ot all the properties of alkenes are revealed by focusing exclusively on the func- tional group behavior of the double bond. A double bond can affect the proper- ties of a second functional unit to which it is directly attached. It can be a sub- stituent, for example, on a positively charged carbon in an allylic carbocation, or on a carbon that bears an unpaired electron in an allylic free radical, or it can

Absolute configuration(Section 7.5): The three-dimensional Activating substituent (Sections 12.10 and 12.12): A group rrangement of atoms or groups at a stereogenic center. that when present in place of a hydrogen causes a particular Acetal(Section 17.8): Product of the reaction of an aldehyde or reaction to occur faster. Term is most often applied to a ketone with two moles of an alcohol according to the substituents that increase the rate of electrophilic aromatic

Directions: This part is to test you listening ability. It consists of 3 sections Section a: Conversations Directions: In this section, you will hear 10 short conversations. At the end of each mersation, a question will be asked about what was said. Both the conversations and the questions will be spoken only ONCE. After each question there will be a pause During the pause, you must read the four choices marked A), B), C) and D), and decide

设矩阵A∈Rn,如果存在数入∈C及非零向量x∈C满足方程 Ax∈x,则称λ为矩阵A的一个特征值,称为矩阵A的相应于特 征值λ的特征向量。为简单起见,下称,x为矩阵A的一特征对。 特征值的计算,直接从特征方程()=det-A)=0出发会遇到很 大困难,当n稍大一些,行列式展开本身就很不容易,随后是高次代数 方程求解。因此,矩阵特征值的求解,主要是数值解法

Product development has been a major activity in the food industry for over 40 years, but only gradually has it developed as a strategic business area and also as an advanced technology. For a long time it was essentially a craft, loosely related to the research and engineering areas in the company. The pressures for product development came very strongly from the needs of the growing supermarkets for a constantly changing, extensive mix of products and for continuous price promotions. So there was the drive for product difference

Product development management in the food system is complex, long term and capital intensive. It is total company management involving every function in the company- so it is managing either a microcosm of the company or an integration of the company functions. For a major innovation, the company may set up a new venture company or division; or a new group of people may form a new company. At this time when many new companies are being formed on the innovations of information technology and biotechnology, it is interesting to speculate on new venture companies in the food industry and the basis of their new innovations. But at the present time

Product development does not occur in isolation as a separate functional activity. It is a company philosophy, a basic company strategy and a multifunctional company activity. In recent years to show this all-encompassing basis, bringing together product, process, marketing and organisational innovations, there has been development of an overall innovation strategy. This innovation strategy is related to the company's overall business aims and strategy, as well as the social, economic and technological environment, and the company's own knowledge and skills. The business strategy also includes a duct strategy outlining the products of the future. The combination of the innovation and product strategies is the basis for the product development strategy, and from this can be developed
