设N_A为阿伏加德罗常数的值，下列说法正确的是

A．常温常压下，46gNO₂和N₂O₄混合气体中含有的分子数为N_A

B．标况下，2.24L的H₂O所含氢原子数大于0.2N_A

C．常温下1L0.1 mol/L醋酸溶液中，水电离的氢离子数为10^—13N_A

MIMD systems can be classified into (150) -oriented systems, high-availability systems and response-oriented systems.
The goal of (150) -oriented multiprocessing is to obtain high (150) (151) minimal computing cost. The techniques employed by multiprocessor operating systems to achieve this goal take advantage of an inherent processing versus input/output balance in the workload to produce (152) and (153) . loading of system (154)

A．resource

B．resources

C．source

D．sources
