It becomes a information exchange site,the exploration project,work area,research production,seismic datum,explainer datum,well datum can be organized into one system,which can share the research production in the exploration project;Through the datum expression of well decision,we can achieve the browsing of work area basemap,the seismic section"s remote display,the well position report"s display,the visual information of well"s wall.The system can lead to a right direction for those expert"s exploration decision .The system runs through all the process of well positon"s decision,deployment and management,which makes the exploration work becoming integrated.Now we can manage the well positon"s decision with computer,which improves work efficiency,condense whole exploration circle.

油田井位部署辅助决策系统以项目数据库的方式将分散在多个研究单位或个人手中的各类图档资料信息集中分类地保存起来，通过该系统使勘探项目、工区、研究成果、地震数据体、解释数据、井数据等有机地组织在一起，使勘探研究成果在勘探项目组内进行了充分共享；基于项目库，系统实现了井位部署决策所需的：工区底图浏览、地震剖面远程显示、井筒信息可视化，为论证专家提供了论证现场所需数据的展示；采用井位聚类分析和模糊数学综合评判决策方法，为井位论证决策提供了基本模型；利用井位部署流程子系统贯穿了井位论证、部署、管理业务的全过程中，使勘探业务有机的整合为一体，实现了井位论证工作的计算机管理。

In the process of urbanization , more and more people gather in cities and the suburbs of cities.

Continuous ethanol fermentations with and without recycling of distillage were carried out in two suspended-bed bioreactors,respectively,using two-stage enzymatic hydrolyte of corn powder as medium.

在2个单级悬浮床生物反应器中，以双酶法制备的玉米粉糖化液为底物，进行了废液循环条件下自絮凝颗粒酵母乙醇连续发酵与清液发酵对比实验。对于废液循环实验，每隔5d将收集到的发酵液集中精馏处理，得到的废糟液直接用于玉米粉调浆。

Mainly in a method of the lattice vector quantifying coding and decoding, a new basic code book is selected out and directly or indirectly comprises all points whose value is less than or equal to 3 of any dimension in a RE point set, and points on a fourth grade hypersphere in the basic code book are all odd points so that part of nearest adjoint point values can be comprised in the basic code book only via corresponding odd number processing.

一种格矢量量化编解码的实现方法及装置，其主要是在格矢量量化编码方案中，选定新的基础码本，在该基础码本中直接或间接地包含了RE 8 点集中任意维的数值小于等于3的所有点，且该基础码本中的第4级超球面上的点全部为奇数点，以使得部分的最近邻点数值仅经过相应的奇数化处理便可以包含于基础码本中。

We show the effects of tangential motional modes on velocity jumped rules due to collision and inapplicability of Newton's coefficients of restitution to multi-body collisions by using parametric impact models to solve the collisions of Kane's example.
