In this paper, we first give an example that the bilateral weighted shift operator in c_0space is hypercyclic operator and first solve the existence problem of hypercyclic operator in c_0or c_0(Z space . And then we investigate the property of weighted shift operator in c_0 space and an important property of the hypercyclic vector of weighted shift operator in c_0 space and c_0 space. At last we give the concept of weak hypercyclic operator and weak hypercyclic vector , and give the equivalence between the weak hypercyclicity and the hypercyclicity in l~1 space.

Subsequently, through the dynamic mechanisms of investment, the endogenesis of price, consideration of the resource constraints and the alternativity between productive factors, this paper completed the historic simulation to update key data, then built the closure criteria for baseline simulation, combined the dynamic recursive methord, finally assessed the long-term impact for member states in terms of policy changes under 4 scenarios. Different to the analysis from perspective of comparative static, the assessment of long-term economic impact was started from the macroeconomic point of view and import and export trade to reflect the relationship between short-term influence and long-term impact under 4 kinds of possible policy changes.

modulation is the transmission of information to be loaded onto a high-frequency signal in the process.amplitude modulation using signal to control the rate of carrier,with its linear modulation signal changes,and maintain the same carrier frequency.in the amplitude modulation,in accordance with the strength of signals in the spectrum of different components,it is divided into ordinary am (amplitude modulation standard am),with inhibition of bilateral carrier am,the carrier single sideband suppression am.the main difference is the different methods and structure of the spectrum.

摘 要：调制是将要传送的信息装载到某一高频信号上去的过程。振幅调制是用调制信号去控制载波的幅度，使其随调制信号线性变化，而保持载波的频率不变。在幅度调制中，根据已调信号的频谱分量不同，分为普通调幅、抑制载波的双边带调幅、抑制载波的单边带调幅。它们的主要区别是产生的方法和频谱结构不同。

Traditional views of international law maintain the essentially bilateralist view set forth in the late Eighteenth Century by de Vattel's Le Droit des Gens ou Principes de la Loi Naturelle: states, as sovereigns, are bound and limited in their actions only by those rules to which they themselves have agreed to be bound and limited (explicitly in the case of treaties, explicitly or implicitly with regard to customary law).

国际法的传统观点仍停留在十八世纪末瓦特尔在 Le Droit des Gens ou Principes de la Loi Naturelle 中所提出的本质上为双边主义的观点，即主权国家的行动只会受那些它们已然同意的规则的束缚与限制（明确的形式是条约，至于习惯法则有明确或不明确之分）。

It is reassuring that many intermational broadcasters have taken the opportunity to re-equip with high-power broadcast transmitters that are not only capable of high efficiency PDM operation, but are also capable of providing conventional DSB operation, compatible AM and full SSB, in the next five years, many more will have re-equipped in preparation for SSB broadcasting.
