基于对传统钢铁生产节能减排的思考，探讨了使用清洁能源炼钢的问题，提出了太阳能光伏炼钢概念在技术层面上的特点：一是光电转化，转换过程直接迅速，且不会伴随任何物质转变和化学变化；二是"脱网"，即不与常规的输供电电网相搭接，以保证系统在能量方面的独立性。

Significant processing steps can include: a phase changes involving either the desired molecule or the solvent, inert carrier or vehicle, e.g., dissolution, crystallization, evaporation, sublimation, distillation or absorption; b a phase separation such as filtration or centrifugation; c any chemical change involving the desired molecule, e.g., removal or addition of water of hydration, acetylization, formation of the salt; d an adjustment of the solution containing the molecule such as adjustment of pH or pO2; e a precision measurement of contained or added BPC components, in-process solutions, recycled materials is performed, i.e., weighing, volumetric measuring, optical rotation, spectrophotometric determinations, etc.; and f changes occur in surface area, particle size, or lot uniformity, e.g., milling, agglomeration, blending.
