Thirdly, a new type base isolation system, i. e., slide-limited friction base isolation system is presented in this paper. Based on this system, harmonic and subharmonic periodic response of S-LF subjected to harmonic motion is investigated by using Floquet theory. Dynamic response of sliding structure subjected to earthquake ground motion is calculated with a precise high order direct integration method, and the numerical results are presented in terms of maximum acceleration response spectra of supcrstructure and maximum sliding displacement response spectrum. By comparison with isolating effects of pure-friction base isolation system and resilient-friction base isolation system , it shows that the isolating characteristic of S-LF is superior to P-F and R-FBI. Through analyzing an engineering example, it is observed that the maximum inter-storey shear force and absolute acceleration of sliding structure to earthquake ground motion are very different from those of traditional structures.

提出了一种新型基础隔震模型，即带限位装置的摩擦隔震体系；基于此隔震模型，利用Floquet理论研究地面谐运动下S-LF结构的运动特性；并利用高精度的精细时程积分法，通过对地震作用下S-LF动力响应的计算，绘制了上部结构最大加速度反应谱和基底最大滑移量反应谱，并研究了各种结构参数对隔震的影响；通过与恢复力摩擦隔震系统和纯摩擦力滑移隔震系统的比较表明，S-LF的隔震性能优于P-F和R-FBI；对计算实例的分析发现，地震作用下S-LF结构的层间最大剪力和最大绝对加速度反应分布较一般传统结构有很大区别。

By the cooling curve and the temperature field, it can he known that, the solidification time of ribbon is 1.0×10^(-4)s, the even solidification rate of ribbon with 60 μm thickness is about 10^6K/s, and the temperature of cooling process does not obviously go back by the release of solidification latent heat. The solidification rate of ribbon is at 0.010-0.394 m/s, and it changes from high to low with the prolonged solidification time.

He s sure he s going to go through with the divorce, is excruciatingly lonely, and in extreme pain, so, like most men, he s going to make the pain go away as fast as he can, by finding the love of another woman.

他s肯定他s会继续透过与离婚，却并不如人们所愿寂寞，和在极端的疼痛，因此，最喜欢的男子，他s去，使疼痛消失一样快，他可以找到爱情的另一名女子。

Can accelerate the bone marrow cell from G1 phase into S phase when we measure it's Cell cycle, it make S phase rate was increased .thus it promoted DNA synthesize and repaired. Mice irradiated at dose of 5.5 Gy gamma-irradiation showed timed-related decreases and restores in peripheral blood picture at day 1 through day 21, the counts of WBC of these group had taken drug has various degree to increase than irradiation control group in day 1. Grugs failed to protected the peripheral blood cell at lowest point, but seems promote their rescovery.9803 treated group was distinct. At 7days after mice were radiated in 3.5 Gy. we observed drug can Significantly hold back the decreased number of hematopoietic progenitors colony forming radiation induced. These findings indicated 9803 have a certain radioprotective activity against gammer irradiation in mice.

给药组的 CFU-S 数量较照射对照组明显增加，3.5Gy 照后第七天观察给药9803组对小鼠骨髓造血组细胞集落生成能力的影响，给药组的造血祖细胞集落的形成能力强于照射对照组，并且9803组明显优于523组。5.5Gy 照射引起的小鼠的外周血细胞数量的降低以 WBC 发生最早，照后24小时给药组的 WBC 数量均比照射对照组有不同程度的升高，以9803各给药组最为明显，药物未能使照射引起的外周血细胞最低值升高，而有降低的趋势，但给药对照射后期外周血象的总体恢复有较好的促进作用。7.5Gy 照射后第七天测定小鼠骨髓细胞周期的测定中发现9803具有促进骨髓细胞由 G1期进入 S 期的效应，致使 G0/G1期细胞显著减少， S 期细胞比率显著增加，这利于促进 DNA 合成修复，即促进骨髓细胞增殖，骨髓细胞 DNA 含量给药组显著高于照射对照组。

For example,the graph in Fig.3-5 is Hamiltonian（a possible path being P→Q→R→S→T→P）but is not quite Eulerian,since any path which includes every dege exactly once（e. g.P→Q→T→P→S→R→Q→S→T）must end up at a vertex different from the initial vertex.

例如，图3-5所示是一个哈密尔顿图（存在一条路P→Q→R→S→T→P）但不是一个欧拉图，这是因为图中任何包含所有边一次且仅一次的路（如P→Q→T→P→ S→R→Q→S→T）都不能回到原出发顶点。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
