Aiming at the function and performance limitations of traditional special cnc or current pc - based open - structure cnc, a brand - new cnc platform designing scheme of multi - layer open - architecture is presented, based on embedded - mcu calculation and management core, and three kinds of expanding mode of software, hardware and interface. by using double system working ram and boot rom technology, an independent re - development interface is set on the hardware platform to realize customized function ’ s simulations and verifications online, which makes all the expanding or re - configuring on basic cnc platform are all safe and restorable
本文針對傳統專用數控系統的結構封閉、交互形式不通用和配置擴展不靈活方面的劣勢以及當前pc模式開放結構數控的體積龐大、開放程度不高和實時可靠性不強的局限，創新性地提出了以基本cnc框架+軟體、硬體和介面三種擴展形式為特徵的層次化開放結構的嵌入式cnc硬體平臺，並採用雙存儲區技術進行了cnc系統在線模擬校驗機制和安全保護機制的方案設計。 -
After a comprehensive review on the study of sediment density current in the recent several decades, a set of differential equations for 2 - d density current under double - layer computational mode is established. by simplifying th. set of equations, a 2 - d numerical simulation of sediment density current and sediment outflow has been made in the liujiaxia reservoir in the yellow river basin, and the result is reasonable
本論文在對異重流運動近幾十年來的研究成果進行較系統、全面論述的基礎上，針對目前研究較為前沿的異重流運動數值模擬問題，提出了一套二維異重流雙層計算模式下的基本方程，並在這套方程簡化的基礎上，對黃河流域劉家峽水庫中的異重流運動和排沙進行了二維數值模擬，結果令人較為滿意。 -
This paper first presents the uncertainty of water resources and the process of fuzzy set theory in this field, then analyzes the current conditions of agricultural water resources and its sustainable developments in our country. based on the researches in this field, considering its character of multi - objective, multi - layer, multi - function and multistage, this paper mainly deals with the fuzziness and stochastic uncertainty of agricultural water resources system. the major contents and research results are as follows : 1 based on chen shouyu ' s fuzzy set theory, this paper presents a fuzzy optimal multi - dimension and multi - objective dynamic programming model, then two methods are given
本文首先闡述了水文水資源的不確定性及模糊水文水資源學的發展現狀，分析了我國農業水資源現狀及其可持續利用，在論述區域農業水資源優化領域研究現狀的基礎上，鑒于農業水資源系統優化的多目標、多層次、多功能、多階段、多維與隨機的特徵，針對系統中普遍存在的模糊性和隨機性開展研究，主要研究內容和研究成果概括如下： 1 、基於陳守煜提出的多目標模糊優選動態規劃理論，提出復雜水資源系統的多維多目標模糊優選動態規劃問題的兩種求解辦法：多維多目標的決策序列相對優屬度總和最大法和多維多目標階段模糊優選動態規劃方法。
