Application Research of Sonar Detection Method in Melting Exploration at the Bottom of Piles

Karst landforms are widely distributed in China,and are most common in Yunnan,Guizhou and Guangxi.If the development of karst caves at the bottom of the piles cannot be accurately ascertained before the construction of bridge pile foundations,accidents such as hole collapse,slurry leakage,and drill sticking will easily occur.In this paper,the principle and method of sonar detection for detecting karst caves at the bottom of bridge piles was introduced,and the sonar detection data and the cave situation at the bottom of the pile during the construction process in combination with the case of Yunnan Zhenguo Highway Project was analyzed,which verifies the practicability and reliability of sonar detection method reliability.

A Brief Analysis of the Application of Situational Teaching Method in Primary School Music Class

Music situational teaching method aims to mobilize the students’thoughts in a natural state so as to enhance the attractiveness and efficiency of music classes.In the process of this method,some specific situational are designed according to the characteristics of music and under the guidance of psychology,methodology,pedagogy and other theories,and various sensory organs are employed.Different from traditional teaching method,situational teaching method creates learning situational for students,which is consistent with the characteristics of primary school students’physical and mental development and maximizes students’experience and feeling of music.

The Comparison of Tasked-based Teaching Method and Situation Teaching Method in Lexical Learning in Senior High Language Teaching

there are many teaching methods in current teaching procedures,such as the whole language teaching method;communicative teaching method;cooperation teaching method;situation teaching method;tasked-based teaching method;content-based teaching method;competence-based teaching method multiple intelligence teaching method and other teaching methods.This article depicts the usage and comparison of the tasked-based teaching methods and situation teaching method in lexical learning in senior high language leaching.This article first talks about the definition and feature of these two teaching methods.Then through observing the students using different methods,I aim to compare these two methods in order to find out the similarities and differences between them when students are learning vocabulary.Making further study on the teaching methods,I would like to take good advantage of them in lexical learning in senior high classes in hope that we teachers can inspire students'thinking,arouse their desire,active the atmosphere and help them have a better and simpler command of the vocabulary they obtained in the class.

The Comparison of the Control Effect on the Varroa Mite with Different Ways of Raising Management

[Objective] The aim was to o research the control effect to Varroa destructor and Tropilaeplaps clareae whit new raising management methods, and reduce the pollution caused by drug treatment of bee. [ Metkod] We took the method that was replace the hive and comb on test col- onies with the comb Formalin soaking liquid used three days after the dry and sterilization in advance with the hive. The test groups were 10 colonies randomly selected from the disinfected comb in the breeding. This was the first kind of method. The control groups were 10 colonies randomly se- lected by the conventional breeding management methods. From January 20th, statistic analysis on parasitic situation of bees once every month be- tween the two methods, and take corresponding measures to prevent and control the varroa mite according to the varroa mite parasitic number in time, then the control effect of mite between the two methods were compared with. [ Result] The results showed that the first method was better than the second one in V. destructor, the control time of T. clareae delayed about one month [ Conclusion] Good breeding method could restrain I V. destructor and T. clareae parasitism, speeded up the colony development, and reduced the pollution of chemical drugs on bee products, regar- dod as a kind good method of controlling bee mites to make use of the feeding and management technology.

Research on English Language and Literature Teaching Strategies Based on Situational Teaching Method

The teaching of English language and literature not only focuses on developing students’English language proficiency but also emphasizes their understanding and cognition of the cultural connotations behind the English language.This dual focus aims to cultivate students’cross-cultural communication skills and practical English skills.The application of the situational teaching method can create corresponding learning scenarios based on English language knowledge,thereby enriching students’learning experiences and understanding within these scenarios.This method has significant advantages in enhancing the effectiveness of English language and literature teaching.Consequently,this paper first analyzes the significance of applying the situational teaching method in university-level English language and literature instruction.It then proposes several strategies for implementing this method,with the goal of enhancing students’language awareness,cultural literacy,and comprehensive English skills.

The application of situational teaching method based on the Chinese linguistic literature

The teaching properties and the teaching modes of the Chinese linguistic literature compared with the other courses have certain particularity, and in the course teaching, we should give full play to the subjectivity of the students, but also play the practicability of the course teaching through the construction of students＇ knowledge slructures and the shape of their ideology. The author thinks that contemporary Chinese language and literature teaching should break the limitation of the traditional teaching mode, and we should guide the students to play the subjective consciousness and the consciousness of the emotional experience of the course learning in the cross-national literature and artistic context with various forms and rich contents, and help the students easily and autonomously integrated into the Chinese language and literature teaching.
