查询词典 bipolar

The design rules of silicon low temperature bipolar junction transistor are obtained from the simulation results. One way is that the concentrations of emitter and base are decreased on the base of the normal bipolar junction transistor. Another way is that base concentration is higher than that of emitter, i.

The self-centering mechanism design of bipolar endoprosthesis has advocated the use of offset centers of rotation between the inner and outer joint bearing surfaces to generate a self-centering moment on loading to prevent impingement of polyethylene rim and stem neck or cup fixed at wrong place. The design was used popularly, but the function of self-centering mechanism was discussed in very few papers. Three bipolar endoprosthesis were evaluated: UNIQHIP system, UHR system, and AML system.

Recently, bipolar radiofrequency energy has become popular as a method of performing chondroplasty because of accurately treatment to degenerative cartilage and minimal injury to normal cartilage. But the questions of the effects of bipolar RFE to degenerative cartilage, the reaction of chondrocyte and cartilage matrix, the change of the cartilage after the treatment, and the influence to the cartilage degenerative course, were still unknown.

但是双极射频在关节软骨退变治疗中究竟发挥何种作用，治疗区软骨细胞及软骨基质成分反应是怎样的，随着时间的推移软骨表面的变化如何，双极射频对软骨退变的病程有无影响，这些问题都不清楚。

The study of bipolar radiofrequency energy chondropalsty to degenerative articular cartilage of goat We performed bipolar frequency energy chondroplasty to degenerative articular cartilage three months after the first operation.

使用双极射频（Arthrocarc system 2000，射频头是CoVac 50），能级设定为1，对右膝退变的髌骨和股骨内髁软骨进行软骨成形术，左膝进行假手术作为对照。

There are some midst matters in wastewater, for removal of these matters the electrolyze time should exceed 30 min. The experimental results show that the bipolar packed bed cell has best treatment efficiency of phenol wastewater under condition that voltage is 10V, electrolyses time is 30 min, and velocity of flow is 1.03 cm/min.Basic on the study on treating of phenol wastewater, this paper carry on a research on treating of circuitry board film wastewater by bipolar packed bed cell.

本文在以上处理苯酚废水研究的基础上，论文研究了BPBC处理两种不同浓度得脱膜废水，试验结果表明，对于浓度较高的酸化气浮-光酚顿的出水，在外加氧化剂双氧水后，最佳处理工艺：槽电压8V，实际电解时间60min，双氧水的投加量为1倍理论药量，pH值为3，COD的去除率达到60%；在酸化气浮过程采用酸铜废液调节pH值将会降低COD的去除率。

The results showed that the combination of bFGF and BDNF added to 10% and 5% serum OE medium increased the bipolar cell number and percentage, stimulated the process outgrowth of bipolar cells, and decreased the numbers of giant cells and fusiform cells.

结果显示：将bFGF与BDNF的组合分别加到10%和5%血清的OE培养基中，增加了双极细胞的数量和比例，刺激了双极细胞突起的发育，减少了大细胞和梭形细胞。

Depressed patients with bipolar features are both less likely to respond to antidepressants and more likely to have tolerability problems with these drugs, possibly because they elicit hypomanic symptoms such as agitation and sleep disturbance, said Dr. Sharma. What is less known is whether these bipolar features are subtle enough for clinicians to miss them if they are not careful.

Sharma博士指出，有双极特征的忧郁症病患对于抗忧郁药物的反应可能比较不好，而且对这些药物较可能有耐受性的问题，可能是因为这些药物会造成轻躁性症状，例如躁动、睡眠障碍；目前仍不清楚双极性症状的病征是否会使得临床医师忽略这个症状，如果他们不小心的话。
