basal body

also called Wool matrix (kinetosome)。

The matrix is cilia and Flagellum Of Microtubule tissue The center is a 9 (3)+0 structure, but the matrix only contains one Centriole Instead of a pair of centrioles (responsible for cells mitosis ）。 Matrix Kinetoplast (kinetosome), responsible for the synthesis of flagella and cilia.

Protozoa The swollen part of flagellum and cilia base. It is cylindrical, and its structure is basically similar to that of flagella or cilia, but it does not cover the cell membrane, and there are no two central lines microtubule 。 The matrix of flagellates such as Euglena is usually Root filamentous body And Nucleus It can be seen that the activity of flagellum is controlled by the nucleus. Some species Mitosis When, the matrix starts Centrosome Role of. a ciliate The matrix of class is often called Moving body 。 Each matrix emits a cilia Surface membrane The matrix is arranged in rows and formed by original specialization Filamentous connection , impulse conduction, coordination cilia Activities of. Others Multicellular animal There is also this structure.

matrix

Play a bonding role in composite materials Reinforcement One of the main components that become a whole and transmit loads to the reinforcement.

The matrix is basically distinguished according to the category of raw materials, namely high polymer (resin) based, metal based, ceramic based Glass And Glassware and Ceramics Base, carbon base (including graphite base) and cement Basic, etc.

The polymer (resin) base can be divided into Thermosetting polymer Base (e.g epoxy resin 、 Unsaturated polyester and polyimide Etc.) and Thermoplastic polymer Base (such as various general-purpose plastics and Polyether phenol 、 Polyphenylene sulfide , PEEK and other high-performance varieties). Polymer (resin) matrix is widely used in composite materials, and its process is mature, especially thermosetting Polymers have a long history of use, but generally can only be used below 300 ℃. Metal matrix Commonly used are Al, Mg, Ti, etc, Superalloy and Refractory metal It is also on trial. Their operating temperature ranges from 400 ℃ to 1100 ℃, but the process is not yet mature. The glass and ceramic matrix are still in the experimental stage, and the process is very immature, but because the use temperature range is 600~1400 ℃, it is very attractive. The service temperature of carbon (graphite) matrix can exceed 2000 ℃ under the condition of oxidation resistance measures. Cement matrix It has a short history of being used for composite materials, but is expected to become a large amount of Material Science 。 By building the matrix and perception Optical fiber The quantitative relationship of strain can eliminate the strain transmission error and improve the test accuracy^[1] 。

stay X-ray fluorescence analysis In, the matrix is Analysis Elements The whole sample 。 Therefore, in the Multielement system The matrix of the same sample is different for each analytical element in the sample. And the matrix matching method is used to determine the casting kirsite The relative error of Chinalco is less than 0.4%^[2] 。

matrix (matrix palaeosome, palaeosome) is also called palaeosome and mesosomes. In the rocks with weak migmatization, they can be generally divided into Metamorphic rock "Matrix" and newly formed“ Vein body ”Two parts. The matrix basically represents the composition of the original metamorphic rock, generally Dark mineral More, sometimes due to Metasomatism Can change to a certain extent, such as coarsening of particle size Felsic Increase Hornblende happen Biotite Chemical, etc. With the increase of migmatization, the boundary between matrix and vein body gradually disappears.
