The interdental distance between the mesial groove of the first molars and distal groove of the second molars was measured on the maxillary dental casts. The interdental distances at the end of experimental tooth movement and retention were calculated. The effectuality of retentive appliances was evaluated by comparing the tooth movement distances between the experimental side and control side.

在加力结束后和保持结束后即刻制取上颌石膏模型，测量所有模型的第一磨牙牙合面近中沟与第二磨牙牙合面远中沟的距离，计算加力结束后与保持结束后的距离，比较实验侧与对照侧的牙齿移动距离，评价保持装置的有效性。

At the electron microscopic level, Schwann cells were seen to be located in the endoneurium.

结果 神经损伤后1个月，损伤远端神经中p75NTR和S-100的表达最多，在损伤后6个月时p75NTR降至正常水平，S-100则在损伤后9个月时消失。

The mice inoculated with Coxiella burnetii intrana- sally developed interstitial pneumonia,while the primary pathological changes of mice inoculated intraperitoneally are granulomas in spleen and liver.2.The pathological changes became more severe followed the dosage increasing.3.Coxiella burnetii can be detected in spleen and liver at day 2 after inoculation.the lesion became more and more serious from day 2 to day 12.The characteristic changes were observed at day 7,and recovered at day 14. 4.The reticuloendothelial system are main target of Coxiella burnetii.The pathogen was detected in cytoplasm of monocyte -macrophages of spleen, liver, lung, and endothelioid cells of blood vessel. 5. Coxiella burnetii can be found in macrophages lysosomes by electron microscopy. Most of them are round or rod, and polymorphic shape can also be observed in different size.

结果：1、通过不同感染途径的实验证实，滴鼻感染的小鼠主要表现为间质性肺炎，而腹腔注射感染小鼠则以脾脏、肝脏肉芽肿为主要病变。2、通过不同剂量的感染实验发现，随着感染Q热立克次体剂量的加大，动物病变愈加严重。3、通过感染后不同时间的动态病理学观察发现，在腹腔注射后第2d的脾和肝脏即可发现病原体，主要脏器的病理变化从第2d到第12d逐渐加重，第7d动物的病变最典型，至感染后14d动物的受损器官已开始出现修复性变化。4、 Q热立克次体主要侵害机体的网状内皮系统，在感染小鼠的肝、脾、肺和外周血管单核巨噬细胞以及血管内皮细胞胞浆中查见病原体。5、透射电镜观察可见Q热立克次体主要位于巨噬细胞吞噬溶酶体内，呈多形性，多见圆形和杆状，大小不一。

Firstly, this article in view of the CATIA CLSF, elaborated this software post-processing way, the operating mode of the three principles, and has given the explanation to this software overall constitution; Secondly, after having analysised and researched thoroughly how the CATIA/CAM module creates the APTSOURCE file and its format, the rules of CNC milling machining center MODIMILL 4L, FIDIA PowerXP20system and the coordinate transformation of the machine tool, we programmed the code of CMSPP special post-processing software and compiled the interface based on the dialog box pattern which the fine outward appearance, is easy to operate; Finally, from machining practice, the NC program by the post-processing program can be run in the machining center to machine the part.

首先，本文针对CATIA刀位文件的特点，提出了该软件的后处理方式以及软件运行的三条原则，并对该软件的总体构成作了阐明：其次，本文对CATIA／CAM模块生成的APTSOURCE文件格式、FIDIA PowerXP20数控系统的规则以及MODIMILL 4L铣削加工中心坐标转换数学模型进行了深入的分析与研究，在此基础上用VC++6.0语言编写了CMSPP专用后处理软件的算法代码，并且基于对话框模式编写了外观精美、易于操作的功能界面；最后，通过实例验证表明：开发的后置处理软件所生成的数控加工程序能够在加工中心上运行并能进行有效地加工。

Seven Brachionus species in Lake Jinghu were found, of which Brachionus calycflorus, B. angularis, B.diversicornis and B.forficula were determined as common species due to their higher population densities and occurrence frequency. The population density of both B.calyciflorus and B. angularis reached the peak in February and March and decreased rapidly after April, while that of both B. diversicornis and B. forficula remained high during June-September and decreased sharply after October.

