He says that Day gives us appearance And you just hide at night: Still fluttering Your wings extend into Night Flying and searching For Time that will return Through the cracks of horizon He says that Time has already returned Everything same as that of yesterday: Houses on empty streets Snow on roofs Silence on snow But you must lift the silence and throw it away Bringing everything Buried in the ruins of Time To the light of Day: Greed, robbery, slaughterer In that silently weeping city Who licks its incurable wound At night He says that we will open our eyes Walking through Time and its inventions: Look, silence thrown away, The flocks of pigeons Waving In the blue morning sky But now, you are walking at night Still searching Along the path of Time Yet, with a peaceful mind

他说，白天给予我们面容你遁影于夜晚：仍扇动着与夜相连的翅膀飞寻从地平线裂痕中归来的时间他说，时间已经归来一切就绪，犹如昨天：空街上的屋屋顶上的雪雪上的沉默但你必须掀开沉默将埋葬在时间废墟中的一切在白日的光里现形：贪婪，掠夺，屠杀在那座伤痕累累的城市：只在夜里舔摸自己永不愈合的伤口他说，我们将睁开眼睛穿行在时间与它的发明中：看，沉默掀去，白色的鸽群于清晨的蓝天中如波飞行而此时，你行走在夜色仍在追寻沿着时间的来径但，以一颗安宁的心

The dynamic light scattering is an effective method to measure grain diameter in nanon and submicron.

Although there are only several dozens of micron from 45 microns to submicron or nanometer, but if the diameter less than submicron, its surface area, optical character, electrical character, magnetical character, energetics character and surface feature will be changed. We could acquire transnormal effect, so that the price of material will increase with transnormal scale.

从45微米到亚微米、纳米虽然只有几十微米的差距，但由于物料粒径小到亚微米之后，其表面积、光、电、磁、热力学性质及表面特性均发生了奇特变化、使用时可获得超常效果、从而使物料的商品价值也以超常的比例递增。
