The results of calibration of 4He in desorption system show that the correlation coefficient is more than 0.99 and the contribution of memory effect can be ignored. The contribution of ionized atom T(superscript +) for partial pressure of m/e=3 is very little and is determined according to I+≈0.01I(subscript T2)+, so the measurement of 3He can be done without interference of T(superscript +). The relationship between gases release rate and annealing temperature can be obtained after the data are smoothed and differentiated.

According to the computational stability analysis conducted to the linear term time difference scheme in simple harmonic motion equation, one new semi-implicit integration scheme also is designed. By adopting a kind of revised time-explicitdifference scheme to these linear terms still included in spectral model governing equations, this defect of spectral model only partly used in semi-implicit integrating scheme, can be overcome to some degree.

Fractal is a subdiscipline of nonlinear area, researches on fractal characteristics of the deoxyribonucleic acid sequence may reveal some secret hidden in the DNA sequence during the process of biological evolution. Chaos Game Representation was proposed as a scale-independent representation for genomic sequences by Jeffrey in 1990. This technique, based on iteration function system, represents the word distribution statistics in DNA sequence as the fractal graphic. Therefore, we can get the distribution of sequence through analysis of fractal theory.

In chapter 4, the plane-radial and plane-parallel flows for Newtonian fluid in fractal porous media are analyzed. Based on the same assumption as that in chapter 3, the expressions for porosity, flow rate, velocity and permeability for both radial and parallel flows are developed. The proposed expressions are expressed as a function of tortuosity, fractal dimension, maximum and minimum pore diameters, and there are no empirical constant and every parameter has clear physical meaning in the proposed expressions.

In our approach, a two-block message is still needed to produce a collision, the first block being only one MSB different while the second block remains the same.

本文所提出的1-MSB输入差分碰撞技术中，仍然采用两个消息分组，但其中第一个分组仅第九个消息字的最高位需要差分，而第二个消息分组可无需差分，即第二个消息分组碰撞是一个伪碰撞（Pseudo-collision）。

However, when sitting for the learning achievement posttests, the experiment group, especially the mediocre and low achievers perform better than the control group. Therefore, we propose that the Embedded-Composite Assessment in the teaching is helpful for the experiment group to learn Factorisation, especially for the experiment group's mediocre and low achievers.
