grain motion 中文意思是什麼
grain motion
解釋
顆粒移動-
As there is lost motion in every kind of machinery, so there is lost motion in the grain market due to momentum, which drives an option slightly above or below a resistance level
每種機器都有空轉的情況，因此穀物市場當然也由於其運行在一個阻力水平上下很小的范圍內的動力而變成空轉。 -
Accordingly, a new framework, which provides a common scheme for the numerical simulation on the macroscopic behavior of ferroelectrics though multi - scale analysis on the coupled thermo - electrics - mechanical behavior of multiphase in heterogeneous material, is induced to construct the effective constitutive equation of multiphase. in chapter four, based on the law of domain nucleation and domain wall motion of 1800 domain switching, a new scheme of domain switching and numerical simulation approach is put forward on the foundation of thermodynamics. driving traction, nucleation criterion, velocity of domain wall motion, kinetic relation and rate of domain switching in a single grain are given
第四章以鐵電體1800疇變的過程中形核規律和疇界運動規律的實驗觀察結果為基礎，根據熱力學理論建立鐵電體疇變的理論框架和數值模擬方法；給出了單疇內疇變驅動力、新疇形核準則、疇界運動速度公式、疇變動力學的表達式，單晶的疇變速率公式；用細觀力學的觀點給出了對多晶鐵電體多場耦合的有效性質進行包含疇變速率影響的多尺度分析方法。 -
Ann is a adaptive and non - linear dynamic system made from superposition of many simple components which we call neuron. the question for computation of d _ ( cmax ) belongs to incipient motion of sediment in essence, which is the same question with two different sides, because computation of critical condition ( including critical velocity critical shear stress critical power ) for a grain size under a bed - load condition is equal to computation of a grain size during incipient motion under the bed - load condition and the water flow condition given before. and computation of gross bed - load transport rate has great relationship with standard of incipient motion
對于d _ （ cmax ）的推求，在本質上還是泥沙的起動問題，因為尋求某種床沙條件下某級泥沙的起動條件（如起動流速、起動切應力、起動功率）和尋求某種水流和床沙條件下的起動粒徑是同一問題的兩個方面而已；而對于推移質總輸沙率推求也和泥沙起動問題中的起動標準選擇緊密相關。 -
Computing the maximal grain size during incipient motion d _ ( cmax ) and gross bed - load transport rate in non - uniform sediment with a wide distribution are two important indexes for description its transport law, and it is also a core question for discussion in non - uniform sediment research
寬級配非均勻沙最大起動粒徑d _ （ cmax ）和推移質總輸沙率的推求是刻畫非均勻沙推移質輸移規律的兩個重要指標，也是研究非均勻沙運動規律的核心課題之一。 -
The reduced localizations can be understood by the effects that grain boundaries promote rotation of grains in shear bands, while the accommodating role of grain boundaries to deformation can be understood by restraining rotation of grains in non - shear bands. from the view of overcoming interlocking between neighboring grains, increasing grain boundaries relative thickness implied grains mutual motion more easily
結果顯示：晶界通過促進剪切帶晶粒轉動而使局部變形不均勻性降低，而通過抑制非剪切帶晶粒轉動使晶界協調變形的作用增大；從克服晶粒互鎖角度看，增大晶界相對厚度使晶粒相對運動更容易。 -
In general, polycrystal or twin magnetostrictive materials are used as the drive unit in micro - displacement actuator. however, the displacement output of the actuator under low magnetic field is small and its precision is limited, as a result of motion restriction of magnetic domain walls by grain boundaries in polycrystal or twin magnetostrictve materials
磁致伸縮是一種磁?機械耦合現象，以tb - dy - fe為代表的稀土超磁致伸縮材料，其伸縮量為普通壓電陶瓷的30 - 50倍，響應時間低於10 . 6秒，是理想的位移致動材料。 -
First, total resistance is derived by summing different resistance components. the relationship between resistance of still plane bed and energy slope has been proposed from the similarity between sediment incipient motion and still bed resistance. and this relationship can be used in computing grain resistance
一是從不同的床面阻力單元出發，利用泥沙起動與定床阻力之間的相似性研究了靜平整床面的阻力，建立了靜平整床面阻力與能坡之間的關系式，並將此式用於沙粒阻力的計算。 -
