G w multiple point junctions provide an extremely compact , versatile solution for loop , tap , grounding , testing or sectionalizing applications through 35kv requiring multiple connection points for 200a or 600a elbows 性能稳定质量可靠美化环境,是g w产品的特点. g w电缆分支箱按照额定电流一般可以分为600a主回路和200a分支回路两种。
2 . with the method of multiple point regression , a general formula was established to estimate the annual precipitation at different elevation . rr = 1056 . 9 + luhzr in the equation : r x is the increasing rate of annual precipitation , and unit is mm / m 根据多点回归建立起估算区境任一海拔高度年降水量的通式: rz = 1056 . 9 + r hz r式中: r为需要计算点年降水量的垂直递增率,单位为mm / m 。
Obtain the conclusion that em algorithm is better than direct algorithm . aimed at measuring the large - scale network , we analyze multicast - based loss inference used multiple points and introduce minimum variance weighted average and em algorithms , and compare the difference on accuracy and 以测量大规模网络为目的,本文研究了多点多播测量技术,给出了多点多播的加权平均值算法和em算法,并比较了多点和单点在时间复杂性和估计值精度上的异同。
Based on certification and authentication software development for integration of electronic commerce , with guidance from the multiple methodologies of object - oriented programming , aspect - oriented programming and component - oriented programming together , this paper discussed the security resolution in set authentication from multiple point with j2ee framework and spring framework , then , multiple - level optimizations were operated on its software architecture 本文以集成电子商务系统的ca认证软件开发为背景,结合j2ee和spring等开发框架,以面向对象/面向方面/面向构件的多方法论为指导,从多个角度探讨了set认证安全问题的解决方案,并对其软件架构进行多级优化。
Using the index theory of fixed points for a - proper semilinear operators , we study the existence of positive solutions for the multiple point boundary value problems at rersonance . the existence theorems of positive solutions for three - point boundary value problems at rersonance for a kind of nonlinear second - order differential equation are obtained . 3 利用a - proper半线性算子不动点指标理论,我们研究了多点共振边值问题正解的存在性,得到了一类二阶非线性微分方程三点共振边值问题正解存在性定理。
