Estimating of substitution number of amino acids is basic statistic methods of measuring evolution distance between proteins,which is the base of researching molecular evolution of protein.

The main works are as follows:Studying the basic statistic regulation of the oil-gas dynamic system applyingsystem theory, and associating with the general structure characteristics of the system,this dissertation has systematically investigated nearly many processes and factorsinvolved in production engineering programming, and summarized a set of theoriesand methods for production engineering programming.

By testing the basic statistic characteristics such as equilibrium, runs and correlation of the binary pseudo-random sequences (viz. TD-ERCS sequences) being generated from the PRNG, and comparing with m-sequences, the logistic sequences, Chebyshev sequences and SCQC sequences, the experimental results show that TD-ERCS sequences have better statistic characteristics.

This dissertation makes a comprehensive evaluation of the simulated CET-4 held by China University of Geosciences in June, 2002 with two fundamental testing factors: reliability and validity, as well as basic statistic research methods in applied linguistics.

The paper puts forward two quick evaluation methods: basic statistic data method and historic damage data method with practical circum stances, puts up the calculation taking the flood storage area of Mengwa in Anhui province, analyses the deficiency of this method

From four aspects of basic statistic element,reference record analysis statistic element,user’s satisfaction degree statistic element and cost statistic element,the author lists and analyzes statistic indexes in virtual reference,illustrates the calculating method and main function for each element,and points out that the purpose of analysis on statistic practical elements is to evaluate dynamically the performance of virtual reference system.

The absolute majority, namely 97.9% of the total students, have used the basic statistic method in their thesis, 75.7 percent could use statistic method correctly.

Through studying the basic statistic, independent and correlation, test of normality , test of fat tail , test of stationary, ARCH effect of Shanghai and Shenzhen Stock market etc, some conclusions can be acquired: The returns series of Shanghai and Shenzhen Stock market is not independent but has a long-range correlation, and is disobedient normally distribution but has obvious peak and fat tail;

An English language teacher should not only have rich academic knowledge, rich teaching experience but also can design test items well and master a lot of basic statistic methods as well.

Combining the existing road condition in Tianjin and adopting a large number of basic statistic materials and diagrams, an analysis on the main traffic problems are given from the aspects of trip, road capacity and the function of road network, transportation planning and land-use, modal split, traffic disturbs, static traffic and management level. Also the levels and relation that caused traffic conflict are obtained through the way of expert investigation.

Although the results were obtained from simple models, there is a good probability of kinetic origin for the basic statistic regularities of fracture.

The module analyzes server logs and generates reports that contain basic statistic data of a community and its members.

The basic statistic in most studies relating anthropometry to performance is the Pearson correlation coefficient.

Section 2 reviews the basic statistic information useful for algebraic BSS methods.

A community analysis function should provide basic statistic data on both of a community and its members for an analyst.

According to the analysis of surface meteorological data of eleven meteorological stations in the area of Hangzhou Bay, three stations (Jinshanzhui, Zhenghai and Hangzhou) are selected in further analysis. Basic statistics of main meteorological elements such as wind, temperature, precipition, humidity, fog and typhoon of these stations arc used to represent the general climatological features in this area. Due to the effect of monsoon the wind direction presents monsoon feature. The wind velocity is greater...

According to the analysis of surface meteorological data of eleven meteorological stations in the area of Hangzhou Bay, three stations (Jinshanzhui, Zhenghai and Hangzhou) are selected in further analysis. Basic statistics of main meteorological elements such as wind, temperature, precipition, humidity, fog and typhoon of these stations arc used to represent the general climatological features in this area. Due to the effect of monsoon the wind direction presents monsoon feature. The wind velocity is greater at the mouth than at the lop of the bay. Because of adjustment of the oceanic air current. The temperature is a little lower at the mouth than at the lop in summer and higher in winter. The humidity of the air is relativity large all the year round. Annual precipitation is usually over 1000 mm and concentrated in the period of March-September.

The basic statistics of 109 metrical traits and the incidences of 63 non-metrical traits in both male and female skulls from Taiyuan, Shanxi are reported in the present paper. The incidences of these non-metrical traits may be of use for a further comparative study. The side differences and the sexual differences of these metrical traits have been revealed by the t-tests. On the average, the orbital breadth, the height of mandibular body at foramen mentale and the breadth of mandibular notch on right side...

The basic statistics of 109 metrical traits and the incidences of 63 non-metrical traits in both male and female skulls from Taiyuan, Shanxi are reported in the present paper. The incidences of these non-metrical traits may be of use for a further comparative study. The side differences and the sexual differences of these metrical traits have been revealed by the t-tests. On the average, the orbital breadth, the height of mandibular body at foramen mentale and the breadth of mandibular notch on right side are significantly or very significantly larger than the corresponding measurements on left side in both male and female group. In male group alone, the orbital height on right is larger and the height of caput mandibular on right is smaller than on left. These side differences probably are related with the right dominence in mastication. The sexual differences in Taiyuan series are generally reflected in a larger size of male skulls. Besides, the averages of the subtense mf-mf, the naso-malar angle and the profile angle of frontal bone in male group are statistically very significantly smaller than the corresponding values in female. Using 8 metrical traits in skulls with man-dibles, the discriminant analysis leads to 92.5% cases of sexual diagnoses in accordance with those based on the morphology of postcranial bones. The discriminant analyses using a few traits in skulls without mandibles or in mandibles alone as their items produce approximately 90% accuracy. These discriminant functions have been formulated, which can be applied in the range of modern Northern Chinese skulls.

The methods for differenticeting and analysing step by step and calculating procedure worked out suited for IBM-SUPER-AT-CH micro-computer were detailed in this paper Calculation and differentiating and analysing step by step can be carried out and uarious basic statistics can be typewrttien by the procedure, which is noted for its applying easily and high-speedcalculation, and is a ideal procedure to differentiate and anlyse.
