Although hydroxyl radicals are degraded by pollutants, says Rohrer, some of these same molecules also help to recycle OH.

雖然氫氧自由基因為消滅污染物而減少，Rohrer說国产高清怕怕怕视频在线观看，但是也有些相同的分子能幫助它們再生。

Because a molecular is the rotatable charge group, there is an attraction force between molecules.

因為分子是能自由旋轉(zhuǎn)的電荷群，所以分子之間存在相互吸引力视频一区视频二区国产激情。

In the case of low doping concentration of porphyrins and long interchain distance, the rotational motion of porphyrin molecules is the main reason of fast luminescence decay and low luminescence efficiency.

The temporal effect is said to occur while sample molecules are passing a fixed-position detector. Since the sample dispersion keeps changing during the monitoring, the signal recorded should be different from that of the true sample distribution in the flow.

所謂時間效應(yīng)是指樣品在管路里流動時大屁股91，由於在管中產(chǎn)生的分散現(xiàn)象r日本在线h，會導(dǎo)致樣品在通過偵測器之時，樣品的分布會因流動而改變久久亚洲精品无码a∨，因此所測得樣品之訊號和實際樣品之分布并不相同中文字幕一区2区。

British biochemists Sanger invented RNA and DNA molecules identified in the order of the base technology.

英國生物化學(xué)家桑格發(fā)明了確定 RNA 和 DNA 分子中堿基排列順序的技術(shù)。

Normally, to be tasted, a potentially sapid or instable substance must go into solution upon coming in contact with saliva, which limits instable chemicals to watersoluble molecules.

正常來說国产特级黄色操逼毛片，要是嘗的話快射视频十八禁网站，一種潛在的美味或者不穩(wěn)定的物質(zhì)必須在進入嘴與唾液接觸之前變成液體。這也就限制了不穩(wěn)定的化學(xué)物質(zhì)為水溶性分子少妇被又大又粗进进出出。

Background— Caveolae, lipid-rich microdomains of the sarcolemma, localize and enrich cardiac-protective signaling molecules.

The interaction of chemical molecules and biological ones, especially sequence specific recognition and site-specific cleavage of DNA have many applications such as in DNA sequence determinations, chromosome analyses, gene therapeutics, and recombinant DNA manipulation. So it is significant to develop artificial enzymes for the scission of nucleic acid with high activity and selectivity at normal condition.
