In this paper, comparative studies on the memory responses of white mice to earthquake premonitory thunders with a main peak frequency of 200 Hz and to pink noise are given. The results show that white mice not only can obviously form memory response to geo-sound signals but the sensibility of trained mice to this kind of geo-sound signals is markedly imporv-cd.1. In geo-sound group (Gs. G.) and noise group (N. G.), the time-intensity curve (TIC) of pass-door reactions both approximate to an exponential altenuation,...

In this paper, comparative studies on the memory responses of white mice to earthquake premonitory thunders with a main peak frequency of 200 Hz and to pink noise are given. The results show that white mice not only can obviously form memory response to geo-sound signals but the sensibility of trained mice to this kind of geo-sound signals is markedly imporv-cd.1. In geo-sound group (Gs. G.) and noise group (N. G.), the time-intensity curve (TIC) of pass-door reactions both approximate to an exponential altenuation, and the peak intensity within the range of periods of 1-5s (SPL 10 dB) is 0.71 and 0.40, respectively. In control observations (Con.), the TIC approximates to a normal distribution of stochastic events, and rhe reaction intensity within the periods of 1-5s is only 0.13, its peak intensity within the range of periods of 11-15s is 0.32.2. In the Gs. G., the latency of pass-door responses to the geo-sound signal at lOdB is on an average 245±0.5s, that is, it is on an average 0.86s shorter than that the N. G.; and to the geo-sound signal at 10-30 dB is shorter than the N. G. by about 2s.3. In the Gs. G., the collective effects of pass-door reaction are obvoiusly improved and the ratio of pass-door rection by the groups of three and four mice is 1.6 and 2.9 times of the Con., respectively.4. In test animals of the Gs. G., the TIC responding to a tone of 250 Hz still approximates to response to geo-sound signal, but the response to the pink noise obviously loses the original reaction properties.

本文比较研究了小白鼠对主峰频率200Hz的前兆性轰隆声和对粉红噪声的记忆反应。结果表明,小白鼠不仅能对这种地声信号产生明显的记忆反应,而且受训鼠对这种地声信号敏感性显著增高。 1.地声组(Gs.G.)和噪声组(N.G.)穿门反应的时间-强度曲线(TIC)都近似指数衰减。在1—5s內(SPL 10dB)的峰值强度分别为0.71和0.40。对照观察(Con.)的TIC近似随机事件的正态分布,1—5s內的反应强度仅为0.13,11—15s內的峰值强度为0.32。 2.地声组对10dB的地声信号穿门反应的潜伏期为2.45±0.5s,即比噪声组平均短0.86s;对10—30dB的地声信号穿门反应的潜伏期比噪声组约短2s。 3.地声组穿门反应的群体效应明显增高。以3只鼠和4只鼠的群体穿门反应的比率分別为Con.的1.6倍和2.9倍。 4.地声组的受试动物对250Hz纯音反应的TIC仍接近于对地声信号的反应,而对粉红噪声的反应明显地失去原来的反应特性。

In an attempt to treat binary tract stricture caused by cancerous bile duct, the equipment Ni-Ti memory-alloy form was ed to expansile and support the bile duct. Since May 1993 to October 1996,Ni-Ti memory-alloy froms were used in 13 pa- tients. Results: 11 patients received the equipment during operation. The operation was simple, all operations met with suc- cess and had no complication.The jaundice in 11 cases gradually disappeared within 7 days. The short-term curative effect rate was 80%.

In an attempt to treat binary tract stricture caused by cancerous bile duct, the equipment Ni-Ti memory-alloy form was ed to expansile and support the bile duct. Since May 1993 to October 1996,Ni-Ti memory-alloy froms were used in 13 pa- tients. Results: 11 patients received the equipment during operation. The operation was simple, all operations met with suc- cess and had no complication.The jaundice in 11 cases gradually disappeared within 7 days. The short-term curative effect rate was 80%. All the cases were followed after operation. The long-term curative effect rate was 90%. The usefulness of operations with Ni-Ti form memory-alloy . stands was discussed in detail.

In the midship section optimum design, the design variables include continuous variables and discrete ones. How to solve the mixed variables optimum problems has drawn great attention from the ship building field. In this paper, a new optimum technology, simulated annealing (SA), which can solve the mixed variables optimum problem was introduced. The outstanding advantage of SA contrast to other optimum methods is that it can find the global optimum solution. In addition, SA does not depend on the initial solution, so it can greatly reduce the incipient work on choosing a proper initial solution. SA also has several refined forms (memory, tempering, heat annealing etc.) which can be used intelligently according to the different requirement of the optimum problem. A refined form of SA (tempering annealing with memory function) was applied in the structural optimum design of the midship section of a real ship in this paper and the ideal and reasonable result was obtained, which shows that SA is feasible and effective in the optimum design of the midship section and can be used in other engineering optimum design field.
