It is well known that the mechanical injury seldom causes total transection of the cord in patients with acute co...

众所周知，机械创伤很少产生脊髓的完全横断，但在临床却可表现为脊髓完全损伤。

From April 2000 to December 2004, we had crated 93 limbs fractures, among then there were 59 femur fractures, 30 tibia fractures, 4 hummer fractures.

在2000年4月-2004年12月收治的93例四肢骨折中，股骨骨折59例，胫骨骨折30例，肱骨骨折4例；骨折类型分类：粉碎性骨折42例，长斜形及多段骨折30例，横断骨折21例。

Objective To explore the changes in expression of substance P in the dorsal root ganglion after hemisected spinal cord injury.

目的探讨脊髓半横断损伤对脊神经节P物质表达的影响。

METHODS: Eight fresh patellae specimens were divided into two groups at random, AO steel wire group (n = 2) and absorbable tension band group (n = 6) to create models of transverse fractures, which were separately fixed by absorbable tension band, steel wire tension band + Kirschner wire to measure their biomechanics function. If fracture gap reached 1.0 mm, the fixation failed.

随机分成AO钢丝组2个和可吸收张力带组6个，制成横断骨折模型，分别用可吸收张力带、钢丝张力带加克氏针进行内固定，测定它们的生物力学性能，骨折端分离1.0 mm为固定失效。

Methods Twelve half pelvises were classified into 3 groups randomly.

笔者选用髋臼横断骨折常用的3种内固定方法进行生物力学稳定性比较。

As an overall and crossing subject, system science saturates all fields.

作为一门综合性、横断性学科，系统科学具有向一切领域渗透的总趋势。

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。
