waterfall model 中文意思是什麼
waterfall model
解釋
瀑布模型 軟體開發過程模型的一種，包括概念階段、需求階段、設計階段、實現階段、測試階段、安裝和檢查階段、操作和維護階段，這些階段按次序進行，可能有部分重疊，但很少會迭代。-
In fact, every circle of its process is a simplified waterfall model
事實上它的每一次迭代都是一個簡化了的瀑布模型的開發過程。 -
From a testing perspective, the waterfall model offers one huge advantage over the other models presented so far
測試界有這么一種觀點， 「瀑布模型」相對于現今其它的模型有著巨大的優勢。 -
A project using the waterfall model moves down a series of steps starting from an initial idea to a final product
一個使用「瀑布模型」的項目，從起初的概念一直到最終產品，需要一步一步的經過一連串的步驟往下走。 -
Variations of the waterfall model loosen the rules a bit, allowing some overlap of the steps and the ability to back up one step if necessary
某些「瀑布模型」的變種放寬了這一原則，允許步驟間的交迭，如果需要的話還可以返回到上一步。 -
From an agile point of view, it is not advisable to understand all the requirements at the beginning of a project, analyze them, and then develop the architecture for the whole system like in a waterfall model
從敏捷的角度看，以下這些做法是不明智的：在項目開始時了解所有需求，分析這些需求，然後為整個系統開發體系結構，就像在瀑布模型中一樣。 -
The waterfall model is a software development model first proposed in 1970, in which development proceeds linearly through the phases of requirements analysis, design, implementation, testing ( validation ), integration and maintenance
譯文：瀑布模型的軟體開發模式是在1970年首先被提出的，在發展中完善，通過線性階段需求分析、設計、實施、測驗（驗證） 、集成和維護。 -
The design keeps to the classic life cycle of software engineering ( waterfall model ). according to software analysis, software design, software code and software maintenance, the design is divided into nine processes such as define systematic goal, feasibility analysis, demand analysis, outline design, design, software code, software test in detail, software maintain
該設計遵循了軟體工程中軟體生命周期法（瀑布模型） ；按照軟體分析、軟體設計、軟體編碼、和軟體維護等過程，系統分為定義系統目標、可行性分析、需求分析、概要設計、詳細設計、軟體編碼、軟體測試、軟體維護等九個階段。 -
More and more software organizations are moving away from the waterfall model of the life cycle to an iterative approach
越來越多的軟體組織開始從瀑布式模型向迭代式模型轉變。 -
According to different water phenomena, we use two different method to produce waves source : the first method is by specifying the boundary conditions and initialization conditions, this method simulate the dam breaking, reflection and diffraction of water waves ; the second method is by specifying disturbance model, this method simulate water droplets, waterfall, waves of ship ; in the first part of this thesis, we discuss the prevalent methods of the simulation of water scenes, in the second part of this thesis, we describe the numerical methods of solving the shallow water equations using the finite difference method and the finite volume method respectively, in the third part of this thesis, we simulate some realistically liquid phenomena such as rain droplets, the waves of ship, dam breaking etc
產生水波首先要有波源，設置不同的波源便可以得到不同的水流情形，我們用兩種方法來產生波源：一種是通過設置邊界條件和初始條件產生，這種方法用於模擬潰壩波的反射、折射等現象；另一種是通過擾動控制產生，這種方法用於模擬雨滴、瀑布、船波等自然現象。本論文的第一部分我們討論了目前水動畫模擬常用的幾種方法；在第二部分討論了我們所使用的兩類數值方法：有限差分方法和有限體積方法；在第三部分我們模擬了雨滴、船波、潰壩波等一些水流現象。 -
The highest level of a waterfall life cycle model is an example with its phases of : requirements, design, code, and test
最高層次的瀑布生命周期模型及其階段劃分是一個例子：需求，設計，編碼和測試。 -
Picture that put forward in the article graph and data structure reciprocal mapping support not merely to map graph from data structure efficiently, besides, regard graphics element as a unit, analyze and discern to user ' s modified graph, produce the corresponding data structure automatically, maintain consistency of graph and data structure efficiently on the foundation of expanding case graphic tools effectively, we direct against the intrinsic characteristic of traditional waterfall model, proposesmall loop model to software analysis based on graph and data structure reciprocal mapping solve problems of slow information feedbackand high track back cost efficiently
文中提出的圖數互逆映射的思想，不僅對數據結構到圖形映射進行高效率地支持，同時，以圖形元素為單位，對用戶修改後的圖形進行分析和識別，自動生成相應的數據結構，有效地維護了圖數一致性。在對case圖形化工具進行有效擴展的基礎上，我們針對傳統瀑布開發模型的固有特點，提出了基於圖數互逆映射的軟體分析小循環模型，有效解決了傳統軟體分析設計階段信息反饋慢、回溯代價高等問題。
