The results show that when the test portion weight of the proof gold and samples is reduced to 160.00~200.00mg, there has no influence on the result of gold content. Respectively using magnesium oxide and bone ash cupels, the result deviation of gold content in the samples is within the allowable deviation of the national standards. The result of gold content in samples is much more closed to the theoretical value by adding proper copper in the proof gold. The additive amount of silver (2.5 to 2.7 times equal to the weight of the proof gold) in the proof gold and samples has no influence on the result of gold content.

结果表明，当标准Au与样品的称样量降为160.00~200.00mg时不影响其含Au量的分析结果；分别使用镁砂灰皿和骨灰灰皿，样品含Au量的分析结果与理论含Au量的偏差均在国家标准的允差范围内；标准Au中加入适量的Cu后测得样品的含Au量更接近于其理论含Au量；标准Au与样品中Ag的加入量（2.5~2.7倍Au质量）对样品含Au量分析结果的影响不大。

Thirdly, Through the introduction of the Burckhardt road model 、Gim tire model、bus brake model and Time-domain model of road roughness ,ABS system with a fuzzy controller based on the slip rate deviation and deviation rate of change was designed. The ABS system on account of impacts of air suspension and road roughness were analyzed, and its result showed that air suspension system and braking system need joint control.

第三，通过引入了描述单轮特性的Burckhardt的路面模型、Gim轮胎模型、客车制动器模型和时域路面不平度模型，并在此基础上设计了基于滑移率偏差和偏差变化率的ABS模糊控制器，对计及空气悬架和路面不平度影响的ABS进行了分析，进而说明了空气悬架系统与制动系统进行联合控制的必要性。

Analysed from 3 respects here disturb gravitation is right ballistic influence, imitate result makes clear, it is the long-range missile of 10000 Km above to cannon-shot, disturb the influence of gravitation can cause those who exceed the 10-5m S-2 of × of placement deviation;5 of 1 Km to disturb gravitation systematization deviation has apparent effect to missile point of fall.

这里从3个方面分析了扰动引力对弹道的影响，模拟结果表明，对于射程为10000 km以上的远程导弹，扰动引力的影响会造成超过1 km的落点偏差；5×10-5m s-2的扰动引力系统性偏差对导弹落点有明显影响。

Blasthole deviation is composed of three distinct components:collaring, alignment and trajectory deviation.

炮孔偏差严重影响采矿企业的经济效益，过大的偏差造成的不利影响是很明显的，如产生不良的爆破块度、回收率低和矿石贫化。

The original design of coaxial maximum deviation of 0.1mm, measured concentricity deviation after removal of about 0.4mm.

原设计中同轴度最大偏差为0.1mm，拆除后实测同轴度偏差约为0.4mm。

This paper analyzes the deviation of cambered form witch is composed of batten and sheet in concrete construction,and then educes a relationship between width of sheet,deviation of cambered form and curvature radius of camber,in order to solve the problem of assemble spline form work and increase construction quality of concrete curved surface.

分析了用板条和铁皮组装而成的曲面模板在曲面混凝土施工中的误差情况，同时给出了施工中板条宽度、曲面误差、曲面曲率半径之间的关系，以解决好拼装样条模板的问题，从而提高混凝土曲面的施工质量。
