So, the material with high anti-fracture properties, for enduring high impact, is desired for fabrication of microaccelerometer.
Metal material has much higher fracture toughness than silicon material, the static fracture toughness of Ni structure fabricated using UV-LIGA technology is 52.73Mpa·m1/2[6], but the static fracture toughness of polysilicon is 2 Mpa·m1/2, the minimum value of dynamic fracture toughness is 70% of the static fracture toughness.

Fig.1 showed that the degradation rate of CH2Cl2, when the light was turned on after the CdS/TiO2/ACFs materials were saturated, was significantly higher and could maintain a longer time than that one of direct light.
Before turning on light, the materials were fully saturated without the presence of the light-induced thermal desorption, then the light was turned on, the adsorbed and enriched CH2Cl2 was effectively degradated from the materials, so the adsorption equilibrium was broken, the CH2Cl2 in the airflow was continuously adsorbed.
However, at the case of direct light, the materials firstly adsorbed the CH2Cl2 from the airflow at the initial phase, then the adsorbed CH2Cl2 was photodegradated under illumination.

Materials and Methods
The studies were carried out under laboratory conditions with the use of amber from amber-bearing deposits of Rivne-Volyn Area (Ukraine).
Experimental methods in laboratory conditions are the most efficient, such as mining and laboratory investigations and modelling on equivalent materials [21, 22].

Initially 109 different material properties were used to
define the whole helicopter model including layers of composite material for the cabin floor.
Updating parameters may be material properties of substructures or groups of elements.
Then the material properties cards of these sections were given separate material property cards (PSHELL's) so that their natural frequency sensitivities to thickness changes could be studied using Solution 200 in MSC-NASTRAN.
