Sign s means the number of components.
In the strong acceleration field region (C), large, long crystals oriented in the direction of the acceleration field whose crystal grains are several mm long and several hundreds of µm wide can be Fig. 4.
If we can increase the sample temperature by several 100s degrees, the number of covered materials will extremely increase, and the unforeseen phenomena is expected to be found.

For example, a majority of the ethnic minority cannot be self-sufficient in grain, and onlyrely on redeployment of food from developed areas could theymaintain basic living needs;level of industrial development is relatively low, in particularthe base of light industry is weak, the self-sufficient level of mostbasic means of production and consumer goods is very low, which needs to rely on external input; the products produced by ethnic minority is focused on primary resource-oriented products whose marketsare focused on the developed regions, even though the price is distorted and under the transaction structure of “double loss of value”, this kind of unequal inter-regional trade still happens. 3.2 Analysis to the development features of highway transportation hub in ethnic minority areas The development of highway transportation suffers constraints of economic and social development, and the economic development features of ethnic minority areasdetermine the development features of

There are a number of reasons for such a situation.
Conclusions A growing number of networked embedded systems in service, which take critical control functions, require that security and safety problems [12] should be treated with special attention.

Microstructure of the cooled samples consists of pearlite (the darkest phase), bainite (grey phase mainly near the borders of grains) and the bright ferrite.
Using this brand new technology, the ATOS Triple Scan produces a high accuracy and improved measurement of shiny surface, complete data on complex components with deep pockets or fine edges such as turbine blades, reducing the number of individual scans and resulting in a simple handling.

When it reaches its limit value, as to maintain the state of equilibrium, component's load unceasingly drops and the deformation rapidly increases, and the GFRP tube presents white grain along the fiber direction.
