The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。

Hypothesizing that postmenopausal women might be particularly vulnerable to any adverse effects of HIV infection or on the skeleton, we initiated a longitudinal study to assess the prevalence of osteoporosis/osteopenia, determinants and etiology of low BMD and rates of bone loss in HIV+ postmenopausal Hispanic and African American women, who constitute the majority of new infections in women in the United States.

假设停经后女性可能特别容易发生HIV感染或是抗反转录病毒药物治疗对骨骼的不良反应，我们进行了一项纵向研究，以评估骨质疏松症/骨质低下的盛行率、以及HIV阳性停经后西班牙裔与非裔美国居民低BMD以及骨质流失的决定因子和病因学，这些人种构成美国新感染女性的绝大多数。

The TiSi2 reactants in the green compacts with 50% porosity were fully nitrified and the final products were composed of Si3N4, SiC and TiN.

压坯孔隙率为50％时，反应物TiSi2氮化充分，最终产物为Si3N4-SiC-TiN。

Then, PP-g-PVAc granule was saponified to PP-g-PVOH by heterogeneous saponification technique with NaOH/KOH as catalyst in alcohol dispersing medium. During our investigation, some methods to prepare PP-g-PVOH with high saponification percentage were explored.

The orthogonal experimental design was applied to investigate the effects of zirconia source Zr(NO34·5H2O, ZrOCl2·8H2O,precipitants and sulfating agent (sulfuric acid, ammonium sulfate) on the catalytic performance of the catalysts unde the most superior condition .The catalytic activity was tested in esterification of acetic acid with butanol .

在最优的条件下用正交设计法考察锆源（Zr(NO3)4·5H2O，ZrOCl2·8H2O）、沉淀剂和硫酸化试剂对催化剂性能的影响，并通过乙酸和正丁醇的酯化反应的酯化率检测所制备的SO4/ZrO2催化剂的催化效果。

Results show that acid value of carboxylic wood powder from alkaline hydrolysis is higher,but its yield is lower than that from acid hydrolysis. The adsorption capacity of carboxylic wood powder for basic pink dye increased with increase of the initial concentration of the adsorbate,and could be kept over 500mg/g after repeated use and regeneration for 4 times.

实验结果表明：（1）在适量引发剂（FeSO4 * 7H2O=1g）和适当温度（60℃）作用下，可得到较高接枝增量和接枝率的PANW；（2）在PANW的水解反应中，在碱性催化剂作用下，可得到羧基含量高的产物，但收率较低；而在酸性催化剂作用下，则得到羧基含量低的产物，但收率较高；（3）羧基木粉对阳离子型染料--碱性桃红的吸附容量与起始浓度有关，本实验中，羧基木粉对碱性桃红的吸附容量最高可达500mg/g，对Cu2+的吸附容量最高可达39mg/g；（4）经0.3mol/LHCl再生4次后，羧基木粉对碱性桃红的吸附容量保持在440mg/g以上，在含有多种金属离子的溶液中，羧基木粉优先吸附Fe3+等硬酸型离子。
