我們把具有哈密頓算符的體系叫做未微擾體系。We express the correspondence between the perturbed and unperturbed energies by an equation.
我們可用一個方程式表示微擾和未微擾能之間的對應關系。We construct eigenfunctions from the linear combination of the b - spline functions and the truncated fourier series, and extend pseudospectral method to calculate above - threshold ionization electron spectrum of one - dimensional atom in intense laser fields. our results are also in very good agreement with those of split - operator method
本文還利用b樣條函數和傅立葉級數的線性組合構造原子未微擾的本徵函數，將偽譜方法推廣用來計算一維模型原子在強激光場中的閾上電離譜，其結果與分裂算符方法所得的結果也符合得很好。Recently, the expression system of methylotrophic yeast has been developed quickly. as a result of its many advantages, such as high expression, high stability, high secretion and so on, many kinds of protein, including animal, plant, microorganism proteins, have been expressed by this system in the world, but we have not seen any report about yeast expression of poifn - a until now, this research is the first example in the world that poifn - a is expressed by methylotrophic yeast system
近年來，甲醇營養型酵母表達系統的研究得到迅速發展，因其具有高表達、高穩定、高分泌、能對表達的外源蛋白進行正確的折疊、加工，利於下游分離純化操作、能大規模發酵生產等諸多優點，國內外已經利用此系統表達了多種對人類有益的動植物及微生物活性蛋白，但對豬型干擾素的酵母表達還未見報導，本研究是國內外首次採用此系統表達豬型干擾素。Civil air defense alarm system was a system to dispense antiaircraft alarm sig - nal, hand hostile air attack informational communication to urbanite at wartime. it is a particular informational communication system of the civil air defense depart - ment, and can not be taken place. at the development trend of digitaliza - tion, unitization, integration of civil air defense communication, the civil air defense alarm system is developing too, for adaptation to the require of both future war and peaceful dual, and enhancing civil air defense communication system ' s directing automation. in recent years, development of different kinds of communication technology infuses new clearly energy into communication, especially spread spectrum communication, because of its strongly interference - free feature, invisibility best, realizable code division multiple access and antimultipath wane and so on merit, gets extensive use at wireless region ; the corresponding spread spectrum chips emerge as the times and get boom, which provides advantag e to realization of the circuit of spread spectrum communication. at the same time, in company with the advance of electronics level, the single chip microcomputer has a great development, world renowned chip manufacturer pushout respective products one after another, the kinds of which are too many to statiste
在人防通信的數字化、一體化、綜合化必然的發展趨勢下，人防警報系統也不斷發展，以適應未來戰爭和和平時期的雙重需要，提高人防通信系統指揮自動化。近年來，各種通信技術的發展給通信注入了活力，擴頻通信更因其抗干擾能力強、隱蔽性好、可實現碼分多址和抗多徑衰落等優點在無線領域得到了廣泛應用；其相應擴頻處理晶元應運而生並得到迅速發展，這為擴頻通信的電路實現提供便利。同時隨著微電子工藝水平的提高，單片微型計算機有了飛躍發展，世界上著名的集成電路晶元製造商紛紛推出各自的產品，單片機型號之多，已達到難以統計的地步。分享友人
