由于传播方式的不同、审查机制的介入、意识形态的影响、语言规范和文学规范的改变以及写作者艺术完善方面的要求等等原因,许多新文学作品在作者有生之年及作古之后出现了众多版本.在不长的时间里,其版本密度之大,为中国文学史乃至世界文学史所少见.这些版本不只是版次的不同,更主要的是内容性的改变.这些改变是全方位的,既涉及版本内容,更涉及作品的思想、艺术诸方面.其中蕴涵着版本学、创作学、艺术学、语言学、修辞学、传播学乃至政治学、社会学等方面的意义.新文学版本变迁之复杂、蕴涵之丰富,为我们进行多角度的研究提供了可能.从文献学的意义上讲,一部具有众多版本的新文学作品就是一个变动不居的综合性的文献载体,具有重要的研究价值.

In this paper, we investigated the effects of error-feedback noise shaping(EFNS) on a lowresolution Kramers-Kronig(KK) detection system for the first time. Both 16-ary quadrature amplitude modulation(16-QAM) and 64-ary quadrature amplitude modulation(64-QAM) were considered in the experiment. The carrier tone was added on the transmitter side using the virtual carrier-assisted single sideband(VCA-SSB) method to meet the minimum phase(MP) condition. Under the MP condition, KK detection only needs the intensity of the optical signal to be detected by one photodiode(PD) to retrieve the phase information. However, the virtual carrier tone increases the carrier-to-signal power ratio(CSPR), which results in a high peak-to-average power ratio(PAPR) at the transmitter, causing an increase in quantization noise. To mitigate quantization noise in the low-resolution KK detection system, EFNS was applied. The application of EFNS increased the optimal CSPR of the KK detection system and improved receiver sensitivity. Using a 4-bit DAC and the EFNS, 80 km transmission was achieved in the 60-Gbit/s 64-QAM KK detection system.

Number and quantities of reference standards (RS) needed for the quality control of drugs are increasing, bringing great pressure to the calibration and using company. This manuscript summarized the four generations for the development of RS including physical RS, paper atlas, substitute RS and electronic databases. The advantages and disadvantages of each generation were summarized. The concept of digital RS (DRS) was proposed based on this, and summed up the definition, advantages, and technical architecture of DRS. The 10 characteristics of five aspects of the DRS were discussed including digital, multi-dimension, big data, cloud computing, internet, internet of things, sharing, multi-terminal, intelligence, and compliance certification. Then, the necessity of its formation and application in the medicine holistic quality control of internet plus era was discussed in this manuscript.
