For small scale seismic facies volume, the seismic facies character change with traveltime is difficult to identify in time section, but they could be easily identified in timefrequency domain of Stransform.

通过对地震相特征的连续性以及振幅和频率变化特征的分析发现，对于规模较小的地震相体，在时间剖面上很难识别其层序内的地震相特征随旅行时的变化情况，但在S变换的时频域内可以被清楚地体现出来。

With the higher requirement of the low energy lost of hydrocyclone, especially single-level hydrocyclone inaccessible separation standard, industrialization requirements are carried out by series-parallel connection of multilevel hydrocyclone. Thus, the utilization of uniflow hydrocyclone becomes more and more abroad when the hydrocyclone changes its role from primary ultimate separation equipment to advance separation equipment.

随着对水力旋流器低能耗提出更高的要求，特别是单靠一级水力旋流器很难达到分离标准，需要通过多级水力旋流器串并联来实现工业化要求，水力旋流器从原来的终极分离设备变为预分离设备，这种角色的转变是直流式水力旋流器的应用日渐增多的重要原因。

Based on an analysis of professional feature, nature and the working environment, the paper indicates that the increasingly serious professional fatigue of faculty in universities are believed to be caused by uncontrollable teaching works, unreasonable internal management system and teachers' individual diatheses.

高校教师职业倦怠症日渐严重，通过对高校教师的工作特点、工作性质及工作环境的分析，指出教学工作的难控性、不合理的高校内部管理机制及教师个人因素是造成教师倦怠症发生的主要原因。

Noting with concern that effective management of marine capture fisheries has been made difficult in some areas by unreliable information and data caused by unreported and misreported fish catch and fishing effort and that this lack of accurate data contributes to overfishing in some areas, and therefore welcoming the adoption of the Strategy for Improving Information on Status and Trends of Capture Fisheries and the development of the Fishery Resources Monitoring System initiative by the Food and Agriculture Organization of the United Nations to improve knowledge and understanding of fishery status and trends

关切地注意到，由于鱼获量和捕捞作业的漏报或误报致使信息和数据不可靠，因此很难在有些地区有效地管理海洋捕捞业，且这种缺乏准确数据的情况造成一些地区捕捞过度，为此欣见联合国粮食及农业组织通过《改进有关捕捞业状况和趋势的信息的战略》和提出建立渔业资源监测系统的倡议，以便进一步认识和了解渔业的状况和趋势

Some essential trace elements were reported to be involved in the normal bone metabolism. Nowadays rare earth elements are widely used in many fields and more and more rare earth elements enter the environment and food chains They are enriched in bone and difficult to be excreted. Because the similarity between rare earth ions (Ln3+) and Ca2+, they will intervene and regulate bone formation and remodeling.

骨骼的正常代谢涉及多种金属离子，随着稀土的应用，通过环境和经由食物链等渠道进入人体内的稀土量也有所增加，并且在骨组织中相对富集且难排出；由于稀土与钙离子的相似性，它们将干预和调控骨的形成与再造。

One day after a hard rain, my friend and I decided a foot race through my dad's then empty, but very muddy, garden patch would be a great idea.

有一天，下雨后很难，我的朋友和我决定一英尺的比赛，通过我的父亲当时的空白，而且非常泥泞，花园补丁将是一个伟大的想法。

Now, in recent years, beside of many kinds of anti-osteoporosis drugs to treat this kind of disease, also many doctors use some tiny-trauma ways to treat it, such as vertebroplasty which use needle punch through pedicles and inject bone cement into compressed vertebras, and kyphoplasty which use a balloon to lift the compressed vertebras.

目前对于中老年骨质疏松性胸腰椎椎体压缩性骨折的治疗，除了相应的抗骨质疏松药物治疗以外，近年来国内外应用微创的办法通过椎弓根穿刺注射骨水泥对难治性疼痛性胸腰椎压缩骨折进行治疗即所谓的椎体成形术2和气囊扩张后的后凸成形术3。

It is hard, though, to see a parent's evolutionary interest in controlling its offspring's lifespan by making some somas more disposable than others—nor why evolution would favour longevity in the children of older parents.

然而，很难理解父母的进化取向是通过制造一些比其它体细胞更脆弱的体细胞来控制后代的寿命，同样也不能理解为什么进化中的长寿会钟情于大龄父母的孩子。

Considering the low efficiency of current Web services processing,the paper suggests that the demands of requesters be represented as Service Template in forms of constraint by adding ample semantic description to Web services,and then ST is matched with Service Advertisements which have been published and saved in enhanced UDDI library,so we can get a set of candidate services,at last,we can find an optimal service from this set.

1引言目前，各个公司和研究机构都在寻求比较优化的Web服务处理的方案，由于这些方案缺乏对服务语义的详尽描述，这样在服务处理过程中可能导致下列问题：(1)在Web服务处理过程中，不得不通过静态绑定Web服务来完成相应的业务处理；(2)很难改变现存的设置以便协调新的Web服务处理；3

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
