解釋
負調節物,負調節蛋白-
Rlean meat percentage is one of the most important economic traints in pig breeding programs. myostatin is a negative regulator of skeletal muscle growth. null or low activity of myostatin, individual muscle of mutant amimals would show a large and widespread increase in skeletal mass. myostatin null animals have significantly larger diameter or more quantity of fiber skeletal muscle. the phenotype was termed double muscling. in order to probe the relation between myostatin and high lean meat rate and plump - hipped trait, we sythesized the c ' 80 amino acids coding sequence of porcine myostatin and costructed the cloning and expressing vector of it
肌生成抑制素（ myostatin ，即mstn ）是近幾年來（ mcpherrona . c等， 1997 ）發現的骨骼肌生長的負調控因子，它主要在骨骼肌中表達。其活性的喪失，會引起動物肌肉的過度發育，肌纖維直徑變大或肌纖維數增加，表現為雙肌癥狀。肌生成抑制素研究的突破將對豬、肉雞、肉牛等畜禽生產性能的提高具有特別重要的意義。 -
The objectives of this study are to clone the ban fragment of brassica napus and to apply the floral - dip in the transformation of oilseed rape to establish a convenient method for oilseed rape breeding. ban is dfr - like gene in chalcone synthesis pathway functioned as a negative regulator, and has been well studied in arabidopsis thaliana
為利用轉基因技術創造甘藍型黃籽油菜，本文克隆了與甘藍型油菜（ brassicanapus ）色素生物合成有關的ban基因同源片段，並探索了甘藍型油菜花序浸泡法轉基因新方法。 -
To reduce the high starting current as asynchronous motors start up directly and eliminate the negative influence that brought about by switching of contact when it starts up with reduced - voltage means, two new methods based on power electronics technology for improving the starting characteristics of three - phase induction motor are presented. one is alternative voltage regulator, the other is alternative voltage chopper. the three - phase regulating circuit - asynchronous motors system and the three phase chopper circuit - asynchronous motors system are analyzed and simulated with matlab
為解決上述問題，本文提出一種基於斬波方式的三相交流異步電動機的軟起動新方法，論文對電路的起動特性、功率因數、諧波以及控制策略進行了研究，模擬結果表明這種基於斬波方式的三相交流異步電動機的軟起動方法比基於三相交流調壓的三相交流異步電動機的軟起動方法具優越性。 -
But a series of research hint that it may be a negative regulator in cell cycle regulation
但現有的研究提示它可能作為負性調節因子參與細胞周期調控。 -
Network opinions is a regulator which has negative as well as positive influence on the development of " three outlooks ". in order to delete or minimize the negative influence we can take the following measures : to educate the students with correct ideological and political theories ; to regulate the management of network opinions, set up relevant laws and eliminate rubbish information ; to strengthen network education and promote self - restrain
為了應對網路輿論對大學生「三觀」形成的負面影響，可從以下幾個方面著手克服或削弱網路輿論帶來的負面影響：思想政治教育進網路搶占陣地、搶占對象，用正確的理論武裝青年大學生頭腦；正本清源，進行網路立法、網路管制，掃除信息垃圾；加強對大學生的阿德教育，促使網上自律和他律相結合。
