操作误差

Neuronavigation can offer accurate location and measure . 2. 4 spaces of sellar area could be viewed and controlled satisfied via supraorbital keyhole approach .

结果：1、导航系统的实时定位功能非常好，误差较小，在测量过程中具有良好的持续准确性，本实验颅内的测量结果可靠。2、眶上&锁孔&入路可以通过鞍区常用的四个手术间隙到达靶区进行手术，对Willis环相关血管的显露和操作空间良好。

The result suggests that weight method is imprecise and unrecurrent though simple and easy to operate.

实验发现称重法等虽简单易行，可实验误差大、可重复性差，所以本文引入了图像处理方法来测试编织型神经导管的孔隙率，在测量方便、操作简单外，还具有较好的可重现性。

The Results shewed that there is the highest absorbance at 492 nm,and the standard recovery rates high,and the relative error small,and the recurrences good,and this method is simple and suitable for all kinds of defatted coffee grounds.

结果表明：它在492 nm 处有最大吸收峰，测定标准回收率高，相对误差小，重现性好。该法操作简单，效果良好，适用于测定各种类型脱脂咖啡渣中甘露聚糖的含量。

And used the MATLAB realizationnumerical integration analysis, the experimental result had alsoproven had the operation simply using the MATLAB realizationelectromagnetic field numerical integration analysis bright, theoperating speed has been quick, miscounts slightly and so on themerit.

并利用MATLAB实现数值积分分析，实验结果也证明了运用MATLAB实现电磁场数值积分分析具有操作简单明了、运算速度快、计算误差小等优点。

Sample preparation especially the extraction of chemical components from medicinal plants is of the most time consuming, tedious a...

在药用植物的化学成分分析方面，样品的预处理尤其是化学成分的萃取依然是整个分析过程中操作最烦琐、最耗费时间也最易引入误差的一个环节。

According to the structural feature of modern tilting levels, the method of erecting the collimation axis to the standing axis and the principle of the setting out of slope with the tilting standing axis are expounded.

根据现代微倾水准仪的视准轴可以调整的构造特点，阐述了使水准仪视准轴垂直于竖轴的方法，以及倾斜竖轴法放样斜坡面的原理；讨论了其误差来源、大小；对照几个行业的设计、施工及验收规范和测量规范，给出了简便可行的操作方法与有效检验手段。

Apparatus driven by a stepper motor measuring bar mobile, no operator launches, to abandon completely the work of hand spinning forward, manual on line, the estimated time error, manual record, collate test results of the artificial manner of operation.

仪器由步进电机带动测杆移动，不用操作手轮，工作时完全摈弃手旋推进、手动对线、估读误差、手工记录、人工整理检定结果的操作方式。

For example, size problem to offsctdruckereien point of view, the greater the number of celebrity…, the better, because the same set of products can be more, and flexography is not, efficiency depends on the machine speed, in parts of the appropriate size, size 小意 to use low-cost, small size, from roll to die-drum is plate, tape, seihan fees naturally had; size also means that the cumulative operation error gets smaller, quality control is easy.

譬如尺寸问题，以胶印的观点则是开数越大越好，因为同样印数下可以多出产品，而柔版则不然，效率是靠机速实现的，在活件允许的情况下，尺寸适当即可，尺寸小意着使用成本低，试想，尺寸小则从版辊到模切滚筒都小，版材、胶带、制版费自然也就都省了；尺寸小还意味着操作过程中的累计误差变小，质量控制也就容易了。

A low complexity detection scheme for the MIMO system with distributed transmit antennas is presented. Based on a Sorted CHolesky Decomposition, the additive gaussian color noise after match filter is whitened; The detection sequence according to the post signal noise ratio is reordered, and the risk of error propagation is degraded. The whole algorithm only requires one matrix inverse.

摘要针对发射天线分布的MIMO信号，基于排序的乔列斯基分解过程(Sorted CHolesky Decomposition，SCHD)，将匹配滤波后的加性高斯色噪声转化成加性高斯白噪声，根据后验信噪比对发射信号检测顺序进行重排，降低了误差传播的影响，该算法仅需一次矩阵求逆操作。

Previous analysis of associated gas had the disadvantages of complicated operation, being strenuous, timeconsuming and prone to errors due to the backward in chromatographic column and analyzer, as well as the limitations of separation and detection methods.

早期由于色谱柱及分析仪器比较落后以及分离、检测手段的局限，油田气的组分分析操作烦琐、费力、费时且易产生误差。

Plunder melds and run with this jewel!
