The design plan of synthetic gauge for bisected tee-connection has been fixed through research.

This paper introduced a new method of designing of synthetic gauge for measuring the hole position, according to the condition that diameter tolerance is large and the hole position accuracy is high.

The new measurement system of thermal deformation adopts combined gauges as standard length,single switchable measuring head and inductance micrometers to carry on relative measurement.

In the pulse composite electroforming,when other process parameters were remained stationary,the effects of the ZrO_(2)concentration in electrolyte,T_(on),T_(off) and the cathode current density on ZrO_(2)content in nano-composite electroforming deposits and codeposition rate were discussed.
