研究结果表明：合成的化合物在非极性溶剂中有双重荧光的稳态发射行为；双重荧光中的长波长发射经时间分辨光谱研究为双指数发射衰减；其中的长寿命衰减是由于该类化合物在非极性溶剂中激发后经过分子内电荷转移形成了激基复合物所致，而产生该激基复合物的直接原因是由于在非极性溶剂中的&harpooning effect&所致，短寿命则来自于该类化合物激发后在溶液中发生了分子内电荷转移的直接衰减。

Our results suggested that in lampreys and most of other vertebrates, there might be only one kininogen gene, which was fused by certain sequences during vertebrate evolution and encoded proteins with more functions; however, another special kininogen gene, only encoding the bradykinin domain with multiple copies in some species, arose only in amphibians for adapting themselves to the unique environment.

"Although everyday levels of stress are necessary to stimulate normal brain development, excess levels can be harmful," said Carrion, likening the biological effects of increasing amounts of stress to an inverted U.

&尽管每天一定水平的应激是刺激正常大脑发育所必需的，但是过度的应激水平却是有害的。&

METHODS Mice hot-plate, writhing test and mice menalgia model of acute stress blood stasis rat was used to compare therapeutic action of the three preparations RESULTS Both chuanxiong formula granule and decoction pieces standard broth of liquored Chuanxiong formula granule and decoction pieces stand ard broth could prolong pain threshold, extend incubation period caused by acetic acid andoxytocin, reduce writhing frequency, and improve some indexes of hemoreology in acute stress blood stasis rat.

选择热板法、扭体法、痛经模型、急性应激血淤血液流变性等方法，比较川芎配方颗粒及饮片、酒川芎配方颗粒及饮片的主要药理作用。结果川芎配方颗粒与川芎饮片标准汤剂、酒川芎配方颗粒与酒川芎饮片标准汤剂均能延长小鼠热板痛闭值，均能延长醋酸所致扭体反应的小鼠扭体潜伏期并减少扭体次数，均能延长小鼠痛经模型中催产素所致扭体反应的潜伏期并减少扭体次数，均具有改善急性应激血淤大鼠血液流变的作用。

The expression of HSP70 and HSP70mRNA and the activity of SOD and NOS in uterus were elevated with preventive acupuncture and preventive moxibustion and the influence on the activity of SOD and NOS was mainly refected in 12th and 16th month. It indicated that preventive acupuncture and preventive moxibustion on Guanyuan point could relieve the abnormal activity of center of stress, promote the expression of HSP70 and HSP70mRNA and the activity of SOD and NOS in uterus so as to maintain the normal structure and function and prolong the retrograde degeneration of uterus. It might be one of mechanisms of protecting uterus with preventive acupuncture and preventive moxibustion.

提示逆针灸关元穴对随后更年期大鼠子宫产生保护作用机制可能通过减缓应激中枢的异常活跃状态，提高不同月龄外周子宫组织细胞HSP70及mRNA的表达，以促进组织SOD、NOS活性的增强，对抗应激激素及卵巢功能衰退引起的子宫靶器官的结构及功能的改变，提高机体抗氧化能力，增强NO/NOS的局部调节作用，减轻随后更年期衰老过程中自由基对组织器官的损害及组织器官功能紊乱，对于维持子宫正常的结构和功能，延缓子宫退行性变具有重要作用。

This project installs cyclone separator behind the carbueter of vaporization section in residue-type chemical fertilizer ammonia plant and revamps the carbueter structure so that the ash flows with cooling water to the separator instead of remaining in the carbueter.

渣油型化肥厂合成氨气化工段的气化炉后加置旋液分离器，改造气化炉结构，使灰渣不滞留于气化炉中，随激冷水流到旋液分离器中，将激冷水中全部能堵塞后序流程设备的灰渣沉淀，定期排放到屯渣槽中，干净的不含有堵塞设备的灰渣的碳黑水送往碳黑回收工段。

Mathematical model of nonlinear vortex-induced vibration was presented for predicting the nonlinear dynamic responses of submerged floating tunnel tethers which were subjected to wave, current and oscillatory displacements at their upper end in horizontal and vertical directions.

建立了水中悬浮隧道锚索在波流场中涡激振动的非线性数学模型，考虑了锚索的几何非线性对其涡激振动的影响，并应用有限差分法求解了锚索的运动控制方程。

The results show that, influenced by the rarefaction waves from the left sharp corner, the reaction zone is separated from the leading shock. Then, the detonation is degenerated into the deflagration. The winkled reaction front can be clearly identified in numerical schlieren and temperature contours.

结果表明：气相爆轰波在分叉管中传播，分叉口左尖点的稀疏波导致诱导激波后压力、温度急剧下降，诱导激波和化学反应区分离，爆轰波衰减为爆燃波。

They have intense absorption bands in the red region so that they can collect more energy available in the solar spectrum.
