通过定义在元组上的隶属函数反映信息的可信度，对通常意义下的关系代数进行了扩展，每一元组都附一属性函数，定义了模糊属性的含义，用元组间的语义距离表示模糊对象和实体间的相似度，并对该意义下的关系操作进行了相应的研究和讨论。

Average annual Growth Rate Two methods for calculating average annual growth rate are applied in China, one is often called "level approach" or the method of calculating geometric average, which is derived by comparing the level of the last year of the interval with that of the beginning year; the other is called accumulative approach or algebraic average or equation method, which is derived by the summation of the actual figure of each year in the interval divided by the figure in the base year.

平均增长速度我国计算平均增长速度有两种方法：一种是习惯上经常使用的"水平法"，又称几何平均法，是以间隔期最后一年的水平同基期水平对比来计算平均每年增长速度：另一种是"累计法"，又称代表平均法或方程法，是以间隔期内各年水平的总和同基期水平对比来计算平均每年增长速度。

Precision and reliability are two contradictory aspects of the theory of interval estimates. To find a confidence interval of prescribed width and prescribed probability is of groat importance in practical applications, arid thereby sequential procedures have to be employed in many cases.

精确度与可靠度是区间估计理论中互相矛盾的两个方面，寻找同时满足精确度与可靠度的区间估计在实际应用中具有重要价值。

We generalize the concepts of two kinds of discrete distance of interval-valued fuzzy sets based on Hausdorff metric, and introduce a new distance of discrete interval-valued fuzzy sets based on Hausdorff metric and study some properties.

同时我们分别举例说明全空间IF~*(R，d~*和IF~*(R，d_p~*不是完备的，IF~*(R，d~*和IF~*(R，d_∞~*不是可分的。我们还对区间值模糊数序列在这三种距离意义下的收敛性之间的关系进行了讨论，得到一些结果。

Result It showed that tracking error, reaction time, correct rate, category scale, multistage evaluation scale, multi-dimensional scale, latency of P3, inter beat interval , inter respiration interval and blink rate were significantly different among the various tasks. CS,MES and MDS were more sensitive to the total load; ER ,LAT, IBI and IRI were more sensitive to the load of primary task, while RT and CR to that of additional task and BR to the visual load.

结果 追踪误差、反应时、正确率、类别量表评分、多级估量量表评分、多维量表评分、P3潜伏期、逐次心跳间期、逐次呼吸间期和眨眼率在不同任务之间有显著差异(P＜0.05)，CS、MES和MDS对任务总负荷，ER、LAT、IBI和IRI对主任务负荷，RT和CR对附任务负荷，BR对视觉负荷更敏感。
