Having a chromosome number greater than but not an exact multiple of the normal euploid number.

超倍的有一个染色体数目的，此数目比正常超倍体数目大，但不是它的整倍数

Objective: Renal fibrosis was the common way of various of chronic nephropathy developping into Chronical renal failure Just in our country, the occurring ratio of CRF was 1-1.5 ten thousand every year, and showed raising tendency each year.

目的：肾脏纤维化是各种肾脏疾病进展到终末期肾衰竭的一个共同通路。我国慢性肾衰竭的发生率为1-1.5万／年，且有逐年上升趋势。目前尚无有效的治疗方法阻止CRF发生。

Objective The influence of smoking to smokers has been known to all, however, hazard of cigaret smog to passive smokers isn't taken into account carefully by people. It has been reported that 51.9 percent of non-smokers are suffering from passive smoking and women are import component.

目的吸烟对吸烟者本身的危害已经众所周知，但香烟烟雾对于被动吸烟者的危害还未引起人们的足够重视；据报道，有51.9%的非吸烟者遭受到被动吸烟的危害。

Objective To explore the effects on images from the space location of spectrum and scanning parameters,and summarize the technological essential and application hints.Methods 65 patients were scanned in brain with magnetic resonance spectroscopy,the location and the size of region of interesting and other scanning parameters values （FOV,frequency matrix,phase matrix,saturate cingulum,etc.） were changed intentionally,the values of full width at half maxium and water suppression lever were recorded.A preliminary evaluation of the resulted waves and the relationship between the parameters data and the quality of the MRS waves were probed.

目的 观察波谱空间定位和扫描参对图像质量的影响，并初步小结应用要点方法对65例头颅检查的受检者行磁共振波谱扫描，有目的地改变感兴趣区域的位置、小和其他参数设置（FOV、频率矩阵、相位矩阵、预饱和带等），记录预扫描后系统显示的半高宽、水抑制程度等数值，并对扫描后显示的图像质量进行初步评价，探讨些数值与波谱质量之间的关系。

There are shovel blades equipped bottom of the cinquefoil shelf. When shovel blades rotate with rollers, they throw up the materials and send them into the space between rollers and ring and then form a material bed. The material bed produces centripetal force as a result of rotating of roller. The material is crushed by the centripetal force.

磨辊吊架下装有铲刀系统，其位置处于磨辊下端，铲刀与磨辊同转过程中把物料抛起喂入磨辊与磨环之间，形成垫料层，该料层受磨辊旋转产生向外的离心力碾压，达到制粉目的。

At first,you must have clear purpose of learning.

首先，要有明确的学习目的。

The major purpose of this article was to illustrate the innovating instruction of the topic-"triangle" for the third graders. From the experience of the classrooms, it is considered that the curriculum is only to instill into children some geometric nouns, such as the sides, the apexes and the angles. A closed graph with three angles is usually to be named as a triangle without thinking about children's understanding of the real meaning.

本文的主要目的乃是针对教学者本身以往在教国小三年级学童的「三角形」这个单元时，自觉只是在灌输孩子一些几何的名词，例如：这个就是边、顶点和角；有三个角的封闭图形就是三角形，并没有去考虑到孩子是否真正的理解这些语词的涵意。

After analysis of multiple sequences alignment, phylogenetic tree and similarity of sequences, it was shown that Ac-ASP has similar relation with Am-ASP, and shared high homology with other Hymenopteran and Coleopteran. From above analysis, we firmly suggest Ac-ASP1 and Ac-ASP2 belong to OBPs family and Ac-ASP3 belong to CSPs family.

通过多序列联配、系统发育树及序列相似性分析，Ac-ASP除与西方蜜蜂Am-ASP亲缘关系较近(相似性达到80％以上)外，与其它膜翅目以及鞘翅目的OBPs及CSPs也有一定的亲缘关系(相似性达到30～60％)，且Ac-ASP1和Ac-ASP2应为OBPs，Ac-ASP3则应为CSPs； 4。

Objective To determine whether antibiotic resistance probability of Coliform bacteria in sanitary sewage is in existence.

目的 检测生活污水中大肠菌群对当前常用抗生素是否有耐药性。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
