Zero energy - error is used to optimize combined hybrid axisymmetric finite elements ach8 and rach8 through adjusting the combined factor
数值实验结果表明： ach8是高性能的轴对称元。
Thirdly , zero energy - error is introduced and used to optimize combined hybrid axisymmetric finite elements through adjusting the combined factor . the influence of combined factor on axisymmetric elements is discussed . finally , the main points of the whole paper are summed up and some further thoughts are put forward
数值实验结果表明：能量协调和近似能量协调的轴对称元都具有高精度、不发生poissonlocking和对网格畸变不敏感的特点；经过优化之后的轴对称元性能能够得到进一步改善。
