In order to solve the existing ct saturation problem which is met in current differential principle , this paper bring forward the new method to discriminate ct ' s saturation based on bd wavelet transformation 针对电流差动原理中遇到的ct饱和的问题,提出了基于bd小波变换识别ct饱和的新方法。
The bus differential protection based on instantaneous values of currents is the most useful scheme nowadays . but it is easy to be influenced by current transformer saturation and to make misoperation 目前微机保护最常用的方法是电流瞬时值差动保护,这种方法受电流互感器( ta )饱和的影响而容易误动。
But it further inhibited the low affinity system . 1 . 3 effect of k + channel inhibitor on the na + content nem ( 3 mmol / l ) is a specific inhibitor of the high affinity k + uptake system 另一个是不饱和的低亲和k ~ +吸收系统,其一级反应常数k为1 . 1 ,说明nacl胁迫浓度的增加进一步抑制了碱蓬的低亲和k ~ +吸收系统。
For samsung , which trails motorola and nokia corp . in cellphone sales , joining with a fashion designer is a means of distinguishing its wares in an increasingly crowded market 广告对于手机销量仅次于摩托罗拉和诺基亚公司( nokiacorp . )的三星电子来说,与一位时尚设计师合作是使其产品在高度饱和的市场中脱颖而出的一种方式
When the magnetic ( electronic ) field approaches to the threshold and saturation field , the angle is very small , we can linearize and simplify the calculation because the angle is very small 因此计算液晶盒阈值和饱和场强是很重要的问题。对于接近阈值和饱和的情况,可以用小角度近似,把问题线性化,使计算大大简化。
The primary structure is composed of a circle comprised of 15 kinds of molecules , while the 4th and 5th sites of carbon are intergrated with a circle of unsaturated oxygen , and a lipid chian is ligated at the 13th site of carbon 其骨架由一个15元环组成,在环的碳4和碳5位又与一个不饱和的4元氧环相联,在碳十三位还带一个酯基侧链。
For example , at pore - water pressures of zero and greater , ( i . e . below the water table ) , there is a saturated conductivity value ; at pore - water pressures less than zero , ( i . e . above the water table ) , the hydraulic conductivity is zero 比如:当孔隙水压力大于等于0 (如位于水位以下) ,有一个饱和的导水值;当小于0时(如在水位以上) ,导水性为0 。
When the " turbid wind " with almost a saturated sand concentration changes to a refreshing breeze after getting rid of the sand dust around the protective net , it exhibits an even more powerful wind abrasion when blowing across the cliff region 当含沙量几乎饱和的"浑浊之风"在防护网前后卸下沙尘变成清风,在吹过崖区时便显出更强的风蚀作用。
