By introducing the selective identity and selective chosen message attack model, this paper proved unforgeability of the scheme under the hardness of DHI problem and its indistinguishability against selective identity and chosen ciphertext attack under the hardness of DBDHE problem.

通过引入了选择身份和选择消息攻击的安全模型，利用DHI问题的困难性，证明了方案的不可伪造性，同时利用DBDHE问题的困难性，证明了方案在选择身份和选择密文攻击下的不可区分性。

Nature of tumor margin, cellular pleomorphism, frequency of mitoses and tumor necrosis were statistically appropriate composition in histological diagnosis of phyllode tumor. Wide local excision is preferred for the benign and borderline phyllode tumor, while simple mastectomy is indicated for recurred borderline and malignant, but tylectomy should be abolished in the treatment of phyllode tumor.

良性、交界性和恶性叶状肿瘤应废止以往常用的肿物单纯切除术式；对于良性和交界性肿瘤至少应选择肿物连同周围2cm正常乳腺组织一并切除的扩大切除术；复发的交界性和恶性肿瘤要选择乳房单纯切除术式。

We define two security notions of identity based proxy multi-signature. One is existentially unforgeability under an adaptive chosen-message attack, an adaptive chosen-warrant attack and a given identity attack. The other is existentially unforgeability under an adaptive chosen-message attack, an adaptive chosen-warrant attack and an adaptive chosen-identity attack.

本文给出了基于身份的代理多重签名的两种安全定义，第一是适应性选择消息攻击，适应性选择授权文件攻击，以及给定身份攻击下的不可存在性伪造；第二是适应性选择消息攻击，适应性选择授权文件攻击，以及适应性选择身份攻击下的不可存在性伪造。

This paper defines a strong security model for multi-recipient signcryption scheme in the random oracle model, which is semantically secure against adaptive chosen-ciphertext insider attack, existentially forgeable chosen-message attack and anonymous chosen-ciphertext insider attack. By analyzing, we point out that Li-Hu-Liu Multi-Recipient Signcryption Scheme is insecure against the adaptive and anonymous chosen-ciphertext insider attacks.

摘要在随机预言模型下定义了一个多接收者签密方案的强安全性模型，该模型满足适应性选择密文内部攻击安全性、选择消息抗存在性伪造和密文匿名安全性；通过分析指出， Li、Hu和Liu等人提出的多接收者签密方案，不具有适应性选择密文内部攻击安全性和密文匿名性，并给出所定义强安全性模型中的攻击方法；随后提出改进方案，该方案在强安全模型中证明是安全的。

objective to evaluate the efficacy of water soluble vitamin for the treatment of hypodynamia and vertigo of drug induced.methods 160 patients with hypodynamia and vertigo after injected the antibiotics,expand the afferent medicine and other the medicine(expel the medicine with the result that high blood pressure,low blood pressure,low blood sugar but appear the above symptom),were randomly divided into two groups:one of the normal regulations treatment(glucose +the vitaminc+vitamin b6),,the other group use the water soluble vitamin,contrast to observe the efficacy of the treatment after a week.results the effect of therapy was obviously better than that of the control group(χ2=4.44,p.05).conclusion the water soluble vitamin can improve the hypodynamia and vertigo of drug induced symptom better.

摘 要］目的：探讨用水溶性维生素治疗药源性乏力、眩晕疗效。方法：选择160例注射抗生素、扩血管药及其他药物后出现乏力、眩晕症状的患者(排除药物所致高血压、低血压、低血糖而出现以上症状)。随机分为二组：一组常规治疗(葡萄糖+维生素c+维生素b6)；二组用水溶性维生素治疗，治疗时间为一周，对比观察其疗效。结果：观察组治疗有效率与对照组比较差异有统计学意义(χ2=4.44，p.05)。结论：水溶性维生素能更好地改善药源性乏力、眩晕症状。

The main findings of the empirical analysis include: 1 The decisions concern the choices of auto ownership, mode to work, and auto use were made simultaneously and interrelatedly. 2 The decline in correlation between the choices of auto ownership and use as the number of vehicle increase indicated that to own multi-vehicles in not necessary due to the demand for auto use. 3 Both price elasticity and income elasticity for auto ownership are low. This evidence implies that auto has become a kind of necessity for household. Therefore, the effect of decreasing the tendency of auto growth by means of increasing the cost of owning auto would not be significant. The price elasticities of auto use are between -0.48 and -0.78. 4 There are same underlying factors influencing auto ownership, mode to work, and auto use including: parking time at residential location, accessibilities to work location by auto and transit, auto use unit cost, and the percentage of auto use for work. These factors indicate a direction for the formatting of future automobile policies.

本研究以台湾地区之家户个体资料从事实证分析，实证分析之主要结论如下：1小汽车持有数量、工作者工作运具选择、与小汽车使用量等选择间确有相关与联立性存在；2小汽车持有数量选择与小汽车使用量选择间之相关性会随小汽车持有数量的增加而降低，显示选择持有多部小汽车并非完全基於小汽车使用之需要；3小汽车持有之价格弹性与所得弹性均偏低，显示小汽车已成为民生必需品，欲以提高小汽车持有成本之价格手段来抑制小汽车持有，并无法竟其功，小汽车使用需求之价格弹性则在-0.48与-0.78间；4影响小汽车持有数量、工作者工作运具、与小汽车使用量等选择主要之相关或共同因素包括：家户附近停车状况、私人运具与大众运输工具之工作可及性、小汽车单位使用成本、与小汽车工作使用比率等，以上这些影响因素可为日后小汽车相关政策的研拟提供一方向。

Besides, the effects of light and temperature on stomata have not been modelled in any mechanistic model.

在第一章中，通过综述气孔对环境因子响应的数学模型的文献，发现目前对描述和模拟气孔行为的经验模型和机理模型是脱节的，可供选择的气孔模型还不能满足理论分析和实际应用的需要；经验模型没有机理的支持，不能用于理论分析，没有普适性；机理模型都过于复杂，而且其中的一些参数难以确定，所以它们还只能作定性模拟，不能作定量预测，另外，对于光强和温度的影响还未见有人模拟。

The results of calculation will be fundmentally consistent with the experimental values.In addition, we calculated dibenzene chromium and its derivatives, ferroceneand its derivatives. The former had higher symmetry. We studied the substituenteffects by calculating their NMR spectra. The results show that: when we add asubstitute group on one ring of dibenzene chromium, the substitute group will affecttwo benzene rings. The effect is similar to the effect of branched alkanes, namely:the effect on neighbouring groups has transmissibility. Furthermore, the nearer theneighbouring group is, the stronger the effect is. This effect is observed not only onthe substituted ring, but also on the unsubstituted ring.

此外，我们重点计算了二苯铬及其衍生物和二茂铁及其衍生物的核磁共振谱，其中二苯铬及其衍生物选择的是对称性较好的体系，通过计算其核磁共振四川师范大学硕士学位论文谱，探讨其取代基效应，结果表明：在二苯铬的一个环上引入取代基后，取代基对两个苯环的影响，类似于支链院烃引入取代基后的影响：即对邻近基团的影响有传递性，并且对离得近的作用强，对离得远的作用弱，这种作用不仅体现在连有取代基的环上，也体现在没有带取代基的环上。
