Analytic formula of the efficiency of optical-optical double-color double-resonance multi-photon ionization (OODR-MPI) is derived from the dynamic rate equation about the interaction of photon and material. Based on this formula, the influence of cha
Near space airships have gained widespread attention owing to the unique characteristics of long endurance at high altitudes; because of this characteristic, such airships have great potential for use in the fields of communication relay, early warni
Linux I/O调度层的预期调度算法AS(anticipatory scheduling)对所有的负载分配相同的预期周期，如果等待的I/O请求没有及时到达，将会带来额外的时延。针对AS算法的不足，提出了一种基于负载特性和服务时间评估改进的AS算法(WPCAS,workload characteristic and service time evluation AS)。WPCAS分为进程归类模块(PC)和服务时间评估模块(STE)两部分。PC模块根据负载特性为每类进程指定不同的预期周期。STE模
