三氯乙酸终止液对木瓜蛋白酶酶活测定的影响研究

本实验研究了不同的三氯乙酸终止液,对木瓜蛋白酶酶活的影响。通过使用两种检测方法,不同配方的三氯乙酸终止液进行实验。结果表明,使用两种不同配方的三氯乙酸终止液所得的结果相差2倍多。用不同稀释浓度的三氯乙酸终止液,在高浓度时,不同浓度的三氯乙酸终止液得到的结果差别很大,随着三氯乙酸浓度的降低,所测得的酶活不断升高;但是在低浓度时,不同浓度的三氯乙酸终止液得到的结果差别不大。     

Generating Questions Based on Semi-Automated and End-to-End Neural Network

With the emergence of large-scale knowledge base, how to use triple information to generate natural questions is a key technology in question answering systems. The traditional way of generating questions require a lot of manual intervention and produce lots of noise. To solve these problems, we propose a joint model based on semi-automated model and End-to-End neural network to automatically generate questions. The semi-automated model can generate question templates and real questions combining the knowledge base and center graph. The End-to-End neural network directly sends the knowledge base and real questions to BiLSTM network. Meanwhile, the attention mechanism is utilized in the decoding layer, which makes the triples and generated questions more relevant. Finally, the experimental results on SimpleQuestions demonstrate the effectiveness of the proposed approach.
