Abstract.
In the new rapid design method, product modular configuration is the key issue, which needs the proper clarification of product module.
If can meet the demand of customer, output the BOM (Bill of Materials) of production requirements to the production sector as the rapid design above.
Moreover, we can directly output the BOM (Bill of Materials) table from the model and transfer it to production department to realize the rapid design of the product.

Synthetic fuels, made from coal, natural gas and biomass, such as synthetic natural gas as raw material called GTL diesel.
The main problems have been in connection with cavitations on fuel injection pumps, blocking of fuel pipes and material choice for rubber seals.
The cooling effect with mechanol should be the key factor to effect the Nox formation[14].

PLGA is one of the most common group of synthetic biomaterials which are used to delivery BMPs.[8] It has been utilized in biomedical applications for several decades, and also recently for bone tissue engineering.[9-11] PLGA beads have been mixed with BMPs to produce accelerated bone regeneration in a bone defect.[12] BMP-2 has also been delivered from PLGA bioerodable particles mixed with either a carboxymethylcellulose or a methylcellulose carrier.[13] This matrix was used in a rabbit cranial defect to provide bony bridging.[14] The conventional strategy in growth factor therapy for orthopedic applications is to administer the agent in the form of a large dose by either single or repeated injections but in such applications a considerable proportion of the agent was reported to be lost through leakage and/or loss of bioactivity. [15]Encapsulation of growth factors in carrier structures, therefore, could be of utmost importance in protecting the bioactivity of the agent and prolonging
