Meanwhile, in the process of operation, oil film is used for lubrication and anti-friction between main bearing and the main journal, for the load, main journal may deform under the action of upper and lower bearing shells; the main function of the thrust bearings on both ends is to prevent the crankshaft from axial channeling.

The carbon emissions in this stage are mainly the production and processing of all kinds of building materials.
Building materials required in the building include not only steel, concrete which directly constitute the construction entity, but module, scaffold and other auxiliary materials of construction.
The CO2 emissions in building construction stage is produced by construction technology and the transportation of building materials, machinery equipments and solid waste produced in the construction process [8].
However, the recycling of building materials and waste can reduce some carbon emissions.

Experimental Procedures 2.1 The Preparation and Performance of Experiment Materials All the experiment materials were made in the Zhenjiang HuaLong Continuous Cast Iron Limited Company, their types were all LZQT500-7.
The mechanical behavior of ADI materials are listed in Table 2.
The big error existed in experiment may be caused by the uneven internal organization such as shrinkage defects of ADI materials and the imprecise of the machining and measuring process.

All the raw materials were milled by pin mill or ball mill and then sieved with N0. 40 sieve.
After sieving, raw materials were completely dried at 100±10°C for 24 hrs in the drying oven.
Result and Discussion Table 1 shows the average size of particles and specific surface area of the raw materials used for plasticity index test.

Fig. 1 Metallurgical structure of failure coupling material After Chemical composition and microstructure analysis, the mechanical properties of failure coupling materials were tested.
The strength and toughness of the materials reach a higher level and match well.
It was surmised that main covered layer materials were a large number of completion fluid sediments and a small amount of certain oxides.
