误差范围

Hence, the empirical productivity formulas for the gas wells of relatively homogenous and aeolotropic gas reservoirs were established with the "single point testing" method respectively.

但由于忽视了单点经验产能公式的适用范围和测试条件，计算的无阻流量与修正等时试井相比，部分气井误差达 30 %以上。

Focal error signal of pickup head is achieved according to the Astigmatical principle, and that the optical non-contact probe system with the measurement ranges of 2um and the measurement uncertainty of 1.1nm is obtained. This probe system is immune to the variation of reflective ratios and curvature on the surfaces of samples via improvement of the signal process method.

其中根据光学象散原理得到激光读取头的聚焦误差信号，从而获得测量范围为2μm，测量不确定度可达1.1nm的光学非接触探头系统，通过改进信号处理方式，此探头系统可不受材料表面反射率变化的影响，并允许样品表面存在一定的曲率变化。

They arecheap, interchangeable, have standard connectors and can measure awide range of temperatures.

便宜，可互换，标准连接器以及较大的温度测量范围主要的限制是精度，很难获得小于1°C 的系统误差。

The resulting CEbus standard, which the industry adopted in 1994 as EIA-600, targeted remote control, remote instrumentation, security systems, energy management, and entertainment coordination with other wiring that carried the entertainment content.

也正是因为噪音，电力线网络技术或者限制信号带宽，比如X10、SmartLab以及通用电力总线等标准和组织所做的尝试，或者采用复杂昂贵的噪音和误差消除技术，比如HomePlug AV标准，这些方案带来的后果就是没法大范围推广。

It is more serious especially under some special operating modes such as high temperature, corrosivity atmosphere etc.

当热电偶的热电特性变化超过规定的范围时，热电偶指示的温度便会失真，测温误差越来越大。

The laser granulometric analysis method can replace traditional methods due to its reliability. granulometric analysis ; correlation study ; the South Yellow Sea

沉析法适用于粒径小于0.063mm的物质，此法存在着检测速度慢、重复性差、对非球型粒子误差大、不适用于混合物料(即粒子比重必须一致才能较准确)、动态范围窄等缺

In conclusion, If the volume of the first step and second fermentation liquid were measured guarantee errors at 1% including, Aim at the current single canister to proceed the hypothesis that optimization combine control in time next, the tout a fait can be made present I the corporate and single canister produces the accumulation of the 2- keto - L- gulonic acid obtains to leading the level 84～ 86% of the period and can also be controlled at the same time within the sphere of efficient 36～40 h.

总之，在保证一步发酵醪液质量及二步发酵的体积误差在1%以内时，针对目前的单罐及时进行优化组合控制的前提下，完全可以使目前我公司的单罐产 2-酮基-L-古龙酸的积累达到领先水平84—86%。同时发酵周期也可以控制在最经济的36---40 h范围内。

In this paper, we construct the indiscernibility set of by defining the toleration relation on the continuous condition attribute and realize the partition of the universe by analyzing the decisions of the objects in the indiscernibility set of .

本文通过定义连续值域信息系统上系统误差允许范围内的相容关系，构造了对象的不可区分集。

The outputs from the ensemble simulation are analyzed using the three basic interpretational methods commonly used in the ensemble forecast; the consequence is that it is practicable to introduce ensemble technique in regional climate study. Th...

以集合预报的 3种基本释用方法，对集合模拟产生的大量输出结果作了细致的分析，发现在区域气候模拟中，引入物理集合是可行的；它为区域气候数值研究提供了更多的手段和信息；集合系统存在的不足之处在于：集合成员间离散程度不足、集合模拟范围较狭窄，这使得离差对误差的实际预报能力低于潜在预报能力，也使集合概率预报的精度降低。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
