求翻译：八十年代，当他开始研究量子宇宙论时，他的行动已经出现问题。经过一系列的治疗后，他却再不能说话了。现在他全身瘫痪，要靠电动轮椅代替双脚，不但说话和写字要靠电脑和语言合成器帮。是什么意思？

In the eighties, when he began to study the quantum cosmology, his actions have a problem. After a series of treatment, he was again unable to speak. The paralyzed rely on the electric wheelchair instead of feet, not only to speak and write to rely on computer and speech synthesizer to help.

1980s, when he began to study quantum cosmology, he has a problem. After a series of post-treatment, but he can no longer speak. He is now complete paralysis, have to rely on an electric wheelchair for your feet, not only to speak and write on your computer and synthesizer language help.

The 80 's, when he started working on quantum cosmology, and his actions have problems. After a series of treatment, he was unable to speak. Now his body paralyzed, depends on the power wheelchair in place of feet, not only speak and write on computer and voice synthesizer.

80's, when he starts studies the quantum cosmogony, his motion already has the problem.After a series of treatments, he again could not speak actually.Now his whole body paralysis, must depend on the electrically operated wheelchair to replace the both feet, not only speaks and writes must depend on
