活血止痛汤联合脂肪填充对大鼠胫骨骨骺损伤的影响

第37届中国控制会议

作者： Lv Yongshen Yang Xuerong Yang yajun pan Shengdong Space Engineering University

According to the problem of UGVs’ formation control in the process of motion, a formation control method of UGVs based on artificial potential field is proposed, established on the collision avoidance, aggregation and speed matching rules of UGVs. First establish the UGVs’ kinetic model in accordance to the motion rules, then design the formation control algorithm based on artificial potential field function, which is used to control the formation during the movement of UGVs. Finally, the results of simulation and physical experiment verify the effectiveness of formation control method, which is also suitable for the formation control of large-scale UGVs.

目的:探讨活血止痛汤联合脂肪填充对大鼠胫骨远端Ⅲ型和Ⅳ型骨骺损伤的作用。方法:36只大鼠随机分为对照组、模型组、脂肪组和脂肪中药组,采用阿利新蓝、免疫荧光染色观察损伤模型的建立及骨骺损伤愈合过程、骨桥形成过程及血管内皮生长因子(VEGF)、骨形态发生蛋白2(BMP2)和白细胞介素1β(IL-1β)的表达情况。结果:阿利新蓝染色结果显示:相较于对照组,模型组骨骺损伤明显并形成骨桥,然而加入脂肪和活血止痛汤干预后,骨骺损伤明显改善,骨桥消失,脂肪中药组效果更为明显。免疫荧光结果表明:对比对照组,模型组VEGF、BMP2和IL-1β的表达均有明显增加;而相较于模型组,脂肪组和脂肪中药组的VEGF、BMP2和IL-1β的表达均有所降低,并且脂肪中药组的VEGF、BMP2和IL-1β的表达下降更为明显。结论:活血止痛汤联合脂肪填充治疗大鼠胫骨远端Ⅲ型和Ⅳ型骨骺损伤疗效明显好于单纯脂肪干预。

The powders of RE2Co17（RE=Y, Ce, Nd, Ho, Er） and Ho x Co100–x（x=6, 8, 10, 12） alloys were prepared by the arc melting method and high-energy ball mill process. The compositions and morphologies of the alloys were characterized by X-ray diffraction（XRD） and scanning electron microscopy（SEM）, and the microwave absorbing properties were studied by a vector network analyzer. The results showed that the alloy of Y2Co17 had better absorbing properties at low frequencies and its lowest reflectivity value was –9.5 d B at 3.8 GHz. The lowest reflectivity value of Ho2Co17 alloy was –13.7 d B at 7.02 GHz and it obtained large absorbing bandwidth. Reflectivity value less than –5 d B was from 5.1 to 10.2 GHz. When x=6 and x=8, the alloys of Ho x Co100–x consisted of Ho2Co17 phase and Co phase. They had good radar absorbing properties. With increase in Ho content, the minimum reflectivity value worsened and the absorbing peak frequency shifted toward higher frequencies. But when x=12, the absorbing peak frequency shifted toward lower frequencies but the minimum reflectivity value worsened.

由于生产工艺复杂、制造流程长、生产量大等特点,砂型铸造产品存在质量波动大、质量溯源难等问题。近年来,虽然随着ERP、MES等信息管理系统的引入,铸造企业能够收集到的数据更多,但现有的这些信息并没有转化为知识,或只有少量数据被利用。由此,提出了一种基于华铸ERP系统的数据挖掘方法,在信息化管理的基础上,对收集的所有数据进行深度挖掘分析,挖掘结果由数据表、散点图、饼状图等方式展现。同时,还根据数据的关联关系,通过神经网络实现了对不同工艺参数产品的质量预测,以提升企业产品质量管控能力,提高企业效益。

To elucidate the variations in mass concentrations of organic carbon(OC)and black carbon(BC)in PM_(2.5) and their light absorption characteristics in Lanzhou,we conducted one-year online measurements by using a newly developed total carbon analyzer(TCA08)coupled with an aethalometer(AE33)from July 2018 to July *** mean OC and BC concentrations were 6.4±4.4 and 2.0±1.3μg/m^(3),*** seasonal variations were observed for both components,with winter having the highest concentrations,followed by autumn,spring,and *** diurnal variations of OC and BC concentrations were similar throughout the year,with daily two peaks occurring in the morning and evening,respectively.A relatively low OC/BC ratio(3.3±1.2,n=345)were observed,indicating that fossil fuel combustion was the primary source of the carbonaceous *** is further substantiated by relatively low biomass burning contribution(f_(biomass):27.1%±11.3%)to BC using aethalometer based measurement though f_(biomass) value which increased significantly in winter(41.6%±5.7%).We estimated a considerable brown carbon(BrC)contribution to the total absorption coefficient(b_(abs))at 370 nm(yearly average of 30.8%±11.1%),with a winter maximum of 44.2%±4.1%and a summer minimum of 19.2%±4.2%.Calculation of the wavelength dependence of total b_(abs) revealed an annual mean AAE_(370-520) value of 4.2±0.5,with slightly higher values in spring and *** mass absorption cross-section of BrC also exhibited higher values in winter,with an annual mean of 5.4±1.9 m^(2)/g,reflecting the impact of emissions from increased biomass burning on BrC concentrations.
