缺

The Theory of Reasoning by Default is put,forward to interpret the phenomenon of discourse coherence: when meeting a discourse, the reader/listener will have stimulated some default assumption before a full comprehension...

缺省推理理论的提出就是从认知角度来解释连贯现象的一种尝试：读者或听话人在遇到一个语段时，总是在充分理解之前就已激活某种缺省预设，从而个人不同的观念通过语言得以沟通。缺省预设是语言理解的前提和心理基础。

In this model, baryon is described as a bound state of one quark and one clustering diquark.

从本质上讲这也是一种对称破缺，但这种破缺有独自的意义，它主要涉及SU(6)破缺效应波函数中的第一项，在存在夸克聚集这一观点上对该项进行了变形。

With this method, we had several important differences compared to the YDmodel. First, the ratio of daily increment of PDT and the deficit of both water and nitrogen was used to estimate the effect of environment. Second, a nonlinear function was adopted to describe vernalization and thermal effectiveness (instead of three-stage linear function). Third, sinusoidal function was used to describe photoperiod curve cluster for different cultivars.

本模型在YDmodel基础上的改进主要有3点：（1）将每日生理发育时间的增量乘以水肥丰缺因子，改为除以水肥丰缺因子表现水肥对大麦发育的影响，客观体现了大麦在水肥丰缺条件下的发育延迟或提早现象；（2）将三段线性函数改为非线性函数表达春化效应和相对热效应，确立了不同品种相对春化效应和相对热效应的曲线族；（3）将线性函数改为正弦函数表达不同品种光周期效应。

In the low B condition of the soilless culture, rapeseed seedlings were short of B, the seedlings were short and the leaves were malformed and the weight of the shoots decreased, the branch roots were fewer and snuff color, the weight of roots decreased, and the length of root and the ratio of shoot/root decreased, too. However, the high B- efficiency type of rapeseed had the a great ability to the low B stress, the growth of shoots and roots were better than the low efficiency, and the B concentration range of the rapeseed varieties which responded to the B scarce was 0.001 mg/L to 0.01 mg/L.

营养液培养条件下，苗期缺硼，甘蓝型油菜植株瘦小，叶片皱缩，地上部生长量下降；侧根少且呈现黄褐色，根重、根体积、根长以及根冠比下降；高效品种具有较强的耐低硼胁迫的能力，表现为同等缺硼条件下，对高效品种地上部和根系生长的抑制作用都相对较小，且品种间对缺硼反应差异最大的硼浓度范围为0.001mg／L—0.01mg／L。

A two-year study on the effects of three densities D1, 80±5 stemsm^(-2; D2, 140±8 stemsm^(-2); and D3, 220±11 stemsm^(-2) of Fargesia denudate in a F. denudata-Picea purpurea natural forest on the F.

在缺苞箭竹－紫果云杉原始林下，选取3个密度(D1、D2、D3)的缺苞箭竹，研究了密度对缺苞箭竹凋落物量、养分归还量及养分利用效率的影响。

It was different of contents of same mineral element inthe leaves of Malania olefera because of different areas, but the differences was notnotable. The influence of mineral element and soil elements on Malania olefera wasnitrogen, iron, manganese, zinc, potassium, copper from most to least, and four ofthem were belong to microelement. However, the lack of copper and serious lack ofzinc and iron in the soil influent the growth of Malania olefera. It had been made through the analysis of morphologic and anatomicalcharacteristics of root, stem, leaf, flower, fluid and seed that Malania olefera notonly had the primitive character but also had the evolution character, which had thevital significance on Olacaceae classification.

砂粒含量比大，通透性良好的土壤适宜蒜头果的生长；六个不同分布区土壤的有机质和全N含量极为丰富，速效K的含量水平中等，而土壤速效P的含量富贫差异较大；分布区土壤部分缺Cu，严重缺Zn、Fe；蒜头果叶片中的叶绿素含量与立地条件有着密切的关系；龙虎山样地立地条件比其他样地更适合蒜头果生长；不同立地上生长的蒜头果叶片中同一矿质元素含量有一定的差异，但差异不显著；土壤元素对蒜头果生长的影响由大到小依次为：N、Fe、Mn、Zn、K、Cu，其中四个是微量元素，而分布区土壤缺乏Cu，严重缺Zn、Fe而影响了蒜头果的生长发育。

According to seasonal change of soil moisture, it can be divided into stable period , consumptive period (June-September) and slow restorable period (September-October).

各植物群落土壤水分亏缺可分为重度、中度和轻度亏缺三种类型，且其季节变化明显；群落对土壤水分亏缺的适应对策因植物种而异。
