If scientists shine a single particle of light on a screen, the particle does something strange: It shows up in two places at once.

如果科学家将单个的光粒子投影在屏幕上，光粒子有奇怪的反应：它会同时在两个地方显像。

Ragno agrees with what Ferruccio Laviani maintains; that is to say, that the time is right and that, just as in the past we have witnessed the cyclical alternation of the use of woods, marbles, plastics, resins and stone for floors and, on the walls, of tapestries, woodwork, cloth, polished and matt paints, today the world of furnishing should be struck by a new creative wave that rediscovers the expressive and functional potential of ceramics.

蜘蛛同意FERRUCCIO LAVIANI 所坚持的，时间是适当的，就像过去我们看到的用木头，大理石，塑料，树脂和石头来铺地板；用挂毯，木刻，织布，抛光漆以及无光漆来装饰墙面。今天，世界装饰界将以瓷砖丰富以及功能性的潜力引领一种新的创新浪潮。

In order to reduce sideband spectral energy and improve image lining of a quartz filter,a novel filter structure was designed and its characteristics were analyzed theoretically.

为了改善滤波光谱的次极大，提高透过滤波片观察像的衬度，设计了减小次极大光强的石英晶体旋光滤波结构，并从理论上分析了滤波特性。

5500 Will also feature a LED backlight with local dimming, which means that LEDs are located behind the LCD panel and can be controlled in a number of zones, just like on thePhilips LED Lux model.

5500 也会特徵 LED 背光与本地调光指 LED 位於后面液晶显示面板，并可控制在多个区域，就像对 thePhilips LED Lux 模型。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
