Unit 1 General Chemistry Lesson 1Inorganic Chemistry 无机化学是一门涉及化学性质和无机化合物反应的化学学科分支。
无机化学包括了所有除了那些基于链或环的碳原子的被称为有机化合物,并在有机化合物的独立标题下研究有机化学的化合物。
两学科之间的区别并不是绝对的,两者之间有许多重叠,最重要的是在有机金属化学的分支学科上。
1.主要概念无机化合物主要是盐,它是通过阴、阳离子通过离子键键合形成。
例如:阳离子钠Na+和镁Mg2+分别与阴离子氧O2—-和氯Cl-形成化合物。
盐都是电中性的,如离子化合物氧化钠Na2O或氯化镁MgCl2。
这些离子的电性可以由他们的氧化态和易于形成可以从他们母体元素中的电离电位和电子亲和力推断出来的来描述。
一类重要的无机化合物是氧化物,碳酸盐、硫酸盐和卤化物。
许多无机化合物都具有很高的熔点。
固态无机盐是典型的不良导体。
另一个重要性质是他们在水中的溶解度和容易结晶。
有些盐(例如NaCl)极易溶于水,另一些(例如二氧化硅)是不易溶于水的。
最简单的无机反应是复分解反应,即在两种盐的混合物中,离子相互交换但不发生电荷及化合价的改变。
在氧化还原反应中,氧化剂的化合价降低,还原剂的化合价升高,最终的结果是发生了。
交换电子也可以间接发生,例如电池——电化学中一个很重要的概念。
在酸碱化学中,反应物包含氢原子的反应可以通过交换质子发生。
更广泛的定义就是:在任何化学种类里能结合电子对的被称为路易斯酸,相反的,任何提供电子对的分子被称为路易斯碱。
在精细酸碱反应中,软硬酸碱理论考虑到离子的极化性和离子大小。
无机化合物存在于天然矿物质中。
例如土壤和黄铁矿中含有硫化亚铁,石膏中含有硫酸钙。
无机化合物应用于多个方面:作为生物大分子,作为电解液(氯化钠),作为储能物(ATP)或作为结构骨架(DNA 骨架中的多磷酸盐)。
最重要的人工合成的无机化合物是通过哈伯合成氨法合成的,用于土壤施肥的亚硝酸盐铵。

LESSON 2Properties of Materials材料的特性The properties of a material are those characteristics that help modify and distinguish one material from another.材料的特性是变更和区分一种材料和另一种材料的特征。
All properties are observable and most can be measured quantitatively.所有的特性都是可见的,而且大多数是可以定量测量的。
Properties are classified into two main groups, physical and chemical properties材料特性可分为物理特性和化学特性两大类。
Physical properties involve no change in the composition of the material .物理特性指的是材料成分不发生改变的特性。
Chemical properties are associated with the transformation of one material into another化学特性指的是能够结合一种材料变成另外一种材料的特性。
.Physical properties are, in turn, arbitrarily subdivided into many categories.物理特性,可以被任意地分为许多种类。
These subdivisions bear names such as mechanical, metallurgical , fabrication ,general ,magnetic ,electrical thermal ,optical , thermonuclear ,and electro-optical.这些细类名称包括机械特性,冶金特性,装配特性,通用特性,磁性特性,电子特性Regardless of the name of subdivision ,physical properties result from the response of the materials to some environmental variable ,such as a mechanical force, a temperature change, or an electro-magnetic field. In the following, the mechanical property of materials will be discussed.这些特性是由于材料在环境变化下形成的反应而产生,比如机械力,温度的改变,电磁场。

) Its performance is literally a matter of life and death .(其性能逐渐成为一个生死攸关的问题) It has to withstand being gassed , steamed or zapped with powerful radiation ,and come out nit only being , but looking , antiseptically pure---even if it sits on a shelf for years.(它必须能抵御毒气,蒸汽或防强大的辐射,即使在货架上多年,它不仅要无菌纯洁,而且看起来清洁纯净。
)On top of that , these days medical-device packaging is subject to two sweeping social concerns : the state of the environment and the debate over the cost and availability of health care .(总而言之,现代医疗设备包装受到广泛的社会关注:国家的环境和医疗保健成本和可用性的辩论。
)‘Medical-device makers are like everyone else,’ says Rich Partlow , vice presidents of sales and marketing for Plastofilm Industries Inc.(Rich Partlow,为Plastofilm工业公司的市场营销部副总裁说:“医疗设备制造商和其他人一样,)‘When everyone starts screaming about costs , they’re going to start looking at their supplier and they’re going to start looking internally.’(当其他人开始抱怨成本时,他们将开始关注于医疗器械公司的材料供应商,他们将注重从内部找原因。
