Methods Twenty cases caused by the missal movement of the upper molar aged 10.5～11.5 years were included in this study.

在临床治疗中可以夜间带头帽或颈带配合口外弓，或活动矫治器，也可以使用螺旋弹簧、Ⅱ类牵引、滑动杆或pendulum等［1～5］。

This paper is designed Pull rod injection mould , discussed the basal principle injection mould, especially Double-surface injection mold design , Have introduced the molding handicraft injecting a mould detailedly、equipment Selection、 feed system、Pulling mechanism and molding part design process, As well as demanded an explanation for mold manufacturing technology, Finally draw out the mould picture by CAD software.

本模具毕业设计主要是设计塑料拔杆的注射模具，论述了注射成型的基本原理，主要是了解模具结构中最基本的两板模的设计，熟悉和掌握模具设计的过程，加深对塑料模具的结构和成型过程的认识。详细介绍了注射模具的成型工艺及设备选择、浇注系统、抽芯机构和成型零部件的设计过程，并对模具制造工艺要求做了说明，最后通过CAD软件绘制出模具图。

The recombinant baculovirus was transfected into sf-9 cells by CellFectin reagent. SDS-PAGE and Western-blot analysis showed that the expressed protein was 37ku in molecular mass and exhibited specific immunological activity. These results provide foundation for development of a subunit vaccine with the expressed σC protein against Muscovy duck reovirus infection.

在脂质体介导下将rBacmid-σC转染sf-9昆虫细胞，获得重组杆状病毒rBV-σC；SDS-PAGE和Western-blot分析表明，在sf-9细胞中表达了分子质量约37ku的σC蛋白，该蛋白能与原核表达的σC蛋白免疫小鼠血清发生特异性免疫反应，这为以表达的σC蛋白为抗原的亚单位疫苗的研制奠定了基础。

Has the scientist to do the experiment: When noise intensity when 90 decibels, in retina's rod cell difference radiance's sensitivity starts to drop, distinguishes the time which the weak light responded also to lengthen; When noise when 95 decibels, some 2/5 person mydriasis; When the noise amounts to 115 decibels, the eye reduces 20% to the radiance compatibility.

有科学家做过实验：当噪音强度在90分贝时，视网膜中的视杆细胞区别光亮度的敏感性开始下降，识别弱光反应的时间也延长；当噪音在95分贝时，有五分之二的人瞳孔放大；当噪音达到115分贝时，眼睛对光亮度的适应性降低20%。

To construct the recombinant baculovirus expressing Infectious bursal disease VP2 gene in the chicken primary myoblast cells.

本研究旨在构建在鸡原代骨骼肌细胞中表达IBDV病毒VP2基因的重组杆状病毒。

It shows that when one screw is of opposite phase to the other one, the pure elongational force field is be caused by the vibration, along with the oscillating effect during the course of the surface stretch.

引入右Cauchy-Green张量分析了间隙内的界面拉伸量，发现当两根螺杆反相位振动时，螺棱侧间隙内存在纯拉伸力场，而且界面在拉伸过程中存在着振荡效应。

Compared to the results of AMECO hangar and cover sail of palaestra in Harbin Institute of Technology calculated by classical response spectrum method, the multi-support excitation seismic responses of up chord and down chord of space truss near support are larger, the same to middle chord. These positions always are pivotal and weak, so we should attached enough importance to them.

对AMECO维修机库和哈工大体育场罩篷比较分析了多点输入反应谱法与传统反应谱法计算结果的异同，发现多点输入反应谱法由于考虑了结构支座的影响，网架结构支座部分的上下弦和腹杆的地震响应均比一致输入的地震响应大，这些部位是结构设计中的关键部位或薄弱部位，故需要引起足够的重视。

Based on the analysis of fault feature of teed circuit of parallel transmission line s, a new fault line selecting method is proposed.

针对T型线路中出现同杆双回线的线路结构，提出了判定故障分支的新方法。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
