长效

The quality problem of resistance reducing material and its misemploy may be existed. The resistivity of resistance reducing material, the rate of steel corrosion, The stability of resistance reducing material and available time are considered.

因此就降阻剂的选择、使用提出了应综合考虑降阻剂自身电阻率、对钢接地体的腐蚀率、对环境有无污染和降阻剂的稳定性和长效性等因素，通过技术经济分析有效长期稳定地发挥降阻剂的降阻效果，减少对接地装置的腐蚀。

Instead, as in all areas of medicine, physicians need to tailor therapy to patients' specific needs. For ADHD patients who have a history of substance abuse, for example, the treating psychiatrist may want to start treatment with a nonstimulant therapy. If the treatment is not adequate, the second choice would be a long-acting stimulant coupled with rigorous monitoring."Because the stimulants used to treat ADHD are controlled substances, there is built-in monitoring," Dr. Alder said."However, we can watch such patients with extra care for warning signs such as early refills."

另外，Alder医师表示，所有的治疗都一样，医师们必须要对患者的特定需求，量身订制一套治疗法；对於有药物滥用纪录的ADHD患者，举例而言，医师们可以先使用非兴奋剂作治疗，若不合适，第二个选择就是长效型的兴奋剂，再辅以密集的监控；因为用以治疗ADHD的性奋剂都属於管制药物，所以都会有著必要的监控要求；无论如何，我们还是可以从患者的一些徵兆看出，如提早作药物补充等迹象。

Women with polycystic ovarium syndrome who had failed to conceive on treat- ment with conventional IVF-ET protocol or during six ovulatory cycle on gonadotropin un- derwent 26 cycles of IVF-ET by conbined long-acting gonadotropin-releasing hormone ago- nist and gonadotropin.

在体外受精－胚胎移植周期中，应用长效促性腺激素释放激素激动剂（go－nadotrophinreleasinghormoneagonist，GnRH－a）合用促性腺激素（gonadotrophin，Gn）治疗26例顽固性多囊卵巢综合征患者并与其中19例前次常规IVF－ET方案治疗的结果相比较。

Hepatitis C virus infection, a leading cause of end-stage liver disease such as cirrhosis or hepatocellular carcinoma. Although therapy with peginterferon and ribavirin will achieve at least a 50% chance of sustained virological response, individual response rate can be further optimized in order to avoid overtreatment in some individuals and undertreatment in others.

C型肝炎病毒感染是一导致肝硬化或肝癌的主因，虽然长效型干扰素和雷巴威林合并治疗可达至少50％的持续病毒反应（sustained virological response， SVR），但为了避免对一些个人和治疗不足的病人过度治疗，使用个人化反应率可使治疗更有效进行。

We selected wuli lake, seriously polluted lake, and used long-term laboratory sludge-dredging method to compare the difference of dredged zone and undredged zone, we conducted sludge incubated experiment of two depth of dredging to analyze the difference of nutrient''s release. We investigated the budge of phosphorus monthly and monitored the concentration of phosphorus of the water simultaneously, and analysised the change of the content of phosphorus of water body and further studied the effect of sludge-dredging on the content of phosphorus in water body.

本研究以污染严重的太湖五里湖为研究对象，对室内长效模拟和疏浚区/非疏浚区比较，进行了两种不同模拟疏浚深度的底泥培养实验，同时对疏浚后环五里湖河道进行了磷出入湖量和湖面磷含量同步调查分析，分析底泥疏浚前后水体磷含量变化，结合逐月出入湖量的初步分析，研究疏浚对湖水中磷含量的影响。
