median body
解釋
半月形的中體-
First, an experimental apparatus for undulatory dorsal / median fin propulsion modes is established. based on morphological and kinematic data of the body and the dorsal / median fins of specimens, the analysis shows that the slender body is well streamlined, symmetrical
本文的實驗觀測首先建立了背鰭/背臀鰭波動推進研究的生物實驗裝置，進行仿生對象形態學和運動學觀測，提取了仿生對象的形態學和運動學特徵。 -
The sagittal planes. these are any vertical planes passing through the body parallel to the median plane. these sagittal planes divide unequally the body to right and left portions
矢狀面。與正中面平行、貫穿人體的垂直面。矢狀面將人體分為不對待的左、右兩部分。 -
Since these theoretical analyses are based on inviscid potential flow theory, theoretical calculation and computational simulation may complement each other. the hydrodynamics and undulating propulsion of specimens were studied using three dimensional computational fluid dynamics ( cfd ) modeling. the cfd analysis using kinematic model of undulatory dorsal / median fin draws a series of conclusions, which include that the body drag increases significantly with the lateral body oscillation ; the body drag is minimum while the start point of
計算結果表明游動過程中的形體阻力隨側向周期性擺動而增大;當背鰭前端位於身體側向最寬處時，形體阻力具有局部最小值，結論與實驗觀測結果相吻合;在實驗觀測的典型運動參數下，波動面的運動方程中的非對稱因素的出現使推進力增大約1 . 10倍。 -
Finally, the values of kinematic parameters in typical swimming are estimated for theoretical calculation and computational simulation. based on the kinematic formulation, this paper applies large - amplitude elongated body theory to propulsive performance of undulatory dorsal / median fins and establishes a set of equations for estimation of the propulsive force and the propeller efficiency. the calculations based on experimental data coincide with blake ’ s result in 1980
從波動運動的參數方程出發，本文基於大擺幅伸長體理論對背鰭/背臀鰭波動模式的推進性能進行了分析，推導推進力和推進效率的計算公式，利用實驗觀測典型運動參數對仿生對象的推進力和推進效率進行了理論估算，結果與blake的計算結果相吻合，從而驗證了所建運動學模型的有效性。 -
Based on bionic experiments in gymnarchus niloticus and rhinecantbus aculeatus, this paper presents a parameterized description of undulatory dorsal / median fin propulsion modes. by referring to large - amplitude elongated body theory and computational fluid dynamics simulation, this paper also provides an explanation of the external morphological and kinematic phenomena that are closely related to propulsion characteristics
本文以「尼羅河魔鬼」和「鴛鴦炮彈」為仿生實驗對象，建立背鰭/背臀鰭波動推進模式的參數化描述，對與推進性能密切相關的若干形態學及運動學特徵進行研究。 -
Medial toward the median plane of the body
內側靠近身體正中面。 -
There appears to be a small region on either side of the body ' s median plane ( which bisects the body vertically ) where people have trouble
這似乎顯示，人體正中面（將人體垂直分割成左右兩半）的兩側都有一小區死角。 -
Many descriptions are made using imaginary planes passing through the body in the anatomical position. there are median, sagittal, coronal and horizontal planes
人們根據解剖方位，設想有多個平面貫穿人體，並由此作出多種描述，即正中面、矢狀面、冠狀面和水平面。 -
To investigate whether weight reduction might be of benefit in such patients, the researchers studied 21 women with breast cancer - related arm swelling. the median body mass index ( bmi ) was 32
為研究是否減輕體重可以使這些患者獲益，研究者們對21例乳腺癌相關的上肢腫脹患者進行了研究。她們中位體重指數（ bmi ）為32 。
