The results show that the proposed scheme can not only resist conspiracy attacks and forgery attacks essentially, but also provide anonymity and traceability simultaneously. In addition, itcan realize the unknowability ofgroup's secretby constructing a secure distributed key generation protoco.l As a resul,t the proposed scheme is more secure than the two schemes.

结果表明：该方案不仅能够从根本上抵抗合谋攻击和伪造签名攻击，而且在保证匿名性的前提下，能够真正实现签名成员身份的可追查性，同时通过构造安全的分布式密钥生成协议保证群私钥的不可知性，因此比现有方案具有更高的安全性。

Security analysis shows that this new scheme can not only resist the above-mentioned conspiracy attacks and forgery attacks essentially, but also provide anonymity and traceability simultaneously. Moreover, by constructing a secure distributed key generation protocol, the proposal realizes the unknowability of the group\'s secret.

分析表明：新方案能够根本抵抗合谋攻击和上述伪造签名攻击；在保证匿名性的同时可以真正实现签名成员身份的可追查性；通过引入可验证秘密共享并设计安全的分布式****生成协议，实现了****影子的可验证性以及群共享秘密的不可知性，系统安全性大大提高。

ConclusionThe extraction rate of volatile oils from Heracleum hemsleyanum Diels by supercritical CO2extraction process is higher than that of water vapor distillation,and the optimized extraction conditions are:extraction pressure 25MPa,extraction temperature 45℃ and flow rate of CO2 20L/h, and the yield of volatile oils is 0.65%.

结果通过各因素级差大小的比较可知：萃取压力的变化对萃取率的影响最大，萃取温度次之，而CO2流量对萃取率的影响最小。结论超临界CO2萃取牛尾独活挥发油的萃取率较水蒸气蒸馏法高，最佳萃取条件为萃取压力25MPa，萃取温度45℃，CO2流量20L/h，挥发油收率为0.65%。

The departure was corrected by the renaissance of the idea of nature as law of universe in Neo-Taoism in Wei-Jin times. But this idea chopped up the relationship of natural things and denied the knowability of the order the nature as well as the various theories in Pre-Qin times. So it might bring negative influence easily to the nature research.

魏晋玄学中的天道自然思想的复兴纠正了这种偏离，但它割断了自然事物之间的相互联系，而且同先秦诸子一样，否定了自然规律的可知性，对于自然界的探索容易产生消极情绪。

According to distribution of bryophytes on different substances, the frequencies of Bazzania albifolia, Heteroscyphus coalitus and Homaliodendron scalpellifolium in evergreen broadleaved forests of Daweishan Nature Reserve are highest; those of Macrothamnium macrocarpum, Bazzania fauriana, Ptychanthus striatus, Pogonatum cirratum and Thuidium cymbifolium are higher. Additionally, Aerobryum speciosum, Trachycladiella sparsa, Taxiphyllum subarcuatum, Aerobryidium levieri, Lepidozia wallichiana, and Leucobryum bowringii are relatively common.

根据大围山常绿阔叶林内苔藓植物在不同基质上的生长分布情况，结合其甲凡J}rg另出现的频度可知白叶鞭苔、双齿异粤苔、以及刀叶树平醉是大围山常绿阔叶林内的三大优势种；南木醉、厚角鞭苔、皱尊苔、刺边小金发鲜和大羽醉在大围山常绿阔叶林内出现的频率也很高；此外气鲜、散生粗带醉、钝叶鳞叶鲜、莱氏毛扭醉、瓦氏指叶苔、以及狭叶白发鲜等在大围山常绿阔叶林内也有一定数量的分布。

We found that CTC in chicken feces were nearly seldom degraded in photophobic condition.After 15 days, the degradntion rate of CTC at three different concentrations was 5.93％, 7.36％, 6.20％,respectively. But under the natural illumination, the degradation of CTC in chicken feces was very fast.After 15 days, the degradation rate of CTC at three different concentrations was 98.62％, 89.53％,95.98％, respectively.

在避光条件下鸡粪中的金霉素都比较稳定，经过15d的降解，三个不同初始浓度的药物降解幅度分别为：5.93％、6.20％和7.36％；而在自然光照条件下，鸡粪中金霉素降解都较快，在15d的试验期内，降幅达到89.53％、95.98％和98.62％，将鸡粪中金霉素浓度随时间的变化趋势进行曲线拟合，可知这种变化趋势符合一级动力学方程Ct=C_0e~。

The catalytic cracking of NNJ 150 over USHY, HZSM 5 and SAPO 34 catalysts presented as that the selectivity of light olefins over USHY was the lightest among the three calalysts with a quicker deactivation, while HZSM 5 showed a longer catalyst life and lower selectivity of light olefins, for SAPO 34, both the conversion and the selectivity of light olefins were the lowest.

实现吸热型碳氢燃料这种功能的关键之一是选择适当的化学反应。由于碳氢燃料的裂化是吸热反应，而催化裂化与热裂化相比，能降低反应的温度，因此催化裂化是实现吸热型碳氢燃料功能较好的途径之一。由热力学可知，燃料裂化生成乙烯、丙

According to XPS data, the surface basicity of active coke is mainly ascribed to the delocalized π electrons of carbon platelets.

由XPS数据可知。随着活性焦表面的氧含量的减少，离域π电子趋于活跃，活性焦的碱性增加，证实了碳原子平面层上的离域π电子是活性焦表面碱性位存在的主要原因。

Natural theology, or theism, occupies the middle ground between these extremes, and should have been disassociated both from the Gnostic position, that the mind can know everything, and from the Agnostic position, that it can know nothing concerning the truths of religion.

自然神学，或有神论，占用之间的中间，这些极端的，并应已disassociated无论从gnostic的立场，即心可以知道一切，从不可知论者的立场，即它可以一无所知，关于真理的宗教。

New Zealand, Australia and parts of the United States had already enfranchised women, and growing numbers of their British counterparts wanted the same opportunity.

可知had already enfranchised women这个谓语是一个正向的判断，因为如果新西兰对于妇女选举权问题的态度是负向的话，那么英国的妇女是不可能也想要相同的机会的。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
