Therefore, the grid-connected inverters play an important role in the distributed generation systems [1]–[4].
(6) The voltages ud* and uq* can be obtained from Fig. 1
Therefore, the voltages ud* and uq* cannot directly reflect the change of p* and q* from (7), (8), and Fig. 1, which causes low dynamic response.

At last, the four injection screws were evaluated based on melt viscosity homogeneity method. 1.
Gao et al [1-2] studied the melting mechanisms and the melt temperature homogeneity through visualization experiment.
In this work, the configuration and size of four screws whose diameters are all 36mm are described in Fig.1.

Introduction Micromachined gyroscope is the key research field because it is widely applied in both civil and military field [1,2].
Structure of a capacitive micromachined gyroscope Fig. 1 shows the structure of a capacitive micromachined gyroscope.
There are two movable directions as shown in Fig 1, one is the driving direction (marked as X direction in Fig 1), the other is the sensing direction (marked as Y direction).

Indeed, electrochemical etching is an efficient process to perform porous regions in SiC substrates as demonstrated for the first time by Shor and coworkers [1].
A double tank electrochemical cell was specially designed by our lab and fabricated by AMMT ® to anodize samples with diameters ranging from 1 to 15 cm.
