.%) Sample number Powder (wt.%) Hollow balls (wt.%) Boric acid(wt.%) L0 98.5 0 1.5 L1 88.5 10 1.5 L2 78.5 20 1.5 L3 68.5 30 1.5 The density and the porosity of the CSZC samples were measured by using Archimedes method.
It is observed that the there are less pores existing among the zirconia grains with pore size of less than 10 µm in the sample without hollow balls , which is in agreement with the Fig. 1 results.

The film thickness can be controlled by variation in the number of printed layers.
Moreover, it was revealed that nano-sized grains exist on the sensing film to enhance gas sensitivity due to the increase of the surface area by inclusion of nanostructures.

However, crystal grain of silicide phases in Nb-Si composites produced by arc-melting is very coarse, which is harmful to mechanical behavior.

The explicit integration scheme is selected, rather than an implicit scheme, primarily because this is a wave propagation problem, the finite element mesh contains a large number of elements.
Finite element model Fig. 4 shows the vertical stress history at four representative locations surrounding pile P1: A1 on the pile cap, A2 on the coarse-grained fill layer, A3 on the soft clay layer and A4 below the pile tip (see Fig. 1a).

The grain was a bit became small.
When the addition of Fe was greater than 0.6%, the number and size of the impurity which included Fe became greater enough to make the bending condition worse.

Introduction Solid rocket motor (SRM) survivability depends upon the structural integrity of the grain and all bonded interfaces.
At present, large numbers of experimental study on adhesive system has been carried out [1-2].
