CRC码硬件设计研究

A new species of genus aphaenogaster mayr from China (hymenoptera: formicidae)

ＣＲＣ码是一种具有很强检错、纠错能力的校验码，常用于计算机系统对辅存读写的校验，在通讯和计算机网络中也有广泛应用．因此，关于相对独立的ＣＲＣ码生成硬件设计研究，具有重要的现实意义．本文分析这种设计的原理，给出原理图．

A new species of Aphaenogaster Mayr was described from Lichuan city, Hubei province. The type specimens are deposited in the Institute of Zoology, Shaanxi Normal University. Aphaenogaster incurviclypea sp.nov.(figs:a,b). The new species is similar to A.beccarii (Emery), but differs from the latter as following: anterior margin of clypeus with a median notch; gaster, antenna and leg are brownish yellow; head with shagreened sculpture, and alitrunk with deep striate. Holotype:worker, Lichuan city, Hubei province, 1993-05-13,Wang Wei. Paratypes:15 workers, same as the holotype.
