Methods A lamellar flap was produced in the rabbit cornea with a microkeratome. The flap interface in whole corneas and corneal beds were soaked in the rAAV –EGFP solution for 10 min, BSS solution was applied in the control group. The corneas were harvested at day 1, 3, 14, and 21 after application for the structure analysis of cornea by HE staining. Expression of the transferred gene was monitored by fluorescence stereoscope and laser confocal microscope. Results After 3d of infection with rAAV-EGFP ,slight fluorescence was detected in rabbit cornea by fluorescence stereoscope .

This paper is mainly the dynamic input-output model that the time lag is one, which is base on the above models. After studying, we consider stochastic factor step by step in it, namely when consumption coefficient matrix is stochastic (when investment matrix is stochastic, it is almost same. So we dont research it), and they are both stochastic, then we research the stable increase solution. We utilize the means of the modern stochastic analysis and Markov process, that the stochastic dynamic input-output model don not exist the stable solution is proved. Namely, economic system must is adjusted constantly. The probability that the collapse time of the economic system is o is one.

本文对在上述基础上构造的一类时滞为1的动态投入产出模型，进行了深入研究，将随机因素逐步考虑进去，即对投入产出消耗系数矩阵为随机的情况(投资系数矩阵为随机的情况与投入产出消耗系数矩阵为随机的情况大致相同，这里就不再证明)，以及二者同时为随机矩阵时所得到的动态投入产出模型的稳定增长解问题，利用现代概率分析及马氏过程的工具，证明了不存在随机动态投入产出模型的稳定增长解；即投入产出模型反映的经济系统必须经常进行调整，其崩溃时间为无穷大的概率为零。

Both too high and too low nutrient solution concentration could effect the growth and development of potato by aeroponic cultivation.For example,when nutrient solution concentration was 1500μs/cm or 3000μs/cm,content of photosynthetic pigments in leaves was reduced, the number of stolon were increased.

过高或过低的营养液浓度都会对马铃薯植株的生长发育造成影响，当EC值为1500μs/cm或3000μs/cm时，植株光合色素含量降低，匍匐茎形成数量少，而EC值在2000~2500μs/cm时植株生长良好，产量较高。5。

After pretreatment with TFP, although the conductance of cultivate solution of strawberry seedling under NaCl stress was not increased, growth was inhibited obviously by TFP, while the leaf relative electric conductivity in strawberry increased, leaf holding ability was reduced. The inhibiting response increased with the concentration of TFP increasing. On the contrary, conductance in cultivate solution was increased by Ca(NC?3)2 treatment, but the leaf relative electric condu

用Ca(NO_3)_2和TFP培养处理NaCl胁迫的草莓幼苗，发现TFP培养处理虽然不增加培养液的电导值，但明显抑制盐胁迫草莓幼苗的生长，增加了叶片膜透性，降低了叶片保水力，抑制作用随TFP浓度的增加而增大；而Ca(NO_3)_2处理虽然增加了培养液的电导值，但降低了幼苗叶片膜透性，提高了叶片保水力，因而减轻了NaCl

To be the heart of the dissertation, the fundamental coupling equations of multi-conductor system with both parallel and cross conductors existed are drawn by using secondary field theory. In addition to the strict solution, a kind of approximate solution, namely, equivalent transmission line equation is presented.
