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

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

There is ahvays a temporary tradeoff befween inflation and unemploy from inflation per se, but from unanticipated inflation, which generally means, from a rising rate of inflation Milton friedman Most economists analyze short-run fluctuations in aggregate income and the price level using the model of aggregate demand and aggregate supply. In the IS-LM modek hapters, we examined aggregate demand in some detail. The IS-LM model-together with its open-economy cousin the Mundell-Fleming model-shows how changes in monetary and fiscal policy and shocks to the money and goods markets shift the aggregate demand curve. In this chapter

When conducting monetary and fiscal policy, policymakers often look be- yond their own country's borders Even if domestic prosperity is their sole ob jective, it is necessary for them to consider the rest of the world. The international flow of goods and services and the international flow of capital can affect an economy in profound ways. Policymakers ignore these effects at In this chapter we extend our analysis of aggregate demand to include inter- national trade and finance. The model developed in this chapter, called the Mundell-Fleming model, is an open-economy version of the IS-LM model. Both models stress the interaction between the goods market and the money market. Both models assume that the price level is fixed and then show what

Aggregate Demand ll Science is a parasite: the greater the patient population the better the ad ance in physiology and pathology; and out of pathology arises therapy The year 1932 was the trough of the great depression, and from its rotten soil was belatedly begot a new subject that today we call macroeconomics In Chapter 10 we assembled the pieces of the IS-LM model. We saw that the IS curve represents the equilibrium in the market for goods and services, that the LM curve represents the equilibrium in the market for real money balances, and that the IS and LM curves together
