比例性

The high BVP percentage reported in the AF group is even more astonishing considering the low use of chronotropic-negative drugs and the lack of use of a ventricular rate regularisation feature, extremely important to ensure biventricular capture in cases of fast irregular rhythm.

在Khadjooi的研究中，在包括阵发性房颤患者的AF的群体中引入了2个重要的偏倚：阵发性房颤患者两心室同步率要高于永久性房颤患者。（AF患者的BVP比例为87%）；阵发性房颤患者的&临床&行为如SR患者。在AF患者群中，接受CRT的正性效果与SR人群相比要差。

The results indicate that the mass size distribution of fly-ash particles in the inlet of the WFGD system is typically disturbed bimodally, the peaks are approximate at 1 and 3 μm. And the shape of particles is regular sphericity, the mass ratio of PM2.5 to PM10 is about 0.434. The total mass concentration is about 85 mg/m3. In the outlet of the WFGD system, the mass size distribution of fly-ash particles is also bimodal. The proportion of fine particles increased, the mass ratio of PM2.5 to PM10 is about 0.764. Some fine particles are conglutinated and formed irregular agglomerate. The total mass concentration is under 23 mg/m3, the removal efficiency of total particles is 74.5%. The size removal efficiency is decreased observably with the range of particle size decreasing.

结果表明，WFGD系统入口飞灰质量粒径呈典型的双峰分布，峰值分别在1和3 mm处，颗粒多呈规则球形，PM2.5与PM10质量比为0.434，飞灰总浓度约为85 mg/m3标准状态；出口处飞灰质量粒径分布也呈现双峰性，其中细颗粒比例增大，PM2.5与PM10质量比为0.764，细颗粒间相互聚集粘连形成不规则的块状结构，飞灰总浓度在23 mg/m3以下，总飞灰的脱除效率为74.5%，分级脱除效率随粒径减小而明显下降。

With the increase of the deforested years, soil erodibility parameter increases.

2随着植被破坏开垦年限的增加，土壤容重逐渐增大，而毛管孔隙度逐渐减少；土壤水稳性团聚体呈减少趋势，且小团聚体所占比例逐渐增加；物理性粘粒随开垦年限的增加而减少，而粗粉砂呈增加趋势，表明土壤粗化现象明显。

Results Medical students' knowledge level of AIDS prevention was higher than those of normal student. No significant difference in understanding three transmission mutes of AIDS was found between medical students and normal students. There were significant difference between the two groups of students in some other transmission proutes, attitude to AIDS and sexual conception.

结果 医学生对艾滋病相关知识的了解程度高于师范生；医学生和师范生知晓艾滋病的三大传播途径的比例差别无统计学意义，但对某些传播、非传播途径的认识差异有统计学意义；两者在对待艾滋病的态度、性观念的方面差异也有统计学意义。

The paper also points out that, modern logistics can restructure and upgrade the regional industries by means of the effect of industrial relevancy when it serves for the social production and residents living, engenders new industries and enhances the internal proportions of the third industry. By integrating related functional operations, modern logistics is able to change the links between the knots and lines from random and loose connection to a kind of spatial structure of smoothness and steadiness, with which block and friction would be lessened and the function of regional economic constituents amplified while the regional income and the strength would be improved as a whole. Through intensifying the advantage of allocation of the centers of region, modern logistics induces regional elements of development to move towards advantageous locations while bringing key urban cities effects of scale economy and agglomeration economy, it then can be regarded as an operational platform for potentiating the growing polar of urban cities and boosting up the developing level of hinterlands, and an effective measure to balance urban and rural development and development among regions.

论文认为，现代物流在为社会生产和生活服务、形成新的产业形态、改善第三产业内部比例关系的同时，通过产业关联带动效应促进区域整体产业结构的优化升级；现代物流通过整合相关功能性活动，将经济网络中节点与线路之间随机连接、松散联系转变为顺畅交流、稳定合作的空间构造，从而减少区域经济运行中的阻滞性因素，放大区域经济发展要素的功能，提高区域经济系统整体效益和经济实力；现代物流通过强化经济中心的区位优势，促进区域经济发展要素向优区位运动，给经济中心城市带来规模效应、聚集效应和扩散效应，是强化中心城市增长极地位和提升经济腹地发展水平的操作平台，因而也是统筹城乡发展和区域发展的重要手段。

Various psychometric characteristics, time constraints, as well as qualities of estimation among prorating and linear equating procedures, were compared among 54 tetrads. Our results supported the use of the linear equating procedure.

以各种心理计量特质、时间限制、以及比例与线性方程式的质性估计程序来比较54组测验组型，结果支持使用线性方程式的程序。

The result indicated: The peppermint extraction joins by 0.3-0.35% proportion to the shampoo formula, with each kind of surface active agent compatibility for best, enables the formula to have the highest stability, and may achieve well increases soaks, the sterilization sterilizes and eliminates the dandruff the effect.

结果表明：薄荷提取物以0.3-0.35%的比例加入到香波配方中，和各类表面活性剂的配伍性为最佳，使配方具有最高的稳定性，并可达到最好的增泡，杀菌消炎和消除头屑的效果。

Increased wage income reduces the probability of rural households' demand for formal credit, and non-farm income does not impact formal credit demand but formal credit access. Besides household character, credit products and loan procedure also affect credit demand.

工资性收入负向显著影响农户的正规信贷需求，而非农经营收入占总收入的比例正向显著影响农户正规信贷的可得性，但对农户的正规信贷需求影响不显著。

The deep cultivation-root cutting in before winter stage would increasethe weight and ratio of root system in middle and lower layer,the resultswould decrease the root redundancy.

冬前深耘断根可增加中、下层根系的重量和比率，降低根系生长冗余性，控制最高总茎数，提高成穗数及成穗率，使籽粒产量中来自花后光合器官输送的比例增加，从而使产量提高，因而在旱地高产麦田应推广冬前深耘断根。6研究了降水量对旱地高产小麦耗水规律及产量的影响，拔节前降水多且占比重高，土壤供水量及占比重少，拔节后降水量减少且占比重低，土壤供水量及占比重高，利于在旱地高产麦田形成高产。

The earliest change of ERG in birdshot chorioretinopathy was the prolongation of cone ERG implicit time. Followed by the decrease of dark-adapted b wave amplitude. The b wave amplitude of cone ERG decreased later. The duration of the disease correlates with the amplitude of b wave in the same patient. The a wave was the last affected and the decrease of the a wave amplitude was disproportionate compared to that of b wave, revealing a typical negative type ERG.

结果发现最早的变化为锥细胞ERG潜伏期的延长；接着是暗适应b波振幅下降，锥细胞b波下降较晚，同一患者病程的长短和ERG b波振幅下降幅度一致；a波振幅下降晚于b波，且下降不成比例，出现负相ERG，可作为诊断此疾病的特征性ERG。
