以酸性水稻土为研究对象,通过水稻盆栽试验,分析了在不施加生物炭(CK)、只施加一年生物炭(B1.和连续两年施加生物炭(B2)处理下,不同生育期稻田土壤全磷(TP)、活性磷(P_(SoL)、P_(M3))、中稳态磷(Pi_(oH)、po_(oH)、P_(HCl))、高稳态磷(P_(CL)、P_(oCL))含量及占比的动态变化差异,讨论了稻田土壤遗存磷指数(LGC)、磷饱和度(DPS)、磷吸附容量(SoR)对生物炭添加施用的响应特征。结果表明,与CK相比,B1.理的土壤活性磷含量在分蘖期显著降低、成熟期显著增加,中稳态磷含量在分蘖期显著增加,高稳态磷含量各时期均无显著变化。B2土壤活性磷含量在抽穗期和成熟期均显著增加,中稳态磷含量在分蘖期和成熟期显著增加,高稳态磷含量无显著变化,但占比在抽穗期与成熟期分别显著降低1..8%和27.8%。B1.B2处理LGC和DPS均显著增加,且B1.理土壤SoR在抽穗期显著增加。因此,生物炭添加显著增加了稻田土壤活性磷和中稳态磷的含量与占比,降低了植物利用率较低的高稳态磷的占比,说明生物炭施加增加了稻田土壤遗存磷和生物有效磷含量。研究结果明确了稻秆生物炭施用后稻田土壤磷的稳定性及有效性的变化特征,为稻田土壤磷素管理提供了合理化建议。

We report the design concept and performance of a compact, lightweight and economical imaging polarimeter, the Triple Range Imager and poLarimeter(TRIpoL), capable of simultaneous optical imagery and polarimetry. TRIpoL splits the beam in wavelengths from 400 to 830 nm into g′-, r′-and i′-bands with two dichroic mirrors, and measures polarization with an achromatic half-waveplate and a wire grid polarizer. The simultaneity makes TRIpoL a useful tool for small telescopes for the photometry and polarimetry of time variable and wavelength dependent phenomena. TRIpoL is designed for a Cassegrain telescope with an aperture of^1.m. This paper presents the engineering considerations of TRIpoL and compares the expected with observed performance. Using the Lulin 1.m telescope and 1.0 seconds of integration, the limiting magnitudes are g′~1..0 mag, r′~1..5 mag and i′~1..0 mag with a signal-to-noise ratio of 1., in agreement with design expectation. The instrumental polarization is measured to be^0.3% in the three bands. Two applications, one to the star-forming cloud IC 51.6 and the other to the young variable GM Cep, are presented as demonstrations.

A 3-month enclosure experiment was carried out to examine the effects of different stocking (monoculture of freshwater pearl mussel Hyriopsis cumingii, polyculture of the pearl mussel and gibel carp Carassius auratus gibelio, and polyculture of the pearl mussel, silver carp Hypophthalmichthys molitrix and bighead carp Aristichthys nobilis) and management (fertilizing, combination of fertilizing and feeding) models on chemical water quality. During the experiment, mean value of dissolve oxygen (Do) in the enclosures was over 8.9 mg·L-1. and pH ranged from 6.99 to 1..69. The enclosures with monoculture of the pearl mussel had high Do and pH. Mean value of Ca2+, hardness and alkalinity in the enclosures ranged within 1..6-23.2 mg·L-1. 80.6-96.6 mg CaCo3·L-1.and 72.1.89.1.mg CaCo3·L-1. respectively. Mean value of nitrate (No3-N), nitrite (No2-N), ammonia (TAN), reactive phosphate (po4-P), total nitrogen(TN) and total phosphorus (TP) ranged within 0.1.5-0.202 mg·L-1. 0.002 -0.005 mg·L-1. 0.088-0.1.3 mg·L-1. 0.01.-0.055 mg·L-1. 1.906-2.989 mg·L-1.and 0.327-0.539 mg·L-1. respectively. There were no significant differences in No3-N, No2-N and TAN among the enclosures. High po4-P occurred in the enclosures in which the pearl mussel and gibel carp were polycultured with fertilizing and feeding or the pearl mussel was monocultured with fertilizing. TN and TP were high in the enclosure in which the pearl mussel was monocultured with fertilizing and feeding. Mean value of (No3-N+No2-N+TAN )/po4-P in each enclosure ranged from 9 to 1., and TN/TP from 6 to 8, respectively. No significant difference was found in ( No3-N+No2-N +TAN)/po4-P and TN/TP among the enclosures. Mean value of chemical oxygen demand (CoDMn ) ranged from 1..29 to 1..33 mg·L-1.in the enclosures of monoculture, and from 1..21.to 1..91.mg·L-1.in the enclosures of polyculture. TN and CoDMn increased, while TP decreased, with advance of the experiment. Results of the present experiment indicate using different stoc

采用9种不同的前处理方法对延安新区马兰黄土样品进行了粒度分析,以探讨不同前处理方法对马兰黄土粒度测量结果的影响。结果表明,除去有机物、碳酸盐或加分散剂后,马兰黄土的粒度分布发生明显变化,表现为中值粒径和平均粒径显著减小,粒度分布曲线向细粒方向偏移;马兰黄土中含有一定量的有机质,会影响粒度测量结果。因而,在粒度测量前处理时,需要加双氧水去除有机质;在使用盐酸进行前处理时,可能与矿物发生反应,使得所测粒径变大,且使细颗粒含量减少。综合考虑除去有机物、碳酸盐和加分散剂,前处理方法 7使样品中值粒径、平均粒径和细粒含量变化最为显著。因此,对马兰黄土进行粒度分析时,建议使用方法 7,即给样品加入1. m L浓度为1.%的H_2o_2溶液（除去有机质）煮沸使其充分反应,冷却后给烧杯注满蒸馏水,静置24 h,抽去蒸馏水,加入1. m L浓度为4%的（Na po_3）_6（分散剂）溶液后测量。
