属灵与属世在理性上的和谐统一

“属灵”和“属世”是广大基督徒在基本信仰不变与所处时代不断相适应的提高升华的实践过程。应当承认，中国神学思想建设目前仍处于初创与发展的第一阶段，但神学思想建设的主流势不可挡，其旺盛的生命力和蓬勃的生机已经显现出来。它之所以得到中国教会和广大信徒的支持，根本原因是它代表了中国基督教前进的方向，它是中国基督教三自爱国运动在21世纪与时俱进的时代产物，它是中国基督教兴旺的希望之所在。

A New Gleicheniaceous Fern Chansitheca (Sphenopteris) wudaensis from the Lower Permian of Wuda, Nei Mongol, China

Chansitheca (Sphenopteris) wudaensis sp. nov. is described based on the materials collected from the Lower Permian Shansi Formation of Wuda, Nei Mongol, China. The frond is small and at least two times pinnate. The pinnule is sphenopteroid. The sori are borne on the abaxial surface of the pinnule, arranged in two rows parallel to the midvein, elliptic,and composed of 4-10 round sporangia. The indusium is absent. The annulus is transverse and complete, and consists of about 18 thickened cells. The features of the fertile parts, sori, sporangia and annulus and the absence of indusium indicate that the new species belongs to the Gleicheniaceae.

A New Species of Araucarioxylon Kraus from the Early Early Permian, Nei Mongol, China

A kind of silicified fossil wood with mixed pits on the radial tracheid wall is described. The fossil wood was collected from the top of Taiyuan Formation (early Early Permian) in Wuda Mining District, Nei Mongol. Compared with the Paleozoic fossil woods in the world, it is put into Araucarioxylon Kraus and named as A. laoshidanense sp. nov. Based on the character of possessing mixed pittings (alternate and opposite pittings) on the radial tracheid wall, the fossil wood is believed to be one of the unknown primitive conifers.Diagnosis of the new species: Only secondary xylem preserved and consisting of axial tracheids and rays. Growth ring boundary, resin duct and axial parenchyma absent. One to Four (commonly 2 or 3) seriates of bordered pits (mostly alternate but sometimes opposite) on the radial tracheid wall. One to Four (commonly 1, rarely 2 to 4) Cupressoid pits in each cross_field. Rays usually uniseriate, sometimes partly_ biseriate and 2 to 39 (mainly 3-5) cells high.

Infructescences formally allocated in Trochodendron sp. were reviewed and assigned to Amersinia obtrullata. Leaves described as Populus carneosa, Celastrophyllum subprotophyllum, Viburnum antiquum, V. asperum, Viburniphyllum finale, Protophyllum wuyunense, P. cf. haydenii, P. ovatifolium, Credneria inordinata were also restudied and assigned to Beringiaphyllum pseudoantiquum.

First report of subgenus Phoenicopsis(Czekanowskiales)from Middle Jurassic of Ordos,China and its paleoclimatic implications

Subgenus Phoenicopsis （Phoenicopsis） assigned to Czekanowskiales is recognized and a new species, Phoenicopsis （Ph.） ordosensis sp. nov. is first reported fi＇om the Middle Jurassic Yan＇an Formation of the Ordos Basin, alternate based upon the leaf gross morphology and epidermal structures. The new species has linear leavs in bundles of five to six attached on a short shoot, more than 100 mm long by 5-6 mm wide, containing 10-12 parallel veins at upper portion. The leaf is hypostomatic. Epidermal cells are longitudinally arranged with smooth periclinal wall on the upper cuticle. The narrow non-stomatal zones and wide stomatal zones alternate in the lower cuticle. Stomata in four to five irregular spaced rows are longitudinally oriented in each stomatal zone. Guard cells for each are surrounded by four to five subsidiary cells with undeveloped papillae. Anticlinal wails of ordinal3, epidermal cells are nearly straight and periclinal walls slightly papillate. The new species shallow stomatal pits kept open and surrounded by unevenly undeveloped bulges. These characters are consistent with those of growth in a humid, rather than an arid climate. The presence of subgenus Phoenicopsis and other taxa of Czekanowskiales in the coal-bearing Yan＇an Formation supports the view that the climate in the Ordos Basin was humid and warm with seasonal changes during the Middle Jurassic.

