An air compressor is a machine that takes in air at atmospheric pressure and delivers it at a higher pressure. Air compressors are used in several areas such as commercial businesses, jet engines, as well as in the Manufacturing, Chemical, and Petroleum industries. They are classified into three major types based on the design and principle of operation into piston compressors, screw compressors, and centrifugal compressors.The Air Compressor market in China is expected to grow at a rapid rate during the period 2012-2016. This is mainly attributed to the increasing urbanization and industrialization in the country.As a result, China is expected to play a major role in growth of the Global Air Compressor market during the next few years. The Air Compressor market in China is expected to grow at a CAGR of 14.84 percent during the forecast period.

Construction equipment allows the construction of complex high-quality infrastructure in an efficient, accurate, easy, and cost-effective manner. It assists engineers and building promoters in constructing residential, commercial, and industrial buildings and infrastructure rojects such as roads and railways in reduced time. Therefore, construction equipment has been adopted by companies across China for the construction of high-quality buildings and infrastructure.Furthermore, construction equipment is exported from China to companies across the globe as it is often more cost-effective than the construction equipment available in other countries. The Construction Equipment market in China is one of the country's rapidly-growing engineering markets. Several local and international vendors are present in the market. Some of the prominent vendors in the market are Zoomlion Heavy Industry Science & Technology Development Co. Ltd., Sany Group Co. Ltd., XCMG Group, and Komatsu Ltd. The market is expected to witness an improvement in its growth rate and post a CAGR of 24.23 percent during the period 2012-2016.

Biofuels are fuels produced from biomass and waste materials. There are different forms of biofuels, namely fuel pellets (solid), bioethanol and biodiesel (liquid), and biogas (gaseous).Fermentation is the most widely used method for biofuel production; however, other methodsare also used to produce biofuel. One of the major factors increasing the demand for biofuel isthe wide use of ethanol and biodiesel.The Biofuels market in Chinais expected to experience a moderate growth rate during theperiod 2012-2016. This moderate growth is mainly due to the increasing need to reduceemissions. The Biofuels market inChinais expected to grow at a CAGR of 16.88 percent duringthe period 2012-2016.

Industrial robots are programmable, automatically operated machines (or robot systems) that have been developed to replace human effort in industries. The use of robot systems or industrial robots in the manufacturing processes of industries such as Automotive, Food and Beverage,and Electronics constitutes the field of industrial robotics. Industrial robots are programmed to automate and control manufacturing processes. They are used in applications such as welding,painting, assembly, product inspection, testing, and packaging. There are several types of industrial robots, including SCARA robots, articulated robots, cartesian robots, and cylindrical robots. Each robot has a unique set of capabilities that can be used in various industrial applications. In the Food and Beverage industry, industrial robots are used for palletizing, cutting,stacking, handling of materials, and packaging.The Industrial Robotics market in China is growing at a steady rate. It is one of the most significant contributors to the Industrial Robotics market in the APAC region. The Industrial Robotics market in China is expected to grow at a CAGR of 4.97 percent during the period 2012-2016. This is mainly because of the growing demand from the discrete manufacturing industries such as the Automotive industry and the Electrical and Electronics industry to enhance the productivity of the manufacturing process.

抗体作为机体免疫应答的效应分子，能够识别、中和或清除诱发疾病的抗原。抗体的“可变区”（Fab）可特异性地结合抗原或靶细胞；抗体的“恒定区”（Fc）介导多种细胞效应功能（CDC、ADCC等）。此外，Fc端与FcRn的结合，使得抗体分子在体内的半衰期长达10～20天。以上抗体的分子结构与生物功能保证了其作为治疗性蛋白的药用疗效。截至2012年底，欧美市场已有总计30余种治疗性抗体上市销售。抗体药物已经在免疫性疾病、癌症等治疗领域取得巨大成功。而从抗体药物的研发线来看，已经有300余种单抗药物进入临床研究阶段。抗体药物研制的成功率（20%）远远高于传统小分子化学药（11%）。所以，抗体药物已经成为，并且未来仍将是制药行业发展的重要方向。
