查询词典 faults

This paper provides a method of variable integrity testing to detect the faults of software By checking the definition domain of the variable itself and the restriction condition of consistency between variables, we only need to determine the bound of each output data, rather than the exact value Although the output of testing case cannot be easily caught, this method can improve the efficiency of detecting faults Furthermore, the checking point is not limited to the final output place, but spreads over the reference places in the program code to key variables just like those at the checkpoints under debugging As a consequence, the testing becomes more precise

由于软件测试用例的输出部分很难确定，而通过测试变量自身的定义域和变量间的一致性约束关系，只需要确定输出值的范围而不用知道其确切的值，就可以提高了错误检测的效率同时，检测的范围不局限于程序最后的输出结果，而是散布在程序中的各个有意义的变量，正如调试过程中设置断点观察的那些变量，使得检测错误更加精准1 引言软件测试的本质在于针对要测试的内容确定一组测试用例[1] 测试用例分为输入和输出两部分功能测试和结构测试等基本的软件测试方法，都比较关心测试用例的输入部分定义域的确定，而对测试用例的输出部分考虑得较少例如，边界测试和等价类测试[2 ] 只考虑测试用

The protective relay is very important factor to avoid unselected trip under complex faults between double circuit lines, and to enhance the reliability of power supply. In order to improve the performance of the relay devices during evolved faults, an evolve fault criterion used for power system EHV transmission lines is proposed in this paper.

同杆并架输电线路发生各种故障时继电保护动作的正确性及可靠性将极大地影响电力系统的供电可靠性和运行稳定性，因此对配置于同杆并架输电线路继电保护的研究有着十分重要的意义。

Vertically, slop-moving turbidity fans are located on the location where the middle term base levels transformed from rising stage to falling stage. On the plane, the slop-moving fans are distributed in the downthrow of depositional faults and the palaeogeomorphological lowlands between these faults.

该类扇体的分布主要受基准面旋回变化、同生断裂及沉积古地貌等因素所控制，垂向上主要位于中期基准面由下降到上升的转换位置，平面上要分布于同生断层下降盘及其之间的古地貌低洼处。

Car magazine. That is quite an achievement: Jaguar ranked worst for reliability in the survey, with faults reported in almost half its new cars last year. Some wealthy drivers may find such faults endearingly old－fashioned; most do not.

这是一个了不起的结果，调查中Jaguar被评为最不受信赖的车型，缺陷报告差不多有一半是来自于去年购买的新车，有些有钱的用户觉得车型过时是缺陷，然而大部分人不这么认为。

Tectonic subsidence and deposition sedimentation were primarily controlled by basin border normal faults. Uplift of basement rocks of the footwall was due to the tilting of border faults and became main provenance areas.

盆地构造沉降和沉积充填过程主要受边界正断层的控制，断层下盘基底岩石的抬升与盆地边界正断层活动相关，从而成为盆地主要的物源区。

It was suggested that the risk of active faults can be reasonably explained by the history of the faults and their occurrence period, while the risk of groundsill seismic liquefaction was examined in the field with penetration test.

活动断裂的危险性主要根据断裂的活动时期、断裂不同部位的活动性以及评估区距离断裂活动部位的远近程度进行评估。

It was suggested that the risk of active faults can be reasonably explained by the history of the faults and their occurrence period,while the risk of groundsill seismic liquefaction was examined in the field with penetration test.

活动断裂的危险性主要根据断裂的活动时期、断裂不同部位的活动性以及评估区距离断裂活动部位的远近程度进行评估。地震砂土液化判别采用现场标准贯入试验进行评估。

Generalized Likelihood ratio Test and Optimal Parity-vector Test methods to detect and diagnose soft faults from sensor redundant measurement system in SINS are researched very carefully from a point of view of their effectiveness to detect and isolate soft faults.

对SINS中冗余配置的传感器量测系统的软故障，研究了目前常用的广义似然比检验和最优奇偶向量检验方法，主要讨论两种方法的有效性问题。

As far as reason for deficiency, the fault expert database is built for helping administrators determine the reason for deficiency;. As for failure prediction,the mathematic models,the logarithmic normal distribution model of network software faults and the exponential distribution model of network hardware faults,are established.

对于故障原因，建立了故障专家库以帮助管理人员确定故障原因；对于故障预测，建立了数学模型——网络软件故障率的对数正态分布模型和网络硬件故障率的指数分布模型。

The preservation conditions of oil-gas reservoir about rift-subsidence basins inc lude tectonic evolution of basin, sealing histor y of faults after the accumulation of oil and gas, tectonic uplift and denudatio n, magmatic activity,dynamics of ground water, seal of cap rocks, a nd seal of the major faults, etc.

以盆地构造演化史研究为基础，对成藏期以后断裂的封闭史、构造抬升剥蚀、岩浆活动、地下水活动、盖层封闭和控油断层封闭进行了定性和定量分析，总结了断陷盆地油气藏保存条件的研究内容和以模糊评判为主的评价方法。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
