Among those hydrogenbonding residues, Tyr119, His227, Asn392 and Leu451 could form hydrogen bond with the benzofuran inhibitots and Tyrl07, Asn175, Thr211 and Asp412 were newly discovered hydrogen-bonding residues, which were highly conserved residues across the NMT family and would play an important role in the design of NMT inhibitots with novel chemical scaffold.

CaNMT活性位点发现有两个氧键作用区域，其中Tyrll9，His227，Asn392和Leu451是与已有抑制剂的氢键结合位点，Tyr107，Asn175，Thr211和Asp412是新发现的氢键结合位点，而且在NMT家族中高度稳定，它们对设计新结构类型的CaNMT抑制剂具有重要作用。

For example, H, atomic weight of 100,794 hydrogen, carbon FC atomic weight of 1201, the atomic weight of oxygen O for 1594, Copper Cu for F63546 and so on. F history, had also used the other two kinds of "benchmarks", and there have been two kinds of scales used in parallel .1803 years, J Dalton published the first atomic table, the hydrogen-quality of the original F son as a "benchmark "requiring H, atomic weight is 1. In 1826, JJ Berzelius Tony F are presented to the quality of 116 oxygen atoms O as a" baseline "(scheduled for O, E atomic weight 16), which is has been in use to 1961 "Oxygen unit." 1929, found that the oxygen in nature, in addition to the greatest abundance of 16O, there are a small amount of slightly heavier 17O and 18O two kinds of isotopes, and the different sources of oxygen, its composition is slightly different.

例如氢H的原子量为100794，碳FC的原子量为1201，氧O的原子量为1594，铜Cu为F63546等。F历史上，还曾用过另外两种"基准"，并且有过两种标度并行使用。1803年，J道尔顿发表的第一张原子量表，把氢原F子的质量作为"基准"，规定H的原子量为1.1826年，JJ贝F采利乌斯提出，以氧原子O质量的116作为"基准"（定O的E原子量为16），这就是一直沿用到1961年的"氧单位"。1929年发现，自然界中的氧，除丰度最大的16O以外，还有少量稍重的17O和18O两种同位素，并且不同来源的氧，其组成也稍有不同。

Experimental results show that hydrogen can be produced by the reaction between nitric acid with a given concentration and aluminum handled by means of mercuric bichloride solution under room temperature. Whereas hydrogen is not detected without aluminum handled by mercuric chloride solution.

研究发现，室温下用去膜并经氯化汞溶液处理过的铝箔与一定浓度的稀硝酸作用可产生氮气，而未经氯化汞溶液处理的铝箔与稀硝酸作用几乎检测不到氮气的生成。
