In addition , with a mountainous area and inland , long - term anoxic , lack a few microelement ( if be short of iodic ) , affect adolescent to grow thereby growth level , also have particular concern 此外，与内地、山区长期缺氧、缺乏一些微量元素(如缺碘) ，从而影响青少年生长发育水平，也有一定关系。

The results show that : blm can rapidly form on the tip of the electrode and is kept for a long time ; the test results can recur in the manner described and the blm modified by 2 has the selection of iodic ion 结果表明： blm完全可以形成于用该方法处理的金属表面端，能在一段时间内保持稳定，并能在相同实验条件下再现同样结果，经碘修饰的blm还能选择性的识别碘离子。

Law of coloring of change orchid family name , can be bacterial cent two kinds big : use method of this kind of coloring , it is to use gentian to catch a bug first , all bacteria caught purple , besmear again next with iodic fluid , will strengthen the tie of dye and bacterium body , the alcohol of 95 comes to reoccupy decolour 20 30 seconds , some bacteria not by decolour , still withhold purple , some bacteria are become by decolour colorless , reoccupy answer is red finally answer catch 1 minute , the result already was caught by the bacterium of decolour cheng gong is lubricious , not the bacterium of decolour still keeps purple , no longer chromatic , such , every is caught purple bacterium calls bacterium of positive of change orchid family name ; ran chenggong calls bacterium of negative of change orchid family name lubriciously 革兰氏染色法，能够把细菌分为两大类：采用这种染色方法，是先用龙胆紫来染病菌，所有细菌都染成了紫色，然后再涂以碘液，来加强染料与菌体的结合，再用95的酒精来脱色20 30秒钟，有些细菌不被脱色，仍保留紫色，有些细菌被脱色变成无色，最后再用复红复染1分钟，结果已被脱色的细菌被染成红色，未脱色的细菌仍然保持紫色，不再着色，这样，凡被染成紫色的细菌称为革兰氏阳性菌；染成红色的称为革兰氏阴性菌。
