1. Green Chemistry is the design, development, and implementation of chemical products and processes to reduce or eliminate the use and generation of substances hazardous to human health and the environment. Unlike regulatory requirements for pollution prevention, Green Chemistry is an innovative, non-regulatory, economically driven approach toward sustainability. Green Chemistry considers the entire life cycle of chemical processes as an opportunity for design innovation. Rather than regulatory restrictions for controlling hazards, Green Chemistry challenges innovators to design and utilize matter and energy in a way that increases per formance and value while protecting human health and the environment. （20 分）

2. The unit operations are as applicable to many physical processes as to chemical ones. For example, the process used to manufacture common salt consists of the following sequence of the unit operations: transportation of solids and liquids, transfer of heat, evaporation, crystallization, drying, and screening. No chemical reaction appears in these steps. On the other hand, the cracking of petroleum8, with or without the aid of a catalyst, is a typical-chemical reaction conducted on an enormous scale. Here the unit operations —transportation of fluids and solids, distillation, and various mechanical separations —are vital, and the cracking reaction could not be utilized without them. The chemical steps themselves are conducted by controlling the flow of material and energy to and from the reaction zone. （20分）

3.Chemical engineering is above all based on the chemical sciences, such as physical chemistry, chemical thermodynamics, and chemical kinetics. In doing so, however, it does not simply copy their findings, but adapts them to bulk chemical processing. The principal objectives that set chemical engineering apart from chemistry as a pure science, is “to find the most economical route of operation and to design commercial equipment and accessories that suit it best of all”. Therefore, chemical engineering is inconceivable without close ties with economics, physics, mathematics, cybernetics, applied mechanics, and other technical sciences. （20分）

4.The modern era of polymer science belongs to the chemical engineer. Over the years, polymer chemists have invented a wealth of novel macromolecules and polymers. Yet understanding how these molecules can be synthesized and processed to exhibit their maximum theoretical properties is still a frontier for research. Only recently has modern instrumentation been developed to help us understand the fundamental interactions of macromolecules with themselves, with particulate solids, with organic and inorganic fibers, and with other surfaces. Chemical engineers are using these tools to probe the microscale dynamics of macromolecules. Using the insight gained from these techniques, they are manipulating macromolecular interactions both to develop improved processes and to create new materials.（20分）

5. Industrial waste treatment. The hazardous organic components in industrial wastewater could be destroyed with thermocatalytic or photocatalytic processes. A promising line of research employs “supercritical” water athigh temperatures and pressures. Under these

conditions, water exhibits very different chemical and physical properties. It dissolves reactions of many materials that are nearly inert under normal conditions. （20分）

汽车专业英语期末考试题型说明

Terminal Reviews to English for the Automotive Profession I. Answer the following questions.(20%) Choose 5 of 6, 4 points for each, total in 20 points. 1. What does the drive train consist of? The drive train consists of clutch, transmission, driveshafts, differentials, and the final drive (drive wheels, continuous track like with tanks or Caterpillar tractors, propeller, etc.). In a wider sense, the drive train includes all of its components used to transform stored (chemical, solar, nuclear, kinetic, potential, etc) energy into kinetic energy for propulsion purposes. 2. How to install the drive gear? First, clean the drive gear attaching bolts. Second, remove the adhesive adhered to the threaded holes of the drive gear by turning the special tool, and then clean the treaded holes by applying compressed air. Third, apply the specified adhesive to the threaded holes of the drive gear. Forth, install the drive gear onto the differential case with the mating marks properly aligned. Tighten the bolts to the specified torque in a diagonal sequence. 3. What is the process of the ABS working? The Anti-lock Brake System (ABS) uses a sensor that know when one wheel (or a pair of wheels) is skidding. The sensor sends a signal to a computer, which signals a modulator valve. The modulator connects into the hydraulic system and can momentarily release the brake pressure and prevent the wheels from locking. (The pressure release is so fast that a driver is seldom aware of it.) Pressure is then reapplied until the sensor again sensor that the wheel is about to lock up. Thus, this system keeps the wheels as colse to lock up as possible, without actually allowing the wheels to lock up and skid. This is called incipient lock up. Maximum braking occurs at that point. 4. What is the purpose of gear reduction from steering gear? The gear reduction is known as steering gear ratio. This is needed to reduce the amount of effort required to turn the steering wheel, particularly when parking. During straight-ahead driving, this also reduces the possiblility of oversteering. The ratios vary considerably, depending largely on vehicle size and weight. Larger, heavier vehicles require a graeter reduction in manual steering gears. 5. How does the starter clutch work? The purpose of the starter clutch is to engage and disengage the pinion gear from the flywheel. When the starer is cranking, the pinion gear slides on the armature shaft and engages the flywheel. 6. How to check DTC in the normal mode? First, turn ignition switch off. Second, connect terminals TE1 and E1 of data link connector 1 or 2. Third, Turn ignition switch on. Forth, read the diagnostic trouble code on malfuntion indicator lamp on the combination meter. Fifth, afer completing the check, turn ignition switch off and disconnect terminals TE1 and E1. II. Translate the following into Chinese. (20%) Choose 20 of 30, 1 points for each, total in 20 points. 1. drive train 动力传动系 2. suspension system and axle 悬挂系统和驱动桥 3. brake system 制动系统 4. steering system 转向系统
