Three subjects about the sci-tech park construction, agriculture, entironment and technology were proposed. Some problems were pointed out, such as inaccurate localization, pool maneuverability, unscientific programming, pool drive power and incorrect relationship between the park and farmers. Furthermore, Pharisaism, without regard to economic benefits and vast government action are still serious problem existing.

Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.
结果]UV-B处理导致叶绿素、可溶性蛋白含量以及含水量都降低,且存在剂量效应,30μW/平方公分处理的降幅大于15μW/平方公分;UV-B辐射处理对类胡萝卜素含量的影响与花青素相同,均表现为先下降后上升的趋势,2种剂量间差异不大;2种剂量的UV-B处理均抑制了PSⅡ的电子传递,尤其是处理2 h的抑制作用最大,4、6和8 h的抑制作用有所缓解,且存在剂量效应;2种剂量的UV-B辐射均抑制了叶片的光合速率,随着照射时间的延长抑制效应加大;高剂量UV-B处理对膜系统的损伤较大,低剂量UV-B处理结果不明显。

5Ns. The peak position of N band emission as well as the distinct emission region slightly moves towards the open end of the cylindrical cavity, and this does not happen to O band emission. Radiation transport efficiency of 6% is obtained for the φ400×1200um cylindrical cavity heated by x-ray source with radiation temperature of 118 eV.
从时间分辨的X光强度轴向空间分布来看,在较长时间(约1~1.5ns)内,O带X光在整个观测缝对应的轴向范围之内均有较大的辐射强度,在X光强度空间分布的变化过程中,其强度峰值的空间位置基本不变;而对N带X光,则只在较短时间(约0.5ns)内,在整个观测缝对应的轴向范围之内可观测到X光辐射,但只在靠近输运源约300μm的范围内有较强发射,在柱腔末端600~700μm范围之内的辐射则很弱,N带X光辐射轴向空间分布曲线的峰值位置在朝柱腔末端的方向移动,移动量大约为130~250μm。

Larches of different ages have different net photosynthetic rate: the photosynthetic capacity of the young ones are bigger than that of the old ones; the stand density do not affect the net photosynthetic rate obviously; as far as the different stand classes are concerned, the diurnal changes of net photosynthetic rate is closely related to the photosynthetic active radiation. For the different layers of the crowns, there are greater ecological factors (illumination intensity, temperature, humidity etc.) on the upper layers than on the lower layers: the CO2 concentration of the lower layers is greater than that of the upper layers, which is indeed an exception; the net photosynthetic rate on the upper layers of the crown is generally greater than that of the lower layers. It showed that the CO2 concentration is not a main factor in the natural changing range of the CO2 concentration. Different directions of the crown have different photosynthetic active radiation, which is generally like exposed to the sun﹥North﹥in the shade of crown. However, the changes of net photosynthetic rate are not quite the same, which is North﹥exposed to the sun﹥in the shade of crown.
不同年龄的兴安落叶松净光合速率不同,年龄小的个体光合能力高于年龄大的个体;群团密度与净光合速率没有显著的相关关系;而对不同分级木,净光合速率日进程变化规律与光合有效辐射有着密切的联系;林内树冠不同层次各生态因子有上层大于下层的趋势,而CO2浓度在下层的含量高于上层,净光合速率上层普遍大于下层,说明在林内自然CO2浓度变幅内,CO2浓度不是主要因子;兴安落叶松树冠不同方向的光合有效辐射不同,一般向阳﹥北向﹥背阴,而净光合速率变化有北向﹥向阳﹥背阴的趋势。
