Abstract: the middle school science and technology education to set up science education curriculum, extracurricular science activities as the main carrier. Through the teaching scientific basic knowledge and skills to students, cultivate students advocating the spirit of science, the formation of scientific thinking methods, improve the students' scientific quality, so as to promote the scientific quality improvement. Local educational administrative departments and schools should fully realize the science and technology education is an integral part of the comprehensive implementation of quality education, and actively carry out science and education to the students, the dissemination of scientific thinking, cultivating students' innovative spirit and practical ability to promote the healthy development of students has important significance, must give this work in an important position, and grab results. In the global financial crisis, many enterprises can't adapt to the environment change, have fallen. There are a large number of small and medium-sized enterprises, the lack of independent research and development capacity, which will not be able to adapt to the change rapidly in the world. The continuous innovation, continue to embrace change, creative enterprises, but can withstand the harsh environment in the financial turmoil, survive.
