Besides, I also find that firms report negative earnings for fiscal year, which have less current and future earnings response coefficient than report positive earnings, and firms report negative cash flows from operating for fiscal year, which have less current cash flow response coefficient than report positive cash flows. Indicating that firms report negative earnings or cash flow, because losses are more transitory and which stock prices less information but which future cash flow response coefficient more than report positive cash flows. Inference of this study because cash flow have substance effect, so when firms have negative cash flows investor more care about it, which have more cash flow response coefficient, and further find while distinguishing the degree of sophisiticated investor, investor the sophisiticated degree proportion is higher. Because they know information of the earnings, firms have more degree of shareholder sophistication for fiscal year, which have more current and future earnings response coefficient than which have less.

此外，本文也发现报导损失之公司，其当期及未来盈余反应系数较报导利润之公司低，以及公司报导营业活动之现金流量为负时其当期营业活动之现金流量反应系数低於报导营业活动之现金流量为正之公司，显示公司报导损失或营业活动之现金流量为负时，因为通常都是暂时性的故其股票报酬的资讯性较低，不过其未来营业活动之现金流量反应系数高於报导营业活动之现金流量为正之公司，本研究推论因为现金流量是有实质的效果，所以当现金流量为负值时投资人应该会比较关注，所以其反应系数较高，而进一步发现当区分投资人之精明程度时，投资人精明程度比重较高，因其会辨识盈余资讯而认为公司进行损益平稳化会增加其资讯内涵，故当期及未来盈余反应系数相较於投资人精明程度较低者高。

Wavelet multi-resolution analysis is applied to decompose the signal into multiple-level and the wavelet coefficient modules of its high-frequency components are obtained. The wavelet coefficient modules of a broken signal can be extracted by software demising. The threshold of demising is decided by the difference between the wavelet coefficient modules of a broken signal and those of a noise. The wavelet coefficient modules of the broken signal were shown in different levels, then the faults can be detected and distinguished by the integrated features of the variant levels' wavelet coefficient modules.

利用小波多尺度分解技术，将信号进行多尺度的小波分解，得到不同尺度下的信号高频分量的小波系数模值，并根据奇变信号和噪声信号小波系数模值的差异，采用软阈值去噪法，对其高频分量小波系数进行去噪处理，获取不同尺度上突变信号的小波系数模值，实现对故障的检测，并可根据不同尺度上小波系数模值的对应关系，实现对多重并发故障的区分。

Furthermore, transfer coefficient between total content and variable speciation including acid-soluble/exchangeable, reducible, oxidisable fraction of heavy metals are different. Transfer coefficient of total Cr is 0.65 in tailings area, but that of variable speciation is 0.26. In contrast with Cr,transfer coefficient of total Ni is 0.26, but that of variable speciation is 0.67. The similar characteristics on Pb and Zn in cultivated soil, namely, transfer coefficient of total Zn is high, but low for variable speciation, which is reversed for Pb. Transfer coefficient of total content and variable speciation in abandoned soil are low compared with above two fields soil, especially, variable speciation of Cu and Ni are not transported almost down soil profile.

重金属总量和活性态（包括弱酸提取态、可还原态、可氧化态）迁移率也表现出很大差异，尾矿区土壤Cr总量迁移率较高为0.65，而其活性态迁移率较低为0.26，Ni与Cr迁移特征完全相反，总量迁移率为0.26，而活性态迁移率为0.67；农田土壤中Pb总量迁移率低而活性态迁移率高，Ni与Zn特征相似，总量迁移率高而活性态迁移率相对较低；大棚地土壤中重金属迁移率均较低，Cu和Ni活性态几乎未发生向下迁移。

Single factor experiments were done with the factors including the width of protrusion and the trolley's velocity, which showed that the surface frictional coefficient decreases with the width of protrusion increasing, and doesn't change with the trolley's velocity changing, which was consistent with the results of the orthogonal experiment. A theoretical model of the horizontal projection of a corrugated bionic surface's contact area was built, which showed that the contact area's horizontal projection decreases with width and interval increasing respectively and that the ratio of the contact area's horizontal projection and the vertical load decreases with the vertical load increasing. It indicated that the surface frictional coefficient decreases with the above three factors increasing respectively. Finite element modeling and analysis of interactions of a plate and soils was done using ANSYS, which showed that the plate frictional coefficient is little relative to soil elastic modulus and decreases with vertical surface pressure and that trolley's pull and vertical displacement of bionic surface's control pilot keep constant almost during the plate being pulled. Finite element modeling and analysis of interactions of a corrugated bionic surface and soils was done using ANSYS, which showed that surface frictional coefficient is little relative to soil elastic modulus and decreases with bionic surface's structural parameters and vertical pressure increasing. However, the three factors all didn't affect the surface frictional coefficient remarkably on the condition of 90% dependability. For the first time, bionic surfaces were applied to screw piles, which formed bionic screw piles, and the contrast experiments showed the bionic screw pile had certain resistance-decreasing effects.

