Through a study of 504 cases of observation group with eye-signs in blood stasis syndrome and 112 cases of control group without eye-signs in BSS,it has been found that in the observation group, the scores of the blood concentration,viscosity, aggregability and coagulability,level of plasma thromboxane B2(TXB2),and the ratio of TXB2/6-keto-PGF1 α were obviously higher than those in the control group,but level of 6-keto-PGF1 α was obviously lower than that in the control group; the above-mentioned param...

本研究通过对504例血瘀证目征观察组和112例非血瘀证目征对照组研究发现，观察组血液浓稠性、粘滞性、聚集性和凝固性积分值，血浆血栓素B2（TXB2）水平、TXB2／6－酮－前列腺素F1α（6－keto－PGF1α）比值均明显高于对照组，而血浆6－keto－PGF1α水平明显低于对照组，表现为血液高粘滞综合征者占90.08％，明显高于对照组2.68％，两组比较均有非常显著性差异（P＜0.001）。本研究为血瘀证目征提供了部分病理基础。

When the sodium lauryl sulfate and p-octyl polyethylene glycol phenyl ether is used and its level in 3% and 6: 4 ratio, the polymerization process has the lowest coagulum and the highest monomer conversion. Higher reaction temperature and more level hydroxyl value lead to more coagulum, the latter also lead to larger particle size. The acid value has larger influence on viscosity and coagulum, there exist a best range. The emulsion particle size is larger for its hydrophilicity, most of its particles are connected together.

在含较高亲水单体的乳液聚合体系中，难以制得稳定的预乳化液，不能采用工业生产中常用的预乳化工艺，而只能采用混合单体直接滴加的方法；由于单体混合物的亲水亲油值较高，用阴离子型乳化剂十二烷基硫酸钠和非离子型乳化剂聚乙二醇辛基苯基醚混合，用量为单体总量的3％，且比例在6：4时，乳液聚合时具有最低的凝聚物含量和最高的单体转化率；乳液聚合反应温度升高，可以提高单体转化率，增加反应速度，但凝聚率相应提高；随着羟基单体含量的增加，聚合过程中凝聚率增加，聚合物乳胶粒平均直径增加；羧基单体有一个最佳的用量（2.6％），过高或过低凝聚率均提高；羧基含量对乳液的粘度有较大的影响，当羧基含量较低时，羧基含量增加，乳液粘度增加明显；含羟基乳液粒子由于含亲水基团较多，使得乳胶粒径增大，乳胶粒子大多数互相凝聚在一起，处于凝聚态。

Because of the complexity of the coalification process and the diversity of the coal-level indicators ,it was induced that resulting in different coalification stages the coal-level indicators were significantly different and coal-division was rather difficult.

煤化过程的复杂性和煤级指标的多元性，导致不同煤化阶段中的各煤级指标显著不同，煤级划分比较困难。

Nerve repair at the level of spinal cord appeared as a new but challenging technique. The better understanding of regeneration from neurons and further refinement of instruments may push the brachial plexus surgery to a new level. Sensory and motor differentiated nerve coaptation plays an important role in the free neurovascular muscle transplantation due to the significance of motor axons for the flap reinnervation.

For the moral grounds of the thesis of self-ownership in intuitional level, Cohen argues that the moral intuition of aversion to slavery gives no cause for more criticism, but it can't follow that rejection of the thesis of self-ownership is tantamount to endorsement of slavery. And the moral intuition of not permitting others'deploying any part of one's own body by coersion can't motivate moral agents to identify the thesis of self-ownership. For the moral grounds of the thesis of self-ownership in theoretical level, Cohen argues that rejection of the thesis of self-ownership is neither tantamount to endorsement of treating people as means rather than as ends, nor tantamount to endorsement of threatening human autonomy.

就自我所有命题在直觉层面的道德依据，柯亨论证道，厌恶奴隶制这种道德直觉本无可厚非，但并不能据此得出拒绝自我所有命题就意味着对奴隶制的认可这个结论，而不允许他人强制使用自己身体的任一部分这种道德直觉，也不足以使道德主体去认同自我所有命题；就自我所有命题在理论层面的道德依据，柯亨论证道，拒绝自我所有命题不仅不意味着以手段而非目的来对待人们，而且也不意味着对人类自主的限制。

How had caught the adjustment of structures of next level agriculture industry, the author puts forward, what serious problem does not depend on the market-in concept of the farmer is strong weak, whether to also want specific and directive farmer to plant in basic level government what does move, and the development that depends on wanting to be captured cogently and catch good business to organize.

如何抓好下阶段农业产业结构的调整，作者提出，重要的问题不在于农民的市场观念的强弱，也不在基层政府是否要具体指导农民种什么调什么，而在于要切实地抓住和抓好商业组织的发育。

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
