The invention belongs to a front end switching technology of an Ethernet switching system, in particular relates to a high-efficiency group-broadcasting repeat method based on a sliding window in a shared storage switching structure. The method adopts an optimization way outputting the sliding window and no longer uses a strict FIFO-type cell to make a repeat, but selects a suitable cell to make the repeat in a certain range (window width). The repeat way obviously decreases the repeat span of a group-broadcasting cell, thereby decreasing the stay time of the group-broadcasting cell in a shared storage area. The method has two most direct advantages that the method increases the synchronous level of the group-broadcasting cell repeat at every goal port, and lowers the consumption to a shared storage room. An analogue result shows that selecting the suitable window width can effectively increase the performances of the system at the two fields, but excessively widening the window width can not limitlessly increase the performances of the system, on the contrary, can increase the count complication.

The present invention provides a detector for a chromatograph capable of obtaining the accurate retention time, even if there is a frequency deviation of the clock signal for determining the timing of data sampling, by conforming the progress of the detector internal time accompanied with the repetition of the sampling to that of real time. In the detector, consecutive data sampling intervals are defined to be a time adjustment period, and in one time adjustment period, each of the sampling intervals whose number is given as the interpolation value M is elongated by a predetermined number of clock counts compared to each of the other sampling intervals. If the clock signal has a positive frequency deviation, the apparatus internal time determined by the clock signal progresses faster than real time. However, providing the interpolation value M corresponding to the amount of the frequency deviation elongates the time adjustment period on the basis of the apparatus internal time, to be conformed to the time adjustment period on the basis of real time which is determined by the sampling period.

The invention discloses a regulating method of cell cycle synchronization of haematococcus pluvialis. The method includes the following steps that mature haematococcus pluvialis chlamydospores synchronously germinate to produce red flagellated cells in a nitrogen limited culture medium and in the presence of strong light; the red flagellated cells undergo synchronous sporangium formation to form chlamydospores, and the process repeats periodically to realize that the haematococcus pluvialis is in the synchronous growth state in multiple cell cycles. The invention further provides an application. The application includes that the mature haematococcus pluvialis chlamydospores are put in the nitrogen limited culture medium, strong light and air rich in carbon dioxide are provided, and the chlamydospores form chlamydospores again via synchronous germination and synchronous sporangium formation; part of the formed chlamydospores are harvested directly while the other part is added into a new culture medium for continuous culture; periodically repeated culture is conduced according to the method. The method is simple, haematococcus pluvialis cell masses high in synchronization degree in multiple cell cycles can be obtained, and haematococcus pluvialis chlamydospores high in astaxanthin content can be obtained quickly.

The present invention relates to a device and a method for synchronizing an image capture device with a first image data set. The image capture device is used for recording a second image data set of a periodically moving area or object. Each first image data set contains information as to the point in time, relative to the periodically moving area or object, when recording took place. The device additionally acquires periodically recurring, current information of the area as well as information concerning the recording instant of the first image data set. From the periodically recurring information and the recording instant of the first image data set, a triggering instant is derived which controls at least one recording of the second image data set by the image capture device in such a way that the second image data set contains image data synchronized to the first image data set.
