The major findings include:(1) By using fuel as the base indicator of relative efficiency, we found the following input factors' distribution inefficiency for domestic airlines: The distribution inefficiency of labor and capital input factors differs from airline to airline, and is becoming more severe with time; the distribution inefficiency of other factors does not differ very much among airlines but varies with time. It is inefficient from 1989 to 1995 but becomes more efficient during 1996 to 1997;(2) Airline companies have higher economies of density before 1996, but tend to show a constant return to density in 1997 when considering allocative distortions. The technical efficiency of input factors as a whole has declined after the open-air policy;(3) The costs of airlines are increasing significantly due to their distribution inefficiencies;(4) The instrument variable generated through a quasi price function does not have significant influence on cost; this may imply that airline companies in this time period did not exhibit the phenomena of high-quality high-price.
其主要结论如下:(1)藉由相对燃油分配效率探讨各投入要素之分配扭曲情形发现:劳动和因定投入要素之分配无效率因公司别而有所不同,且随时间而严重,唯民国86年稍有改善;其他要素之分配无效率则较不因公司别而有所不同,但亦随时间发生变化,初期为无效率,在民国85、86年则较具效率;(2)若考虑分配扭曲情形下,国内航空业在民国85年之前具有较高之密度经济,民国86年则趋向固定密度报酬;此整体投入要素之技术效率而官,在天空开放政策后其技术效率随时间变化而下降,但就燃油投入要素平均技术进步率而言,则其技术效率逐年增加且幅度明显;(3)航空公司因分配无效率所造成成本增加的情形相当明显;(4)准价格工具变数对成本之影响并不明显,此可能反映在此期间国内航空公司似乎并未趋向於高品质高价格之现象。

I have calculated the species diversity for 3 layers (i.e. tree layer, shrub layer and herb layer) by means of various biodiversity index formulas and analyzed the relative species abundance using 9 models of the probability density distribution functions, such as, 3 Distribution (or Beta Distribution, Weibull Distribution, Lognormal Distribution, Poisson Distribution, Binomial Distribution, Negative Binomial Distribution ,Geometric Distribution, etc.. chi-square analyses were conducted on species distribution by using the chi-square test formulated by Pearson to test which distribution function is better, the result of chi square test made it possible to reject the other 8 distribution functions, theβdistribution function performs better than other probability density functions, it has a very close approximation, which can be used for the description of relative abundances of species in forest communities in this data set.
在相对多度研究上选用了九种概率分布模型,这九种概率密度分布函数依次为:贝塔分布、Weibull分布、对数正态分布、泊松分布、二项分布、负二项分布、几何分布、对数分布和奈曼A型分布,并进行了严格的卡方检验,结果表明:其它八种分布均被遭到拒绝,只有贝塔分布获得了通过,且拟合的结果非常理想。

The LUMO electron density geometry distribution of N-TPA1 is located on the cyanoacrylic group which favour electron injection,but for N-TPA2 it is mainly concentrated on the rhodanine framework,and resulting in the position of LUMO isolated from the -COOH anchoring group due to the presence of the -CH_2- group.
由于罗丹宁乙酸基团的羰基与五元环构架间隔一个亚甲基,使得LUMO电子分布距离吸附基团远,阻碍电子经由羰基注入TiO_2导带,这是N-TPA2的敏化电池效率比N-TPA1低的原因之一。

An assumed Gaussian tail is addedonto the HO distribution. The calculations for〓 of the protron-rich isotones 〓〓 and 〓 and for 〓 the neutron-rich isotopes 〓were finished by theGlauber Model along with the modified density distrution. The calculated resultsshow that d values of these nuclei along with the modified density distribution arelower than the calculated ones along with the only HO density distribution.
