The paper gives a brief introduction on theory and means of orebed digitaled and interrelated mining software in domestic and international. On the basis of systematic analysis and research on Jiayashan ore segment, with the mathematic-economic model software bag developed by our library, via the special software Surpac and Micrmine, on the need of the Lanping Pb-Zn mine, the mathematic-economic model of the deposit has been established in Lanping pb-zn mine Jiayashan ore segment. Correlative important technological and economic guide lines have been analyzed and studied. At last, some fruits have been achieved:(1) For the first time, the mathematic-economic model of Lanpingpb-zn mine has been established , digitated and visualed of all kinds of useful information on ore body have been realized.

本文在对矿床数字化的理论与方法及相关的国内外矿业软件综述基础上，通过对该矿床的架崖山矿段地质特征进行充分分析和研究，运用自行研制的大型"矿床数学-经济模型软件包"，以国外矿业软件Surpac和Micrmine为辅助，结合兰坪铅锌矿矿山的实际需求，建立了兰坪铅锌矿架崖山矿段矿床数学经济模型，并对相关的重要技术经济指标进行了分析与研究，最终取得了如下成果：(1)首次在兰坪铅锌矿架崖山矿段建立了矿床数学-经济模型，实现了矿体各有用信息的数字化和可视化。

In the present experiment, the tender stems of Dracaena cambodiana were used as explants to establish a two-step tissue culture and regeneration system. The effects of types and concentrations of plant hormones on the induction of callus were studied. Based on these, the reactions of callus regeneration to different mutation-induced approaches (60Co irradiation, EMS and colchicines), the regeneration ability of the treated callus as well as the characters diversities (including the appearance traits and cytological observations) of the regeneration plants were investigated.

本试验以龙血树幼嫩茎段为材料，通过对龙血树幼嫩茎段两步培养法再生的研究，建立了龙血树幼嫩茎段离体再生体系，证明了愈伤组织的发生和激素种类与浓度的关系；并在此基础上研究了愈伤组织再生对不同人工诱变方法（60Co辐射、EMS、秋水仙素）的反应、被处理愈伤组织再生能力和再生植株性状多样性、以及再生植株不同生理角度的变异性，得到了2株变异株系。

The proximal and distal nerve stumps were sutured l cm apart, in an end-to-side fashion like ＂π＂, to the epneurium windows, opened by removing the epineural sheath on the intact tibial nerve trunk with 1 mm long.

方法将大鼠右侧腓总神经在胭窝处剪除约5mm后，将断裂的腓总神经近端和远端分别就近与同侧胫神经上的外膜窗施行端侧吻合，吻合口间距约10mm；动物存活24个月后，将手术侧近端吻合口以上胫神经剪断，再将辣根过氧化物酶注入远段腓总神经干内，72h后取材并经四甲基联苯胺显色显示脊髓L3-6节段神经元和L4、L5脊神经节细胞，同时取腓总神经远段行电镜观察神经纤维再生状态。

The matrix differential equation is solved using method of steps and applying Laplace transform. Using this method and exact solution of the matrix differential equation with delayed arguments was....

On the other hand, after the reformation the unit specific energy consumption decreased 10 kilogram equal normal fuel oil per ton raw oil. In this paper, author analyse the principle and the advantages of the two stage riser fluidize catalytic cracking technology, where catalyst flow in relay and react in section, and short contact time and high c/o ratio. This paper propose a new method to calculate the catalyst circulation rate in each riser of a two stage riser fluidized catalytic crack unit and find out that the c/o ratio is lower than it should be by calculation use this method and give a suggestion to solve this problem.

本文从理论上分析两段提升管催化裂化技术的催化剂接力、分段反应、短反应时间和大剂油比特点的优越性，并对采用两段提升管技术后装置的生产状况进行核算，还提出了一种适用于两段提升管技术的计算各提升管中催化剂循环量的方法，通过计算分析出装置目前存在的第二提升管剂油比低的问题，并提出了改进建议。
