1 The calculation of the gyral moment is more complicated in the design of tube-shaped vessels, especially the calculation of the gyral moment of the liquid metal remained in the vessel.

2 Gyral kiln is a long tube-shape large-scale equipment, which is widely used in non-ferrous metallurgy, cement, chemical industry and so on.

3 Purpose : To analyse CT manifestations of gyral malformations of neuronal migrationl anomaly.

4 Therefore, to develop the block-wheel cylinder with reasonable structure and long service life is the important topic in the transforms of equipments in gyral kiln.

5 The sucking device has a sucking-disk structure which contains multi-sucking mouths and gyral grooves in order to minimize the deformation of the wafer.

6 Through the strength analysis of the main body, it verifies that blocking-wheel cylinder can bear impact loads by the gyral kilns.

7 For replacing the block-wheel cylinder frequently and inconveniently, it wastes of the manpower and material resource massively, and influences seriously the role of block-wheel device and gyral kiln.

8 Cortical tubers were detected in 10 cases, the patterns of cortical tubers were gyral core lesion and H-shaped lesion on MRI.

9 Leptomeningeal metastasis appear as enhancing curvilinear segments following the gyral convolutions often with small nodular deposits on the surface of the brain.

10 Materials and Methods: CT manifestations of 20 patients with gyral malformation of neuronal migrational anomaly were retrospectively reviewed.

11 Turning a way is to pass exert oneself to do sth. to same way or opposite way, make articulatory extend or a kind of gyral gimmick.
