As there are only six parents in the diallel crossing. and one cross combination for genetic effect analyzing, and the datum from the number of regenerating didn't submit to the normal distribution formula even when they were transferred, there may be some aberrancy in the result of this character. Therefore, more experiments and larger samples are needful further to conform, improve or correct this research results later.
7本研究双列分析的亲本仅为6个,世代的基因效应分析也仅只有1个组合,可能导致统计分析结果偏颇,还由于性状胚性愈伤组织绿苗再生数资料经转换后仍不能遵从正态分布,也会使得该性状的分析结果可能有偏差,今后需要用更多的试验和抽取更大的样本进行分析研究,进一步证实、完善或纠正本试验结果。

In order to prove the reliability, test studies have been primarily carried out in the indoor soil bin. The data of the vehicle driving state parameters under the same or different terrain are analyzed. The process curves are compared by different control schemes. The theoretical model of the optimum driving state is reliable and fuzzy control scheme is feasible. The disturbances and unknown factors of control system are analyzed. Test results prove that the half-tracked air-cushion vehicle can drive steadily under control of the computer. At the same time the sensors used to measure soil mechanics characteristics on line need to be developed. And it is the important problem to be solved in the future study. The necessary regulation and correction are put up. So the studies in this paper provide some instruction for the further research work.

Main contributions and achievements are as follows:A general non-equilibrium rigorous model for RDP is developed in this thesis. Based on the pseudo-homogenous assumption, two main factors reaction and separation are de-coupled, and an RDP model with the same format as that for a traditional distillation process is established. To solve the model with a large number of algebraic equations, modified M-K equations with tri-diagonal matrix form are developed based on the improved Separation Efficiency Functions, which greatly increases the iteration efficiency. This thesis also develops a general reactive distillation dynamic model. Through splitting of the differential variables based on SEFS, large-scaled differential algebraic equations can be solved with the improved Gear's algorithm which makes the dynamic model suitable for the on-line application. A simulation platform for the control loop design and evaluation of RDP by introducing control system equations into the dynamic model is also developed.A lactic acid purification pilot-scale RDP is investigated.

Berthelot, the great French founder of modern synthetic chemistry, once stated in a letter to a close friend that the final experiments which led to his most wonderful discoveries had never been the result of carefully followed and reasoned trains of thought, but that, on the contrary,"they came of themselves, so to speak, from the clear sky."
