完全性条件

The concept of the reverse gcometry CT has been borrowed and extended. The fully reconstruction conditions and the relevant reconstruction algorithm in view of parallel and fan beam projection are given too.

3提出了倒置结构断层CT的概念，并就平行束和扇形束两种情形，给出了倒置结构断层CT的完全性条件、成象结构的各参数之间必须满足的条件及重建算法。

Under the identical experimental conditions, cut the trunk of the right facial nerve. Two weeks later. the caudal end of the divided facial nerve was anastomized with the cephalad end of the divided main trunk of the nerve to the masseter muscle.

在相同实验条件下，切断家兔右侧面神经主干，造成完全性面瘫。2周后，寻出麻痹侧面神经远心端与嚼肌神经主干近心端，在手术显微镜下做神经束膜、神经外膜吻合。

This algorithm is easy to be adjusted if some timetabling conditions are changed.

本文试图从国内务大学的实际教学管理特点出发，在时间表问题的基础上加上种种限制和扩充，提出一个符合国内实际情况的实用大学课程表问题模型PTPM，並从算法的完备性和完全性考虑出发，研究在各种教学管理设施条件下的实用而又有效的大学课程表调度算法，以此来说明寻找一般调度问题的实用算法的一些基本思想。

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。
