Inertia is a very important concept in Understanding of inertia， the more recognition of objects with properties of keeping original motion state， the inertia (object will remain at rest or of uniform motion in a straight line)， the nature of reason is not in the interior of the object， also has nothing to do with But due to the uniformity of the object of time and space Along with the development of modern physics， general relativity and proposed that inertia is around by its expression objects associated with space-time quality distribution determines the nature of the An important progress for inertial understanding of relationships with energy and With inertial energy point of view to broaden the understanding of inertia， also broaden the understanding of Based on inertial essence as the research perspective， this paper expounds on inertia of the concept of development and change， human understanding of nature of various inertial phenomenon to broaden the understanding of inertia， focusing on the based on the Newton classic time-space conditions to explore the establishment of the law of inertia and the inertia in the high school physics teaching concept， the law of inertia， grasps the inertia and life closely related， introduces the application of inertia on the science and
Quantum information science is quantum mechanics and information product of the combination of science， including quantum cryptography， quantum communication， quantum computation and quantum In recent years， quantum information science in theory and experiment have made an important breakthrough， caused by governments， industry and IT industry Quantum mechanics in the peculiar physical phenomena in the field of information has a unique feature， in improving the computing speed， the protection of information security， increasing information capacity and improve the detection accuracy can be a breakthrough in the current information system of the classical The use of the basic principles of quantum mechanics and characteristics of a classic can solve some cases can not solve
It is the outcome that quantum mechanics and the information sciences combine together that the quantum information learn， including the quantum password， quantum correspondence， quantum to compute to measure with in recent years， the quantum information learns to all obtained the importance to break on the theories and experiments， cause the high value of all countries government， science and technology field and the information industry the unusual physics phenomenon of quantum mechanics is has the special function in the information realm， under the condition of raising to compute the speed， guarantee information safety， enlarge the information capacity and raising to examine the accuracy， wait can break the extreme limit of the existing classic information make use of the basic principle and characteristics of the quantum mechanics can nicely solving the classic some hard nut to cracks that can't
The application of CAI courseware for teaching reform， create conditions to improve the teaching effect of plays a large role in This paper discusses the CAI courseware in middle school physics experiment teaching assistant， limitation and the advantage of the In order to use just CAI courseware teacher has a certain help for the use of CAI courseware， have a good knowledge and Keywords: CAI courseware， advantage， limitations
