可保持的

This Palladacycle catalyzed Heck reaction was characterized by a wide variety of substrates, mildness of reaction conditions, freedom from protection of inert gases and high catalytic activity retainable after repeated uses.

二茂铁亚胺环钯化合物催化的Heck反应具有底物范围较广，反应条件温和，不需要惰性气体保护，催化活性高且催化剂可重复使用仍能保持活性的优点。

Results:(1) The 90Y activity was higher while the contumination of 90Sr was less than 0.0031%;(2) The efficiency of 90Y-labeled antibodies was over 90%,the activity of labeled antibody maintained 82.3%;(3) Tumor size of all 90Y-antibody-treated model was significantly less than that of all 90Y-Cl3-treated model, the average survival time of the mice of the 90Y-antibody-treated group was significantly longer than that of the 90Y-Cl3-treated group;(4) In the tissue sections extensive necrosis was observed in all 90Y-antibody-treated tumor, the living tumor cells were immunohistochemically stainable with PcNA.

结果：(1)EDTA淋洗法制备90Y纯度高，其相对含量可达99.997％；(2)单克隆抗体的90Y标记率达90％以上，抗体蛋白活性保持82.3％；(3)治疗结果表明治疗组肿瘤明显小于对照组，原肿瘤的指数生长规律遭到破坏，治疗组生存期明显长于对照组；(4)组织学切片显示治疗组肿瘤有广泛坏死，PcNA免疫组化显示治疗组肿瘤细胞增殖受到明显抑制。

This outlet member is turnable around a turning axis (26) in parallel with said rotational axis (12) and is held by a spring (31) pressed radially outwardly in the chamber (16) against and partly into a liquid body rotating with the centrifugal rotor.

此出口构件可绕一根与所述旋转轴线（12）平行的转动轴线（26）转动，并被一个弹簧（31）径向向外挤压保持在室（16）内，对着并局部进入随离心转子旋转的液体实体。

The script assigned to after runs once the transition completes-although if at any time an uncaught exception is raised on a script, this will cause the transition to fail, the object to remain in its original state, and the exception to display to the user.

虽然在任何时候，未被捕获的异常可在脚本运行时被抛出，但是这都会引发过渡失败。对象仍会保持它原来的状态，异常则会显示给用户。
