It is deduced out the equation for typical phase current 's shape of wave under the motor-operated running state in different phase inductive district ,which the change-magnetic pole-DC machine is under the ideal line model & control way of angle-position.

For all crosses in this study, the crosses of upland rice 502 or 65 with ZY-3(Jiahe 99) obtained ideal lines, while there is no ideal line among the crosses with ZY-2 (Jingyin 119) as paternal line.

In order to evaluate the accuracy, rudeness and influence of blurring an ideal line and circle generation method is introduced to produce an ideal image which is to be added with Gauss noises and Gaussian blurring respectively to provide three groups of simulation data for algorithm evaluation.

It is named as 212D(FD)2TD method. The main idea of it is to represent the constitutive equation by a convolution in time domain. Consequently, this newly developed method is used to analyze some of the characteristics of an ideal line antenna in pure water.

Compared with traditional wheelsets,independently rotating wheels have high critical speed and well curving performance on the ideal line without interfer, since independently rotating wheels have no logntitudinal creepage between wheel and rail.

In the process of building socialism harmonious society,it will povide us the basis of ideal,line,material and the masses. Yan′an spirit still have important times value.

We describe all the k-arcs of AG(2,q) the secants of which meet the ideal line exactly in k points.

The maximum error due to orientation of a single line was evaluated for an ideal line, and the analysis revealed that the new equation was less affected by orientation than previous equations.

The salient features of this disease entity with the present day consensus about the ideal line of treatment have been discussed.

The responses of "complex" simple cells, which are an abstraction of pairs of simple cells having real receptive fields with phases in quadrature, to ideal line and edge patterns (events) are studied.

Criteria for how much the regression line may deviate (Maximum Accepted Deviation, MAD) from the ideal line (y=x) have been developed.

After studying thorougly the imposibly complete same of the line source probe and its experimental couditions between the solv- ing boundary conditions of the ideal line sonrce solution,we pro- pose a correction method that stems from the data obtained in our experiments.This method is called“the reduction of two-point formula”.Thus the accuracy and reliability of the probe for meas- uring the thermal conductivity are significantly improved.The applied range of the probe is expanded.The relative error...

The method is based on the reduction of inorganic tin to volatile SnH4 which is bubbled out by carrier gas of pure nitrogen, trapped in a liquid nitrogen trap and then swept to hydrogen flame quartz atomizer to measure its atomic absorbance. The hydride generation, transportation, trap and aromisation were studied. The optimum conditions selected are as follows: reactive acidity, 4μ10-3M HCl, The amoumt of NaBH4, 2% 2ml in 100ml sample; gas flow of nitrogen, 300-400ml/min; gas flow of hydrogen, 220-250 ml/min,...

There are no obvious interferences of elements such as As, Se, Sb when their concentrations are less than 200 times of Sn. The detection limit is 0.0060μg/dm3 and the variation coefficient at tin level of 0.050μg/dm3 is ±8% The calibration curve shows an ideal line in the concentration of 0 000-0.050μg/dm3 Sn with the same slope for both distilled water and sea water With coprecipitation by addition of NaOH to prcconcentration of inorganic tin, the sample storage is facilitated and the sensitivity can be improved by a factor of 5-10 with a recovery of above 95%

The authors proposed a mathematical model and the process program for evdluation of orientation least area value of parallelism error for line to line. At the same time, they apply principle of point-deletion to seek out the datum ideal line which can agree the least conditions.
