查询词典 zinc

The results show that the growth rate of tetrapod ZnO is controlled by spiral growth and its crystallization is via VLS model. The condensation of tiny zinc droplets in zinc vapor is the key factor of the formation of tetrapod ZnO. The growth steps are formed on the terminated faces as zinc diffuses outwards and the elongation of whiskers continues until zinc inside the droplets is depleted. VS crystallization, which has little effect on the elongation growth, takes place on side faces of the whiskers and consequently makes the whiskers radius increase.

结果表明： T-ZnO晶须的结晶作用是气-液-固方式，晶须生长受螺旋生长机理控制；锌蒸气中产生凝聚生长的锌液滴是制备T-ZnO晶须的关键，锌从液滴内向外扩散在晶须的端面产生生长台阶，随着液滴内的原子向外不断扩散，针体部分就不断地伸长生长，当液滴内的原子全部消耗尽时，晶须便不再发生轴向生长；气-固方式的作用主要是促进晶须棱面生长而使晶须变粗，对轴向生长几乎没有影响。

The pollution of As results from the copper deposits, the lead-zinc deposits and limonite, and from their exploitation; the pollution of Cd is related to lead-zinc deposits, the exploitation, and agricultural irrigation with waste water; the pollution of Pb and Zn are mostly ascribed to the lead-zinc deposits and related exploitation.

As元素污染的主要原因是铜矿、铅锌矿褐铁矿矿床及其开发；Cd元素的污染与铅锌矿床及其开发，以及农业污灌有关；Pb、Zn元素的污染与铅锌矿床及其开发密不可分。

The contents of organic matter, total nitrogen, phosphorus, iron, manganese, copper, zinc can be increased, and the contents of hydrolizable nitrogen and their forms , Fe-P, Al-P, Ca〓-P, all organic P forms, exchangeable and organic iron, manganese, copper, zinc are increased obviously in long-term application organic manure soil. Not only the contents of soil readily oxidizable carbon, humic acid, fuluic acid, and HA/FA value are increased and Kos value decreased but also the available nitrogen, phosphorus, iron, manganese, copper, zinc are kept more high level in the organic manure soils. Long-term mulching straw has similar role with organic manure for soil nutrient except for decreasing total phosphorus, available P, N and Ca〓-P, but its fertilizer efficiency is not better than organic manure.
