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。

Intensity. We will consider the strength of their holding and anti-splitting performance and modulus of elasticity.

The two phenomena have the common characteristic that they are a monotonic function of time inducing a systematic decrease of strength.

船体强度的退化是腐蚀和疲劳共同作用的结果，这两种现象具有一个共同的特征，即它们都能导致船体梁强度随时间单调退化。

The Mn alloying has less effect on environmental embrittlement. The alloy with Mn has higher ambient strength, elevated-temperature strength and larger ductility because of high cleavage strength, high movability of dislocation and high ordertype transformation temperature.

Mn的合金化对合金的环境氢脆作用影响不大，但是加Mn后的合金解理强度得到提高，位错的易动性增强，有序类型转变温度提高，故合金在宏观上表现为室温、高温强度提高、塑性增大，因此Mn的低合金化是改善Fe〓Al基有序合金力学性能的一个重要方法。

In order to solve the problem that patient's treatment time and intensity is different, we use four LED nixie light dynamic demonstration to demonstrate the treatment time, It has three pressed keys, two pressed keys are used for controlling the treatment time's addition and subtraction, one for the treatment intensity and one used for treatment meter's height level cut.

为了解决治疗强度和治疗时间的问题，我们采用了四位LED数码管动态显示治疗时间，并设置了三个按键，一个用来控制治疗强度，也就是控制激光发射头高低电平的切换，两个按键用来控制治疗时间的加减。

In the meantime, a new relation between the coefficient of variation for a normal variate and its sample size is achieved, where the probability to make mistake Ⅱ is considered 5 The probability distribution of fatigue strength at given life under large sample size determined by a new method is found to follow the log-normal distribution and normal distribution, and a new method are developed to estimate the characteristic parameters of probability distribution of fatigue strength from the probability distribution of traditional tensile properties.
