Zidovudine may competitively inhibit the intracellular phosphorylation of stavudine. Therefore, use of zidovudine in combination with Stavudine is not recommended

齐多夫定会竞争性抑制司他夫定的磷酸酰化，因此禁止与齐多夫定联合用药。

The insiders consist of traditional insiders, constructive insiders, tippers, tippees and misappropriators. The inside information must be unpublished and sensitive to securities' prices. The formulas of counting the damages are proposed. The doctrine of liability fixation should adopt the principle of constructive wrongs. The securities law should directly construct the causality, which relieves the average investors' burdens of proof in order to protect their benefit.

本文提出应将内幕交易主体区分为传统内幕人、推定内幕人、泄露信息者、接受信息者、盗用消息者等几类，并分别予以阐述；内幕信息则需具有两个最重要的条件——非公开及价格敏感性；在损害事实的确定问题上，提出了计算受害方的损失数额的公式，并指出以内幕交易者的全部非法所得为限进行民事赔偿比较公平合理；鉴于受害者无法确知内幕交易者的主观心理状态，在归责原则上宜采过错推定原则；在因果关系的证明上，从保护受害者的角度出发，应采美国做法，立法直接推定因果关系存在，明确规定受害者有损害求偿权，而毋需承担因果关系的举证责任。

To investigate the role of prophylactic lamivudone in reducing the incidence and severity of hepatitis B in lympho- ma patients who were HBV carriers and received chemotherapy.The prophylactic lamivudine group consisted of 40 patients who were treated with oral lamivudine before and until at least 8 weeks after chemotherapy.The historical control group con- sisted of 116 patients who underwent chemotherapy without lamivudine treatment.

探讨慢性HBV携带的淋巴瘤患者化疗前预防应用拉米夫定在减少化疗后肝炎发生率以及严重程度方面的作用。40例患者化疗前及整个化疗期间口服拉米夫定，并持续用至化疗结束后至少8周以上；另外历史对照组116例患者未接受预防性拉米夫定口服。

Then, smooth actions of three controllers are assured. Using the definition of 'fuzzy transfer function', the approximate corresponding relationship between well-tuned parameter of PID liner controller and scaling gains of fuzzy controller is established.

在模糊控制器的参数整定上，借助于模糊传递函数的定义，建立了模糊控制器比例因子与PID线性控制器整定参数的近似对应关系，于是模糊控制器的最佳参数便可通过较少的试凑被整定出来，简化了模糊控制器的设计。

Introduces a switching step-response algorithm parameters of the self-tuning controller, through the actual temperature control systems, Relay oscillation parameters and self-tuning algorithm and the parameter auto-tuning analysis module, The algorithm proves the safety and setting time than the other two algorithms.

详细说明：介绍了一种基于开关阶跃响应算法的参数自整定控制器，通过在实际温度控制系统的应用，与继电振荡参数自整定算法以及的参数自整定模块进行分析比较，证明该算法在安全性及整定时间上明显优于其他两种算法。

An intermediate oil type hydrocracking catalyst has carrier prepared from amorphous aluminosilicon, alumina, assistant phosphorus, adhesive and extruding aid through mixing, shaping, drying, and then hydrothermal treating, and contains the oxides of metals in families VIB and VIII, and phosphorus.

The CLAMP analysis and methods of floral coexistence are two comparatively new methods for quantitative reconstruction of Tertiary. terrestrial paleoclimates which rely on data from fossil plants. Using these approaches will enhance Tertiary paleoclimate analyses from Yunnan Province considerably and change the style of analysis from qualitative to quantitative.

目前国际上古植被与古气候变迁关系的研究已从定性描述向定量化研究的方向发展。90年代以来，Wolfe与Mosbtugger分别发展的CLAMP和Coexistence Approach是利用化石植物定量化研究古气候的两种新方法，可用于定量化研究云南第三纪植物与古气候变迁，将是后续工作的重要方向。
