For shorten the product design cycle and saved the cost, the 2.5L reciprocating compressor crankshaft is parametric designed by Pro/E. stress analysis about crankshaft during a revolution was done to check each dangerous cross-section based on dynamics, materials mechanics.
The static strength of journal can be checked by: (7) where σ-1 is symmetric bending fatigue limit (MPa) of crankshaft material; σ is normal stress (MPa) of dangerous point, [n] is the allowable safety coefficient, [n] = 3.5 ~ 5.
Journal deflection θ= 0.00021rad≤ [θ] = 0.00031 rad, rigid is enough.

Introduction Nano-material is an important research field of nano-science and developed in the mid-80s.
Nano-material was known as “the most promising materials in the twenty-first century” [1-2].
Its properties is not only differred from atoms, but also defferred from bulk materials[3].
At the same time, surface active agent can hinder the aggregation of nano-materials.

The BPs are typically made from conductive metallic, carbon and polymeric materials [4].
Various bio-based carbohydrates - fructose, glucose, sucrose, starch, cellulose, etc. can be used as raw materials for the production of HMF [13].
Solid humins we used as raw materials for active carbon preparation [14].
