The risk social theory is reshaping people's risk consciousness and the concept of crisis response. Though the crisis consciousness can help us to take preventive measures, potential and inevitability of risk and uncontrollability and emergency of crisis and risk make us incapable of facing sudden risks and crisis. China's current crisis management mechanism has just started.

风险社会理论重塑着人类的风险意识与危机应对观念，如果说危机意识有助于我们防患于未然，但风险的潜在性与不可避免性，风险与危机的不可控性与紧急性，让我们在突发的危机到来时，不能不直面风险与危机。

Aimed at the difficulty to extract the fault information of a low speed shaft in a large gearbox, wavelet analysis was used to realize the local analysis of signals in a time and frequency domain simultaneously. The signals were dissembled to a sieres of compactly supported wavelet bases non-redundantly and without leaking.

针对大型齿轮箱低速轴故障信息难以提取的问题，采用小波分析方法对故障数据进行处理以实现信号在时/频域的局域性分析，将其无冗余、无泄漏地分解到一组具有紧支撑性的小波基上。

Fifteen one-layered fabrics with different texture, density of fabric and fiber disposition were designed and woven before the designation of medical barrier fabrics.

在设计医用屏蔽织物之前，设计与试织了十五种具有不同织物组织、经纬密度和原料配置的单层织物，通过对它们进行性能测试和分析，探讨织物组织结构对其拒液性和透湿性的影响，得出了织物组织、纤维细度、织物紧度、织物达到高密的方法等几个因素影响这两种性能的主要规律，为医用屏蔽织物的开发奠定了理论基础。

In order to produce lightweight cashmere and wool products of fashion with low cost and high added-value,a appropriate mixing ratio of water-soluble PVA fiber,cashmere and high-counts wool is selected,oil pick-up and moisture of blended top wool are strictly controlled,yarn twist and weaving tightness are carefully designed,and the vinylon dissolution process is optimized.

结果表明：水溶性PVA纤维所占混纺比例越高，可纺纱线密度就越低，但其所占比例过高则会造成坯布紧度及织造难度增大，退维后织物中纱线条干均匀度差，织物结构松烂；水溶性PVA纤维所占比例过小，则不易混合均匀，可纺纱线密度降低得少，达不到轻薄产品的要求。
