中国米质气候资源的地域分布

稻米品质受着气候条件的明显影响。在我国不同地域，米质气候资源各不相同，对米质的影响也各具特色，总的趋势是，北方优于南方；西部优于东部；晚茬口水稻优于旱茬口；在地形复杂地区，米质气候资源还具有垂直地带性结构。我国丰富的米质气候资源为各种类型优质米的生产创造出优越的环境条件。     

The spatial and temporal distribution of total ozone over China

In this paper the grid data of total ozone mapping spectrograph (TOMS) installed on Nimbus-7 satellite (1978 to 1994) was used and the spatial and temporal distribution of total ozone over China was analyzed. The research indicates that the Qinghai-Tibet Plateau destroyed the latitudinal distribution of total ozone of China and the low value closed center emerged over Qinghai-Tibet Plateau. Long time change trends of seasonal total ozone of Qinghai-Tibet plateau are provided. It shows that the most obvious decrease of total ozone occurs in winter (Jan.), then in summer (Jul.), the relevant slow change occurs in autumn (Oct.) and spring (Apr.).     

Adsorptive removal of phosphate by the bimetallic hydroxide nanocomposites embedded in pomegranate peel

This study aimed to fabricate new and effective material for the efficiency of phosphate adsorption. Two types of adsorbent materials, the zirconium hydroxides embedded in pomegranate peel (Zr/Peel) and zirconium-lanthanum hydroxides embedded in pomegranate peel (Zr–La/Peel) were developed. Scanning electronic microscopy (SEM), x-ray photoelectron spectroscopy (XPS) and x-ray diffraction (XRD) were evaluated to give insight into the physicochemical properties of these adsorbents. Zr–La/Peel exceeded the adsorption efficiency of Zr/Peel adsorbents in batch adsorption experiments at the same pH level. The peel as a host can strive to have a strong “shielding effect” to increase the steadiness of the entrenched Zr and La elements. La and Zr are hydroxide metals that emit many hydrogen ions during the hydrolysis reaction, which contribute to protonation and electrostatic attraction. The highest adsorption capacity of La–Zr/Peel for phosphate was calculated to be 40.21 mg/g, and pseudo second-order equation is very well fitted for kinetic adsorption. Phosphate adsorption efficiency was reduced by an increase of pH. With the background of coexisting Cl^?, little effect on adsorption efficiency was observed, while adsorption capacities were reduced by almost 20–30% with the coexistence of ${{\text{SO}}_4}^{2?}$, ${{\text{NO}}_3}^{?}$ and humic acid (HA).
