病因大多数导致中枢神经系统表面含铁血黄素沉积症的慢性反复蛛网膜下腔出血都是少量和静息性的，但是相当比例（最多可达40%）的患者表现为忽然发作的头痛和脑膜炎样症状。

When the mice pre - sensitized were infected with RSV, the pulmonary inflammation, lymphocyte and eosinophils infiltration and cell - collar peribronchiles were more severe in lung organization and bronchiole than those in the single RSV infection group.

结果病理检查证实小鼠感染RSV后发展为典型的间质性肺炎；致敏小鼠感染RSV后病变更明显，细支气管周围淋巴细胞浸润形成管套增厚，嗜酸细胞增多，炎性细胞浸润的细支气管比例显著增高。

A compound control scheme combining detaching Proportion and Integral control with Model Reference Adaptive Control based on Liapunov stability theory was formulated,which is used on the plant of direct driving electric-servo-actuator.

以直接力驱动电动舵机为被控对象，提出了一种分离比例-积分控制与基于李雅普诺夫稳定性理论的模型参考自适应控制相结合的复合控制方案，该方案充分结合了分离PI控制动态性能好和自适应控制抗干扰能力强、鲁棒性好等优点。

A compound control scheme combining detaching Proportion and Integral control with Model Reference Adaptive Control based on Liapunov stability theory was formulated, which is used on the plant of direct driving electric-servo-actuator. This scheme combined the good property of each algorithm, such as good dynamic property of the PT and strong anti-disturbance ability and good robustness of MARC.

以直接力驱动电动舵机为被控对象，提出了一种分离比例－积分控制与基于李稚普诺夫稳定性理论的模型参考自适应控制相结合的复合控制方案，该方案充分结合了分离PI控制动态性能好和自适应控制抗干扰能力强、鲁棒性好等优点。

This paper studies the effect of proportion of machine sand and fine sand on the workability and compressive strength of concrete.

The steps for preparing insecticide include: first shaking flask for fermentation, adding amidon, soya bean cake powder, cotton cake powder, protease leather, yeast powder, maize milk, magnesium sulfate heptahydrate, monobasic potassium phosphate, dibasic potassium phosphate, calcium carbonate alpha-amylase and make-up water by ratio in culture medium with 100 unit volumes; secondarily filling 100ml culture mediums in triangular bottle, then seeding BTH-13 after disinfection and culturing them until the brood-cell pulls off under finite temperature; third adopting the selected culture medium and fermenting them in full-automatic fermentation tank, acidifying the fermentation liquor after the fermentation, adding the emulsifier, and directly performing spray-drying after the compression of the fermentation liquor to prepare the wettable powder.

制备杀虫剂的步骤是：首先是摇瓶发酵，在100单位体积的培养基中，按比例加入淀粉、豆饼粉、棉饼子粉、蛋白胨、酵母粉、玉米浆、七水硫酸镁、磷酸二氢钾、磷酸氢二钾、碳酸钙、及α-淀粉酶，补充水；其次是在三角瓶中装100ml培养基，灭菌后接种BTH-13，在一定温度培养至芽孢脱落；第三是采用筛选出来的培养基，在全自动发酵罐中进行发酵，发酵结束后发酵液酸化，加入乳化剂，酵液浓缩后直接喷雾干燥制备可湿性粉剂。

Because the replication levels of A2 and MP4 in cell cultures or in cotton rat lungs were similar, the mixtures of A2/MP4 birus at the ratios of 1: 1, 10: 1, 100:1 and 1000:1 were in-oculated respectively in HEp-2 ceil cultures for the comparison in competitive replication.

将等量F212和母株A2混合后在HEp-2细胞中连续转代，在不同时间点采用差异噬斑法、核酸序列图谱分析法和限制性片段多态性法分析混合病毒群体中F212和A2的比例。

As a result, make sure the proportion of black dye is 4.2%, and the formula of the dyestuff C.I. Direct Black 19: C.I. Direct Black 168: Dyestuff I=3:1:1, and when using two surfactants, printing liquidity is better, at same time compare to printing result with national inks, and the result is that confecting inks excels national inks in soaking paper, curliness and edge definition.

最后确定黑色染料所占比例为4.2%，各染料配比为直接黑19：直接黑168：染料I=3：1：1，并且当用两种表面活性剂进行复配时，打印流畅性较佳；同时与国产品牌墨水作打印测试对比，结果自制墨水在有无洇纸和卷曲以及边缘清晰度方面优于国产品牌墨水。
