We assume that changes of azimuth antenna pointing between subswaths are small enough to guarantee that DC changes much tinier than PRF diversity.

算法假设子带间的方位向天线指向变化足够小，以致由此导致的多普勒中心的变化远小于PRF的差异，从而可以近似认为多普勒中心是随距离连续变化的。

In the high accuracy diffraction measurement of laser for a tiny wire,polarization direction of laser,laser beam property,and deviation of the beam center from the wire center have an effect on the measuring result.

在丝径的激光高精度衍射测量中，激光的偏振方向、光束的几何属性和光束中心对衍射体对称中心的偏离都会影响测量的结果。

Dealmaking in Dubai centres around The Gate, a cube-shaped structure at the heart of the Dubai International Financial Centre. A brainchild of the ruling al-Maktoum family, the DIFC is a tax-free zone for wholesale financial services. Firms licensed for it are not approved to serve the local financial market.

迪拜的金融交易集中于迪拜国际金融中心的The Gate大厦的总部中，作为马克吐姆家族的创造，迪拜国际金融中心是一个批发金融服务的免税区，但是该公司并未得到对于本地市场的服务许可。

The garden, which was slightly arched, had in its centre, on the summit of a hillock, a fine pointed and conical fir-tree, whence ran, as from the peaked boss of a shield, four grand alleys, and, ranged by twos in between the branchings of these, eight small ones, so that, if the enclosure had been circular, the geometrical plan of the alleys would have resembled a cross superposed on a wheel.

园里的地面是微微隆起的，中间有个稍高部分，一株美丽的圆锥形的枞树耸立在那上面，宛如圆盾中心的突刺，四条宽道从那中心出发，伸向四方，每一条宽道又都有两条小路，各向左右分展出去，各各相通，因此那片园地，假使是圆的话，那些道路所构成的几何图形就象一个加在轮子上面的十字架。

The sub-project named The impact of health risk on household income and consumption in rural area china started in the end of 2002.Owned to the MOA China, the workshop has completed the data entered and perceptivity works. Now the primary output is presented in 3 reports, this is 1st subject.1428 householdsand 8418 individuals are included by the survey, the main foundlings in this report includes: 1.the age time has come in China, their health problems should be recognition, in this sample the aged who is older than 65 have the incidence of a disease 36.1% in two weeks, and 36% can't get health care in

北京大学中国经济研究中心与农业部合作的课题题目&中国农村医疗保障制度建设&的子课题之一，&健康风险对中国农村地区家庭收入与消费的影响研究&，（课题主要负责人海闻教授，子课题负责人姚洋教授）自2002年末开始启动，在农业部农村发展研究中心的大力协助下，截至2003年6月完成全部问卷调查和数据录入及整理工作，现将初步的描述统计结果分为三个主题予以报告，本文为主题报告之一。

The formation mechanism of hailstones in the storm was analyzed too. The results show that the auto-conversion of frozen drops and graupels are the main sources of the hailstones in the strong convective storm studied in the paper, but the contribution of frozen drops is greater than that of graupels. Hailstones mainly depend on the processes of collecting supercooled water to grow.

同时模拟分析了冰雹形成的微物理过程，结果表明，本个例模拟雹云中，冰雹粒子主要由冻滴和霰转化形成，但冻滴对冰雹形成的贡献要比霰大得多，冰雹含水量中心的发展演变与冻滴含水量中心的发展演变相一致，冰雹主要是通过撞冻过冷水过程而进一步长大的。

In the "indirect" process, first observed in neutral kaon particles in 1964, quantum mechanics allows particles to change into their antiparticles and back again in a process known as "mixing". In 2001, The BaBar team, working at the Stanford Linear Accelerator -- and independently the Belle collaboration at the KEK laboratory in Japan -- were the first experiments to detect this in a B meson. BaBar observed "direct" CP violation in 2004 by showing that the number of decays observed for B mesons was higher than for their antiparticle equivalents.

在&间接&过程中，量子力学允许粒子在一种被称为&混合&的过程中，在自身与其反粒子之间相互转变。1964年人们第一次在中性K介子上观测到这种现象。2001年，在斯坦福直线加速器中心工作的BaBar研究组和另一个日本高能加速器研究中心的Belle研究小组各自独立地第一次在实验中观测到这种现象发生在B介子上。2004年，BaBar小组观测到了&直接&电荷宇称不守恒，他们发现观察到的B介子的衰变数量要高于其对应的反物质。

The first chapter briefly treats with the transformation of China social construction in the new period. The transformations mainly include two aspects: the political ideology being centralized transformed into the economical construction being centralized and the centralizing in culture became many-faceted.

第一章简略的阐述了新时期以来中国社会结构的转型，主要表现为两个方面：由政治意识形态中心向以经济建设为中心的转移以及由此而来的在文化上的一元向多元的转变。

The news of the trial's start made headlines in the country, and people were feeling "very numb," said Youk Chhang, head of the Documentation Center of Cambodia, where about 20 members of the public had gathered to watch the televised proceedings.

虽然审判开始的消息成为该国的报头新闻，然而人们对此的反应却相当麻木。柬埔寨档案中心的负责人Youk Chhang指出，。在该中心，大约有二十名民众在观看审判的现场直播。

The location of rockbody and orebody is controlled by the activity center of ore-bearing magma and ore pulp,among which the most critical controlling factor is the magma conduits connecting with the activity center of ore-bearing magma and ore pulp.

4岩体的定位受含矿岩浆、矿液活动中心的控制，而最关键的控制因素还是与岩浆、矿液活动中心相连接的岩浆通道的出口。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
