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.

In the fourth chapter, firstly it introduces the Boolean functions algebraic expressions of the 2-value clock-controlled stop-and-go generator and Gunther generator. It reveals the balanced property of the two kinds of Boolean functions, and studies the Walsh cycle spectrum and the autocorrelation function. It also obtains the coincidence rate of their output sequences with affine sum of some bits of input sequences, and analyzes their ability of resisting the best affine approximation cryptanalysis and differential cryptanalysis. Secondly, we properly present a new definition of the Best Affine Approximation, namely BAA on the Boolean vector functions, followed by the spectral characteristic of such defined BAA attacks through using the decomposition formula of the union distribution for random variables. A lower bound of such BAA attacks is proposed. Finally, we also study the spectral characteristic of the second kind of nonlinearity of Boolean vector functions, followed by a higher bound of such nonlinearity. Furthermore, the limited relationship between the second kind of nonlinearity of Boolean vector functions and the linear structure of the linear combination of every component is analyzed.

The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.

白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm,与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比,具有向短波长方向移动的特点,据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩;长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征,而基性超基性岩石显示Fe2+和Fe、MgOH特征,利用不同的铁价态和次要矿物可以区分它们:ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度;砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物,在221 μm(band 6)存在有特征的吸收谱带,并且在165 μm(band 4)具有较高的反射率,而蓝片/绿片岩在221 μm(band 6)反射率较高,不具有明显特征吸收谱带,同时其在165 μm(band 4)反射率较低,因此蓝片/绿片岩ASTER band4/band6 比值低。

Three types of base asphalt and six SBS were used to produce SBS modified asphalt. The interaction of SBS modified asphalt was discussed in different states between the base asphalt and SBS based on their compositions. Through the traditional tests, such as penetration, soften point and ductility, and US SHRP tests, the results indicated that influences to affect the temperature susceptibility, high and low temperature performance, aging characteristics are base asphalt, SBS types and their dosages. The functions of penetration to viscosity and complex shear modulus G~* to complex dynamic shear viscosity η~* were set up, and then theviscosity-temperature susceptibility of wide temperature span and the calculation method of low temperature viscosity were obtained."Process" evaluation criterions, high grading critical temperature T_ and low grading criticaltemperature T_ , were suggested according to the high and low temperatureperformances of SBS modified asphalt. Using the experience of Repeated Creep and Recovery Test for Binders, a new high-temperature evaluation index,modification rutting factor G~*~(-9) was obtained. The results after RTFO and PAV aging indicated that traditional tests didnt differentiate base asphalt and SBS modified asphalt, but dynamic mechanics temperature spectrum and G*-5 black chart clearly reflected the influence of aging to the SBS modified asphalt. With the IR and GPC tests, the reason of aging to the SBS modified asphalt were due to asphalt phase oxygenated and SBS phase depredated.

The next development in musical notation were "heighted neumes", in which neumes were carefully placed at different heights in relation to each other. This allowed the neumes to roughly indicate the size of a given interval as well as the direction. This quickly led to one or two lines, each representing a particular note, being place on the music with all the neumes relating back to them. At first these lines had no particular meaning and instead had a letter placed at the beginning indicating which note was represented. However, slowly the lines indicating middle C, and the F a fifth below, became most common. Having at first been merely scratched on the parchment, the lines now were drawn in two different colorded ink: usually red for F, and yellow or green for C.

音乐记谱法的再一次新发展是heighted neumes,这种记谱法标识出音符之间的音高关系,这样就使得纽姆谱可以粗略并直接地标记出指定音程的增减,这样的标识方法导致了谱上一线或者二线的出现,每条线代表一个特定的音符,这个音符与纽姆谱中所有的音符的音程关系都能被标识出来,最初这些线并没有什么特殊的含义,反而会有一个字母被放在开始的位置表明代表哪个音符,渐渐的,线代表中央C或者比C低五度的F 变得最常用,这些一开始只不过在羊皮纸上刮出的线,开始用两种不同的颜色书写,红色代表F,黄线或者绿线代表C,以上的这些便是我们所知道的音乐记谱法发展的开端。
