As one of the masterpieces, the three-act comedy, the issue of face, attacks the problem of face, a typical Chinese spirit profoundly, thus make it unique in the history of modern Chinese comedies.

Determination of Beryllium in Rice and Flour by Platform Graphite Furnace Atomic Absorption Spectrometry Using a Slurry Technique;

This paper summarized present status of safety of cereal foods in China, and pointed out the main problems of rice and flour safety.

Lack and Breakthrough of“Point”,“Line”and“Plane”;

Planar formation is to use the basic elements of dot,line and plane to satisfy the needs of design drawing according to the principle of formal art.

Comparing two kinds of framework-MCS and OSI, the characteristics of them are analyzed from four aspects, namely, layer, plane, server and communicating model.

Surface Shape of Architecture Design;

Study on point,line and surface in modern landscape architecture;

By expatiating the respective characteristics of points, lines and surfaces which are the main elements of plane composition, this paper specifically introduces the embodiment of each element in fashion design with a great number of illustrations.

Linhart was proved, which gives the upper bound of the number of faces having weight two in arrangements of halfplanes.

In this article, we give a new form of Steinberg s conjecture by showing that every plane graph without i(4≤i≤6) faces in which any two triangles have distance at least 3 is 3-colorable.

The method of integrating point and face is a scientific, effective leading method which was invented by Chinese Communists during the long-term process of theoretical research and practice.
