  • Where m 0 and f ( t , u ) may be singular at u = 0 . ( 2 ) the present paper deals with positive solutions for first - order periodic boundary value problem . where 0 and f ( t , u ) may appear singularity at u = 0
    (二)研究奇异一阶微分方程周期边值问题正解的存在性其中允许f ( t , u )在u = 0处具有奇性且是一个不于零的常数。
  • 1 m 0 . 5 , the phase - shifted angle 6 is controlled in term of sine law which makes the magnitude of resonant voltage track a reference sine voltage , and the resonant voltage is rectified , filtered , inverted and then the better sine - voltage output is obtained , theoretical analysis and experimental results show that for the resistive load and inductive load , the switches of leading leg of the phase - shift - controlled circuit are always turned on at zvs , and ones of lagging leg are turned on at zvs ( < 0 ) or turned off at zcs ( ( > 0 ) , moreover , all switches in the low - frequency inverter are always turned on and off at zvs , the measured circuit efficiency for rated load reaches up to 88 %
    从功率单向流动角度出发,提出了一种lcc谐振型恒频移相单相高频链逆变电路拓扑,在调制系数0 . 1 m 0 . 5情况下,控制移相角按正弦规律变化,使谐振电压脉冲列的幅值追踪参考正弦电压信号,经过整流、滤波、低频逆变,从而获得正弦度较好的输出电压。理论分析和实验结果证明对于阻性负载或阻感性负载,移相全桥具有超前桥臂零电压开通,滞后桥臂或者零电压开通( _ 0 )或者零电流关断( _ 0 )的软开关特性,而低频逆变器的各个开关均实现零电压条件下的开通与关断。
  • By the ranking model by similarity to ideal point based on m and n , the criterion of cultivated land can ’ t be used as plant cash crops and the criterion of cultivated land should priority used as plant cash crops and the criterion of cultivated land can ’ t be used as construction land and the criterion of cultivated land should priority used as construction land were confirmed . finally , the evaluation of cultivated land grade , realistic class , and potential class were all demonstrated and the result of cultivated land grade , realistic class , and potential class were all verified in a case study in changsha county changsha city , hunan province . by calculated cultivated land coefficient m and n and confirmed c _ m and c _ n of the ranking model by similarity to ideal point , the result 0 . 5032 < c _ m 0 . 9931 was confirmed as the criterion of cultivated land should priority used as plant
    最后以湖南省长沙县作为典型研究区域,实证了耕地等、现实级和潜在级的评价,并分析了其评价结果的可靠性;通过计算耕地经粮系数和建粮系数,及逼近于“理想点”的排序模型中的c _ m和c _ n确定了长沙县0 . 5032 < c _ m 0 . 9931为耕地应优先用作菜地等经济作物用途和0 . 0126 c _ m < 0 . 5037为耕地不应用作菜地等经济作物用途的判别标准;确定了长沙县0 . 5035 < c _ n 0 . 9937为耕地应优先用作建设用地用途和0 . 0139 c _ n < 0 . 5035为耕地不应用作建设用地用途的判别标准;最后阐明了c _ m 、 c _ n在种植业结构调整、耕地保护和土地管理中的应用价值。
