Comparative Analysis on Activity Patterns of CG between Lianyungang and Yancheng

[Objective] The reseamh aimed to contrast and analyze CG activity rules in Lianyungang and Yancheng. [Method] By using lightning location data, basic characteristics of lightning activities in Lianyungang and Yancheng both located at the eastem coast of Jiangsu were analyzed and contrasted. [Result] CG characteristics in Uanyungang and Yancheng were same, and negative CG was dominant. Monthly change activity rule of CG basically presented single-peak distribution, and peak value appeared in August. Monthly change of the lightning was drastic, and high- occurrence period was both in summer. Daily change trend of CG in the two sites was consistent. High-occurrence period of the lightning was in af- temoon and early morning, and occurrence frequency of the lightning in the morning was less. Spatial distribution of CG in Lianyungang and Yancheng was very uneven. Lightning activity in Lianyungang mainly concentrated in northwest and southeast areas of Donghai County and western area of Guannan County. Especially in Donghai County, it was the area where lightning strike density was the maximum. Lightning strike activity in Yanchang was more concentrated, and mainly concentrated in the west, namely near Jiangying Town and Louwang Town. Distribution characteris- tics of CG intensities in the two sites were same. Waveform changes of the positive CG in the two sites were slower than that of the negative CG, and current intensity concentrated from ＋ 20 to ~ 50 kA. [ Conclusion ] By contrasting and analyzing lightning activity rules in Lianyungang and Yanchang, we could share and complement data in the two cities better, and serve for routine lightning prevention and early-warning better.

Assessment of Patentability of Inventions Relating to "Rules and Methods for Mental Activities"

Examination of whether an invention is a patentable subject matter or not is one of the main parts of the patent examination. In the recently revised Guidelines for Examination a relatively major change has been made of the benchmark for the examination of inventions relating to "rules and methods for mental activities", for example, limiting the scope of application of Article 25.1 (2) of the Patent Law. As a result, the hitherto non-patentable subject matters are still excluded from patentability. That...
