It is well known that the construction of plate bending element is essentially more difficult than that of plane elasticity for the reason that the former has to meet the requirement of C1 continuity.

• 在板弯曲单元方面，不可否认的是板单元与平面弹性单元这两个研究领域的发展并不均衡，这一现状是与平面弹性和板弯曲的相似性理论不相协调的，因为该相似性理论表明平面弹性和板弯曲这两个理论体系是同构的。
