The negotiable instrument of present age is impacted by modern means of electronic payment , but only its extent of application is extruded . although its function of exchange , payment and settlement can be partly performed by modern electronic financial shifting system and the means of non - paper settlement , its intrinsic function , for instance , the function of credit and financing , shall not be replaced by other financial means . therefore , it is no reason to despise the development and improvement of negotiable instrument law and its theory 当代票据,虽然受电子化和现代支付手段的冲击,但也不过是使用范围被挤压而已,其固有的功能如信用、融资,并无其他金融形式可以替代,即使汇兑、支付、结算等功能也只是部分地由现代电子资金移转制度和无纸化的支付结算方式来完成,因此,没理由对票据法及票据理论的发展和完善表现出不应有的轻视。
The main works and results we have accomplished are as follows : 1 ) red - detuned locking of cooling / trapping laser to the cycling transition of cesium cooling has been accomplished by means of a double - passed acoustic - optical frequency shifting system and the technique of saturated absorption spectroscopy . the short - term residual frequency jitter is less than 350khz ; 2 ) automatic controlling system by computer programs has been established for laser cooling and trapping and cavity qed experiment . the laser and magnetic fields can be controlled by the acoustic - optical modulator and the electronic - controlled logic gate respectively 具体如下: 1 )采用了往返两次通过的声光频移系统结合饱和吸收光谱技术的实验方案,实现了冷却俘获激光频率相对于铯原子冷却循环跃迁的负失谐锁定,短期频率稳定度约在350khz以内,并可方便地调节其负失谐量而无须对后续光路再作调整; 2 )建立了一套基于计算机程序控制的、铯原子激光冷却与俘获实验所需的时序控制系统。
The third part concerns the managing system of gfi which consists of gfi employment and concentrated management system , combined - signing system , reporting system in fixed and non - fixed term , retreating and shifting system and checking & awarding system . chapter 3 basis of gfis gf1s have its basis on theory law and practice 在第三节中论述财务总监的管理制度,并分为以下几部分:一、财务总监聘用与集中管理制度;二、联签制度;三、财务总监的报告制度,包括定期与不定期报告:四、回避与轮换制度;五、考核与奖励制度。
