别再把工程报告Discussion写成数据复述了

Engineering discussion sections fail when they re-list data instead of interpreting significance. Natural engineering writing is about causal logic, not number-dumping.

你盯着屏幕上那行“The Fig 3 shows the temperature increased by 5%”，心里发虚。你知道这不行，但你 don't know how to fix it. 大多数留学生把 Discussion 写成 Result 的加长版。You list the numbers again, you list them slightly differently, and you pray the professor doesn’t notice you haven't actually said anything new. That is exactly why your writing feels stiff and robotic.

The core mistake is treating Discussion as a data repository. It isn't. A discussion section exists to answer one question: "So what?" If your experiment shows the bridge vibrated more under load, that’s a result. The discussion explains why it vibrated, whether it’s safe, and what it means for the design. Without that interpretation, you are just reading your own graphs back to yourself. This is a logic gap, not a grammar problem.

Look at this typical ❌ original sentence: "The experimental results demonstrate that the yield strength of the alloy is 450 MPa, which is higher than the literature value of 400 MPa." It’s technically correct, but it’s dead. It just compares two numbers. Now look at the ✅ rewrite: "The observed yield strength of 450 MPa exceeds the reported 400 MPa, suggesting that the grain refinement process during casting enhanced dislocation density, thereby improving resistance to plastic deformation." See the difference? The first is a fact; the second is an engineering argument.

Another place where writing goes off the rails is passive voice abuse. ❌ "It was observed that the material fractured at 50 N." ✅ "The material fractured at 50 N, likely due to the micro-cracks identified in the SEM images." The first sentence hides the agent and sounds like a robot logging data. The second connects the fracture to a specific physical cause. In engineering, causality is king. If you don't explain the mechanism, your discussion is just a list of symptoms.

You might think that using complex words makes you sound more academic. It doesn't. It makes you sound like you're hiding behind jargon. ❌ "The efficacy of the proposed algorithm was validated via the simulation model." ✅ "The simulation confirmed the algorithm works as intended, reducing processing time by 20% without sacrificing accuracy." Simple, direct, and confident. Real engineers speak in plain English. If you can't explain your finding clearly, you don't understand it well enough.

This is where you stop wasting time on manual copy-pasting. I don't rewrite every paragraph by hand anymore. I draft my interpretation, then I run it through easydue to check if the logic flows naturally. It helps me spot where I’m still just listing data instead of arguing a point. The tool doesn't write for you; it makes sure your own logic lands correctly. That’s the difference between a polished draft and a professional argument.

Stop trying to sound like a textbook. Sound like an engineer who knows their work. The best discussion sections are sharp, causal, and direct. They tell the reader why the numbers matter. If your paragraph doesn't change how the reader thinks about the design, cut it. Your English is only "unnatural" because your thinking is too vague. Sharpen the logic, and the language will follow.
