圆心角 meaning in English
angle at center
angle at the centre
center angle
central angle
centre angle
radius angle
Examples
- Let angle aob be taken as a central angle of a circle .
设取AOB为一个圆的圆心角。 - A radian is the angle subtended by an arc of a circle whose length is just equal to the radius .
一弧度就是长度刚好等于半径的一段圆弧所对的圆心角。 - Let angle aob be taken as a central angle of a circle
设取aob为一个圆的圆心角。 - An approach of representing circular arcs with nurbs of degree two was given by others , but it was based on the hypothesis that the arc angle is less than n
李强等在已知三个型值点时，通过直接给出控制顶点和权因子的方法得到用二次nurbs精确表示圆弧的方法，但只给出圆弧的圆心角小于的情况。 - The test shows that nominal transverse splitting strength of concrete cylinder is well correlated to the concrete cube strength and splitting strength of cube and cylinder , especially , above interrelation is more ideal when hold - down central angle is 90
经试验证明，混凝土圆柱体的横劈名义强度与混凝土的抗压强度、立方体及圆柱体纵劈强度有很好的相关性，尤其当压具圆心角为90时，上述关系更为理想。
