查询词典 higher

Compared with rare-earths and their alloys, the perovskite-type manganese oxides exhibit higher chemical stability, higher resistivity that favors a lower value of eddy current loss and lower cost, and would be more suitable candidates for magnetic refrigerants at high temperature, especially the potential for application near room temperature.

与稀土以及稀土-过渡金属的合金比较，钙钛矿锰氧化物具有较高的电阻率有利于降低涡流损耗，以及较低的价格，因而这类材料有可能是高温，特别是室温磁制冷的较好候选者。

Results: For CRF rats which made by fed with feedingstuff contains 0.75% of adenine for 4 weeks, the weight of model control group rats were lighter than that of Yi Shen Granule groups rats. The water wastage of Yi Shen Granule groups rats were less than that of model control group rats. Compared urine volume, the ejectable quantity of Na, K, Cl and proteinuria in 12 hours , the data of Yi Shen Granule groups rats were less than that of model control rats. The specific gravity of Yi Shen Granule groups rats was higher than that of model control rats. The numerical value of RBC, HGB, HCT, MCV, MCH in model control group was lower than that in Yi Shen Granule groups. The content of BUN and Cre in serum of model control groups rats were higher than that of Yi Shen Granule groups. The results of excretion test of phenolsulfonphthalein showed that the RPF of Yi Shen Granule groups rats was larger than that of model control group rats.

结果： 益肾颗粒可以使0.75%腺嘌呤饲喂法致大鼠慢性肾衰模型动物体重增长加快；给药后观察，给药组动物饮水量较少，12小时尿量、12小时钠、氯、尿蛋白排泄总量均显著低于模型组动物，尿液比重值较大；模型组动物的RBC、HGB、HCT、MCV、MCH等指标的数值较给药组动物的数值小；给药组动物血清中BUN和Cre的含量较低；给药组动物酚红排泄率均高于模型组动物；给药30天，处死各组动物，尸解观察，模型对照组动物肾脏呈灰白色，各给药组动物肾脏表面均出现不同程度的红、白相兼的颗粒状纹理，各组动物肾脏均肿大，切面可见不同程度的腺嘌呤结晶沉积。

In this paper several problems in the elementary geometry, which seem simple but in fact need thorough analysis, are taken for example to explain how to make use of the knowledge learnt from the higher meths so as to study the problems concerning the eductional reform of the higher maths, which should lead to our consideration.

本文以初等几何中一些看似粗浅实际上需要深入分析的问题为例来说明，如何利用高等数学学到的知识，来研究中学数学等有关高师数学教育改革应引起大家思考的几个问题。

The expression level of tim gene in 25LL is markedless higher than 15DD and 20LD in the early incubation stage(7 days before), but it is obviously higher than 20LD and 15DD conditions in the late.To further invesgate the per and tim expression in different moment every day of the sensitive period(7d,8d,9d) during the process of embryogeny,the expression of tim gene was very low and the per and tim expression did not have obvious rhythmicity under 15DD condition.

进一步调查家蚕胚胎对环境敏感时期(7d-9d)per和tim基因的昼夜表达节律，在15DD条件下，tim基因表达量一直很低，tim基因和per基因的表达量都没有明显的节律性变化；而25LL和20LD条件下，两基因在一日中不同时刻的表达具有明显的节律性，表达量也较高。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
