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。

To increase the performance of the SuperVeloce, the intake system was modified, the valve train optimized and, most importantly, valve travel was increased.

所有给SV增加的动力，进气系统会随着相应总状态进行适时调整最佳化的气阀结构，最重要的是，阀动行程也会相应的增加。

"Sri Lanka" ship is powered by 2 General Electric A4W/A1G the pressurized water reactor and steam turbine 4, the reactor thermal efficiency of 25.6 percent for each reactor 2 steam turbine-driven, with a total power of up to 260,000 horsepower, The maximum speed of 30, the sustainable use of fuel for 15 years, range up to 800,000 -100 10,000 sea miles, self-sustaining force for 90 days.

&斯&舰动力装置为2座通用电气公司的A4W/A1G压水堆和4台蒸汽轮机，反应堆热效率为25.6%，每个反应堆驱动2台蒸汽轮机，总功率高达26万马力，最高航速30节，燃料可持续使用15年，续航力可达80万－100万海里，自持力为90天。

According to self-estimate, appropriately lengthening the time of education for 15- 19 year-olds to halve the 6.37% proportion of employment to the national total, we shall be able to cut the nationwide jobs by 23 million, of which 5 million were jobs in cities and towns. This would not only alleviate the pressure of employment, but also raise the cultural quality of the youngsters and rear high-quality human resources, providing motive force and fountains for the sustainable development strategy of our country.

据测自，适当延长15-19岁青少年受教育时间，使其就业人数占全国总就业人口比重由目前的6.37%下降一倍，那么全国劳动就业供给量可望减少2300万人，其中城镇可减少500万人，这样不仅可缓解就业压力，还可大大提高青少年的文化素质，形成高质量的人力资本，为我国的可持续发展战略提供动力和源泉。

In the film, with the South American accent, impaired intellectual Forrest Gump looked full of Jenny's wild, as if the United States and the master of Faulkner's famous novel,"Sound and the Fury" in Bangui is a distant relative of the fool.

有趣的是，阿甘身后总有一群尾随者，他们找不到人生的答案，盲目地追随阿甘，可以这么说，这就是美国当时社会的一种现实，人们对现实失望，找不到生存的动力与意义，只好无望地把命运寄托在别人身上。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
