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 response to defoliation occur firstly at the tiller level, and then ramet and genet level at the same time after grazing.

放牧后的相同时期内，分蘖层次对相同放牧强度的反应最快，源株则最为迟缓。

Our observation indicates that capsaicin as a nociceptive chemical irritant can selectively activate primary afferent C-fibers to release SP and Glu from their central terminals in the superficial dorsal horn. It seems that the release of SP and Glu acting on NK-1 and NMDA receptors results secondarily in the activation of dorsal horn neurons, transmitting nociceptive information to supraspinal structures.

以上结果表明辣椒素作为一种伤害性的刺激源，可选择性兴奋C类传入纤维，引起其分布于脊髓背角浅层内的末梢大量释放SP和Glu，通过相应受体兴奋背角伤害性感受神经元，包括上行脊-丘束投射神经元，将痛觉信息传递至脑。

We inoculated rhesus macaques by thyrocricoid puncture and observed the clinical signs, pathologic changes and so on in a short period.

A dual modulus PLL synthesizer is adopted to produce the radio-frequency generator operating between 38MHz and 150MHz, which is power amplified to drive the acousto-optic tunable filter to implement wavelength scanning of diffracting beam.

射频信号源采用双模锁相环频率合成技术，实现了在38MHz-150MHz范围内的频率输出，其经功率放大电路后驱动AOTF来实现衍射光的波长扫描控制。

In North Tibet, the advanced subduction plate started to break off, which resulted in mixture of the crust materials and mantle materials, and formed the source region of richening molten materials. The large-scale volcanic activity appeared in the central-north part of the plateau.

高原北部，先行俯冲板片发生断离，其地壳物质与地幔物质混合，从而形成板内富集熔体的源区，并在高原中、北部形成大规模的火山岩。

The plate previously subduced had started to break off, which resulted in its crust materials and mantle materials being mixed up, and formed the source region of richening molten materials. The large-scale magma activity appeared in the two blocks of Himalayan and Lhas-Gangdese.

先行俯冲板片发生断离，其地壳物质与地幔物质混合，从而形成板内富集熔体的源区，并在喜马拉雅—拉萨块体内形成了大规模的岩浆活动。

Traditional exhaust silencer can not match to the variable working conditions, thus it has difficulty to reduce noise substantially in all working conditions.

传统有源消声器的消声特性，无法随发动机工况变化，因而难以在全工况范围内取得良好的消声效果。

At the end of Mingshui Formation, hydrocarbon generated by Qingshankou source rocks migrates down along open boundary faults of concentrated ribbons at the force of overpressure,then short lateral-migration along channel sand, finally accumulated on horsts and fault terraces of the uplifted side of both sides,but in the intensive fault zone,most of the units are grabens,so it is not good for accumulation.

明水组末期青山口组源岩生成的油气在超压作用下，沿开启的断层密集带边界断层幕式下排后通过河道砂体短距离侧向运移，在两侧上升盘地垒或断阶圈闭中聚集成藏；而断层密集带内多为地堑式组合，不利于油气聚集；在成藏模式指导下刻画出47个油气富集目标区，预测石油地质储量0.5 亿t。

The effect of reactor configuration and technical parameters on the gross heat efficiency and "hot spot" temperature was investigated in an autothermal operation process of methanol partial oxidation based on the balance of mass and energy balance as well as kinetics of the reactor.
