Proposes the following conclusion according to the research: 1. In the seven major subjects of the health and physical education, besides the third major subject "the movement skill", other six major subjects all has the competency standards or the text content, can be direct or indirectly carry on with the media literacy five big cores concept links, two extremely suitably carries on intergrades the study.

根据研究结果提出以下结论：一、健体领域的七个主题轴中，除了第三主题轴「运动技能」之外，其余六个主题轴皆有能力指标或课文内容，能直接或间接与媒体素养的五大核心概念进行连结，两者十分适合进行融入教学。

Up till now, the main pump types used in CPB are roller pump and centrifugal pump, but these two kinds of pump both have their own disadvantages. When roller pump is used, the blood cells will be destroyed severely and when the pipeline is kinked, air will be transported into body or the conduit will be broken. The function of centrifugal pump is better than that of roller pump, but now, this kind of pumps are all designed for adults, and when the flow rate is low, the function of protecting the blood is not significant.

目前，滚轴泵和离心泵是心肺转流中的常用泵型，但是滚轴泵对血液有形成分的破坏较严重，而且有引起泵管的崩脱和大量气体泵入体内的危险性；离心泵虽然在性能上优于滚轴泵，但目前的离心泵大都是为成人设计的，而且在低流量时在血液破坏方面的优点不明显，此外它们还有一个共同的缺点就是预充量均大，因此两者都不适合在幼婴儿体外循环中应用。

The transition zone shape is oblique step formed with knifing stage of side wedge. It was analyzed in different knuckle angle by FEM simulation and rolling test. The rule of knuckle angle value influence on smooth levels of surface in forming the equal diameter axis with MCWR was obtained.

楔横轧多楔成形光轴类零件时，内外楔之间轧件的过渡段形状为由外楔楔入段轧制而成的斜台阶，通过有限元模拟和轧制实验，对不同过渡角下多楔轧制光轴表面光滑程度进行分析，得到过渡角对楔横轧多楔轧制光轴表面光滑程度影响规律。

The aerostatic bearing levitates the actuating rod with four radial air inlets on each side. The frictionless aerostatic guide can improve the actuating rod is electromagnetically driven by a fixed solenoid and a actuating solenoid. Through adjusting the axial position of the actuating solenoid, the actuating stroke can be fine regulated.

双列径向供气之气静压轴承提供致动轴作径向的支撑，其低摩擦之特性有助於提升定位精度，致动轴两端外侧设有固定线圈与致动线圈，调整致动线圈轴向位置可以改变致动器最大行动范围。

One point is the tail portion of an axial flange swaged into a groove in the rack, and a second part of the same axial flange has a groove for retaining a locking ring in a second groove in the rack.

一个连接点就是一个轴向凸缘的后部，该轴向凸缘被锻压到齿条的一个沟槽内，该轴向凸缘的第二部分设置有一个沟槽，该沟槽用于将锁紧环保持在齿条上的一个第二沟槽内。

As above three condition can't be assure simultaneity,then Imput shaft and output shaft can't do instantaneous synchronization ,and no synchronization become more obvious along with fold angle of shaft's increase.

当上述三条件不能同时保证时，则输入轴和输出轴不能瞬时同步，随着轴折角的增大，不同步愈加明显。

The meshing of FG drives with misalignment, which includes shaft angle error, shaft crossing error and axial shift error, is analyzed by using the continuous tangency of pinion and FG to obtain the equations of tooth contact analysis, and visualizing contact path, and studying the effect of errors on the shift of it. A computational procedure of tooth contact is developed in this paper.

在具有安装误差的面齿轮传动的啮合分析中，建立了在有轴交角误差、轴交错误差和轴向偏移误差情况下的齿面接触轨迹所满足的方程，提出了一种求解接触点参数的策略；对齿面接触轨迹进行了可视化；分析了各类误差对齿在接触轨迹的影响。

Low concentration ryanodine can mimic BDNF to induce growth cone attraction and high dose ryanodine gradient is repulsive to the growth cone.

ryanodine 可以模拟 BDNF 的吸引作用。为进一步研究 Rho GTPases 在轴突转向中的作用，我们将 Cdc42及 RhoA 的显性失活突变基因(dominant negative， DN)及组成性激活突变基因（ constitutively active， CA ）注射到爪蟾胚胎2-4细胞期的一个细胞中，使它们在胚胎神经元中表达，并观察这些突变基因对 BDNF ， LPA ， ryonodine 诱导的轴突转向的不同影响，从而推测 Rho GTPases 是否直接参与并介导轴突导向。

公司的主导产品有：各种汽车半轴、摆臂、连杆、曲轴、调整臂、摇臂、球壳、十字轴、转向节、半轴突缘、万向节叉、焊接叉、滑动叉等种类数百种规格的模锻精品。

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).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
