Death is never a horrible thing,just how you will die matters,everyone in the end will be dust,noblers,niderings,no matter how you are bound to end up in dust," for out of it wast thou taken,for dust thou art,and unto dust shalt thou return" But to die without one's duty fufilled is also one of the biggest shame of man-kind.you must have noticed the background music of this passage-----the theme music of the film Letters from Iwo Jima,a film makes every Chinese feel complicated.whether this film beautifies Japanese Imperial Army or not is not what I want to discuss here.

死亡从来都不是一件可怕的事情，我们只需要在乎怎样死去，每一个人都会在尘土中了结他的一生。&因为你从尘土中来，你既然是尘土，就要回到土中去&《创世纪》。但是抛弃责任而死去，也是人生的一大耻辱。大家一定注意到了这篇文章的背景音乐---电影《硫磺岛家书》的主题曲。这是一个让每一个中国人感到心情复杂的作品。关于这部电影是否美化了二战中的日本军队，我在这里不想作任何评论。

In the National Natural Science Fund Project, supported by the Institute through 10 years in a row on the lake dried up Ebinur region of proliferation and the accumulation of observations and sampling analysis found that,Lop Nur, the Ebinur Lake, Xinjiang艾丁湖region is the main source of salt dust, from the bottom of the lake dried up Ebinur region of dust is an important source of salt dust material, Salt in the region of the frequency of dust storms has created extremely favorable conditions.

据中科院新疆生态与地理研究所吉力力阿不都外力研究员介绍，在国家自然科学基金项目支持下，该所通过连续10年对艾比湖地区干涸湖底的扩散和堆积进行观测和取样分析发现，罗布泊、艾比湖、艾丁湖地区是新疆盐尘暴的主要策源地，源自艾比湖地区干涸湖底的粉尘是重要的盐尘暴物质来源，为该地区盐尘暴的频发创造了极为有利的条件。

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。

Based on data from the dust storm monitoring station over Hunshandake Desert Area, Inner Mongolia, the maximum values of micrometeorological variables, turbulent fluxes and dust concentration in the surface layer are compared for eight dust events in the spring of 2004, and the characteristics of micrometeorology and radiation components in the strongest dust storm event in March 27-28 are analyzed.

利用内蒙古浑善达克沙地沙尘暴实验探测资料，给出2004年春季多次沙尘天气过程近地面微气象学要素、湍流通量及沙尘浓度的极值对比，重点分析了3月27-28日强沙尘暴过境时近地面微气象学要素和辐射分量的变化特征。
