目前採用的遮蓋性干擾的噪聲源主要來自半導體器件本身的熱噪聲或齊納雪崩噪聲，但各器件本身的不一致性和外界條件變化等因素使噪聲輸出質量不穩定;同時由於此類信號不能再生，不利於科學研究。A single station turntable, vertically - split box horizontally - draw type core machine is suitable for mixed core sand which regard hot - firming resin as bond, can make quality core. and it has the merits or easy operation, high productivity, low labor strength, reliable operation, low energy consumption, low noise etc. it is a ideal lot core making equipment
單工位、垂直分盒水平脫芯型射芯機，適合熱固性樹脂為粘結劑的芯砂混和料，能獲得高質量的砂芯，並具有操作方便、生產效率高、勞動強度低、運行平穩可靠、耗能低、噪聲小等優點，是理想的熱法制芯設備。Scroll compressor, used as main engine in auto aircondition system, has small volume, light weight, low noise, low vibration, good seal, high volume efficiency and high heat insulation efficiency
渦旋壓縮機是汽車空調器的製冷主機，具有體積小、重量輕、低噪聲、低振動、密封好、容積效率和絕熱效率高等優點。The disposal of the valves and intake manifold structure not only affect fresh air charge but airflow in the cylinder, which immediately affect combustion efficiency and the performance of dynamic, economic and emission. the structure of the air distributing institution has influence on charging efficiency and the noise of engine. the combustion chamber affects compression scale which has great influence on dynamical performance ; f / v which affects the exhaust of hc ; squash area and clearance which have great influence on the intensity of squash
氣缸蓋的氣門排列方式與氣道結構形式影響進氣充量和氣流在氣缸內的運動，從而影響了燃燒效率，對整機的動力性、經濟性以及排放都有直接的影響；配氣機構的形式影響充氣系數和整機噪聲等；缸蓋燃燒室決定了影響整機動力性能的壓縮比，影響hc排放的f / v和對擠流起決定性作用的擠氣面積以及擠氣間隙，所以燃燒室對整機動力性、經濟性、排放等都有重要的影響；氣缸蓋是整機熱負荷與熱應力最大的部件之一，熱負荷過高將不利於發動機壽命以及可靠性的提高。Least square method is used to eliminate linearity errors of system as result of asymmetric illumination and fitting. averaging method of neighborhood and medium filtering method are used to effectively overcome thermionic noise as result of courses of image transferring, gathering and quantization and so on
對由於光照不均以及安裝等存在的系統線性誤差，採用最小二乘法線性擬合加以消除；對由於圖像採集、傳輸、量化過程中產生的熱電子噪聲，利用了鄰域平均和加權中值濾波方法來有效地減小。Higher - order statistics can deal with either colored noise, non - gaussian, nonlinearities or nonminimum phase, whereas second - order statistics can not. so these methods based higher - order statistics are wide applicable in signal process and system identifications. this paper describes the basic theory and methods based higher - order statistics in applicability of system identification and signal process, introduces and analyses the theoretical and algorithmic results of identifying non - gaussian arma process during recent years
當基於2階統計量（如功率譜、相關函數）的經典辨識方法無法滿足有色噪聲、非高斯、非線性以及非最小相位系統的要求時，基於高階統計量方法越來越受到人們的重視，已經成為系統辨識和信號處理等領域的研究熱點之一。分享友人
