Optimization of HTPB-Bonding System Used for High-solid-containing PBX based on Properties of Materials Yongjiang Wei1, a,Gengguang Xu2,b, Qiuan Huang and Xuemei Liu3,c 1,2,3School of Mechatronical Engineering,Beijing Institute of Technology,Beijing,China awyj_jason@aliyun.com, balijason204@gmail.com, cshieryuexue1219@126.com Keywords: physical chemistry; high-solid content; hydroxyl-terminated polybutadiene(HTPB); bonding system; orthogonal optimization Abstract: The HTPB-bonding system used for high-solid-containing PBX was optimizied by orthogonal experiment,and three major factors that were viscosity,hardness and curing time were confirmed as mian indexes for measuring properties of bonding system.The optimal variation range for viscosity,hardness and curing time was respectively 100~125 s,20~28 HC and 4~6 days.Through fitting experimental data,the equations of these three indexes were obtained and then changing laws of that were also studied.By sovling these equations,the
Viscostiy and curing time Fig. 1 Results of orthogonal experiment 3.2.1 Viscostiy The viscosity change of bonding system with plasticizer and hardener changing was shown in Fig. 2.With the increase of plasticizer the viscosity of bonding system had a linear reduction because HTPB,plasticizer and hardener were physical blended and curing reaction nearly did not proceed.At this moment,the determinant to viscosity was the content of plasticizer and hardener.By the analysis of linear slope in Fig. 2,plasticizer 3# had the best effect to reduce viscosity and plasticizer 2# took the second place and plasticizer 3# was worst.
After the kind of plasticizer was selected and general properties of bonding system were determined,the bonding system could be designed and optimized better according to the data and formulas shown as table 3.

Research on Micro-Pool Drill and Its Drag Reduction Effect Peng Luo1, a, Shuang Yang1,b 1School of mechanical engineering, Shenyang University Of Chemical Technology, Shenyang, Liaoning, 110142, China asyhgdxlp@163.com, b236453405@qq.com Keywords: Micro-pool, Drill, Lubrication.
See specific data shown in table 1.
Fig. 7, Strain distribution of the common drill Fig. 8,Strain distribution of the micro-pool drill According to the graph and data of the finite element analysis, though the maximal stress and maximal strain of the micro-pool drill increase slightly than the common drill, they are within the scope of critical limit of breaking off.
The experimental data indicate that the micro-pool drill has certain influence on the power size, that is, influence on the friction and wearing-out during working.

This article uses large amounts of data as evidence to demonstrate the present state of the problems of great public interest, such as shortage of resources, the widening gap between the rich and the poor, employment and medical problems, with the goal of deepening people's understanding and promoting resolution of these problems.
Supported by data, this article strives to show the present state of these problems, so as to improve people’s sense of crisis and create a favorable ideological atmosphere for sustainable development.
Data show that in 2009 there were nearly 7.1 million college students who were in need of jobs, and due to the impact of the crisis, about 20 million migrant workers all over the country lost their jobs.
It is estimated that China’s economic growth rate in 2011 will slow down to 7.5%, which in turn would lead to reduction of new jobs.

Comparison with the data of the IR, the combination of carboxyl is chelating with Ti atoms.
P.A.Venz, J.T.Kloprogge and R.L.Frost studied that Elimination of carboxylic acid groups is increasingly favorable with longer chain length, but the modifying groups also become more difficult to protonate [6].Qunji Xue synthesized the 2-ethyl hexoic acid (EHA) surface-modified TiO2 nanopa- rticle use sol-gel method and studied the friction-reduction and antiwear behaviors as an oil additive in liquid paraffin [7].

Corresponding manifold learning methods[6-7] discover intrinsic low-dimensional manifold structures according to high-dimensional input data, involving Diffusion Maps[8], Multilayer Auto Encoders[9] and Maximum Variance Unfolding (MVU)[10] .
Maximum Variance Unfolding (MVU) Suppose data set is a faithful low-dimensional representation for a high-dimensional data set , each input data point is connected to its k-nearest neighbors in observation space, and G represents the corresponding neighborhood graph.

And the data should be collected to form a database for the seismic permanent deformation.
The acceleration spectrum of the Wenchuan earthquake In the section of D0+251, the deformation data is measured in four elevations.
Through the data from the two cross sections, the deformation and acceleration in the middle of the riverbed in the crest is the largest.
The data from Zipingpu dam provides a very important reference for the study of seismic permanent deformation of dam.
But the seismic deformation data are not enough to form a database for the safety evaluation.

The price fluctuation, the shortage of labor, the shrinkage of market, all contribute to the profit reduction, and to the necessity and urgency of cost control.
The scheme lays emphasis on comparison of actual result and planned aim, on the importance of percentage data in calculation, and on the reliability of the collected data.
The accuracy of the collected data is the basis on which Earned Value is applied.
Obviously the application of earned value requires some degree of data collection, done generally when more than 20% of overall project completion is achieved.[4] In such circumstances, analysis can be conducted, and prediction on budget the cost, schedule, future tendency, etc, can be made, according to the actual data collected with project in completion.
Earned Value enables the managers to have a clearer knowledge about the process of cost and schedule in completion, and to make a considered judgment on actual project implementation, according to the data collected.
