The danger and examination standard of automobile′s contamination are studied,at the same time,can promote the improvement of main measures and methods to resolve the pollution of automobile,which have important value for reducing automobile gas pollution and relieving environmental pollution attribute to automobile gas.

The anticorrosion coating designs,procedures,technical requirements,quality control system and testing standard are introduced in this paper.

This paper introduces the types and fire-resisting mechanisms of fire-proofing coatings; shows its testing standard and method; summarizes the current situation both at home and abroad of searching and applying fire-proofing coatings ,especially in several aspects of constituting dilative fire-proofing coatings: base material、deaquation reagent、 coking reagent、bubbling reagent and additives etc.

Introducing into the principle of information index,implementing the network information system management for the testing standard of the department.

Study on compaction standard of subgrade with bearing sand silt of low liquid limit;

The author analyzes the imperfection of the testing standard of the fill compaction at present,systematically summarizes the engineering properties of the filling,puts forward the compaction standard and the detection method combined with the engineering practice based on the extensive experiments and research of the various types of the soil,to accumulate the engineering experience.

By analyzing the stress distribution conditions under subgrade,the paper proposed different compaction standards of quality control.

The object of this paper is to determine the compaction criteria of loess subgrade.
