81-1 Introduction 1 Circuit models(模型) The voltage source Two active(有源) models The current source The resistor Three passive无源) models The inductor The capacitor

In the chapter, we shall define the basic active and passive circuit models, explain power conventions and determine when power is delivered and absorbed, state Ohm's law and Kirchhoff's law, determine the equivalent resistance of a passive circuit containing only resistors

The packaging sector is an important global industry, representing about 2% of the Gross National Product (GNP) of the developed countries. The value of the packaging industry is about 345 million euros worldwide, of which Europe represents a third. Fifty per cent of this market is packaging for food. Forecasts suggest that the sector will continue to grow in size and importance Many cooking and preservation processes still largely depend on effective packaging, for example canning, aseptic, sous vide and baking processes. Processes such as drying and freezing would be lost without protective packaging after processing to control product exposure to the effects of oxygen light, water vapour, bacterial and other contaminants. However, modern food packaging no longer has just a passive role in protecting and marketing the product. It increasingly has an active role in processing, preservation

Fresh fish products are usually more perishable than most other foodstuffs due to their high aw, neutral pH, and presence of autolytic enzymes. The spoilage of fish and shellfish results from changes caused by oxidation of lipids, reactions due to activities of the fishes'own enzymes, and the metabolic activities of microorganisms (Ashie et al., 1996). The rate of deterioration is highly temperature dependent and can be inhibited by the use of low storage

Constructivism are based on the idea that, unlike a computer disk or an empty container, students do not wait passively to be filled up with knowledge. Rather, students actively build, or construct, their own knowledge.Teachers cannot entirely control their students’ learning, expert teachers can do much to facilitate students’ own active learning processes

ntroduction 2004 has been a very active and productive year for the multilateral trading system, both in terms of progress in the Doha Development Agenda(DDA)as well as in the WTOs regular work. These developments have taken place against the backdrop of a much healthier global economy. The DDA was given an important boost with Members' decision in July
