查询词典 instantaneous current

This paper discussed the definition of instantaneous frequency and it\'s calculation in continuous and discrete time.

The results are as follows: 1 mean length and weight tend to increase while dominant length and weight groups are noted to be increasing from Oct. 2004 to Sep. 2007; 2 by using length-weight formula, calculated weight value at the same length is higher for track-data than that for background-data; 3 growth parameters of L∞, W∞ and K respectively increase from 140.5 mm, 36.5 g and 0.28 a-1 to 186.0 mm, 118.5 g and 0.36 a-1 after artificial reef deployment; 4 appreciable increases are noted in body length and weight growth rate after artificial reef deployment, and inflexion age of weight growth increases from 2.55 to 2.58 years after artificial reef deployment; 5 there is an increase in critical biomass age from 3.21 to 3.77 years after artificial reef deployment; 6 there is a decrease in total instantaneous population mortality from 1.065 to 0.75 per year after artificial reef deployment; and 7 the overall population biomass of small yellow croaker stands at 131.5 tons.

结果表明：投礁后小黄鱼的平均体长和体重均呈上升趋势，优势体长组和体重组均向高值移动；同等体长情况下由投礁后体长体重关系式估算的体重比用投礁前的体长体重关系式估算的值大；投礁后小黄鱼个体生长方程的参数 L∞、W∞、K 值分别从投礁前的140.5 mm、36.5 g和0.28 a-1增加到186.0 mm、118.5 g和0.36 a-1；投礁后体长与体重生长速度与投礁前相比有所增大，且体重生长的拐点年龄从投礁前2.55 a提高到2007年的2.58 a；小黄鱼种群生物量增长的临界年龄从投礁前的3.21 a提高到3.77 a；小黄鱼种群的总瞬时死亡率从投礁前的1.065 a-1减小到0.75 a-1；鱼礁区小黄鱼资源量约

For double-action parallel indexing cam mechanism,the characteristics of its instantaneous center curve are determined by the mechanism's speed-ratio .

双作用式平行分度凸轮机构的速比特点，决定其瞬心线的几何特性。

The instantaneous gearbox torque at a given polished rod position (whether on the polished rod upstroke or downstroke) is the torque factor at that polished rod position multiplied by the net gearbox load at that position.

在一个指定光杆位置的瞬时变速箱扭矩（无论是上行还是下行冲程）等于那个光杆位置的扭矩因数乘以那个位置的变速箱净载荷。

Correlation analysis of the two lists of the probe signals are done by using the statistic method. Void wave instantaneous velocity probability distribution graphs and the graphs of a relation between void wave average velocities and fluxes are obtained. The comparison between the fitting lines and the theoretical formulation of void wave velocity is drap.
