Reinhardtii; by 13梸20% or 12?20% in S. obliquus; by 35挆81% or 29~79% in C. pyrenoidosa, respectively. On the other hand, specific growth rate in low or high P media, when CO2 concentration increased from 10 to 51 and 99~tM, increased by 13-46% or 10-44% in C. reinhardtii; by 15梸20% or 8-42% in S.

此外，当CO_2从10μM增加到51和99μM时，莱因衣藻的比生长速率在低P条件下增加13～16％，在高P条件下增加10～14％；斜生栅藻的，在低P条件下增加15～20％，在高P条件下增加8～12％；蛋白核小球藻的，在低P条件下增加20～44％，在高P条件下增加26～111％。

Result Under common condition of water body, the growth of S. obliquus accelerated along with the increment of P concentration in water body with optimum P concentration being about 2 mg/L. Both low and higher P concentration would play certain limiting function on the growth of S. obliquus.

结果］在通常水体情况下，斜生栅藻的生长随着水体磷浓度的升高而加快，斜生栅藻生长的最适磷浓度为2mg/L左右，低浓度和较高的磷浓度都会对斜生栅藻的生长起一定的限制作用。

And whether is it necessary to redefine the geotectonic pattern in southern China? In 1993, the authors discovered firstly the late Paleozoic radiolarian silicalite in the "Shuangqiaoshan Group", which, as we know, is a block within the ophiolitic mélange. In 1996, the authors discovered again the late Paleozoic fossils in the other rocks of "Shuangqiaoshan Group" and "Zhitang Formation" of Lower Sinian Series in the ophiolitic mélange. At the same time, the authors discovered firstly the early Paleozoic chitinozoa fossils.

因此，再次将&板溪群&是否是前震旦纪的一个变质地层单位、江南古陆是否存在以及华南大地构造格局是否需要重新厘定等问题提了出来。1993年笔者于赣东北蛇绿混杂岩带内的&双桥山群&岩块中，首次发现了含晚古生代的放射虫硅质岩。1996年又在该混杂岩带多处的&双桥山群&岩块和&下震旦统志棠组&中找到了含晚古生代的放射虫硅质岩，还首次在&登山群拔竹坑组&中发现了早古生代的几丁虫化石。

The results were as follows: 1 at normal or high temperature, the selected asphaltene dispersant could reduce the association of asphaltene molecules, 2 hydrogen-transfer of FCC decanted oil and its sub-fractions were evaluated by using anthracene and 9,10-dihydroanthracene as chemical probes, one of sub-fractions could be taken as hydrogen-donor.

本文首先从渣油生焦的关键组分沥青质入手，为热处理降蜡筛选抑制生焦的添加剂，在生焦率低于0.1w%的前提下，提高热裂解降蜡的深度。

Quality of sliver forming is tested using Uster AFIS single fiber testing system under different integrated conditions for the rear hood of the card A186F equipped with back teeth guided flat with cotton web cleaner for the 3-step gauges and cotton web cleaner for 4-step wind throughput. Test shows that gauge excess small or excess large will result in poor quality of sliver forming.

为了研究棉网清洁器反齿导向盖板隔距大小和风量大小组合对生条质量的影响，采用Uster AFIS单纤维测试系统，对A186F梳棉机后罩板采用棉网清洁器的3档反齿导向盖板隔距和4档棉网清洁器风量，在不同组合条件下生产的生条质量进行了检测，检测结果显示，过大与过小的反齿导向盖板隔距对生条质量均有不利影响。

The Ordos Basin is a large-scale sedimentary basin in Northwest China. From bottom up, the hydrostratigraphic units in the basin are pre-Cambrian metamorphic rocks, lower-Paleozoic carbonate rocks, upper-Paleozoic to Mesozoic clastic rocks and Cenozoic deposits.

鄂尔多斯盆地是我国西北地区的大型构造沉积盆地，以前寒武系变质岩为基底，依次沉积了下古生界碳酸盐岩、上古生界一中生界碎屑岩和各种成因的新生界，总厚度达6000m。
