The practice was as follows: a long column was erected first (the length varied from the actual conditions of bridge), and the tail of the near fir is firmly fixed with a long column using flax rope or thin bamboo strips, and then the swing is fixed by connecting the lower part to the ground; after the two swing pillars in front of the abutment are fixed, a wooden beam is connected with the upper part so as to form the shape of "swing framework", which is provided for carpenters to go up and down and also support all wood materials in the "tri-segment arch" and the "five-segment arch".
In this part, tri-segment arch system and five-segment arch system realize a mutual occlusion and integrate into a whole body, so as to commonly carry the key of the load.
The materials of the up and down inclined blades in the five-segment arch system were relatively small and also different in length.
The materials used in the plain wood of tri-segment arch and five-segment arch were great, and also the head and tail of wood materials were overlapped.

They are technically important because mixed systems provide a way of tailoring microdomain properties through simple composition variations; new structures can be obtained here by changing the system composition, rather than through synthesis of new materials.

Optimization of the preparation technology of resistant starch of cowpea using response surface methodology Wei-wen Huang1,2,a, Wei Wang1,b, Ji-lie Li1,c and Zhong-hai Li1,2,d 1Department of Food Science and Technology, Central South University of Forestry and science, Changsha, Hunan 410004, PR China 2National Engineering Laboratory for Rice and Byproducts Processing, Changsha, Hunan 410004, PR China ahww5626@163.com,bwanderwish@126.com,clijilie12@163.com,dlizh11@163.com Keywords: resistant starch, response surface methodology, optimization, preparation technology Abstract: Response surface methodology was used to optimize the preparation technology of resistant starch (RS) production by raw cowpea bean starch.
RS3 in beans is important raw material and has been widely used in food, textile, chemical and packaging materials and other fields [13, 14].
In this paper, taking cowpea bean as raw material for preparing starch, cowpea RS preparation process adopting the pressure heat coupling enzymatic hydrolysis was optimized by using response surface methodology and the key factors on the influence of preparation of RS yield were researched.
Materials and methods Materials Cowpea: commercially available; cowpea starch: self-product; heat-resistant α-amylase (20000 U/mL): Shandong Anke biotechnology limited; pullulanase (400 U/mL): Novozyme company in Denmark; pepsin (P7000): Sigma company in American; other reagents were analytical pure.
