Two sibling species Helicoverpa armigeraH(u|¨bner and H.assulta are serious crop pests in China.They have the similar morphological,biological and ecological characterstics,as well as they can even hybridize with each other.Their host plant ranges, however,are quite different.The former is a typical polyhpagous species,and its host plant range including at least more than 60 crop species such as cotton,corn,wheat,soybean, tobacco,and tomato,and 67 wild plant species from about 30 plant families including Malvaceae,Solanaceae,Gramineae,Leguminosae,etc.

Kg-1. d-1 was administered in a single daily dose;in the second group,Netilmicin (200 mg/d) was combined with cefazolin (3 g,Q12 h);and in the third control group,the combination of cefazolin and Amikacin was used. Pharmacokinetics were studied in 7 patients using the TDX system, and PAE induced by Netilmicin was determined by the Avantage microbiologic system. Clinical symptoms, laboratory studies, chest X-rays, and side effects were observed.

Polyaluminum chloride (PAC; PAC-S; PAC-H; PAFC) is a new high efficiency of inorganic polymer coagulant, the pure products use raw materials manufactured with advanced technology, good flocculation effect, its effect is better than the traditional aluminum sulfate and water purification molysite ordinary inorganic coagulants and general polyaluminum chloride.

聚合氯化铝（ PAC ； PAC-S ； PAC-H ； PAFC ）是一种新型高效的无机高分子混凝剂，本产品选用纯净原料以先进工艺制成，具有良好的絮凝效果，其净水效果优于传统的硫酸铝和铁盐等普通无机盐类混凝剂及一般的碱式氯化铝，能广泛用于给水及工业用水的净化处理，对生活污水和各行业废水也具有理想的净化效果。

In the CMKGM preparation section,with the indicators of DS andη, the optimum laboratory conditions preparation of a certain molecular weight of the high DS of CMKGM: reaction time (5～6) h, the theory of the degree of substitution (2～3), the molar ratio of monochloroacetic acid to Sodium hydroxide (2:1～3:1),the reaction temperature (55～65)℃, liquid ratio (10:1～12:1)mL/g, containing enthanol (50～70)%.

CM(来源：5e60ABC论文网www.abclunwen.com)KGM制备工艺研究中，以取代度、表观粘度为指标，建立了制备一定摩尔质量的高DS的CMKGM的实验室制备条件：反应时间(5～6)h、理论取代度(2～3)、氢氧化钠与氯乙酸摩尔比(2：1～3：1)、反应温度(55～65)℃、液料比(10：1～12：1)mL/g、乙醇体积分数(50～70)%。

The analytical results have shown that p ro ducts mainly consisted of some monosubstituted, disubstituted and a few trisub stituted naphthalenes. Except the low activity of HZSM-5 catalyst, all other z eolite catalysts have higher activity. HY and Hβ catalytic activities were the highest, and their naphthalene conversions attained to 79.12 and 55.79 percent respectively, but their selectivities for 2-isopropylnaphthalene, 2,6-diisopropylnaphthalene(2,6-DIPN) and 2,7-diisopropylnaphthalene ( 2,7-DIPN) were too low. ZM catalysts had good activity and much better selecti vity, especially for ZM4-3, of which its 2,6-DIPN/2,7-DIPN ratio was 2.97. Th er efore, some zeolite catalysts are recommended for shape selective isopropylat ion of coal tar naphthalene.

研究结果表明，煤焦油萘异丙基化产物主要由一取代萘、二取代萘以及少量三取代萘组成；除HZSM-5活性较低以外，其它催化剂均有较高的反应活性，其中HY和Hβ反应活性最高，萘转化率分别达75.15％和55.96％，但β位产物的选择性较差；ZM类催化剂既有一定的活性，又有较高的β选择性，是萘择形异丙基化反应理想的备选催化剂。
