近似估算 meaning in Chinese
approximate estimation
Examples
- I asked for a rough estimate but it was way off base .
我要的是近似估算，结果却完全搞错了。 - It was proposed that the reduction in pr ( n ) during the electric fatigue process was probably caused by the increase of a domain and anti - ferroelectric c * domain ( both leading to the increase in non - switching of c domain ) in combining with the experimental observation that the pr ( n ) values lowered with the rise of n . the equation which can be used to calculate the differences in non - switchable domain due to the increase of n was also given . variations of domain - switching with changes of n are discussed according to the in - situ xrd measurements
根据原位xrd实验观测结果，给出了c a畴的90畴变的近似估算公式，并结合宏观剩余极化强度随n增加而降低的实验观测，提出了疲劳过程中材料的剩余极化强度p _ r ( n )降低是由于a畴的增加和反铁电c ~ *畴增加导致不可翻转c畴增加共同造成的假设，并给出了不可翻转畴随n增加而变化的估算公式。 - Suggest the method of division to measure the largest compacted dry density of dam ' s material with super large diameter approximately . according to the research of predecessor , suggest applying the effective void ratio or the effective void rate to compute the coefficient of permeability approximately
采用了表面振动法进行室内最大干密度的研究，提出了比例法近似测定超径粗粒土最大干密度；在前人研究的基础上，提出采用有效孔隙率或有效孔隙比的渗透系数近似估算。 - So , it is main problem that set up mathematic model for ship motion simulation . however , the calculating definition of maneuverability motion depends on the hydrodynamic derivatives . for this reason , the purpose of this article is : apply newly hydrodynamic derivatives formula to calculate hydrodynamic forces and offer the ship maneuverability index during the design stages
因此，本文的研究目的是：运用最近提出的水动力导数近似估算公式，获得较为精确的水动力计算，为船舶工程人员在船舶初始设计阶段提供使用工具，使他们在设计时就能较准确地获得实船操纵性能指标。
