This method is based on the Snell law of acoustic propagation in water. Different velocity gradients among linear layers in water are utilized to draw the sound ray chart, and a mathematical model of the geometric operational range is built. Furthermore, the geometric homing range is predicted with sound ray density, a prediction system of geometric operational range for acoustic homing torpedo is designed and the function of the system is realized through a system software. The sea trial demonstrates the prediction validity of the system.

第五章从几何的观点探索复数的几何性质，包括复数平面、复数的四则运算及复数的n次方根，并举出几个例子，说明这些几何性质如何应用在解决平面几何的问题上。

Concept of compound geometric design for at-grade intersection is presented, and in functional, economic and environmental concept's way at-grade intersection's geometric design is elaborated. Qualitative and quantitative research is provided for intersection's channelized and flared design, including detailed analyses for pocket lane, crossway and traffic island. When conventionally channelized design of signalized intersection isn't possible or these effects are poor, an unconventional geometric design for intersection is brought out and 5 kinds of modes are systematically studied. An example is illustrated to urban signalized intersection compound design's splendid future and deep importance.
