energy from nutrients into ATP, and then release waste products.
光合作用以二氧化碳和水为原材料并经历两步化学反应。
第一步，称光反应，水分子裂解 (被氧化)，释放氧气，并形成ATP和 NADPH（还原型烟酰胺腺嘌呤二核苷酸磷酸）。
此反应必须在存在光能的条件下进行。

Introduction
光合作用只发生在含有叶绿素的绿色植物细胞、藻类、某些原生生 物和细菌之中。
总体来说，这是一个将光能转化成化学能的过程，其能量以分子 键形式贮存。
从化学和能量学角度来看，它是细胞呼吸作用的逆反应。
但是细胞呼吸作用是高度放能，释放能量的过程，而光合作用需 要能量, 并且是高度吸能的过程。
在光合作用的光反应中，当捕光分子回到基态时，额外的激发能 被转移到其它分子中并且以化学能的形式贮存。
•All photosynthetic organisms contain various classes of
chlorophylls and one or more carotenoid pigments that also contribute to photosynthesis.
captured by biological molecules to do constructive work.
生物分子能捕获可见光谱中光子的能量。
The pigment chlorophyll in plant cells absorbs photons within a particular absorption spectrum—a statement of the amount of light absorbed by chlorophyll at different wavelengths.

Section A Steel Structure
3-1.One of the visible changes on steel structure is the remarkable trend towards greater use of space structures; this trend is growing as a result of architectural preference. This is partly due, no doubt, to reaction from beam-column systems of previous decades, but also due to the realization of the advantages of spaces structures.

Section A Steel Structure
1. Steel structure refers to a building in which steel plays the leading role. The early development of high-rise buildings began with structural steel framing. With the development of science and technology, the types of steel structure is growing. Steel frame building and space structure are within it.

Section A Steel Structure
4.There are various types of space structures, differing in their behavior under load and requiring different methods of analysis. Double-layer grids are typical examples of space structures and also one of the most popular forms of space frames; they are frequently used nowadays all over the world for covering large-span industrial buildings, sports halls, churches, and exhibition centers.
