浮尘

City streets are blanketed in red wrappers, and the air is thick and acrid with dynamite dust.

红红的鞭炮屑铺满了城市的街道，空气中弥漫着火药燃烧后的浮尘。

Sandstorms hit north China during the weekend, blanketing many cities in floating dust.

上周末，沙尘暴袭击了中国的北方，并有许多城市笼罩在浮尘中。

Use steel brush or burnisher to clean dust and weathered layer on the surface of concrete

用刚刷或角磨机去除混凝土表面的浮尘和风化层

The dust devil and fly ash which happened from Tarim Basin to the west of Hexi Corridor on May 13~14th in 1999 is analyzed with the data from FY-1C meteorological satellite launched recently in China.

利用我国新近发射的风云-1C极轨气象卫星，对1999年5月13～14日发生在塔里木盆地至河西走廊西部的沙尘暴与浮尘扬沙天气进行分析。

It showed that this course of dust devil just occurred at the south of the basin and moved eastwards along the north of the Kunlun Mountain and Altun Mountain, then the dust devil influenced DunHuang region nearby and weakened as fly ash.

发现本次沙尘暴过程仅发生在盆地南部并沿昆仑山、阿尔金山等山脉北麓向偏东方向移动，然后影响到敦煌附近并逐渐减弱为浮尘扬沙天气。

The results illustrate that the dustfall in Hotan is influenced by days and intensities of airborne dirt,raising sand and sand storm and has important effect on the soil.

通过野外调查、定位试验和室内分析，探索了新疆和田扬沙、沙尘暴、大风和浮尘产生的原因及发生规律与土壤降尘量的关系及其时空变化特点。

A great deal of thin sand in the weak convergence zone went to Lhasa along with the western high-level air current.

最后，给出了拉萨浮尘天气预报的思路，为拉萨浮尘天气的准确预报提供了一些参考信息。

Floating dust is the mildest form of sandstorms, and Beijing would not be much affected.

浮尘是沙尘暴的中度表现形式，此次浮尘天气的到来不会给北京带来很大的影响。

By using global reanalysis data from NCEP/NCAR,the durative of a floating dust over Beijing during 7-10 in April of 2006 was analyzed.It was found that the impact systems of the floating dust weather were West Siberia cold eddy,Okhotsk warm high and Tibetan Plateau high ridge at the level of 500 hPa;the dry-cold air at the level of 700 hPa transferred to Beijing ceaselessly,and the cold advection and baroclinic instability were strong,the gale and dust storm occurred in the strong cold advection area;the weak instability stratification in surface layer and mid-low level in the south of North China resulted in weak ascending air flow,then transported dust particles to Beijing depending on the easterly wind in front of the surface low pressure.

文章摘要：使用NCEP/NCAR再分析资料对2006年4月7-11日北京浮尘天气过程的持续性进行分析，指出此次浮尘天气过程主要受500 hPa西西伯利亚冷涡、鄂霍次克海暖高压以及青藏高原高压脊影响；700 hPa有干冷空气不断向北京地区输送，冷平流和斜压性都很强，大风和沙尘暴发生在强冷平流区域；由于华北南部地区近地面至中低层存在弱的不稳定层结，容易产生弱的上升运动。

According to the observation of the number concentration spectrum and the mass concentration of atmospheric aerosol, TSP and its particle size distribution,micrometeorology,and the solar spectroscopic radiation,even the neutron activation treatment of sand dust samples in Helan Mountainous area, the formation law of sandstrom, dust and sand blowing weather and the characteristics of climatic variation in this area and the influence of Helan Mountain are counted and analysed.

利用贺兰山地区沙尘暴历史资料和综合观测资料，对大气背景、浮尘、扬沙和沙尘暴发生期间的大气气溶胶数浓度谱、质量谱、大气总悬浮颗粒及粒径分布、微气象、分光日射观测以及沙尘样品进行中子活化处理，分析了该地区浮尘、扬沙和沙尘暴形成规律，气候变化特征和贺兰山的影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
