奶牛细管冻精解冻后低温保存可提高受胎率

中国奶牛 2001年第5期 38-38页

作者：傅春泉金华市家畜良种推广站金华321017

奶牛细管冻精输精具有污染少、使用简便、受胎率高的优点,正取代奶牛颗粒冻精及低温精液成为奶牛人工授精用精液的主要剂型.但由于细管冻精的甘油含量高,解冻后在常温下不易保存.据我们实验观察,甘油在低温下对精子有一定的保护作用,但... 详细信息

奶牛细管冻精输精具有污染少、使用简便、受胎率高的优点,正取代奶牛颗粒冻精及低温精液成为奶牛人工授精用精液的主要剂型.但由于细管冻精的甘油含量高,解冻后在常温下不易保存.据我们实验观察,甘油在低温下对精子有一定的保护作用,但随着温度的升高,甘油对精子产生明显的危害作用.细管冻精和颗粒冻精解冻后不同温度保存的保存效果就能说明不同甘油浓度与温度对精子的危害程度,见表1.

Nonadiabatic holonomic quantum computers serve as the physical platform for nonadiabatic holonomic quantum *** quantum computation has entered the noisy intermediate-scale era, building accurate intermediate-scale nonadiabatic holonomic quantum computers is clearly necessary. Given that measurements are the sole means of extracting information, they play an indispensable role in nonadiabatic holonomic quantum computers. Accordingly, developing methods to reduce measurement errors in nonadiabatic holonomic quantum computers is of great importance. However, while much attention has been given to the research on nonadiabatic holonomic gates, the research on reducing measurement errors in nonadiabatic holonomic quantum computers is severely lacking. In this study, we propose a measurement error reduction method tailored for intermediate-scale nonadiabatic holonomic quantum computers. The reason we say this is because our method can not only reduce the measurement errors in the computer but also be useful in mitigating errors originating from nonadiabatic holonomic gates. Given these features,our method significantly advances the construction of accurate intermediate-scale nonadiabatic holonomic quantum computers.

建立了致密油藏分段压裂水平井不稳定渗流数学模型,利用有限元法对其进行求解,分析了分段压裂水平井的流动阶段特征,对比了不同非均质情况下分段压裂水平井压力动态曲线的特征。研究表明:非均质性主要影响压力动态曲线第一径向流、第二线性流和晚期拟径向流阶段:当压裂区域与未压裂区域的基质流度之比α小于1时,α越小,压力动态曲线越向右上方移动,压力传播到油藏封闭边界的时间越晚,且压力导数曲线在晚期拟径向流阶段呈现"下凹"趋势。当α大于1时,压力动态曲线在晚期拟径向流阶段的斜率逐渐减小,且α越大,曲线越偏下。
