The present disclosure provides an optical image capturing lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex image-side surface; a second lens element; a third lens element; a fourth lens element, at least one of an object-side surface and an image-side surface thereof being aspheric; a fifth lens element, at least one of an object-side surface and an image-side surface thereof being aspheric; and a sixth lens element with negative refractive power having a concave image-side surface, at least one of an object-side surface and the image-side surface thereof being aspheric, at least one inflection point being formed on at least one of the surfaces thereof. With the aforementioned arrangements, the sensitivity of the optical system can be attenuated while the aberration and astigmatism can be effectively corrected to improve the image quality.

The invention relates to a data transmission method, which comprises the following steps that: duplicate resource data information of a resource file which is downloaded and distributed from the whole network is collected from the client, a push resource list and an abandonable push resource list are generated according to the downloaded and distributed duplicate resource data information of the resource file and are transmitted; basic information of the client when in running is acquired, whether the basic information conforms to a set push initial condition is judged, if the basic information conforms to the set push initial condition, a push request is transmitted, and if the basic information cannot conform to the set push initial condition, the push request is not transmitted; and a push task is returned according to the push request, and corresponding push resource is downloaded from a network according to the returned push task. In addition, the invention also provides a data transmission system. Due to the adoption of the data transmission method and the system, the download task is reasonably and initiatively pushed according to the basic information of the client, so the client stores and uploads the resource, the distribution of the resource on the network can be balanced, the utilization rate of the client network bandwidth can be improved, the peer-to-peer (P2P) download performance can be improved, and the server bandwidth can be saved.