结果表明，镜湖常见的7种臂尾轮虫中，仅萼花臂尾轮虫、角突臂尾轮虫(B.angularis)、裂足臂尾轮虫(B.diversicornis)和剪形臂尾轮虫(B.forficula)的种群密度和出现频率较高；前两者种群密度高峰期均出现在2~3月份，4月份后均较低；后两者种群密度在6~9月份较高，而在10月份后很快下降。

Mmol/L and 385±24. 6 mmol/L. At 3, 7 and 14 days after transplantation, the grafts were removed for a morphological observation under histological studies. In 7d, the macro pathology in control group's renal allograft was packed by gastrocolic omentum thickly, open the package and dissect the kidney, the color was paleness and interstitial edema.

对移植后第3、7、14d移植肾的形态学观察：对照组在移植后7d打开大鼠腹腔，可见移植肾被受体的大网膜包裹，网膜明显增厚，剖开移植肾脏，外观色泽苍白间质水肿明显，呈&大白肾&样改变，对照组动物一般在移植后12d左右死亡，死亡时移植肾组织包裹更加严重，肾脏部分发生液化。

Three of 17 cases developed RON after reirradiation for recurrences and 1 case after three course of radiotherapy. Nine patients developed blindness in one eye and eightsix in both eyes. Of all the 17 cases, 4 cases showed visual field constriction or hemianopia.

结果］ 17例RON中，13例首程放疗后发生，3例在NPC局部复发再程放疗后发生，1例在三程放疗后发现。9例单眼失明，6例双眼失明，4例见视野缺损或偏盲。

The hybrid between Brachymystax lenok and Hueho taimen were not a live in the past 2 years. However, the fertility and eyed rate of BH were significantly higher than that of HH and BB (P.05), while the hatching rate were significantly lower (P.05). The larvae died within 1 to 2 hours after hatching. It was observed that the tail of yolk-sac larve couldn't stretch around the yolk, and there were hyperemia in the middle and posterior segment of the tail. The reason why the hybrid between Brachymystax lenok and Hucho taimen couldn't snrvive might was the karyoplasms of the gametes from Brachymystax lerwk and Hucho taimen by distant hybridization were not compatible.

细鳞鲤×哲罗鱿的杂交经过2年多批次实验均未得到成活杂交子代，但在胚胎发育阶段BH的杂交受精率、发眼率均显著高于双亲自繁对照组(P.05)，但其孵化率显著低于双亲对照组(P.05)，BH杂交子代在破膜后1~2h内即死亡，刚破膜的仔鱼尾干中后段至尾鳍部分盘绕于卵黄囊表面不能伸展，且所有破膜仔鱼的尾干中后段均存在充血点，本研究认为，这种反交［细鳞鲑×哲罗鲑］子代不能成活的原因可能是由远缘杂交受精卵核质不相容所导致。

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

Hours after infusion, the radioactivity accumulation appeared in lung, and it revealed that the infused cells distributed mainly in lung, and some appeared in liver, spleen, kidney and bladder. 6 hours after infusion, the radioactivity in lung diminished compared with that at 3 hours after infusion, and bilateral kidneys imagine appeared intensively. 9 hours after infusion, the radioactivity in lung appeared reduced significantly than that at 3 hours after infusion, and liver imagined increasedly, intestine tract imagine appeared in several rats.

本研究中，静脉移植MSCs后3h，肺脏放射性浓集，移植细胞主要分布在双侧肺部，肝脏、脾脏、肾脏和膀胱分布较少；移植6h后，肺脏放射性较移植3h时减弱，双侧肾脏显像明显增强；移植9h后，肺脏放射性较移植3h时明显减弱，肝脏显像增强，个别大鼠肠道出现显像；移植18h后，此时肺脏显像明显稀疏，肝脏和脾脏显像显著加强。
