高强度的

In this study, although the quantity of the scatter power can not reflect the content of blood flow, the scattered power variance is statistically significant between benignancy and malignancy （p=0.014 , sensitivity=80%, specificity 64%）. However, the PW Var does not have sufficient statistical significance in differentiate the normal tissue perfusion from the malignant one.

另外 Power Doppler的功率强度在整个实验的比较结果，虽然并不能证明与血流量、压力波有直接的关连，但是恶性肿瘤的功率强度的变异量均明显高於良性肿瘤（P=0.014 Sensitivity=80% Specificity 64%），不过恶性肿瘤却与正常组织无法区分。

目前国内许多油田已进入开发后期，开采强度不断增大，井下情况更加复杂，对于石油工程中的固井和挤堵作业涉及的封固界面的抗冲蚀破坏性能要求越来越高，迫切需要解决影响界面胶结质量的各种问题，特别是流体渗流条件下的界面胶结强度的建立和保持问题。

It was shown that 1%Eu-PZT films have the highest Rayleigh constant, which indicates the minimal interaction of defect-domain walls and high contributions to dielectric and polarization. The high mobility of domain walls, combined with the obvious improved crystallization of 1%Eu-PZT results in the increase of dielectric constant and remanent polarization.

结果表明，1％Eu-PZT薄膜的瑞利系数最大，缺陷与畴壁之间的相互作用最小，畴壁运动对介电常数和极化强度的贡献最大，加之薄膜明显改善的结晶特性，使1％Eu-PZT呈现较高的介电常数和剩余极化强度。

Because the genetic algorithms could search the optimization of objective function randomly, which via the evolution of groups, our work is based on the embedding/detecting way of "DWT-Based Audio Watermarking Using Support Vector Regression and Subsampling". And this method provides a preliminary discussion on the application of GA, which searching the individual with the highest fitness of attack-resistance in the aggregate of the optimal embedding strength. As an optimization solution of obtaining the optimal embedding strength, it could achieve an adaptive policy, and find a reasonable balance between the robustness and inaudibility of the watermark, just for the better robustness and inaudibility in the algorithm.

遗传算法是通过群体进化来随机搜索目标函数的最优化问题，对于前述基于支持向量回归机的小波域数字音频盲水印算法，进一步地探讨采用遗传算在嵌入强度集合中搜索对抗攻击能力适应度较高的个体，从而得到最佳嵌入强度的一个优化方案，以实现自适应策略，也使本算法能在水印的鲁棒性和不可感知性之间寻找到合理的平衡点，从而具有更良好透明性和鲁棒性。

Because the implanted hash function of HMAC is implemented as an individual function block, this block could be replaced easily according to the security request. The high capability of withstanding attacks of HMAC-ECDSA algorithm is proved by using modular arithmetic.

从密码学理论分析，HMAC可以使用密钥且HMAC算法的验证只在当时有效；在程序设计中实现HMAC时，可以将嵌入的哈希算法作为一个独立的模块，根据安全强度的需求替换哈希算法模块；在对攻击高抵抗性的证明中，利用模运算对HMAC-ECDSA算法的安全强度进行了验证。
