1、市场实验调查法的概念 实验调查法法的定义： 实验调查法，是指市场实验者有目的、有意识地通过改变或控制一个或几个市场影响因 素的实践活动，来观察市场现象在这些因素影响下的变动情况，认识市场现象的本质和发展 变化规律

一、市场调查 1、定义 市场调查也称市场调研，它是应用各种科学的调查方式方法，搜集、整理、分析市场资 料，对市场的状况进行反映或描述，以认识市场发展变化规律的过程

实验是一种科学的认识方法，最早是应用于自然科学领域，后来逐步应用到社会经济问 题的研究中。实验调查法是一种重要的直接调查方法，即搜集第一手资料的方法，同时也是 一种比较复杂的调查方法。在市场调查中，应用实验调查法也是认识市场现象的一种重要的 途径

市场是由千差万别的个体所组成的复杂总体，对市场总体情况进行调查，若能够做全面 的、普遍的调查，其所得的资料当然是最能反映市场总体特征的。但是在许多情况下对市场 实施普查是非常困难的，甚至是根本不可能的

观察法和访问法是市场调查中最常用的搜集资料方法，它们都是直接调查方法，即在搜 集市场资料时，市场调查者与被调查者是直接接触的。观察法和访问法各有其特点，在市场 调查中各有其适用条件

6.2 Pumping considerations Since the rate of separation depends on the oil globule size it will be appreciated that any disintegration of oil globules in the oily feed to the separator should be avoided and this factor can be seriously affected by the type and rating of the pump used. Tests were carried out by a British government research establishment some years ago on the suitability of various pumps for separator feed duties (Double vane, Triple screw and Single vane )

A. Trichopoulou and A. Naska, University of Athens 2.1 Introduction Documenting and monitoring dietary patterns are priorities in nutritional epi￾demiology, in the planning of national food and nutrition policies and in the evaluation of nutrition education strategies. Early efforts in documenting dietary patterns were focused on identifying the specific nutrients that may be respon￾sible for effects on people’s health, but recently research has expanded towards studying patterns of food intake. Food data are often derived from:

A requirement of this course is that the students experiment with a random matrix problem that is of interest to them. Often these explorations take the shape of a little bit of theory and a little bit of computational experimentation. Some of you might already have some ideas that are relevant to your current research. Regardless, we thought we’d put together some ideas for projects. Feel free to adapt them
