In conclusion, the load of ischial tuberosities could be effectively mitigated in sitting position when the adjustable soothing chair was used; the adjustable mechanism could make the shape of the back-support match more with the curvature of lumbar spine, so that the touching face of waist toward the chair was increased and then the load of back muscle was decreased.

因此使用可调式抒压座椅时，能在坐姿时有效地减少坐骨粗隆所承受的负荷，其中可调式调整机构能使背垫的形状更符贴於腰椎的曲线以增加腰部接触面积进而减少背部肌肉的负担，并且尽量维持腰椎前凸的曲线，减少造成下背痛的发生率。

If be opposite not carefully,this is meant vein sex is impotent try the cent vein leakage that is aimed at different type uses different operation kind to cannot obtain better curative effect, did not add discriminative land in the past alone ligate carries deep vein on the back to fail to obtain ideal curative effect also is at that time the inevitable result of people understanding superficial.

这就意味着如果不仔细对静脉性阳痿加以分型并针对不同类型的静脉漏采用不同的手术方式便不能取得较好疗效，过去不加区别地单独结扎背深静脉未能取得理想疗效也是当时人们认识浮浅的必然结果。

Tail is well plumed, set on level with the topline and curved gracefully over the back so that the hair of the tail rests on the back.

尾巴：有许多羽毛，尾巴的位置与背线齐平，温和地卷在背后，所以尾巴上的毛发靠在背后。

Results The hEFs were successfully isolated and cultivated from gonadal ridges and dorsal mesenteries of human embryos. They could be passaged beyond the 25th generation. The biologic characteristics of the cells did not change, even in high-passage cells or frozen-thawed cells. The cells expressed prolyl 4-hydroxylase β, but not cytokeratin-4, which was similar to the fibroblasts. The cultured cells expressed bFGF and LIF.

结果：从人胚胎生殖腺嵴和肠背系膜中成功地分离培养出hEFs，该细胞可传25代以上，且经过传代及冻存复苏后生物学特性无改变；hEFs表达脯氨酰4-羟化酶β亚单位，不表达细胞角蛋白4，确定其为成纤维细胞；该成纤维细胞表达bFGF和LIF。

Rick had his arm flung protectively across his wife's back, and was gazing at her through the helmet's bubble-shield.

And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时，底部叶轮将液体逐步上推，待液体进入上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。
