For ALIF, this ranged from 0.8 (complete, 100% fusion) to 3.3 (solid fusion of the posterior 25% disc space). For PLIF, the numbers were more aried, ranging from 0.7 (complete, 100% fusion) to 6.9 (solid fusion of posterior 25% disc space with bilateral facetectomy). For intertranserse process fusion, the least motion was with a solid bilateral fusion, with medial healing to the pars (2.0); the greatest motion was found with a solid unilateral fusion without medial healing (6.0). Interspinous process fusion allowed only 1.9 of motion.

前路椎间融合，范围是0.8度（完全、100%融合）到3.3度（后方椎间隙25%的稳定融合）；后路椎间融合范围较大，是0.7度（完全、100%融合）到6.9度（伴有双侧峡部近内侧融合的后方椎间隙25%的稳定融合）；横突间植骨融合，最小值2.0度是双侧偏内侧稳定融合，最大值6.0度是单侧且不偏向内侧融合；椎板棘突间植骨融合只出现1.9度的活动度。

METHODS: 27 maxillary second bicuspid teeth with two canals and one isthmus were divided randomly into 3 groups with 9 in each.

27颗根管结构为一个峡部连接2个主根管的离体上颌第二前磨牙，随机均分为3组，分别采用3种处理方式进行倒预备。

Third, it evaluated the diagnostic significance of associated cardiac lesions, coarctation shelf, and isthmal flow disturbance.

再次，评估相关心脏缺损、缩窄架及峡部血流涡流的诊断意义。

Results The characteristic performance that the spondylolysis of lumbar spine was the bone wreath consecution to break off.

在CT诊断明确的目的探讨CT在腰椎椎弓峡部不连诊断中的临床价值及提高检出率。

The incidence of double root canal is high in the single-rooted maxillary premolars.

上颌前磨牙单根双根管率较高，其根管峡部的发生率因此也较高。

Foetus in wrong position; abnormal fetal position; malpositionThe main injured parts included prolapse of lumbar intervertebral, muscles of waist and back myofascitis, epiphysitis of lumbar spine, malposition of lumbar spine and lumbar muscle strain.

结果表明：97.5%的运动员患有腰部损伤，100%的运动员表示有过不同程度的腰部疼痛；发病率前5位的损伤部位是腰椎间盘突出、腰椎峡部裂、棘突偏歪、腰椎错位和腰肌劳损；损伤多发生在重要赛事前准备期。

Athletes who engage in sports with repetitive hyperextension have been shown to have an increased risk of spondylolisthesis.

从事需要反复过伸腰部运动的运动员，其发生脊椎前移的风险较高。4，5我们的病人尽管从未行走过，但产生了一个峡部的骨折。

The size of the reamer was regarded as the diameter of the isthmus.

软钻的直径即为股骨峡部的直径。

The cerebellar hemispheres oppose one another in the midline due to absence of vermis.

由于缺乏小脑蚓部，双侧小脑半球在中线上不连续，峡部和中脑前后径较小，这可能是由于小脑上脚缺乏十字交叉的纤维束。

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。
