Function definitions may not be nested but variables may be declared in a block - structured fashion 函數(shù)定義可以不在嵌套結構中,但是變量可以通過結構塊函數(shù)聲明
In the contrivance of the control system , block - structure is used and divided into two main types : public block and system block 模型開發(fā)時使用模塊化結構,分為公用模塊和系統(tǒng)模塊兩大類。
Synchronization also requires that locks be released in the same stack frame in which they were acquired , which most of the time is the right thing and interacts nicely with exception handling , but a small number of cases exist where non - block - structured locking can be a big win . the lock 同步還要求鎖的釋放只能在與獲得鎖所在的堆棧幀相同的堆棧幀中進行,多數(shù)情況下,這沒問題(而且與異常處理交互得很好) ,但是,確實存在一些非塊結構的鎖定更合適的情況。
A multi - block incompressible viscous flow solver has been developed that can be applied to simulation of a variety of ship maneuvering related flows and calculation of hydrodynamic forces . validation and verification of the solution procedure are carried out on several model problems with good agreement to experimental and numerical results . the present block - structured viscous flow solver is based on solving the reynolds - averaged navier - stokes ( rans ) equations with a second - order cell - centered finite volume method ( fvm ) on non - staggered grids 本文即在這種背景下,瞄準船舶操縱水動力預報方面的國際前沿和熱點課題,通過對現(xiàn)代船舶粘性流計算方法的研究,自主開發(fā)了一個船舶操縱粘性流求解器,并將所開發(fā)的求解器成功地應用于一系列和船舶操縱問題相關的粘性流動與水動力計算,得到了令人滿意的結果。
These characteristics therefore , make it have wide application prospect . as a part of the crt simulator control system of a dcs power plant , this paper constructs the model of the real control section by using block - structure method and finishes the contrivance of the coordinated control system ( ccs ) , the digital electro - hydraulic control . system ( deh ) and the control system of boiler and turbine 作為開發(fā)基于dcs的火電廠全crt仿真機的一部分,本文采用結構化、模塊化的方法,對實際控制環(huán)節(jié)進行建模,完成了仿真機中的協(xié)調控制系統(tǒng)和功頻電液控制系統(tǒng)以及鍋爐、汽輪機控制系統(tǒng)模型的開發(fā)。
According to the structure characteristic of the chamber and the flow characteristic , the author uses two approaches : one is an approach of rotating the mesh system to divide the area of burning ; the other is an approach of the block - structured grid method and the adaptive grid technology to divide the mesh and refine the grid 本文作者根據上下爐膛的結構特點和流動特點,采用了將網格系統(tǒng)扭轉一定角度的方法來對燃燒器區(qū)域進行網格劃分,并采用塊結構化網格方法和網格自適應技術來實現(xiàn)整個爐膛的網格劃分和加密。
