为研究行走弹性对工程车辆行走换挡过程的影响,建立了考虑驱动轮轮胎变形引起的车辆行走弹性影响的整车行走动力学模型,该模型适用于换挡过程分析。计算与分析了典型装载机动力换挡过程,将考虑或不考虑行走弹性时计算得到的整车加速度和瞬时冲击度的变化过程分别进行了对比,利用实车试验对单一换挡过程进行了验证;并将考虑行走弹性时升挡过程中变速箱输入输出转速变化过程、离合器滑摩功率特性的计算结果与不考虑行走弹性时换挡过程的计算结果进行了对比。研究结果表明:与不考虑行走弹性的情况相比,行走弹性变形使得换挡过程中整车加速度的变化更加平缓;换入挡离合器有两次滑摩过程,冲击度更小,换挡时间更长;离合器接合时的冲击度与其接入时间有关;滑摩功更小。

脉宽调制以其高效、灵活、抗干扰等优势,成为电液比例阀的标准驱动方式。同时,通过给比例电磁铁施加颤振信号可改善阀心的动态性能。针对脉宽调制驱动中的频率和占空比两个控制参数,导出了低频时的寄生颤振计算式,结果表明其振幅和频率不能独立调节。高频时,通过改变占空比的方式可实现幅度和频率均可调的独立颤振。根据感性负载的电流特性,分别导出正弦波和三角波包络线的独立颤振计算式,数值仿真与试验结果相吻合。该算法特别适合于数字信号处理与控制系统。

Objective： The aim of the study was to investigate the mechanism of gemcitabine （GEM） combination with radiation on the high metastasis human ovarian cancer cell line （HO-8910PM）. Methods： Human ovarian cancer cell line HO- 8910PM was treated with different concentrations of gemcitabine for 24 h, then the cells were counted. In the study of GEM combination with radiation, an efficiency of colony formation was observed; the cell cycle and apoptosis were analyzed by flow cytometry; the experiment of depend on the time and its radio sensitivity were observed by using mitotic index with the cells for each 24, 48, 72 and 96 h after experiment. Results： It suggested that the GEM had an inhibition effect on the human ovarian cancer cell line. The alive cell numbers were decreased by following a height of GEM concentration. When GEM in combina- tion with a radiation, the suppression was significantly increased than that of single GEM therapy. The efficiency of colony formation was significantly lower, under this condition the cell could be arrested at G0-G1 phase and could be decreased to enter into the S phase; the apoptosis percentage could be significantly increased; especially, under the 4 Gy and 6 Gy doses the cell apoptosis was more obvious. GEM combination with radiation had depended on the time to the cells; mitotic index of the calls in combination group was observed significantly lower than that of single GEM therapy or single radiation, and this showed that it had an effect of radiosensitivity. Conclusion： The GEM has a significant growth inhibition on the human ovarian cancer cells, GEM combination with radiation could induce HO-8910PM cell occurred arrested and apoptosis. It has depended on the time and has a radiosensitivity effect. The result shows that it is a better method to treat the human ovarian cancer by using radiotherapy combined with gemcitabine.

Objective： Investigation of the relationship between P-glycoprotein （P-gp） and adhesion molecule CD44 as well as their clinical significance in gastric carcinoma. Methods： To examine the expressed level of P-gp and CD44 in 98 cases with gastric carcinoma by flow eytometry and evaluate their relationships with elinieopathologieal factors. Results： Among the 98 gastric carcinomas, 40 cases （40.8%） were P-gp negative （positive cells 〈25%）; 14 cases （14.2%） were 25%-40% expression of P-gp positive cells; 17 cases （17.3%） were 41%-60% expression of P-gp positive cells; 27 cases （27.5%） were the high expression （positive cells 〉60%） of P-gp in all patients with gastric carcinoma. When the tumor sizes were more than 6 cm, the P-gp positive of CD44 showed a significant difference （P〈0.05） in 35 cases with P-gp positive, compared with it in 24 cases with P-gp negative. When the tumors were in low-moderate differentiated gastric carcinoma, the expression of CD44 showed a significant difference （P〈0.05） in 44 cases with P-gp positive, as compared with it in 30 cases with P-gp negative. When the patients were in clinical Ⅲ-Ⅳ stage, the expression of CD44 showed a significant difference （P〈0.05） in 42 cases with P-gp positive, as compared with it in 30 cases with P-gp negative. When the patients with lymph node metastasis, their CD44 expression showed a significant difference （P〈0.05） in 46 cases with P-gp positive, compared with it in 32 cases with P-gp negative. When the tumors P-gp expressed positive, their CD44 expression will be increase. Conclusion： When the CD44 and P-gp both have the positive high expression, it will be significantly associated with the gastric carcinoma progression and metastasis, so both were a positive expression in gastric carcinoma, it might suggest a poor and unfavorable prognosis result.
