Passage 2 University Physics is intended for students of science and engineering. Primary emphasis is on physical principles and problemsolving。 historical background and specialized practical applications have been given a place of secondary importance. Many workedout examples and an extensive collection of problems are included with each chapter. In this new edition, the basic philosophy and outline and the balance between depth of treatment and breadth of subjectmatter coverage are unchanged from previous editions. We have tried to preserve those features that users of previous editions have found desirable, while incorporating a number of changes that should enhance the book39。s usefulness. 中國最大的管理資料下載中心 (收集 \整理 . 部分版權(quán)歸原作者所有 ) 第 15 頁 共 42 頁 The textbook is adaptable to a wide variety of course outlines. The entire textbook can be used for an intensive course two or three semesters in length. For a less intensive course, many instructors will want to omit certain chapters or sections to tailor the book to their individual needs. The arrangement of this edition facilitates this kind of flexibility. Conversely, however, many topics that were regarded a few years ago as of peripheral (外圍的 )importance and were omitted from introductory courses have now e to the fore again in the life sciences, earth and space sciences, and environmental problems. An instructor who wishes to stress these kinds of applications will find this textbook a useful source for discussion of the appropriate principles. In any case, it should be emphasized that instructors should not feel constrained (受約束的 )to work straight through the book from cover to cover. Many chapters are, of course, inherently sequential in nature, but within this general limitation instructors should be encouraged to select among the contents those chapters that fit their needs, omitting material that is not relevant to the objectives of a a particular course. 6.

Each evening at twilight, many times an evening in fact, a pair of them will leave the safety of their Caribbean reef and rush a few yards off the seafloor. Positioning themselves sidetoside, headtotail they hurriedly release their eggs and sperm. Then they turn sharply for home, leaves their gametes to mix in silence. Ichthyologist Phillip Lobel of the Woods Hole Oceanographic Institution has found that hamlet fish and many other fish emit“cries of ecstasy at the appropriate moment. Biologists have long known that a few fish make sounds. The toadfish, for example, is named for its low call, which can be heard even above water. Underwater, however, human ears don39。t work well. As a result researchers didn39。t notice how mon fish calls were until Lobel started diving with a video camera and an underwater microphone like the kind the Navy uses to listen for submarines. Lobel has learned that the fish playing the role of the malehamletifish switches roles from one tryst to the nextemits a series of short, low sounds. The
