查询词典 eccentricity

Research indicates that each kind of shape feature such as solidity, eccentricity and area has different values and can be used as the separating parameters by comparing each feature respectively for the four ingredients, which are the seed, the fruit coat closing, the peduncle and the seedcase.

通过分别比较椒籽、闭眼、果穗梗和果皮的凹性率、椭圆度、面积值，发现四种成分的同一形态特征有一定差异，可作分离参数。

For example, the eccentricity changes over time cycles of about 100,000 and 400,000 years, with the value ranging from less than 0.01 up to 0.05.[15][16] This is equivalent to a change of the semiminor axis of the planet's orbit from 99.95% of the semimajor axis to 99.88%, respectively.

例如，离心率大约在小于0.01至0.05之间变动，变动周期大约是10万年至40万年，这相当于行星运行轨道的短半轴相对于长半轴的比例在99.55%与99.88%之间发生变动。

Several models are advanced in this dissertation, such as precision model with Kepler orbit and approximate models with conditions in the proper order of small orbital noncoplanarity, small eccentricity, short distance, short running time and equal orbital semimajor axis.

采用逐步递进的方式，推导了一系列对应Kepler轨道的精确表达式和对应小轨道非共面度、小轨道偏心率、近距离、短时间、相等的轨道半长轴等条件的近似表达式，以适合各种情形下对航天器相对轨道运动的描述。

消化和吸收了本钢冷轧厂引进的1676mm四辊冷连轧机的部分关键技术，对整个液压辊缝控制系统建立了结构模型并主要对偏心补偿进行了分析。

The experiments and simulations are performed by using a conical lens whose radius is 15 mm and basic angle is 1°. The experimental results are compared with the theoretical analysis and computer simulation results. The comparison indicates that the influence of eccentricity on the diffraction mode decreases as the radius of curvature of incidental spherical wave and the propagation distance decrease.

使用半径为15mm，底角为1°的圆锥透镜进行计算机仿真和实验，最后将实验结果与理论分析和仿真结果相比较，证明球面波的曲率半径和出射光束的传输距离越小，偏轴对衍射模式的影响越小。
