English immersion in the mainland of China has started in Xi＇an since the late 1990s, and extended into other cities in the mainland of China. This study reported the findings of the students＇ interactive peer learning model in the immersion programs, such as peer prompting and waiting; non-verbal expressions; correcting errors and modulating speaking volume; translation; attending to the peer interlocutor＇ s needs; and reciprocating peer assistance.

This article does some researches on the impact of English Immersion on children. Through the practice and observation of children in the immersion program, we find that English Immersion has the following impacts on children： 1） The English language learning is immersed into the process of thematic activities, Children in the Immersion learn English naturally, joyfully and systematically. They tend to cooperate well. 2） The language immersion is an integrated model in which children feel no cultural barriers. 3） English learning enhances the learning of Pingying, and vice versa. 4） There is little gap between genders. 5） Social and economic difference does not influence their learning. 6） English rhyming, chanting and songs arouse great interest in them. 7） Drama makes children very confident in their performance. They learn to think and settle problems through the performance. English immersion gives children cognitive development and enforces the language they are learning.

The influences of CaZrO3 on the dielectric properties and microstructures of BaTiO3 (BT)-based ceramics have been investigated. The experiment results showed that the dielectric constant at room temperature increased with the addition of CaZrO3 in the range of 0―3.0 mol%, which could be explained by the growth of BT grains. XRD analysis revealed that the tetragonality declined as CaZrO3 concentration in-creased. XRD patterns of BT ceramics with different amounts of CaZrO3 doping were analyzed by a recently developed procedure-materials analysis using diffrac-tion (MAUD), which was based on the Rietveld method combined with Fourier analysis. The results depicted that the high temperature peak of tempera-ture-capacitance characteristics (TCC) was largely dependent on the micro-strain of samples. Furthermore, more CaZrO3 doping resulted in lower porosity and higher density. It was revealed that proper usage of CaZrO3 could improve the di-electric properties significantly, which was benefit to develop X8R multi-layer ce-ramic capacitors.
