  weak feature
One well-defined OH Raman band at 3651?± 1?cm-1 and one weak feature near 3700?±?5?cm-1 are recognized for the hydrous γ-phase of Mg2SiO4.
      
Another weak feature is assigned to nitrogen clusters in the α-phase.
      
For this, one introduces the weak feature size (wfs) that extends for nonsmooth objects
      
A weak feature often persists in the umbra after the flash.
      
Frequently this structure consists of two distinct components: a central, strong, rather narrow line, and an often displaced, weak feature of undefined profile appearing as 'fuzz'.

主成分变换对于区分多光谱遥感数据中岩性信息有一定效果。利用主成分变换的2 个因子散点图分类提取多光谱遥感数据中较弱岩性信息时,发现这些弱信息并不是出现在散点图重合部分的重心位置,说明多光谱原始遥感数据之间除了存在着起支配作用的主特征值外,还存在反应较弱信息的特征因子。而主成分变换只表示了特征空间系列变换的一种结果,为了提取和显示多因子变化空间中出现的较弱特征信息,开发了多因子逐步正交变换算法软件,在峪耳崖金矿带应用时取得了较好的效果。研究中还采取了掩膜技术排除水体和河道的干扰信息。该方法已用在华北地台北缘其它地区的找矿。

The purpose of this paper is to find the distribution patterns of some typical diatoms from the surface sediments in the South China Sea(SCS) and to discuss the relationship between the distributions of surface sedi-ment diatoms and the ocean environments, especially the current pattern of SCS. The result shows that the subtropical planktonic species Thalassionema nitzshioides dominates the surface sediment diatom assemblages throughout SCS with relatively small changes, which indicates that the water-mass exchanges among SCS, the Pacific and Indian oceans are relatively small. The warm water planktonic species Nitzshia marina, Azpeitia neocrenulata, Azpeitia afriacana and Rhizosolenia bergonii can be used as an indicator of the intrusion of Kuroshio Current and Indian ocean warm water in the paleoenvironment reconstruction. Whereas Cyclotella striata, Cyclotella stylorum, Diploneis bombus, Traychneis aspera and Tabularia tabulata can be used to identify the influence of the coastal currents in SCS.

本文通过对南海表层沉积物样品的硅藻分析,试图揭示南海某些表层沉积硅藻的分布规律,以便为南海古海洋学研究提供科学依据。研究发现,Thalassionema nitzshioides 为南海地区表层沉积硅藻的优势种,且其百分含量无明显的区域差异,体现了南海与周围海洋水体交换相对较弱的特征。除此之外,南海表层沉积硅藻的分布主要受到海洋环流的影响,表现在黑潮暖流、印度洋暖水的入侵以及沿岸流对南海表层沉积硅藻分布的影响。其中,Nitzshia marina, Azpeitia neocrenulata, Azpeitia africana, Rhizosolenia bergonii 等暖水硅藻可作为黑潮暖流及印度洋暖水入侵南海强度的指标种。而Cyclotella stylorum, Cyclotella striata, Diploneis bombus, Traychneis as pera, Tabularia tabulata 等则可看作判断沿岸流对南海水体影响强度的标志种。

In order to quantitatively describe the liquid identification function of the Opto-electronic Liquid Drop Fingerprint (OLDF), a method for extracting features of fingerprint based on waveform analysis is proposed. The peak and valley positions of fingerprint are determined by using neighborhood comparison method or extreme detection based on maximum and minimum. The parameters of capacitance signal and fiber signal for characterizing main peak, secondary peak and valley, curve length and curve area of fingerprint, are calculated, respectively. Experiments demonstrate that curve area is the most effective identification parameter and the relative identification ratio of different kinds of liquid is 7.45%. The relative identification ratio of different brands of water, drink, wine, vinegar and soy are 1.96%, 7.64%, 14.39%, 0.07% and 3.65%, respectively. The secondary peak of fingerprint has relative weak feature with relative identification ratio only 0.07%.

为了定量地描述“光电液滴指纹图”鉴别液体的功能,提出一种波形分析法来提取指纹图的特征参数。采用“邻域比较法”或“基于最大值和最小值的极值检测法”确定指纹图的峰谷位置,分别计算表征主峰、次峰和波谷的电容信号和光纤信号的参数,以及指纹图的曲线长度和曲线面积。实验证明,“曲线面积”是最有效的识别参数,不同种类液体的相对分辨率为7.45%;同一种类不同品牌的水、饮料、酒、醋和酱油的相对分辨率分别为1.96%,7.64%,14.39%,0.07%和3.65%。指纹图的“次峰”是相对较弱的特征,相对分辨率仅为0.07%。
