The Similarities and Differences between the Goals of Bilingual Education in China and the United States

This paper studies the similarities and differences between the goals of bilingual education in China and the United States. China and the U. S. have similar purposes in providing bilingual education to language minorities at the elementary-secondary school level. The Americans use bilingual education as a remedy, but most Chinese treat it as a tool for tangible interests. American colleges and universities provide monolingual instruction only, but their Chinese counterparts are promoting bilingual instruction today. Many have considered American bilingual education a failure. The validity of China＇s collegiate bilingual instruction is under debating. More research work must be done before we learn how bilingual education may be efficiently and effectively provided to different groups with various educational needs.     

Experimental Study of Structure Shock Vibration in Soil Caused by Explosion of Conventional Weapons

When hitting underground structures directly or exploding in rock-soil media near underground structures, the conventional weapons with large charge weight will make underground structures be subjected to strong shock vibration and cause personal casualty and damage of precision electronic equipments. The shock vibration has become one of the cardinal killing means of weapons. However, the existing methods of predicting structure shock vibration are limited evidently. In this paper the coupling coefficient of acceleration in clayey soil is obtained firstly. Subsequently based on repeated experiments of chemical explosion, after dimension analysis and by using method of multivariate stepwise regression, the calculation formulae of shock vibration acceleration for the underground structure are obtained finally. The formulae consider top and side explosion respectively, taking into account the effects of penetration depth, charge weight, distance to explosion center, rock-soil media, size of structure and buried depth. They are easy to use with high practicability and degree of confidence, and can provide credible evidence for prediction of shock vibration and vibration isolating design of underground structure.     

期货交易与实物交割关系实证研究与交易头寸控制模型

章从交割率计算、持仓量、交易头寸集中水平与实物交割关系入手，实证检验了二的内在高度相关性，指出风险监控应以实物交割安全为中心。要确保实物交割安全，不仅要从交割环节，更应从交易环节做起。并在交易环节构建了以实物交割安全为核心的交易头寸动态控制模型。
