Taking a view of pure time field, this paper presents dissolvable signals and basic concepts of sampling ; and also gives the very condition of discrete of signal ; this paper uses linear algebra to analysis this kind of signal and then gives some results and relevant deductions ; based on these results, 1 made a further step to analysis some typical band - limited signals in order to proof the coherence of my theory of dissolvable signal to the typical sampling theory ; i made some preliminary study about the feasibility of sampling and recovering of this kind of signal
本文從純時域角度出發，給出了可分解信號及其采樣的基本概念；也指出了信號可離散化的條件；利用線性代數理論給出了對這類信號進行采樣的分析理論及相應的推論；並用這些結論對典型的帶限信號進行了分析，證明可分解信號采樣定理與經典采樣理論的一致性；初步探討了對這類信號的實行采樣與恢復的工程實現問題。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。There are two tracks for the modern educational architecture in chengdu, one is the changdu native self - built architecture, the developing course is to inherit the traditional architecture style and improve it at first, then growing to take in and accept the advanced western educational architectural styles, the other track is that the western churches, entering chengdu from the coastline area, built schools and brought new architectural styles, the development of the religious school buildings is to absorb the native architectural signs, elements and try to combine with the native style
成都近代教育建築有兩條發展軌跡，一是國人自辦的成都本土教育的建築，它們發展軌跡是由最初對傳統建築的沿襲與改造，而後逐步發展到對于西方先進的教育建築類型的接納和吸收的過程；另一，近代西方教會勢力由沿海地區西進而來，他們興辦的學校，給成都帶來新的教育建築類型，教會學校建築的發展是逐漸吸收本地建築符號、元素，試圖與當地建築風格相融合的過程。He extinguished the candle by a sharp expiration of breath upon its flame, drew two spoonseat deal chairs to the hearthstone, one for stephen with its back to the area window, the other for himself when necessary, knelt on one knee, composed in the grate a pyre of crosslaid resintipped sticks and various coloured papers and irregular polygons of best abram coal at twentyone shillings a ton from the yard of messrs flower and m donald of 14 d olier street, kindled it at three projecting points of paper with one ignited lucifer match, thereby releasing the potential energy contained in the fuel by allowing its carbon and hydrogen elements to enter into free union with the oxygen of the air
將兩把匙形木椅拖到爐邊，一把是給斯蒂芬準備的，椅背朝著面臨院子的窗戶，一把是自己坐的。他單膝著地，往爐格子里放了些粘著樹脂的枝條和五顏六色的紙張，以及從坐落於多利埃街十四號的弗羅爾與麥唐納公司的堆置場以每噸二十一先令的代價買來的優質阿布拉莫木炭。他把這些都十字交叉地堆成不規則的多角形，劃了一根安全火柴，在紙張的三個角落點上火。The function of the software use pc - computer to dispose the output signal which is produced by the device as following steps : ( 1 ) to input data by parallel interface ( 2 ) to record and form a file ( 3 ) to demonstrate results step by step ( 4 ) the results could be compiled ( 5 ) it can synthesis in the permitted error scope, substituted original dot for line or arc, finally we could get a graph that is described by some simply curve.

利用一個新的輔助橢圓方程將求解非線性發展方程精確解的問題轉化為一個代數方程組進行求解，與已有的輔助橢圓方程法的主要不同是，應用這一新的輔助橢圓方程后降低了平衡次數，減少了所得的代數方程組的個數和方程的項數，從而大大地簡化了代數方程組的求解.同時，由於輔助橢圓方程的解中包含了更多的可選參數，從而給出了非線性發展方程的更多形式的解.作為應用，藉助于計算機的符號計算，求得了一些非線性發展方程的新的精確周期解Once you have made the payment and paid ， the western union agent will issue a unique transaction identification number known as money transfer control number ( mtcn ). this is your confirmation
