Question

哪位英语好的人帮帮忙，看看我的英语翻译有没有语法错误，呵呵！！非常感谢啦！！

In mathematical modeling theory, differential equation model is an essential part of, differential equation model is the main types of the famous population growth model, infectious disease model, the economic cycle model, also includes this paper will focus on research of ecological model and so on.
This paper mainly discuss two populations between predators and baits of ecological system .Before establish model, assuming some convenient conditions for the actual model, and according to the existing data and software programming are model and analysis separately. When Italian biologist U.D'Ancona in study fish variation rules, he found that during World War I, Mediterranean Sea ports the proportion of carnivorous fish caught number and total amount not only has no dropped because of the war, but significantly increased, the proportion of bait amount is decreased obviously.
Chapter 1 without considering artificial predator, the growth of baits is accord with Malthus equation, when predators exists ,unit of time the quantity of swallowing each predator to bait is direct proportional to the bait population scale, discussed through the ratio coefficient .
Chapter 2 considering artificial predator, predators and baits will block each other, the growth rate can’t simply present direct ratio state, so assume a capture ability coefficient for m, this time predators and baits are accord with Lotka-Volterra model.
Chapter 3 through the establishment of grey forecasting model and a linear regression model predict the discussed data, and give reasonable inspection process to prove that data are accord with current trends.
Chapter 4 as a summary, given the major significance.
在数学建模理论当中，微分方程模型是不可或缺的一部分，微分方程模型的主要类型有如著名的人口增长模型、传染病模型、经济周期模型、还包括本文要重点研究的种群生态模型等．
本文主要讨论两个种群生态系统之间捕食者与食饵情况的研究．在建立模型之前，假设了一些方便于实际模型的条件，并根据现有数据和软件编程分别进行模型的求解与分析．意大利生物学家U.D’Ancona在研究鱼类变化规律时，发现第一次世界大战期间,地中海各港口捕获的食肉鱼数量与鱼类总量比例不但没有因为战争的原因下降，反而明显增加，而食饵的比例却明显下降．
1. 不考虑人工捕食时，食饵的增长规律符合Malthus方程，当捕食者存在时，单位时间内每个捕食者对食饵的吞食量与食饵种群规模成正比，通过比例系数讨论；
2. 考虑人工捕食时，捕食者和食饵之间会有相互阻滞的情况，增长率也不会单纯呈现正比状态，这时就假设一个捕获能力系数为 ，此时捕食者与食饵之间符合Lotka-Volterra模型；
3. 通过建立灰色预测模型以及一元线性回归模型对所讨论的数据进行预测，并给出合理的检验过程来证明数据均符合当前的变化趋势；
4. 作为总结，给出了论文的主要意义．

Answer 1

大致的帮你改了下，你的问题很多。你的介词不会使用，还有定冠词the 不会使用。再个就是句子表达混乱，尤其是从句没有理解吃透。条件需要多看。
最后，你需要多下语法，多体会，吃透才行的。
希望对你有帮助。
Differential equation model is an indispensable part of In mathematical modeling theory. There are the main differential equation model like the famous population growth model, infectious disease model, the economic cycle model and includeing this paper will focus on research of ecological model and so on.
This paper mainly discuss two populations ecological system between predators and baits.Before establishing model, it is assumed that some conditions is convenient to the actual model and according to the existing data and software programming model and analysis separately. When Italian biologist U.D'Ancona study fish variation rules, he found that Mediterranean Sea ports the proportion of carnivorous fish number caught and total amount not only hasn’t been reduced druing at the world one.It has been abvously increased and the proportion of bait amount has been decreased as the war stoped..
Chapter 1 The growth of baits is consistent with Malthus equation without considering artificial predator.when predators exists the quantity for each predator swallow tobait in the unit time is proportional with direct ratio to the bait population scale by discussing the ratio coefficient .
Chapter 2 considering artificial predator, predators and baits will have block situation, the growth rate can’t simply present direct ratio state, so supposing a capture ability coefficient for m, this time predators and baits are consistent with Lotka-Volterra model.
Chapter 3 By predicting the establishment of grey forecasting model and a linear regression model discussed data and bring the reasonable conclusion inspection process to prove that data are consistent with the current trends.
Chapter 4In one word, the article has given the major significance.

不用谢，如有疑问，可再问。

Answer 2

小小的有点怀疑你是自动翻译的。别介意哈

追问

是有的翻译的，所以才帮忙翻译的

追答

读着别扭，虽然我不是专业英语的翻译好手，但也知道你这里面的错误，还是，不少。

Answer 3

第一行part of后的of去掉。accord with = in accordance with,
最后一段 as a summary = in summary. given the major significance = the major significance is given.
