如果扰动比一个简单声波强,其引起的波前就会比马赫波强产生一 个与来流夹角为β的斜激波,且β>μ。这一比较在图9.4中给出。然而, 斜激波产生的物理机理与上面描述的马赫波的产生完全相同

Chapter 3 Kinematics I: rectilinear motion Motion implies change, and it is change make life-and physics-visible and interesting. Kinematics is the theory about the description of motion. Physical theories are creations of the human intellect; they must be invented rather than discovered

2.1 scalar and vector quantities 1. scalar Physical concepts that require only one numerical quantity for their complete specification are scalar quantities. 2. vector Vector quantities require for their complete specification a positive quantity, called the magnitude of the vector and the direction otice:Not all things with a magnitude and direction are vectors
