The indirect decompression mechanism of the pedicle screw open the fracture vertebral and intervertebral discs ,strain posterior longitudinal ligament and intervertebral discs annulus tibrosus ,and push the bone pieces in the vertebral canal ahead to reduct, this process is Ligamentotaxis ,It is function depends on the completement of posterior longitudinal ligament and intervertebral discs annulus tibrosus.

椎弓根螺钉间接减压机制是通过椎弓根螺钉撑开损伤部椎体与椎间盘，紧张后纵韧带与椎间盘纤维环，将凸入椎管的骨块推向前方而复位，称为韧带整复。

The gas phase oxidative cracking processes of decalin and cyclohexane were investigated by using the quartz tube reactor at atmospheric pressure.

采用石英管反应器，在常压下研究了十氢萘和环己烷的气相氧化裂解过程。

It is found that the modified delaminate model in account of circumferential damage is able to well describe the progressive failure of the tubes subjected to axial compressive loading.

研究表明，基于环向损伤假设的分层断裂模型能更为准确地描述复合材料圆管轴压破坏行为。

The two sections are preferably separated by a spacer section and the tubular graft preferably increases in diameter from the Z-stent section to the hooped section.

两部分优选地由间隔部分分隔，而管状移植物的直径优选地从Z-支架部分到环箍部分增大。

Retrospective analysis of 761 case-times successive color Doppler sonography for 518 renal transplant patients was carried out. six parameters of sonography were used to compare, the CsA-NT hemodynamic changes among the patients with normal function, rejected and hydronephrotic kidney.

摘 要 通过对518例肾移植患者连续761次彩色超声波结果进行了回顾性分析，从6项超声指标中，比较了功能正常的移植肾与排斥、急性肾小管坏死、肾积水和环孢素肾毒性血液动力学变化。

The vascular cambium extends to form a complete ring of meristematic tissue around the stem, the separate vascular bundles being linked by interfascicular cambium.

维管形成层向两侧延伸直至形成一个茎内的分生组织环，各个维管束被束间形成层联系在一起。

The interfascicular cambium and INTRAFASCICULAR CAMBIUM link into a complete cambium cylinder that cuts off secondary xylem tissue to the inside, secondary phloem tissue to the outside, and parenchyma cells both sides.

束间形成层和束中形成层组成一个完整的形成层环。形成层以内为次生木质部，形成层以外是次生韧皮部。薄壁组织细胞形成维管射线。

Additionally, because recovery times are short for procedures such as myringotomy and tubes, circumcision, and inguinal herniorrhaphy, early discharge from the facility is feasible.

恢复时间短的手术如鼓膜切开与置管术，包皮环切术和腹股沟疝修补术早期离开医院都是可行的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
