Compared with NDM or STZ group, DM adversely and significantly affected all parameters of sexual behavior (P.001, P.01 or P.05), mount, intromission and ejaculation latency significantly prolonged, mount or intromission of frequency and hit rate significantly decreased, the number of mount, intromission and ejaculation behaviors significantly decreased, but no significant difference between NDM and STZ groups.

三组雄性大鼠与发情雌鼠交配后，DM组与NDM组或STZ组相比，所有参数均明显改变（P.001，P.01，或P.05），即爬高、插入及射精潜伏期明显延长，爬高频率、插入频率及命中率明显降低，爬高、插入及射精活动鼠数明显减少，而后两组相比，上述参数均无显著性差异。

Offspring were then tested for male sexual behavior: mount frequency, MF;mount latency, ML;intromission frequency, IF;intromission latency, IL;ejaculation latency, EL;post ejaculatory interval, PEI;hit rate and female sexual behavior;approach latency, AL;mount return latency, MRL;intromission return latency, IRL;post ejaculatory refractory period, PER;lordosis quotient, LQ. Measures were made at the age of postnatal days 70 to 91, and 97 to 101, respectively.

Based on the 3-D acoustic equation and Tarantola′s generalized inversion theorem, taking into consideration the character of cross-well survey, a 2.5-D cross-well waveform tomography method in the frequency domain is presented here.

从频率域3-D声波波动方程出发，结合井间观测方式的特点，基于Tarantola广义反演理论，提出了一种频率域2.5-D井间波形层析成像方法。

The thyristor static state invertor's frequency range is narrow, if time sensor change, cannot carry on the frequency control.

晶闸管静态逆变器的频率范围窄，如感应器改变时，不能进行频率调节。

But for Irkutsk to the Great Wall Station circuit,there is little relationship between the fading depth and frequency.It seems that the relationship between fading depth and frequency is controlled by the factors such as location,distance etc.

但依尔库茨克－南极长城站电路的衰落深度与频率、时间无关，说明衰落深度与频率、时间的关系还要受距离、位置等因素的影响。

The jammer receives the radar signal and modulates it in frequency domain, and then the modulated signal is retransmitted.

阐述了利用正弦信号进行频率调制的干扰机理，分析了干扰信号的频率特性，推算了决定干扰效果的各项关键参数。

In this study,two SNPs of chicken FASN gene were chosen to analyze genetic diversity and their associations with chicken growth and carcass traits by using a F_2 designed resource population.Results showed that:(1) In the PCR-RFLP site of HaeⅢ,allelic frequencies differed much among different chicken breeds,as B frequencies are the highest in Red Jungle Fowl(0.85),and the lowest in Taihe and Yugan Black(both 0.21).In the PCR-RFLP site of PstⅠ,A frequencies are the highest in Chongren Partridge(0.5),and the lowest in Naked Neck chicken(0.19),and the difference of gene frequencies was small among chicken breeds.

研究了脂肪酸合成酶(Fatty acid synthase， FASN )基因最后1个内含子2个突变的多样性，并运用资源参考家系研究了这2个突变对鸡体重、脂肪沉积性状的影响，结果表明：(1)红色原鸡Hae Ⅲ-PCR-RFLP位点B基因频率为最高(0.85)，泰和鸡及余干乌黑鸡为最低(0.21)，品种间差异较大，但未发现肉用与蛋用鸡种间的差异；在Pst I-PCR-RFLP位点上， A基因频率在崇仁麻鸡中表现为最高(0.5)，在裸颈鸡为最低(0.19)，品种间差异较小。

Since its establishment, the Tibetan People's Radio has persisted in making good Tibetan radio programs. It now has 42 programs broadcast in standard Tibetan, including 21 hours a day for news in Tibetan, and 18 hours a day in the Kamba dialect.

Vertically put the KAS detector on the upper part of the transmitter cover, turn EAS detector power supply switch on, EAS detector displays radio frequency output center frequency is: 8.2±0.05MHz; Adjust R15 (counterclockwise decrease, clockwise increase) can change radio frequency output center frequency.

把 EAS 检测仪垂直放置于发射机壳上部，按动 EAS 检测仪电源开关， EAS 检测仪显示射频输出中心频率为：8.2±0.05MHz ；调节 R15（反时针减少、顺时针增大）可改变射频输出中心频率。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
