摘　　要：针对DNA特征比对过程中,产生的生物DNA特征图谱特征较为复杂,生物特征极为琐碎,海量生物DNA特征的对比,依然是一项十分复杂的工作。传统算法多是基于单个DAN特征进行车轮式对比。一旦生物特征过于繁琐,造成比对匹配耗时,效率较低。本文提出了一种基于云计算的生物DNA特征海量数据对比技术。建立云计算网络模型,计算生物DNA泳道特征系数,将DNA限制性片断形成的谱带从背景中分离出来,完成海量DNA数据对比。实验证明,这种算法能够避免由于DNA图谱数量过大造成的匹配耗时缺点,提高了生物DNA指纹图谱大范围比对的效率。According to characteristics of DNA than process, produce the biological characteristics of DNA spectroscopic characteristics is relatively complex, biological characteristics extremely trivial, mass personnel DNA features contrast, still is a very complicated work. More than traditional algorithm is based on a single DAN characteristics of the contrast. Once the biological features too trival, cause than matching, time-consuming, and low efficiency. Put forward based on the biological characteristics of cloud computing DNA mass data contrast technology. Establish cloud computing network model, the calculation of biological characteristics of DNA lane coefficient, DNA fragments of the form will be restricted spectrum from the background with isolated, complete mass DNA data contrast. Experiments show that the algorithm can avoid the DNA fingerprint caused by the excessive number of matching time-consuming faults, improve the biological DNA fingerprint big range than efficiency
