The existence of this linear relationship, coupled with the cyclical stepper motor only accumulated error without error and so on.

这一线性关系的存在，加上步进电机只有周期性的误差而无累积误差等特点。

Corresponding compensation algorithm without cumulative error was proposed to improve the rotating motion precision with consideration of both accuracy and efficiency. Experiments were carried out and the results bear out the claims with the standard deviation of residual errors decrease by 47.4%.

I am saved at that time " examine immediately " basic characteristic is: 1Of.1POCT cover a range wide, the testing instrument model of same item amounts to 7~8 to plant. 1.2POCT all is placed in clinical the outpatient service of each division, emergency call and ward, the apparatus is almost entire by groom without POCT operation post already card, lack again examine the operation of the member that be not identifier of basic knowledge. 1.3POCT assures measure without quality, examine the specimen is collected, reagent is purchased and save all compare optional, be opposite extremely between the instrument experiment, do not have room endoplasm to accuse already at ordinary times, do not have again judge character between the room, examine quality is in nobody to run state. Of 1.4POCT detect result error is big, repeatability of partial instrument result is poor, the hospital examined 2002 3 hospitals selectived examination randomly in division quality assessment, 45 second large biochemistry appearance detects contrasting POCT blood sugar, its written guarantee...

当时我省"即时检验"的基本特征是：1.1POCT的覆盖面广，同一项目的检测仪器型号多达7~8种。1.2POCT均放置在临床各科的门诊、急诊和病房，仪器几乎全由既无POCT操作岗位培训证，又缺少检验基本知识的非检验人员操作。1.3POCT没有质量保证办法，检验标本采集、试剂采购和保存均比较随意，仪器间无比对试验，平时既无室内质控，又无室间质评，检验质量处于无人管理状态。1.4POCT的检测结果误差大，部分仪器结果重复性差，2002年医院检验科质量考核中随机抽查了3所医院，45例次有大型生化仪检测对照的POCT血糖，其结。。。

The adaptive program is calculated by T-B stress recovery scheme and z-z error estimation, the error is estimated by energy norm of difference of recovery stress and meshless stress. If the local relative error exceeds the limit relative error, then new nodes will be generated at the high error area.

本研究的自适应方法采用TB应力平滑技术和Z-Z误差估计，利用平滑应力和无网格法所得应力解差值的能量范数来估算误差，如果局部相对误差超过了允许误差，则在高误差域插入新的离散点进行加密。

First of all, the valuation errors in TXO of the BS-IV model are the smallest among all volatility models. In the whole, the BS-IVmodel underprices the market value, BS-HV, BS-EV（EGARCH（1,1））and Ad hoc BS model overprice the market value respectively. Next, there exist the linear relationships between the valuation errors and moneyness in TXO mostly. At last, in view of hedging errors, the other thing being equal, the shorter is the maturity, the smaller is the hedging error.

本文的实证发现，在评价误差方面，整体而言，隐含波动性模型对买权及卖权的评价误差最小，隐含波动性模型之理论价格低估了市场价格；而历史波动性模型、EGARCH（1，1）模型及平滑后的历史波动性模型之理论价格则大多高估了市场价格；接著，在评价误差与金融特性关系方面，各波动性模型之评价误差与价内价外程度、股价指数报酬率、股价指数波动性、距到期日及无风险利率等因素，大多具有显著的线性关系。

In order to reduce the periodic current tracking error of the deadbeat control when compensating abruptly changing nonlinear load current, a repetitive controller is plugged into the deadbeat controller. Also, the repetitive controller can alleviate the parametric dependency of the deadbeat control and eliminate the effects on compensation performance caused by the uncertainties in the system.

另外，为了降低无差拍控制对系统参数的依赖型和系统中存在的不确定性对补偿性能的影响以及减小在补偿电流变化剧烈的非线性负载电流过程中存在的周期性的局部跟踪误差，本文在无差拍控制器的基础上，又提出了基于无差拍和重复控制的复合电流控制器。

This research process the ionosphere-free triple-differenced carrier phase observation which consist of double frequency GPS observations from the GPS receiver carried on the CHAMP and 40 IGS tracking stations. Besides, the tropospheric correction model, solid earth tide correction, mass center correction of the satellite, earth rotation correction and antenna phase center correction are incorporated. Finally, determine the satellite short-arc orbit with the pure geometry, kinematic, method.

本研究利用CHAMP卫星上装载之GPS接收器所接收之双频观测量与地面上40个IGS追踪站组成三次差分无电离层观测量，并改正观测量中之对流层误差、固体潮误差、质量中心改正、地球自转、天线相位中心偏差等误差量，以纯几何之动态法求定低轨卫星之短弧轨道位置。

A gear H62 which made in yellow brass with the same mode number m=0.34, 2mm thick and had a center hole, when the gap get C=0.5%t , and punched with compound punching die, and the dimension accuracy reached IT7, the part have a flat surface ,the verticality of tangent plane reached 89.5°, its roughness Ra magnitude are 12.5μm, height of burr are 0.10mm; and the punching part are punched with progressive die, the gap C=7%t , initial accuracy are IT11, and have an more rough surface, even can see the gap with eyes.

例如料厚t=1.5mm的H62黄铜冲裁件，选用C≤40%t单边Ⅰ类小间隙冲裁比选用C≤8%tⅢ类大间隙冲裁，冲件固定误差将加大40%～60%，精度至少降一级。此外，采有无搭边排样，冲件的误差要远大于有搭边排样冲件。无搭边排样冲件。无搭边排样冲件的精度低于IT12级，而多数有搭边排样的冲件精度在IT11～IT9级之间，料厚t＞4mm的冲件，尺寸精度会更低一些。

The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。

Currently, almost all the corrections of radar wave refraction error are based on the assumption that the atmosphere is homogeneous in the horizontal direction, and the azimuth error in the measurement of radar is not corrected.

目前进行的雷达电波折射误差修正，几乎都是建立在假设大气在水平方向均匀的条件下，认为雷达测量的方位角无折射误差，其对于下垫面均匀的平坦地区是可行的，但下垫面复杂地区方位角的折射误差必须修正。

I can still vividly recall the impressive scenes you gave. You were among my friends and relatives who accompanied me from my house to the seaport and when the porters were slow to show up, you obligingly carried my suitcase for me.

你对我的种种感人情意，使我记忆犹新，那天你随着我的亲友从家里送我上轮船，搬运工迟迟不来，你毅然替我提着皮箱上船。

St. Nicholas became the patron saint of Russia, where he was famous for his red cape, flowing white beard, and bishop's mitre.

圣尼古拉成了俄罗斯人的守护神，在那里，他以身披红斗篷，留着飘逸的白胡须，戴着主教法冠而闻名。
