In order to determine the interactions between copper atoms and rubber molecules, this article used X-ray diffraction to analyse the cure specimen of size materials mixed with copper powder for the first time, found the atomic nucleus distances between copper and atoms in rubber molecules were equal to 0.23169nm and 0.3043nm. 0.3043nm reflected the atomic distance between Cu and S under the action of Van der Waals force. 0.23169nm stated that there was chemical interaction between Cu atoms and rubber molecules

This book is designed to help the engineer understand the principles of metal form￾ing and to analyze forming problems – both the mechanics of forming processes and how the properties of metals interact with the processes. In this book, an entire chapter is devoted to forming limit diagrams and various aspects of stamping and another to other sheet forming operations. Sheet testing is covered in a separate chapter. Coverage of sheet metal properties has been expanded. Interesting end￾of-chapter notes have been added throughout, as well as references. More than 200 end-of-chapter problems are also included

1.Describe property,plant,and equipment. 2.Identify the costs to include in initial valuation of property, plant,and equipment. 3.Describe the accounting problems associated with self- constructed assets. 4.Describe the accounting problems associated with interest capitalization. 5.Understand accounting issues related to acquiring and valuing plant assets. 6.Describe the accounting treatment for costs subsequent to acquisition. 7.Describe the accounting treatment for the disposal of property, plant,and equipment

1.Identify accounting topics where the time value of money is relevant. 2.Distinguish between simple and compound interest. 3.Use appropriate compound interest tables. 4.Identify variables fundamental to solving interest problems. 5.Solve future and present value of 1 problems. 6.Solve future value of ordinary and annuity due problems. 7.Solve present value of ordinary and annuity due problems. 8.Solve present value problems related to deferred annuities and bonds. 9.Apply expected cash flows to present value measurement

In this paper the phase diagrams of LaCl3-LiCl and CeCl3-LiCl systems have been experimentally determined and theoretically calculated. Bath are simple eutectic systems. The eutectic points are at 25mol% LaCl3, 508℃ and 27mol% CeCl3, 494℃, respectively. The optimized phase diagrams and thermodynamical data of LaCl3-LiCl and CeCl3-LiCl systems with self consistency are a better basis for constructing ternary phase diagrams

The physico-chemical behavior of rare earth elements in low sulphur 16Mn steel and their ability to enhance the corrosion resistance of the steel in sea water studied in this paper. The results indicate that Ce and La in 16Mn steel all have the abilities such as deoxidation, desulphidation, refining grains and cleaning grain boundaries and matrix etc. The anodic and cathodic polarization curves show that the rare earth elements added in 16Mn steel enhance the corrosion resistance of the steel in sea water
