The education is the important path of the human resource development and the education investment is then the important part of the manpower capital investment.

But the concern that real deluge combine to cause the international society is then 60 age in 20 centuries later on, particularly is a 2001 occurrence is in the "9.11" of mainland the United States the affairs is after, and is also to caused international society of extensive concem.

The region, southeast west wreath in Guangzhou that Guangdong province is a Chinese freeway to prosper most is then Guangzhou wreath of the segment of southeast west wreath in Guangzhou of the city high speed.

In this paper, we prove that if ss has AK property and ss and ss are strictly monotone,then is a smooth point of ss(E) if and only if (i) |x| is a smooth point of ss and is a smooth point of E for .

Supposed that and are derivationsof A. In this paper, give two necessary conditions: If thereexistsa A (a≠0) satisfied a = 0 and for all x A, there is positive integer n x s. t a n xx = 0, then is a nilpotent derivation;

本文给出了 及 成为幂零导子的两个必要条件: 若存在0≠a A 满足 a = 0,并且对于每个 x A, 存在正整数 n x ,使得 a n x x = 0,则 是幂零导子;

As everything in the universe is the unity of opposites of matter and information, energy is the unity of opposites of material energy and informational energy.

Considering the previous reports and the present study,R158Q was the most prevalent form in PKU patients from European and Latin American countries,IVS4-1G→A was a common mutation inoriental PKU populations. However,F161S and Y166X are two characteristic forms in Chinese.

The D56G90 cold ring-rolling machine is equipment applying to manufacture bearings ring work piece with cold ring rolling technique. Framework is one of the key parts of the machine,and their rigidity affect the accuracy of the manufacturing.

The logistics information is the central nervous system of a logistics system, the quality of logistics information is the key to the logistics information.

As to anabolism rutio of MCP and digesting ratio of cellulose in rumen,both are higher in Stage Ⅱ(8.59±0.24) and(55.14±0.71) than that in stage Ⅰ(6.38±0.53) and(45.06±1.75),showing diffinite significant difference(P<0.01).

The theorem is then used to characterize a class of entire functions that can be reconstructed from their sample values at the points tn = an + b if n = 0, 1, 2, ...

We prove the well-posedness when and construct non-unique solutions for In the second part the well-posedness of the avove IVP for k=2 with μ0?Hs(?n) is proved if and this result is then extended for more general nonlinear terms and initial data.

This is then applied to study the association problem for i.d.

The condition, which is expressed in terms of the intertwining operators of each primary summand of the quasi-regular representation, is then interpreted in the case of the compact Heisenberg manifolds.

An MCA-inpainting method is then directly extended to the case of spherical maps allowing us to treat problems where parts of the data are missing or corrupted.

In this paper the logical structure of contactless telemechanical system for distributed objects is discussed. A simple method of variable system structure for transmitting and receiving telemechanical information is adopted. The idea is that the information oc-curred in every controlled point (station) and the information of some of those objects,which frequently change their states, are transmitted continually and cyclically, while for other objects their information is transmitted only after any change in...

In this paper the logical structure of contactless telemechanical system for distributed objects is discussed. A simple method of variable system structure for transmitting and receiving telemechanical information is adopted. The idea is that the information oc-curred in every controlled point (station) and the information of some of those objects,which frequently change their states, are transmitted continually and cyclically, while for other objects their information is transmitted only after any change in their states. Thus,the speed of operation will be increased, and also the error probability of system syn-chronization will be decreased. For the realization of the variable logical system struc-ture, several blocks are used repetitively. For example, two commutators and one sim-ple logical unit are used to construct a simple automatic sequential encoder, and at the same time, the two commutators are used also to operate as a matrix commutator for receiving telesignalling information etc. Therefore the system is comparatively simplified and attains a higher degree of "minimization".

Analysis of the low frequency response of automatic balancing D-C amplifier with mechanical chopper is illustrated by a typical circuit in this paper. The analysis of dynamic response of the modulation and the demodulation circuits and the auxiliary carrier wave amplifier have been considered more in details. The analysis is based on solving difference equations since the intrinsic working process behaved by the M-D M circuits using mechanical chopper is more accurately described by difference equation other...

Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined...

Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined by comparison with the scattering from oxygen, the results of Wollan for the latter gas being taken as correct. The experimental results are actually compared with Woo's theory of the scattering of x-rays by polyatomic gases and the agreement seems to be satisfactory.
