I am not even going to mention that huge 8ft long seat that bolted onto the top tube.

我不是甚至提到，庞大的8英尺长期座位上的螺栓上管。

Foam onto the tubes lengthwise. Of course, I could no longer keep the

上管纵向。当然，我再也无法保持转矩管夹具在地方，因为他们要撷取泡沫，以

Based on the structural model of tracheid from Bolton and Petty,the flow-resistor of tracheidis assumed to consist of four components in series.

设若一个管胞的流阻为Rg，管胞腔的流阻为RL，纹孔系统3部分的流阻分别为RPA、RBT和RMo；又，在某一个纹理方向上管胞纹孔的数目是N，纹孔膜的微孔数目是NM，则管胞在该纹理方向上流阻的数学表达式为

Objective: To explore the effects of uremic serum on proliferation and collagen secretion of human renal tubular epithelial cells.

Remark: Administrators who are dismissed by owner, may apply for admin again when they are available to abide by admin duty, and may be reconverted at once.

注：对于长期没来上管而被室主撤销管理的管理员，可以在有时间上管时候，重新申请，立即恢复。

Based on the comparison between several present schemes controlling DC motor with PWM, a design scheme for drive circuit fit to EPS is presented, in which both low side and high side are N-MOS and high side is either in fully-off or fully-on state while low side is controlled by logic circuit.

在分析电动助力转向系统电机驱动电路性能和可靠性要求的基础上，对比常用的PWM控制直流电机的优缺点，提出了电动助力转向系统驱动电路的设计方案：上、下管均采用N沟道MOS管，上管常通或常闭，下管由PWM逻辑电平控制。

The down tube takes full advantage of the bottom bracket shell's 90mm width, the top and down tubes are pushed right up to the edges of the integrated head tube, and the top tube is fairly broad throughout its length.

在下管充分利用的中轴 shell 的90毫米宽，顶部和下管权推到综合管头部的边缘，而上管是其整个长度相当广泛。

Experimental results show that: bearing capacity of JPP is thirty percent higher than that of cast-in-place pile which has the same length and diameter with JPP. The deformation of JPP is controlled by core pile; axial force distribution of PHC is different with soil-cement; and their axial force ratio in same section is their elastic modulus ratio. Distribution of inner and outer friction resistance is similar; and the inner friction is about 1.62 times of the outer one; it is about the ratio of JPP diameter and PHC diameter. Furthermore, the relation between friction resistance and relative displacement is similarly hyperbolic; and the relation between dip resistance and displacement is also hyperbolic.

试验结果表明，JPP桩与同桩长、同桩经灌注桩相比承载力高30%以上；JPP桩变形由芯桩控制，管桩轴力分布与水泥土轴力分布规律不一致，但同一截面上管桩和水泥土的轴力比值约为其弹性模量的比值；内外摩阻沿桩身的分布规律类似，内摩阻是外摩阻的1.62倍左右，约为JPP桩直径和管桩直径的比值；桩侧摩阻力与桩土相对位移近似双曲线分布，桩端阻力和桩端位移也近似双曲线分布。
