Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

To prevent the components from malfunctions due to impacts in the working environment, all the electronic and electro-explosive devices are demanded to pass impact simulation tests. Owing to technological progresses, traditional electrical igniters have been replaced by ignition-chips. To assemble the whole ignition system, ignition-chips are overlaid on the igniter heads and packaged in the compartment cases.  This innovative design is to integrate the ignition circuit by directly coating an Au thin film bridge on the igniter head with vacuum evaporation technique to fabricate the ignition device.
  Prior to manufacturing, impact tests are usually carried out to validate if this Au thin film bridge can sustain impacts in the working conditions.
  In this thesis, transient response of the innovative igniter head subject to high-G impact is simulated according to MIL-STD 883E specifications.
  The simulation results evidence that the igniter head could survive under 120,000 G extremely high impacts. Although the safety factor of the glass part is only slightly larger than 1, it which is still below the common CAE requirement of 1.5. In this thesis, placing a ceramics spacer beneath the filling glass can successfully improve the safety factor of the glass part to over 1.5 that which would effectively enhance the anti-impact capability.
