小波变换是信号的时间-频率分析方法，它具有多辨分析的特点，它能有效地检测和识别跳频信号，在跳频通信中有极其重要的作用。
To analyze and detect the feature of frequency hopping signal exactly is a crucial prerequisite to carrying out disturbance to follow the track of signal.
一种不错的做法是，从512 MB开始，然后逐步向上或向下，以确定最优值、测定吞吐量或响应时间，并分析gc日志，以了解进行清除操作的频率及时间。
A good starting point would be 512mb, then move up or down to determine optimal value, measure throughput or response times, and analyze GC logs to understand frequency and length of scavenges.
研究人员分析了所有来访者振动的频率、持续时间以及幅度。
Then the researchers analyzed the frequency, duration and amplitude of each visitor's vibrations.
