The multiple image formation of a two-dimensional object by means of a sampling filter of pinhole array without the aid of a lens of any other optical accesories is described. The experimental results thus obtained are in good agreement with the theory.
This paper discusses a new microcomputer education system: ESI5198 compatible education system It can be used for experiments on three types of chip micnprocessors Intel 8031, 0751 and 8098 without any aid of meters The paper also introduces the method for the main interface circuit design and shows the detailed program list of the EPLD device with ABEL language
In geomagnetic observation,when obsolute magnituote instrument,relative record magnetic variometer and aid are broken down,and how to determinate and eliminate these troubles quickly are given in this paper.
The author,in light of own practice,introduce the network analysis technoques and its application in computer aid maintenace manayement system,so as to provide with an effective method for improving enterprise manageement and taking intensive development road.
These proteins functionas molecular chaperones to prevent aggregation of denatured proteins, to assist in folding of nascentpolypeptides, to aid in folding of nascentor to resolulize aggregated denatured proteinsSeveral classes of Hsps have been described including Hsp100, Hsp90, Hsp70, Hsp60, Hsp40,and the small Hsps.
The authors make an analysis of all kinds of factors which hinders the development of the athletics and put forward countermeasures and suggestions in order to provide scientific basis and aid for Beijing 2008 Olympic Games that can become "the point of growth of gold medals"
Methods:Epidemiological analysis and Foxplus are performed based on the data collected from prehospital emergency medical care in 101 accidents provided by Shanghai Medical First Aid Center during 1987～1998.Results:The most prevalent kinds of sudden accidents were:traffic accidents(22 7%),fire(20 77%)and building collapse(12 87%).
Compared with babies aged under 1 year old, the possibility of receiving first aid was significant higher among the injured children aged 1～,2～,4～,6～ and above 8 years old, and OR was 2.73, 2.69, 2.49, 8 82, 2.45. Conclusion It is necessary to make health education on accident and injury of children among parents and childminders.
Finally, the results obtained are applied to assessing the influence of individual observation, with the aid of an example.
Theoretical results are derived that aid in developing an O(n2) algorithm to slove the problem optimally.
Using undetermined function method, the ODE obtained above is replaced by a set of algebraic equations which are solved out with the aid of Mathematica.
Based on the mass spectra search function of GC/qMS with the aid of the discriminability of the geometrical isomer by GC/FTIR and the ability to determine the accurate mass charge ratio (m/z) by GC/oaTOFMS, 68 GC eluants were identified successfully.
tabulaeformis forests was evaluated by an integrated index method with the aid of an analytical hierarchy process (AHP).
