新疆博格达地区中—新生界碎屑成分自中侏罗世的中晚期开始发生了巨大变化，主要表现在：自中侏罗世晚期开始，沉积重矿物组合及相对含量发生较大变化，不稳定重矿物、较高级别变质岩岩屑明显增多，显示此时发生的物源属性变化及构造活动的存在；自侏罗系西山窑组沉积晚期开始，砂岩碎屑成分中的沉积岩碎屑明显增加，显示盆缘沉积岩物源的隆升和剥蚀作用。

Bamboo first crystallizes then lignifies during bamboo shoot growth and basically forms crystal structure in one month. 1-year-old bamboo culm ends growth and its height,thickness, volume almost change little, but culm tissue is small and tender and there is more water and less substance in it. Bamboo crystal proportion keeps invariable during this period.2-year-old bamboo culm begin to lignify,its cellulose proportion debases and its crystal proportion decreases. Bamboo lignin debases, crystal proportion changes a little in the end of this period.Many-old-year bamboo culm crystal proportion is almost invariable. Freaky bamboo cell wall crystal region's thickness is less than normal bamboo's. Bamboo cross section crystal area and the ratio of long axis to short axis are less than normal bamboo's,and roundness,irregular index, the fiber cap density per unit area increase more than normal bamboo's.

The results showed that different topping frequency (at intervals of 15 d, 30 d, 60 d, 90 d) had no evident influence on total wine loss, volatile acid content, T-SO2,F-SO2, wine colour, and wine pH values. Under constant temperature and humidity conditions, total wine loss was closely correlated with the using degree of Chinese barrel and the storage time in Chinese barrel. Volatile acid content slightly rose along with wine storage time. The content of SO2 dropped rapidly during 15 d after wine filling, but dropped tardily ever since. Wine colority rose remarkably during 15 d after wine filling, but climbed tardily ever since. Wine colority change was unstable, it changed wavily and depressed on the whole. In conclusion, it was recommended that the best topping interval was 90 d.

结果表明，橡木桶15 d、30 d、60 d、90 d添桶间隔对红葡萄酒的酒液损失总量、挥发酸含量、T-SO2、F-SO2、颜色、pH值无显著影响；在恒温恒湿的条件下，红葡萄酒的酒液损失总量与橡木桶的新旧程度、桶贮时间密切相关；随桶贮时间延长，葡萄酒中挥发酸略有上升；葡萄酒入桶后15 d内SO2含量急剧下降，以后则缓慢下降；葡萄酒入桶后15 d内色度显著上升，但随后变化平缓，总的趋势是随桶贮时间延长色度缓慢上升；葡萄酒的色调变化不稳定，呈波浪式变化，总的趋势是降低；建议中国橡木桶桶贮红葡萄酒的添桶间隔为90 d。

The comparative research results showed that:(1)Thediurnal variation of the net photosynthetic rates in the aquatic leaves was a "double-peak", with an various "midday-decline", the time of the peak value appeared at about 10:00 A.M. and 13:00 P.M., while that in the xeric leaves was showed with invarious peak value and "midday-decline"; The diurnalvariation of transpiration ratesof both aquatic and xeric leaves appeared as a single-peak, the appearance time of peak value of the latter was earlier than the former and gradually decreased in the afternoon; The stomatal conductances appearance time of both of them were close to that of photosynthesisrate ,reached to the maximum in the morning and then gradually decreased: Diurnal variation of intercellular CO2 concentrationshows that: both aquatic and xeric leaves increased at first, and then exhibit a tendency of ascending within narrow range.(2) The net photosynthetic rates, photosyntheticallyactive radiation, stomatal conductances and transpiration ratesof both two kinds of leaves showed positive correlation, The correlation degree among them was prominent, there was significant negative correlation between The net photosynthetic rates and intercellular CO2 concentration.

The highest occupied molecular orbit and the lowest unoccupied molecular orbit are calculated, and the energy gap of the two orbits determines the activity of the reagents, and yet, in an alkaline solutions for flotation, the HOMOs of the corresponding ions decide the rigidity of the reagents and therefore determine the reaction activity with different rigidity metal cations in minerals, which vary flotation performance to different minerals, and the experimental results were verified.

药剂与矿物作用的能量计算结果表明：苯氧乙酸类抑制剂与方解石和一水硬铝石作用后的能量变化均为负值，能量变化有利，可以形成稳定的吸附；而与黄铁矿作用后的能量变化为正，能量的变化是不利的，故不能形成稳定的吸附，表现出较弱的抑制作用。

Scientific evidence that climate change is under way, is man-made, and is likely to continue happening forms the foundation for an edifice of policy which is intended to transform the world's carbon-intensive economy into one which no longer spews greenhouse gases into the atmosphere.

科学证据证明气候正在变化，变化是人为造成的，而且还会持续变化。这些证据正在催生大量的政策，以促使世界由现在的高碳经济向不排放温室气体的经济模式转变。

Time is the reflection of change means there are occurrences of time as long as there are changes, i.e.

时间是变化的反映就是说，只要有变化就有时间的发生，或者说，没有变化就不会有时间。
