没有阻碍的

The study on laser bending-forming is still in starting phase, so the parameters of laser bending-forming (include laser parameter 、 sheet parameter、 property of material etc.) still can't be controlled accurately. It is also a technique difficulty of laser bending-forming and the important impedimental factors to development of the technique that the inscrutability of forming results and the difficulty to select process parameters.

激光弯曲成形的研究还处于起步阶段，关于激光弯曲成形的参数(包括激光参数、板材参数、材料性能等)还没有达到精确控制的程度，同时成形结果难以预测和加工参数难以选定也是激光弯曲成形技术的一个难点，也是阻碍这一技术向前发展的重要因素。

When Ts is 850 ℃,grains are fined and the size of βphase and the distance betweenβphase pasticles are small.The corrosion barrier effect ofβ phase onαphase is enhanced and the iron content does not increase much at this temperature.So the corrosion resistance is improved.The corrosion resistance of AZ70 alloy falls off when Ts is 890 ℃,which attributes to the presence of microporosity,hot cracking and increase of iron content.

过热温度为810 ℃时，热速处理对合金耐腐蚀性能的改善作用并不大；过热温度为850 ℃时，热速处理显著细化了合金晶粒，β相的尺寸和间距变小，β相对α相腐蚀的阻碍作用增加，而且合金中的铁含量并没有提高，从而改善了合金在试验条件下的耐腐蚀性能；过热温度为890 ℃时，组织中存在热裂纹和显微疏松缺陷，合金含铁量显著增高，合金的耐腐蚀性能下降。

If these conditions do not hold—if nobody outside Washington is really paying attention to the substance of the bill, if the true costs of the tax cut are buried in phony accounting and understated by a trillion dollars or so—the majority party can begin every negotiation by asking for 100 percent of what it wants, go on to concede 10 percent, and then accuse any member of the minority party who fails to support this "compromise" of being "obstructionist."

如果这些条件不存在（如果在华府之外，没人关心这些法案的本质；如果虚假的清算掩没了减税政策的真实成本或是少报为10亿美元左右），多数党就可以在提出法案后要求得到100%的支持，在过程中做出10%的让步，接着指责少数党中的任何成员没有对这种"妥协"表示出支持，而成为法案通过的"阻碍者"。

Not only are you slower (even if your rim isn't rubbing against the brakes, its out-of-round profile causes more drag and friction), but the ride is rougher, you have less control, and you could end up on the ground if the wheel folds or a spoke breaks thanks to the pressure of uneven spoke tension.

你不仅会骑的很慢（即使你的车圈没有和刹车发生摩擦，车圈脱离圆轨的摆动也会造成更多的阻碍），而且由于车圈是粗糙的，你将减少对其控制，而由于条幅受到不均等的拉力，你最终将以车圈扭折或条幅断裂为结局。

Luther, contrary to popular myth, did not revolt easily against papal authority and for a long time held to the conviction of a Petrine office charged with the care of souls in the church; but when he became convinced that the vicar of Christ had in fact distorted and obstructed the proclamation of the gospel, he labeled him instead the "antichrist," and that label stuck for centuries.

路德，相反，流行的神话，没有反抗，容易对教皇的权威和相当长的时间举行的信念，一petrine办公室被控以照顾的灵魂在教会里，但，当他成为相信副主教基督已在事实上被扭曲，阻碍了宣布福音，他标示为他而不是" antichrist "，该标签停留数百年。

In this experiment, effects of local electrolytic lesion of bilateral anteventral or posterior or antedorsal hippocampus on learning and memory of dark avoidance behavior in rats were observed respectively. The results show that local lesion of different part of hippocampus more or less block rat's learning and memory of this behovioral pattern, particularly anteventral lesion, but their instinct of light avoidance and liking dark is not influenced.

本实验分别观察了局部电解损伤双侧海马的腹前部、后部和背前部对大白鼠避暗行为的学习和记忆的影响，结果表明：局部损伤海马各部可以不同程度地阻碍这种行为模式的学习和记忆，其中以损伤腹前部最为严重，依次是损伤后部和背前部，但是对大白鼠避光嗜暗的本能没有影响。

The failure of the Doha trade talks has shown that the multilateral system is clogged:It cannot deliver tariff cuts even though the intellectual case for trade is more widely accepted than at any time in recent history —— think of the transformation of once autarkic nations such as Brazil,India and China into successful globalizers.

多哈谈判的失败表明多边体系已是阻碍重重。近代历史上没有一个时期比现在更广泛地接受降低关税这一有益贸易的大智之举。想想看，就连巴西，印度，中国这些经济独立，自给自足的国家都成了全球化的参与者。然而，多哈谈判却未能实现关税的降低。

It was found from the structure-electrochemical studies of myoglobin that (1) electroreduction induces the T→R configuration transition with peak shift in CD spectra and without umbrella conversed effect, which proved that umbrella conversed effect is mainly the cooperation of four subunits in hemoglobin;(2) the mechanism of EC with adsorption of reduction product and parameters have also been obtained.

肌红蛋白的结构-电化学研究中发现：（1）电化学还原诱导了肌红蛋白的T→R构型转化，伴随着CD谱的峰位移，但没有象血红蛋白那样明显伞翻转效应，表明伞翻转效应是多个亚基共同作用的结果；（2）获得肌红蛋白电化学还原的EC机理，并伴随产物吸附的自阻碍过程及其参数。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
