Continuous observations using the video recording system showed that in the three biotypes,the earliest copulation events occurred 2-6 h after emergence and 56-73%of females copulated at least once by 12 h after emergence.

3B型烟粉虱与ZHJ2型烟粉虱的生殖隔离程度与同型雌雄虫之间的交配次数和频率相比，B型烟粉虱和ZHJ2型烟粉虱之间的交配次数显著减少，交配频率显著下降。

From point of view of Fourier theory, an optical system behaves as a low-pass filter which debars spatial frequency information about the object beyond the diffraction limit cut-off frequency.

按照傅立叶光学的观点光学系统是一个低通滤波器，其传递函数在由衍射极限分辨力所决定的截止频率以上值均为零，因此图像截止频率以上的能量和信息被丢失。

In this paper, firstly the influence of the delamination upon the natural frequencies of a laminated beam is studied in detail. By partitioning the delaminated beam, its natural frequencies are obtained.

本文首先详细分析了层合梁的脱层现象对其振动频率的影响，通过对脱层梁进行分区处理，得到了脱层梁自振频率变化的规律。

能将当地频率和携带者的频率联合起来产生能解调和放大的超音频信号。

A radio receiver that combines a locally generated frequency with the carrier frequency to produce a supersonic signal that is demodulated and amplified.

能将当地频率和携带者的频率联合起来产生能解调和放大的超音频信号。

The frequency of mIPSCs increased gradually with depolarizing membrane potential and it attained to the maximum as the membrane potential was held at +10mV.

随着膜电位的去极化，mIPSC的频率逐渐升高；当钳位电压升至+10mV时，mIPSC的频率达到最高值。

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。

The key problem for limb , skin or other composite tissues transplantation is to control posttransplantation rejection , which encumbers long term functional survival of transplanted organ and tissues .

作为皮肤复合组织移植的受者，术后出现排斥反应的几率很高，排斥反应发生的程度和频率将直接影响移植组织能否长期存活及功能能否及时恢复，而免疫抑制剂的个体化用药是否合理又直接影响术后免疫排斥反应发生的频率和程度，因此为受者&量体裁衣&制定免疫抑制剂术后个体化给药方案，是保证移植组织或器官有功能性的长期存活的关键因素之一。

Your energy frequencies need to be in tune with what you want attract in your life.

你的能量频率需要调到你生命中需要吸引的那个频率。

Research results show that when the frequency of excitation signal is within 10kHz to 100kHz the wave in free bolt and grouted rockbolt is guided wave which is related to its boundary conditions. Waves with different frequencies have different velocities.

研究结果显示在测试激发波的频率范围内(10~100 kHz)，锚杆中传播的波是一个和边界条件相关的导波，不同频率的波在锚杆中传播的速度不同。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
