(Para.1)Paraphrase: The games it (game theory) studies extends from chess to child bringing-up and from tennis to handovers.range: v. to vary between limits, extend, run in a linee.g. (1) The price ranges from $ 30 to $ 80. (2) The boundary ranges from north to south.takeover: n. the act or an instance of assuming control or management of or responsibility for sth. 接收、接管e.g. The economy of Hongkong goes well after its takeover.

The current calibration methods of the projectilevelocity measurement system are introduced, and the problem and the unreasonableness of these methods are analyzed. Based on the principle of the mathematical statistics, the calibration method is investigated that measures the projectile-velocity at the same time by the multi-group zone-block device is unbiased, uniform and efficient and uses the average of the measured value as the true value of the projectile-velocity at the point.
