大小相当的

A series homopolyme of ethylene synthesised by metallocene catalyst was analyzed by the high temperature gelatin permeation chromatography. The results showed that the molecular weight distribution changed not too much when the ratio of Al/Ti ranging between 1000 and 4000, while the molecular weight distributed increased from 2.48 to 2.81 when the ratio ranging between 4000 and 7000; catalyst D had the lowest activity to be used as asymmetric metallocene catalyst; the curve of molecular weight moved much to the left with the increases of temperature and two active centres appeared when the temperature is 70℃.

通过高温凝胶渗透色谱对茂金属催化合成的一系列乙烯均聚物进行了分析，可以看出Al/Ti比从1000变到4000时，分子量分布曲线图变化不大，而从4000变到7000时，变化相当大，分布宽度从2.48增至2.81；催化剂D的活性最小，可作为非对称性茂系金属催化剂；该聚合体系分子量的大小受聚合温度的影响很明显，随温度的升高，分子量分布曲线图向左发生很大位移，在聚合温度为70℃时存在两个活性相当的活性中心。

In this paper, the FIR low-pass digital filtering method is first introduced for reducing the effects of noise signals in the experiment of velocity measurement of high-temperature flue gas flowing in pipe. The experimental results indicated that, only one peak presents in the cross-correlation graph, which is in good agreement with theoretical analysis result. Secondly, the temperature and pressure pulse signals of the high-temperature flue gas, obtained by thermocouple and pressure sensor, are introduced to explain the applicability of sensor characteristics.

本文介绍在测量管内流动的高温烟气流速的实验中采用FIR低通数字滤波器滤波方法可以排除干扰信号的影响的研究，实验结果证明，经过滤波处理后的信号互相关函数的图形不会出现大小相当的多个峰值，符合理论分析的结果；其次，本文还介绍了用热电偶和压力传感器采集的烟气温度和压力脉动信号，分析了传感器特性对相关测速的适应性。

Please note that our sample size was rather small, therefore the standard deviation could be quite large.

请注意我们的样本大小相当小，因此标准偏差能是相当大的。

Although existing transmitter is quite large in size, about the size of a suitcase, but it is foresee that the size can be shrunk down as small as a cigarette pack, making the proximity attack possible anywhere without the users' acknowledgment.

虽然现有的发射机是相当大的规模，大小相当于一个手提箱，但它是预见到的规模可缩小下跌的一小部分卷烟包装，使尽可能接近攻击没有任何用户的认可。

All well and good, except that Virgin's proposed business-class-only service to New York from Amsterdam, Frankfurt, London, Milan, Paris and Zurich runs counter to this idealism. Branson has been quoted as saying that he may use Boeing 787 Dreamliners for this, an aircraft designed to accommodate up to 330 seats (and use 20 per cent less fuel than other aircraft of that size). Yet he would need to carry fewer than half this amount if the Virgin service is to compete with, say, Silverjet, whose 767s have been adapted to accommodate 100 (compared with 252 on a regular aircraft of that type). Perhaps those flatbeds aren't so comfortable after all.

好倒是好，只可惜维珍航空提议的从纽约到阿姆斯特丹、法兰克福、伦敦、米兰、巴黎和苏黎士的商务舱专用服务，与其理想完全背道而驰布兰信曾说可能为此使用波音787梦幻客机，该机设计载客量为330座（与其大小相当的其它飞机相比，燃料消耗可节省20%）如果维珍航空服务与Silverjet竞争，他就需搭载不到一半的乘客Silverjet的767客机已经过改装，容纳100人（同型普通飞机可容纳252人）大概平板车确实不太舒服吧！

In most species they are composed of roughly equal amounts of protein and ribosomal RNA , the ribosome consists of two unequally sized rounded subunits arranged on top of each other like a cottage loaf, eukaryotic cells have larger ribosomes than prokaryotic cells but the ribosomes in mitochondria and chloroplasts are about the same size as prokaryotic ribosomes.

在大多数的物种中，蛋白质的量和 rRNA 量是大体相等的。核糖体包括两个大小不同的亚单位，上部结合形成小屋状结构。真核生物细胞中的核糖体要比原核细胞的核糖体大，但是线粒体和叶绿体中的核糖体与原核细胞的核糖体大小相当。