建立了波纹型仿生曲面与土壤的接触面积的水平投影的理论模型，表明接触面积的水平投影A随着波纹型仿生曲面突起宽度、两相邻突起间距的增大而减小，接触面积的水平投影与波纹型仿生曲面表面垂直载荷之比随着波纹型仿生曲面表面垂直载荷的增大而减小，进而得出仿生曲面摩擦系数随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小；利用ANSYS软件对平板与土壤的相互作用进行了有限元建模与分析，表明平板摩擦系数与土壤弹性模量关系不大，而随着表面垂直载荷的增大而减小；平板牵引过程中台车牵引力和仿生曲面控制节点垂直方向位移基本保持不变；利用ANSYS软件对波纹型仿生曲面与土壤的相互作用进行了有限元建模与分析，表明波纹型仿生曲面系数在一定范围内基本不受土壤弹性模量的影响，随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小，但在可信度为90％的前提下，三个因素影响都不显著；首次将波纹型仿生曲面应用于与土壤作用方式以挤压为主的螺旋桩，形成仿生螺旋桩，并与普通螺旋桩进行了沉桩对比试验，表明波纹型仿生曲面应用于螺旋桩桩体表面具有明显的降阻作用。

Along with the recovery of semidarkness region, ischemia and anoxemia state is getting improved, and VEGF is reduce.(6) As there are PCNA and VEGF masc cells in brain injured region, we could conclude that, after brain ischemical reperfusion injury, there are blood vessel regeneration phenomenon. Acupuncture could promote blood vessel regeneration, recovery blood supply sufficiently and quickly, and promote the recovery of brain injury region.(7)The VEGF masc cells percentage of inhibitor group is lower than acupuncture group. It state that the effect of acupuncture promote VEGF is partly depend on the existing of eNOS.

实验结论：(1)脑缺血再灌注损伤后大鼠的肢体运动功能发生改变，针刺可以促进肢体功能恢复；(2)脑缺损伤区可见PCNA阳性细胞，存在细胞再生现象，针刺可以增强损伤区PCNA的表达，有利于损伤的修复和功能重建；(3)针刺组和模型组14d时缺血损伤区PCNA阳性细胞百分比低于7d组，随着损伤逐渐得到修复，细胞增殖现象减弱；(4)脑缺血损伤区可见VEGF阳性细胞，存在内皮型细胞再生现象，针刺可以增强损伤区VEGF的表达，有利于脑损伤后保护和缺血区血管再生；(5)针刺组和模型组14d时缺血损伤区VEGF阳性细胞百分比低于7d组，随着缺血损伤的修复，缺血缺氧状态得到改善，产生的VEGF减少；(6)由于脑损伤区同时出现PCNA阳性细胞和VEGF阳性细胞，前者是增殖细胞的标志，后者是促进血管再生的重要因子，可以推断，脑缺血再灌注损伤后脑内存在血管再生现象，针刺可以促进损伤区的血管再生，更迅速而充分的恢复损伤区的血供，促进脑损伤区的修复；(7)抑制剂针刺组脑损伤区VEGF阳性细胞百分比与针刺组相比有不同程度的降低，说明针刺促进缺血损伤区VEGF表达部分依赖eNOS的存在。

Objective To study the relationship of endangium proliferation and the expression of metalloproteinases and tissue inhibitors of metalloproteinases after angioplasty of iliac artery in rabbits to investigate the probable mechanism of composite Danshen pill in prevention and treatment of restenosisMethods 30 white male rabbits of Japan （the average body weight was 25～30 kg）were randomly divided into 3 groups:normal control group,model group (intima destroyed by balloon and given hypercholesterol diet),CDP group (intima destroyed by balloon and given hypercholesterol diet plus drug CDP 150 mg/d),10 ones each groupResults The results of iliac artery angiogram and the analysis of pathology:there were lumens stenosis,thinner intima,smaller intima area,in CDP group compared with those in model group,and ratio of intima and tunica media thickness and area among each group (P＜001)Immunohistochemistry analysis:the MMP2,MMP9,TIMP1,TIMP2 in model group significantly increased than those in control group (P＜001)The CDP group had lower MMP2 and MMP9 expression,higher TIMP1 and TIMP2 expression,and increased MMP2/TIMP1,MMP9/TIMP2 than model group (P＜001)The thickening of vascular neointima and stenosis degree of vascular lumen were relevant to MMP2 and MMP9 (r=0896,P＜001)Conclusions MMP and TIMP play the very important role in the restenosis process of arteryCDP could inhibit the thickness of vascular neointima after balloon injury,the probable mechanism of which may be inhibiting collagen formation,smooth muscle immigration and decreasing hyperplasia of intima by interfering expression of MMPs and TIMPs

目的 研究兔髂动脉成形术后血管内膜增生和基质金属蛋白酶及其抑制物表达之间的关系，探讨复方丹参滴丸预防再狭窄的可能机制。方法健康成年二级雄性日本大耳白兔30只，平均体重25～30 kg。随机分为3组：正常对照组10只，模型组10只（球囊内膜剥脱加高胆固醇饮食），治疗组10只（球囊内膜剥脱加高胆固醇饮食以及复方丹参滴丸150 mg/d）。结果兔髂动脉造影、血管病理图像分析检测结果：①复方丹参滴丸组较模型组血管造影示管腔直径狭窄、内膜厚度减少、内膜面积减少、内膜厚度和中膜厚度比、面积比，各组之间有显著性差异(P＜001)。②免疫组化分析：模型组MMP2、MMP9、TIMP1、TIMP2表达均高于对照组（P＜001）；复方丹参滴丸组MMP2、MMP9的表达低于模型组，而TIMP1、TIMP2的表达高于模型组；TIMP1/MMP2、TIMP2/MMP9明显增加，差异有显著性（P＜001）。③内膜的增生以及管腔的狭窄程度与MMP2、MMP9有很好的相关性(r=0896，P＜001)。结论 MMP和TIMP在再狭窄形成中起重要作用；复方丹参滴丸能够明显抑制血管损伤后的内膜增生，可能的机制是通过影响金属蛋白酶MMP2、MMP9及其抑制物TIMP1、TIMP2的表达从而抑制胶原的生成、平滑肌的迁移、增生，而减少内膜的增生。
