ABS chain and Ethereum
Differences:
1. The two instries are different
2. P2P factoring is mainly for the upstream suppliers of the supply chain to transfer the accounts receivable of core enterprises, P2P provides funds, or docking factoring companies
Supply chain ABS is asset securitization, which transforms accounts receivable into securitiesthe data of enterprise accounts receivable can often directly reflect the proction and sales scale, enterprise benefits, financial status and other information of the enterprise, which is closely related to the development and survival of the enterprise
In recent years, the accounts receivable of various instries in China remain high, which seriously affects the capital turnover of enterprises, and makes the enterprises in the debt chain unable to operate normally, struggling, and even going bankrupt Therefore, the management of accounts receivable has become a very important issue in business activities 
extended data
with the expansion of its own scale, the existing capital flow of P2P online lending platform is no longer enough to support the platform in technology research and development, increasing financial license, online lending system upgrade and other expenses, so they choose to be listed for financing. In the choice of listing channels, the head P2P platform often chooses Hong Kong or overseas listing instead of A-share listing, mainly considering the profit requirements, net profit level and waiting time of domestic listed enterprises
as of December 31, 2017, four Chinese P2P online lending platforms have been listed in the United States: Yiren loan was listed on the New York Stock Exchange in December 2015, and xinerfu, Hechun and paipai loan successively landed on the U.S. stock exchange in 2017
in addition, Lexin, the parent company of orange finance, a P2P online lending platform, was listed on NASDAQ on December 31. According to the judgment of zero one finance and economics, with the continuous maturity of China's Internet financial regulatory environment, more online lending platforms will choose to be listed for financing in the future
is a semi crystalline thermoplastic. It has high impact resistance, strong mechanical properties, resistance to a variety of organic solvents and acid-base corrosion. It is widely used in instry and is one of the common polymer materials. Australian coins are also made of polypropylene
PE: Polyethylene
is one of the most commonly used polymer materials in daily life, which is widely used in the manufacture of plastic bags, plastic films and milk barrels
polyethylene is resistant to a variety of organic solvents and acid-base corrosion, but it is not resistant to antioxidant acids, such as nitric acid. Polyethylene will be oxidized in oxidizing environment
polyethylene can be considered as transparent in the film state, but when the block exists, e to the existence of a large number of crystals in it, there will be strong light scattering and opaque. The degree of crystallization of polyethylene is affected by the number of branches. The more branches, the more difficult it is to crystallize. The melting temperature of polyethylene crystal is also affected by the number of branches, which ranges from 90 ℃ to 130 ℃. The more branches, the lower the melting temperature. Polyethylene single crystals can be prepared by dissolving HDPE in xylene above 130 ℃

ABS is a synthetic plastic of acrylonitrile, butadiene and styrene. It is a kind of resin with high strength, good toughness and excellent comprehensive performance. It is widely used as engineering plastics. In instry, polybutadiene latex or styrene butadiene rubber with low styrene content as the main chain is prepared by graft copolymerization with acrylonitrile and styrene. In fact, it is often a mixture of graft polymer containing butadiene and acrylonitrile styrene copolymer San (or as). In recent years, styrene and acrylonitrile were copolymerized first, and then mixed with graft copolymerized ABS resin in different proportions to prepare various ABS resins suitable for different uses. Instrial proction began in the United States in the mid-1950s
instrial proction methods can be divided into two categories: one is the mechanical blending of polybutadiene or styrene butadiene rubber with San resin on roller, or the blending and copolymerization of two kinds of latex; In addition, styrene and acrylonitrile monomers are added to styrene butadiene latex with low content of styrene butadiene or styrene, and then emulsion graft copolymerization is used or mixed with SAN resin in different proportions.
structure, properties and application in ABS resin, rubber particles are dispersed in the continuous phase of San resin. When impacted, the crosslinked rubber particles bear and absorb the energy, so that the stress is dispersed and the crack development is prevented, so as to improve the tear resistance
the purpose of graft copolymerization is to improve the compatibility and adhesion between rubber particle surface and resin phase. This is related to the amount of free San resin and the composition of San resin grafted on the main chain of rubber. The difference of acrylonitrile content between the two resins should not be too large, otherwise the poor compatibility will lead to the cracking of rubber resin interface
ABS resin can be processed into plastics by injection molding, extrusion, vacuum, blow molding and rolling, and can also be processed by mechanical, adhesive, coating and vacuum evaporation. Because of its excellent comprehensive performance and wide application, it is mainly used as engineering materials and household appliances. Because of its good oil resistance, acid resistance, alkali resistance, salt resistance and chemical reagent resistance, it can be used to replace some metals because of its good electroplating performance, good luster, light specific gravity and low price. It can also synthesize many varieties such as self extinguishing type and heat-resistant type to adapt to various uses.
ABS (asset backed securities) is called asset-backed securities. In a narrow sense, ABS usually refers to a financing tool that issues bonds to investors after the assets with predictable and stable cash flow, such as bank loans and enterprise accounts receivable, are packaged into an asset pool
MBS (mortgage backed securities) is called housing mortgage-backed securities. Its essence is the same as ABS, but underlying assets are mortgage loans for housing or commercial real estate. MBS procts account for more than 70% of the US asset securitization market
ABN (asset backed medium term notes) is essentially the same as ABS, but it is a private directional fund-raising from investors with a relatively short term. It has been issued in China
PPN (private publication notes) is a kind of non-public directional debt financing tool, which can only be circulated among a certain range of institutional investors by issuing debt financing tools to specific institutional investors (in fact, it is the agreed financing agreement). It has been issued in China
asset backed securities are issued by the trustee and represent the beneficial share of the trust for a specific purpose. The trustee shall bear the obligation to pay the income of asset-backed securities to the investment institution to the extent of the trust property. The payment basically comes from the cash flow generated by the asset pool supporting the securities. The assets under this item are usually financial assets, such as loans or credit receivables. According to their terms, payment is regular
the time of principal payment in asset-backed securities often depends on the time of principal recovery. The inherent unpredictability of the time of principal recovery and the corresponding time of principal payment in asset-backed securities is one of the main characteristics of asset-backed securities, which is different from other bonds. Assets that can be used as collateral for asset-backed securities fall into two categories: existing assets or receivables and future assets or receivables. The former is called "securitization of existing assets", while the latter is called "securitization of future cash flow"

2, the application of Fabs
program judgment filtering sampling signal, such as often by random interference sensor instability caused by serious distortion, can use this method. The method is: according to the proction experience, determine the maximum allowable deviation △ of two cross sampling ×, If the subtraction value of two successive sampling signals is greater than △ ×, It indicates that the input is interference signal and should be removed; Use the last sampling value as the current sampling value, if it is less than or equal to △ × It shows that there is no interference and the sampling value is valid. This method is suitable for sampling slowly changing physical parameters, such as temperature, physical location and so on
The difference between ABS and PC is that ABS is a common material with low price. PC is engineering plastics, the price is more expensive.
