In an undivided cell, the degradation of methyl red via indirect single and paired electrolysis in the presence of bromide and hydrogen peroxide redox mediators was explored.

本研究是於一未隔离式电解槽中，藉由Br-/Br2与O2/H2O2氧化还原媒子之间接催化分解甲基红之单一与组对电化学反应。

Forty-eight hours after transfection, cells were harvested to determine luciferase activity by illuminometer, In the presence of RU486 a 40-fold maximum activation of the luciferase reporter gene was observed in cultured cells, whereas in the absence of RU486, no significant activation was observed.

加入诱导剂RU486后，可以诱导表达荧光素酶，并在一定范围内两者呈正比，最高可以实现荧光素酶的40余倍的表达，而没有RU486时，几乎没有报告基因的表达，表明RU486诱导调控载体构建成功，可实现对目的基因的表达时间和表达水平的精确调控，为进一步的基因调控研究和基因治疗提供了良好的工具。

Forty-eight hours after transfection, cells were harvested to determine luciferase activity by illuminometer. In the presence of RU486 a 40-fold maximum activation of the luciferase reporter gene was observed in cultured cells, whereas in the absence of RU486, no significant activation was observed. There was a positive correlation between the luciferase activation and RU486 concentration in a definite range. The results showed that the RU486-inducible regulatory vector was successfully constructed, which can be used to regulate the expression level of genes of interest in appropriate time by the inducer RU486. This inducible expression vector provides a platform for the research of gene regulation and gene therapy.

加入诱导剂RU486后，可以诱导表达荧光素酶，并在一定范围内两者呈正比，最高可以实现荧光素酶的40余倍的表达，而没有RU486时，几乎没有报告基因的表达，表明RU486诱导调控载体构建成功，可实现对目的基因的表达时间和表达水平的精确调控，为进一步的基因调控研究和和基因治疗提供了良好的工具。

Two new chiral salen-manganese complexes were synthesized and employed in the enantioselective epoxidation of indene in the presence of pyridine N-oxide and ammonium acetate as cocatalysts, respectively.

合成了两个新型的手性salen-manganese配合物，在分别以吡啶氮氧化物和醋酸铵为助催化剂的条件下，运用于催化茚的不对称环氧化反应。

This article, by presuming the representative scenario and supposing in reason, proposes a method of binomial accumulation OS-CFAR（Order Statistics-Constant False Alarm Rate） detection algorithm in the presence of sector-region searching mode by accumulating irrelevantly the radar echoes in every dwell interval.

针对反舰导弹末制导雷达常用的扇形搜索方式，提出一种二项式积累OS-CFAR检测算法。

In such reigns, nothing veils the shame; and those who make examples, Tacitus as well as Juvenal, slap this ignominy which cannot reply, in the face, more usefully in the presence of all humanity.

在这些朝代里耻辱是不加遮盖的，塔西佗和尤维纳利斯这些表率人物，在人类面前有益地批颊痛斥这些无可辩解的耻辱。

In the presence of a well-reinforced step-up response, good conditioning to restraint, cooperation for flapping exercises, and aggression-prevention strategies by human companions, I believe that a macaw in a well-planned environment requires no more time or attention than, for example, a yellow nape.

在一个良好的－加强的－加速的反应，良好的调节控制，练习拍打的协调，人类同伴侵略的预防策略，我相信，在一个精心策划的金刚鹦鹉的环境，不再需要更多的时间或注意力。例如，一只黄颈鹦鹉。
