In fact this new product, namely Sukano PLA dc S511, is based on polylactic acid and can be used in PLA processing to eliminate disadvantages such as yellowing of the material and also its slight milkiness.

事实上，这种叫做Sukano PLA dc S511的产品是基于聚乳酸应用的，它可以用于PLA加工以消除PLA黄变和PLA轻微的乳白色调。

Methods Forty-two patients with acute critical diseases were stochastically divided into two groups, namely, the treatment group and the control; both groups were treated with routine integrated method, while the treatment group was treated additionally with rhubarb powder nasally or orally; detection was made on the hemorhcological indexes of the two groups before and after the 7 days' treatment.

Crystal qicai raised ultraviolet VFX, that is, fast-curing properties of the Crystal, the ink holdout colorless, unscented, non-volatile, cured yellow screen leakage membership card after line non-proliferation, there are the obvious Crystal, having raised emergent, smooth and join qicai foil powder, with extremely colourful, in the light, people from different angles to watch, there will be an honour for the extraordinary variety of art refringence for free!

水晶七彩瘪下殊效，即诳骗紫外线飞快固化水晶油不朱的共性，其不朱层无色透明、无气息、不挥发，固化后不泛黄，丝网漏会员卡制息后线条不清除，有水晶般的明不隐瘪下突现，晶莹剔透，平滑细致，参增七彩箔粉后，又明灭着极其灿艳的色彩，在光芒照射下，人们从差别的角度观察，会有不别致的耻辱幻变反射般的艺术吃苦。

Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.

研究结果显示，两孔记录的古气候波动可与深海氧同位素曲线进行对比：对应于深海氧同位素曲线第6阶段(MIS6)，堆积厚层的河道相粗颗粒沉积及第3硬土层，反映当时气候寒冷；第5阶段(MIS5)，为滨海湖沼沉积，沉积物的颗粒显著变细；第4阶段(MIS4)，本区形成第2硬土层；第3阶段(MIS3)的早期，本区也发育滨海湖沼沉积，中晚期则形成潟湖—砂坝体系，在滨海平原区普遍发育粉、细砂层；第2阶段(MIS2)，地层由下粗上细的沉积序列构成，下部为黄灰、棕黄色粉砂，上部则为棕黄色或暗绿色硬粘土。

The main ore_stage alterations related to hydrothermal fluids include ①early K_silicate alteration,②silicification,③ pyrite_sericite_quartz alteration and ④propylitization.

成矿期间与矿化热液活动有关的蚀变主要有：①早期钾硅酸盐化；②红柱石次生石英岩化；③黄铁绢英岩化；④青磐岩化。

However, the image-retrieving environment is so complicated, such like from a nature object to a variety of objects, from a light environment to a dark environment, or from a nature light to a daylight in office, the properties of objects, and the varieties of light sources and light intensities. These complex external image-retrieving environments let users can not get an accordant image quality. Such under a tungsten lamp, the image appears yellowish and reddish; under daylight in office, the image becomes greenish and bluish.

CCD Camera面对的是复杂的取像环境，从自然景物到各式各样的景物，从光亮环境到灰暗环境，或从自然光到办公室日光灯、景物的特性、光源的种类及光线的强弱，这些外在复杂的取像条件及变因往往让使用者无法得到相当一致的影像品质，如在钨丝灯下拍摄的影像，将产生偏黄、偏红效果的影像；在办公室的日光灯下将产生偏绿、偏蓝效果的影像。
