A novel method for determination of benzoyl peroxide with spectrophotometry was developed. Inclusion ratio of β cyclodextrin to dibenzoy peroxide and benzoic acid is obtained with spectrophotometry.The mechanism of the inclusion was studied,too. The results showed that β-CD react with dibenzoyl peroxide to form a 1:1 or 2:1 host-guest complex, with the apparent formation constants of 5.0× 10~2and 2.5× 10~4 , respectively.β-CD reacts with benzoic acid to form a 1:1 host-guest complex with the apparent formation constant of 6.9 × 10~2 after the dibenzoyl peroxide was reduced by hydroxyl ammonium chloride.

建立了用β环糊精测定过氧化苯甲酰的分光光度法，并测定了β环糊精与过氧化苯甲酰和苯甲酸的包结比，随着β-CD浓度的增大，可与BPO分别形成1：1或2：1的包容络合物，包结常数分别为5.0×10~2和2.5×10~4，与苯甲酸形成1：1的包容络合物，包结常数为6.9×10~2；由于包结物的吸光度值比过氧化苯甲酰的吸光度值大大增加，建立了一种当β-CD存在下，在水溶液中测定过氧化苯甲酰的方法。

In C. indicus, the infected mechanism correlated with season. The infusoriform larvae of dicyemid mesozoan dispersal from the host to sea water in the autumn and winter, then entering host in the spring and summer. The change of dicyemid life cycle stage in the C. indicus kidney correlates with the sharp decrease of infection intensity. However, the dicyemid infection in Octopus marginatus correlates with body size, not with season.

在C。 indicus之分析中可发现，中生虫之感染与季节有关，有性幼体於秋、冬季自寄主章鱼体内扩散至外界，并於春、夏季大量进入寄主，接著在寄主体内发展，每一次生活史之时期转变，伴随著感染强度之骤降，直至成熟之菱形体时期，大量有性幼体出现肾腔中，至秋季有性幼体随寄主尿液排至外界，下一个生活史之循环接著开始。

As an artificial enzyme, it can be optimized by changing the diphenylmethane units or bridging chains or by chemical modification of hydrophobic cavities to form new host compounds. Different host compounds can recognize different guest compounds to become an supramolecular system.

不同的主体化合物能俘获不同种类的客体分子，与客体形成超分子体系，对不同反应底物进行络合和催化，达到有选择性地控制反应，提高反应速率，模拟酶促反应和分子识别的目的。

In this paper, the host-guest relationship between a general cucurbit [n=7] uril (Q[7]) or a new ellipsoid-host-symmetric tetramethyl-cucurbituril (TMeQ[6]) with hydrochloride salts of 4,4'-dipyridyl (44) or N,N'-dimethyl-4,4'-dipyridyl(dm44) was examined for confirming the interaction between cucurbituril (Q[6]) and these guests.

以七元瓜环(Q[7])和新型椭圆型改性瓜环―对称四甲基取代六元瓜环(TMeQ[6])为主体，4，4'-联吡啶的盐酸盐(44)以及N，N'-二甲基4，4'-联吡啶的盐酸盐(dm44)为客体的主客体相互作用进行了考察。

Host alterations of the root aphid, Tetraneura nigriabdominalis, among four host plants ( Eleusine indica , Oryza sativa , Zea mays , and Sorghum bicolor ) were studied by comparing adult longevity, fecundity, and population parameters in the laboratory.

於实验室中，研究粗长毛禾根绵蚜 Tetraneura nigriabdominalis (Sasaki 在四种寄主植物(牛筋草 Eleusine indica 、水稻 Oryza sativa 、玉米 Zea mays 及高粱 Sorghum bicolor )转移对其成蚜寿命、繁殖率及族群介量之影响。

In macrophages, Legionella destructed the transmission of small bubble, prevented phagosome-lysosome fusion, prevented the meaning of the sterilization of endosome and lysosome, established its own unique copy of the body and swallowed up full of host cells, finally leaded to the host cell death.

在巨噬细胞内，军团菌破坏小泡传输，产生空泡，阻止吞噬体-溶酶体融合，阻止内涵体和溶酶体的杀菌作用，建立其独占的复制型吞噬体，以二***复制，产生大量的吞噬体，布满宿主细胞，导致宿主细胞死亡。

The susceptibility of the host to Fasciola spp. infection is associated with the host''s immune response.

宿主对片形吸虫感染的易感性与宿主的免疫应答有关。

The biologic assay validated that Allium porrum、Allium cepa、Vicia faba and Gomphrena globosa was better indicator host of LYSV、OYDV、GCLV and PVX respectively. Virus particles were observed in purified sap from infected garlic or infected indicator host.

明确了韭葱是LYSV很好的鉴别寄主和繁殖寄主，洋葱是OYDV很好的鉴别寄主和繁殖寄主，蚕豆是GCLV很好的鉴别寄主，千日红是PVX很好的鉴别寄主。

Las multiplied again in the hemocoel and then invaded other host tissues, including hemocytes, nervous tissue, fat body, trachea, and muscle. Eventually, Las invaded the salivary gland and the Las-infected psyllids were enabled to transmit Las to other host plants. Symptoms of serious pathogenesis occurred in the muscle tissue.

黄龙病菌必需先穿过中肠上皮细胞并於中肠细胞内进行增殖，接著进入血腔继续进行增殖，并逐渐移行至其他组织包括血球、神经、脂肪体、气管上皮细胞及肌肉等，最后抵达唾腺，届时柑橘木虱即具有传播黄龙病的能力。

After the NK gene from recombinant plasmid pUC19-NK was cloned on expression vector pBV220, it was transformed into host cell E. coli HB101. Recombinant plasmid pBV220-NK was extracted for identifying by analysis of restriction enzymes, PCR and sequencing. Studies on recombinant strain's growth and expression showed that heterogene have no distinct effect on host cell. The recombinant plasmid have excellent segregational stability but low structural stability. The results of kinetics of pBV220-NK expression in E.

将重组质粒pUC19-NK上的纳豆激酶基因成功克隆到表达载体pBV220上，并将之转入大肠杆菌HB101中，得到转纳豆激酶基因工程菌，提取重组质粒经单酶切、双酶切及PCR分析验证后，对重组菌的生长及表达进行一系列研究，结果表明：外源纳豆激酶基因的导入对宿主的生长没有明显的影响：重组质粒的稳定性实验表明：该质粒具有良好的分离稳定性，而结构稳定性较差。
