The distribution pattern of mGnRH in the brain during regressed stage was similar to that during recrudescing stage.

退化期和再发育期蛙脑中mGnRH的分布规律基本相同：即端脑-嗅球、视前-交叉区、下丘脑-正中隆起的mGnRH含量彼此相近；而上丘脑-中脑及小脑-延脑的mGnRH含量为0。

All rabbits were buying from the animal center of NanFang hospital. 2.2 The development of models A certain quantity of fresh tumor tissue was obtained from the tumor-bearing rabbit and was skived to little pieces.

模型兔麻醉后腹正中切口，打开腹腔后取出肝脏，用巩膜剪在肝表面的三个不同部位形成约2mm×2mm大小的腔隙，再将3块1mm~3的肿瘤组织块放入腔隙内，2～3周后VX_2肉瘤肝脏转移瘤模型建成。

Right at the center of this evil plain there yawns a very wide, deep well, whose structure

METHODS: A total of 20 patients with congenital meso immaturity cleft palate, aged 2-12 years, were randomly and evenly divided into control and bone grafting groups. Orthodox simplex two-flap operation was used to repair cleft palate in the control group, and two-flaps operation was adopt to repair soft tissue meanwhile implant OAM to repair bone defects in cleft hard palate in bone grafting group.

随机选取20例年龄在2~12岁的先天性正中Ⅱ度腭裂患者，随机平均分成对照组和植骨组，对照组采用常规的单纯两瓣法修复腭部软组织缺损；植骨组采用两瓣法修复腭部软组织缺损的同时，植入骨诱导活性材料修复硬腭骨组织缺损。

Now, TH-ASSS has realized ASM1 and 1-D SST Model and reserved good interface for other models. This paper focuses on theory and method of model application in practice. It adopt day-period curve to simulate the variation of influent, pollutant distrubution's normal status and average-HRT to simulate the influence of hydraulic delay in practical system.

本研究重点分析模拟系统与实际系统结合的理论和方法问题，采用进水日周期性变化曲线来模拟实际进水的动态变化，结合污染物排放呈正态分布和动态平均HRT方法模拟水力延迟对模拟结果的影响，将呼吸法测量直接用于参数估计和模型校正中，使模拟系统能够很好地符合实际系统。

Posterior screw-and-rod-based instrumented systems have been shown to provide greater biomechanical stability than anterior constructs by taking advantage of the stronger fixation offered by the lateral masses or pedicles, as well as the greater distance of the fixation from the midsagittal plane.

后路钉棒装置系统与前路装置相比，由于使用了牢固的侧块螺钉或椎弓根螺钉，以及在正中矢状面上有更长的固定距离，因此可以提供更好的生物力学稳定性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
