Effect of infrasound on lung oxygemation and lung damage in rats 次聲對大鼠肺組織損傷及肺氧合功能的影響
Effects of infrasound on biological characteristics of osteoblast - like cells 次聲波對成骨樣細(xì)胞生物學(xué)特性的影響
Infrasound monitoring system 次聲監(jiān)測系統(tǒng)
Change and significance of gfap in the brain of mice exposed to infrasound 不同聲壓級次聲作用小鼠后腦膠質(zhì)纖維酸性蛋白的含量和意義
Using the infrasound method to predict the initial time and scale of the earthquake is effective 利用次聲波異常信號預(yù)測發(fā)震時間及震級是十分有效的。
Being inaudible and with a mechanism of bio - resonance , infrasound has a brilliant perspective when applied to biomedicine 次聲的作用機(jī)理是生物共振,次聲應(yīng)用于生物醫(yī)學(xué),前景將會十分廣闊。
Furthermore , the above recording data limited to a single point is not valid to predict the epicenter . in this thesis , seismic infrasound is profoundly studied 本課題正是在以上的前提下,對臨震異常次聲進(jìn)行更深一步的研究和探討。
An infrasound detecting software was developed in visual c + + . it is a real - time infrasonic data acquisition and analysis program of 3 - point array 最后用visualc開發(fā)一套次聲波探測系統(tǒng)軟件,實現(xiàn)3點陣次聲信號的實時數(shù)據(jù)采集和分析。
With the correlation technique , direction and speed of the infrasound can be calculated by computing the time delay of each detector and by using geometric knowledge 利用互相關(guān)技術(shù),計算信號在不同傳感器上的時間延遲,再由平面幾何原理,得到波的方位和波速。
At present time , the infrasound method stays the stage of using recorders to record the infrasound wave continuously for 24 hours . automatically data acquisition and computerized analysis is not available 目前次聲波采用記錄儀連續(xù)24小時觀測記錄其波形,還未實現(xiàn)數(shù)據(jù)的自動采集,所以無法利用計算機(jī)對信號進(jìn)行分析處理。
Infrasound, sometimes referred to as low-frequency sound, is sound that is lower in frequency than 20?Hz (Hertz) or cycles per second, the "normal" limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high.
