The composite can be a promising scaffold material for tissue engineering. 1 Introduction One of the key technologies in tissue engineering is the preparation of scaffold material for cell culture and tissue repair.
Hydroxyapaite (HA) ceramics have been used as tissue engineering material because of its good biocompatibility and osteoconductivity[7,8].
In this study, we prepared highly porous three-dimensional sponges composed of HA and ALG by the freeze-extraction and freeze-gelation methods [14]. 2 Materials and methods 2.1 Preparation of porous composite.

Extending the field of application of the drill string equipment to its use under pressure requires the use of some material brands capable to meet the requirements [2].
Depending on the temperature of heat-treatment, the hardened alloy exhibits a pearlitic to martensitic structure that results in a tough, erosion-resistant material.
But the thermal conductivity of this system is much higher than the thermal conductivity of the oil (because the polymer is water-based), and due to this the authors obtain a greater hardenability of the material and higher mechanical properties.

Therefore, in order to reduce the bending deformation and improve the measurement precision, some methods were put forward as follows: (1) The original material of transmission set, which loads radial measurement device and axial grating measuring device head, were changed, using LY12 instead of Q235-A, and the self-weight of the ontology could be reduced to the third of original; (2) In the cases of unaffected measurements, transmission set would be got rid of parts appropriately.
