Abstract.
The structure diagram of the algorithm is shown in Fig.1 Fig.1 Heterogeneous PCA Selective Ensemble Learning Algorithm Extracting Key Factor of Supply Chain Performance To approve the reliability of the algorithm, this thesis analyzes the time performance data of supply chain for C Company and extracts its key influencing factors.
The indicators of time performance include the cycle of raw material purchase(A), average manufacturing cycle(B), average distribution time(C), financial decision time (D), time of purchase plan formation (E)and time of production schedule formation (F).
And the final computed result is shown in Fig.2 Fig.2 Key Factors of Supply Chain Time Performance According to the figure, it is clearly seen that the key factors of supply chain time performance at C Company in 2007 were average manufacturing cycle and main raw material purchase cycle, whose key degree is higher than others, among which the influence of average manufacturing cycle is much higher than other factors, so it is the key object which needs to be monitored in the supply chain.
In order to prove the effectiveness of the algorithm, this thesis adopts K-means cluster to analyze the six indicators of time perforce A~F as well as the original data set of key factors obtained by selective ensemble learning, i.e., the original data set of main raw material purchase cycle (A), average manufacturing cycle (B)and time of production schedule formation (F).

Abstract.
The Reverse Engineering Technology (RET) is extensively employed in the realm of product designing.
The process includes three procedures: data measurement, surface reconstruction and product processing, among which CAD surface construction procedure is a key step but also a bottleneck problem affecting the speed of the Reverse Engineering project.
The flow chart of Reverse Engineering is shown in Fig 1.

In several fields of engineering the automation of the CFRP production chain is a major issue.
In fiber materials different deformation mechanisms exist.
From these very different materials, three material classes are mostly used by applicants.
For more complex deformations mode, like they exist e.g. in biaxial materials maybe a set of initial test has to be used, to identify the role of the two key modes within such materials.

Key words: lithium ion battery, Quality control points; Quality management
Abstract: with the advent of the era of 3 g, mobile phone has become a key factor restricting the development of mobile phone battery, lithium ion battery is still dominant used in mobile phone in the next four or five years.
In this paper,it has been analyzed that lithium ion battery parts, and does quality management of all engineering parts, mainly focus on the quality control of the Angle of the sealing plate, sealing body and the shell, at the same time deeply analyzes the different parts of the common categories .So this paper plays a guiding role in guaranteeing the whole project management of the quality of handset lithium battery.
Li+ are back and forth when charging and discharging, Li back and forth between are aligned .Namely when charging, Li+ changes from low energy materials to high-energy state through electrolyte migration from the positive to the negative terminal; when discharging Li+ are carried out naturally from negative of higher energy to the lower energy positive materials through the electrolyte, at the same time releases energy through external [5].
Currently, three components material of the liquid lithium ion battery that Ni, Co, Mn produces the high capacity battery 4.4 V, positive active material is Li (NiCoMn).
The common adverse categories of product engineering Fatal adverse Safety valve, leakage thickness of relief valve, shell cut; Serious adverse Size error of shell, sealing plate and sealing body, bad air tightness, sealing body deformation of sealing body and deviation, burr, compression, aluminum powder flake of each product, etc.; Slight adverse Play marks, scratches, depression, dirt, grease, watermark, damage to the bad appearance, etc Appearance quality control point of each engineering part in the production process The name of each part of the shell (As shown in Fig,1) The shell common injury: A mark, scratch ─ ─ the shell parts; Deformation ─ ─ open department; Sag ─ ─ positive, shell bottom; Shell cut/U word hurt ─ ─ shell parts; Burr ─ ─ openings.

The use of natural fibers turns engineering work more sustainable, since they are renewable, biodegradable, energy efficient and non-toxic raw materials.
These materials are widely used in numerous engineering projects such as the construction of embankments, roads, airports, reservoirs, canals, embankments and coastal protection works [1].
Synthetic fibers are currently the most used in geotextiles for civil engineering where the physical and chemical properties and durability are key requirements of the applications.
