CLAP preprocesses some of the data extracted from the database by random sampling technique, which decreases the running time greatly. 該算法采用隨機抽樣技術(shù)，從數據庫中抽取一部分數據進(jìn)行聚類(lèi)的預處理過(guò)程，這樣大大降低了運行時(shí)間。
The quadrat sampling technique is mostly used in plant ecology to study the distribution and abundance of species in plant communities. 其內部的生物體被標記，樣方抽樣技術(shù)多用于植物生態(tài)學(xué)領(lǐng)域，用來(lái)研究某一植物群落中物種的分布及其含量的多少。
