他按照手錶秒針跳動的節奏,計算著蹬車的頻率。Even under the condition that the filling pressure was up to 1. 5mpa, the onset temperature was only 237 ?. with the filling nitrogen of 0. 9 mpa, the maximal pressure ratio reaches 1. 21 and the operation frequency is 25 hz. the ratio of the harmonic wave of the engine was very little and the frequency jumping was not found in present experiments
在充氣壓力為0 . 9mpa的條件下,該熱聲發動機最大壓比可達1 . 21 ,遠高於駐波型熱聲發動機,實驗結果和理論分析均表明系統的工作頻率為25hz左右,實驗裝置的諧波比例非常小,且也沒發現頻率跳變等現象。Intermodulation suppression for fh ( frequency hopping ) receiver is designed by selecting the intermediate frequencies and changing group of filters, local oscillation ( lo ) frequency, bandwidth of lo frequency under the condition that receiver configuration, sensitivity, dynamic range, instantaneous bandwidth and precision of frequency measurement are fixed
摘要針對跳頻接收機的體制和靈敏度、動態范圍、瞬時工作帶寬、測頻精度等設計參數,通過改變預選器組成、本振頻率和本振帶寬,分析接收通道的中頻選取原則,以實現跳頻接收機的互調抑制設計。The heartbeat is the frequency that points to heart throb, namely minutely jumpy how many times
心率是指心臟搏動的頻率,即每分鐘跳動多少次。The new technology of non - contact life - parameter detection is relative to that of the normal contact one, which uses microwave beams to illuminate the human subject, whose reflected wave will be modulated by the surface movement resulting from the physical activity. by this way, some parameters of the reflected wave, such as frequency and phase will be changed. if these changes can be detected, the life parameters such as respiration rate and heartbeat rate will be extracted from those changes
非接觸生命參數檢測是相對于常規的接觸式檢測而言的一種新技術,它利用微波束照射人體,其回波信號被人體生命活動引起的體表微動所調制,使得回波信號的某些參數(如頻率、相位)發生改變,檢測到這些變化就能從中提取出人體的生命參數(如呼吸或心跳) 。At large attack angle the frequency of the vortex has n ' t a apparent zone of " lock - in ". the fluid - induced vibration at large attack angle belongs to the stable dynamic response problems. but a sudden skip of amplitude will occur at large inlet velocity
在大攻角下分離渦脫落的頻率沒有一個明顯的頻率鎖定區域,流體振動屬于穩定的動力響應問題,但在大來流速度下會出現振幅突跳的現象。A infrared system with which can detecte the pulse of human. because human body are semitransparent, and the transparence of it change along with the heart beat. the infrared sensor can detecte the change, we may tanslate the signal from sensor into a digital form by a cmos ic. when the signal change into a digital form, another ic can get the rhythm of the heart from the analog ic. this article designed the anologe ic which got the sensor signal into digital form
本論文完成了一個基於反射型紅外線傳感器的cmos模擬專用集成電路的設計,它構成的紅外系統具有探測心跳頻率的功能。設計根據人體組織的半透明度會隨心臟跳動而變化的特點,由傳感器探測到這一變化,通過專用集成電路將信號放大並利用,獲得心跳頻率。本模擬晶元結合數字電路可計算即時心率或統計心跳總數。Blood samples will be taken and the levels of nutrients in these samples correlated with prisoners ' “ impulsivity ” and the variability of their heart rates
血樣採集后,在這些樣品中營養物的水平和囚犯的沖動以及心跳變化的頻率將會聯系起來。Every few milliseconds, a fhss signal bounces between different specific points in a designated " spread " of the electromagnetic spectrum, reducing interference from other signals and making it very difficult to eavesdrop on the transmission
每隔幾毫秒, fhss信號在指定「擴展」的電磁頻譜的不同頻率點上跳動,減少其它信號的干擾,使它在傳輸中難以被竊聽到。The study on query system using the basketball video fragments as an example is involved in such areas : first, in the condition of " video - flash " and " jump " phenomenon, the " two - level video segmentation algorithm " solves the mistaken detection of the shot edge ; second, the part or the whole video as the result of detection can be well played ; third, the text on the complex background can be detected and fixed, not only the speed but also the right proportion have been improved ; forth, the text can be divided into " regular detection " and " irregular detection "
本課題以籃球比賽的視頻片斷為例,主要進行了以下幾個方面的研究: 1 )針對視頻中的「閃動」和「急跳」現象,提出了「二級鏡頭分割演算法」 ,解決了鏡頭邊緣的誤識別問題。 2 )對所檢測出的視頻片斷或整個視頻流進行播放。 3 )基本解決了復雜背景下文字檢測與定位問題,提高了數字的識別速度與正確率。The clock used should be free from significant phase or frequency jitter
