查询词典 minimum condition

On the other hand, with the purpose of fuzzy feature extraction and fuzzy classification device design, the undulatory property of maximum and minimum scattering power corresponding respectively to the maximum and minimum eigen-polarization has been investigated in frequency domain. Furthermore, the anisotropy polarization degree of target, which is determined by both maximum and minimum scattering power of target, has been studied; meanwhile, the dynamic changing characteristic of eigen-polarization on Poincare polarization sphere has been investigated by means of the conception of polarization frequency stability, the research result shows that PSD value has a big jump near π, forming a sharp pulse, and different target has their individual distribution property of PSD pulse.

另外，围绕目标模糊特征提取及模糊分类器的设计，研究了目标最大、最小本征极化所对应的目标最大、最小散射能量随观测频率的起伏特性，考察了由目标最大、最小散射能量共同决定的目标的各向异性极化程度；同时，采用极化频率稳定度的概念，研究了本征极化在Poincare极化球面上的动态变化特性，在最大、最小散射能量相等的频率点上，PSD曲线呈现为幅度接近π值的尖锐脉冲，反映了目标极化散射结构对这一频率跳变极为敏感，但不同目标的这种PSD曲线特征又有很大的不同。

In a method for retrieving sequences having a minimum PAPR in an OFDM (orthogonal frequency division multiplexing) system, by using characteristics in which all sequences of the OFDM system are classified into cosets having the same PAPR, PAPRs of sequences in which early two elements are fixed as '0' are calculated. A sequence having a minimum PAPR is selected from among the calculated PAPRs, and sequences allocated to the coset in which the selected sequence is included are retrieved as sequences having the minimum PAPR.

The reason of low system efficiency of the mechanical lifting is: unavailable match between transformer and asynchronous motor with large capacity of equipment and large self-consumption; large average no load less of Y series electrical machinery (31.4% of the total oilfield electrical machinery) with 2.86kw; limited adjustable extent of stroke of the electrical machinery in low-liquid produced wells with minimum value of 4 times per minute for limitation of minimum rotation of the electrical machinery and minimum arc of contact of pulley. Energy consumption will be waste for 1 to 1.5 times per minute is enough.

分析显示，造成抽油机系统效率低的原因主要是：变压器与异步电动机之间匹配方式不合理，设备容量大，自身损耗大；占油田电机总量31.4%的Y系列电机的平均空载损耗大，为2.86kW；低产液井电机的冲次可调范围有限，受电机最低转度和皮带轮最小包角限制，其最小冲次仅可调到4次／min，但1~1.5次／min的冲次即可满足生产需要，造成能耗浪费。
