A plausible charge distribution of Fe and Mo valence states is proposed, and the stability of the compounds is discussed. Polycrystalline samples of 〓(0.8≤x≤1. 5) are prepared by solid-state reaction at high temperature. The alteration of the relative content between Fe and Mo in 〓 exhibits a significant effect on the crystal structure and the ionic ordering of the compounds.

Fertilizing date presented obvious effects on root growth and distribution. Fertilization after watering was more primitive to the root in up-soil layers than before watering. Fertilization of Ca-Mg was positive to the increase of root in 5-15cm soil layer, but negative to that in the surface layer. Both fertilization date and Ca-Mg fertilizer affected root vigor obviously.

施肥时期对根系也具有明显的影响，与灌水前施肥相比，灌水后施肥有利于促进根系在上层土壤中的生长和分布；钙镁肥的施用能增加5~15cm土层根重，但对表层根的生长不利，施肥时期和钙镁肥施用与否对根系活力的影响也较大。

The dissolution remarkedly slows down when the dissolved percentage of Ti is in excess of 22% due to lower reactivity of the perovskite and the coverage from silicic acid, of which the former may be the primary reason.

当钛的浸出率超过22%以后，浸出速度显著下降，这是钙钛矿的反应活性差以及硅酸的包裹所致，而钙钛矿的反应活性差可能是浸出速度显著下降的主要原因。

Rice soup bubble can not milk, because the starch in rice soup that contains the high-phosphorus, phosphorus and easy to be absorbed, immature kidneys can not emit excessive phosphorus, making plasma phosphorus content is too high, making calcium can not be calm in the bone, the cause because of hypocalcemia tetany and early emergence of rickets.

但是米汤不可以泡奶，因为米汤内的淀粉中含有的磷高，磷又容易被吸收，不成熟的肾脏又不能排出过多的磷，使得血浆中磷的含量过高，使得钙不能沉着在骨骼上，会因为低血钙引起手足搐搦和早期出现佝偻病。

During histamine stimulation, NADPH oxidase plays a critical role in generating calcium oscillations, while xanthine oxidase may contribute to, at least in part, the increase of calcium oscillation frequency in posthypoxic PAECs.

NADPH氧化酶在组胺刺激的钙振荡的发生中发挥重要作用；黄嘌呤氧化酶的激活是缺氧引起组胺刺激的钙振荡频率增加的重要原因。

Next, the change of inorganic layer from CuCl2 to ZnCl2 was adopted and a series of alkylammonium zinc chloride hybrid perovskite (C4nH8n+1NH3)2ZnCl4(n=1, 2, 3) was prepared.

在研究了有机层的变化对钙钛矿结构和性能影响的基础上，我们也研究了金属离子不同造成的无机层的变化对钙钛矿结构和性能的影响。

Self-pollination was brought as the essential reason for causing emptied seeds by former researchers. Based on those studies, potassium antimonate and electron microscopy were used to study the calcium distribution of pollens in the micropylar canal of self-pollinated and cross-pollinated ovules and morphological changes in certain cells undergoing programmed cell death from pollination to fertilization, and observation of histo-chemical changes during microgametopyte development was performed by paraffin section.

前人研究认为自交是华北落叶松产生空粒的主要原因，本论文在此基础，运用焦锑酸钾沉淀法配合电镜观察研究了传粉后到受精前异交控制和自交辅助授粉胚珠珠孔道内花粉的钙分布情况，及此过程中细胞程序化死亡超微结构的变化，并通过石蜡切片研究了华北落叶松传粉后到受精前雌配子体发育过程及细胞内含物的变化，以研究在受精前胚珠内是否存在花粉识别与选择系统，探讨钙信号传导和花粉与胚珠相互作用及细胞程序化死亡的关系。

In this paper, the marine soft soil is mixed with 10% cement added with 0.5% NaOH and 0.5% Na2CO3 separately, which form two types of new cement-soils. Comparing with the undisturbed soil and the 20% cement-soil results in that the alkalescence additive can contribute to generate a large number of needle-like, rod-like or fibriform hydrate calcium silicate crystals. The hydrate calcium silicate crystals can inhibit the generation of calcic alum crystal which would bring expansive action. At the mean time, it can separate out hydrate calcium. The hydrate calcium silicate crystals and hydrate calcium constitute the filling and inclusions together among soil particles and on the surface of soil particles, which cut down the interstices of cement soil obviously. Therefore, the soil mass can be reinforced and the intensity can be improved.

现场试验中将海积软土与分别掺入0.5%NaOH和0.5%Na2CO3的10%水泥就地搅拌，形成两种新型水泥土，在与原状土及20%纯水泥土进行比较后，发现碱性外掺剂可以促使生成大量针状、棒状或纤维状水化硅酸钙晶体，抑制了能产生膨胀作用的钙矾石的生成，同时，有Ca2晶体析出，它们共同构成土颗粒间和土颗粒表面的充填物和包裹物，使水泥固化土的孔隙明显减小，密度和强度得到极大提高。

This is a new way for comprehensive utilization of waste fat and oil. The dropping points of lithium grease and lithium-calcium complex grease can be improved through adding the complex additives. Oxalic acid and sebacic acid are effective on lithium grease' and lithium-calcium complex grease' respe...

采用加入复合剂提高锂基润滑脂和锂-钙基润滑脂的滴点，加入草酸复合剂对所制备的锂基润滑脂的滴点的提高最为有效，加入癸二酸复合剂对锂-钙基润滑脂的滴点提高效果最好。

Meanwhile, the three-dimensional mechanical characteristics of calcium thenardite salt rock take great changes after a period of solution pervasion actions.

由于溶解渗透使得矿物组成及其结构的变化，钙芒硝盐岩在溶解渗透前后三轴力学特性差异也很大，在2.0MPa围压的作用条件下，溶解渗透49h之后，钙芒硝盐岩的强度由未溶解渗透时的46.53MPa，降低为溶解渗透后的11.42MPa：与此同时，弹性模量也由43.700MPa降低为0.834MPa。
