Along with the password attack method unceasing renewal,the computation ability unceasing enhancement as well as to theoperating speed request, the tradition disperses row algorithm MD5,SHA has demonstrated their shortcoming and the insufficiency day byday, and thestructure of hash function is mostly based on block cipheralgorithm DES, but the HASH function security is established above the grouping function security,because the DES operand is very big, the operating speed veryslowly by and its itself some characteristics, thereforedisperses a row function based on the DES algorithm to havepotential unsecurity.

摘要随着密码攻击手段的不断更新、计算能力的不断提高以及对运算速度的要求，传统的散列算法MD5，SHA已日益显示出它们的缺点和不足，并且过去hash函数的构造多是基于分组密码算法DES的，而hash函数的安全性是建立在分组函数的安全性之上的，由于DES运算量很大、运算速度很慢以及其本身的一些特性，因此基于DES算法的散列函数具有潜在的不安全性。

Objective:To explore the relationship of negative schizophrenic cognitive function improvement with HVA and 5-HIAA, Method:Thirteen negative schizophrenic patients were treated with clozapine for 8 weeks,Memory,attention,executive function were assessed separately with Waise memory scale,cancellation test and Wisconsin card sorting test before and after treatment,and cerebrospinal fluid HVA and 5-HIAA levels were determined with HPLC-ECD, Results:Part of short memory was improving with decreasing of HVA or increasing of 5-HIAA,while significant correlation were not found between improvement of memory quotient,attention,executive function and change of HVA,5-HIAA, Conclusion:The great part of negative schizophrenic cognitive function improvement has marked correlation with change of DA and 5-HT

目的：探讨阴性精神分裂症认知功能的改善与HVA和5-HIAA变化的关系。方法：对13例阴性精神分裂症在氯氮平治疗前和治疗8周后分别采用韦氏成人记忆量表，数字划消测验和威斯康星卡片分类测验(Wisconsin card sorting test，WCST)评估其记忆、注意及执行功能，采用高效液相色谱-电化学检测测定其治疗前和治疗后脑脊液中DA代谢产物高香草酸和5-HT代谢产物五羟吲哚乙酸(5-HIAA)的浓度。结果：部分短时记忆随HVA降低或5-HIAA的增高而改善。而总的记忆商数，注意及执行功能的改善与HVA和5-HIAA的变化无明显相关。结论：大部分阴性精神分裂症认知功能的改善与DA和5-HT浓度变化无明显相关。

Based on the above-mentioned parameter, according to the relationship between robust estimation and nonlinear diffusion, the Turkey loss function is introduced as the diffusion function in SAR image decomposition because of its better performance, and the contour of an image is extracted by the Turkey diffusion function with the proposed diffusion parameter mentioned above.
