因此，确定研制方案的重要工作之一就是从全寿命费用的角度出发，在采购费与维修费之间进行权衡[1]，确定最佳的维修费用水平，以确保有限资源的有效利用。

Host controller and multiple-site controller using asynchronous serial communication, or "soft-serial" in accordance with the "communication protocols" to achieve branch communications, computer controlled multi-component of "Distributed Control" system, according to three Flop flip side of the control sub-drive motor, to achieve large-scale three sides of the sign face will be over the screen, time, optional flip way, the sign face of an error "automatic error correction flip" and drive the requirements.

主控制器和多个现场控制器之间采用异步串口通信或"软串口"按照"通信协议"实现分支通信，组成多微机联控的"集散式控制"系统。这种多微机联控系统极大地简化了控制电路的连线，简化了电气控制安装工艺与施工，在降低工程费用和后期维修费用的同时，可大幅提高控制系统工程的可靠性、稳定性、性价比。

Earlier the church authorities put the cost of repairing its neo-Gothic facade at 3.5 million euros (US$5.1 million), but now due to continuing disintegration the cost has soared to 4.1 million euros.

早些时候，教堂当局估计修缮新哥德式外观费用大概是350万欧元（510万美金），但是现在由于墙体不断的损坏，维修费用已经增至410万欧元。

The mathematical model of complex countercurrent multi-effect evaporation with condensed water flash is established, which aims at minimum annual cost (including cost of fresh vapor, vacuum pump power, evaporator, maintenance and depreciation).Based on such decisive variables as the pressure of fresh vapor, the pressure of condenser and heat-transfer mean temperature difference of vari-effect,the model is solved by the complex method,Lagrangian multiplier method, iteration method and matrix method.The practical example indicates that the influence of the pressure of fresh vapor, the pressure of condenser and flash of condensed water on the optimum design results is notable.

建立了带有冷凝水闪蒸的复杂逆流多效蒸发系统优化设计的数学模型，该模型以整个蒸发系统的年总费用(包括加热蒸汽年费用、真空泵年动力费用以及蒸发器和辅助设备的年折旧维修费用等)最小为优化目标，以生蒸汽压力、冷凝器真空度及各效有效传热温度差为决策变量，提出一种新算法———复合形法结合Lagrangian乘子法、迭代法和矩阵法求解模型。
