Yongding Qu Xiang liquidamber three rural Museum and co-operation in the territory Xiang has 12 indigenous construction lime kiln did not apply for any formalities illegal immigrant without a license belonging to the illegal production and operation, the simple process, there is no dust removal, desulphurization, and other environmental protection facilities in Sulfur dioxide emission of 100 tons and a large amount of dust and seriously pollute the environment, destruction of national resources, harm the interests of the masses, there is a big security risk, it is national policy explicitly out backward production capacity.

永定区枫香岗乡、三家馆乡和合作桥乡境内有12座建筑土法石灰窑未办理任何手续，属于无证无照非法生产经营，其工艺简单，没有除尘、脱硫等环保设施，年排放二氧化硫达100吨以上，并产生大量粉尘，严重污染环境，破坏国家资源，损害群众利益，存在极大的安全隐患，是国家政策明令淘汰的落后生产能力。

This showed that capacity of water-holding in biological soil crusts were obvious improve,and effected precipitation permeate or water second distribute process.The study results of"fertile islands"formation mechanism in biological crusts showed that biological crusts layer cover could increased nutrients content for below sand soil through precipitation permeate washing,and it promoted plants assimilate more nutriment.The matter import ways of biological soil crusts fertility island had many ways,including the effection of living macrobiotics metabolism in crusts levels,wind-sand flow of near surface,dust deposition and plants decomposition course,etc.Source of particle matter in biological soil crusts was wind-sand flow of near surface,and not dust deposition.Biological crusts layer cover had preserved effection for nature water content in 0-5cm soil layer,compared with the sand of no biological crusts layer,effecting precipitation permeate,and could not obvious restrained from the water evaporate process indoor experiment.

生物结皮层肥岛形成机制的研究结果表明：生物结皮层覆盖能够通过降水淋溶作用而增加下层土壤养分的含量，进而促进植物对养分的吸收；生物结皮层养分输入有结皮生物代谢、降尘、风沙流和植物分解矿化作用等多(来源：A73e3B3eC论文网www.abclunwen.com)种途径，但生物结皮层的颗粒物质来源主要是近地表风沙流，而不是大气降尘；生物结皮层覆盖对0-5cm土层自然含水量有一定的保护作用，并影响降水向深层渗透，不能有效的阻止表层水分的蒸发进程；研究表明采取人工促进技术能够在流动沙丘上形成生物结皮层，实现流动沙地的快速治理。

As a result, parts of the dust cloud have become stratified, pointing toward Merope. The closest particles are the most massive and the least affected by the radiation pressure. A longer-term result will be the general destruction of the dust by the energetic starlight.

因此，部份尘埃云形成指向昴宿五的层状结构，最靠近昴宿五的尘埃粒质量也最大，因为它们受到辐射压的影响最小，更长期的效应是尘埃微粒会被高能量星光给全部破坏。

I should like, however, that my dust should mingle with kindred dust.

我喜欢，不过，我的尘土与骨肉灰尘混在一起。

The mudsill and bracket of RWD/QX--48 X1X 2 electrical dust precipitator act as the primary study subject in this paper, and finite element analysis and optimization analysis are made by use of large-scale finite element analysis software I-DEAS, aiming at the demerit of nonstandard design on electrical dust precipitator in our country.

中文摘要：本论文主要以RWD/QX—48×1×2型电除尘器的底梁和支架为研究对象，针对我国电除尘器生产单位对其设计不规范、结构不合理的缺点，利用大型通用有限元分析软件I-DEAS对其进行了有限元分析和优化计算。

It was found that the pemeability of the dust core was almost a constant in the frequency range from 1KHz to 100KHz,and the quality factor Q of dust core increased with increasing frequency.It was also found that Q became higher at the frequency over 50KHz in comparison with that of permalloy in higher frequency.

结果表明，在测量的频率范围内(1KHz-100KHz)，该粉芯的磁导率几乎不随频率变化而变化；粉芯的品质因数Q随频率的增加而增加，在较高频率时有着比坡莫合金粉芯还要高的值，具有应用价值。
