查询词典 observational error

A commutation error is then considered in addition to the conventional residual error to generate the innovative residual error. Such an error is applied into cost functions to derive finite impulse response and infinite impulse response filter-based adaptive algorithms for ANC applications, referred to as FxRLS/CE and FuRLS/FRE+CE algorithms, respectively. Convergence analyses based on Lyapunov stability criteria for time-varying discrete-time systems can be carried out for the FxLMS/CE, FxRLS/CE and FuRLS/ FRE+CE algorithms to ensure stability. Computer simulations and experiments demonstrate that the innovative residual error-based adaptive algorithms can free the restriction of the slow-adaptation assumption in the conventional ANC approaches.

The monotony and extremum theory of function are applied to prove the geometrical characteristic of error hand for 2D linear segment uncertainty ε(subscript σ) model in theory. The result shows that the error hand has the geometrical shape of "larger ends and smaller middle" or "one end larger and the other smaller". The minimum width and its exact position of the error hand are calculated too. It is proved that the minimum width position of the error hand is near the end with the smaller mean square error.

运用函数单调性和极值理论，从理论上证明ε模型的误差带的几何特征；得到线元误差带不仅具有&两端大、中同小&，而且也可能具有&一端大、一端小&的几何形状；给出了误差带的最小带宽及其位置；论证了误差带的最小误差带宽的位置靠近中误差较小的一端。

The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.

拟合值和观测值吻合的较好，计算出的平均直径、均方根直径、均立方根直径和粒子浓度与观测值也比较吻合；本文对两组个例的催化影响区域及可能采集到相应值的下风方区域进行了分析，催化下风向影响区的F-100、2DC、2DP的粒子浓度比背景值都有所增加，但是增加的幅度不同，应该是催化响应时间的原因。

There exists extraordinarily affluent literature of historical earthquake.Currently,we inadequately utilize macro phenomena of earthquake and isoseismal,therefore,further explore the source of historical earthquake,and emphasize the uncertainty of epicenter and magnitude of historical earthquake.Since 1970,along with the advancement of observational technique, we greatly improve seismic observational accuracy,and moderate and small seismic data recorded by instrument is more and more sufficient.

历史地震的文献资料异常丰富，但是对地震宏观现象及等震线的利用显得不足，历史地震资源还待进一步开发；而且历史地震震中位置和震级的不确定性问题需要注意。1970年以来，由于观测技术的提高，地震观测精度得到很大程度地改善，仪器记录的中小地震资料也越来越丰富。

The observational equations have been derived using the three methods above which are based on high-low SST and low-low SST observational data respectively, at the same time, the shortages and merits of these three methods are analyzed. 3The problem of gravity field recovery can be attributed to the solution of over determined system of equations.

本文分别以高低卫卫跟踪和低低卫卫跟踪观测数据为基础，导出了基于上述三种方法的观测方程，并分析了它们的优缺点。3重力场恢复最终归结为超定线性方程组的求解问题。

The Erectile Dysfunction Observational Study is a 6-months observational prospective multicentric study enrolling men with erectile dysfunction who asked, to be started on a treatment or to change a previous treatment.

"勃起功能障碍观测研究"（Erectile Dysfunction Observational Study， EDOS）是一项为期6个月的多中心前瞻性研究，研究对象包括被要求开始接受治疗或改变治疗方式的ED病人。

The fast-detection technique for fault-gas Carbon Dioxide (CO 2) running o ut of active fault zones, the selecting and building of observational sites as w ell as the observational situation for fault-gas CO 2 in western Sichuan are introduce d in this parer.

介绍了快速测定活动断层带CO2 气体的方法、川西地区断层气CO2 观测点的选建以及观测的情况。初步的观测结果显示，在 1999年四川绵竹两次 5 0级地震、 2 0 0 1年四川雅江 5 0级和 6 0级地震和 2 0 0 1年云南永胜 6 0级地震前，部分观测点的断层气CO2 均有很好的短期前兆异常显示。

The junk rating is the percentage of the submitted message that was not useful (i.e., material that was not observational records, observational header or e-mail header). Many messages arrive with junk ratings of more than 50 percent (in some cases, more than 90 percent!). If you get a poor junk rating, you should examine what you are actually sending and try and cut out some of the junk that some PC mailers seem to insert.

用百分比表示，表示你上报的无用信息的多少（比如：非观测记录内容，非报告头或EMAIL文件头等）很多报告包括50%以上的垃圾信息（有些甚至超过90%），如果你发现你的上报有太多的垃圾，请自己检查你的报告，去掉不该添加的内容，有些邮件服务商会自动添加广告内容。

But this is impossible, as long as it is engaging in a market economy, there are risks in any operation.

但是，这是不可能的，只要是搞市场经济，是有风险的任何行动。

We're on the same wavelength.
