In order to get a better result, a better experiment method for low energy region, measuring the γray (59.5keV) of ~(241)Am then correcting the measurement result with different correction and comparing with reference value , was used in this article.

Experimental sample with special surface was designed through error compensation by correcting NC data, and experimental proof for error compensation was conducted on MAKING machining center FNC86-A.

Methods 85 patients with Kaliopenia used micro-injection pump to infuse 10% Potassium chloride via central vein at 5-15ml/h(6.65~20mmol/h) speed for correcting kaliopenia. Strict monitoring and nursing during 10% Potassium chloride infusion were done.

The effect of correcting astigmatism of -0.59±0.38D occured(48.8%<-0.50?D and 51.2%≥-0.50?D). Axis direction of real corrected myopic astigmatism was 180°-44°～180°+44°.

All patients regain effective visual acuity. The best correcting visual acuity is 0.5 or better in 17 eyes(51.5%),0.3～0.4 in 12 eyes(36.4%),0.1～0.2 in 4 eyes (12.1%).

After correcting defocus and astigmatism,the average visual acuity of subjects is 1.0,the CSF value is about 52 for lower frequency 20 c/mm and about 1 for higher frequency 80 c/mm.

The theory of linear error-correcting codes from algebraic geometric curves (algebraic geometric (AG) codes or geometric Goppa codes) has been well-developed since the work of Goppa and Tsfasman, Vladut, and Zink in 1981-1982.

In this paper we introduce to readers some recent progress in algebraic geometric codes and their applications in quantum error-correcting codes, secure multi-party computation and the construction of good binary codes.

It is based on predicting the trajectories of each of the nonlinear systems and correcting them by the deviation of the prediction from the desired value.

The ability of a discrete dynamic system for correcting functional errors is investigated.

The latter is preferentially exhibited towards mispaired (non-canonical) nucleotides, this being the reason why APE1 is considered as a proofreading enzyme correcting the misincorporations introduced by DNA polymerase β.

An experimental verification of the theoretical peak current equation forreversible electrode reactions of the Randles-Sevcik oscillopolarography, i_p=Kn~(3/2)D~(1/2)m~(2/3)θ~(2/3)α~(1/2)cμΑ, is carried out with both single- and multisweep methods.

An experimental verification of the theoretical peak current equation forreversible electrode reactions of the Randles-Sevcik oscillopolarography, i_p=Kn~(3/2)D~(1/2)m~(2/3)θ~(2/3)α~(1/2)cμΑ, is carried out with both single- and multisweep methods. Themultisweep method is essentially that of Delahay, while a simplified circuit isdevised for the single-sweep procedure. The constant K in the above equation has been worked out by Randlesand Sevcikc, but their values differ by some twenty-one percent. Experimentalresults as to which K value is correct have been contradictory. The authorspoint out that Sevcik's value of K is too low, due to the error in choosing too largea unit in his numerical integration. By taking smaller units and reperformingthe integration, the K value increases and approaches that of Randles. Thus thecorrectness of Randles' K value is ascertained and this value is used in calculatingthe theoretical slope. Their single-sweep results, with concentrations from 2×10~(-4) to 1×10~(-3) m/l andα~(1/2) from 1 to 4 volts/sec, agreement between experimental and theoretical slopesis obtained in the case of Tl~+ in m NaCl. In the case of Cd~(++) in m NaCl, experi-mental results deviate from the theoretical value, and the deviation increases withincreasing c and α~(1/2). Contrary to an unproven idea of Delahay, i_p obtained bymultisweep method is higher than that by the single-sweep procedure. However,in calculation of the theoretical values, a value of 15.0×16~(-6) obtained by polarLographic method is used for D of Tl~(+) in m NaCl. The use of the value of Dat infinite dilution is thought to be unjustified. If a D value of 15.0×10~(-6) is used,Delahay's results of Tl~+ in KNO_3 would be higher than the theoretical equationinstead of agreeing with it. This fact seems to support the findings of this paper. Various methods of correcting for capacity currents are compared and discus-sed. The authors point out that at α~(1/2) less than 2 volts/sec, the method of drawingan hbrizontal line introduces no appreciable error while at, high α, various methodsyield different results. This fact lowers the accurraey of data obtained at high α. The iR drop in the electrolytic cell and on the series resistance causes themeasured α to be different from the a actually applied on the drop electrode. Anelementary approximate correction of this effect is mentioned. Results after thiscorrection show that the deviation of Cd~(++) from theoretical at high c and α maybe due partly to this effect.

We describe in this paper an experiment using a cloud chamber in a magnetic field of 6200 gauss to determine the average total cross-section of the direct production of electron pairs in aluminium by high energy electrons generated in cascade showers and having energies larger than 30 Mev. We have found after correcting for the spurious events 8.1 electron tridents, which were produced actually by electrons. This figure corresponds to a mean free path of 672±585 cm. or an average total cross-section of...

We describe in this paper an experiment using a cloud chamber in a magnetic field of 6200 gauss to determine the average total cross-section of the direct production of electron pairs in aluminium by high energy electrons generated in cascade showers and having energies larger than 30 Mev. We have found after correcting for the spurious events 8.1 electron tridents, which were produced actually by electrons. This figure corresponds to a mean free path of 672±585 cm. or an average total cross-section of (0.25± 0.22) X 10-25 cm2, for trident production. In the treatment of data, the elimination of spurious tridents has been appropriately considered. The formulas of the total cross-section derived by Bhabha[8] and by Murota et al[11] have been applied in accordance with our experimental conditions to compute the total cross-section. Finally, comparison between the theoretical and experimental values has been made. Our experiment is in fair agreement with the theory of Murota et al. While not in contradiction with that of Bhabha.

In this paper various factors influencing the image quality of plane grating spectrometer are discussed in detail. By means of vector elgebra a general formula is given for the form of the spectral lines in relation to the form of the entrance slit. A formula describing the angular dispersion of the spectral line resulting from a circular slit is also given. Investigation on the optical performance of the Ebert-Fastie grating spectrometer shows that among various residual optical aberrations, due to unsymmetrical disposition of the incident and diffracting beams with respect to the grating surface, coma is the most serious image defect. This can however be corrected by changing the focal length of one of its reflecting mirrors and placing it at a definite distance from the other mirror. It is also shown that residual aberrations can be well eliminated by placing an aspherical correcting plate near the grating surface. By the latter means there is the potentiality of greatly improving the performance of the instrument; either the volume of the instrument may be greatly reduced where shorter focal length optical systems can be used, or much better light gathering capacity can be achieved without sacrificing its monochrometicity when the spectrometer is used as a monochrometor.
