您要查找的是不是：
- soil total porosity 总孔隙度
- For intergranular materials, poorly to moderately well cemented, the total porosity is approximately equal to the effective porosity. 对于由晶体构成的物质，其晶粒间含泥浆少或较少，因此总孔隙度与有效孔隙度近似相等。

- For more highly cemented materials and limestones, significant difference in total porosity and effective porosity values may occur. 对于含泥浆较多的物质或石灰岩，其总孔隙度和有效孔隙度会有很大差别。
- The total porosity and the aerate porosity decrease after the rain while the faster available porosity and the slow available porosity increase . 降雨后土壤的总孔隙度下降，通气孔隙下降较明显，同时速效孔隙和迟效孔隙增多。
- In dealing with reservoir rocks, it is necessary, because the cementing materials may seal off a part of the pore volume, to define total porosity and effective porosity. 在研究储层岩石时，因为胶结物会堵住一部分孔隙的体积，所以对于油藏流体有必要定义总孔隙度和有效孔隙度。
- Maize straw returning to the field can increase the soil total nitrogen and inorganic nitrogen content. 秸秆还田增加了土壤全氮和无机氮含量。
- Log data may be used for calculating shaly capping beds parameters such as thickness, displacement pressure, total porosity, effective porosity, permeability, sand content, etc. 介绍了根据测井资料可综合评价泥质盖层的参数,包括厚度、排替压力、盖层总孔隙度、有效孔隙度、渗透率、含砂量等。
- In dealing with reservoir rocks, it is necessary, because the cementing materials may seal off a part of the pore volume , to define total porosity and effective porosity. 在研究储层岩石时，因为胶结物会堵住一部分孔隙的体积，所以对于油藏流体有必要定义总孔隙度和有效孔隙度。
- Soil total organic carbon(STOC) under broad-leaved and bamboo forest were considerately higher than (P<0.05)those under masson pine and Chinese fir. 结果表明:土壤总有机碳含量常绿阔叶林和毛竹林显著高于杉木林和马尾松林。
- Total porosity is the ratio of the total void space in the rock to the bulk volume of the rock; effective porosity is the ratio of the interconnected void space in the rock to the bulk volume of the rock, each expressed in percent. 总孔隙度是岩石中孔隙的总体积与岩石总体积的比值。有效孔隙度是互相连接的孔隙印体积与岩石总体积的比值。两者都以百分率表示。
- However, species diversity, the biomass of understory shrub and herb, and total porosity and capillary porosity of thinning stands were a little higher than those of control stands. 间伐样地的土壤物理性质有所改善，总孔隙度和毛管孔隙度都大于对照；林下灌草生物量有所增加。
- Based on dual-porosity explanation model,we set up a calculating method of fractured reservoir porosity parameters(such as total porosity,basic porosity,vug porosity and fracture porosity). 根据双孔介质孔隙解释模型概念,建立计算裂缝性储集层孔隙度参数(总孔隙度、基质孔隙度、孔洞孔隙度、裂缝孔隙度)的系统方法,为裂缝性储集层解释及储集类型的划分提供了新的思路。
- The results show that soil total P (P T), inorganic P, organic P, Olsen P and Bray P are high in MNPK, 1.5 (MNPK), MNPK (Soybean) and M treatments, followed by NP, PK, NPK, and SNPK treatments, and low in the treatments without P (N, NK and CK 2). 结果表明 :长期施磷 ;特别是磷肥和有机肥配合施用能明显提高土壤全磷 (PT)、无机磷、有机磷、Olsen- P和 Bray- P含量 .
- Geo-statistics analysis of these data demonstrated that spatial variability of soil total P, Bray-P, CaCl_2 extractable P were obvious, and the high-P fields appeared at the shores of Zhudu, and Linzhuang harbors. 地统计学分析表明:土壤P(全P、Bray P、CaCl2浸提水溶P)呈明显空间变异;土壤高P区出现在朱渎港、林庄港两村庄附近.
- Soil total P decreased linearly with time for gray desert soil, paddy soil and fluvo-aquic soil, but did not change significantly for other soils. 在试验进行5年左右，土壤全磷含量都有所降低，以后各点表现不尽相同，新疆灰漠土、长沙水稻土和郑州潮土全磷含量随时间延长呈显著直线下降，其它试验点全磷的变化不明显；
- spatial distribution of soil total carbon content 土壤总碳分布
- Some plants push their roots deep into the soil. 一些植物的根深深长入土中。
- Such crops won't grow in limy soil. 这类作物不能在石灰质的土壤中生长。
