In order to study the flexible wing,the lift force experimental research was put up on the aerodynamic force measurement experimental platform which was designed and developed by authors.

According to the point which the insect wings are perceived as the flexible wing, the study of the bionics flapping aerocraft in.

Improvement on flexibility of water-reusing system with multi-contaminants through changing network structure;

Virtual Part-A New Concept for Increasing Productivity and Flexibility of Flexible Machines;

Studies on flexible unsaturated polyester resin from polyether glycol and its flexible curing system;

A flexible reforming of plant for the food additive sodium phosphate production;

GMAW flexible accommodation for closed round bead with torches;

It points out the importance that the traditional modular machine-tool and its production line have the flexibleness.

In the field of machine control, the conception of flexibleness and openness are very similar.

Theory and methodology of mechanism dynamical reliability analysis considered the influence of friction and flexibleness were presented.

Suppleness Technology of Workflow Management System;

It also introduces construction methods of the steel framed HDPE pipe that has a suppleness characteristic of expansion with heat and contracts with cold,this laying a foundation for the application of steel framed HDPE pipe widely used in Various fields in future.

Therefore, granting grace period must be limited on some special occasions, so that we could strengthen rigidity and weaken suppleness of law in execution procedure.
