Calculation of sinking displacement missing in measuring with common logarithm function 用常用对数函数计算罗子山水库大坝漏测沉陷量
The value Δ t of reservoir displayed by SP curves is read from top to bottom; and the dispersing or distributing points of formation depth ( H) versus its corresponding value Δ t are plotted with the depth H as abscissa and common logarithm as ordinate. 利用声波时差,结合自然电位,在储集层段自上而下读取声波时差值(Δt),并以地层深度(H)为横坐标,以对数为纵坐标,作散点图;
Using the slope-ratio technique from regression of common logarithm value of different indexes on mean daily Zn intake, relative bioavailability of Zn-Lys and Zn-Met were different. 采用斜率比法,不同判据指标得到的赖氨酸螯合锌和蛋氨酸螯合锌的相对生物学效价不同。
It has become increasingly common to implement discrete logarithm based public key protocols on elliptic curves over finite fields. 基于有限域上椭圆曲线公开密钥协议的离散对数计算算法正日益成为热点。
Proxy signature systems have great applications in e-business whose secure-ty is based on the difficulty of integer factoring or the difficulty of solving the common discrete logarithm problem. 代理签名体制在电子商务中的应用很广泛,目前的代理签名体制安全性主要是基于求解大数因子分解问题的困难性或求解离散对数问题的困难性。
