The local decision space partitioning is given in the sense of maximum Bhattacharyya distance criterion. The optimality and the non-triviality of the partitioning scheme are proved. The reasonability of using Bhattacharyya distance as partitioning criterion is analyzed. The simulation results show that the partitioning method based on Bhattacharyya distance criterion is superior to that based on J-diversity criterion.

研究了基于 Bhattacharyya 距离准则的决策空间优化划分问题，求出了在 Bhattacharyya 距离最大意义下的决策空间划分方法，证明了这种决策空间划分方法的最优性和非退化性，分析了选择 Bhattacharyya 距离作为划分准则的合理性，并进行了计算机仿真比较，结果表明基于 Bhattacharyya 距离准则的决策空间优化划分优于基于最大 J-散度准则的决策空间划分。

Fuzzy distance of the theory of fuzzy sets an important component of the fuzzy set theory from the early stage of development, Fuzzy Sets distance has been attracting a large number of the concerns that people use real theory of practice with a non-negative real numbers to measure the distance of fuzzy sets, is through the appropriate transform its alluding to the real axis.

模糊距离是模糊集理论的一个重要组成部分，从模糊集理论发展之初，模糊集的距离一直吸引着众多的关注，人们沿用实数理论中的作法，用一个非负实数来度量模糊集的距离，也就是通过适当的变换将其影射到实数轴上。

In order to obtain the reliable and accurate headway distance data, a state space model for distance data filter is established and then a new data fusion and estimation algorithm based on Kalman filter principle is developed. Its recursion formula is obtained. Taking the distance measurements of machine vision and laser radar as inputs, this fusion and estimation algorithm can output more reliable and accurate fusion data in real time.

建立了距离滤波的状态空间数学模型，提出了一种新的基于Kalman滤波原理的距离数据融合估计方法，推导出融合估计的递推公式，对来自机器视觉和激光雷达的距离数据进行融合估计，以减少距离数据的噪声，提高其可靠性与准确性。

Protection The whole protection scheme for double-circuit lines on the same tower consists of split-phase current differential protection or split-phase composite distance carrier protection and zero-sequence directional comparison protection as main protection, and DPFC distance protection, step zones distance protection and zero-sequence directional over-current protection as backup protection.

2.2.1 。保护整个保护计划的双回线同杆包括分相电流差动保护或分相复合距离承运人的保护和零序方向比较保护为主要保护和DPFC距离保护，加强保护区的距离和零序方向过电流保护作为后备保护。

Beams which are part of a truss shall use the distance between panel points as their unbraced lengths, or if the panel has connecting major members, the unbraced length shall be based on the distance between panel points or connecting members, whichever is the shorter distance.

作为构架上的一部分的横梁将节点之间的距离作为无支撑长度；或者，如果面板已经连接到主要部件上，无支撑长度应该以节点或连接部件之间的距离作为基础，选择最短距离即可。

According to range of the focal distance, dropping UV glue which is crystalline and unexpensive into lens cavity with UV rays, and then forms as soon as solidifies the convex lens. Combining UV curing glue convex lens and variable focus lens, the focal distance range achieves the 8.3~24.5 mm low focal distance effect.

於此之后根据变焦效果的需要，利用UV胶透光性佳、成本低，将UV胶滴定於透镜腔体中，形成一凸透镜，藉由变焦透镜与UV胶透镜结合，焦距变化达到8.3~24.5mm范围的低焦距效果。

To get the observer's Lat.and Long.just by pressing a button without the sea horizon to turn to,we should know clearly the relationship between the accuracy of zenith distance observed and the accuracy of a position fixed,the causes of the errors of zenith distance observed,what accuracy of zenith distance observed could be obtained and what accuracy standard should be used.

要在无水天线测天时一按按钮就可定出较精确的船位经纬度，必须弄清天体顶距测量精度对定位精度的影响，弄清顶距测量误差产生的原因，可达到的精度及选用适当的精度标准。

According to the engineering practice, the theoretical basis and method that survey directly the horizontal distance and height difference by the total station system as fourth grade and below fourth grade control network are put forward instead of surveying slant distance and zenith distance.

摘要根据工程实践，提出了用全站仪直接测量平距、高差来代替测斜距、天顶距作四等及四等以下控制网测量的理论依据和方法，并以张河湾抽水蓄能电站施工控制网为例进行了比较计算。

Nei'genetic distance showed Schima superba and Cryptocarya chinensis hadsmall genetic distance between every two subpopulations of each own,but Castanopsischinensis had high genetic distance between every two subpopulations of own.

Nei遗传距离结果表明，荷木和厚壳桂两两亚种群间都有非常小的遗传距离，而锥栗却有大的两两亚种群间遗传距离，表明荷木和厚壳桂亚种群间个体的差异小，有较少的位点频率发生变化；而锥栗亚种群间个体的差异大，有较多的位点频率发生变化。
