反转的

Hockney surmises, however, that this convex mirror could be turned around and used as a concave projection mirror: If you were to reverse the silvering , and then turn it round, this would be all the optical equipment you would need for the meticulous and natural-looking detail in the picture.

但霍克尼的猜测是，把这个凸面镜前后反转过来，便能当成可投射的凹面镜来用：「如果你把银涂在凸面镜的反面，并将它反转过来，就变成能做出精细自然画面的道具了。

On the base of roundly analyzing and studying phase relation of stator magnetometive force and rotor one of brushless DC motor,the main purpose of this paper is to analyze thoroughly positive and negative rotation logic layout of sensorless BLDCM,and explains the differences between BLDCM and sensorless BLDCM.

依据无刷直流电动机定转子磁势的相位关系，深入分析无位置传感器无刷直流电动机正反转控制的逻辑编排，并分析了无位置传感器和有位置传感器正、反转控制的不同。

The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger.

结果表明，无论加刻什么类型的横向细沟槽，声压级都大幅升高；速度对声压级的影响程度大于负荷；在3种类型的横向细沟槽中，S形直沟槽噪声较小，且正、反转时声压级差异小；15°斜沟槽声压级较0°与15°交替排列沟槽略高，但0°与15°交替排列沟槽的正转和反转声压级差异较大。关键词：轮胎；轮胎噪声；胎面花纹；横向细沟槽中图分类号：TQ336.1；TB533+。2文献标识码：B文章编号：1006-8171(2009)

Next, in chapter 3, we compare the current densities in inversion region and accumulation region of the RTO oxides with and without ANO-DAC. We found that the leakage current in inversion region is smaller with ANO-DAC compensated, but the current density lowering is slower with time past.

接著，在第三章我们对无阳极氧化与经过阳极氧化补偿后的氧化层做比较，比较在反转区与聚积区的电流密度，发现在阳极氧化补偿后反转区虽有比较小的漏电流，但随著时间经过，电流降低速度比较慢。

The spontaneous emulsifications of sodium dodecylbenzene sulfate, dodecane and three-component water system were simulated on the basis of the reasonable selection of particles and definition of interaction parameters between particles.

通过合理划分流体粒子和定义粒子之间相互作用参数，模拟了十二烷基苯磺酸钠、正十二烷和水三组分体系的自发乳化现象；通过附加固壁条件，模拟了在水动力作用下吸附在岩石表面的油珠发生破裂的非自发乳化过程，以及由于表面活性剂在岩石表面吸附而引起的润湿反转现象，比较了润湿反转前后残余油珠的运动情况。

In the presence of 500nM TTX, 70%M/T cells presented spontaneous activity. 80%M/T cells with spontaneous activity appeared excitory postsynaptic currents , which could be reverted at 20mv, 14%M/T cells appeared inhibitory postsy-naptic currents , which the reverse potential was -90mv. Few presented both EPSCs and IPSCs.

当细胞外液有1uM的河豚毒，70%的M/T细胞有自发活动，其中80%自发活动是兴奋性突触后电流、它的反转电位是20mv.14%的自发活动是抑制性突触后电流，它的反转电位是-90mv，极少数细胞同时有EPSPs和IPSPs。

Fear of the drugs' side effects, widespread skepticism of Western medicine, the reluctance of public figures to say positive things about ARVs, and reverence for traditional healers lead many patients to shun the drugs. Many activists blame the situation on President Thabo Mbeki and his health minister, Manto Tshabalala-Msimang, who, instead of pushing ARVs, have repeatedly emphasized good nutrition and clean water as keys to treating HIV/AIDS.

抗拒的原因很多，比如受不了服药后的副作用、对西药存有心结、公众人物不肯替反转录病毒药物代言推广、甚至传统巫师带头反对等等，许多前线工作者将矛头指向南非总统及卫生署长，后者不但没有主动宣导反转录病毒药物，反而不断强调真正有效治疗方案应该是均衡的营养及乾净的饮用水。

The soft layer of ECC media usually possesseshigh saturation magnetization and also high demagnetizing energy density.

ECC介质由交换耦合的软磁层与硬磁层构成，它是通过软磁层与硬磁层的磁矩在磁化反转过程中的非一致转动来达到降低矫顽力的效果，而无外场时热反转仍为一致转动，因而能保持较高的热稳定性。

The sequence of solutes flowing from the chromatogram would be changed at the inversion point, and so would the entropy condition.

在反转点处，对应的吸附能力相邻的两种溶质的分离顺序发生反转，熵条件也随之改变。

It can also restrict other retroviruses, therefore, suggested as a general defender against retrovirus infection.

TRIM5α也能抑制其它的反转录病毒，因此可能具有广普的抗反转录病毒感染的作用。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
