An interview guide, entitled "Maternal Perception of the Onset of Lactation", was also used to obtain milk secretion data. Results found a mean onset of lactation of 78.2±18.7 hours (range=42 to 121 hours). The prevalence of delayed lactation onset was 43.6%(n=58). Slighly over half of participants (56.9%, n=33) were primiparous. Parity, total second stage of labor duration, duration of second labor stage beyond one hour, and perinea wound pain were the most significant predictors of delayed lactation onset.

研究结果发现：(1)首次泌乳时间的平均值为78.2±18.7小时（范围42至121小时）；(2)产妇自觉延迟泌乳的发生机率为43.6%(n=58)，其中初产妇占56.9%(n=33)，经产妇占43.1%(n=25)；(3)产次、第二产程时间、第二产程时间大於一小时、第一到第三天会阴伤口疼痛分数，是延迟首次泌乳时间的重要预测因子。

By setting the retting duration of 20 hours, the factors affecting the residual gum percentage of the retted kenaf fibers are studied. The experimental results show clearly that the following factors have the significant influence on the residual gum percentage of the retted kenaf fibers and show the obvious variation tendency. The preferred processing parameters are as follows: pH value 7. 0、bath ratio 1: 50、reuse percentage of retting liquid 50%、air flow volume 2. 5L/min、temperature 40℃、nitric additives (ammonia is better than nitrates) percentage 0.45%.By comparison with anaerobic retting, the retting duration using aerobes is much shorter than that using anaerobes.

确定了以好氧微生物脱胶作为本课题的脱胶路线后，在特定的脱胶时间（20小时）条件下，通过分析不同参数条件下的残胶率，研究了好氧微生物脱胶的各种影响因素对红麻脱胶的影响规律，并优选出最佳脱胶液回用比为50％，最佳pH值为7.0，最佳气流量为2.5L/min，最佳浴比为1：50，最佳水浴温度为40℃，最佳含氮添加剂为铵盐类化合物，最佳含氮添加剂用量为0.45％。

The echolocation signals of Rhinolophidae and Hipposideridae are both long CF-FM with 1 harmonic and narrow FM bandwidth. But Rhinolophidae has longer duration, higher duty cycle and lower dominant frequency than Hipposideridae. All the echolocation signals of Vespertilionidae are short FM with 2-6 harmonics and wide FM bandwidth. Vespertilionidae has shorter duration and lower duty cycle than the other two families. There are obvious differences in dominant frequency between different species in this family.

菊头蝠科和蹄蝠科回声定位信号均为长CF-FM型，一般具有1个谐波，调频带很窄，但菊头蝠科的持续时间和能率环明显高于蹄蝠科，蹄蝠科能量最大处频率高于菊头蝠科；蝙蝠科回声定位信号均为短FM型，具有2～6个谐波，持续时间和能率环比其他两科低，调频带很宽，能量最大处频率在种间变化较大。

Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. Previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly-varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, In hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed.

若这些海上建筑物的上部结构底高程较低，在恶劣海况下当大波浪在其面板下面通过并与之接触时，面板下面除了作用有强度变化较缓慢的波压力外，在波峰刚接触到面板时尚存在着历时很短但强度极大的冲击压力，这种极强冲击荷载会引起建筑物的整个上部结构失稳或造成局部破坏。

Often, the cooldown is 3 times the proc duration, but some are longer, and some procs thad do do not give a buff for a certain duration incur a cooldown as well.

一般这个时间是特效持续时间的三倍，但是有些会更长，也有些特效的BUFF不会有内置CD。

It is proved that, while tested on short duration testing rig, the turbine power, rotation rate and flow rate require special testing method, and that, for testing the overall turbine performance, the short duration testing rig equals to, and even outruns continuous testing rig in accuracy. All the parameters need to be tested synchronically.

指出： 短周期涡轮试验在功率、转速、流量等参数的测量方法上有其特殊性；在总的涡轮性能测试指标上短周期涡轮试验完全可以达到，甚至超过连续式涡轮试验的精度；在短周期涡轮试验中，需特别注意各测量参数的同步性。

The area of steel ring of the assembly sample was enlarged thus to keep the temperature field even and to protect the anvils from excessive heating. The pause pressure was chosen to be 90% that of synthesizing pressure; the pause duration to be 500~600 s. Our newly developed linear no-power depressurization technique was used for uniform depressurization. The synthesizing duration was selected to be 40~50 min, and the stop-heating time was delayed by 20 s.
