The logical characteristic of model-based reasoning is the reliable perfect logical relation is established between prototype and model, model and theoretical hypothesis.
模型化推理的逻辑特征在于在原型与模型之间，以及模型与理论假设之间尽可能地建立起可靠的、完善的逻辑联系。
The reasoning is usually based on a discounted-cashflow model; a lower bond yield means a lower discount rate and thus a higher present value for shares.
