Pumping Systems—HPLC pumping systems deliver metered amounts of mobile phase from the solvent reservoirs to the column through high-pressure tubing and fittings. Modern systems consist of one or more computer-controlled metering pumps that can be programmed to vary the ratio of mobile phase components, as is required for gradient chromatography, or to mix isocratic mobile phases (i.e., mobile phases having a fixed ratio of solvents). However, the proportion of ingredients in premixed isocratic mobile phases can be more accurately controlled than in those delivered by most pumping systems. Operating pressures up to 5000 psi or higher, with delivery rates up to about 10 mL per minute are typical.

泵系统—HPLC 泵系统通过高压管路和设备将储液系统的流动相按设定的流量精确地输送通过柱子，最新的泵系统由一台或更多的计算机测量控制泵使得流动相组分能够按照程序变化改变比例，如有必要，可以进行梯度洗脱或混合均匀的流动相（i.e。，流动相可以是混合比例的溶液），然而，当操作压力达到或高于5000 psi，流速达到10ml/min的典型值时，预混合均匀的流动相各成分的比例就比泵控制的更精确。

Then it made denoising and edge detection for the CT image of the brain aiming at the properties and keystoned of CT image. In the process of denosing for CT images of the brain,because it has some characteristics,such as the biomedical signal is a typical non-stationary signal with a strong noise in background,it is more difficult to resolution.

在对脑部CT图像的去噪处理过程中，本文针对生物医学信号是典型的非平稳信号，具有很强的背景噪声，处理起来较困难的特点，引入了一种基于EMD方法的脑部CT图像去噪方法，它可以有效地去除噪声的干扰，充分保留信号的局部特征。

The experimental results are as follows:1、 In the Inner Mongol typical steppe community, Stipa grandis、 Koeleria cristata 、 Artemisia frigida and Kochia prostrate turn green relatively early.

初步得出以下结论： 1、在内蒙古典型草原群落中，大针茅、洽草、冷蒿和木地肤返青较早，糙隐子草返青最晚，黄囊苔草和星毛委陵菜的生长开始得最早。

Natural changes result in lenticular sclerosis, whichtypically does not cause significant vision loss.

晶状体的物质改变导致其硬化，此典型上是不会造成显着地视力减退。

In order to get more scientific information on the clsssification and use of two kinds of typical paddy soils in Jiangsu Province, we studied four soil profiles from two different regions:the Xiashu loessial uplands and the low lands to the east of Hongze Lake.

为给江苏省两种典型水稻土的分类和利用提供更多的科学依据，我们对两种不同起源土壤的四个剖面进行了研究。一类为下蜀黄土丘陵谷地，另一类为洪泽湖以东的低温地。

A typical longtail boat in the area, these can fit up to a dozen

In the first part, the thesis mainly checks the concept of urban and rural dual structure, manages to give it a philosophic, definition and then lists various conducts of the contradiction. It also analyzes the subjective and objective reasons that cause the Chinese urban and rural contradiction, and dissect the contradiction抯 feature, history, current situation and influence. This part means to explain that China is a prototypic developing country with Chinese characteristic urban and rural dual structure co!~tradiction. The incisive contradiction exists mainly in seriously backward countryside. In the fields of economy, politics, culture etc, it badly affects and restrains our economy and society抯 sustained, rapid and coordinated development manifoldly and omnibearingly.

第一部分从考察城乡二元结构的概念开始，给予城乡二元结构以哲学定义，然后列举了我国城乡矛盾的种种表现，分析了我国城乡矛盾形成的主客观原因，进而剖析了我国城乡矛盾的特征、历史与现状及影响，旨在说明我国是典型的具有中国特色的城乡二元结构矛盾的发展中国家，城乡矛盾极其尖锐，主要表现为农村元严重落后，在经济、政治、文化等方面，多层次全方位地严重影响和制约着我国经济与社会的持续、快速、协调发展。

Several new typical fuzzy matrices are given and studied in this paper.

本文给出了几种新的典型阵并对它们进行了较为深入地研究。

This is due to the dry friction damping is merely limited to shroud interface and is a standard local nonlinear problem, when directly solving it, most operations will be used meaninglessly to regenerate its linear elements except for modifications of some elements of stiffiness matrix and damping matrix.

这是由于干摩擦阻尼只局限于凸肩接触面，是典型的局部非线性问题。直接迭代求解时，除了只需对系统刚度矩阵、阻尼矩阵的个别元素进行修正外，有相当一部分运算毫无意义地用于线性元素的重新生成上。

The CBC here shows a markedly increased MCV, typical for megaloblastic anemia.

全血细胞计数显示MCV明显地升高，是典型的巨幼细胞贫血的表现。
