钾

The most sensitive part to K ftertilization was in the mid-upper midrib at low positions. The relative value of K content, expressed by Vm/Im, in the midrib between 5th and 1st leaves from top, was used for evaluating the K nutrient status of banana. The sampling part was in the connective zone between midrib and blade.

明确了采用自顶向下计第5叶和第1叶叶脉含钾的比值，来评价香蕉的钾素营养状况；叶脉采样的代表部位为叶片与叶主脉的连接带和采用混合样分析的可行性。

In MVNn, the activation of muscarinic cholinergic receptors leads to a decrease in a voltage-insensitive K+ current,which corresponds to the leak K+ current.

在MVNn中，毒蕈碱引发的M受体去极化效应是由钾电导的减少所介导，并证明所抑制的离子电流是漏钾电流。

It is a pity," I went on, with an amused laugh, as the thought occurred to me,"that this Bellford and I could not be kept side by side upon the same shelf like tartrates of sodium and antimony for purposes of identification.

由于想到了这个想法，我好笑接着说：&遗憾的是这个贝尔福德和我不能像酒石酸锑钾和酒石酸钾钠一样为了辨认的目的并排放到同一个架子上。&

Compared with other antiseptic,SDA can make food have non-harm,fresh,good taste,long stire,low price etc merits.

称双乙酸钠与其它防腐剂相比，经添加SDA的食品，具有无毒、鲜美、口味纯正、储存期长、价格地、低等优点，特别是既没有山梨酸钾的异味，又没有丙酸钙的涩味，更没有苯甲酸钠的怪味，又因为双乙酸钠为钠盐，不会影响食品的绵软。1/3-1/2量的双乙酸钠抑菌效果与丙酸钙相当，与等量的梨酸钾防腐效果相当，但价格极为低廉。

Under the open-field condition, it was investigated that foliage spraying potassium ferrate degraded organophosphorous pesticides in spinach.

在露地栽培条件下，研究了叶面喷施高铁酸钾水溶液对菠菜中有机磷农药的降解作用，并探讨了高铁酸钾对菠菜相关酶活、MDA含量及品质指标的影响。

Grain total protein content, and prolamine and albumin content increased by N application for high-oil corn and high-starch corn, and also increased by P and by K application for high-oil corn.

氮磷钾营养平衡施用较不施氮、不施磷和不施钾显著增加优质玉米产量，使高油玉米（农大115）分别增产15.9%、6.9%和12.1%，使高淀粉玉米（白玉109）依次增产20.3%、8.6%和12.7%。

Study on the Effective Separation of Potassium Chromate and Potassium Carbonate Ⅰ.

篇名 铬酸钾－碳酸钾高效分离研究Ⅰ。

Methods: Copper was determined by catalytic kinetic spectrophotometric method which was based on the copper catalyzing oxidation of brilliant green by potassium chlorate and hydrogen peroxide in potassium hydrogen phthalate-sodium hydrate buffer solution at pH4.20. The absorbance was measured at 624 nm.

在pH4.2的邻苯二甲酸氢钾－氢氧化钠缓冲溶液介质中，利用铜离子催化氯酸钾和过氧化氢氧化灿烂绿的指示反应，通过测量624 nm下吸光度的改变，用催化动力学光度法测定痕量铜。

Through modifying proportions of potassium nitrate, sulfur, phenolophthalein and potassium hydrate, formula of charcoal-free black powder is optimized by replacing charcoal with reactant of phenolphthalein and potassium hydrate.

以酚酞和氢氧化钾的反应物替代木炭，通过调整硝酸钾、硫磺、酚酞及氢氧化钾的混合比例对无木炭黑火药配方进行优化设计，对比研究了普通黑火药与无木炭黑火药在机械感度、静电火花感度、热分解过程及输出特性等方面的差异。
