采用同时平衡和质量守恒原理对全液相常温常压法制备CuInSe2(CIS)粉体过程中Cu+-In3+-Se2--NH3-L2--Cl--H2O体系的热力学平衡进行分析,并绘制一系列的浓度对数lgc-pH值曲线.依据平衡图,发现溶液中[NH3]T的变化主要影响溶液中[Cu+]T在体系中的浓度变化,[L2-]T的变化主要影响的是体系中[In3+]T的浓度变化,而[Cl-]T的变化对[Cu+]T和[In3+]T的浓度变化均有影响,并可发现在pH7.0~8.5时沉淀率最高.依据Cu+-In3+-Se2--NH3-L2--Cl--H2O体系的同时平衡和质量守恒原理,采用全液相常温常压法,在pH7.0~8.5条件下制备出粒径在20~50nm且基本符合标准化学计量比的CIS纳米粉体

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

In lecture D2 we introduced the position velocity and acceleration vectors and referred them to a fixed cartesian coordinate system. While it is clear that the choice of coordinate system does not affect the final answer, we shall see that, in practical problems, the choice of a specific system may simplify the calculations considerably. In previous lectures, all the vectors at all points in the trajectory were expressed in the

What is Metamorphism?1) Metamorphism is the change in form that happens in Earths crustal rocks in response to changes in temperature and pressure

Lead-in activities What is ethics in our country? Honesty and modest are two basic ethics in our country. A society with ethics is a society with prosperity, so is business. 2. By far, which country is the relatively clear country in the world? Why? Singapore. two possible reasons: near-perfect welfare system; high salary for all the working people

When an electric charge is supported at rest in a static gravitational field, its electric field is not supported with the charge, and it falls freely in the gravitationa field. Drawing the electric field lines continuously in time, we find that they always emerge from the charge, but the electric field is curved and there is a stress force between the freely falling (curved)field and the static charge. The charge radiates
