ConclusionThe causes,clinical appearance of gerontism acute bowel obstruction are specific,with more complications,worse prognosis,and clinical doctors should pay attention to it.

老年性肠梗阻在其病因、临床表现上有其特殊性，且合并症、并发症多、预后差，应引起临床医生的重视。

For Poul Nielsen the gestural mark is based more comprehensively in a personal exploration of western expressive abstraction.

对保罗而言这样的艺术更多是基于他个人对西方表现抽象的理解与探索。

An additivedominant model are fitted only to fibre length and ginned rate in inference of genetic model among the fibre length,micron,yield of unginned cotton,weight per boll,ginned rate and seed index.The fibre length is part dominant and the gene controlling long fibre is both recessive and dominant.

纤维长度为部分显性，长绒基因既有隐性，也有显性，广义遗传力为7817％，狭义遗传力为6744％；衣分率广义遗传力和狭义遗传力分别只有2608％和2116％，高衣分率基因较多的表现为隐性。

The actuality of combination of farming and graziery incarnates the differences of two production systems, agriculture and stock raising, in aspects of input and output, absorbing labour force and intensity acting on environment, which is result of confliction and balance of human and environment. Of course this balance did not consider the environmental cost and ecological risk, and land degradation is the problem of this selection.

科尔沁沙地农牧交错的现状体现着农、牧业两种生产系统的投入产出差异、对劳动力消纳能力以及对土地作用强度的多相矛盾，是人地矛盾协调与平衡的结果，是&人尽其责，地尽其用&追求最大效应的选择结果，当然这种选择是没有考虑环境成本与生态风险，而土地退化就是这种选择对生态环境影响的重要表现形式。

The journey and the new life for migrants were often grindingly harsh, as many exoduses were illegal and dangerous, but that obviously didn't stop the waves of people going abroad.

显然，从旅途到居留地，伴随着新移民的更多的是艰辛和磨难，但中国人的出国潮依然一浪高于一浪，甚至不时以畸形形式表现出来。

The clinical features of PCAA included: forming giant aneurysm in about 80% cases; presenting SAH and induciag focal symptoms e. g. hemiparalysis, paralysis of oculomotor or hemianopsia; showing massive lesion around cerebral peduncule or internal temporal lobe on CT scan; being associated with a fetal PCA.

PCAA的临床特点是：(1)易形成巨大动脉瘤，约占80％；(2)临床表现以SAH最多见，且也常有局灶性症状，如偏瘫，动眼神经麻痹、同向偏盲等；(3)CT检查常可见大脑脚旁或颞叶内侧占位病变；(4)常伴有胎儿型PCA。

Viewed historically, cultural modernization is featured by a fuzziness in its objectives, a hereditariness in its approaches, an adaptability in its nature and a plurality in its way of expression.

而现代化则必须与时间紧密结合才有意义，它特指最近时期所出现的发展及其成果，特别是成果。更为重要的是，发展更多地表现为一种客观现象，是人

The heterogeneously sulfonation products not only own the properties of reacting promptly and high sulfonation degree, but also have good performance in decreasing interface tension and tolerance to calcium ion.

多相磺化产品不仅有反应迅速、磺化度高的特点，在降低界面张力及对钙离子的容忍能力方面亦有不俗的表现，充分说明改变反应体系是具有巨大实用意义的。

Rep-PCR method was used to conduct cluster analysis to the 39 bacterial isolates. rep-PCR analysis revealed that the 39 bacterial isolates could be divided into 12 clusters at the 0.9 dissimilarity percentage level. The 39 bacterial isolates had their own specific band patterns, showing obvious genomic heterogenicity and rich genotypic polymorphism genetic diversity between each isolate.

采用rep-PCR技术对39个细菌分离株进行聚类分析，在rep-PCR图谱的相异百分数为0.9的水平上被聚类为12个类群，39个分离株各自具有独特的带型，说明各细菌分离株的基因组之间存在显著异质性，表现出丰富的基因型多态性。

In this dissertation, several recombinant unlabeled as well as 15N- or 15N/13C-labeled proteins were expressed and purified in large quantities. We then carried out circular dichroism and heteronuclear multidimensional NMR experiments to gain insight into the structure-function relationships on these proteins, as described below.

在本篇论文里，我们表现并纯化出大量所欲探讨的重组蛋白质，利用碳-13与氮-15同位素来标定这些重组蛋白，以旋光光谱及异核多维核磁共振技术来探讨这些蛋白质的结构与其功能的相关性，内容如下

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。
