两三个

Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable and three parts which are still under development.

任何电路设计都得包括至少一个废用部分，两个用不上的部分以及三个仍未完成的部分。

The present paper falls within the scope of three historical phases, Japanese Colonial Period, Post-hostilities Period and contemporary relevance; it takes diachronic Luan-tan Opera audio materials in the same play for the research theme, cuts into the angle with vernacularism, attempts to observe the varieties of language changing while these troupes were trying to fit in the environment.

本论文以日治、战后及当代三个历史段落为范围，选择跨越两个时空以上、相同剧目的乱弹戏有声资料为研究题材，并以戏曲剧种的白字化为切入视角，试图观照戏曲剧种适应环境所因应的变异性，即「剧种语言」在地化的现象。

Women also have three such vertebrae, while men have just two.

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.

本项目立足于从火山岩属性和深源捕掳体反演源区成分与结构两个途径，利用火山岩综合研究成果对地幔源区进行了初步反演，提出源区经受过强烈钾质交代的观点；对重点工作区TM图像进行了初步解译，新发现若干了火山口，并对其中三个火山口作了实地查验，为进一步全面深入开展该区的火山地质学及相关科学问题打下了良好基础，认为托云盆地是一个火山群，而不是一个单一的火山构造盆地；系统测制了火山岩剖面，新采集了一批重要的火山岩和深源岩石捕虏体样品，为下一步工作打下基础，特别是采集到了直径打20cm的幔源橄榄岩包体，可用于各种测试，将可以结束西部造山带没有地幔岩化学分析结果的历史；对康西瓦玄武岩进行了测年分析，取得了我国目前最年轻的锆石U-Pb SHRIMP年龄，对青藏高原挽近地质时期的隆升提供了年代学约束；对帕米尔东缘塔什库尔干碱性岩体的动力学意义进行了探讨，提出青藏高原西部构造结的形成与岩浆活动有关的观点。

You could go back perhaps, he hasarded, still thinking of the very unpleasant scene at Westland Row terminus when it was perfectly evident that the other two, Mulligan, that is, and that English tourist friend of his, who eventually euchred their third companion, were patently trying as if the whole bally station belonged to them to give Stephen the slip in the confusion, which they did.

你也许可以回家去。他委婉地说，心里却仍回顾着在韦斯特兰终点站的不愉快场面：另外两个家伙--即穆利根和他那英国旅伴，就好像那座讨厌的车站属于他们似的，显然试图趁乱把斯蒂芬甩掉，并终于让他们的第三个伙伴上了当。

Two of the three EAMT devices are mockups of aircraft hardware: One represents the gun bay and pallet, and the other a wingtip pod.

三个EAMT设备中的两个是飞机硬件的仿制品：一个代表枪炮和托盘，另一个代表飞机翼尖吊舱。

Second type of FL~Z〓 curve is set up for those specimens which were not ground after peening.

在三个阶段之间有两个临界点，它们可以根据本文提出的"10~20D准则"确定。

In this paper treated three species of genus Caloplaca described from Altun mountain were first reported to China.C.ignea and C.trachyphylla have orange or reddish orange lobed thallus,the lichen substance mainly anthraquinones and the other species C.oblogula thallus usually invisible,gray ,apothecia black,and it has not contain any anthraquinones .

本文中所阐述的三个种，于2005年阿不都拉。阿巴斯教授对阿尔金山自然保护区地衣和其它生物结皮调查时所采集的。Caloplaca ignea 和Caloplaca trachyphylla 这两个种的地衣体是橙色或橙黄色的边缘深裂的裂片状地衣体，而Caloplaca oblogula 的地衣体灰色或生长在岩石内，子囊盘是黑色。

In these three manuscripts the painting has an anecdotic character; it is intended to illustrate the text, and sometimes two periods of a scene are represented in a picture.

在这三个手稿画中有一个anecdotic性质，它是企图说明文，有时两个时期的一个镜头代表合影。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
