Simulation results show that the beampattern of the concentric-ring array has lower sidelobe level compared with the circular array, and is effective in formation of adaptive nulling as well.

仿真结果表明，与均匀圆阵相比，双层圆阵的波束图有较低的副瓣电平，而且能够形成较深的自适应零点。

Processing means (36) identify patterns of dark pixels in the array as trash, neps, seed coat neps, and other impurities in the fiber by comparing the patterns of pixels in the array with patterns in a lookup table.

通过把阵列中的像素的图案与一个查阅表中的图案作比较，处理装置（36）把阵列中的暗像素的图案鉴别为纤维中的杂质，纱结，种子外层纱结，和其它杂质。

By means of these conditions, computer searches out many quasi-perfect and double quasi-perfect binary array pairs with small sizes. The composite construction methods for quasi-perfect and double quasi-perfect binary array pairs are studied.

By means of these conditions, computer searches out many quasi-perfect and double quasi-perfect binary array pairs with small sizes. The composite construction methods for quasi-perfect and double quasi-perfect binary array pairs are studied.

本文较为详细地分析综述了几十年来，最佳相关信号的研究成果，它已在现代通信、雷达、声纳、制导、空间测控、以及电子对抗等方面得到了广泛地应用，为工程应用提供更多具有良好相关特性的最佳离散信号是研究最佳离散信号的目的之一。

Considering there are four output channels in the CCD, the diamond linear array model is replaced with a new two-angle tree linear array in order to improve the performance of the wave-front processor. This change was successfully proved in the 127-element Adaptive optical system and a speed up near the theory limitation is achieved also.

本文第六章利用菱形线性阵列结构设计了波前处理机的硬件平台，并针对光电探测器多通道输出的特点，将菱形线性阵列改进成二叉树线性阵列并成功运用在127单元自适应光学系统中，取得了接近理论极限的加速比。

In Direct3D 10, adjacent stages effectively share a register array, where the upstream stage writes data to specific locations in the register array and the downstream stage must read from the same locations.

在D3D10中，邻接的流水线阶段可以有效的分享寄存器数组，前一个阶段把数据写入寄存器数组特定的位置，后一阶段从相同的位置读取。

Since they deal in pointers, not array indices, no other routine need know the name of the array, which can be declared static in the source file containing alloc and afree, and thus be invisible outside it.

由于函数alloc和afree处理的对象是指针而不是数组下标，因此，其他函数无需知道该数组的名字，这样，可以在包含alloc和afree的源文件中将该数组声明为static类型，使得它对外不可见。

The main work and the results are as follows: 1、 This paper introduces the characteristic, predominance, development of high intensity focused ultrasound, especially in phased-array systems. Surrounding with the phased-array system, different sorts of applicators, different distribution of elements and the main calculate methods are presented.

论文的主要工作和相关结果如下： 1、首先介绍了HIFU技术的特点、优势和发展历史以及相控阵HIFU的原理和优势，并根据本文所涉及到的内容，简单介绍了相控HIFU源的分类，阵列设计以及目前主要用的计算方法。

The second is a string array that holds the same length as the ASCII array.

第二个是一个字符串数组作为持有相同的ASCII数组的长度。

Firstly, in contrast to the dipole resonator, the folded dipole resonator is used to improve the frequency responses. Secondly, two types of folded Yagi-Uda arrays are fabricated, one is the original array with uniform length and spacing, the other is the optimum array with perturbed length and spacing to obtain a higher directivity gain.

首先，应用摺叠式耦极谐振器取代原有耦极谐振器以改善频响应，接著设计组摺叠式Yagi-Uda阵天线，一是保持均匀长与间距的初始阵，一是微调长与间距的优化阵，以得到较高的方向增。

"The operators will suffer a temporary decrease in the number of consumers and short message services as people may not like having to provide their ID cards for a phone number," Xu Junqi, vice-dean with the Policy-Making Institute of the Telecommunications Research Centre under MII, said yesterday.

信息产业部下属的通信决策研究院副主任徐俊其昨天说：&实行手机实名制后，人们可能不太情愿用身份证注册手机号，所以通信运营商会暂时面临用户减少和短信用户减少的问题。&

I don't believe in make-believe!

我不相信这些虚构的故事。
