Although hasten of near future of upriver cooking benzene is firm, but the range that the market rises is not big, each manufacturer is maintained more move smoothly, the amplitude modulation on shipment price is lesser, to suitable anhydride market prop up gradually firm, if crude benzole market goes high further, driving the possibility that cooking benzene rises is not to do not have, the crude benzole stock of manufacturer of each cooking benzene and benzene hydrogenation manufacturer is not at present much, the crop of cooking benzene is not big, market supply of goods is not much, do not eliminate small to walk along high probability.

虽然上游焦化苯近期趋稳，但市场上涨的幅度不大，各厂家多维持平稳运行，出货价格上调幅度较小，对偏苯三酸酐市场的支撑渐稳，若粗苯市场进一步走高，推动焦化苯上涨的可能性不是没有，目前各焦化苯厂家和苯加氢厂家的粗苯库存并不多，焦化苯的产量不大，市场货源不多，不排除小幅走高的可能。

Five main phenomena were found, firstly, the high plasticity clay could well suitable to large deformation, and had strain-hardening behavior obviously, as well as, the little dilatancy; secondly, there was no correlation between stress paths and shear strength but the stress-strain relations were influenced by stress paths; thirdly, the little stress increment ratio, the higher increase speeding of shear stress and breaking strength under the condition of same initial normal stress; the fourth, the relations between normal strain and normal stress in simple shear test was consistent with which in the single-direction compression test, if there was no dilatancy; the last, the curve of relation between stress ratio and shear strain could be well simulated by hyperbola.

试验结果表明，高塑性粘土能够较好地适应大变形，接触面剪应力与切向应变关系呈剪切硬化型曲线，法向剪胀不明显；接触面剪切强度与应力路径无关，应力应变关系与应力路径密切相关；初始法向应力一定，应力增量比越小，剪应力增长越快，对应的破坏剪应力也越高；无剪胀发生情况下，法向应变与法向应力关系曲线与单向压缩试验具有一致性；应力比与切向应变呈良好的双曲线关系。

This topic uses the switching mode is the entire bridge all controls the rectification filter, moreover the power source has also utilized the soft switch technology, causes its loss to reduce obviously, the DC-DC transformation use cuts the wave boosted circuit to realize, the structure is simple, the transfer efficiency is high; Selects the small breakover resistance, the high shutter speed P60N06 tube for the switching valve, to select the quick recovery diode rectification, reduces the reverse breakover time, reduces the loss.

本课题采用的开关方式是全桥全控整流滤波，而且电源还运用了软开关技术，使它的损耗明显降低，DC-DC变换使用斩波升压电路来实现，结构简单，转换效率高；选用小导通电阻、高开关速度的P60N06管为开关管、选用快速恢复二极管整流，减少反向导通时间，降低损耗。

The simultaneity use of Xiao Er Chuan Ke Ye and Cang Er Zi San intervening asthma and allergic rhinitis,comparing simply use Xiao Er Chuan Ke Ye,has the predominance in prolonging time of introducing asthma and reducing the frequency of nodding breathe,which indicated that the treatment of allergic rhinitis has great importance in asthma control and lessen the degree of asthma(frequency of rat nodding breath).3,The combination high-dose group has better therapeutic effect than dexamethasone group,all Chuan Ke Ye groups and combination low,medium group in the prevention and control of allergic rhinitis symptoms,reduced airway hyper responsiveness,while in improving breath difficulties combination high-dose group has similar effect with western medicine group,and better effect than all Chuan Ke Ye groups and combination low,medium group.Its efficacy increased with the prolonging of treatment time,but fewer side effects,which makes the application safer and more reliable.4,Xiao Er Chuan Ke Ye combining with Cang Er Zi San can obviously improve the pathological changes in rats with bronchial airway remodeling,reducing the serum TGF-β1,IL-4,ECP levels,increasing the level of serum IFN-γand the imbalance IFN-γ/ IL-4 ratio.

而运用小儿喘咳液合苍耳子散同时干预哮喘与过敏性鼻炎，较之单纯使用小儿喘咳液治疗哮喘，其在延长引喘时间、减少点头呼吸频度等方面有明显的优势，说明过敏性鼻炎的治疗，对于控制哮喘发生，减轻哮喘发作的程度，有着重要的意义。3、大剂量的合方在预防和控制过敏性鼻炎症状、降低哮喘气道高反应性方面疗效较地塞米松对照组、喘咳液各剂量组及合方小、中剂量组更优，而改善呼吸困难方面则与西药组相当，优于喘咳液各剂量组及合方小、中剂量组，且其疗效随着治疗时间的延长而增加，但副作用更少，使用更加安全可靠。4、小儿喘咳液合苍耳子散能明显改善气道重塑大鼠支气管的病理改变，同时降低血清TGF-β1、IL-4、ECP水平，提高血清IFN-γ水平及失衡的IFN-γ/IL-4比值。
