Firstly the basic principle of OFDM and its anti-multi-path-fading are briefly introduced in this paper. Then basing on this point, we researched the basic principle, the coding designing and the algorithm of the signal detection of these MIMO-OFDM systems. At the same time, the performances of STBC-OFDM and SFBC-OFDM were analyzed and simulated under short wave circumstance, and got some useful conclusions, they have certain reference value for more research of short wave communication in future.

Breed of hound dog known for being destructive and causing mischief if left alone and for almost never barking; often described as deerlike because of its grace and speed while hunting; coat is short, smooth, and fine textured and can be red, black and tan, or black (any of which may have white markings as well); large, erect ears are set far forward on head and may be slightly hooded; short tail curls tightly over rump and is sometimes tipped with white; deeply furrowed brow is a distinctive feature of the breed; eyes are oval-shaped and dark hazel or dark brown; adult stands 16 17 in.(41 43 cm) tall at shoulders and weighs 22 24 lbs (10 11 kg); sometimes called Congo dog because the pair that gave rise to the first known Western litter were imported from the Congo into England in 1936; cleans itself fastidiously, much like a cat; tends to have an aloof demeanor; prized by the pharaohs of Egypt as hunting dogs and adopted by the tribes of the Congo much later; called African bush dog by the English because British explorers first found this dog wandering in the African bush.
巴辛吉小猎犬是一种产于非洲大陆的小猎犬品种,以其具有破坏性和孤独时的调皮捣蛋以及几乎从来不吠叫而著名;当它进行捕猎时,因为它的速度和优美的风度而经常被形容成鹿;皮毛短而光滑,有着很好的质感,有红色,黑色,黄褐色(任何颜色中都混有白色的标记);大而坚挺的耳朵距离较远地分布在头部两侧并轻微地往前罩盖;短小的尾巴紧凑地卷曲在臀部上方,部分巴辛吉小猎犬的尾部顶部呈白色;脸部眉部有深深的皱纹也是品种与其他品种的区别;眼睛深褐色或者深棕色呈椭圆形;成年巴辛吉小猎犬站立肩高41—43公分,体重22—24公斤;有时候也被称为刚果狗,因为第一对巴辛吉小猎犬于1936年从刚果引入英国;巴辛吉小猎犬经常一丝不苟的清理自己,有些像猫;具有冷漠的举止;作为猎犬曾受到埃及法老的赞扬,之后为刚果部落所使用;当它首先被英国探险者在非洲灌木丛中发现时被称为非洲灌木狗。

Methods: 1. Experimental laparoscopic liver resection: We selected pigs as experimental models aiming to approach human beings physiological and anatomical condition. After CO2 pneumoperitoneum was established, the ligaments around liver were dissociated. Livers were cut off by the methods such as clamp dissection, microwave tissue coagulator, ultrasound dissector, Ligsure dissection, hand-assisted, short abdominal incision laparoscopy-assisted, and Endo-GIA switcher. The operation time and bleeding volume were compared between different methods of laparoscopic liver resection. The advantages and limitations of different methods were summarized. 2. Clinical laparoscopic liver resection: 15 cases with tumors in segment V of anterior right lobe or segments II, III of left lateral lobe or segment IV of left internal lobe were selected in this study. The liver diseases included hepatocellular cancer, hepatic cavernous hemangioma and hepatic focal nodular hyperplasia. The ligaments around liver were dissociated after CO2 pneumoperitoneum established. Laparoscopic liver resection were carried out by some of the methods combined such as clamp dissection, microwave tissue coagulator, hand-assisted, short abdominal incision laparoscopy-assisted, ultrasound dissector, rotation and suction dissector.

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.
氯代有机物一般都是典型的持久性环境污染物,其中部分氯代有机物还是环境激素类物质,例如,滴滴涕、林丹和六氯苯等,这些氯代有机物在环境中的迁移转化一直是国际环境化学领域的热点、重点课题。氯代有机物进入环境水体后,成为沉积物吸附态有机污染物的重要成分,天然水沉积物经常处于缺氧状态。因此,研究氯代有机物在天然水体沉积物中的缺氧脱氯行为是非常必要的。
