Objective To study the condition of drug fast and changes of aetiology of blood infected.

The structure of insecticide and drug fast of insect

杀虫剂结构与昆虫抗药性

METHODS: The use of third-generation cephalosporins was analysed in respect to the amount of consumption of individual products in 1998~ 2001, the total amount of consumption of all kinds of cephalosporins each year and the number of cases infected by drug-fast bacteria and drug-fast rate.

方法：统计我院1998年～2001年第3代头孢菌素单品种用量和各年度第3代头孢菌素总量，以及各单品种每年耐药例数和耐药率。

Our results show that clinician must select antibiotic according to the drug sensitive test of diplococcus gonorrhoeae to prevent drug-fast bacteria multiple infection.

其结论是临床用药应参考淋病奈瑟菌药敏试验结果，合理选用抗生素，预防多重耐药菌株的产生。

Currently the development of antiviral drugs for pediatric exogenous fever in modern medicine is rather slow and their efficacy is not quite explicit. Overuse of antibiotics leads to an increase in drug-fast bacteria as well as a decrease in the immunity of children.

现代医学治疗小儿外感发热，抗病毒药物的发展比较缓慢，疗效尚待评估；抗生素的滥用，引起耐药菌的增多和儿童抵抗力的下降，各种副作用伤及儿童。

As a result of the frequent generation of the drug-fast bacteria, the available life of antibiotics becomes shorter and shorter.

由于耐药菌的不断产生，使得抗生素的使用寿命越来越短。

From the result of three-dimensional reconstruction based on the smoothing contours, we can see that the saw tooth drops and the visual effects improve significantly.

基于平滑处理后轮廓进行的三维重建，层间的锯齿现象明显减少，对象的可视化效果得到了明显的改善。

We found that the glaze belonged to opalescent glaze of splitting glass phase, and the primary opalescent phase was glass drops by XRD and SEM analysis.

借助于XRD分析和SEM分析，发现该系统乳浊釉为分相乳浊釉，主要乳浊相为分相液滴。

The measuring system can be directly applied to fast quantitative analysis for sugar content of fruit drops and the prediction accuracy can be up to95%.

该测量系统可以直接用于水果糖份含量的快速定量分析且预测精确度可达到95%。

Compared with some existing models, signal quantization and packet dropout compensation are more properly considered in this new model. A new model describing packet dropouts, time delays, signal quantization, and access constraint is proposed for the following reasons.

相比于已有文献，该模型更合理地考虑了量化和丢包补偿等问题。基于如下考虑，提出了一个同时描述丢包、时滞、量化和传输受限的新模型。

Dropout Compensation of Control Track ( CTL) in Video Tape

录像磁带控制信号磁迹（CTL）的失落补录

A new strategy based on forgetting factor method is proposed for packet dropout compensation.

针对控制信号丢包，提出了一种新的丢包补偿策略，即基于遗忘因子法的丢包补偿策略。

A New High Voltage Dropout Fuse with Current Limiting Characteristics

There is a drop in blood pressure and the heart rate falls.

血压下降，心率下降。

If there is a constant drop in pressure, there is a leak in the system.

如果压力不断减小，则说明系统存在泄漏。

They discovered a drop in pressure in the fuel cells that supplied electricity.

他们发现供电的燃料电池电压下降。

PC versions of multi-platform games are$ 10 less than console versions to start with, and drop in price earlier also.

游戏PC平台版本的多是10美元不到控制台版本开始，价格下降也较早。

If the reason for the sharp and unexpected drop in price was one-off event, you would probably be better off holding.

如果对价格急剧和意外下降的原因是一次性事件，您可能会更好举行。

Some insiders say the drop in price is because some companies are forsaking quality to sell their products cheaply.

对此，一些业内人士表示，一些制造商放弃质量、廉价抛售，是价格下跌原因。

In this case, you want to display negative values in red to visually represent a drop in price.

在这里，需要将负值用红色显示，以便在视觉上表示价格下跌。

For some car buyers, the big drop in price may easily offset the backsliding.

对一些汽车购买者，价格的大落差很容易抵消（经济）衰退。
