It can improve the conflagrant properies of tobacco when cobalt joined, and the min-nim selenium can reduce the deleterious substance in the cigcarette haze, and reduce the harm to health,therefore in this paper we have researched the adsorptive properities of cobalt on tobacco and some factors which affect the adsorption of selenium on tobacco by the theory of liquid - solid adsorption . We have discussed the influences of the adsorbate concentration. temperature, pH and certain concomitant substance, and have determined adsorption isothermal under the different temperature.

微量元素钴的加入能改善烟丝的燃烧性能；微量硒的存在能降低烟气中有害物质，减轻吸烟对人体健康的危害，因此本论文利用固—液吸附理论研究了钴在烟草上的吸附性能以及硒在烟草上吸附的一些影响因素，探讨了吸附质浓度、温度、pH及某些共存物质对吸附的影响，测定了不同温度下的吸附等温线。

There is also evidence that Selenium has a protective effect against some forms of cancer; including lung cancer, colorectal cancer, prostate cancer, liver cancer , breast cancer, and so on common cancer.

Selenium level in HP-infected gastric mucosal lesions Was negative correlated significantly with Expression rat of CD44V6, C-met and PCNA ( P.05 ), but was positive correlated with expression rat of P16 (P.05). Conclusions Selenium can influence morphological conversion, and decrease hematolysis and effects the function of vacuole toxin of HP.

其原因可能是机体为保护性地对抗幽门螺杆菌感染所致增加的活性氧而动员硒，使组织硒含量增加，但由于随胃黏膜组织病变程度加重，硒消耗增多，使含量又相对降低；硒含量分别与CD44V6、C-met、PCNA表达阳性率呈负相关，而与P16表达阳性率呈正相关。

However, the selenium can relieve the damage to a certain limitation. During the cultivation of Potamogeton maackianus of rich selenium, the situation of heavy metal pollution should be checked in time so as to avoid the damage on fish caused by the heavy metals enriched in the bait.

然而，Se缓解Cd对黄丝草的毒害是有一定限度的，在富Se黄丝草的繁殖过程中，需及时检查重金属污染情况，防止重金属在饵料中的富集，以免造成对渔业的危害。

The native oxides on CdSe surface could be reduced to elemental Selenium by a HF etching process. Bombardment using 100eV Ar〓 ions with a dosage of about 1×10〓 ions/cm〓 could remove all the elemental Selenium, which results in a normal stoichiometrical surface CdSe.

实验观测到HF刻蚀可以将CdSe半导体表面的Se氧化物还原为元素Se.100eV的Ar〓离子轰击可以除去HF刻蚀后在表面还原生成的元素Se，从而清洁样品表面，保证了表面CdSe的化学计量比。

I've written before that approximately 2/3 of the earth's tillable soil is completely devoid of Selenium, a vital trace element and power mineral required not only for the production of SOD but also one that is a powerful immune booster, cancer fighter and longevity mineral too, that most people have virtually no selenium in their diet which is another great reason to make sure that you're taking the true RDA of 200mcg per day.

我写此之前，大约有2 / 3地球的耕地土壤是完全缺乏硒，一个重要的微量元素和矿物质的权力，不仅需要为生产的SOD ，而且还一说是一个功能强大的免疫强心针，癌症战斗机和长寿的矿产太，大部分人都几乎没有硒在他们的饮食，这是另一个重要原因，以确保您以真正的推荐的每天
