超視粒 的英文怎麼說
中文拼音 [chāoshìlì]
超視粒
英文
amicrone-
For example, the eu allows the hourly average sulphur dioxide standard to be exceeded 24 times a year ( whereas hong kong allows only three times ). the eu also allows the daily average respirable suspended particulates standard to be exceeded by 35 days in a year ( whereas in hong kong it would be considered falling short of the aqo if exceeded by more than one day ). having more allowable exceedances, the eu standards thus have numerical values significantly lower than those of hong kong
例如歐盟的標準容許二氧化硫的一小時平均值在一年內可超過其限值二十四次， （香港空氣質素指標只容許超過限值三次） ；亦容許可吸入懸浮粒子在一年內超過其日均限值三十五天才視為超標， （香港只超過空氣質素指標的限值多於一日便視為超標） 。In the first part, the basic knowledge of particle scattering in meteorology and physics was introduced. the particles to be discussed include aerosol particles, fog droplets and raindrops and the em wave band in the discussion is near - infrared. in the second part, the mie theory was briefly reviewed and was applied to investigate the scattering characteristics of spherical atmospheric particles, the result shows that in the visibility measurement meter using forward - scattering method, when the working wavelegth is between 0. 8 m ~ 2 m, the scattering angle is between 25 ~ 40, the distinguishability and the relative scattering intensity would be better than those under other conditions. in the third part, the superellipsoid was used to describe a wide range of shapes such as spheres. ellipsoids and cylinders. an improved t - matrix method which can be used to calculate arbitry shaped particle ' s scattering field was introduced, and the scattering characteristics of non - spherical atmospheric particles was investigated with this method
計算結果表明，從相對散射強度、同一方向上不同粒子散射的可區分程度來看，在散射式能見度探測儀器中，工作波長介於0 . 86 m 2 m ，探測角度選取前向25度40度時，探測的結果將會是比較理想的。第三部分中，使用超橢球方程來統一描述各種非球形粒子的形狀，然後使用t矩陣方法計算了一些形狀的非球形粒子的近紅外散射特性。另外，在本文中還針對球形粒子的散射場提供了一種三維可視化方法，使對散射場強度的空間分佈的理解更加簡單，直觀。Viewing solely from their performance, mdf, dsp, rpc all enjoy a high compressive strength. their flexural strength, fracture toughness and elastic module have broken the limit of traditional cement based materials. all these materials have acquired the features of high toughness material
從材料性能審視，無宏觀缺陷水泥基材料、均布超細顆粒緻密體系、活性粉末混凝土等的抗壓強度都非常之高，其抗拉強度、斷裂韌性和彈性模量也突破了傳統水泥基材料的限度，這些材料具備了高強韌性材料的特徵。In the composite methods of superfine powder, mechano - chemistry is more and more popular and received by majority, because this method has a splendid prospect application
在超細粉體粒子的復合方法中，機械化學法由於具有良好的應用前景，越來越引起人們的高度重視。For rsp, the eu allows the daily average rsp standard to be exceeded 35 days in a year, whereas the relevant aqo of hong kong does not allow a single day of exceedance at all
在可吸入懸浮粒子方面，歐盟指標在一年內須超過其日均限值35天才視為超標；但香港只超過限值1天便視為超標。分享友人
