By contrast with the WPPM, the other treatments, especially the straw mulching, both of the root and the leafage can not get sufficient growth before July because of the low temperature, and after then, there was plentiful rainfall, so the leafage and stems still accumulated the assimilation products that should be distributed to ear. that led to the reductions of their economic outputs.The yield of maize covered with WPPM was the highest.

秸秆覆盖和露地的玉米在整个生育期内，尤其是秸秆覆盖，出现了各器官生长发育紊乱(如根系、根叶组等生长不充分和茎、穗叶组等过剩生长)的现象，导致了生育后期茎叶与穗争夺有限的光合产物，干物质积累不适时、分配不合理和最终经济产量的降低。

The relation between evapotranspiration and leaf area index of different treatments is better with a much linear functional relationship.

Currently there are two kinds of radio navigation resources in our country. One is the Changhe Ⅱ loran, which mainly overlays inshore regions of our country and serves for ships. The advantages of this system include the strong transmitting power, the wide overlaying region, and simple receiving technique.

我国目前现有的无线电导航资源有两种：一个是"长河二号"无线电远程导航系统，主要覆盖我国近海区域，主要为舰船提供导航，该系统发射功率大，覆盖广，接收技术简单，其缺点是导航精度低，在两个台链的结合部会出现盲区。

This showed that capacity of water-holding in biological soil crusts were obvious improve,and effected precipitation permeate or water second distribute process.The study results of"fertile islands"formation mechanism in biological crusts showed that biological crusts layer cover could increased nutrients content for below sand soil through precipitation permeate washing,and it promoted plants assimilate more nutriment.The matter import ways of biological soil crusts fertility island had many ways,including the effection of living macrobiotics metabolism in crusts levels,wind-sand flow of near surface,dust deposition and plants decomposition course,etc.Source of particle matter in biological soil crusts was wind-sand flow of near surface,and not dust deposition.Biological crusts layer cover had preserved effection for nature water content in 0-5cm soil layer,compared with the sand of no biological crusts layer,effecting precipitation permeate,and could not obvious restrained from the water evaporate process indoor experiment.

生物结皮层肥岛形成机制的研究结果表明：生物结皮层覆盖能够通过降水淋溶作用而增加下层土壤养分的含量，进而促进植物对养分的吸收；生物结皮层养分输入有结皮生物代谢、降尘、风沙流和植物分解矿化作用等多(来源：A73e3B3eC论文网www.abclunwen.com)种途径，但生物结皮层的颗粒物质来源主要是近地表风沙流，而不是大气降尘；生物结皮层覆盖对0-5cm土层自然含水量有一定的保护作用，并影响降水向深层渗透，不能有效的阻止表层水分的蒸发进程；研究表明采取人工促进技术能够在流动沙丘上形成生物结皮层，实现流动沙地的快速治理。

If coering it up is the difference, then whether you coer it up with moleskin ... or you coer it up with duct tape, maybe the point is you're coering it up,'' he said.

他说："如果覆盖能产生不同的结果，那么你可能选用厚绒垫，也可能选用布基胶带，可能意义就在于你覆盖它"。

Due to the mobile sensor is expensive and moving will consume a lot of energy. We used a small part of mobile sensor and most part of static sensors to meet the demand of k-coverage of three-dimensional network, and we have analysis the ratio of them is 1/(2πk^1/2. To achieve k-coverage, we have received the maximum moving distance for mobile sensor is O(log^1/3 in a network with a size of L . At last, we established a mathematical mobility model for mobile sensors, and converted the sensor redeployment for k-coverage into maximum network flow problem, and proposed a distributed relocation algorithm and verified it through experiment simulation.

考虑移动传感器移动会大量消耗能量，且比较昂贵，使用小部分的移动传感器和大部分静止传感器来满足网络k-覆盖的密度需求，且分析了其密度之比为1/(2πk^1/2；并证明了网络要达到k-覆盖传感器需移动的最大距离为O(log^1/3；建立传感器移动数学模型，将传感器重新部署问题转化为最大网络流问题，提出分布式重新部署算法并实验仿真证明其有效性。

Operator observes normal dropped-call statistics for one or two months, but then the dropped call rate starts to increase without having anything done to the network. Does this mean our analysis is not as meaningful as we envision it to be? This can be explained by looking at the subscriber growth trend.

但是在网络建设后期，用户量较大的情况下作网络分析时如果得出覆盖问题的结论通常局方不太认可，究其原因是：网络在一个月或两个月前掉话率指标还是正常的，当前网络覆盖状况和前阶段没有变化的前提下为什么掉话率指标会上升。

To cover or surround with mulch.To cover with or as if with an openwork fabric or structure.

覆盖网络简单说来覆盖网络就是应用层网络，它是面向应用层的，。。。

The present study investigatated the effect on the diversification of weed community, including weed abundance, dominance, evenness, biomass, and mean height after mulching straw and intercropping white clover in the tea plantation from 2005 to 2006. The results were as follows: 16 families and 31 species were found in total. In April, the dominant species characterized with slow growth, lower biomass, and less than 30 cm height; in July those who grow faster with higher biomass and height became dominant; In September, these malignant communities reduced, while the oxalis and diffusa characterized with lower biomass and low height gradually increased. In the three seasons, the weed abundance, community diversity and evenness increased, and the dominance, the biomass and average height of weeds remarkably reduced after intercropping white clover and muching straw.
