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〉

The research team proposed the intelligent predetermined control rules. The advantage of the complex control change into simple control and the actuator for independent actuation. Reducing actuator interfere with each and energy-saving. 
In order to realize the intelligent predetermined control rules used in the environmental chamber. Design a fineness decreasing temperature and dehumidification system, that combines the characteristics of moist air in the chamber are estimated, and a control path planning. It directly control of the required amount of heat and dehumidification in no-load conditions to achieve precise control.
Temperature and humidity control path planning into step signal, ramp signal and sin signal. Get air change control path according to the three maximum and minimum cooling capacity and dehumidification capability. When the chamber temperature changed and the chamber wall will absorb or release heat. Construction of thermal heat transfer equivalent model to calculate the chamber wall heat absorbed or released.
When finished calculate the air changed energy and the chamber wall heat absorbed or released. Heat transfer can be used to design the evaporator and condenser, and the selection of a compressor, an expansion valve and other control elements.
