At present, submarine seismic records are discovered in the Shiwangzhuang Formation of the Sinian, in the Liguan Fm of the Lower Cambrian and in the Majiagou Fm of the Middle Ordovician [5-8].According to the seismic investigation materials of the west in Shandong Province, the authors studied the categories of the ancient submarine seismic records in the middle part of the Tancheng-Lujiang seismic fault zone and it’s vicinity of the Sinian, the Cambrian and Ordovician.
To make the past serve the present, this provides intuitive detailed materials for understanding the earthquakes’ destructive effect to the submarine rock and soil layers.

Experimental Starting materials and specimen preparation.
The Al2TiO5-Si3N4 composite specimens were prepared by using the above premixted powder, α-Si3N4 powder as starting materials according to the formula table 1.
First the starting materials were thoroughly mixed with addition of 6 % PVA as binder, aged for 10h and then compacted hydraulically under 2.5t into specimens of 53 mm×10 mm×10 mm.
This is because the rise in firing temperature improves the densification behavior of the materials, closer binding between the crystalline grains.

Ceramic borides, such as hafnium diboride and zirconium diboride, are members of a family of materials with extremely high melting temperatures which have been referred to as UHTCs.
UHTCs constitute a class of promising materials for use in high temperature applications, such as sharp leading edges on future generations of reentry vehicles, because of their high melting points and relatively good oxidation resistance in reentry environments [3].
The carbon fiber, silicon carbide and zirconium boride were combined each other in Cf/SiC-ZrB2 composite materials.
As can be seen from the figure, different materials have different temperature specific heat capacity.
