查询词典 equivalence problem

Based on the principle of energy equivalence, the expanding expression of seismic acceleration process is achieved. The seismic process is expanded into a linear combination of deterministic functions modulated by 10 uncorrelated random variables.

为此，提出了从地震动位移过程的正交展开出发，引入一类能量等效原理，获得了地震动加速度随机过程的正交展开式，进而将地震动随机过程展开为由10个独立随机变量所调制的确定性函数的线性组合形式。

Based on a hypothesis of function-equivalence which occurred not only in the mental folding but also object folding for individuals, this research indicated that individuals will search a fixed undersurface to fold up adjacent surfaces. Therefore, the type of unfold cube which had less undersurfaces and more adjacent surfaces could be more quickly for individuals to identify its undersurface, complete the mental folding and have better performance.

研究者以个体心像摺合时会与实物摺合存在功能相等性的假设，认为个体在心像摺合时会先寻找一个固定底面，再一起摺合所有邻面，因此底面数较少、邻面数较多的展开图类型会较快判定底面并完成心像摺合，而有较佳的表现。

The equivalence, performance bounds, existence, uniqueness and necessary condition of ME control are studied to show the ME method to be reasonable, applicable and effective.

ME方法是一种全局分析法，它不仅包含了MSE和MAP准则，且由于全文在整个推导中并未假定高斯性、线性和非时变等，因而原则上适用于诸如非高斯、非线性、时变等传统方法难以处理的复杂系统；不仅适用于工程系统，将其推广到决策、社会、经济等领域会更为自然和切合实际。
