Specifications are written using UML+, they are automatically verified by means of formal methods, and are then converted  through a semiautomatic process  in an equivalent UMLRT model that becomes the starting point for the implementation.


Measured clearsky values of jHONO were compared with values calculated by a fourstream discrete ordinate radiative transfer (RT) model (ACD TUV version 4.1), and were found to be within better than 10% agreement for solar zenith angles >amp;lt; 65°.


The parameter α of the RT model is found to depend on n, whereas the parameter q of the Gursontype models does not vary with n.


Both the dynamic HPF Smagorinsky model and the dynamic RT model are showing good predictions.


Especially the dynamic HPF Smagorin sky and the dynamic RT model gave very satisfying results.

 On the basis of subsidence data calculated on over twohundred artificial wells in the Huanghua rift , the authors of this paper got two kinds of subsidence curves. The ratio of the thermal subsidence to the initial subsidence is also calcuiated. In comparison with the previous geo  dynamical models of the continental lithosphere extension , ours is more similar to the simple shear model. So it is proved that the rifting in Huanghua basin accommodated under the simple shear pattern, which is different from...

So it is proved that the rifting in Huanghua basin accommodated under the simple shear pattern, which is different from the North Sea extensional basin formed by pureshear model.  在计算覆盖整个黄晔裂谷２００口人工井（包括少部分探井）沉降量的基础上，总结本区二种基本沉降曲线模式。统计出热沉降（Ｓｔ）与初始沉降（Ｓｉ）之比为０．６，依此为约束条件与大陆岩石圈伸展的地球动力学正演模式进行对比，与简单剪切模式预测的热沉降与初始沉降之比值及几何效应更接近。进一步证实黄骅裂谷以简单剪切机制形成的地球动力学模式更合理，这与著名的以纯剪模式形成的北海伸展盆地不同  The knowledge of the absorption coefficients of ozone in the UV band is of major importance for the monitoring of the atmospheric ozone layer using the solar backscattering ultraviolet technique.In order to gain significant measurements of atmospheric ozone,accurate ozone absorption coefficients should be derived from the high accurate laboratory measurements of absorption crosssection of ozone.To make sure the absorption coefficients are be precise,it was checked and validated the now existing ozone coefficients... The knowledge of the absorption coefficients of ozone in the UV band is of major importance for the monitoring of the atmospheric ozone layer using the solar backscattering ultraviolet technique.In order to gain significant measurements of atmospheric ozone,accurate ozone absorption coefficients should be derived from the high accurate laboratory measurements of absorption crosssection of ozone.To make sure the absorption coefficients are be precise,it was checked and validated the now existing ozone coefficients bank in the American TOMRAD model using these high accurate and high resolution laboratory measurements data published in the international journals in the past few years.From 1980s,many papers on laboratory absorption cross of ozone measurement data with different spectrum resolution and measurement accuracy were published in all kinds of international journals.Among these,data from French Brion,et al.have much more higher spectrum resolution and measurement accuracy than others.First,some wavelengths were radnomly selected from Hartley and Huggins band respectively.For every wavelength,the regression model of the ozone absorption crosssection to temperature was built with the widely used polynomial formulas and the ozone absorption coefficients for these wavelengths were obtained.To check the now existing ozone absorption coefficients,the calculated coefficients were compared with that from the American TOMRAD model coefficient bank.Second,to validate the coefficients of the TOMRAD model,at these randomly selected wavelengths,the ozone absorption crosssection under the same temperature were calculated with that of Ozone UV Spectroscopy II Absorption crosssections and temperature dependence,and the calculated data were compared with the laboratory measurement data in Ozone UV Spectroscopy II Absorption crosssections and temperature dependence.The results show that the calculated crosssection at Hartley band using coefficients from the TOMRAD model is quite consistent with that laboratory measurement from Ozone UV Spectroscopy II Absorption crosssections and temperature dependence,the variance at most randomly selected wavelengths is smaller than 3%.However,in the Huggins band,the variance at most wavelengths is much more bigger, at some wavelengths,the variance is bigger than 50%.Since,data from Ozone UV Spectroscopy II Absorption crosssections and temperature dependence have higher spectrum resolution and accurate than that data by Bass and Paur,from which the now existing ozone absorption coefficients were drawn.It is reasons to suspect the validity of the now existing ozone absorption coefficients at some wavelength in Huggins band.  利用国际权威期刊上发表的臭氧吸收截面观测数据,检验和验证了现有的紫外正演模式TOMRAD臭氧吸收参数数据库。结果表明,在Hartley臭氧吸收带上,观测数据与数据库参数吻合状况很好;而在Huggins臭氧吸收带上,观测数据与数据库参数在部分波长上存在较大偏差,某些波长上的偏差超过50%。鉴于此,FY3紫外臭氧探测仪资料处理计算中,选取臭氧吸收参数,必须特别慎重。
