An algorithm for detecting moving IR point target in complex background is proposed,which is based on the Reverse Phase Feature of Neighborhood of target in difference between neighbor frame images that two positions of the target in the difference image are near and the gray value s of them are close to in absolute value but with inverse sign.

基于运动点目标在邻帧差分图像中所具有的近邻反相特征，即运动点目标的两个位置相邻近、灰度值一正一负，提出一种在复杂背景下，基于红外序列图像的运动点目标检测算法。

Based on geometric optics method, the atmospheric profiles are inverted from the excess phase delays of a COSMIC RO event occurring on June 6, 2007 over Australia.

基于几何光学反演方法，由附加相位延迟序列出发，对2007年6月6日发生在澳大利亚上空的一次COSMIC掩星事件进行了反演。

Using CHAMP observational data samples, the profiles of atmospheric bending, refractivity, pressure, and temperature were retrieved in turn by the series of signal noise ratio.

利用CHAMP卫星的GPS掩星观测资料，通过观测信噪比序列进行了大气弯曲角、大气折射率、大气压、温度剖面的反演计算；并与相位反演结果进行了比较和讨论。

Strain H1 could denitrify under shallow shaking conditions as well as in the initial atmospheric oxygen concentration ranging from 0~21%.

在150 mL的培养液中，连续以2 L/min的速率通气， H1依然能够反硝化，但是更高的通气速率则反硝化停止。16S rDNA序列分析表明，菌株H1与Ralstonia taiwanensis相似性达98%。

In this paper divided the river network into two types: treelike network and annular network,and use time sequence observations on few observation points as the inversion of information, verified use of genetic algorithm inverse of the entire river networks roughness is feasible.

本文将河网分为环状和树状两种不同复杂的情况，把河网中部分观测点的时序列数据作为反演资料，验证了利用遗传算法反演整个河网中所有河段的糙率是可行的。

Contrast source inversion algorithm recasts the inversion problem as a minimization of a cost functional, thus an iterative sequence is formed to reconstruct the contrast sources and contrasts.

对比源反演算法将反演问题转化为求解成本泛函的极小值问题，从而形成重构对比源和对比度的迭代序列。

Used the method of touch down PCR, the ACS2 gene was cloned from DNA of Petunia hybrida. At the same time, its gene sequence DQ090003 was obtained in GenBank, the antisense repetition of ACS2 linked the plasmid pBI-121 by use of one step. In the result, the expression vector having antisense repetition gene was constucted.

利用降落PCR的方法，从矮牵牛DNA中扩增出ACS2基因片段，在GenBank中获得基因序列号为DQ090003；利用一步法将ACS2基因的反义重复与pBI-121质粒连接，构建含该基因的反义重复表达载体。

Due to the sensitivity on and strong attention paid to anti-Utopia theme by British literature, British literature still dominates the category of anti-Utopia novels.

英国文学对反乌托邦主题的敏锐度和强烈的关注，使得在反乌托邦小说的序列中，英国文学依旧占据了主流地位。

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。
