The results show that the ratios of chlorophyll to carotenoid, purpurin and red pigment for four maize genotypes decrease under low P dose. Those of "7922" and "Ye107" are 0.4~0.8 times those under high P dose, with much higher decrease than in "178" and "(superscript *)082".

结果表明，低磷条件下，玉米叶片叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素均减少，其中基因型"7922"和"掖107"的叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素减少幅度较大，为高磷条件下的0.4~0.8倍，且减少幅度高于"178"和"082"。

However, the cell wall cultured at high concentration of Cu2+(10～200 mg/L) was clearly thickened and became multiple layers, and the pigment decreased and the pyrenoid became one or disappeared. Low concentration of Cu2+(0.01 mg/L, 0.1 mg/L) did not affect the growth of Chlorococcum sp., but the growth became slow and even negative beyond the concentration of 0.1 mg/L.

与对照BG11培养的绿球藻比较，0.01～1 mg/L Cu2+浓度下培养的绿球藻，细胞壁无明显增厚，色素没有多大变化，但蛋白核由一个变为多个；而在高浓度(10～200 mg/L Cu2+)下，细胞壁明显增厚为多层，色素减少，蛋白核减少并回复到1个或消失。

The effects of reaction temperature, pyrolusite dosage, initial concentration of caramel and sulphuric acid on the decolorizing rate of caramel were investigated.

结果表明，焦糖色素的降解脱色速率随焦糖色素初始浓度、硫酸浓度、软锰矿用量和反应温度的增加而增加。

The results showed that the decolorizing rate increased with the increase of reaction temperature, pyrolusite dosage, initial concentration of caramel and sulphuric acid...

对实验数据进行拟合，得到了焦糖色素降解脱色动力学模型，其脱色过程的表观活化能为24.4kJ/mol，焦糖色素、硫酸和软锰矿的表观反应级数分别为2.0，0.58和1.09。

Objective To observe the effect of dental polished surface about extrinsic stain redeposition after ultrasonic scaling and sandblasting respectively.

目的：观察超声洁治及喷砂法去除色素后，牙齿表面抛光对牙外源性色素再沉着的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
