中杆

For the BM-rice,the sclerenchyma of leaves was shrunken,vascular bundle of leaves was reduced,the strumae of outer epidermis of stem was sparse and the link of phloem of root was loosed and dispersed.

2通过扫描电镜观察，脆性突变水稻的组织结构发生了较大变化：叶片薄壁组织扩张，厚壁组织收缩，维管束数目减少；茎杆外表皮硅质瘤状结构分布稀疏；根中柱韧皮部组织排列稀疏，连接松散。

Had the self-aligning feature not been provided the pin would have been subjected to considerable bending strain with the likelihood of breakage or seizure, or both..

假如没有自动对中的特性，顶杆将承受显著的弯曲应变，具有折断或卡死，或两者同时发生的可能性。

Servomechanism is one of most important subsystem of rocket, and servo valve is the core part of servomechanism. Feedback stick is a precise and low stiffness part and its machining quality and stiffness accuracy determine the accuracy and reliability of servo valve working.

伺服机构是火箭最重要的分系统之一，而伺服阀是伺服机构的核心，反馈杆是伺服阀中的精密低刚度元件，它的加工质量和刚度精度直接影响伺服阀的工作精度和可靠性。

Place handwheel (17) over stem adaptor (12), locating shear pin (28) into the slot on the handwheel.

把手轮(17)装到阀杆接头(12)上，再将剪销(28)放到手轮的槽中。用止动销(18)固定好。

"A circular structure at the base of a ski pole , used to prevent the pole from sinking too deeply into the snow."

在滑雪杆底部的圆形支架，用来防止它陷进雪中太深。

The median velocity was calculated instead of the mean because it is fairly common to find outliers (e.g., breaking a ski pole during the race would make the velocity very low and aberrant).

这里计算的是速度中间值而不是平均值，这是因为中间值较容易发现异常值（例如，在比赛中打破一个滑雪杆会使速度变得异常低）。

This structure effectively compensation between the sleeve and the valve stem of the tolerance zone and in the media of elastic deformation under pressure to resolve the two-way valve in the transmission medium of exchange that exist in the process of sealing problems.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

This structure effectively compensate for the tolerance between the sleeve and the valve stem in the medium zone and the elastic deformation under pressure to solve the two-way valve in the transmission medium of exchange that exist in the process of sealing problems.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

This structure effectively compensate for tolerance between the sleeve and the valve stem in the medium band and elastic deformation under pressure to solve the two-way valve in the process of exchange of the medium transport sealing problems exist.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

This structure effectively compensate for tolerance between the sleeve and the valve body and valve stem in the medium with the elastic deformation under pressure to solve the two-way valve in the transmission medium interchangeable sealing problems existing in the process.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
