结果 18项软组织指标中5项角度指标的改变在男性组与女性组的改变均有统计学意义， 13项线距测量指标中的上唇厚度、下唇厚度、鼻凸度均增大，而鼻底厚度在男性组与女性组改变不同。

At eccentricities of 20 degree, VEP yielded the largest responses to gratings perpendicular to the visual field meridians through stimulus locus and the lowest responses to meridionally oriented gratings.

在距中央凹20°视角同心圆的八个刺激位置上，VEP反应幅度对与向心线垂直方位的光栅刺激，有统计意义上的优势。

This paper described the preparation of nanometer TiO_2 by means of direct precipitation and homogeneous precipitation with titanyl sulfate,which is a semifinished product during the production of TiO_2 using sulfuric method as raw material.

我国二氧化钛(TiO2，俗称钛白)工业自1956年生产搪瓷和电焊条开始，距今已有近50年的发展历史。近10来，我国TiO2工业发展很快，取得了令人瞩目的成就，其中硫酸法TiO2的生产与国外先进技术相差无异，总生产能力已跃居世界第二位，仅次于美国[1]。

Factors affecting wind deflection caused discharge include wind speed, wind pressure ununiformity coefficient ,induded angle between wind and conductor,and transmission line parameters,etc.

风偏放电的影响因素有风速、风压不均匀系数、风与导线夹角、输电线路的参数等，通过对这些因素的逐一分析，明确了风速、风压不均匀系数和垂直档距对绝缘子风偏角影响较大。

Taking Guixin highway as a case, the pollution state and its change regularity in vertical direction are analyzed, which proves that the heavy mental pollutant enriches within 5m under the ground and decreases towards ground surface but increases near the surface slightly that may have something to do with the convoluting and accumulating effects of tail gas.

文章以贵新路为例，分析了公路边坡土壤重金属污染物的垂向污染状况和变化规律，得出了路坡重金属污染的富集带约分布在距地面5m处，随着高度的增加污染物含量减少，但到了路坡坡顶又出现小幅增高现象，这有可能与汽车尾气卷扬和淀积效应有关。

When the poisonous pesticide is degraded, it is likely pollute soil and water. If the underground water level is within 6 meters to the ground, the eluviated pesticide may pollute the underground water. Thus we have to be cautious when using pesticide

一切的化合物都具有毒素，当施药隐埋后应考虑到农药对土壤、水体降解过程中，药剂施用毒土形成后的向下淋溶径流降解，当地下水位距地面6米范围内时，向下淋溶径流降解的农药就有可能对地下水造成污染，故所应持极其注重态度对待。

It is found that the melting points of borides of IVB and VB group elements are higher than their simples. It is because their hybridization levels are higher, and their single bond radius are shorter.

发现IVB，VB族元素的硼化物熔点都比相应的单质有较大提高，原因是组成元素的杂阶升高，单键半距随杂阶升高而逐渐下降。
