1、知识付费内容呈现方式分类

根据知识付费呈现方式,知识付费平台可分为社交问答、付费讲座、专栏订阅、社区直播等类型.

a.社交问答:内容生产者对用户提出的某个问题进行回答,平台从问答双发抽取相应的提成.问答类型有c2c的知识分享讨论、积分型、招标悬赏类型.其内容生产门槛较低,基本上人人可参与,相应的回答知识性参差不齐,用户黏性较低,以图文为主.比如常见的平台有知乎、分答、微博问答.

b.付费讲座:内容生产者自选主题进行单次内容分享,主要以音频、视频,辅之图文进行分享,用户试听后可自主选择是否付费购买.比如知乎live、豆瓣、分答小讲、十点读书等是典型平台.

c.专栏订阅:内容生产者推出长期的系列课程、讲座等.时间长达数月或整年,用户需要一次性购买.因此,这类课程通常价格高,但知识内容也更成专业性、系统性.如果课程优质,用户的黏性很高.比如这类平台有喜马拉雅、得到.

d.社交直播:内容生产者直接以音频或视频直播的方式进行内容分享,在开课前期需要宣传与预热,吸引部分用户报名购买观看.这类课程内容生产者与用户可直接沟通交流,互动性很高.代表性的平台有荔枝微课、千聊等.

based on this idea, during 2016-2018, the research team collected the flash in the device on a 24kev energy segment. During more than two years of operation, they saw 285 flashes. However, most of these signals can be explained. The device built in the deep underground can shield most of the interference above the ground, but a small amount of background noise from radioactive lead, krypton and other isotopes can still enter the device and collide with xenon atoms. Fortunately, researchers can distinguish these noise signals. Of the 285 signals, 232 are from background noise. The question is, what are the other 53 signals generated by?
