During the study of multiphoton ionization of pyridazine-〓 clusters, a sequence of 〓 was observed.

在对哒嗪-水团簇的多光子电离研究中，看到一系列的质子化产物离子〓。

The multiphoton ionization mechanisms of hydrogen-bonded cluster systems: pyrimidine-〓 and pyridazine-〓 were studied using TOF mass spectrometer at 355 and 532nm laser.

本文利用355，532nm波长的激光和TOF质谱首次研究了嘧啶-甲醇（〓，pyrimidine-〓）以及哒嗪-甲醇（〓pyridazine-〓）氢键团簇体系的多光子电离机理。

In comparison with 〓ligand the substitution of one phenyl groupby pyridyl ligand renders this cluster a self defocusing effect different with previousbutterfly shaped clusters, so the peripheral ligands may also play an important role onthe NLO effects.

配体中的吡啶取代基取代苯基的微小改变使标题化合物具有了不同于以往蝴蝶状簇合物的非线性折射性质，即表现为自散焦，从而说明外围配体对非线性也具有大的影响作用。

The changes on models allow them to qualitatively demonstrate an innovation\'s dynamic modes, and quantitively predict the innovation\'s future from the point of the different views.

其中曲线簇模型可以更清晰更准确地反映渗透的动态过程，几个修改模型也从不同的角度出发，对扩散的动态过程的方向变化及结果进行更为准确地量化预测。

Spikelets in loose, spicate clusters; palea not keeled; lodicules absent (to 3); glumes usually absent; rachilla internodes usually disarticulating.

长枝红褐色，呈&之&字形弯曲，光滑，有托叶刺或不明显；短枝在二年生以上的长枝上互生；脱落性小枝较纤细，无芽，簇生于短枝上，秋后与叶俱落。

Panicle lanceolate to oblong in outline, loose to rather dense, 10–25 cm, greenish or purplish, shining; branches clustered,scabrid.

圆锥花序披针形到长圆形轮廓，释放与相当紧密，厘米，带绿色或带紫色，发亮；分枝簇生，粗糙。

Inflorescences of solitary or clustered flowers subtended by scarious bracts and bracteoles.

单生或簇生花的花序以干膜质的苞片和小苞片被包着。

Flowers unisexual, on same plant or not, sessile, clustered at axils and at apex, in solitary or complex thyrsoid structures; each flower with 1 bract and 2 bracteoles, scarious.

与否单性的花，在相同植株上，无梗，簇生在腋和在先端，在单生或复合聚伞圆锥花序结构；每花具1苞片和2小苞片，干膜质。

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。
