It is an acrobatic display and historical play rolled into one changing and exciting panorama

它的表演是在一个丰富虚幻且可自行调节的场景中进行的。

The catalyst of the present invention is especially suitable for use in the conditions of low reaction temperature, high reaction pressure and high propylene load, may result in high yield of acrylonitrile, and may be used in industrial production.

本发明催化剂特别适用于在较低反应温度、较高的反应压力和高丙烯负荷条件下使用，且可保持高的丙烯腈单收，可用于工业生产中。

And I think the ACTA, or, again with its subculture of surveillance, encourages and is designed to, you know, put fear into people...

而我认为 ACTA 或其监视的亚文化，鼓励且被设计为，你知道，让人们恐惧。。。

BACKGROUND: Photodynamic therapy is a highly effective treatment for actinic keratoses; however, it is time consuming and often painful for the patient.

背景：光动力疗法是一种治疗化性性角化病非常有效的方法；但是，此疗法费时且常常引起患者的疼痛。

The new study included 21 healthy volunteers with sun-damaged skin and actinic keratoses -- skin lesions that could develop into skin cancer -- on their faces.

该项研究是针对21位志愿者展开的，他们脸部的皮肤均被晒伤且患有光化性角化病-一种可演变为皮肤癌的皮肤损害。

The calculation and analysis show that the sub-critical fast reactor is feasible for transmutation of minor actinides and can remain sub-critical when it adds some MA, it is feasible to choose the CDFR for the sub-critical fast reactor research.

计算结果表明：次临界快堆中加入MA后能够保持一定的次临界度且具有较好的嬗变效果，因此，选取示范快堆堆芯作为ADS次临界快堆的参考堆芯研究是可行的。

All are radioactive heavy metals; and only the first four (actinium, thorium, protactinium, and uranium) occur in nature in appreciable quantities. The other 11 are unstable and are produced only artificially.

这些元素都是具有放射性的重金属；仅前四个元素是在自然界中存在的，其余十一个都不稳定且均为人造的。

This suggests actinomycin D at certain concentrations could induce SL-1 cells apoptosis, which is much dependent on the concentration of dose of actinomycin D.

实验结果证明一定浓度的放线菌素D能诱导SL-1细胞凋亡，且成剂量正相关。

A novel sliding-mode control is designed with a load thrust observer for the Linear Permanent Magnetism Synchronous Motors,in order to compensate the disturbance and effectively minimize the system chattering;introducing an integral action in the sliding mode to eliminate the system error and chattering.

针对永磁同步直线电机提出了一种基于负载推力观测器的新型滑模变结构控制，从而实现对推力扰动的补偿，且大大削弱了推力纹波及系统的抖振；在滑动模态中引入积分环节来进一步消除系统的稳态误差和系统抖振。

Moreover, the development of course of disease and prolongation of period in the sunlight will further result in the decrease of MED of action spectrum.

且CAD患者病程的发展和户外曝光时间的延长会导致作用光谱MED进一步降低。

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。
