High-temperature tension and creep test were conducted using single crystalline materials.
The results obtained are promising for the development of a new-type of high-temperature structural materials.
Except for the absence of grain boundaries, the microstructure observed in the single crystalline material was basically the same as those characterized in the cast and hot-forged materials in the previous study (Fig. 1)[5].

Introduction Inertial confinement fusion, often referred to as ICF, is means of producing energy by imploding small hollow micro-spheres containing thermonuclear fusion fuel [1].The goal of ICF research is to simulate the controlled laboratory implosion of fusible material to a condition of ignition and burn.
Equipments to assemble targets, the material and fabrication process of the targets have been researched interiorly at present [3-5], but research about measuring position of parts of targets during assembling and research about measuring location errors of capsules after assembling have not been reported.

Mechanical products have no real gene, but it owns the similar genetic information, such as the geometry, assembly information among parts as well as the product appearance, materials, manufacture etc, all of these are the truly genetic information of products [4].

It is necessary to rely on interactive science of man-machine interface design.
Obviously, the development of product human-machine interaction has turned the users’ needs from material needs to experience needs.
With the continuous development of science and technology, artificial intelligence (AI) is developing rapidly in the field of product design.
With the continuous development of computer technology and non-material theory, the product human-machine interaction theory is beginning to lag behind the soft interface human-machine interaction.
