This high voltage electrostatic precipitation controller has 7 channels of analog input,2 channels of analog output, 12 digital inputs and 16 digital outputs. The analog input includes primary current, secondary current, primary voltage, secondary voltage, etc. Controller uses MAX 187 as the A/D converter, which ensure the sampling speed and the conversion precision in the same time. The processor unit is RCM2250 module. Rabit 2000 processor, a 128K SRAM and a 256K Flash Rom are integrated in RCM2250, which improves the performance of pricipitation controller. MAX504 is used to produce the 4~20mA current output.

模拟量输入采集的信号有升压变压器一次电流、一次电压、二次电流、二次电压等，采用12位逐次比较式A/D转换器MAX187，兼顾采样速率和转换精度；中央处理单元采用以8位嵌入式处理器Rabbit2000为基础的RCM2250模块，外扩128KSRAM和256K Flash ROM，内部资源丰富，提高了控制器的整体性能；模拟量输出采用内带基准源的10位电压输出数模转换器MAX504，实现了标准4～20mA电流信号输出；控制器通过控制算法在相应开关量点上输出可控硅的触发脉冲。

An industry spokesman said:"If biomass takes off, farmers could plant thousands of acres of land with energy crops such as willows and miscanthus, or elephant grass, a bamboo-type grass which would be harvested to fuel small power stations."

一位业界发言人说："如果生物质能被利用起来，那么农民就可以在数千英亩的土地上种植能源作物，如柳树、芒属植物或象草——一种类似竹子的草，可以用作小型发电厂的燃料。"

When I do count the clock that tells the time, And see the brave day sunk in hideous night, When I behold the violet past prime, And sable curls all silvered o'er with white: When lofty trees I see barren of leaves, Which erst from heat did canopy the herd And summer's green all girded up in sheaves Borne on the bier with white and bristly beard: Then of thy beauty do I question make That thou among the wastes of time must go, Since sweets and beauties do themselves forsake, And die as fast as they see others grow, And nothing 'gainst Time's scythe can make defence Save breed to brave him, when he takes thee hence.

当我数着壁上报时的自鸣钟，见明媚的白昼坠入狰狞的夜，当我凝望着紫罗兰老了春容，青丝的卷发遍洒着皑皑白雪；当我看见参天的树枝叶尽脱，它不久前曾荫蔽喘息的牛羊；夏天的青翠一束一束地就缚，带着坚挺的白须被升上殓床；于是我不禁为你的朱颜焦虑：终有天你要加入时光的废堆，既然美和芳菲都把自己抛弃，眼看着别人生长自己却枯萎；没什么抵挡得住时光的毒手，除了生育，当他来要把你拘走。

One or both of transmit and receive aperture controls may include preventing some element of the transducer array from transmitting or receiving, calculating weighting apodizations to combine with standard apodizations for each frame, or determining an aperture size based on an f-number for the transducer array for each frame.

发射和接收孔径控制中的一个或二者可以包括：阻止换能器阵列中的某个元件进行发射或接收，针对每一帧计算加权变迹以将其和标准变迹相组合，或者针对每一帧根据换能器阵列的F数来确定孔径尺寸。

Tracksites occur exclusively throughout several stratigraphic levels of a thick, mixed-affinity, lagoonal-terrestrial sequence known as the Upper Red Formation in north central Iran and within a continental series deposited in the southern Caspian area in north of the country. The tracks from the Upper Red Formation are mainly artiodactylan type, attributed to several gazelle sized species due to their small size, and other tracks attributed to small, medium and large sized mustelid and felid carnivores.

足迹化石在伊朗中北部分布在一套被称为上红组的厚层、混杂的泻湖－陆相地层序列的数个层位中；在伊朗北部的里海地区南部，则位于一套陆相沉积序列中：产自上红组的足迹以偶蹄动物类型为主，由于个体很小，可归入几种像羚羊一样大小的种；其他足迹则分别归人小型、中型和大型的触科和猫科食肉动物。

In this paper, a new approach for automatic extracting the local maximum lines from the first horizontal derivative images of geophysical fields is proposed.
