Help with chinese sentences. Hello there! I'm doing some chemical stuff translation from russian to chinese, so I need some help, if its possible. The senteces are: 1) The reaction proceeds slowly and imperfectly. My translation is: 这个反应的过程是比较慢的和不完善的. Is it OK? I also wanted to use 得，like 反应进行得比较慢... but I don't know how to use 2 adverbs. Should it be 反应进行得比较慢并不完善 or 反应进行得比较慢和不完善? 2) The choice of site for realisation of the project is based on materials availability, well-developed infrastructure, energy resources low-cost and proximity to customers. 选择项目实现的地方有几个原因：原料的存在，发达的基础结构，能源的低价格，消费者和地方的接近. Totally not sure about this one. Thank you in advance!
