A new scheme based on dq transformation and positive feedback is provided to detect islanding. Based on the new scheme, methods of voltage positive feedback and frequency positive feedback by dq transformation are proposed in this paper.

为了检测孤岛效应，本文提出了基于dq变换和正反馈的新检测策略，基于这个策略，提出了基于dq变换的电压正反馈和频率正反馈两种检测方法。

Lastly, anti-jamming method based on jittering orthogonal codes at different moments is studied, orthogonal codes are searched with the genetic algorithm, and random initial phase is also used in this method, so great anti-jamming performance is gotten, and the performance is testified through the simulation.

提出了基于正交编码捷变的抗干扰方法，使用遗传算法搜索正交编码集，在不同的慢时刻使用相互正交的编码信号，并与随机初相方法相结合，有效地抑制了基于转发的有源干扰。

Only the first parenthesized group in the regular expression will be recognized; if you can't express everything you want that way, you can return multiple regular expressions, each of which contains a parenthesized group to be matched.

只有在正则表达式中的第一个括号组被识别；如果你不能以此方法表达你想要的东西，你可以返回多个正则表达式，其中每个正则表达式都包含一个用于匹配的括号组。

The early magmatic rocks include quartz syenite porphyries , syenite porphyries , striking in near SN direction; the latter ones include biotite syenite porphyries , lamprophyres, striking in near EW direction.

详细讨论了北衙矿区的地质特征，通过对勘探资料的深入研究和野外观察，初步确定，北衙矿区存在两期岩浆活动，早期的石英正长斑岩、正长斑岩等近南北向分布，晚期的黑云正长斑岩、煌斑岩脉等呈近东西向展布。

Integrating out the small parts of the quark and antiquark fields but keeping both the quark and antiquark freedom in QCD, we get an effective Lagrangian which contains quark, antiquark and quark-antiquark mixing terms.

从QCD拉氏量出发，同时保留其中正，反夸克自由度贡献，仅将正，反夸克场中的小分量积分出去而得到一个包含正夸克项，反夸克项及正反夸克耦合项的拉氏量。

As a result, all the successive arisings of bodily and mental processes will present themselves to the consciousness engaged in noticing, as if coming to it of themselves; and mindfulness too seems as if alighting on the processes of itself.

由内观也会生起非常强的正念，由于这种正念的力量，一个接一个生起的心法色法好像自动地呈现在心的视野中而被观照，此时正念好像也自动落于被观照的名色上。

The concents of testosterone and NO of the mouses gavaged with high dosages of Chinese chive extractiong were not significantly more than that of giving middle dosages.This indicated that Chinese chives might be more safe than traditional chinese herbals of sexual improvement function.2、The screening of sexual improvement function chemical substances of Chinese chivesThe crude extract was leached to four phases by petroleum ether, ethyl acetate,n-butanol and water.By doing animal tests to detect the contents of testosterone and NO in serum of mices,the result was showed that the extracts of petroleum ether and n-butanol have sexual improvement function,especial the n-butanol phase.

从小鼠灌喂不同剂量的韭菜提取液试验结果来(来源：ABCa539a5论文网www.abclunwen.com)看，灌胃高剂量的小鼠的睾酮含量和NO含量相对于中剂量来说并不上升，而是保持稳定，因为睾酮含量和NO含量过度上升可能会带来付作用，所以由此可以说明其食用安全性高，副作用小。2、韭菜改善性功能物质的筛选将韭菜粗提物依次通过不同溶剂萃取，分成石油醚、乙酸乙酯、正丁醇和水四个萃取相，通过小鼠灌胃的动物试验，以小鼠血液NO含量和睾酮含量为指标，发现正丁醇和石油醚萃取相中的物质有改善性功能的效果，尤其是正丁醇相效果非常显著。

Compared with traditional wavelets and wavelet packets, COWB and COWP have not only better frequency localization, but also waveshape variation.

并指出这种正交小波基的混合不同于2尺度正交小波基的混合，因为它可以来自于同一正交尺度函数。

You see, it is with the winter winds gently dance, a shake a shake, a-down, which dance bleak winter color, but lacks some passion; it is head down to the earth gently tell, tell forward to winter, the feeling tone in the more helpless do anything for him; it is enjoying a winter rain baptism, baptism, it seems to be more of the fresh and natural, but less in spring and autumn the youthful vigor; it's head still wore winter rain left collections of diamonds, diamond it has become beautiful, but also adds a number of Qichu look.

你看，它正随冬风轻轻的舞蹈，一摇一摇，一上一下，它舞出了冬季凄凉的颜色，但缺少了一些热情；它正低着头向大地轻轻的诉说，诉说着对冬季的感受，语调中多了一丝的无奈；它正享受着冬雨的洗礼，洗礼后的它看上去更加的清新自然，但少了春秋季节的青春活力；它的头上还顶着冬雨留下的颗颗钻石，钻石让它变得美丽动人，但也增添了一些凄楚的神情。

The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.

结果表明：采用正压力线性变化假设所得的切向力分布规律与拉伸实验结果吻合较好；切向力关于拉伸方向呈轴对称分布，从正上方到两侧逐渐增大；当摩擦系数较小时，切向力分布较均匀，但当摩擦系数较大时，切向力从正上方到两侧迅速增大，试样的颈缩和断裂发生在标距段内靠近标距边缘的位置。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
