It is Concluded that the mode of action of pyrimidine benzylamine differs from the other typically commercial ALS inhibitors, such as sulfonylurea and pyrimidine salicylic acid herbicides. Its herbicidal activity is activated by the metabolic processes in the plants.

离体条件下，化合物104-4 IC_(50)＞100 mg／L，而除草剂双草醚IC_(50)值为10~(-5)～10~(-4)mg／L，说明化合物104-4对离体ALS没有抑制作用；活体条件下，化合物104-4对ALS有一定的抑制作用，且随着处理时间的延长，酶活力降低，对ALS的抑制作用增加。

Benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene]dichloro(2-methylpyridine)ruthenium (62), benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene] dichloro(2,4-dimethylpyridine)ruthen ium (63) introduce ortho substituted pyridine as dissociating ligand to weaken Ru-N bondand accelerate dissociation of pyridine derivative ligand through steric hindrance.

在钌卡宾配合物[1，3-二-(2，6-二甲苯基)-4，5-二氢咪唑基]-苯亚甲基-(2-甲基吡啶)-二氯合钌(62)，1，3-二-(2，6-二甲苯基)-4，5-二氢咪唑基1-苯亚甲基-(2，4-二甲基吡啶)-二氯合钌(63)中，邻位取代的吡啶作为解离配体，通过邻位基团的空间效应削弱钌-氮配位键，使配体更易解离，提高了催化剂的初活性。

Male flowers pedicellate or sessile; sepals 4-6, distinct, usually unequal, imbricate; petals absent; stamens 1-25, 1 to several whorls surrounding disk or outer ones inserted at margin or sinus of disk, inner ones inserted on disk; filaments free; anthers bilocular, usually introrse, rarely extrorse, longitudinally dehiscent; disk flattened or concave, margin shallowly or deeply fid; rudimentary ovary very small or absent.

雄花有花梗或无梗；萼片4-6，离生，通常不等长，覆瓦状；花瓣无；雄蕊1-25，1或数轮围绕花盘或外轮着生于花盘边缘或凹缺，内轮着生于花盘；花丝离生花药具2室，通常内向，很少外向，纵向开裂；花盘扁平或凹，边缘浅或深裂；不发育子房非常小的或无。

Ma,and lithosphere delamination and thermal exhumation during 196～163?Ma.The rapid thermal exhumation,co\|occurred with extensive regional metamorphism and intermediate\|acidic magmatism,implied that the subducted slabs had broken off and delaminated.The p T t path of UHPM consists of two curves,i.e.,a barrette\|like curve reflecting the process of cold slab subduction and exhumation,and a crescent curve representing the thermal exhumation after slab breakoff.

通过全面评述该区变质岩研究成果，作者认为：超高压变质岩的形成和剥露经历了240～200 Ma的板片冷俯冲冷折返和196～163 Ma的岩石圈拆沉热折返；热折返伴随了广泛而强烈的区域变质作用和中酸性岩浆活动，指示板片断离拆沉的发生；超高压变质岩p-T-t轨迹由两部分组成，即反映板片冷俯冲冷折返过程的发夹状曲线和指示板片断离拆沉热折返过程的新月形曲线。

Comparing with the photodissociation of bromobenzene, the extra fluorine atom of fluorobenzene accelerates the rate of the internal conversion from the state to the state, and the different positions on the phenyl ring also have distinct effect on it.

与溴苯相比，氟溴苯上的氟原子显著加快了解离的速度，并且氟原子在苯环上的位置的不同对解离速度也有显著影响。

The curve crossing probability rises gradually with the wavelength, suggesting that the conical intersection be located close to the exit channel. Br is the primary product of the photodissociation of fluorobromobenzene and bromobenzene near 266nm and it is generated through two channels.

由于势能面交叉几率随激光波长的增加有增大的趋势，我们推测势能面的交叉区域应靠近解离通道的出口。o，m，p-C6H4FBr和C6H5Br在266nm激光作用下的光解存在两种解离通道。

In the first case, the products of the MFW4/31 amplification were loaded when bromophenol blue dye from MFW7/9 sample migrated to a 3-cm distance from the wells, while in the second case, MFW17/26 products were loaded when the dye from MFW13/20 reached 4.5 cm.

在第一种情况下，当溴酚蓝染料从MFW7/9 样品迁移到离加样穴 3-cm 距离时加入MFW4/31 扩增产物，而在第二种情况下，当溴酚蓝染料从MFW13/20 样品迁移到离加样穴4.5 cm距离时加入MFW17/26 产物。

ConclusionThe extracts of Phrynium capitatum Willd flower with butyl alcohol and with water have excitatory effects on the non-pregnant or diethylstilbestrol-injected animal uterus in vitro ,which is more potent than that of Herba Leonuri fluid extract.

结论棕叶花正丁醇、水溶性组分对家兔、豚鼠、大鼠、小鼠离体子宫有明显兴奋作用。对离体子宫兴奋作用比益母草流浸膏显著。

MethodsIsolated uterus preparations of above animals were made according to the literature and its contractive effects to four different extracts of Phrynium capitatum Willd flower were observed and recorded with BL-410 experimental system for biological function; the EC50s of the extracts were determined and compared with it of Herba Leonuri fluid extract.

ConclusionThe extracts of Phrynium capitatum Willd flower with butyl alcohol and with water have excitatory effects on the non-pregnant or diethylstilbestrol-injected animal uterus in vitro ,which is more potent than that of Herba Leonuri fluid extract.

结论棕叶花正丁醇、水溶性组分对家兔、豚鼠、大鼠、小鼠离体子宫有明显兴奋作用。对离体子宫兴奋作用比益母*流浸膏显著。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
