查询词典 trace

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

It is proved that every Lie derivation of nest algebra is the sum of an associative derivation and a general trace. Every Lie isomorphism between nest subalgebras of a factor von Neumann algebra is the sum of an isomorphism and a general trace or the sum of a negative anti-isomorphism and a general trace. Lie invariant subspace of linear mappings on Banach algebras is introduced, and linear maps from nest subalgebra of a factor von Neumann algebra into itself which satisfy the property that the space of derivations is their Lie invariant subspaces are characterized. Simultaneously, it is shown that such maps are Lie derivations modulo the set of scalar multiple of the identity.

得到Lie导子的特征表示，即套代数上的任何一个Lie导子都是内导子与广义迹之和；给出了Lie同构和同构及反同构之间的关系，即因子von Neumann代数中套子代数之间的任何一个Lie同构要么是同构与广义迹之和要么是负反同构与广义迹之和；引入了Banach代数上线性映射的Lie不变子空间，并给出von Neumann代数中套子代数上以导子空间为Lie不变子空间的线性映射的一个刻画，同时也表明在模去数乘恒等映射的意义下，以导子空间为Lie不变子空间的线性映射就是Lie导子。

The results revealed that there were rich trace elements in female silkworm moth, the total contents and essential macro elements of 10 familiar trace elements were 27339.30 mg/kg and 26900.00 mg/kg, respectively. The contents of 4 kinds of trace elements which are needed more in human beings were higher in silkworm moth than that in the important Chinese traditional medical insect moth, insects belonging to Meloidae. The content was also in agreement with human daily requirement.

微量元素含量的比较表明，人工栽培铁皮石斛中10种微量元素含量与铁皮枫斗大致相近，铁皮石斛组织培养物中除Cu之外的其他9种微量元素高于其他石斛材料，而铁皮石斛胶囊中微量元素含量相对较低。

By using AAS and XRF, the contents of Cr, Pb, Mn, As, Se, Hg, Cd, Zn in raw coal, bottom ash and fly ashes are measured quantitatively in a 220 t/h pulverized coal boiler. Factors affecting the distribution of trace elements are investigated, including fly ash diameter, furnace temperature, oxygen content and trace elements' characters. The coefficient of Meij is also improved to more directly show element enrichment in combustion products. Elements may be classified into three groups according to volatility features of trace elements.
