This paper presents a three - phase harmonic power flow algorithm using phase components and back - forward sweep method to solve the disconvergence when the three - phase transformer harmonic model was used . the example result presented the method was feasible and 本文针对在进行三相谐波潮流算法时因引入三相变压器谐波模型而可能导致计算结果不收敛问题,提出了谐波潮流计算的相分量法,其中引用了前推-回代法。
It is found that , tinder certain conditions , the first or the second perpendicular phase component of the multi - mode functional superposition stale ligh field can present any generalized nonlinear equal - power higher - power sum - squeezing effect which changes periodically 结果表明,在一定的条件下,该态的第一正交相位分量(即广义磁场分量)和第二正交相位分量(即广义电场分量)分别呈现出周期性变化的广义非线性等幂次高次和压缩效应。
We researched the influences of systhesis temperature , heat preservation time , eu + concentration , reduction surrounding feeling and flux on luminescent properties of sral2o4 : eu2 + phosphors , optimized the experiment conditions and reduced systhesis temperature about 100 c . we found that the systhesized sample ' s luminescent brightness is better with increasing systhesis temperature , but the phase component is more complex . we found that the luminescence brightness of sample appear a increasing process at first , and then a reducing one with the raise of eu2 + concentration , it indicated that the luminescence brightness is not better if the eu2 + concentration is too high or low . we found that the systhesized sample can not bright at too long heat preservation time , and the luminescence brightness is lower at too short heat preservation time . we found that particle diameter is bigger , the wavelength of emission peak is longer 研究发现合成温度高,合成样品的发光效果好,但物相组成也较复杂; eu ~ ( 2 + )离子在一定掺杂浓度范围内,合成样品的发光亮度先是出现一个提高过程,然后是一个降低过程,说明eu ~ ( 2 + )离子浓度高或低都不利于合成样品发光;保温时间较长,合成样品不发光,保温时间较短,合成样品发光效果不好,只有合适的保温时间才能合成发光效果好的样品;合成样品的粒径大小与发射峰的位置具有一定的关系,粒径越大,发射峰越偏向长波方向;助熔剂对样品的合成温度和发光性能都有影响,助熔剂的量较低时,主要表现为助熔作用,对发光影响不大,助熔剂的量较高时,使得样品发光亮度降低和余辉时间缩短;还原方式的不同,合成样品的发光性能也不一样。
In allusion to the requirement , a new multiphase - flow measuring technology based on the optic - fiber sensors is considered . proportion of components can be obtained by measuring multiphase - flow ' s optic refractive index . real - time distinguishing oil quality will be realized , without the need to separate out individual phase components 针对这种需求,提出了一种基于光纤传感器的多相流计量技术,根据多相流体光折射率的变化推算出各组分的比例,无需对多相流进行分离就可以实现对原油品质的实时判别,从而达到快速修正采油工艺的目的。
