能量传递

Bioenergy transfer appears in the motor-protein, actin, actomyosin, collagen-protein and so forth, so thatα-helical protein with three-chain becomes the object of study.

由于生物能量传递是在马达蛋白，肌动蛋白以及胶原蛋白等中进行的。

The coated strip goes up into cooling tower and is cooled by air blower and water to room temperature .

热从高温物体流向低温物体是一个能量传递过程，它使温度趋于均匀。

Methods of energy transfer are methods whereby the energy of a system may be increased or decreased.

能量传递的方法就是使一个系统的能量可以增加或减少的方法。

Further picosecond PL studies on dendronized PFs show that the fluorene-based emission in dilute solution follows a single exponential decay, whereas those in thin film decayed in a multi-phase manner and the lifetime prolongs with the generation of dendronization. These observations are discussed in terms of dispersive transport happening between adjacent chains in film. The dispersive relaxation can be controlled by site isolation of bulky dendrons. Our results prove that dendronization is highly effective in controlling the inter-chain interactions of fluorene-based polymers.

不同代数树枝化聚芴的时间分辨荧光动力学研究结果表明，溶液状态下的发光为单指数衰减行为，而薄膜状态下的发光为多指数衰减行为，且其发光寿命随树枝化代数增加而增长，表明树枝化基团抑制了邻近的聚芴分子之间能量传递所致的激发态能量耗散。

Highly branching degrees. All these results demonstrated that highly branched structure would effectively impede the intra- and interchain energy migration, especially in solutions; and remarkably influence the energy transfer process in the solid state.

所有这些结果表明了高度支化的结构能有效地阻止链内和链间的能量转移，其还显著地影响了固态中能量传递的过程，进而影响薄膜态的荧光效率。

The electronic interaction between the triarylamine units and porphines macrocycle in 4a-c and 10a-c were investigated by UV-vis absorption spectroscopy and fluorescence emission spectroscopy, and the results showed that there was a good energy transfer between triarylamine units and porphines.

经紫外吸收光谱和荧光发射光谱研究表明在化合物4a-c和10a-c分子中三芳胺基团与卟吩母体之间有很好的能量传递，使得三芳胺基团吸收的能量通过卟啉发色团发射出去。

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.
