The Research on Application of New Technique in Road Quality Detection Yan Xiao Hunan Communication Polytechnic, Changsha, 410004,China room 204, No.43 building, Jinfan community, Kaifu District,Changsha, Hunan province, China Keywords:Transient vibration signals;Highway engineering;Subgrade;Degree of compaction;Detection Abstract:In order to be able to maintain the safety ,stabilize the operation, and prolong the service life of highway engineering, it is necessary to place particular emphasis on the detection of highway engineering.
On this basis, study on the corresponding relation between wave velocity and density can also realize the detection of roadbed compaction degree in the highway engineering process, therefore, the transient vibration signal is measured with outstanding value in highway engineering.
III.The Key Point of Implementation of Transient Vibration Signal in Highway Engineering Detection Transient vibration signal can be applied to detection of highway engineering, the main application link of which includes: 1.The detection of highway pavement engineering; 2.The detection of roadbed compaction degree in highway engineering.
According to the above method, staff can make a final judgement and assess the structure stability of the road through the reflected result in the time domain waveform of the vibration image when testing road pavement. 3.2 The application of transient vibration signals in highway engineering pavement compaction detection In the process of the roadbed compaction degree detection of highway engineering, the main method taken is: through the roadbed material in indoor environment, the dry density mxa values corresponding to the subgrade material are obtained in this process.
In this process, due to the moisture content of subgrade materials will have a decisive influence on longitudinal wave velocity, but the influence on Rayleigh wave velocity is relatively slighter.

Modeling and Development of Gap Adjustment Automatically Technology for Offset Machine GAO Zhenqinga, WANG Yiming and BAI Jianjun College of Information and Mechanical Engineering Beijing Institute of Graphic Communication Beijing, China aemail: gaozhenqing@bigc.edu.cn Keywords:Offset Machine; Key Parts; Gap; Adjustment automatically.
Introduction As the complexity of the offset printing and the particularity of the prints and printed materials, the process of printing depends on plenty of adjusting devices which adjust the key parts for the machine run normally.
In most cases, the manual mechanical structure are used in the adjustment process for key parts, precision and efficiency are lower.
Studied object in this research is cylinders of offset machine,the principle of other key parts is same.
(2) Parameter output: output the gap state of the key parts

Introduction Scaffolds for tissue engineering are the key to repair the defect of human tissues and organs.
According to the theory of interaction between cells and materials, wherein the adhesion of cells and material is a base [4], the suitable adhesion must occur before the migration, differentiation and proliferation [5].
The GE/CA-PCL scaffold is an ideal scaffold used for bone tissue engineering.
