Multi-aim geochemistry agrology survey in deeply overcast areas serves to the evaluation of the agriculture, environment, mineral resources and study of the fundamental geology. In this paper, we discuss emphatically the restrict mechanism between the activation of mineral elements and their contents of CaCO3 and pH, and show the importance of the study of soil pH and CaCO3 for agriculture and environment protection.

深覆盖多目标地球化学调查,旨在通过土壤地球化学测量,为农业、环境、矿产资源评价及基础地质研究服务,作者重点阐述了土壤pH值、 CaCO3含量与土壤矿质元素活化之间的制约机理,论述深覆盖多目标地球化学调查要实现服务于农业、服务于生态环境保护的目标,就必须加强对土壤pH值及CaCO3含量调查研究。

Results The indoor air quality of middle - age intellectuals was bad.The CO was remarkable air pollutant.

In this paper, the bump patterns for flip-chip packages are discussed first, then an experiment is setup to study the dispensing phenomena for different bump patterns, and the CAE software is used to analyze and identify with experiment mutually. From these thorough comparisons and analytical analysis, the existence of channel could slow down the flow, the high density of bump could speed up the flow, and it could avoid the air trap by modified the bump and channel's arrangement on flip-chip package. Then flows in rectangular microchannels driven by capillary force and gravity are discussed; furthermore, the theoretical model of flow in microchannel driven by capillary force and gravity is formulated from the Navier-Stokes equations.

本文首先针对覆晶底部充填进行相关理论推导、实验与模拟,探讨不同凸块配置模型所造成的波前不平滑现象对底部充填流动的影响;即依据相关参数建立模型进行底部充填实验,同时以CAE(Computer-Aided Engineering)模流分析软体进行模拟,在完成理论探讨、实验与模拟分析之后,交叉比较理论、实验与模拟分析结果,归纳出影响底胶充填流动之因素,由结果显示在凸块密集度较高的域,凸块可以帮助流动,但是在凸块后方的沟槽域则因为凸块所提供之流量不足,所以会造成波前落后的现象,另外藉由修改凸块与沟槽配置的关系,可以有效的控制波前形状的变化情形,避免产生包风现象。
