In this report, the author analyzes the impacts of that error, discuss on remedy for exact derivative-free noncircular fan-beam reconstruction, and pose some open questions.

在本文中，作者分析了该错误的影响，讨论了用于非圆轨迹不含导数的精确扇束重建的矫正办法，并提出了一些未解决问题。

If utilitarianism is wron9, a proponent of economic analysis has a choice : He or she can either abandon the normative use of the Pareto criteria in favor of a nonutility — based efficiency criterion or try to construct nonuti1itarian normative arguments for the Pareto criteria ...

如果功利主义是错误的，那么经济学分析的支持者就有了一个选择：即或是为了非效用基础效率标准，他或她可以抛弃帕累托标准的规范用途，或是为了帕累托规范构建非功利主义规范的观点。

This application is advantageous in analyzing error in phase retardance measurements.

在分析相位延迟量的测量错误时，这个应用也是很有价值的。

It is important to realize that DO-178B/ED-12B not only states that dead code "should be removed": Section 6.4.4.3c continues with the statement that "an analysis performed to assess the effect and the need for reverification."

由此可见，死代码处理包括两件事，一是消除，二是分析，必要时还要做第三件事——重新验证。虽然标题里说&深入理解&，但这只是一种愿望，文章内容未必有深度，或许还有错误。敬请DO-178B加油站网友指正。

The issues of present seismic wavelet frequency caused by different concepts, such as apparent frequency, dominant frequency, peak frequency and centroid frequency, etc., which are defined by different methods, and understanding deviation, definition of seismic wavelet frequency for time and frequency domain are concluded and summarized. On this basis, three kinds of seismic wavelets in common use such as Ricker and Zinc wavelets as well as sine wavelet with exponential attenuation characteristics are analyzed and a conclude is achieved that apparent frequency and dominant frequency are consistent in essence, but peak frequency and centroid frequency as well as apparent frequency or dominant frequency are not completely consistent with different seismic wavelets. For actual seismic data, peak frequency can approximately be used as dominant frequency, but it is not suitable when seismic wavelet is known for it can give out any wrong knowledge and results.

针对目前地震子波频率由于定义方式出现的各种概念（视频率、主频、峰值频率、中心频率等）以及理解上出现的偏差等问题，首先从时间域定义和频率域定义2个方面进行了归纳和总结，并在此基础上对3种常用地震子波（Ricker子波，Zinc子波，正弦指数衰减子波）进行了分析和研究，得出视频率与主频概念一致，但不同地震子波的峰值频率、中心频率和视频率之间并不完全一致的结论；而对于实际地震资料，将峰值频率近似看作地震子波的主频是可以的，但在地震子波已知的情形下这样做是不恰当的，甚至可能会得出错误的结论和认识。

this paper analyses the basic principle of tpc,compares the error performance in the system which has been applied with tpc with the uncoded system,studies the influences which different block codes and iterative numbers to tpc decode performance.under the circumstances of different iteration numbers and block codes,experiment simulation is carried on.the simulation results indicate that introduction of tpc can get the code gain of 5~6 db.tpc decoding algorithm is simple,and doesn′t have the error floor,the complexity of its hardware implementation is smaller,it is a kind of practical channel coding method.

摘 要：在分析turbo 乘积码的基本编译码原理的基础上，比较了未编码与编码后系统的差错性能，研究了选取不同分量码、不同迭代次数对tpc译码性能的影响。在不同迭代次数与分量码情况下，进行了仿真实验。仿真实验表明，在相同的差错性能条件下，采用tpc码能带来5~6 db的编码增益。tpc译码算法简单，没有错误平层，硬件实现复杂度较小，是一种非常实用的信道编码方式。

Some case analyses indicate that application of extended synchronization sequences can solve this kind of limitation effectively, and the unsynchronized event errors and incorrect synchronization errors can also be detected effectively in java multithreaded programs.

实例分析表明，同步扩展同步序列的应用，能够有效地解决上述局限性，Java多线程程序中事件未同步及其引起的同步不当等错误也能得到有效的检测。

Moreover, problem sources of collocation errors include transliteration, coinage, approximation, overgeneralization, use of synonyms, ignorance of rule restrictions, use of de-lexicalized verbs and verbification.

第二，若是以搭配字词来做分析，研究发现有八项常见的错误原因出现在此研究之中，分别为直译、创新字、概略原则、过度推论、忽略语法限制、非词汇动词(de-lexicalized verbs)以及动词化。

And if it cannot spot the real target, it is developing interceptors with multiple "kill vehicles" to destroy decoys too.

但是如果分析错误的话，那么携带有多重&毁灭方案&的拦截导弹也会摧毁诱饵。

To investigate the inhibitory patch of nickel, we analyzed intermediates of limiting repair reaction by denaturing gel electrophoresis.

所以为了进一步探讨镍抑制人类核酸配对错误修复系统的路径，我们利用了碱性琼脂凝胶分析修复反应的中间产物。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
