Abstract: The present invention discloses a globally universal key factor preset array platform for dynamic forecast analysis of biological populations, which can be used to preset massive arrays of standard environmental factors; and through the Internet user's registration system, global users for biological population dynamic forecast can instantly select the contents suitable for their own country or local region to construct an accurate statistically forecast model for specific area and specific biological population dynamics, so as to make an accurate quantitative forecast of biological population dynamics in the future. Each preset data is co-located by a row variable coordinate and a column variable coordinate. Each located individual data can not be interchanged up and down or to and fro, the row variable coordinate is time coordinate and the column variable coordinate is space coordinate.

Abstract: A water dancing speaker is disclosed. The water dancing speaker comprises a housing assembly, a liquid spraying device, a liquid spraying power supplying device, a liquid column steering device, a driving device and an audio device. The housing assembly is formed with an exhibiting cavity, a partition cavity and an audio cavity, and the liquid spraying device can produce a liquid column. The water dancing speaker of the present disclosure can produce liquid columns that vary rhythmically with the audio characteristics of the played tracks, which improves the ornamental effect of the speaker.
