聂双江心体观探究——以《幽居答述》为中心

《幽居答述》是聂双江在狱中对戴伯常的答书。他从德与知、精气神的关系,以及自谦与自慊、天与心等方面对各种心性、道德概念的定义、修养的方法等问题进行了探讨,一方面拓展了良知说的本体论面相,另一方面也体现了他的心本论的特征。     

The estimation of losses of potassium and magnesium from chalky soils in southern England: laboratory studies

Abstract. Ten chalk topsoils (0-25 cm) were repacked into columns in the laboratory. After leaching similar to one year's throughflow in the field, loss of K was equivalent to between 9 and 74kg K/ha. This represented between 3 and 30% of the initial exchangeable K with which loss was poorly correlated. Loss was dependant on the soil solution concentration and was inversely proportional to potassium buffer power.
The loss of magnesium in the same columns was between 10 and 22 kg Mg/ha (6-21% of the initial exchangeable Mg). Magnesium loss was poorly correlated with exchangeable Mg.
When KCl fertilizer was incorporated into the soils, the increase in leaching of potassium was 1–35% of the K addition. Application to the top of the column resulted in less leaching than when the K was incorporated. Leaching of magnesium was increased by up to 5 kg Mg/ha.
Potassium leaching may be delayed by the underlying A/C horizon but pure chalk, with an extremely low buffer power for K, has little ability to retain K. Extremely calcareous topsoils were the most leaky although in practice it is the organic chalk soils on which it is most difficult to attain adequate K levels. On all chalk soils, maintenance of a high K level with K fertilizer is likely to cause unnecessary long-term leaching losses. Annual, rather than biennial, fertilizer applications are to be preferred.

竹林禅韵——论竹的环境意象之一

作为一种具体环境构成的植物元素，竹与其它元素一起可形成一种充满寂、空、静、虚的空无境界，具有佛家禅韵。本文通过对竹与佛教的渊源、若干竹环境实例的分析，加以论证。     

海塘盐土种竹的初步研究

讨论了在中盐中碱盐土（含盐量０．３０％～０．５０％，ｐＨ８．０１～８．９９）上引种角竹、雷竹的技术，采用及时中耕、地表覆盖、增施有机肥料以及施用微量元素等改良盐碱土措施，加快脱盐、脱钙，提高盐土种竹的成活率。     

竹材液化及竹材液化树脂胶性能研究

研究竹材在苯酚液中酚竹比、催化剂、液化温度等因素对液化的影响，当用HCl或BF3作催化剂、添加量5％、酚竹质量比2—1：1时，115℃下达到竹材完全液化。液化竹材(BL)与甲醛反应，当液化物中苯酚与甲醛摩尔比1：1．6—2．0条件下，制得室外级液化竹材酚醛树脂胶(BLF)。通过TG—DSC分析固化行为表明，BLF比酚醛树脂胶(PF)有更低的固化温度；BLF与PF出现基本一致的IR特征峰。     

强化杉木复合混凝土模板的研制

以竹材和杉木为材料,试制了杉木复合混凝土模板,并对影响板材的主要因子进行了分析。结果表明,这种模板的力学性能优于木质混凝土模板而施工性能优于竹胶合板模板。

留青展平竹地板生产工艺

留青展平竹地板采用半竹留青展平技术,通过调整软化工艺,在展平过程中保留竹青部分,制备出留青竹展平板,再通过正交组坯的方式与竹集成材芯材胶合而成。首先将毛竹去除竹节后进行对半剖分,采用纵向展平技术将留青竹片进行无裂纹展平,展平后竹板宽度在13.5 cm左右。将展平后的竹板材冷压5～7 min,压力1～2 MPa。冷却后进行刨黄面定厚和定宽处理,再与竹集成材芯材组坯热压,热压温度95～100℃,热压压力3 MPa,热压时间20 min,得到1 220 mm×12 mm×19.5 mm的留青展平竹地板。该产品丰富了竹地板的品种,开辟了竹材精深加工的新途径。
