The sound speed distribution of ocean is not uniform, so the sound ray is often curving because of refraction when sound transmitting through the sea channel. this means the time delay between the transmitter and the receiver is larger than the time delay between them in the condition that the sound ray is straightaway, then positioning error is caused
海洋中聲速分佈是不均勻的，因此由於折射效應，聲音在海洋通道傳播過程中其聲線是彎曲的，聲線彎曲意味著聲信號從發射點到接收點的傳播時延大於聲信號直線傳播的時延，致使定位產生誤差。 -
Secondly, it is shown that the system with time delay is uniform persistent under some appropriate conditions, and suf cient conditions are obtained for the global stability of the unique positive equilibrium point of the system with time delay
而後討論具時滯參數之競爭系統，在適當條件下系統之解是均勻持久的，進而得到此系統之唯一正均衡點的整體穩定性的充分條件。 -
