查询词典 survey

This paper is a generalization and summation of some new progress in marine chemistry in the recent decade. The principal contents consist of seven parts:1. Oceanological survey. The oceanological survey covered the China Seas, the Pacific Ocean and the Antarctic Ocean.2. Interaction of minor elements and suspended matter in seawater and the theory of in-terfacial stepwise ion/coordination partical exchange.3. Effect of organic matters on the liquid-solid interfacial exchange and the rule of left-righ...

Methods The family background,individual health habit,types of facial skin and facial dermatitis of 1 211 local university medical college freshmen were survey by using questionnaires survey.The vermiform mite samples were collected with cellophane tape.

方法对莆田学院医学院一年级1211名大学生的家庭背景、个人卫生习惯、皮肤类型及脸部疾病等相关因素作问卷调查，同时采用透明胶带单粘过夜法进行蠕形螨检查。

This instrument generated the sine wave signal which frequency could change in three situations. The sine wave signal inputted to the buffer amplifier, then divided into two groups, a group connected with oscilloscope to survey the peak-to-peak value of fundamental wave, another group connected with wave trap to filter out the fundamental wave, then the oscilloscope was used to survey the various sub-harmonics amplitude of the output.

该仪器是通过设计可变三种频率的正弦波信号发生器产生的正弦波信号，其输出信号经过缓冲放大器，输入放大器后分为两路，一路接入示波器，测量基波幅值；另一路接入陷波器将基波滤去，再用示波器测量其输出各次谐波幅值。

Wolff and her colleagues analyzed data from the 1999 National Long-Term Care Survey and its Informal Caregivers Survey.

Methods: Between April and November, 2004, we carried out a cross-sectional study that administerd a self-assessed health questionnaire survey to the parents of 1,117 children from 14 elementary and junior high schools with high tension power lines hovering over the campuses. The control group was consisted of 2,204 children from 18 control schools. Multivariate multinominal logistic regression model was used to calculate the age and socioeconomic indicators adjusted odds ratios and the corresponding confidence intervals of clinical visits and health conditions within a one- month period prior to questionnaire survey in relation to the putatively hazardous exposure to magnetic fields.

本研究利用横断性研究设计，在2004年4月至11月期间，针对台北县市14所校园上空有高压输电线跨越之国民中小学学童1，117名以及18所校园上空无高压输电线跨越之国民中小学学童2，204名的家长进行过去一个月以来，对学童健康情形之自我评量问卷；并利用多变量多名义逻辑斯迥归模式调整年龄与社经指标后，计算胜算比及其相对应之信赖区间，用以估计暴露组学童过去一个月内生病与就医症状的相对危险性。

The authors introduce the agrogeological environmental survey and status quo of the certification of agricultural products in China, and on that basis they demonstrate that the results of agrogeological environmental survey can be used in the certification of pollution-free agricultural products, green food and organic food, especially in the certification of origin of organic food.
