positive ion

基本解釋

If one or more electrons are removed the remaining positively charged structure is called a positive ion .
如果移去一個(gè)或多個(gè)電子，剩下來帶正電荷的結(jié)構(gòu)就稱為正離子。
Objective To realize the significance of eosinophilic positive ion protein in asthma and its change at various stage.
目的了解嗜酸細(xì)胞陽離子蛋白在哮喘發(fā)病中的意義及臨床不同時(shí)期的變化。
Chitosan, as a nontoxic and natural high molecular positive ion flocculant, is of high safety and in possession of the functions of biodegradability, absorbability and hygroscopicity.
殼聚糖是一種無毒、安全的天然高分子陽離子絮凝劑，具有生物降解性、吸附性和吸濕性等作用；

And, we're going to look at what happens as the chloride ion moves from infinity in towards the positive ion.
然后我們要看一下,當(dāng)氯離子從無限遠(yuǎn)處逐漸靠近,這個(gè)正離子會(huì)發(fā)生什么。

If instead we had a positive ion, a cation, what we would have to do is subtract 1.
如果我們有一個(gè)帶正電的離子，一個(gè)正離子，那我們就需要再減去一個(gè)。

So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.
因此，基本上無論什么時(shí)候,只要我們有一個(gè)很大的正的電子親和能，這就意味著這個(gè)原子,或離子非常希望得到一個(gè)電子，如果它得到了，會(huì)變得更穩(wěn)定更開心。
