可交替性

To variational inequalities with separate structures, the thesis presents a descend method based on the alternating directions method, and some numerical results demonstrate that the new method is effective in practice.

对于结构可分的变分不等式，本文在交替方向法的基础上提出了一种下降方法，并给出了相应的算法收敛性证明与数值试验结果。

Fusion dissociation can be achieved in different ways , dissimilar ocular targets(e. g., Maddox rod), vertical prisms , separate targets for each eye(e. g., in a stereoscope), or alternate occlusion(e. g., cover test).

5融合分离可采用不同的方法实现，如采用双眼视标差异法、垂直棱镜法、双眼视标分离法、交替性屏蔽法等。

With the intrinsic recovery mechanism, the continuity index of DONet remains acceptable even under highly dynamic networks (alternating in less than 1 minute).

由于内置的恢复机制，即使在高动态的网络里（交替不到1分钟），DONet的流畅性指标保持在一个可接受范围内。

He usable with can reach more than 5m; but the level adjusted is less than 800mm; especially suitable for the drainage in the ditch where the sewage water is alternatively oxygenized, or for the distribution in large type of distributing well.

YX 型密封性效果好，几乎达到0泄漏状态，适用宽度可达5m 以上，但调节水位一般在800mm 以下，特别适用于交替运行的氧化沟排水，或大型配水井配水，配套专用启闭装置，仅需注明手动或电动即可，无需另外选用启闭机。

Results The average onset age of moyamoya disease was very young. Female was dominant in our studied. Younger patients with moyamoya disease mainly suffered cerebral ischemia (87.5%). Adult patients suffered more cerebral hemorrhage (41.2%). Among clinical manifestations, headache, vertigo, paralysis, hemiplegia or alternative hemiplegia were common symptoms. Sometimes aphasia, dementia, visual acuity were decreasing, epilepsy and chorea minor might occur. 14 cases had received CT examination, but none was diagnosed moyamoya disease by CT. All patients received MRI and MRA examinations were diagnosed as moyatnoya disease.

结果 烟雾病发病平均年龄较轻，女性多于男性；少儿烟雾病患者以缺血改变为主(87.5%)，成年烟雾病患者缺血改变(58.8%)与出血改变(41.2%)相当；临床以头痛、头晕、肢体无力或偏瘫或交替性瘫痪为主要表现，同时可伴失语、智能下降、视力下降、癫痫发作、小舞蹈发作等表现。14例行头CT检查仅示颅内病灶，均未提示烟雾病；25例均行MRI和MRA检查发现颅内病灶，显示颈内动脉虹吸末段和大脑前或中动脉近段狭窄或闭塞，并有脑基底部异常血管网及侧支循环形成，均被诊断为烟雾病。

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。
