And the questions are all worth being thought.
ⅠThe development of philosophy of technology and distance education
Distance education refers to the teachers and students in the separation condition using radio, television, written materials, audio-visual materials, computer courseware, network and other media to implement the education.
Take seven core journals in CSSCI of distance education " Electrochemical Education Research" " China Audio-visual Education ", " Open Education Research ", "Modern Education Technology", "Modern Distance Education", " Remote Education Magazine ", " Modern Distance Education Research ", as example, Seven core journals published 1582 papers in 2011 and teachers of TV university system has published 116 papers, accounting for more than 7.3% (see chart 1).
Table 1 The statistics of 2011 RTUV system paper published on core journals of distance education* Journal name Annual number (published papers) Number of RTUV system (published papers) ratio remark Electrochemical Education Research 284 8 2.8% 2011 China Audio-visual Education 373 21 5.6% Open Education Research 123 22 17.9% Modern Education Technology 438 8 1.8% Modern Distance Education 113 30 26.5% Remote Education Magazine 151 10 6.6% Modern Distance Education Research 100 17 17.0% * This form of data from Hownet periodical data query statistics in 2011 The mainly reasons cause the present situation of RTUV system teachers' research ability and level include the following: The first is historical reasons.
The two aspects of teachers are lack of professional knowledge and research ability, this also reflected in the curriculum teaching material update, there are such outstanding problems are cycle is long, content is old etc.
In addition except the special study, teacher needs to research students, teaching materials, and reflect on their teaching.

Emerging trends in extrusion-based additive manufacturing (AM) focus on improving the mechanical performance of pristine polymers with high strength reinforcing materials.
In conclusion, a drastic improvement in mechanical performance can be obtained through the hybridisation of manufacturing methods and needs further investigation towards the compatibility of adhesive materials with FDM polymers.
Dahmen et al. [13] evaluated the joint strength of T-joints, comparing the joint strength of traditional bonding materials with 3D-printed dual-cured epoxy bonding.

Object teaching product design, including online courses, multimedia courseware and other teaching media, teaching materials, teaching environmental and laboratory.
Simple teaching products, such as slides, slides, sound recordings, and multimedia courseware and other teaching materials, generally by classroom teachers to design and make your own.
Teaching more complex products, such as audio-visual materials, large multimedia courseware, online course development, and teaching environment, such as design and development, the need to organize a dedicated development team to complete.

Introduction
Along with the development of science technology and economic, the train speed becomes more and more quick.
The silencer length is 1.25m, and lined with glass silk as sound absorbing material.
The whole muffler with four the same channels divided by three slices of sound-absorbing material, as shown in Figure 1.
Meanwhile, collision and friction occurred between fluid particles and wall and produced a certain amount of pressure loss(Friction loss), the size of this resistance has a relationship with the Air speed, the roughness of sound-absorbing material Etc.
