The numerical results of river channel planform change, longitudinal bed profile, channel cross section, water surface profile and channel sediment transport are analyzed and discussed.

根据模拟得到的河道平面形态、横断面形态、河床纵剖面，沿程水面线及沿程输沙率的变化，分析了河床初始比降、入口含沙量、流量和河岸抗冲性等各种因素对河型转化的影响。

Methods: The head and neck of 20 adult cadavers were selected and cut into cross section successively. Infratemporal space and its adjacent structures were observed and measured its length, width and area with vernier caliper and planimeter.

成人尸头颈部20例作连续横断面，观察颞下间隙及邻近结构的解剖学关系，利用游标卡尺及求积仪分别测量其长径、横径和面积。

This may not be distinguishable in any given patient but is observed in cross-sectional studies comparing elderly to younger individuals and is believed to be due, at least in part, to a reduction in pre-existent CNS activity.

这也许不能在任何老年患者中鉴别出来，但可从比较老年人和年轻人的横断面研究中观察出来，这种现象被认为是由于老年人的中枢神经活性降低。

These data resole the controersy that the multifidus cross-sectional area reduces rapidly after lumbar injury.

上述数据解决了腰椎损伤后多裂肌横断面积是否迅速减少的疑问。

Methods Cross-sectional study was performed for all AIDS patients registered in the local center for disease control and prevention with free thoracic roentgenogram,sputum-smear examination, purified protein derivative skin test and CD4 count.

方法对当地登记在册的AIDS患者进行横断面调查，免费进行X线摄片、痰涂片、PPD皮试和CD4计数。

We simulate the pore water flow and the associated solute transport in a salt marsh based on an imaginary creek section.

基于假定的潮沟横断面物理条件，对孔隙水流动及溶质运移过程进行了模拟分析。

The temperature field of cross section and temperature variation graph in bar and rod continuous rolling process were done by FEM.

本文采用有限元方法对棒线材连轧过程轧件温度场进行了解析，解出了轧件横断面温度场并绘制了连轧过程中轧件温度变化曲线，可以看出变形区热传导作用对轧件表面温度有较大的影响，计算结果表明，在精轧机组之前设定值与轧件表面温度的计算值吻合，在进入精轧机组之后设定值更接近于轧件平均温度的计算值。

The cross sectional area at the level of pisiform bone was measured in transverse plane.

横断面测量豌豆骨水平的神经面积。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
