For the important basic subject of primary school mathematics, teachers need to examine the teaching methods and teaching content, reconstruct the teaching mode according to the new curriculum standards and students reality, especially pay attention to the diversified research of problem solving methods, so as to tap students learning potential and enlighten their wisdom, promote the improvement of mathematics learning level. Specifically, in the teaching process, teachers should change their teaching concepts in time, encourage students to think actively, focus on consolidating basic knowledge, guide students to use flexibly, actively guide innovative research, cultivate students divergent thinking, carry out group cooperative learning, achieve the collision of students thinking, and pay attention to the application of life practice to ensure the effect of thinking expansion training.展开更多

Usually, each maker has two feed-pipes, it adopts fixed and one-to-one fashion, with the flexible manufacturing system extending, and it＇s original fashion unable to satisfy the needs of a wide range of cigarette brands already, so it cry for a viable and reliable substitute. This paper creatively bring forward the optimized fashion of duct net about filter-rods based on topology structure, it adopts Freud＇s algorithm and improved-separated algorithm in order to achieve the optimized route, it has a apparent effect to improve the transport stability and reduce the transport time of filter- rods.展开更多

Economic change and social transformation puts forward new requirements for the social security system reform. This paper studies the theoretical basis of the social security system reform, analyzes the status quo of China＇s social security system and the existing problems and experience in social security system of other countries for reference, on the basis of perfecting China＇s pension, medical, unemployment and other social security system, the construction is suitable for the situation of our country＇s social security system with Chinese characteristics, ensuring and improving people＇s livelihood, the achievements of reform and opening to the public to achieve genuine sharing is of great significance.展开更多

Firstly, we give the representation theorem and prove the uniqueness of solutions for the boundary value problem. Afterwards, by using the method of successive iteration, the existence and estimates of solutions for the boundary value problem are verified. The above problem possesses the important applications to the Tricomi problem of mixed type equations of second order. In this article, the proof of HSlder continuity of a singular double integer is very difficult and interesting as in this Section 4 below.展开更多

The researchers seek to uncover： （1） the generic structure of MA theses, （2） the generic structure of Ph.D. dissertations, （3） any probable differences between these two groups. ＂statement of the problem＂ section of 48 MA and Ph.D. dissertations from 2001 to 2008 in Teaching English as a Foreign Language （TEFL） at Mazandaran, Tehran and Allame Tabatabaee universities was selected. For the quantitative method of data analysis, frequency counts, and for the qualitative method, genre analysis was used. Samples were categorized both according to the year they were written and the university they belonged to. The study enjoyed a second rater with inter-rater reliability about 0.93. Results revealed that there was a significant difference in writing ＂statement of the problem＂ in different time periods and different universities in the sense that students in different degrees, time periods, and universities employed quite different generic structures for writing. However, postgraduates in recent years （especially 2005-2008）; regardless of their degree and university, seem to use much more similar generic structures which indicates a general genre awareness.展开更多

However, in the process of clinical treatment, according to different situations, the types and types of drugs required are also different, which puts forward a high requirement for pharmaceutical workers. We should have the courage to innovate and break through, and improve the quality of drugs from the selection of API, production plan, technological process and other aspects. In addition, with the rapid development of pharmaceutical technology in China, the recycling of pharmaceutical waste can not be ignored. This plays a vital role in the sustainable development of the pharmaceutical industry.展开更多
