Secondly, we provide a two-level model to depict the one-, two-and three-photon fluorescent process and with it to calculate the one-, two-and three-photon fluorescence intensity dependence of the incident excitation intensity and time. We study the fluorescence intensity when excitation light's time distribution are square pulse、Gaussian pulse and sech pulse. We find that the influence of excitation light's time distribution on the two- and three- photon fluorescence peak intensity is larger than the one-photon fluorescence peak intensity. Two-level model can account for the behavior of saturation fluorescence.

Both crystallographically unique Zn atoms exit as an octahedral geometry. The four equatorial positions of Zn1 atom are occupied by the carboxylate-oxygen atoms of the two tartrates, and the two oxygens of the left four carboxylate-oxygen atoms coordinate to two different Zn2 atoms, respectively, forming infinite coordination polymer chains. The left two of the trans equatorial positions of Zn2 atom are completed with two oxygen atoms of two water molecules. The axial positions of both Zn atoms are occupied by the nitrogen atoms from different 4,4'-bipyridine molecules to give a 2D rectangular-grid layers with a cavity dimension of 0.51165(3)nm×1.13896(5) nm. A three dimensional network is formed by the crystallization water chains joined by the carboxylate-oxygen atoms through hydrogen-bonding interactions.

We used NCAR/NCEPT anew analyze data and the method of bilinearity insert to fix on profile distribution of several physical field in the air on observation point and the stream field of 700hPa. We primary discussed the possible mechanism to influence aerosol size distribution.The atmospheric condition of 1000hPa~700hPa level had great influence on aerosol size distribution, and influence on coarse particle mainly below 850hPa level. The horizontal wind velocity of 925hPa level is a primary gene which contributed to coarse particles in the air. Vorticity profile especially below 700hPa level is a key gene to influence diffuse and convergence of local aerosol. The air vertical motion velocity greatly influenced aggregation and remove of aerosol particles. The vertical distribution of air temperature mainly influenced vertical transportation of aerosol.

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。
