45516 实验结果表明，加权社交网络对谱的丢失具有不同的容忍性，其容忍性与网络参数之间存在密切的关系。 Experimental results show that weighted social networks have different tolerances on spectrum loss, and there is a close relationship between its tolerance and network parameters.
45517 低速率拒绝服务（LDoS, low-rate denial of service）攻击是一种新的面向 TCP 协议的攻击方式， Low-rate denial-of-service (LDoS) attack is a new type of attack mode for TCP protocol.
45518 它具有攻击速率低、隐蔽性强的特点，很难被传统 DoS 攻击检测措施发现。 Characteristics flow average rate and strong concealment make it difficult for detection by traditional DoS detecting methods.
45519 针对其特点，采用网络大数据分析技术，从路由器队列中挖掘一种 LDoS 攻击特征，将核主成分分析（KPCA, kernel principal component analysis）方法与神经网络结合，提出一种新的检测 LDoS 攻击的方法。 Accordingto characteristics of LDoS attacks, a new LDoS queue future was proposed from the router queue, the kernel principalcomponent analysis (KPCA) method was combined with neural network, and a new method was present to detect LDoS attacks.
45520 该方法将路由器队列特征采用 KPCA 降维，作为神经网络输入， The method reduced the dimensionality of queue feature via KPCA algorithm and made the reduced dimension data as the inputs of neural network.
45521 再利用 BP 神经网络自学习能力生成 LDoS 分类器，达到检测 LDoS 攻击的目的。 For the good sell-learning ability, BP neural network could generate a great LDoSattack classifier and this classifier was used to detect the attack.
45522 实验结果表明该方法有较好的检测有效性和较低的计算复杂度，对设计防御 LDoS 攻击的路由器有一些借鉴意义。 Experiment results show that the proposed approach has the characteristics of effectiveness and low algorithm complexity, which helps the design of high performance router.
45523 基于分数阶变换的图像加密方法近些年被广泛研究和使用， Fractional transform based image encryption methods have been widely studied in recent years.
45524 然而现有的基于分数阶变换的图像加密技术多在复数域进行， However,most of the existing fractional transform based image encryption methods are defined in the complex field.
45525 加密后的图像既包含了相位信息也包含了振幅信息，不利于传输和存储。 Thus, the encrypted images contain both phase and amplitude information, which is not conducive to transmission and storage.
