半连续的

Secondly, by using the connection, we prove that the minimal continuous semi-flow is the minimal continuous flow if its time-one map is open, and for any minimal continuous semi-flow, there is an invariant residual set such that the restriction to the set is a minimal continuous flow.

为此，我们首先建立了它与其时间1映射极小集的联系；然后，利用这种联系证明了：若时间1映射为开映射，则它是极小的连续流，并且一般地说来，对任意极小连续半流，存在不变的剩余集，使得它在这不变集上的限制是极小的连续流。

The article makes a comparison among different types of bus, bus transmission signal and several familiar topologies of front-end converters and load-end converters. Finally, the half bridge converter with full-wave rectifier based on the high-frequency parallel-type AC bus bar is chosen as circuit structure and optimized. The working mode under different condition of the circuit is analyzed and a mathematical model is set up under continuous current mode. Simulation result is used as comparison.

通过对比不同类型的母线、母线传输信号以及各种常见的前端变换器拓扑和负载变换器拓扑，确定了基于并联型高频交流母线的半桥变换器加全波整流作为电路拓扑，并优化了电路的结构，分析了基于不同工作状态下的电路结构并建立电流连续模式的数学模型，并与软件仿真结果进行对比。

From 20 degrees above the ring plane, Cassini's wide angle camera shot 75 exposures in succession for this mosaic showing Saturn, its rings, and a few of its moons a day and a half after exact Saturn equinox, when the sun's disk was exactly overhead at the planet's equator.

从20度以上的环平面，卡西尼号的广角镜头，连续75个暴露这个马赛克显示土星环和其卫星一天半的一些具体土星春分后，当太阳的磁盘上，正是开销地球的赤道。

The subacutely aging rats were made by injecting Dgal into the rats' abdominal cavity continuosly. The learning and memory ability of rats in each group were detected with Morris water maze. The monoamine transmitter contents in hypothalamus and hippocampus were detected with HPLCECD.

D半乳糖连续腹腔注射制作亚急性衰老的大鼠模型，采用Morris水迷宫检测各组大鼠的空间学习记忆能力及采用高效液相色谱电化学法检测各组大鼠下丘脑、海马NE，DA，5HT的含量。

Methods The model of subacutely aging rats were made by injecting Dgal into the rats, abdominal cavity continually. After lavaging HSWY, the apoptosis rate and the levels of Fas and FasL mRNA were measured by TUNEL and RTPCR; the expressions of Fas/Fasl protein were detected by SP immunocytochemistry.

采用D半乳糖连续腹腔注射致亚急性衰老大鼠模型，同时以何首乌饮灌胃作为延缓衰老组；造模后应用脱氧核糖核苷酸末端转移酶介导的缺口末端标记法检测各组大鼠卵巢细胞凋亡情况；测定各组Fas和FasL的信使核糖核酸水平；SP免疫组化法检测卵巢细胞Fas和FasL蛋白的表达情况。

Facing these problems, the half-coupled conservation laws of energy for polar continua, conservation law of energy and Hamilton principle for micropolar multifield theories, principle of virtual velocity and dipolar velocity as well as of virtual stress and dipolar stress for solids with microstructure are proposed.

针对这些问题，提出了半耦合型的极性连续统能量守恒定律、微极多场耦合理论能量守恒定律和Hamilton原理与带有微结构的固体理论的虚速度和虚双极速度以及虚应力和虚双极应力原理等。

Methods: One hundred and sixty SD rats were randomly divided into four groups （40 in each group）, and orally given the medicine with doses of 50, 25, or 12.5 g/kg of crude drug, or with bean oil of 0.5％CMC-Na daily for 26 weeks.The physical status （body weight,growth rate and appetite）, hematological parameters, blood biochemistry, blood cotting, organ index, and tissue pathological changes of rats were checked in the 13th week,and 26th week of the administration and in four weeks after the stop of the administration.

160只SD大鼠，随机分为高、中、低剂量组及空白对照组，雌雄各半，每日灌胃1次，连续给药26周，观察大鼠的一般状况、体重、摄食量和给药13、26周及停药后4周大鼠的血液学、血液生化学、凝血功能、脏器系数、解剖学及病理组织学改变的情况。

The victory also lifted the Yankees (90-56) to the best record in baseball, moving them a half-game ahead of the crosstown rival Mets (90-57). A sweep of Sunday's doubleheader combined with a loss by the Blue Jays would give the Yankees the AL East title.

D！ h7 Z B： x S+~9 ^www.wangfans.com 这场胜利使洋基的战绩(90-56)成为全联盟第一领先同乡的大都会(90-57)半场(连续两天败给后段班的海盗队听说是两个同乡讲好一起登基)洋基如果在明天能连胜再加上蓝鸟输球的话就在分区夺标
