1万t水压机学习控制系统

介绍了一种实现1万t多向模锻水压机无人操作的学习控制系统．该系统由两级计算机系统组成．通过操作人员示教生产一定数量的锻件，学习控制系统在线学习，形成操作知识库，在进入批量生产时，该系统替代操作人员自动完成水压机的操作．本文着重阐述了表达操作过程特征值的提取方法、操作知识库的结构和无人操作的实现。     

Synthesis of glucoside compounds of ferrocenyl phenols and their antianemic activity

Six glucoside compounds have been synthesized by means of phase-transfer catalytic method and deacetylation from the starting material ferrocene. Their structures have been confirmed by elementary analysis, IR,¹HNMR and MS. The antianemic activities of some compounds have also been tested. Results indicate that these glucoside compounds possess the antianemic activities and therefore, the further study is well worth making.

Collaborative applications based on the internet

The basic concepts of collaborative applications and some relevant aspects about network communications are introduced. With the examples of some collaborative applications developed by us, several technical problems about collaborative applications, such as loss of data packets, unknown IP address and timedelay, are discussed in detail. And the methods of solving these problems are also provided. Supported by International Cooperation Project (Japan, Jincheng Co. Ltd) Fang Rui: born in 1975, Graduate student     

采用频域与空域结合的错误掩盖算法

提出了一种空域与频域相结合的错误掩盖算法。本算法利用损坏区域周围的纹理特性对不同的坏块区分别采用频域或空域的方法来恢复。频域方法利用离散余弦变换的一些性质，用部分ＤＣＴ系数来恢复原块；空域算法采用逐点恢复的方法。     

多效唑对幼年桃树生长发育的影响

多效唑施于土壤中，对雨花露桃的营养生长有明显的抑制作用，但能增加叶绿素含量，促进成花，改变果形指数；在蟠桃上叶面施多效唑对其营养生长和生殖生长影响不明显，但明显地改变果形指数。土壤的最佳处理浓度为０．８ｇ／ｍ＾２。     

枣快速繁殖技术研究

通过三年对枣树组织培养的研究和实践应用，结果表明，适宜的灭菌时间为７５％的乙醇５．７ｓ，０．１％升汞１０ｍｉｎ。适宜的激素配比为６－ＢＡ３４ｍｇ／Ｌ＋ＮＡＡ０．０１ｍｇ／Ｌ，适宜生根的激素为ＩＢＡ０．４－０．６ｍｇ／Ｌ。
