The humanoid countenance technology played an extraordinary important role on the realization of emotional communication between humanoid robot and human.

Design and development on human head imitation portrait robotic system with vision and facial expression;

Methods: Different facial expression video slices of happiness, sadness, surprising, fear, anger, disgust at three levels of intensity and neutral (including non-emotional and chewing) were recorded.

Teachers may use some facial expressions,gestures and body movement to make their teaching more acceptable and more understandable.

However, with the limitation of students’ vocabulary, teachers have to simplify their teaching language with the help of facial expressions and body movements, In this article, the possibility and the effect of using body language in listening, speaking, reading and writing will be further discussed.

However, in actual person-to-person interactions people usually neglect the communicative functions of facial expressions and their differences between cultures, and consequently fail to communicate efficiently.

The main measures for remanufacturing include:(1) to repair the worn,flawed parts with surface engineering technologies to recover the mechanical precision; (2) to improve the kinematic accuracy with ball screw,new drives and motors; (3) to replace the original.

In plasma electrolytic process,there are various physical and chemical effects that were used to develop various new modern surface engineering.

By using high-tech surface engineering techniques,about 62% waste parts in old engines could be repaired,and the quality of remanufactured engines became superior to the original products.

A concept of surface and surface techniques are described.

Researches on the Application of Hydrogen Peroxide to Surface Technology;

Application of surface technology in semiconductor refrigerating units;

The futrue tendency of titanium surface technology will be low cost, simple operation and high quality.
