大型船舶模型是完全依照真船的形狀、結構、色彩，甚內飾部件，嚴格按比例縮小而制作的比例模型。因為一旦某個零件比例不同，船模因為其真實的再現原船主要特征，做工精良，其本身蘊含著的是船舶文化，具有很高的收藏價值。一套用心收藏的船模甚可以完整真實的再現一個船舶公司，一個船舶的歷史。

A large-scale ship model is a scaled model made strictly according to the shape, structure, color, and even interior components of the real ship, and is strictly scaled down. Because once a certain part proportion is different, the ship model, due to its authentic reproduction of the main characteristics of the original ship, is exquisitely crafted, and it contains ship culture, which has high collection value. A set of carefully collected ship models can even fully and realistically reproduce the history of a shipping company and a shipping brand.

大家心目中的船模是精良細致的，但不過是無數零件的堆疊和拼裝而已，只要有點耐心，誰都能拼起來，這有什么難的；拼好的模型也不能下水，只能擺在家里，有錢人消遣時間的玩物罷了。

The ship model in everyone's mind is exquisite and meticulous, but it is just the stacking and assembly of countless parts. With a little patience, anyone can put it together. What's the difficulty of this; The assembled model cannot be put into the water, it can only be placed at home as a leisure item for wealthy people.

我們且不說安裝船模的過程中上膠、補色、修剪以及細小精密零件的拼接有多困難，要是要制作一款船模呢？并且同時還附帶某些實際性能呢？

Not to mention how difficult it is to glue, add colors, trim, and assemble small and precise parts during the installation of a ship model. What if we want to make a ship model? And it also comes with some practical performance?

制作専業的船模，需要根據船體的型值表和型線圖，按一定比例縮小制造的船體模型，是預報實船航行性能和輔助船舶科研教學的重要工具。

To produce a specialized ship model, it is necessary to reduce the size of the manufactured ship model to a certain proportion based on the ship's shape value table and line diagram. This is an important tool for predicting the actual ship's navigation performance and assisting in ship research and teaching.

作為實船試驗的近似替代品，船模的可靠性(即動力相似性)與它們的幾何相似性密切相關，因此船模曲面不僅要求光滑，而且要求具有較高的幾何加工精度。由于船模曲面屬于大型對稱自由曲面，目前手工放樣的制作方式不但加工效率極其低下，而且也難以保證船模曲面的加工精度。

As an approximate substitute for actual ship testing, the reliability (i.e. dynamic similarity) of ship models is closely related to their geometric similarity. Therefore, the surface of ship models not only requires smoothness, but also requires high geometric processing accuracy. Due to the fact that the ship model surface belongs to a large symmetrical free form surface, the current manual layout method not only has extremely low processing efficiency, but also is difficult to ensure the machining accuracy of the ship model surface.

目前，公司級別的船模制作都已經充分利用現有計算機輔助設計(ComputerAided De—sign，CAD)/計算機輔助制造（Computer Aided Manufacturing,CAM)/計算機數字控制(Comput-Numerical Control，CNC)一體化技術，提高船模曲面的加工效率和精度，制作出更加精良的船模。

At present, the production of ship models at the company level has fully utilized the existing computer-aided design (CAD)/computer-aided manufacturing (CAM)/computer numerical control (CNC) integrated technology to improve the machining efficiency and accuracy of ship model surfaces and produce more refined ship models.

除了可以試驗，同時，它也是一種船舶/船塢模型的復制形式。可用于大型展覽，它們也是船舶的一種推廣形式。

In addition to being able to experiment, it is also a replication form of ship/dock models. Can be used for large-scale exhibitions, they are also a form of promotion for ships.

對于傳播和設備制造商來說，如何迅速地將他們的產品推向市場是為了讓更多的人了解產品，而參與展示是一種非常有效的方式；可以讓更多的人對船舶/船塢模型有一定的了解。大型船舶模型

For communication and device manufacturers, how to quickly push their products to the market is to let more people understand the products, and participating in exhibitions is a very effective way; It can provide more people with a certain understanding of ship/dock models. Large ship models
