The major technologies used include increasing compression ratio, changing spark advance Angle and using intake pulse turbo-charging.

主要采取了提高压缩比、改变点火提前角及采用进气脉冲增压技术。

It is shown that with adjusted ignition Angle of advance, larger compression ratio and appropriate preheating of the mixture, better fuel economy can be achieved.

指出调整点火提前角、提高压缩比以及适当预热混合气等，可以提高掺烧甲醇时燃油的经济性。

Finally, the importance of compression in advance in construction of scaffold has been emphasized and values have been given.

最后，阐述了施工中支架预压的重要性并给出了预留沉降值。
