The karyotype of caragana microphylla lam can be espressed as 2n = 16 = 16m ( 4sat ) ; the chromosome number of c. intermedia kuang et h. c. fu is 2n = 18. the karyotype of c. intermedia kuang et h. c. fu can be espressed as 2n = 18 = 16m ( 4sat ) + 2m ; the chromosome number of c. arborescens ( amm. ) lam is 2n = 20. the karyotype of c. arborescens ( amm. ) lam can be espressed as 2n = 20 = 20m ( 4sat ) ; from the conclusion one and two, we can guess : the c. intermedia kuang et h. c. fu ' may be the hybrid or intermediary genve between caragana microphlla lam and c. arborescens ( amm ) lam, also may be have different haploid chromosome number
( 2 )可得出三種染色體核型:小葉錦雞兒的染色體數為2n = 16 ,其核型公式為2n = 16 = 16m ( 4sat ) ;中間錦雞兒的染色體數為2n = 18 ,其核型公式為2n = 18 = 16m ( 4sat ) + 2m ;樹錦雞兒的染色體數為2n = 20 ,其核型公式為2n = 20 = 20m ( 4sat ) ,結合形態學所得結論,可推測:中間錦雞兒為小葉錦雞兒和樹錦雞兒的中間類型或雜交種,也可能是具有遞增染色體基數的不同種。She had selected a little bouquet of one brilliant and two or three delicate flowers, relieved by a spray of dark verdure.

同時又有人指出在發生凶殺的房間窗戶上方的石像那雕刻出的鼻子有了兩個小小的窩兒。這窩兒人人認得,可過去就沒有人在石像上見過。偶然會有兩三個衣衫襤褸的農民從夥伴群中走出來窺看變作了石像的侯爵大人,並伸出精瘦的指頭指指戳戳鬧個分把鐘,然後又跟夥伴們一起踏著苔蘚和樹葉逃走了,像些野兔一樣一野兔倒比他們幸運,可以在林莽中活下去。In recent years, with the rapid introduction and commercialization of lchinense vai. rubrum, there comes many confusion concerning the identity of cultivars. in this study, the morphological traits of 21 accessions of lchinense var. rubrum were investigated in spring, autumn, summer and with 2 more accessions in autumn. clustering analysis with average distance was processed for the main traits of leaf and flower using dps ( data processing system )
本文對紅?木的21個變異類型作了春、夏、秋三季形態調查(秋季又增加了2個類型) ,對葉、花的有關性狀如葉色、葉長寬比、花色、花瓣長寬比、小花數、花瓣數進行了聚類分析。Lacking of space locality in time domain, fourier analysis can only make certain of the integral singularity of a function or signal. as a result ; it is difficult to detect the spatial position and distribution of broken signal by fourier analysis. wavelet analysis has the characteristic of spatial locality, and its wideness in both windows of the time and the frequency can be adjusted, so it can analyze the details of a signal
小波分析優于傅里葉之處在於,小波分析在時域和頻域同時具有良好的局部化性質,因為小波函數是緊支集,而三角正、餘弦的區間是無窮區間,所以小波變換可以對高頻成分採用逐漸精細的時域或空間域取代步長,從而可以聚焦到對象的任意細節。Inside this booklet are two stamp sheetlets. each stamp sheetlet bears two stamps depicting two types of trees commonly found in hong kong. they are bauhinia blakeana ( $ 1. 30 ) and chinese banyan ( $ 2. 50 ) on one sheetlet ; and cotton tree ( $ 3. 10 ) and schima ( $ 5. 00 ) on the other
