- The centre of gravity is displaced by a weight below the rotational axis. 调节旋转轴之下的一个重物,使重心发生位移。
- For the Earth, the rotational axis tilts 23.5. As a result, there is no seasonal change in Venus. 地球的自转轴倾角为23.;5;所以金星并没有四季之分。
- Either of the regions contiguous to the extremities of the earth's rotational axis, the North Pole or the South Pole. 南极,北极与地球的自转轴的两端相连的地区中的任一地区,即北极或南极
- The upward angle at which the rotational axis (PAP) tilts off the horizontal upon release of a hook ball. 轴倾角-----球离手时旋转轴(PAP)相对于水平线的向上倾斜的角度
- Uanus is the only planet in our solar system with its rotational axis tilted over sideways. 天王星是我们太阳系中唯一一个轴线倾斜近乎水平的行星。
- Magnetic fields might also squeeze matter outward along the rotational axis in two polar jets. 例如,磁场或许会利用新生中子星的转动能量,多推震波一把。
- Study Design. Different geometrical and biomechanical ealuations were performed to determine the axial rotational axis of the thoracic spine. 研究设计:我们用不同的几何力学和生物力学方法来测定胸椎的旋转轴。
- Since the rotational axis of the Earth is tilted from the revolution axis by 23.5, the Sun, for example, rises at different directions at different times during the year. 由于地球的自转轴相对于公转轨道平面倾斜了23.;5度;再加上地球的绕日运动;所以太阳东升的方位角会随日子改变。
- On this day, the earth's angle to the sun was perpendicular to its rotational axis, so that the sun shines equally on the northern and southern hemispheres. 这一天,地球与太阳的角度与其旋转轴垂直,因此太阳均等地照耀着北半球和南半球。
- Having or constituting a support with two perpendicular axes, one of which is parallel to the earth's rotational axis. 赤道平面上的由两条互相垂直的轴支撑的,其中一条与地轴平行
- Having or constituting a support with two perpendicular axes,one of which is parallel to the earth's rotational axis. 赤道平面上的由两条互相垂直的轴支撑的,其中一条与地轴平行
- The goal is to find the optimum rotation axis to avoid lens barrel distortion (aka parallax error) in your shots. 我们的目标就是找到最佳的旋转轴,以避免镜头的桶状变形(也被称为视差)。
- The tripod and head's rotation axis runs through the center column of the tripod. 三脚架和云台的旋转轴穿过三脚架的中柱。
- Angles are measured clockwise when looking along the rotation axis toward the origin. 角度按照沿旋转轴向原点方向看的顺时针方向测量。
- By analyzing the scanning galvanometer the effect of offset between reflector surface and its rotate axis is given quantitatively. 通过对扫描振镜的分析,定量给出了反射镜反射面与振镜转轴偏心对扫描光线的影响。
- Material along the rotation axis falls vertically toward the equatorial plane much faster. 沿著转轴两侧分布的物质则快速笔直地落入赤道面。
- Magnetar's rotation axis of rotation around the second 60 weeks, it is super star after the explosion residues. 磁星每秒钟围绕旋转轴自转60周,它是超级大恒星发生爆炸后的残留物。
- First, we examined the problem from a geometrical point of iew then we modeled the different rotational axes by studying the change in olume of the spinal canal. 在研究过程中,我们先在几何学方面通过研究椎管容量来模拟不同的旋转轴。
- In this axial turbine, steam always flows along the axis of rotated axis, thus, all blades extend with the radiation shape along the axis outward. 在这种轴流式涡轮机中,蒸汽总是沿主轴的旋转轴流动的,因此,叶片由主轴向外呈辐射状展开。
