According to the existing hours of this lesson, we mainly explain rudimentary knowledge relevant to inorganic chemistry, including colligative property of diluted solution and four balances (Acid-base equilibrium, precipitate-dissolve equilibrium, oxidize-reduce equilibrium and coordinate equilibrium) and two structures (atomic structure, molecular structure ).

从而为后续分析化学，有机化学，物理化学及相关专业课程的学习打下必要的基础。因此，根据现有的实际课时数，主要讲解有关的基础知识。包括稀溶液依数性和四大平衡(酸碱平衡，沉淀-溶解平衡，氧化-还原平衡，配位平衡)，二大结构。

Zn-diffused high power 650 nm AlGaInP/GaInP material with compressively strained multi-quantum-well active layer was fabricated. The zinc diffusion was used on the material facet in a sealed quartz tube. Photoluminescence spectra shows 175 meV blue-shift in the Zn diffusion area, which is transparent for 650 nm laser emission.

利用石英闭管法对金属有机化学气相沉积外延生长的应变量子阱650 nm AlGaInP/GaInP材料进行选择区域扩Zn，使扩Zn区域的光致发光谱的峰值蓝移达175 meV，形成对650 nm波长激光器的高透腔面，有益于减少激光器腔面光吸收，增加了激光器退化的光学灾变损伤阈值。

The sequence of chapters in Study Guidance is the same as the book Organic Chemistry written by lv yixian(7th edition), and this column summarized the study goals,requirements,knowledge points,unode and nodus briefly,which will make students easy to learn, master and comprehend.

学习指导》栏目的章序与吕以仙主编的《有机化学》第七版相同，简明扼要地归纳总结了各章的学习目的要求；知识点；重点与难点。使学生对本章所要学习、掌握和了解的内容一目了然。

Occasionally, customs agents accepted large tips from Teabing in exchange for turning a blind eye to the transport of harmless organics—mostly luxury foods—French escargots, a particularly ripe unprocessed Roquefort, certain fruits.

这里的海关工作人员不时会从提彬那里得到大笔的小费，作为交换，他们对他从外地运来的无害有机化学物——其中多半是些奢侈食品，如法国食用蜗牛，特别是宜于食用但尚未加工的羊乳干酪，还有一些水果——睁一只眼闭一只眼。

During the Great Proletarian Cultural Revolution, a "three-in-one" combination research group was organized from the workers, which formed the main-force, cadres and technical staffs of Silicen-Steel Sheet Works, Metallurgical Designing Institute and a research institute, for the recovery of sulphuric acid from the waste acid liquor of the steel works.

在无产阶级文化大革命中，由上海矽钢片厂、上海冶金设计院及中国科学院上海有机化学研究所组成的以工人为主体的工人、干部、科技人员三结合试验小组，对硅钢片酸洗废液通过用S-203强碱性阴离子交换膜扩散渗析法进行硫酸的回收，既节约物资，又改善环境，获得了较为满意的结果。

Ring expansion reactions are important tools in organic synthesis which take advantage of existing ring structures and avoid the unfavorable factors associated with other approaches in the construction of medium and large rings.

自由基成环和扩环反应是有机化学中的重要反应，它可以利用已有环的结构来构筑所需要的中环和大环，避免其他一些不利的竞争反应。
