查询词典 PN

The results showed that for the two peony cultivars, before flowering and during flowering period the day rate changes of net photosynthesis rate were up to the maximum at 12:00, and there were no photosynthesis "sleep at noon" phenomenon, therefore, during the two period, the curves of net Pn of the peony leaves only have one peak.

Nitrogen balance was positive in the EN group, but it was negative in the PN group.

此前，临床应用较多的是肠外营养支持，在取得一定效果

While PN containing FE is safe and effective in improving animal survival and nitrogen balance and can be used as nutritional support after liver transplantation.

相反，能改善肝移植受体的氮平衡，有利于动物的长期存活，可用于肝移植后的营养支持。

Character of solution of stochastic differential equation in dual of nuclear space was studied.

研究核空间的对偶空间的随机微分方程解的性质，得到微分方程组解 L 2收敛的条件，及在一定条件下解过程导出的测度{ Pn}为胎

Objectives:To investigate the effect of PN support with different times of BEE in octogenarian patients with systemic inflammatory response syndrome.

目的：探讨以基础能量消耗的不同倍数提供热能进行肠外营养治疗高龄全身炎症反应综合征病人的效果。

In order to shorten the PN code acquisition time the scheme based on the match filter is presented.

提出一种基于匹配滤波器的快速捕获算法，改善了在极低信噪比下的性能，降低了平均捕获时间。

No additional data for frequency tracking are need, but higher estimation accuracy and low computational complexity can be obtained. Finally, a kind of optimizing joint algorithm for symbol timing, frequency synchronization and channel estimation is proposed. The false alarm probability and miss detect probability of the symbol timing are derived. We proved that the time－frequency offset domain random sequence sliding in the frequency offset direction is orthogonal with the original random sequence, and proposed a new integer frequency offset estimation algorithm. The coarse estimation methods for fractional frequency offset both in AWGN and multipath channels are proposed too.

最后，提出了一种优化的符号同步、频偏估计和信道估计的联合算法，推导了符号同步方法的虚警概率和漏检概率，给出了随机序列在时间－频率偏移域沿频率偏移方向滑动后与原序列近似正交的证明，提出了一种新的在时间－频率偏移域沿频率偏移方向进行滑动相关估计整数频偏的方法，提出了在AWGN信道和多径信道下进行小数频偏粗估计的方法，给出了小数频偏细估计的ML估计结果和利用频域PN序列取值特性的简洁的信道估计结果。

PN kids should also use big crayons and big paintbrushes because their finger muscles are not yet fully developed.

托班应该使用大号的蜡笔和大号的画刷，因为他们的手指肌肉还没有发育完全。

Parenterally fed, short-bowel rat models were established.

建立PN短肠大鼠模型，随机分成普通肠外营养组及添加GH的肠外营养组。

Conelasions The combination of rhGH and Gin can significantly improve the adaptation of the remnant small intestine in parenterally fed, SBS rats, there are synergistic effects between them; The increase of proliferation and the decrease of apoptosis in the remnant intestinal epithelial cells are involved in this process; The intestinal iGF-I p; ays an important role in the intestinal adaptation. Our findings support the concept that specific gut-trophic nutrients and growth factors may combined to enhance the intestinal adaptation and reduce the severity of short bowel syndrome.

结论联用rhGH组与Gln，显著促进PN时短肠大鼠残余小肠代偿，二者间作用存在协同肠粘膜上皮细胞增生增加及凋亡抑制与小肠代偿密切相关；小肠局部IGF-I在rhGH与Gln协同作用的发挥中起重要介导作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
