凸面的

Distraction loads can not correct spinal rotatory deformity. Derotation can be achived by applying rotation forces. Improper distraction loads will lead to lumbar kyphosis.

单纯于脊柱凹侧施加撑开力作用可矫正该模型中脊柱冠状面的侧凸畸形，但是若是要将畸形彻底矫正，所需要施加的纵向撑开力有可能超出椎弓根或椎板的破坏载荷而导致椎弓的骨折。

This result shows that if the image of the Gauss map of an evolution convex surface with planar boundary covers some hemisphere, such a surface maybe be of infinitesimal nonrigidity for the isometric infinitesimal deformation of planar boundary.

这个结果表明如果带平面边界的凸旋转曲面的Gauss映照像覆盖了某个半球，这曲面对于保持平面边界的无穷小等距形变来说可能是非无穷小刚的。

Loss of lordosis in t he deformity should be corrected as much as possible to achieve adequate stabili zation in the sagittal planes,thus relie ving back pain.

畸形中最重要的是生理前凸的丢失，应该尽可能的纠正以达到脊柱矢状面的平衡，从而缓解腰背症状。

Two-dimensional texture mappings are summarized in this paper including Catmull algorithm and Blinn algorithm, two-step texture mapping, environment mapping and bump mapping. Moreover, a new method of regional texture mapping based on intermediate surface is presented and a new algorithm is promoted to reduce texture distortion in the process of mapping onto the sphere surface.

在二维纹理方面，本文讨论了适用于参数曲面的Catmull算法与Blinn算法，适用于一般曲面的两步纹理映射技术，现已广为应用的环境纹理映射技术及凸包纹理映射技术，还分析了纹理映射的几种快速反走样技术。

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。
