To some special data , the compressing ratio of the existing arithmetics may be very high , but to others , it may be very low 各種壓縮算法在一定程度上說都具有個性,他們對某一類型的數(shù)據(jù)其壓縮率可能很大,但對于另一類型數(shù)據(jù)其壓縮率則可能很小。
A study is on relation to compressed ratio and power character . though platform test and calculation they compared and analyzed the refitted engine performance 研究了壓縮比與天然氣發(fā)動機動力性的關(guān)系,計算分析天然氣發(fā)動機在不同壓縮比下的動力性。
And the paper will tell you the optimized value of the compressed ratio . the cng engine also performances well on emission . it is priority to original one in all aspects 課題研究了在不同的工況下,改造后天然氣發(fā)動機ch 、 co 、 nox 、 co2排放特性,并與原機進行了比較。
Through these improvments , the arithmetic of lzssb is succeeded in the running on the existing communication plat . its compressing ratio and real - time are all meet the need of the project 將所選的lzssb算法經(jīng)過上述改進后,成功的在現(xiàn)有的通信平臺上運行,其壓縮率與實時性都滿足了要求。
The major factor considered in experiment are followed : the influence of width of wall , the influence of different reinforcement ratio of wall , the influence of axis compress ratio , the influence of mortar layer 試驗中考慮的主要因素有:墻體厚度對于抗震的影響、墻體不同配筋的影響、軸壓比的影響、砂漿層的影響等。
The ninth chapter analysed irreversibility of each component based on air - conditioning simulation . it indicated that the reason why exergy destroyed is caused is compressed ratio , superheated temperature and subcooled temperature 基于仿真對空調(diào)系統(tǒng)各部件的不可逆性進行了分析,結(jié)果表明,壓縮比、過熱度、過冷度是導(dǎo)致(火用)損的主要因素。
The second method debases the compressing ratio , but it decreases the runing time of the program because it lessens the complication of the program . through this , the other programs can get bigger running space 第二種方法雖然在一定程度上減小了壓縮率,但是因為減小了程序的復(fù)雜度,從而減小了程序執(zhí)行時間,給其他數(shù)據(jù)處理提供了更大的運算空間。
So two buffers of different size are setup to convert the outside data to meet the request of dsp , and through this method , the compressing ratio is increased . ( 2 ) deal with the end sign of the datum 在程序中設(shè)置了兩個存儲空間大小不一樣的緩沖區(qū),通過外圍數(shù)據(jù)的轉(zhuǎn)換,來滿足程序中8bit的比較要求,從而大大提高了壓縮率( 2 )數(shù)據(jù)流結(jié)束標(biāo)志的處理。
In contrary to the brushlet , the ezw ( embedded zerotree wavelet coding ) algorithm is also discussed . the performance of brushlet in preserving the high frequency information at high compress ratio can be revealed when compared to the ezw algorithm in the result 作為對比,本文同時研究了ezw小波系數(shù)零樹編碼算法,從對比中可以看出brushlet在高壓縮比下保留圖象高頻信息的性能。
Zerotree makes use of the relativity of child band , which is a meaningful breakthrough based on wavelet image compress coding . ezw and spiht algorithms based on zerotree structure , which enhance the image compress ratio largely , are discussed and analyzed in detail 在小波系數(shù)的壓縮方法中,小波系數(shù)的零樹方法充分利用了相應(yīng)子帶間的相關(guān)性,是基于小波圖像壓縮編碼的一個有意義的突破。
