By superfusion of ET-1, the hypoxiainduced decrease in RPF was remarkably potentiated (from 136±9 to 48±27 bpm) and the occurrence of pacemaker arrest was shifted to 20±6 min.

在缺氧的条件下持续灌流ET-1（1 nmol／L）20 min时，可显著加重缺氧所致的RPF降低，使起搏细胞的RPF由对照的136±9 bpm降至48±27 bpm（p.01），起搏细胞的停跳时间前移至20±6 min。

However, caution must be exercised to avoid extremely close throttling when pressure drop exceeds 20%.

但是，必须注意的是避免在压降超过20%的情况下进行极端关闭节流。

Oneself walk in the park, is the prospects of an atmosphere of desolation everywhere, the night be quiet pole, the light be dreary, in the breeze curl up sand dust, lightly of candlelight tinily jump about, seem to be so infinitesimal, weak, the parasol tree of street both sides be also withered Huang, the leaf float to fall in succession on the ground, trample on the very thick and withered leaf and feel matchless soft, again rise hope a tree, not from get send out 1 to draw a deep sigh!

春、夏转眼过去了，随之而来的是秋天。晚秋傍晚时分，不再特别耀眼的太阳西下，夜幕降临了。自己走在公园内，到处是一片凄凉的景象，夜静极了，灯光黯淡，在卷起沙尘的风中，轻轻的烛光微微地跳动，显得那么渺小、脆弱，街道两旁的梧桐树也枯黄了，叶子纷纷飘落在地上，踩在厚厚的枯叶上，感到无比柔软，再抬头望树，不由得发出一声长叹！

Worn surface morphology was examined with scanning electron microscopy, and wear volume was measured with a Talysurf 5P-120 topographer. Results show that CNTs, in mass concentration of 0.01%~0.1%, can greatly improve the antiwear ability of lubricating oil. With addition of CNTs, the maximum reduction of wear rate is about 57%, and scratches on the worn surfaces become slighter and more uniform. The maximum decrease of friction coefficient is about 15% with 0.025% CNTs additive at the load of 300 N. The antiwear mechanism has been discussed.

结果表明：碳纳米管作为润滑油添加剂表现出优良的抗磨性能，在质量分数仅为0.0125%～0.1000%时，润滑油的抗磨性能显著提高；在质量分数约为0.0500%时其抗磨效果最佳，磨损率降低幅值达57%；在较高载荷下，添加0.0250%的碳纳米管能够使其摩擦系数减小约15%，但随着碳纳米管质量分数的增加，摩擦系数迅速提高；含碳纳米管润滑油的磨斑表面平整，划痕较细且分布均匀。

The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.

研究表明：桉树不同家系间木材物理力学性质和化学组成存在差异；粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异，株间、株内木材材色存在变异；桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异，在同一家系或同一无性系中，株间和株内也存在着相同的变化规律；桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关，侵填体含物越丰富，纹孔附物越多，桉材越容易皱缩；最大瞬间皱缩是能产生更大干燥降等的临界点，在制定干燥工艺时，必须在最大瞬间皱缩发生时，采用温和条件，使已产生最大瞬间皱缩的细胞尽可能多的恢复，尤其不能使其产生永久变定；在常温条件下，影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量；而对于瞬间皱缩和最大瞬间皱缩，几乎所有细胞都参与它们的形成过程；对于易皱缩的桉树木材，间歇干燥是最有前途的干燥方法。
