ARDS occurs more frequently in patients with preeclampsia/eclampsia, once patients show tachypnea and abnormal arterial blood gas, ARDS should be attentioned, the key treatment is comprehensive management leading by inspiring oxygen with pressure support ventilation by non invasive ventilator with a positive-end expiratory pressure should be used earlier.

重度子痫前期／子痫患者较易并发ARDS，一旦病人呼吸改变或血气异常，应警惕ARDS，治疗关键在于及早应用机械辅助呼气末正压通气吸氧为主的综合治疗。

In Chapter Ⅰ of this volume the writer presented an argument for the issue of combing the different "Historical Books" of Tanach, and referred that we should combine the historical recordation of Torah with "the Former Historical Books" as a whole and regarded the Books of Ezra-Nehemiah as "the Later Historical Books".

第一章说明了《塔纳赫》中不同的&历史书卷&应该如何组合的问题，指出应将《妥拉》部分的历史记载与&前期历史书卷&组合在一起考察，而将《历代志》和《以斯拉—尼希米记》作为&晚期历史书卷&一并加以考察。

The results shows that the tapetal expanding abnormally occurs in dyadphase stage, microspore abortion occurs in the early of monokaryon stage, disaggregation in the end of monokaryon stage, only some spall of microspore is observed in monokaryon stage, the four cell walls also exist, the tapetal cells became completely vacuolated, almost filled the whole locule. vascular bundle of male sterile line anther vanish at mature pollen stage.

结果发现花药绒粘层在二分体时期发生异常，小孢子在单核前期开始败育，至单核后期完全解体，花药发育后期不育系药腔中只观察到少量的小孢子残体，花药壁的四层细胞依然存在，绒粘层细胞已经彻底液泡化，占据了药腔的整个空间，花粉成熟期不育系花药维管束消失。

The relationship between parameters of the Richards equation and the N accumulation and translocation was studied by path analysis .

同时，积累中期和前期的积累速率和积累量对大麦穗部氮积累和转移的影响也较大。

During the preresearch on the testing well location selection in the south of western depression, three kinds of process and research work have been done according to the log datum on Well Moushen:(1)Formation analysis and formation pressure evaluation which verdicts that formation under 5198.5m is not of Trias, whereas is still in Permian, and abnormal formation pressure phenomenon exists in Members 1 and 3-4 of Shahejie Formation;(2)Re-interpretation of oil and gas formation and evaluation of reserve formation;(3)Evaluation of oil source rock. Members 1 and 3-4 source rocks of Shahejie Formation have good capability of oil generation.

在东濮凹陷西洼南部探井选位的前期研究中，根据该井的测井资料情况，做了三方面处理和研究工作：①地层分析和地层压力评价，认为5198.5m以下的地层不是三叠系而仍是下第三系，沙一段和沙三段—沙四段存在高压异常；②重新解释油气层和评价储集层，在沙三段—沙四段发现6层12.87m厚可疑油层；③评价油源岩，认为沙一段和沙三段—沙四段油源岩具有较好的生油能力。

In the course of present investigation in interspecific hybrid of Tritical crops, cytomixis mas observed at microspore stage, the present investigation deals with detailed analysis of this phenomenon at different conditions.

作者在麦类远缘杂种的减数分裂过程中发现，在减数分裂Ⅰ的前期和小孢子时期均存在核穿壁的现象，并对各种状态下的穿壁现象进行了详细的观察研究。

Is highly debated. Microscopic studies using DMACA staining revealed flavanols in shoot tip cells of Tsuga Canadensis during the early anaphase and in prophase nuclei.

用DMACA染色法的显微研究表明在在加拿大铁杉茎尖细胞分裂后期的早些阶段及细胞分裂早前期的细胞核中都有黄烷醇存在。

The results showed that the higher levels of plant growth substances, namely hearty physiological metabolism were necessary for tuberization, but there was no direct relationship between one substance only and tuberization.

块茎形成需要这些物质的大量积累即体内旺盛的生理代谢，特别是前期较高水平的生长物质是植株生长发育及块茎形成良好的基础。

Appropriate nutrient supply could keep higher ZT content at initial stage and higher ABA, JA and IAA content and lower GA content at middle period, which could satisfy the demand of important hormones in every stage of tuberization and keep GA/ABA and GA/JA at reasonable levels during tuber formation.

而合理营养水平供给，保持了前期较高水平的ZT含量，中期较高的ABA、IAA、JA含量和较低的GA含量，保证了块茎发育各时期对重要激素的需要，GA/ABA和GA/JA在块茎发育各时期也保持在合理的水平。

Were analyzed under different nutritional levels. The results showed that in tuber development, under- or over-supply of nutrients reduced ZT content at initial stage and IAA, ABA and JA content at middle stage, but increased GA content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

结果表明，过低、过高的营养供给，降低了块茎发育前期细胞分裂素的含量，中期细胞生长素的含量以及促进块茎发育的脱落酸、茉莉酸含量，增加了各时期促进匍匐茎发生的赤霉素含量，导致在块茎形成和膨大的关键时期，GA/ABA和GA/JA比值失衡，抑制了块茎的正常发育。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
