The development of the mud diggers
在过去，开发贻贝泥的技术不是那么令人满意，这导致了一些辉煌的人想出来的新思路，开发工具，以帮助改善农田工作的效率。“淡菜泥”制品，这意味着一种材料，可以从海底积累的牡蛎床。这种材料是到人类的生活水平发展的重要岛，因为它可以促进经济在一定程度的进展。随着知识和技术的发展，泥浆挖掘机逐渐成为在工作过程中越来越多的方便和有效的。具体的方法和操作泥浆挖掘机的程序已经解释详细文章。很多人的后代仍然在脑海中老泥铲土机的内存。总之，泥浆的力量是伟大的，它已帮助当地人民提高了工作效率和劳动成本节约在一定程度上。
“早期，更原始的挖掘机从后来的模型某些方面有所不同。这是在威尔莫特1867年观察到的进步编辑的机器只有约5英尺宽，这使底部较小区域的重新挖掘孔不得不砍掉前后挖掘机感动。“--泥挖掘者
以上款采用了历史思维-的连续性和变化，这可能与现在和过去某些方面的比较来判断的概念。在引用部件时，泥浆挖掘机正在取得进展，这可以在挖掘机的大小来显示。这是需要使用历史思维来分析世界事务。
This article has mainly introduces the history of the mud diggers. In the past, the technology to develop the mussel mud was not so satisfying, which has led to some brilliant ones to think out of the new ideas to develop the tools to help to improve the efficiency of working in the farmland.“Mussel mud” has been explained in the article, which means a kind of material that can be gained from the submarine accumulations of the oysterbeds. This kind of material was important to the development of the living standards of human beings in the island, for it can promote the progression of the economy to some degree. With the development of the knowledge and the technology, the mud diggers gradually became more and more easy and effective in the working process. The specific methods and procedures of operating the mud diggers have been interpreted in the article in detail. Many generations of people still had the memory of the old mud diggers in the mind. In conclusion, the power of the mud was great, which has assisted the local people to improve the working efficiency and save the cost of labor to some extent.
“The early, more primitive diggersdiffered in some respects from latermodels. The machines which wereobserved at Wilmot by the editor of theProgress in 1867 were only about fivefeet wide, which permitted the excavationof a smaller area of bottom before anew hole had to be cut and the diggermoved.” ——The Mud Diggers
The above paragraph has used the concept of the historical thinking—the continuity and change, which may be judged from the comparisons between some aspects in the present and the past. In the citation part, the mud diggers were progressing, which can be displayed in the size of the diggers. It is necessary to use the historical thinking to analyze the matters in the world.
