目的 通过对胎头位置异常120例及臀位60例施行气囊助产术研究，可使多数按常规处理应行剖宫产术的胎头位置异常者转化为阴道分娩，还能顺利解决正常体质量之臀位经阴道分娩。

Thus voicing can be more effective in changing the apparent key weight than lead weights.

这个移动的距离，不能够是一个琴弦的间距，因为如此会使得音槌触击琴弦时，仍是在音槌凹陷的位置（译注：在 3 条琴弦的位置，相对应的音槌上也有 3 个凹槽，这是音槌正常触击琴弦的位置）。

The key points of sensorless technology in PMBLDCM are to study a method which can detect rotor position accurately by simply method in whole speed range. After analyzing current sensorless methods of the PMBLDCM, it is found that those methods are successful at middle and high speed, but they often fail to detect rotor position at low speed when the back electromotive force is small or zero.

纵观目前的永磁无刷直流电机的无位置传感器控制方法，比较成熟而可行的方法多集中于电机在中高速区域运行时，能够较准确估计转子位置；电机处于低速、极低速、静止状态时电加热管，因为反电动势幅值较小或者为零，而无法正常工作。

方法1、对20名正常志愿者L3-S1节段进行CT增强+三维重建检查，在三维重建图形上测量横突长度、上下横突间距、椎间孔外椎间隙高度及斜径，观查横突间区域血管走形特点并测量血管内径，然后进行统计分析及评价。2、采用福尔马林固定尸体标本六具，模拟ILIF手术对L3-S1节段进行操作，观察横突间区域重要结构的位置和毗邻关系，并模拟同侧椎弓根钉和单枚椎间融合器的置入过程，探讨该术式存在的问题并改进。3、采用小牛脊柱运动节段标本12具，依序进行不同处理后分为以下7组：⑴正常对照组CG⑵左侧小关节切除+椎间融合器植入组(TLIF⑶TLIF附加同侧椎弓根钉固定组；⑷TLIF附加双侧椎弓根钉固定组；⑸左侧横突间入路椎间融合器植入组ILIF⑹ILIF附加同侧椎弓根钉固定组；⑺ILIF附加双侧椎弓根钉固定组。

The primary result reveals that the normal expression of Clone C103 is profoundly regulated by endogenous auxin in maize root tip, and the expression of Clone C103 maybe has some relationship with statolith in the periphery of central cap.

由此表明玉米根尖内源生长素影响根冠特定基因Clone C103的正常表达；Clone C103在根冠的表达位置推测该基因正常表达可能与中心根冠外周的平衡石有关。

Methods: During the laparoscopy in 150 cases of infertility associated with gynecological diseases, the sero muscle and fimbria of fallopian tube were protected, and the normal fallopian profile, function and the normal anatomy to the ovary were restored.

对 15 0例不孕症合并妇科疾病的患者腹腔镜手术，术中注意保护及处理输卵管浆肌层，伞端及系膜并最大限度恢复输卵管正常形态功能以及与卵巢的正常解剖位置关系；检测术后输卵管通畅情况及追踪术后妊娠情况。

Traffic accident simulation and control technology are simulating the environment and driving process, simulating the operation situation of accident vehicle on the road, making kinematic analysis based on data such as vehicle collision, stop location and collision narks, to determine the normally running line and the speed of vehicle before the accident, presume the collision speed course reversely, use 3D graphics technology to reappearance accidents process , provide scientific theory for the analysis of the cause, make corresponding protect safety technology and strategy.

交通事故模拟与控制技术是对驾驶环境与驾驶行为进行仿真，模拟车辆在道路上发生事故的运行情况，根据车辆碰撞位置和停止位置、车身碰痕等事故现场数据进行运动学分析，确定车辆在事故前正常行驶时的速度和路线，逆向推定碰撞车速及事故过程，应用三维图形技术再现交通事故过程，为分析事故成因，提出相应的交通安全保障技术和策略奠定科学理论依据。

The experimental results show that: DNA of normal gastric mucosa has stable phosphate backbone; Since the peak intensity at 1090 cm^(-1) is lower than that at 1050 cm^(-1), phosphate backbone in DNA of intestinal metaplasia becomes unstable, while the rest spectra peaks are similar to those in normal gastric mucosa; In terms of adenocarcinoma DNA, double peaks at 1090 cm^(-1) whose intensity are higher than 1050 cm^(-1), are observed, which indicates that DNA chain is broken and re-forms a double stabilized phosphate backbones. In addition, peaks at 950 cm^(-1), 1010 cm^(-1), 1100~1600 cm^(-1) also exhibit obvious difference compared with normal gastric mucosa, which shows that deoxyribose and bases are changed due to broken of DNA.

实验结果表明，胃粘膜正常组织DNA中有稳定的磷酸骨架；肠化组织基因组DNA拉曼特征峰在1090 cm^(-1)处谱峰强度低于1050 cm^(-1)处谱峰强度，表明其磷酸骨架变得不稳定，其它位置的谱峰与正常组织相似；腺癌组织基因组DNA拉曼特征峰在1090 cm^(-1)附近出现双峰，其相对于1050 cm^(-1)处谱峰强度更强，提示DNA有可能出现断链并再次形成了稳定的磷酸骨架，在950 cm^(-1)、1010 cm^(-1)、1100~1600 cm^(-1)波段的特征谱峰与正常组织DNA相比变化也较大，说明脱氧核糖和碱基可能由于DNA断链也随之改变。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
