查询词典 H

In accordance with increasing concentrations of Ca~(2+), Ca~(2+)-ATPase and H~+-ATPase activity in plasma membrane and tonoplast of cucumber root were increased significantly at first, then decreased slightly later; H~+-ATPase activity in plasma membrane and tonoplast of cucumber leaf was changed unremarkably; Ca~(2+)-ATPase activity in plasma membrane and tonoplast of cucumber leaf was increased significantly at first, then decreased slightly later.

低温下，随Ca~(2+)浓度的升高根中质膜和液泡膜Ca~(2+)-ATP酶和H~+-ATP酶活性及叶片中质膜和液泡膜Ca~(2+)-ATP酶活性先升高后下降，叶片中质膜和液泡膜H~+-ATP酶活性无显著变化，说明适当增加营养液中Ca~(2+)浓度后，可提高ATP酶的活性减轻低温伤害。

Since it is usually necessary to de-energize the winding before measuring R H, and the resistance of the coil may change rapidly as the temperature decreases, it may be necessary to determine the value of R H at the end of the test by taking several resistance measurements at short intervals, beginning as quickly as possible after the instant of shutdown.

人们一般在测R H时，通常要断掉线圈绕组的电，温度下降了线圈的电阻变化很快，所以有必要在断电的一瞬间尽快地测取电阻，而且还要以较小的时间间隔多测几次，从而得到R H 值。

Following 72 h co-culture, desquamate, sporozoites, trophozoites, meronts, microgametocytes, macrogametocytes, zygote, thin-wall oocyst, and thick-wall oocyst appeared orderly. Between the 60th and 72th hour, many oocysts emerged. Inoculated by the C. parvum -infected cell culture supernatant at the 48th hour, the immunosuppressed mice became infected.

在感染后72 h内，隐孢子虫出现连续发育阶段，包括脱囊、子孢子、裂殖子、裂殖体、滋养体、配子体、合子、薄壁卵囊和厚壁卵囊，在60～72 h内形成卵囊；用感染48 h的细胞培养上清接种于免疫抑制小鼠， 10 d后有隐孢子虫卵囊排出。

Both Hopea hongayanensis and H.mollissima were reduced into H.chinensis because tomentum is not a reliable character to differentiate dipterocarp species.

由于毛被多少不是区分种的可靠特征，因此将河内坡垒Hopea hongayanensis及多毛坡垒H.mollissima两者都归并到狭叶坡垒H.chinensis。

After 72 h,168 h to observe amount and species of the attracted flies by the six materials in the three fields.Results There is amount difference of flies among three fields( P ≤0.01).There is also species difference of flies among six materials;In six materials,"canker fish+bean draff"(3∶2) attracted the most flies.The following is "canker fish+bean draff(3∶2)+ 0.1% TH6040".

结果在3种环境下，不仅6种诱蝇材料72h、168h诱捕的蝇数有很大的差别( H =10.80，χ2≤0.01； H =10.80，χ2≤0.01)，而且各诱蝇材料诱捕的蝇类种群构成亦有所不同；以腐鱼肚肠及豆渣(3∶2)诱蝇数量最多，其次为腐鱼肚肠及豆渣(3∶2)加0.1%灭幼脲；在同一环境，各诱蝇材料间差别亦很大。

The uptake of Vg by ovaries also started after adult eclosion, of which the level markedly increased after 6 h of adult eclosion, reached a peak after 48 h of adult eclosion, and then gradually reached a plateau.

卵巢对Vg的摄取始于羽化之后，羽化后6 h开始明显上升，至羽化后48 h到达高峰，并趋于平稳。

The connection between two different approaches to singular H∞ control problems based on geometric control theory and-lossless factorization theory respectively is established. This paper illustrates the eigenspace structure of singular H∞ control systems.

文中建立了基于几何控制理论和基于J-无损分解理论的两种不同的奇异H∞控制分析方法之间的联系，并揭示了具有无穷远零点的奇异 H∞控制系统的特征空间结构。

The experimental results show that the amount of SO4^2- ions adsorbed by a C-S-H surface varies with the changes of the concen- tration and the electrovalence of cations in the solution, and after the ions are dipped in high concentration Al2 （SO4）3 solutions, the adsorption capaeityof C-S-H for SO4^2- ions increases markedly.

实验结果表明：C-S-H对SO4^2-的吸附量随溶液的浓度及溶液中阳离子的电价而变化。存高浓度Al2（SO4）3溶液中浸泡的C-S-H对SO4^2-的吸附能力明显增大。

We designed this prospectiveobservational study to assess the relationship between commonpatient risk factors for developing PONV and the occurrenceof early (0–24 h) versus late (24–72 h) emetic symptoms.

我们设计这次前瞻性观察研究的目的就是来评价病人发生 PONV 的常见危险因素与其术后早期(0–24 h)以及晚期(24–72 h)发生呕吐症状的关联性。