Discussion on Middle Jurassic metallogenic mechanism of Au-Mo polymetallic hydrothermal deposits in eastern Jilin

In the Middle Jurassic,a large-scale tectonic-magmatic activities and hydrothermal mineralization occurred in the eastern Jilin province.The deposit types consist of the orogenic gold deposit,porphyry molybdenum deposit and skarn gold deposit,etc.,which constitute regional hydrothermal metallogenic series.The magmatic bodies related to mineralization belong to calc-alkaline series,which are characterized by active continental margins.The above-mentioned different types of deposits formed in a uniform tectonic setting,which resulted from the combined processes between the subduction of Pacific plate under the Eurasia plate and the persistent post-collisional convergent forces between the North China plate and the Siberian plate.The mineralizations were happening in the deceleration period,after which Paleo-Pacific plate was strongly subducted under the Eurasia continental block,i.e.transition period from compression to extension.

Heavy Metal Contamination of Well Water in the Kipushi Mining Town （Democratic Republic of Congo）

Concentrations of eleven heavy metals （AI, Cd, Co, Cu, Cr, Fe, Mn, Mo, Ni, Pb and Zn） and pH determination in water from nine spade-sunk wells of 2-15 meter depth, five drilled wells of 30-72 meter depth, and two water supply faucets in the Kipushi mining town, south-east of the Democratic Republic of Congo, were investigated from February to July 2011. The results were compared with the World Health Organization （WHO） drinking water pH and heavy metal guidelines. Mean concentrations of Pb in water from four spade-sunk wells and three drilled wells, those of A1 and Fe in water from four and two spade-sunk wells, and those of Cd in water from four drilled wells were higher than the WHO drinking water maximum permissible contaminant limits of 0.01 mg/L, 0.2 mg/L, 0.3 mg/L and 0.003 mg/L respectively, probably due to the mining activities carried out in Kipushi for about 90 years. The pH mean values of water from five spade-sunk wells and three drilled wells were lower than the WHO drinking water pH optimum of 6.5-9.5, suggesting that the water from those eight wells was not conform to the chemical quality of water for human consumption.

Health Risk Assessment of Heavy Metals in Groundwater： The Effect of Evaporation Ponds of Distillery Spent Wash

The current study was carried out to examine the heavy metals （Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn and As） concentration in GW （groundwater） samples in the vicinity of distillery spent wash evaporation ponds and RGW （reference groundwater） samples collected 2 km to 3 km away from the source. The study examines the potential health risk caused by consumption of heavy metals to local inhabitants living around distillery spent wash evaporation ponds. HM （heavy metals） concentration was determined by AAS （atomic absorption） and the results were compared with permissible limits of PEPA （pakistan environmental Protection Agency） and WHO （World Health Organization）, set for industria effluents and drinking water. The health risk assessment such as CDI （chronic daily intake） and HQ （hazard quotient） were determined on the sources ofHM concentration. The cm of heavy metals in GW were found in following decreasing order Fe, Zn, Mn, Ni, Co, Cu, Cr, Cd, Pb and As. The HQ indexes of HM in the GW samples near the distillery spent wash evaporation ponds was in the order As, C, Ni, Cu, Mn, Zn, Pb and Cr. The results showed that the distillery spent wash is the cause for the change in HM contents of the study area.

A key to 10 species of genus Protorthophlebia is provided.

Earliest fossil fruit record of the genus Paliurus(Rhamnaceae) in Eastern Asia

The genus Paliurus is characterized by its distinctive orbicular-winged fruits and a trilocular(or bilocular) ovary. Macrofossil records suggested this genus was distributed widely in North America, Europe, and Asia during the Paleogene and Neogene, before its present limitation to Eurasia. In this study, we describe some Paliurus fossil winged fruits from the lower part of Youganwo Formation(middle Eocene) and Huangniuling Formation(late Eocene) of the Maoming Basin, South China. These fruits are recognized as Paliurus favonii Unger based on a detailed study on the fossil morphology and cuticle characteristics. This represents the earliest occurrence of Paliurus fossil fruits in eastern Asia, and to date is the world's lowest latitude appearance for this genus. The most ancient records of Paliurus throughout the world are from the middle Eocene of North America and the late Eocene of Japan, leading some researchers to conclude the Paliurus may have originated in North America. Molecular data, however, do not support this hypothesis. The present Paliurus fossil fruits provide new evidence for the origin and phytogeographic history of this genus.
