Dent corn, as a catch crop used for salt removal, was cultivated at different densities, i.e., 7.3 （low density）, 59.7 （normal density）, and 119.5 plants m-2 （high density）, during a 50 d fallow period after cultivation of a commercial crop in a greenhouse, to analyze the characteristics of nutrient salt （N, K, mg, and Ca） uptake by roots and to study the effect of plant density on the characteristics associated with crop water use. Leaf area index for the high and normal density treatments reached extremely high values of 24.3 and 14.9, respectively. These values induced higher transpiration rates that were estimated using the Penman-monteith model with the incorporation of specific parameters for crop and greenhouse conditions. The total N, K, mg, and Ca contents in the crop canopy at harvest were 26.8, 13.0, 1.0, and 1.7 g m-S, respectively, under the high density treatment. The dynamics of salt uptake rates for high, normal, and low density treatments were evaluated by assessing weekly changes in salt content, and were subsequently compared against the transpiration rate. A positive linear relationship was obtained between these 2 parameters for all 3 density treatments and all tested salts. Hence, higher transpiration rates caused higher salt uptake rates through water absorption. On the other hand, salt uptake efficiency per unit water use by cultivation was lower in the low density treatment. Therefore, management procedures with dense planting that induce higher transpiration rates and lower evaporation rate are extremely important for the effective cultivation of corn catch crops.

＜正＞ Among transition metal oxides, Ti-oxide systems such as TiO2 （titania） and TiO have attracted considerable interests for photo-catalytic and wide band gap characters in titania, and for low electric conductivity in TiO which is preferable characteristics to apply as capacitor in integrated micro-electronic device. Hence, we desire to fabricate nano-particles to control band gaps of Ti-oxide system to adapt to the application criteria.

幼龄大鼠中独立于下丘脑的6个脑部位TRH之成熟

为了评价下丘脑以外脑部促甲状腺素释放激素(TRH)与下丘脑的相应关系,我们研究了大鼠下丘脑和下丘脑以外TRH的成熟情况。7天龄大鼠整个脑部和下丘脑以外脑部TRH的绝对增大均达到了3个月成年水平,然而龄大下丘脑的TRH浓度则在23天龄时才与成年水平一样。加之,7天龄大鼠纹状体、海马、脑桥、延髓和小脑的TRH浓度比成年水平高;斯时中脑和大脑皮质者也与成年水平相类似。这些材料表明了下丘脑和下丘脑以外TRH发育的差异,并暗示下丘脑以外TRH的成熟是独立于下丘脑的。本研究提示,下丘脑以外TRH在早年幼龄中枢神经系统内可能起着神经生理学的作用,此时,下丘脑TRH的内分泌作用还不成熟。促甲状腺素释放激素(TRH),最早是从下丘脑分离出来的,而且它的分布遍及整个脑(Winokur & Utiger等1974,mori等1982)。TRH除了有内分泌作用外,还具有神经药理学和与行为有关的性质(Wilber等1976年)。现已假定脑肽在神经元细胞体内合成并聚集成颗粒,然后经轴突输送到神经末梢(mckelvy &Epelbaum 1978)。上述这些研究提出了如下可能性,即起源于下丘脑“促甲状腺素区”的神经分泌细胞体(Greer 1951,Hal’asz等1962,martin等1972)可能发出的轴突不仅到达正中隆起以调节脑垂体分泌的促甲状腺素(TSH),而且也到达下丘脑以外的若干脑区以主要地发挥神经生理作用。在整个新生时期,下丘脑的TRH已经大量成熟(Fisher等1977),并与TSH分泌的增大相关联(Dussault & Labrie 1975)。可是,关于下丘脑以外TRH之发育变化和它的那些最早起源处,能获得的资料还有限。对机械地切除传入神经束(Brownstein等1975)和电解损伤下丘脑(Jackson & Reichlin 1977)所观测到的TRH在下丘脑内减少、在下丘脑以外不减少的结果,导出了TRH除从下丘脑产生外、下丘脑以外亦可产生这个令人感兴趣的设想。不过,这些手术性的破坏性操作可能在手术处遗留下神经分泌细胞的非生理性退变(Lincoln1978,metthews等1960,Powell & Erulkar 1962)。为了阐明下丘脑和下丘脑以外TRH在成熟期间彼此间的特殊关系,我们觉得必须查明TRH是否在下丘脑以外发育的同时在下丘脑内相随地发育。本材料表明,大鼠下丘脑以外TRH数量上的成熟是先于下丘脑的TRH。

In dye-photocatalysis, widening the wavelengths absorption range of catalysts as well as aborting the recombination of the photoexcited charge carriers(electrons-holes pairs) are of paramount *** the current study, we report the photocatalytic characteristics of four compositions composed of TiO_(2),Ti_(0.97)Cu_(0.03)O_(2), Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders for two harmful dyes(Congo red and methylene blue). The X-ray diffraction technique verified the configuration of mixed anatase and rutile phases in pure TiO_(2)and Ti_(0.97)Cu_(0.03)O_(2)powders while Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders possess anatase phase only. The changes of the band gap structure and dimensions of the unit cell volume of TiO_(2)confirm the substitution of Ti^(4+)sites by Cu^(2+)and La^(3+)ions. Remarkable widening of wavelengths absorption with formation of long absorption tails were found in TiO_(2)(3.13 e V) through insertion of La^(3+)plus Cu^(2+)ions. Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)samples exhibit a visible light band gap of 2.3 and 2.7 e V, respectively. Based on SEm images, incorporation of Cu^(2+)and La^(3+)ions influences the surface morphology of TiO_(2). The resulting Ti_(0.97)Cu_(0.03)O_(2), Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders present enhanced photocatalytic activity towards Congo red dye degradation compared to pure one under natural solar spectrum. The best Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)catalyst exhibits superior photocatalytic activity of 96% for 10 ppm CR dye in 20 min as well as above average photocatalytic efficiency of 63% for 30 ppm CR dye in 120 min. As well, it showed acceptable photodegradation activity of 52% for 30 ppm mB solution in 140 min of sunlight irradiation. The heightened photodegradation efficiency of Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)catalyst can be clarified in terms of higher ch
