摘要：双相不锈钢(ZG00Cr25Ni7Mo2N)海水管路使用半年后,在管路出水口靠近法兰的位置处出现裂纹。通过宏观形貌检查、微观组织分析、力学性能测试、电偶腐蚀有限元数值模拟等方法,对海水管路开裂原因进行了分析。结果表明:失效管路内部存在明显铸造缺陷,缩松、缩孔等缺陷,可以作为裂纹源引起管道开裂。管路裂纹附近组织成分与基体基本一致,均由三种相(铁素体δ、奥氏体γ、σ相)组成。裂纹对基体的相组成没有明显影响,但裂纹部位铁素体δ体积分数下降,脆性σ相增加,从而导致了材料的性能恶化,使得管路夏比冲击吸收功仅为设计标准下限的4.6%,平均断后伸长率和断面收缩率分别仅为设计标准的44%和13.2%。根据电偶腐蚀有限元数值模拟结果,失效管路的电偶腐蚀问题可能会对其裂纹扩展产生一定影响,但不是裂纹形成的主要原因。

摘要：Due to the different lighting environments or other reasons, the pixel colors may be quite different in one image which causes distinct visual discontinuities. It makes the analysis and processing of such an image more difficult and sometime impossible. In this paper, a unified multi-toning image adjustment method is proposed to solve this problem. First, a novel unsupervised clustering method was proposed to partition the source and the target image into a certain number of subsets with similar color statistics. By matching the texture characteristics and luminance distribution between the blocks, it can create optimized correspondence. Then, the color information was transferred from the matched pixels in the source blocks to the target ones. Graph cut method was used to optimize the seams between different subsets in the final step. This method can automatically perform color adjustment of a multi-toning image. It is simple and efficient. Various results show the validity of this method.

摘要：为了解决混沌加密系统密钥空间设计上的不足以及数据加密标准(DES)加密算法易被攻击的问题,将细胞神经网络与DES加密算法相结合,提出一种混合加密通信方案.该方案利用细胞神经网络产生混沌信号,将其经过取整、取模、平方、开方、增益、偏移等运算处理后,用得到的新的混沌伪随机序列将图像加密,然后利用DES算法进行再加密.文中还讨论了系统的实现方法.仿真结果表明,采用此混合加密方案进行加解密均可取得较好的效果,解密结果对细胞神经网络初值和DES密钥高度敏感,安全性能有所提高.
