The chemistry of weld metal is always governed by the electrochemical changes at the weld pool flux interface [1-6].
Some papers found also even small changes in the flux or coating chemistry could lead to substantial variations in the metallurgical behavior of the obtained systems [17,18].
The CaMgSi2O7 phase has a melting temperature below 1000°C and a tetragonal crystalline structure [41].

Importance of interdisciplinary technique and education Chatzitheodoridis showed that Apart from the conventional approach of teaching courses from basic sciences (physics, chemistry, and biology), engineering and information sciences, we would also need courses on psychology and public awareness, environmental and anthropological sciences, etc. [3].
Based on design concept of existing devices, the design methodology can generate all possible topological structures of mechanical devices that perform the same or similar tasks as available existing designs, and subject to certain design requirements and constraints.
The topological structure of this mechanism includes six members and seven joints.

Introduction Room-temperature ionic liquids (RTILs) are a new class of solvents, which have received much attention in many fields of chemistry owing to their unique physicochemical properties, such as high fluidity, high thermal stability, extended temperature range in the liquid state, low toxicity, high ionic conductivity and others [1-2].
For these reasons, ionic liquids are actively being explored as environmentally benign solvents in organic synthesis and catalysis [3], but they have been utilized little in the areas of synthetic coordination chemistry.
Only in recent years, the use of ionic liquids in the synthesis of coordination structure field has been gradually explored [4-8].
Li et al. [8] have synthesized of the coordination polymer [Cu(I)(bpp)]BF4 in 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid and found that BF4- anions entered the final structure as a charge-compensating species.

Introduction Studies of organometallic polymer chemistry developed rapidly since Arimoto and Haven reported the vinyl radical polymerization of ferrocene in 1955[1].
Because the space environments of protons with similar structures in polymer I are just slightly different, the absorption peaks with similar chemical shifts overlay each other and form broad multiple peaks.
There is only one vinyl group in the monomer I, which leads to the linear structure of the polymer I.
