The embodiment of the invention relates to an identification method of long flows and a measuring method of data flow and a device thereof, wherein the identification method of long flows comprises assuring term number of business flow to be 1, wherein each term is corresponding to a prior counting type Blum filter, doing hash calculation for each term, generating hash address of each prior counting type Blum filter which is corresponding to each term, searching for a counter which is corresponding to each hash address which is corresponding to each term, circulating a counter which is corresponding to each prior counting type Blum filter, and judging the business flow is one long flow if the value of each counter in each term is bigger than and is equal to a preset threshold value or circulating time of a counter corresponding to each term is equal to the number of the prior counting type Blum filter, and returning to the step of confirming the term number of business flow to be 1 after adding 1 to the value of each counter in each term. The embodiment of the invention achieves the identification and statistic to long flows which are on line in real time in high-speed network, and is suitable for flow measuring requirements in high-speed network.

The invention discloses a construction method for rapid hole alignment and posture adjustment of a prefabricated stand column. The method comprises the following steps of lifting the prefabricated stand column to be moved over a bearing platform, vertically arranging a plurality of embedded bars on the top face of the bearing platform, and vertically and correspondingly arranging a plurality of embedded sleeves inside the prefabricated stand column; utilizing a guiding conical clamp for clamping the embedded bars to guide the prefabricated stand column to fall gradually, enabling the embeddedsleeves to be accurately aligned to the embedded steel bars; removing the guiding conical clamp, when the prefabricated stand column falls down to the position, the preset height away from the top face of the bearing platform, utilizing direction regulators installed at the four edges of the top face of the bearing platform for horizontally pushing the prefabricated stand column, and precisely regulating the plane position of the prefabricated stand column so as to enable the prefabricated stand column to accurately fall down to the center of the bearing platform. The method has the advantagesthat in the lifting process, the prefabricated stand column can be rapidly arranged in place, and the trial lifting frequency and time in the lifting process are decreased; in the lifting process, the plane position and perpendicularly of the prefabricated stand column can be conveniently and precisely adjusted, it is ensured that the construction error is controllable, operation is easy, and thesafety risk is low.
