(zhì)，并且物質(zhì)存在四種相：固相、液相、氣相和等離子體。Phase is a physical property of matter and matter can exist in four phases : solid , liquid , gas and plasma . 3. 當(dāng)溫度低于熔點(diǎn)時(shí)，聚合物的晶體結(jié)構(gòu)破壞，但其分子任然連接在分子鏈上，從而形成一種柔軟和柔順性材料。Instead , at some temperature below the melting point , they start to lose their crystalline structure but the molecules remain linked in chains , which results in a soft and pliable material. 4. 在工程應(yīng)用中，滲透率通常用相對(duì)值而不是絕對(duì)值表示。In engineering applications , permeability is often expressed in relative , rather than in absolute , terms .Unit5： 實(shí)驗(yàn)樣品 test specimen靜負(fù)荷 static loading 作用力 applied force垂直軸 normal axis工程應(yīng)變 engineering strain 臨界應(yīng)力 critical stress屈服強(qiáng)度 yield strength應(yīng)力面積 stress area應(yīng)力應(yīng)變曲線 stressstrain curve 1. 通常，溫度低于室溫時(shí)，金屬合金的強(qiáng)度性質(zhì)降低，而延展性、破碎韌度和拉伸性能增強(qiáng)。Temperature above room temperature usually cause a decrease in the strength properties of metallic alloys. 2. 從材料的角度來說，盈利是一種在材料內(nèi)部所分布的力，他可以平衡所施加的負(fù)荷并與其發(fā)
