Botulinum toxins were first researched in the late 1960s to treat neurological disorders and for that otox were first approved by the FDA in 1989 to treat eye muscle disorders like blepharospasm, uncontrollable blinking, and strabismus, crossed eyes.

肉毒毒素的研究，首次在六十年代后期治疗神经系统疾病，并为此otox首次核准由美国食品暨药物管理局在1989年治疗眼部肌肉疾病如眼睑痉挛，无法眨眼，斜视，眼划线。

This study is to give a solution for the estimation of flash point for mixtures, the necessity for classification of flammable liquids. The traditional models for predicting flash point of mixtures usually by the activity coefficient approach. However, the parameters of activity coefficient were regressed from phase equilibrium data in the literatures. If there is no such parameter in literatures for the desired mixture, the model cannot predict the flash point oft hat mixture. Thus, this research aims at the improvement of deficiency of the flash point prediction models in the literatures by useing UNIFAC (Universal Quasi-chemical Functional Group Activity Coefficient) equation, Dortmund-UNIFAC equation and Lyngby-UNIFAC equation. In this study, we were aim at the prediction model for miscible mixtures.From the result, it is suggested to use different type of UNIFAC equation to estimast activivity coefficient in the predition of flash point for different mixture type.

易燃液体分类的主要依据参数为闪火点值，因此本研究目的为解决易燃液体中混合物分类时所面临到的闪火点值缺乏的问题，而在过去文献中所提出的闪火点预测模式会使用到活性系数，但这些模式使用到的活性系数均需要相平衡的数据以回归其所需参数，若所欲估算闪火点的混合溶液文献上未有相关参数，则无法有效利用闪火点预测模式估算其闪火点，因此针对文献中现有闪火点预测模式的缺点，利用描述液体混合物活性系数UNIFAC (Universal Quasi-chemical Functional Group Activity Coefficient)方程式、Dortmund-UNIFAC方程式和 Lyngby-UNIFAC方程式，建立发展一闪火点预测模式，而本研究以互溶溶液为对象。

I can't think of another industry that still has that lack of visibility over its networks, says Heather Daniell of New Energy Finance, a research firm in London.

我无法想象还有哪个产业对其网络如此缺乏监管，伦敦新能源金融研究公司的Heather Daniell这样说道。

123I-IaraU was deficiently evidenced as a probe to monitor gene expression in the Tramp-C1/HSV1-sr39tk system.

本研究结果无法提供充分的证据显示碘－123-IaraU在Tramp-C1/IL3-tk系统可作为基因探针。

Researches show that the acquiring action has brought forth remarkable influence on acquiring firms, the traditional earning related indexes cannot evaluate acquiring performance precisely, and the long-term performance of acquiring has a meliorative trend.

研究发现，收购活动对主并企业绩效有显著负向影响，传统盈利指标无法准确评价收购绩效，主并企业长期收购绩效有改善的趋势。

Savolainen thought that there were at least six founders existing in the origin center, because clade A structure was too complicated to decide how many founders were contained in it.

另外，在Savolainen等人的研究中，由于支系A的结构非常复杂，因而无法判断其中包含了几个建群者，所以在他们的结论中只是笼统地给出，现代家犬的起源—线粒体DNA的研究起源中心的母系建群者不少于6个。

One year later, Slit was confirmed as the ligand of Robo and the Slit-Robo signaling is know involved in the repulsive effect of the commission axons crossing the mid-line, and also involved in the repulsive effect of the guidance of neuronal migration and leukocyte migration as well.

而对 Slit 功能展开的研究起于1998年，先是发现其受体 Robo突变型果蝇的中线处交叉神经元的导向发生缺陷。1999年的一系列遗传和生化的研究又发现，分泌性因子 Slit 正是 Robo 的配体， Slit － Robo 信号起到了排斥一些轴突，使之无法穿过中线的作用。

Secondly, analyze the environment and the situation of "JX PEMS", pointed out the current main issue, analyzed the development opportunity and the threat which "JX PEMS" faces, had pointed out the support of national related policy, huge demand from the Chinese express service market and so on, has provided the development space for the postal express mail service. At the same time, pointed out the high request to the express service corporation, the new threat from the express service market comprehensive opening; analyzed the advantage and weakness of "JX PEMS ",pointed out the postal service brand and the network are "the magic weapon" of "JX PEMS". But the unreasonable system, the rockbound mechanism, the outdated management and technical causes it to be unable to meet the express service market demand well.

其次，就江西邮政速递公司进行了环境与形势分析，指出了当前存在主要问题，研究分析了江西邮政速递公司面临的发展机会和威胁，指出了国家有关政策的扶持和中国快递市场巨大需求等为邮政速递业务发展提供了发展空间，同时，指出快递市场对快递企业的高要求、快递市场全面开放带来新的威胁；研究分析了江西邮政速递公司的优势和劣势，指出邮政品牌和网络是江西邮政速递的&法宝&；而体制不顺、机制不活、管理和技术落后等使之无法更好地满足市场需求。
