With the development of embryo, Myf5 expression decreased gradually in somites in the anterior region, but remained strong in the newly formed somites; After 30 somites formed, MyoD expression decreased in the somites except the caudal somites. At the hatching stage, MyoD and Myf5 were expressed in head muscle cells and fin muscle cells. In the growing fish, Myf5 was expressed in the skeletal muscle and intestine, and in adult flounder, Myf5 was only expressed in muscle. In the growing fish and adult fish, MyoD was only expressed in muscle.

在胚胎发育早期，Myf5在近轴中胚层中表达，体节发生过程中，Myf5在体节中表达，MyoD基因最早在分节板的体节前细胞中表达，随后在近轴细胞、体节中表达；随着胚胎的发育，Myf5在成熟体节中表达量降低，在新生体节中表达较强；MyoD自30个体节时期后只在新生的尾部体节中表达，在成熟的体节中表达量降低；在孵化期，MyoD和Myf5在头部及鳍的肌肉、尾部的体节中表达；生长期的牙鲆中，Myf5在骨骼肌和肠中表达，成体牙鲆中，Myf5只在肌肉中表达；生长期的牙鲆及成体牙鲆中，MyoD只在肌肉组织中表达。

Milling groove machine is used in processing weaving trade in " pin plate " use privately cut machine tool, belong to the modular machine tool, this machine tool have 4 works position and 8 milling heads, can at the same time process 8 workpieces, have higher processing efficiency and processing precision, and can at the same time still realize needle groove and circular arc groove same work position, it surmounted the shortcoming of that machining process complex, processing efficiency low and process precision do not be in height of the processing of pin plate beforetime, so it have better application prospect.

铣槽机是用于加工纺织业中&针板&的专用切削机床，属于典型的组合机床，该机床具有四工位、八铣头，能同时加工八个工件，具有较高的加工效率和加工精度，同时还能实现针槽与圆弧口槽同工位一次完成，克服了以前针板加工中加工工序复杂、加工效率低、加工精度不高的缺点，有较好的应用前景。

The method includes the steps of: suspending the filtration operation; performing a cleaning process on the membrane wall to dislodge contaminant matter from the membrane wall into liquid surrounding the mem brane: performing a sweep of the feed-containing vessel (6) substantially parallel to the longitudinally extending membranes (7) to remove the liquid containing the disloged contaminant matter, at least in part, through the openings (10) in the header (8, 9) or, where only the upper header (8) is used, through an opening (12) in the module, and then recommencing the filtration operation.
