Result Analysis

4. Introduction.
In this study, the main data source of analysis was derived from the WOS (including SCI & ISTP) database and Engineering Village (EI) database. The retrieve word was the name of the institute, the retrieve time period starts from 2006 to 2010 and the retrieve time is September 1st, The total effective number of the thesis involved is 428.

5. Introduction..
The data source came from WOS and EI, and the publish time span is from 2006 to 2010, updating in July 30, Data in this study was required on Sept 1st, 2010 using the Address= “Ningbo Inst Mat Technol & Engn” selecting “all the years”. Totally 231 articles are gotten from the database as SCI-Expand and 27 articles as ISTP, which called Conference Proceedings Citation Index-Science (CPCI- S) now. For EI part, we turned to expert search of EI- compendex database using author affiliation retriever in all forms of NIMTE stored in Engineering Village Database and got 169 articles at last. Because of the limitation of the retrieval time, the data in 2010 is partial.

6. Data and Methods Number of Articles Number of Patents
Methods: using the subjects, collaboration(co-author ), publications, time-cited, co-words, cluster analysis

7. Number of Articles
AARG 93%
Fig.1 shows the number of SCI & ISTP articles acquired from WOS and EI during the period of 2006 to The total number of WOS articles from 2006 to 2000 is 428. From been established, the number of articles increased obviously and the increase rate is about 93% in average from the year of 2006 to 2009.

The Number of Patents can show the scientific level of an institute
and it's investment in innovate.
Applicants= Ningbo Institute of Material Technology and Engineering
The patents date was collected from China intellectual properties net using the CNIPR software to analysis. The retrieve word was designed as applicants（申请人） = Ningbo Institute of Material Technology and Engineering in Chinese form. Totally 123 patents were got from the State Intellectual Property Office of the P.R.C database among the year 2005 to 2010.（the pink line）
NIMTE seeks to realize the industrialization(实现产业化) of scientific and technological achievements by its authorized patents. So this institute expertise in materials research and engineering serves to address the diverse needs of industry ranging from research and development programs. It can be seen from figure 2 that the patent application increased sharply after 2007 and the authorized patents also rose greatly after Nearly 50 patents were applied or authorized recently.

9. Research Subjects Fig3. Distribution of the Research Subjects
Usually, more then one research field was hold in most institutes majoring in science & technology in all over the world. NIMTE have six business unites such as polymers and composites, magnetic materials and advanced devices, surface engineering & remanufacturing, functional materials and nanodevices, fuel cell & energy technology and fibers.
From figure 3 we can conclude that most published papers concentrated on materials, physics and chemistry science of common subject catalogue. That is because most NIMTE researchers’ education background involves in the above branch of learning so they are more familiar with them.

10. International cooperation
International cooperation is an important component of science and technology research activities and it has played an important role in promoting S&T(science and tech.) advancement of an institute. International cooperation be propitious(有利于) to research program to get timely informed about the material development trend in the world. NIMTE has paid an extraordinary attention to it and have already achieved great successes. NIMTE involved in diverse international activities, such as cooperate with U.S.A, Japan and Australia, actively communicating with world-famous institutes. Figure 4 was come from the NIMTE homepage showing their contact with the outside research organizations.

11. research organization
From the SCI article we can also found that its authors from China have a strong connection with the advanced research organization in turn from USA, Japan and Australia, et al. This kind of collaboration leaded to demotic research in CAS improve rapidly to the world class research level.

The dates showed which famous experts were being followed and cited by NIMTE authors as in table 1, taking INOUE A for example, who came from Kyushu University in Japan, is one of the authorities in magnetic material research of the world.

13. Figure 6. Number of SCI Articles Time Cited
There are 231 SCI articles published from 2006 to 2010, among which many thesis were cited by other papers. And 1 to 5 time cited articles take part in 37%, 6 to 10 is 3%, 11 to 15 is 3% as in figure 6. It is significant that the most cited article was cited 35 times, which published in LANGMUIR, 23 (19): on SEP , and the work is mainly involve in silver hierarchical(分层 ) bowl-like array.
Figure 6. Number of SCI Articles Time Cited

14. Figure 7. Number of Articles in SCI,ISTP,EI by NIMTE researchers
Some experts of NIMTE published excellence work on SCI covered journals for many times since joining in the institute. Others published their papers in the journal included in EI, as they concern more about engineering problems in their research work.
It can be seen that more than one scientist published over 20 SCI articles and over 10 EI articles in figure 7, which showed that some scholars whose achievements were so fruitful and NIMTE attract some hardworking experts since been established.

15. Figure 8. Clusters and Co-words Map of SCI Articles
Keywords are the main subject of one research paper concentrate on and through which one could clearly understand the topic or main idea of the publications. By this kind of analysis it can be found that NIMTE lucubrate(深入研究) on the microstructure & nanostructure materials these years, the ZnO or magnetic material(coword:coercivit矫顽磁性[kəuə:'siviti]) will become the next hotspots(热点) the NIMTE scientists concentrate on.

16. Patents
Patents can reflect the timely scientific progress of a research organization, and authorized patents are more likely going into the business application.

17. Patents Fig9. Distribution of the Research Subjects
the patent mainly concentrates in exploring the technology on: “class C: Chemistry, Metallurgy” “class H: Electricity”
IPC international patent classification.
The research field owning most patent distributed on coating(涂料) technology (C23C), cell preparation (H01M) and organic polymer (C08G).

26. In this paper, the bibliometric analysis and knowledge mapping were applied to research the scientific productivity of SCI, EI, ISTP articles and patents of NIMTE, CAS from to The published papers and applied patents grown rapidly during these years and the paper authors took extensively collaboration with many research organizations of the world. Some research subjects such as microstructure or nanostructure lead the main research field of NIMTE. The institute has already formed five patents group in past few years which can be illustrated from the knowledge map and bibliometric analysis results .
