Traditional three phase three legsinverter can provide relative good performance. However it will be ineffectivewhen it is connected to non-linear unbalanced loads which are often used invital occasion such as military, bank, hospital and so on.

传统的三相三桥臂逆变器虽然能提供较大功率，但是由于非线性不平衡负载的普遍存在，而且这些非线性不平衡负载往往出现在非常重要的场合，如：军事、银行、医院等要求电能质量很高的领域，此时传统的三相三桥臂逆变器显得无能为力。

There were also some larva of copepod and macrura in different developmental stages. Brachionus calyciflorus, B.falcatus and Bosmina longirostris appeared in each station.

调查期间各站位均出现的种类有萼花臂尾轮虫、镰状臂尾轮虫（ B.falcatus ）和长额象鼻溞。

Site was detected near the centromere of metacentric chromosome, while the other homologous one had no hybridization signal.

在石蒜染色体上发现9个杂交位点，在1号长臂端部、5号近端部区域和6号长臂近着丝粒区域各有3个位点。

Objective To evaluate the frequency of microdeletions in the long arm of Y chromosome of idiopathic infertile males with azoospermia and oligospermia in Xinjiang province in China and to investigate the difference of Y microdeletion frequencies between two nations.

目的评估新疆地区汉族、维吾尔族不明原因无精子症和严重少精子症男性患者Y染色体长臂微缺失的频率，探讨不同民族间Y染色体长臂微缺失发生率的差异。

In the thesis, a series of novel single and multi-armed oxadiazole bridging ligands and pyridyl-4, 5-imidazole dicarboxylic acid ligands have been synthesized. The coordination chemistry of these novel ligands with transition metal ions was investigated. In addition, two 1, 3, 4-oxadiazole bridging ligands end-capped by chelating Schiff-base coordination sites have been designed and synthesized. The coordination chemistry based on one of the two ligands with metal ions was primarily investigated.

本文报道了一系列新颖的含1， 3， 4-Oxadiazole杂环的单臂及多臂有机配体，研究了它们与过渡金属离子的配位反应化学；合成了吡啶基-4，5-咪唑二羧酸有机配体，研究了它们在水热条件下与过渡金属离子的配位反应化学；另外，还合成了1， 3， 4-Oxadiazloe杂环桥联的双Schiff-base有机配体，初步探讨了其与过渡金属离子的配位反应化学。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。

MAIN OUTCOME MEASURES: The pendular movement route of non-throwing-arm at the stage of final exertion; The correlation between the braking of non-throwing-arm and the trunk at the stage of final exertion.

主要观察指标：①非投掷臂在最后用力中的摆动路线。②最后用力阶段非投掷臂制动和躯干的关系。

The straight portion of the meridian from the heart system goes upward to the lung, then it runs out from the axilla, it goes along the posterior border of the medial aspect of the upper arm behind the Lung Meridian and Pericardium Meridian, it runs downward the medial aspect ot the elblow and descends along the posterior border of the medial aspect of the forearm to the pisiform region proximal to the palm and enters the palm, it follows the medial aspect of the little finger to its tip.

它的直行脉：从心系（即心与它脏相联系的系带）上行至肺，向下出于腑下，沿上臂内侧后缘，走手太阴，手厥阴经之后，下向肘内，沿前臂内侧后缘（灵道、通里、阴郄、神门），到掌后豌豆骨部进入掌内后边，沿小指的桡侧出于末端，接手太阳小肠经。《灵枢·经脉》：是动则病：嗌（1）干，心痛，渴而欲饮，是为臂厥（2）。是主心所生病者：目黄、胁痛，臑臂内后廉痛、厥，掌中热。

Urceolaris and Daphnia pulex were studied under the conditions of laboratory. The toxicity research of trichlorphon showed the median lethal concentration（LC50） of three kind of zooplankton in 24h were 318.5mg/L,315.9mg/L, 3.6μg/L respectively.
