expression error
1.Abstract: This paper, in terms of conception, logic and form, deeply and systematically analyses and researchs some important problems in the expression of error and uncertainty of measurement, and reterates the definition of error, result and uncertainty of measurement, coverage uncertainty may be used instead of expanded uncertainty, as well the opinion of fixed quality of error and fixed quantity of uncertainty of measurement, which the author once put.
2.Look from recognition factor, what one does not expect of medical treatment reason is behavior person to know perfectly well now produce harm result possibly perhaps necessarily; And expression of medical treatment error is behavior person to arrive to although ought to foreknow,endangering the happening of the result, but did not foreknow actually, just perhaps see beforehand look in him and the possibility of unreality.
3.First the average and worst Bit error rate(BER) expression of QS-CDMA system was deduced, when the synchronous error is uniformly distributed within the symmetrical area.
4.(The only time you won’t get a compile-time error is when x and y are boolean, in which case x = y is a legal expression, and in the above case, probably an error.)
5.Abstract: A group of phase shifting algorithms is derived by the method of undeterminedcoefficients (UCM).The unknown coefficients are set in a general algorithm expression,and then solved by adding bonding equations according to error compensation requirements.Thus the algorithm design and error alalysis are carried out simultaneously.Phase shifting algorithms derived by this method are insensitive to one or more error sources which are considered in algorithm design.
6.In order to design and fabricate Computer-Generated Hologram(CGH) used in military optical systems, we have to fit out the analytical expression for object wavefront. Adopting high order polynomials fitting would increase not only calculation error but also calculation time in coding computer-generated hologram and solving basic equation.
7.Bessel method gets its solution through the ellipsoidal integral equation by simple iterative means with no error estimate expression.
8.In Java, the result of this expression is not a boolean, and the compiler expects a boolean and won’t convert from an int, so it will conveniently give you a compile-time error and catch the problem before you ever try to run the program.
9.At the same time, the uncertainty of the measurement result of the error of indication about low magnitude DC amperemeter in the above-mentioned according to the requirement of the JJF1059-1999 “Evaluation and Expression of Uncertainty in Measurement” is evaluated.
10.The effects of the longitudinal and transverse error of grating in the optical pick-up head of VCD,DVD,and CD-ROM during manufacturing on the transmittance and the ratio of intensity between the assistant and reading beam are analysed numerically by using the general expression of diffraction efficiency obtained from the scalar diffraction theory.
