低能

In the present study, the autotetraploid rice IR36-4X was treated with ion implantation technique by nitrogen ion beams and a polyembryonic seedling mutant (named as the IR36-Shuang) was identified in M2 generation. The mutant line was systematically investigated about the location of seedling in polyembryonic seedling, and the cytological initiation of the additional embryo in the 1R36-Shuang was observed and determined.

以低能氮离子束为诱变源，通过对同源四倍体水稻品系&IR36-4X&进行离子注入后在其第2代群体内筛选得到了1株具有多胚苗性状特征的突变株（IR36-双），对该突变株后代的多胚苗形态特征及其多胚来源进行了研究。

The tacit admission of the DRDO's inability must not be limited to the mis sile programme alone; a review of all projects under its aegis is needed for a reality check and course correction.

DRDO显而易见的低能并不仅仅表现在导弹项目上；在其名下的全部项目需要更进一步的核查和清算。DRDO的错误根源主要在于对科研成果、重点、以及缺乏合理安排进行追究的缺失。

The screening of high tannase producer and mutagenic effects of Aspergillus niger 9701 with low N + ions implantation were studied.

研究了单宁酸酶高产菌株的选育以及低能N+离子注入黑曲霉 970 1 (Aspergillusniger 970 1 )的诱变效应。

Dimethoxy-thiophen-2-yl-benzo[1,2,5]thiadiazole(PC-co-DMOTB). Electrochemical and photophysical studies reveal band gaps of 1.90eV for PF-co-DMOTB and 1.82eV for PC-co-DMOTB, which could effectively harvest broader solar spectrum.

电化学及光学上测量判断其能隙与能阶，PF-co-DMOTB 其能隙为1.90eV ，PC-co-DMOTB则为1.82eV，其低能隙及施体受体交替之特性使其对光谱有较广之吸收。

Result The nested PCR assay was specific and there is no cross-reaction with other parasites, such as Eimeria spp., Cryptosporidium spp., Giardia sp., Toxoplasma sp., Trichuris sp. and cattle ciliate. The assay was able to detect as low as 2.85 × 10^(-2) fg of control positive DNA. The results of detection of clinical samples revealed that the assay was coinciding with microscopic examination.

该套式PCR能特异性地扩增出牛源环孢子虫基因组DNA中相应片段，与艾美耳球虫、隐孢子虫、贾第虫等10种相关原虫基因组DNA无交叉反应；最低能检测到2.85×10^(-2)fg的阳性参照DNA；对临床样品检测结果表明PCR技术检查阳性者显微镜检查都为阳性。

From little nitpicks (pre-fight loading screens stutter in that "this game wasn't ready" way; unintuitive practice-mode menus are a pain to navigate) to glaring issues (single-player difficulty levels all feature moronic A.I.; you can't exit the online spectator mode ), KoF12 looks and plays like a game that got kicked out the door just in time to ride the coattails of its competitors' wild popularity.

从细微的瑕疵（开战前loading画面拖曳得感觉像半成品，非常不直观的训练菜单对新手是一种折磨）到刺眼的毛病（单人模式下困难难度依然面对的是极度低能的ai；网战的观战模式无法退出），kof12玩过后就让人感觉就是那种游戏随时会被成功赢得市场已经在树荫下乘凉的竞争对手踢出门外。

Centrifugal chiller, the main equipment of DEG system, has operated unstably in a state of low load /low energy since 2000, which brought some effects to NI ventilation systems, and was a hidden trouble for Nuclear Power Unit.

DEG系统主设备――离心式冷水机组自2000年投运以来，一直存在低负荷和低能头运行工况下机组运行不稳定的状况，给核岛通风系统的正常温度调节造成一定影响，也是核电机组正常稳定运行的一个隐患。

We have epitaxially grown ultrathin Pb and Co films on the Cu(111)surface bymolecular beam exitaxialgrowth technique,and studied in detail the growthand surface alloying of submonolayer Pb on Cu(111),the shift of Pb 5d core levelbinding energy on Cu(111),the surfactant-assisted epitaxial growth of Co on Cu(111)using Pb as a surfactant,and the spin exchange splitting of ultrathin Co films onCu(111)using synchron radiation photoemission spectra as well as Auger electronspectraand low energy electron diffraction.

On the basis of our calculations,the low-energy luminescence peaks experimentally observed can be identified as electronic interband transitions induced by the O substitutional impurities.

我们的计算结果表明，实验中观察到的低能发光峰是硼氮纳米管中氧替位杂质所引起的带间复合发光所致。

The mutagen mechanism is presumed single factor dominant.(4)There was 85 percent transvertion in mutagen spectra, and they were all G:C→T:A transvertion. The maximal possibility of mutagen mechanism is analyzed as followed:ion beam implant → breakage cell surface and enter the interior → stimulate plentiful radical born → radical oxidize and damnify DNA → G becomes 8—oxoG → 8—oxoG pairing A → result in G:C→T:A transvertion(5)Production of transition was presumed that ion beam implantion damnified DNA, stimulate activity of MMR interveniented by methyl reducing.

诱发突变谱中碱基颠换比例是0.85，且是全部G：C→T：A颠换，推测低能离子束诱变鼠伤寒沙门氏菌得分子机制可能为：离子注入→通过破坏细胞表面进入内部→刺激产生大量自由基→自由基氧化损伤DNA→G变成8氧—7，8—二氢鸟嘌呤(8—oxoG)→8—oxoG与A配对→导致G：C→T：A颠换。
