It is found that the equations are in a suitable form to investigate flows with helical symmetry, and, for example, to connect upstream axisymmetric flows with downstream helical flows.


We introduce formulae in suitable form for the numerical computation of Mie coefficients and the scattered electrical field in the general case of a sphere with permitivity $$\epsilon$$ and permeability $$\mu$$.


Moments of images are widely used in pattern recognition, because in suitable form they can be made invariant to variations in translation, rotation and size.


This problem can be reduced to the inversion of some operator represented in a suitable form and related to the operator solving the Cauchy problem for the homogeneous EulerPoissonDarboux equation.


Alternatives in experimental design are discussed as means to minimize the need for assumptions and/or to provide data in suitable form as tests of internal consistency.

 The effects of bow shape on calm water resistance of full ship forms with block coefficient about 0. 8 are summarized on the basis of the results of various model experiments. It is concluded that the resistance of full ship forms could often be reduced either by fiffing a bulb of adequate size and suitable form, or by cutting off the forefoot of a conventional bow properly.  本文根据上海交通大学水池实践和船模试验研究的结果,初步总结了C_B约为0.8的丰满船船首形状对静水阻力的影响。大量的试验研究表明:在这类船上,无论采用大球首、小流鼻或使船首底部上翘,不同程度地都能改善阻力性能。  For the needs of researches and predictions of flare activities in the middleterm(101  102days), the first thing is that we should establish a suitable form describing flare activities.We have found that the daily flare indices I/ published by NOAA deviate seriously from the normal distribution.

For the needs of researches and predictions of flare activities in the middleterm(101  102days), the first thing is that we should establish a suitable form describing flare activities.We have found that the daily flare indices I/ published by NOAA deviate seriously from the normal distribution. Through conversion, we obtained the logarithmic flar indices FL corresponding to the order of magnitude of integral radiant intensity from flaresand found that in this case the normal distribution holds good for FL. Consequently, their mean FL and standard deviation σF in any period of time can perfectly statistically describe the level of flare activity in that period.According to the probability theory, using the random number generator, we deduced the approximate values of FL below the thresholds of reporting, and composed the complete alignment FL(t), which describes the continual changes of solar flare activities.We have calculated FL and σF of every cycle of the solar rotation cycles from 1642 to 1684 and found them to evolve correlatively with the slowly varying component of the Sun (solar flux S0 at 2800 Me). The compound correlation coefficient RF = 0.93, and Rσ = 0.46. On the other hand, the relative regressionresiduals .
