查询词典 method of difference

The equations of the towed cable motion are based on Ablow and Schechter model and six degree-freedom ordinary differential equations are used in the analysis of the motion of a towed body. The partial differential equations are discretized by finite difference method and the transient values of towed body depth and cable tension are computed by Newton Iteration when the heave compensation system performs and the length of the cable varies.

Therapeutic effect in both groups was observed 7,14 days later.results there was no significant difference in clinical effective rate, healing state of the ulcer and blood sugar index between two groups (p＞0.05).the treatment group was superior to control group in amelioration of acroanesthesia, pain, skin temperature,skin color,a/b index (p＜0.05).the effect of improving the pulse of dorsal artery of foot in both groups was not certain.the patients in both groups were well tolerant,except for part of patients with adverse reactions of mild or moderate degree.conclusion the clinical efficacy and safety of clearing heat and removing dampness method is similar to that of routine administration of antibiotics in treating diabetic foot infection.the former is superior to antibiotics in improving clinical symptoms.

结果 2组临床有效率、溃疡愈合状况、血糖指标等比较差异无显著意义(p＞0.05)。清热利湿药物联合抗生素在改善糖尿病足麻木、疼痛、皮温、皮色、踝/肱指数等方面优于单用抗生素(p＜0.05)。2组治疗前后足背动脉搏动方面疗效不确切。除了部分轻、中度患者病情波动外，治疗期间均有良好的耐受。结论在治疗糖尿病足感染方面，清热利湿方与通常应用的抗生素疗效相近，在改善症状方面优于抗生素。

By using spectrophotometry method determinated the anthocyanindin and chlorophyll content in different parts of Prunus wilsonii leaves,results showed that,as time changes,anthocyanins content in different parts of the leaves showed a low-high-low change in trend,the analysis of variance,the difference is not significant,relations between anthocyanidin content in Prunus wilsonii leaves and the position of health was not obvious,anthocyanindin content in the same part are far greater than chlorophyll content,...

用分光光度法对紫叶稠李叶片不同部位的花青素和叶绿素进行了测定，结果表明，随着时间的变化，不同部位叶片的花青素均呈现低-高-低的变化趋势，经方差分析，差异性不显著，说明紫叶稠李叶片花青素含量跟着生的部位关系不明显；同一部位的花青素含量远远大于叶绿素含量，这也是紫叶稠李叶片在整个生长季呈现紫红色的原因。

Motheds: to select 336 lomars with pulposis or apicitis from the aged and to devide them into two groups. in group the control group,the illed teeth were given only the root canal therapy. in group the experimental group, according to the difference of every root canal, the unobstructed root canals were treated by root canal therapy. while the obstructed ones were given the root canal resinifying, use two kinds of therapy method together to molais' pathological changes.then their curative effects were observed after two year.
