求翻译：合成工艺：双酚A型环氧树脂的合成方法有两种：一步法和二步法。一步法又可分为一次加碱法和二次加碱法。二步法又可分为间歇法和连续法。是什么意思？

Synthesis: the synthesis of bisphenol A epoxy resin in two ways: one-step and two-step. Can be divided into a one-step increase plus soda and secondary alkaline. Two-step method can be divided into intermittent and continuous method.

Synthetic craft: bisphenol A type epoxy resin synthetic method has two forms: The first step and 2 step. A further law which may be classified as an alkali law and 2 times the soda. Step 2 is further divided into intermittent law and continuous.

Synthesis craft: The double phenol A epoxy resin synthetic method has two kinds: One-stage process and two steps.The one-stage process may divide into an alkalizing law and two alkalizing law.Two steps may divide into the batch process and the continuous process.

Synthesis: synthesis of Bisphenol-a epoxy resin has two kinds: one step and two step. One step can be divided into a and twice with alkali and alkali method method. Two steps can be divided into batch and continuous process.
