This thesis mainly focuses on two things, one is the simulation of the thickness of top coal detection, the other is the application on the modulus maximum of wavelet analysis,singal singularity and wavelet packet denoising.

This article has thoroughly excavated the significance of studying useful geography and cultivating students’geography ability ,that is ,studying useful geography connotation,geography ability connotation ,the organic relation between the two things as well as certion attempts at studying useful geography and cultizating students’geography ability in teavching practice .

Among the F1 hybrids of (CS ditelocentrics ×Xiaoyan No. 6) F two things were found. One, the pairing frequencies of telocentric chromosomes 1AL, 2AS, 5AS, 6AS and 7BS were lower than the C value (90.1%) of (CS×Xiaoyan No. 6) F1 significantly at 1% level, which confined the two alien segments within these five chromosome arms.

In order to meet the consumer demands just right, enterprises should do two things: first, to look for the best combination of the quality and cost through Value Analysis so as to realize essential needs with the minimum cost;

The author predicts that as course providers purchase more telematics equipment, two things will happen.

Internal and external locus of control subjects were given information about another person's outcome which indicated two things about organizational standards: how easy or difficult they were to meet and how stringently they were applied.

To make the case for identification as unambiguous as possible, this paper has done two things.

While the Internet keeps its penetration into every facet of life and every corner of the globe, two things stand out.

Forgiving, long encouraged by practitioners of Rational Emotive Behavior Therapy (REBT), is shown to be an elegant antidote to anger requiring recognition of two things.

First of all, this paper discusses how to choose smoothing coefficient in accordance with the grid size of space. Secondly we study the influence on the solution of the differential equation by adding frictional term in the vorticity equation, and then show how to choose suitable frictional coefficient in this case. Thirdly we discuss the influence for computational stability of the finite difference scheme after adding frictional term in the vorticity equation. It is shown that the computation is stable, if...

First of all, this paper discusses how to choose smoothing coefficient in accordance with the grid size of space. Secondly we study the influence on the solution of the differential equation by adding frictional term in the vorticity equation, and then show how to choose suitable frictional coefficient in this case. Thirdly we discuss the influence for computational stability of the finite difference scheme after adding frictional term in the vorticity equation. It is shown that the computation is stable, if taking the frictional term in the (n-1) time layer in the normal centered time difference scheme. If taking the frictional term in the n time layer, then the computation of the difference scheme is unstable. At the same time, the time forward difference scheme may be stable also after adding frictional term, but the frictional coefficient required is then much larger. Finally, we discuss the relation between the smoothing process and frictional term for numerical prediction using the vorticity equation. From the viewpoint of computation, the two things are not equivalent. But we might determine suitable smoothing coefficient by comparing the smoothing process in a diffusion equation.

In this paper we shall sum up two things : 1) how we have improved Mr. M. N. Wilson's experimental apparatus so that it may be used in measuring the A. C. loss of a superconducting solenoid; 2) how the loop we have calculated according to Mr. Irie's model and the loop we have obtained in an e xperiment with the improved apparatus agree with each other.

Emperor Xian Feng(Yi Zhu)and his brother Prince Gong (Yi Xin)were not getting along well.Two things account for the occurrence:firstly,Yi Xin being proud of his ability wanted to scramble for power;secondly,Yi Xin forced Yi Zhu to invest his own mother,the imperial dowager consort Jing,with imperial empress dowager. Following this,Yi Xin was removed from grand councillor and other offices and did not continuously enjoy the trust of the Emperor Xian Feng.
