The original defined adakitesare sodium igneous rocks, they are tonalite, trondhjemite or (plagioclase-rich) granodiorite in whole-rock chemistry; however, the K-rich "C-type" adakite defined by Chinese scholars are potassic igneous rocks, they are granite, quartz monzonite and (alkali feldspar-rich) granodiorite, etc.

In addition,during the investigation of cadmium different levels distribution in Typha angustifolia Linn,we find that:l as far as the accumulate ability of different organ in Typha angustifolia Linn are concerned,root sheath leaf.

此外对狭叶香蒲体内镉的化学形态分析表明根和叶中均以氯化钠提取态最高，但在根中以去离子水和乙醇提取态存在的镉含量总和大于氯化钠提取态，表明镉在根与叶的化学存在形态有所不同。

Sequential leaching experiments indicate fluorine in carbonate rock, phosphorite and Mo-Ni ore layer occurs principally in dissolvable forms: water-soluble, associated with carbonate or phosphorite, so fluorine in which rocks have high chemical mobility at surface conditions. Fluorine in siliceous rock, black shale and carbonaceous slate mainly occurs in undissolvable forms, which are inert at surface conditions.

氟在碳酸盐岩、磷块岩、钼、镍等多元素富集层及部分硅质岩中主要以水溶态、碳酸盐结合态等易溶形式存在，其在自然条件下的化学活动性强；而氟在碳质板岩、黑色页岩及大部分硅质岩中主要存在于难溶矿物中，其化学活动性较弱。

Two kinds of silicon samples with distinct surface treatment, i. e., one surface was chemically etched and the other was unetched, were used to investigate the characteristics of leakage current and surface flashover of semiconductor under impulse voltage in vacuum. The experimental results showed that the surface conditions of samples affected these characteristics greatly. Before flashover, the Ohmic current was observed for unetched samples and the space charge limited current for etched samples, respectively. Meanwhile both samples showed quite different flashover tracks, and the surface-etched samples displayed a much higher onset voltage of flashover.

对采用和未采用表面化学腐蚀处理的半导体硅在冲击电压下的实验表明（参见 Zhang et al ， Applied Physics Letters， 2002），试品的表面状况对其泄漏电流和沿面闪络特性有着很大的影响：在沿面闪络之前，未经处理试品的泄漏电流表现为 Ohm 性电流，而表面处理过的试品表现为空间电荷限制电流特性；同时两类试品表面的闪络通道也表现出不同的特征，而采用表面化学腐蚀处理可以明显提高其沿面闪络电压。

And NMF has never been applied to resolve mixed chemical signal. It must be modified according to the characteristics of chemical signals, such as smoothness of spectra, unimodality of chromatograms, sparseness of mass spectra, etc..

作者根据化学波谱的基本特征（化学波谱的平滑性、色谱的单峰性以及质谱的稀疏性）对NMF算法进行了改进，缩小了其多解范围。
