一般"大量的""重大的"会用a great number of 、a great amount of 、a plenty of 、great等，这些表达都过于trivial ，用好substantial、considerable、significant 会对写作增色不少。
一、对于可数事物，用a considerable/substantial number of，例如：
A considerable number of GPUs are used in training the Large Model.（大量的GPU用于训练大模型。）
A substantial number of users outsource their data to the cloud. In this context, data auditing especially data integrity auditing has turned out to be a crucial requirement for users. （大量的用户将数据存在云上。在这种背景/情形下，数据审计特别是数据完整性审计就成为用户的关键需求。）
注意，虽然有a number of improvements/achievements，但不要用a considerable/substantial number of形容improvements 、achievements 等，那样有点过于夸张了。
二、对于improvement、achievement（一般是单数，有时复数形式）等、以及不可数事物，直接用substantial、considerable和significant 形容，例如：
Considerable/Substantial/Significant achievement in deep learning like image recognition and natural language processing opened the door to the AI era. （深度学习的大量/重大/显著成果（图像识别、自然语言处理等）打开了AI时代的大门。）
Considerable/Substantial/Significant improvement of performances in terms of ......renders the system applicable eventually.（......方面性能的大量/重大/显著改进使系统最终进入了实用。）
Considerable/Substantial/Significant investments are required for the ambitious plan. （这个雄心勃勃的计划需要大量投资。）
A considerable/substantial/significant decline in quality led to a disastrous result.（质量的大幅下滑导致了灾难性的后果。）
The institution received considerable/substantial/significant financial support but failed in its efforts to realize controllable nuclear fusion. （该机构获得大量资金支持，但是实现受控核聚变的努力还是失败了。）
As illustrated in Fig.5, the proposed scheme achieves considerable/significant improvement in efficiency of communication and computation compared with existing schemes.（如图5所示，所提出的方案在通信、计算效率方面比已有方案有显著改善。）
++The launch of the AI product Sora received considerable/substantial/significant attention++. （Sora的推出引起了广泛关注。）
上句中received 可以用attracted 、earned 代替。
三、避免在科技写作中使用enormous、huge和immense，这些一般是口语中带夸张语气的单词，和口语中absolutely等语气一样。
