On the other hand, through the discussion on coronal density of flares, we found that the column mass density at the top of chromospheric flare model can not be represented the total mass above the chromosphere and the coronal density can be estimated from presure balance based on semiempirical model. Through estimations, the results show that the total mass above the chromosphere is about the same as the mass between the top of chromosphere and electron source, which so give an evidence that the source of electrons is situated at the top of flare loop.

另一方面，通过对日冕物质密度的讨论发现，半经验模型中色球顶部柱数密度不能用来代表耀斑环在日冕内的总物质，日冕物质密度可用日冕气压与半经验模型中色球顶部压力近似相等来进行估计，进而发现耀斑环在日冕内的总物质与前面估计的色球顶部到非热电子源之间的总物质近似相等，结果趋向于支持非热电子源位于环的顶部。

Priority PAHs recommended by USEPA were all detected, and the mass concentrations of individual PAHs was between 1.49 and 87.43ngg^(-1), The PAHs with low molecular weight, such as Nap, Flu, Ace were observed in relatively low mass concentrations. The PAHs with high molecular weight, such as Chrysene, Indeno [1, 2, 3-cd] pyrene, Benzo perylene were relatively abundant and the mass congcentration of BghiP was the highest. The total mass congcentration of 16 PAHs exceeded standard of Holand from 10 to 40 times, and in middle pollution level comparatively with other districts.

When the amount of SO(superscript 2- subscript 4)/ZrO2 catalyst was 7% of the mass of β-pinene, the yield of product was 62.0%, and the mass ratio of borneol to isoborneol in the product was 13.6:48.7. When the amount of S2O(superscript 2- subscript 8)/ZrO2 catalyst was 7% of the mass of β-pinene, the yield of product was 66.7%, the mass ratio of borneol to isoborneol in the product was 11.5:49.5. Both two catalysts were poor for borneol selectivity.

在上述反应条件下，当催化剂SO(上标 2-下标 4)/ZrO2用量为7%时（以β-蒎烯质量计，下同），粗龙脑产率为62.0%，产品中正、异龙脑比为13.6：48.7；当催化剂S2O(上标 2-下标 8)/ZrO2用量为7%时，粗龙脑产率为66.7%，正、异龙脑比为11.5：49.5；这两种催化剂对正龙脑选择性比较差。

There is a mass noted over the posterior cervical space in the left posterior neck ,that corresponds to the mass palpated by patient.This mass appears hyperintense on T2 image,and shows moderate contrast enhancement.Radiograph confirmed the presence of a phlebolith at this location,and complementary ultrasound shows hypoechoic mass which is compressible.

In 1959 Sauerbrey developed an empirical equation to describe the mass sensitivity of gas phase mass deposition on a piezoelectric quartz crystal——Sauerbrey equation:ΔF=〓=-CΔm, where ΔF is measured frequency shift, in Hz; F〓 is the fundamental resonant frequency, in Hz;Δm is mass change, in g; A is piezoelectrically active area , in cm〓;μ〓 is shear modulus of quartz, 2. 947×10〓g· cm〓;ρ〓 is density of quartz, 2. 648g·cm〓; C is mass sensitivity constant , in 〓.

1959年，Sauerbrey最先提出了将压电晶体谐振器用作定量测量质量的装置，并从理论上导出了频率与质量变化之间的关系式——Sauerbrey方程：ΔF=〓=-。。。

By non-enhancement scan, 12 cases showed low density mass, 4 cases equal density mass, 1 case slightly high density mass, and 2 cases stippled calcification mass. By enhancement scan, 13 cases showed inhomogenous enhancement in cortical phase, 2 cases showed slight to moderate enhancement. Another 2 cases of small cystic RCC presented enhancement of wall with nodules and the partition. The enhancement of all tumor cases faded away in the following parenchymal phase and pyelographic phase, demonstrating some degrees of "fast washing out" phenomenon; 4 cases presented with pseudocapsule. The reconstruction of 17 "MPR/MIP" and 9 "VR" showed clearly the relations of kidney vessels, tumors and neighbor tissues and accessory renal arteries were founded in 2 cases.

Driven by commercial interests, mass media has, by utilizing its right to speech in public domains, mythicized football, a widely influential mass cultural form, and turned football into the main body of mass media for spreading sports information, which has resulted in the deprivation of the right of sports audience to enjoy multi-element sports information, and the distortion of the sports communication behavior of mass media under the guidance of commercial logic, and has done a certain degree of harm to the healthy development of the sports un-dertaking.

摘 要：大众媒介在商业利益的驱动下利用其在公共领域内的话语权，将足球这一影响广泛的大众文化形式神话化，使其成为大众媒介体育信息传播的主体，导致体育受众享受多元体育信息的权利被剥夺，同时也使得大众媒介的体育传播行为在商业逻辑的主导下发生了畸变，给体育事业的健康发展造成了一定程度的危害
