查询词典 broadcast relay

The roots of spring-sown maize and summer-sown maize could touch with each other in relay-planting system, which made the roots competed for water and nutrition. Thus, more of the water and nitrogen in those soil layers were used, which led to the decrease of water and nitrogen in those soil layers.

玉米根系数量和TTC还原总量在剖面分布上均发生交叉，春、夏玉米间存在养分与水分的竞争，使根系所达到的区域土壤养分和水分利用量增加，从而使相应土层土壤全氮含量和水分含量下降。

The results showed that, no matter mono-cropping and relay-planting, the grain SS activity of spring-sown maize and normal summer-sown maize were decreased at the early stage after anthesis, but after 40 DAA the decrease speed were slow and could maintain a high activity for a long time, which were benefit to the sucrose formation, accumulation and transportation.

结果表明，不管单作还是套作条件下增施氮肥前期春玉米和普通夏玉米籽粒SS活性略有降低，但花后40天后其活性降低慢，能长时间维持较高的值，利于蔗糖的合成、积累和转移。

At the same time, there were complementation of water and nitrogen between spring-sown maize and summer-sown maize in the system of relay-planting. Spring-sown maize could get water and nitrogen from the summer-sown maize zone, and also the roots of summer-sown maize could touched to the regions of spring-sown maize to get water and nitrogen.

同时，套作体系中春、夏玉米存在对氮素和水分的互补利用，春玉米根系可以伸展到夏玉米区，而夏玉米也可以吸收利用春玉米区，从而达到养分与水分的互补利用。

Relay-planted with the same spring-sown maize, the quantity of nitrogen absorption of late maturity summer-sown maize was highest, but their nitrogen use efficiency was lowest, which because most the nitrogen absorbed were left in organs except grain.

与同一春玉米品种套作时，夏玉米为晚熟品种的吸氮量均较高，但其氮利用效率却较低，所吸收的氮更多的滞留在籽粒以外的植株器官中，向籽粒中转移的较少。

2 Effect on yield and quality The results indicate that relay-cropping with summer-sown different maturity maize cultivars, there are no obvious effects on biomass, grain yield, and nutritive values (crude protein yield, crude fiber yield, crude fat yield) of the same spring-sown maize cultivars.

2.2 产量及营养价值差异研究结果表明，套作对春玉米生物产量和营养价值影响不显著；但能显著影响夏玉米的生物产量和营养价值。

But relay-cropping with spring-sown different maturity maize cultivars can obviously affect the biomass, grain yield, and nutritive values of the same summer-sown maize cultivars.

当夏玉米为同一品种时，夏玉米生物产量和营养价值表现为：与春玉米LD14套作＞与春玉米YD22套作＞与春玉米YD13套作。

No matter mono-cropping and relay-planting, the increase of nitrogen use could improve the SPS activity of spring-sown maize and high oil summer-sown maize at the stage of 20 DAA, but decrease those of normal summer-sown maize.

无论单作还是套作，增施氮肥使春玉米穗位叶花后20天的SPS活性增强，但套作时高氮却使穗位叶SPS略有下降；增施氮肥使普通夏玉米穗位叶SPS活性下降，高油夏玉米穗位叶SPS活性增加。

Relay is applied to the control system of traditional hydraulic pressure quenching machine tool using leaf spring.

传统的板簧液压淬火机床，其控制方式为继电器控制，因而控制系统的工作可靠性差，导致淬火机床故障率高、维修成本增加。

Three methods of judging gap Spark-over at power frequency spark-over test on the three phase combinative surge protector of TBP type were analyzed,namely change of indication on ammeter A1,A2 or operation of current relay.

通过对TBP系列三相组合式过电压保护器的工频放电试验，分析了三种判断间隙击穿放电的方法，即电流表A1指示是否有变化；电流表A2指示是否有变化；或电流继电器是否动作及其对放电电压值的影响。

Clock synchronization mechanism of three control network were described. A tuning algorithm of the slave clock was presented. The tuning algorithm does not relay on any specific motion control networks. An ARM7–based implementation of the IEEE1588 protocol was developed.

本文讨论了三种控制网络的时钟同步机制，提出了适用于多种网络的从时钟的调整算法，给出了基于ARM7系统的IEEE 1588协议的实现。

A carrier gas such as nitrogen is directed through line 20 and valve 22 to connect with line 26 and mix with the gas sample.

如氮气之类的载体通过管线20和阀22引入，与管线26相通，与气体样品混合。

But for the most part, knaves and parasites had the command of his fortune

然而支配他的家产的大多是恶棍和寄生虫。
