多次结果的

In some important cases, if the experiment is repeated many times, the variations in the results are found to be distributed according to a particular mathematical law –the normal error law.

在一些重要的情形中，如果多次重复一个实验，会发现其结果的变化按照某个特定的数学法则——正态误差法则分布。

结果：产科失血性休克的发生率为0.65%，胎盘因素是失血性休克的主要原因；主要的危险因素是多次妊娠和流产、院外分娩及重度子痫前期。产科失血性休克导致的子宫切除率为17.6%。

Results of XRD,SEM,and UV-Vis indicated that ZnS nanocrystals can grow in and fill in the void of opal template,and SiO2 microspheres of templates are dissolved so as to form some three dimensional ordered porous structure and to form the inverse opal ZnS photonic crystals. Compared with opal templates,ZnS-opal and inverse opal ZnS photonic crystals assembled with SiO2 spheres in the same diameter show good optical properties and exhibited photonic band gap. The photonic band gap position of inverse opal ZnS moves towards UV area compared with opal and ZnS-opal.

结果表明：溶剂热法多次充填可使ZnS纳米晶在模板密堆积形成的空隙中均匀成核；经过酸处理的ZnS-opal中SiO2微球溶解、坍塌，形成蜂窝状三维有序介孔和反opal结构ZnS基光子晶体；相同粒径SiO2微球组装的opal模板、ZnS-opal以及反opal结构ZnS光子晶体均表现出光子带隙特性，但反opal结构ZnS光子晶体带隙位置相比前两者发生了蓝移。

Through trial and error, piron mastered the grapefruit tree rings, cutting method to technical training for orchard, on-the-spot guidance two agricultural enterprises and farmers cut part adopts loop technique, make one year earlier results, grapefruit, fruit-set rate increase production, realizing the early, Summarizes the grapefruit organic methods, fully in the stable yield, improve the quality of grapefruit.

Methods the diagnosis situation of 19 cases of cryptococcal meningitis who have been confirmed from 1980 to 2004 are analysed.results there are 17 misdiagnosis cases in 19 patients, of which 7 cases are tubercular meningitis,3 are viral meningitis,2 are brain tumor,1 is cerebral edema,1 is arachnoiditis of brain and 2 are others.conclusion misdiagnosis can be discreased by promoting learning about cryptococcal meningitis, examining the doubtful patients' csf frequantly and another examinations.

对本院1980—2004年确诊的19例新生隐球菌脑膜炎病人的诊断情况进行回顾分析。结果 19例确诊前有17例被误诊，其中误诊为结核性脑膜炎7例，脑肿瘤2例，病毒性脑膜炎3例，脑水肿1例，脑蛛网膜炎1例，红斑狼疮脑病1例，其他2例。结论提高对新生隐球菌脑膜炎的认识，对可疑病人多次做脑脊液墨汁涂片检查，或其他检查，可减少误诊。
