Abstract
采用双抗夹心酶联免疫吸附法(DAS-ELISA)对44个兰花病样分别检测建兰花叶病毒(Cymbidium mosaic virus,CyMV)和齿兰环斑病毒(Odontoglossum ringspot virus,ORSV),结果显示,有59.1%的兰花检出CyMV,36.4%的兰花检出ORSV,22.7%的兰花复合感染了CyMV和ORSV。采用一步逆转录聚合酶链式反应(RT-PCR)对24个兰花病样进行检测,结果有83.3%的兰花检出CyMV,75%的兰花检出ORSV,66.7%的兰花复合感染了CyMV和ORSV,可见RT-PCR检测灵敏度高于ELISA。

Pretraining has recently greatly promoted the development of natural language processing (NLP)We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performanceWe propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generationThe model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in ChineseExperimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performanceUpload PDF to Generate Summary
