The signal we named it fundamental wave ; according to the fundamental wave, coefficients of the fundamental wave can be lined in a sequence. when the unique of the dissolve of the fundamental wave can be confirmed, the sequence of the coefficients can be regarded as one of representation forms of the signal itself ; theory of dissolvable signal shows that when order of the matrix of fundamental wave sampling equals to number of fundamental waves, the sequence of the sampling values from sampling points must be matched one by one with the sequence of the coefficients of fundamental waves. the sampling composed by sequences of the sampling values must be full sampling ; the relevant deductions of the theory of dissolvable signal shows that when sampling the signal, sampling frequency must be lager than the ratio of the number of fundamental waves to the occupation time of the fundamental waves ; to band - limited signals, when the fundamental wave is a sine signal, the results from the relevant deductions of theory of dissolvable signal is coherent to the classic sampling theory
本文通過分析認為,當信號集中的任一信號可表示為一系列已知信號的線性代數和時,信號集
便構成可分解信號集,已知信號稱為基波信號;對可分解信號而言,基波系數構成一序列,當對指定的基波信號集分解唯一確定時,系數序列本身
便是信號的一個表示;可分解信號采樣定理指出當基波樣值矩陣的秩等於基波數時,則由采樣點處的采樣樣構成的樣值序列必與基波系數序列一一對應,從而由該樣值序列構成的采樣必為完全采樣;可分解信號采樣定理中的推論指出,對信號集進行采樣,采樣
頻率必須大於其信號分解的基波數與其對應時長之比;對有限帶寬信號,若基波信號為正弦信號時,由可分解信號采樣定理推論給出的結論與經典采樣定理一致。

也稱倒相式開孔箱,系在音箱面板上開有倒相孔槽的一類音箱。由於開有孔,箱內的聲音
便可以輻射到外面來。倒相式音箱比密閉式音箱的低
頻延伸要好些,但低音往往不那麼結實緊湊。

Common symptoms include abdominal swelling and discomfort, frequency of micturition, changes in bowel habits, changes in menstrual pattern and postmenopausal bleeding

The modulation of sound properties over a wide range of time scales is one of the most obvious characters of oscine passerine ' s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. in oscine passerine, ipsilateral projections of ra to nxiits innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality. as a result, the songs sound well
鳴禽鳴囀的最大特點之一
便是其單次鳴唱時間長,鳴唱所包含的音節數量和音節種類繁多,因而由這些音節所組成的句型結構也是復雜多樣富於變化,且由於nxiits嚴格的側別控制(每一側核團只支配同側鳴肌) ,使其具有更強的控聲能力,其鳴聲音調變化幅度大,
頻率高,品質因數大,音色好,因而其鳴聲也悅耳動聽。
