Study on Development Law of Complex Fluvial Reservoir under Water

The Bozhong oilfield (Hereinafter referred to as BZ oilfield) is a typical representative of complex fluvial reservoirs in the Bohai Sea, located in the southern Bohai Sea, with an average porosity of 30.3% and an average permeability of 643 × 10-3 μm2, belonging to medium high porosity and permeability reservoir, the reservoir has good connectivity, and the average underground crude oil viscosity is 5 mPa·s. There are many plane fault blocks, and the longitudinal oil well section is long, so the oil-water relationship is very complex. With the further development of the oilfield, the vertical and horizontal oil-water movement law, residual oil distribution and potential are unclear, resulting in rapid bottom water coning, unbalanced injection and production in the oilfield, and increasingly prominent contradictions among layers, planes and layers in the oilfield. Through numerical simulation analysis and comparison of displacement law and recovery degree under different influence conditions, this paper studies the development effect of actual sand body under different influence conditions such as different well types, different development methods and well layout positions, and takes appropriate development methods for the oilfield, which is of great significance to improve the development effect of the oilfield.

Research on the Application of Juvenile Psychological Development and Sports Acquisition Law System in Physical Education Teaching

Adolescents’physical and mental development has obvious age-stage characteristics.Therefore,before the implementation of physical education teaching,it is necessary to fully analyze the laws of adolescents’psychological development and fully understand the laws of adolescents’physical development and exercise acquisition.The purpose of this study is to start from the actual needs of physical education teaching and to fully understand the laws of psychological development of adolescent groups.After the review and analysis,the law of adolescents’sports acquisition is summarized and summarized,so as to form the system of adolescents’psychological development and sports acquisition law in physical education teaching,lay a good foundation for physical education teachers to implement teaching on the teaching objects of adolescent students in a targeted and efficient manner,and ultimately promote the benign development of school sports.

The Centenary of the CPC: Leading the Times by Grasping the Laws and Trends of Historical Development

Discussions on grasping the laws and trends of historical development take a fundamental theoretical position in the scientific system of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.Xi Jinping’s important statements have systematically answered such questions as what type of laws and trends of historical development should be followed,how did the Party follow the laws and trends of historical development in its centennial history,and how should the laws and trends of historical development be followed in a new era.The birth of the Communist Party of China(CPC),the victory of China’s War of Resistance against Japanese Aggression,the founding of the People’s Republic of China,and the unveiling of a new era for reform and opening up and socialism with Chinese characteristics are all the results of grasping the laws and trends of historical development.Over the past century,the Party has followed the laws and trends of historical development and continuously advanced the sinicization of Marxism on the basis of adhering to the unification between truth and values.In pursuit of“putting people first,”the Party has courageously been reforming itself and made relentless progress in the great endeavor of Party building.History shows that a keen appreciation of the laws and trends of historical development is an important sign of political maturity for a proletarian party.Only by applying Marxism according to current times and conditions will we keep abreast with the laws and trends of historical development.We should establish a broader concept of history and identify the laws and trends of historical development from the interactions and linkages between China and the rest of the world.We must recognize and promote the outstanding role of great leaders in steering the country in line with the laws and trends of historical development.

Law of Intestinal Development of Wanxi White Geese at 0 -9 Weeks Old

[Objective] To explore the law of intestinal development of Wanxi white geese at 0 -9 weeks old. [Method] A total of 120 Wanxi white geese at 1 day old were selected, and their law of development of intestinal weight and length was studied by feeding test and slaughter test. [ Re- sult] The growth of Wanxi white geese was slow in the early age, rapid at the age of 2 -5 wk, peaked at about 5 weeks old, and then slowed. The daily weight gain was around 25 g/d at the age of 7 -9 wk. Intestinal growth also peaked at 5 weeks old and almost developed fully at 7 weeks old. Thus, intestinal growth had a similar law with body weight. With the development, the ratios of the length of each intestinal segment to that of total intestinal tract did not vary largely. [ Conclusion] The study provides a theoretical basis for the production and development of germplasm resources of Wanxi white geese.

从“再现性策略”课程到“建构性策略”课程--当代职业教育课程的范式转变与发展趋势

改革开放以来,我国职业教育引进了多种先进课程理念,并发展起一些具有中国特色的课程模式,但多数教师没有理解背后的深层逻辑,致使在课程建设中遇到很多问题。该文从职业理解、能力内涵、知识概念、工作分析方法等角度对我国职业教育改革实践中的主要课程模式进行分析,归纳确认了“再现性策略”和“建构性策略”两种课程范式,并从课程目标、学习内容、学习理论基础、划分课程结构的逻辑、课程开发方法等方面进行了区分。该文建议,为实现职业教育高质量发展,需要实现课程范式的转变,即从基于传统学校教育的“再现性策略”课程转变为“建构性策略”课程。这一范式变化符合新职业教育法对技术技能人才成长规律的关注,体现了先进学习理论的要求。该文还提醒,高技能人才培养的课程应更加关注理论和实践的复杂关系。

Predicting the height of water-flow fractured zone during coal mining under the Xiaolangdi Reservoir

It is very important to determine the extent of the fractured zone through which water can flow before coal mining under the water bodies.This paper deals with methods to obtain information about overburden rock failure and the development of the fractured zone while coal mining in Xin'an Coal Mine.The risk of water inrush in this mine is great because 40%of the mining area is under the Xiaolangdi reservoir.Numerical simulations combined with geophysical methods were used in this paper to obtain the development law of the fractured zone under different mining conditions.The comprehensive geophysical method described in this paper has been demonstrated to accurately predict the height of the water-flow fractured zone.Results from the new model, which created from the results of numerical simulations and field measurements,were successfully used for making decisions in the Xin'an Coal Mine when mining under the Xiaolangdi Reservoir.Industrial scale experiments at the number 11201,14141 and 14191 working faces were safely carried out.These achievements provide a successful background for the evaluation and application of coal mining under large reservoirs.

台湾教改与“我们的课改”

前些年台湾一场教改被认为不成功。当地社会各界进行了尖锐批评。"我们的课改"跟它惊人地相似。我们不该也无需将它们两者简单类比。但如果进行适当的类比,认真思考它所提出的重要问题,汲取有益的经验教训,那么,对审视当前课程改革有实践意义,而且对教育学、课程教学论研究有理论意义。
