It was shown that the SNR of the RADS could be improved by using a microwave cavity with proper microwave field mode and high microwave filling factor, a rubidium spectrum lamp with high spectrum purity and a separated isotope filtering scheme in the physics package design. The performance of the rubidium atomic frequency standard could be improved by taking all these factors into consideration.

本文分析了微波腔的结构、铷光谱灯的光谱纯度和同位素滤光方案对信噪比的影响，指出采用模式优越、微波填充因子大的微波腔，光谱纯度高的铷光谱灯，用分离滤光方法进行同位素滤光，可以提高铷原子鉴频信号的信噪比，从而使铷频标的稳定度指标得到进一步改善。

Hydroquinone-formaldehyde organic aerogels with high HC ratio (10~40, molar ratio of hydroquinone to catalyst) have been prepared using sol-gel process. And carbon aerogels have been prepared by pyrolyzing the aerogels.

溶胶－凝胶法制备了高HC比（10~40，对苯二酚与催化剂(Na2CO3)的物质的量之比）的对苯二酚－甲醛有机气凝胶，并经高温碳化处理得到其碳气凝胶。

PGE analyses for the picrites of the middle Devonian Beitashan Formation at the south margin of Altai Mountains show that the PGE concentrations are within a narrow range, and their primitive mantle normalized PGE patterns resemble those from Grenada picrites, Lesser Antilles Arc in Atlantic, which is characterized by the enrichment of PPGE although the PGE contents of the researched picrites are higher than the latter, and lower than those from large igneous provinces.

本研究对新疆阿尔泰山南缘中泥盆世北塔山组地层中的苦橄岩的铂族元素进行了分析，结果表明：其铂族元素的含量总体变化不大，其原始地幔标准化曲线总体上和已经报道的大西洋Lesser Antilles岛弧的Grenada苦橄岩相似，均以富集把组铂族元素为特征，但总体含量比后者高，而比大火成岩省的苦橄岩低。

The ostinato hi-hat on Pat Metheny's "Last Train Home," from his Still Life (Geffen 24245-2), was also balanced more forward in the mix than I expected, and sounded more metallic than usual.

在固定音型高科技帽子麦塔尼的&末班车家&，从他的静物（格芬24245-2），也更具前瞻性的平衡混合比我的预期，听起来比平常多金属。

The high count for this winter may be due to:(1) more sites were covered;(2) better trained participants, most of whom have received two trainings;(3) better equipment and bird field guidebooks.

本次调查数量比上次调查数量高的原因可能是：(1)本次调查比上次增加了5个地点；(2)很多的调查人员已经经过了两次培训，鸟类方面的知识和技术提高了；（3）我们为所有调查点提供了《中国鸟类野外手册》，又配备了更多的望远镜，增加了水禽识别和计数的精确性。

Ventilate computer rooms regularly. Install ventilating fan or air conditioner to mitigate the effect of polybrominated dibenzofuran on the body. The dust density around computers is hundreds of times higher than other spaces in the computer room. The dust long adheres to the skin and thus causes various skin diseases.

电脑房间要经常通风，在室内安装换气扇或空调，减轻溴比二苯呋喃对身体的影响，计算机附近的灰尘密度要比机房其它空间高出上百倍，它们长时间附着于人的皮肤上，可导致各类皮肤病。

Because town dweller is having higher than rural dweller income level, it is important to make the change of quality of the product in town wants to compare a country much.

由于城镇居民有着比农村居民更高的收入水平，使城镇中产品质量的改变要比农村重要得多。

Greenhouse pot tests showed that treatments with GJ23,NJ08 and NJ28 have greatly inhibited gall formation on tomato roots.

用GJ23，NJ08和NJ218的菌悬液进行的温室盆钵实验，结果表明不同的浓度处理均对番茄上南方根结线虫的根结形成有显著的抑制作用，其中2倍菌液处理的平均根结数比对照分别少51.4%、62.5%和54.5%；它们还对番茄的生长有明显促进作用，2倍稀释菌液处理组的番茄冠重分别比对照高39.8%、32.0%和60.5%。

This paper presents design and experimental resultsfor a high performance single stage transonic fan with design pressureratio 2.3 and design efficiency 0.88 at high tip speed 510m/s (relativeMach number reaches 1.72) and low aspect ratio.

本文介绍一高性能单级跨音速风扇的设计与试验结果。该风扇设计压比2.3，设计效率0.88，具有高切线速度510 m/s(相对马赫数达1.72)和低展弦比。

During the New Moon (the 1st of a lunar month) and the Full Moon (the 15th of a lunar month) when the Earth, Moon, and Sun lie in a straight line, the solar and the lunar tides overlap and the sea-level pressure is lower than the mean at the Airport, because the tide-producing force induced by the Sun and Moon reaches maximum. On the other hand, during the First Quarter (the 7th day of a lunar month) and the Last Quarter (the 21st of a lunar month) the Sun-Earth's and the Moon-Earth's relative positions are perpendicular to each other with respect to Earth, the solar and the lunar tides interfere mutually, the Airport sea-level pressure is greater than the annual mean due to the tide-producing force reaching minimum.

松山机场在朔望月里，每逢阴历朔日或望日，受太阳与月球之引潮力(Tide-producing force)方向一致，太阳潮和太阴潮重叠影响，其全日和逐时平均海平面气压比年平均为低；而每逢上弦和下弦时，日地与月地的相对位置成直角，太阴潮和太阳潮相干扰，其全日和逐时平均海平面气压则比全年平均为高。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
