最大误差

The frequency fluctuation of the stabilized laser is held within 5.6 MHz and better than 160 MHz of the free-running laser. The root of Allan variance of error signals reaches a minimum of 1.66×10 -11 when averaging time is 64 s, well within the precision needed for application.

稳定后的激光频率波动小于5.6MHz，相对于自由运转时的160MHz有了很大提高，而误差信号的Allan方差均方根在平均积分时间为64s时达到最小值1.66×10-11。

There exist many literatures concerning the research that the biased estimators with certain restricted conditions outperform the least squares estimator under the criterion of the mean-square error.

2在均方误差准则下，满足一定约束条件的有偏估计优于最小二乘估计的研究相当多，在Pitman准则下的类似研究存在比较大的困难。

During the mensuration and the caculation of the minimum ignition energy, involved the excessive error in the traditional way and the more precise method of determination and computing have come up with.

在最小点火能的测定和计算中，分析了传统方法中存在的误差过大的弊端，并提出了更为合理精确的测定、计算方法。

In one mission flight, the Global hawk can proceed extension area radar search and EO/IR photo capturing for 74,000 square kilometers, the minium CEP of the target positioning would be 20 meters.

一次任务飞行中，"全球鹰"既可进行大范围雷达搜索，又可提供7.4万平方千米范围内的光电/红外图像，目标定位的圆误差概率最小可达20米。

Combined with the characteristic that biomass can vary in a wide range, the error function of the traditional BP network is improved. Meanwhile, optimal stopping rule is used to avoid over-fitting.

结合菌体浓度变化范围大这一特点，将传统BP网络的误差函数进行了改进，并利用最优停止法对网络进行训练，避免了过拟合现象。

Four testing methods to detect the pollen viability of cucumber were being compared. The results indicated that I-KI staining method and acetic red dyeing were not suitable to judge the pollen viability of cucumber. Tetrazolium method can be used but the error is oversize. By and large, the Germination in vitro method was an efficient, stable and simple way to judge the pollen viability of cucumber. The component of culture medium is 10% sucrose+ 100mg/L H_3BO_3. If inoculated intraday, collect pollen of fresh abloom flower at 6:00 and if inoculated at the second day, collect before dark.

比较了4种常用的花粉活力测定方法——I-KI染色法、醋酸洋红染色法、TTC染色法和离体萌发法，认为I-KI染色法和醋酸洋红染色法不适于测定黄瓜花粉生活力，TTC染色法虽适用但误差较大，综合考虑各项因素，确定离体萌发法是最准确、简便、稳定的测定黄瓜花粉活力的方法。

For the Hopfield network in solving the traveling salesman problem offen getting unvalid and not optimal solution, this paper introduced a suitable radom initialization of the output values Vxi of permutation matrix to guarantee an effective solution, used the error produced by taking a larger step size and required new solution to be better than or equal to old solution so that the final result can jump out local minima to find the global optimal solution.

摘 要：针对Hopfield网络解旅行商问题经常出现无效解和局部优化解，本文给出置换矩阵的满足一定条件的元素Vxi作为初始值，以便得到有效解。此外，还利用较大的步长所产生的误差和对当前解必须优于或等于已有解的要求，使计算结果能从局部优化解达到全局最优解。

We modeled the triplicated P waveform to determine the focal depth relative to the 670 km discontinuity and found that the earthquake actually occurred above the discontinuity. Thus even the deepest earthquakes in current catalogs still occur in the upper mantle.

因为地球中的横向不均匀性，地震的绝对深度有较大的误差，所以我们根据观测地震图中明显的三重值特征，对上述那次深地震进行波形模拟，把相对深度和绝对深度结合起来，最终确定地震实际发生在670公里间断面以上，因此我们认为目前目录中那些最深的地震仍然发生在上地幔中。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
