中原油田深井大井眼段钻井液工艺

濮深8井是中原油田在西部洼陷南部寻找接替储量的一口重点深探井,也是中原油田第一口井深达6000m的超深井。分析了濮深8井钻井液的配备及维护和处理技术,得出深井大井眼段钻井液工艺技术存在以下问题:井眼大,钻井液量及钻屑量多,处理时间长,处理剂用量多,处理频繁;返速低使钻井液清洗井眼的能力减弱;井下温度高使处理剂的作用明显降低,二氧化碳的侵入使钻井液性能变差。钻井液维护处理的较好方法是定时、定量补充处理剂胶液。固相控制是深井大井眼段钻井液工艺中的关键问题,必须配套并且有效地使用固控设备,以维护好钻井液性能。

Effects of lacidipine on serum oxygen free radicals and fasting levels of insulin in patients with essential hypertension

Thirty patients with mild to moderate essential hypertension had received four weeks treatment with Lacidipine and serum lipid peroxide (LPO), superoxide dismutase (SOD) and insulin levels were measured before and after treatment. The results showed: (1) there were decreased in SOD activity and increased Lpo content the patients group (P < 0.01); (2) after treated with Lacidipine, the SOD acitvity increased and Lpo content decreased (P < 0.01); (3) Lacidipine had obvious antihypertensive effect with no significant changes in heart rate; (4) Lacidipine had no significant effects on insulin, blood glucose and lipids. The results suggest that lacidipine is a safe and effective antihypertensive agent and can improve the metabolic balances in free radical system.

Dynamic lithium-ion battery model for system simulation

Presents here a complete dynamic model of a lithium ion battery that is suitable for virtual-prototyping of portable battery-powered systems. The model accounts for nonlinear equilibrium potentials, rate- and temperature-dependencies, thermal effects and response to transient power demand. The model is based on publicly available data such as the manufacturers' data sheets. The Sony US18650 is used as an example. The model output agrees both with manufacturer's data and with experimental results. The model can be easily modified to fit data from different batteries and can be extended for wide dynamic ranges of different temperatures and current rates.     

牙鲆淋巴囊肿病的PCR诊断方法研究

以中国养殖牙鲆 (Paralichthysolivaceus)淋巴囊肿病毒 (Lymphocystisdiseasevirus,LCDVcn)主要衣壳蛋白 (majorcapsidprotein ,MCP)基因的中间保守序列为目标基因 ,设计了一对特异性引物。该引物可扩增出 172bp的病毒DNA片段 ,其最小DNA检出量为 0 0 183ng。用PCR法从人工感染淋巴囊肿病毒 3天的牙鲆血、鳃、肝、脾、肠、胃及自然发病牙鲆的肿瘤中 ,分别检测到了LCDV的存在。本实验结果证明 ,PCR法对于早期检测LCDV是十分有效的。
