Abstract］ Objective: The purpose of the study is to examine the effect of Carnoy's solution and trichloroacetic acid on maxillary sinus mucosal regeneration and bone remodeling.

摘要］ 目的：本实验采用Carnoy液和三氯醋酸涂布兔上颌窦粘膜及窦腔骨壁，研究两种药液对这些组织的损伤特性以及对粘膜再生修复和骨改建过程的影响。

The intermediate product was trichloromethyl benzyl alcohols that further reacted with acetic acid to prepare the crystal rose.

结晶玫瑰化学名为醋酸三氯甲基苄酯，是花香型香精优良的定香剂[1]，它广泛应用于人们的生活和生产中。

Both iron atoms of the binuclear unit are bridged by one oxy atom and two acetate groups. Each iron atom is also bound to facially - coordinating tridentate IDB ligand with the aliphatic nitrogen donor situated trans to theμ- oxy atom. Each iron centers is in a distorted octahedral symmetry.

每个双核单元的两个铁原子均通过一个氧原子和两个醋酸根连接，每个铁原子同时还与位于桥氧原子对位的三齿配体IDB重脂肪链上氮原子相结合，每个铁中心为一变形八面体结构。

This paper reports the experiment on the heat storage-release property of the trihydrate sodium acetate system.

报道了三水合醋酸钠体系蓄放热性能的实验研究。

A new heat storage material (CH3COONa·3H2O) with a phase change temperature of 55℃ and a sub-cooling temperature of less than 2℃ was developed. This sodium acetate trihydrate based material was obtained by a number of experiments for selecting proper nucleation catalysts and suspension mediums.

以三水醋酸钠(CH3COONa·3H2O)为蓄热基质，通过大量实验，遴选合适的抗沉淀剂和成核剂，配成相变温度约55℃、过冷度小于2℃的蓄热材料。

Three organochlorine pesticides -endrin, dieldrin, and p,p'-DDT-were used as target compounds to test the hypothesis that triolein embedded cellulose acetate membrane only extracts freely dissolved hydrophobic organic compounds. The effect of dissolved organic carbon on the bioavailability of the OCPs was also examined through accumulation study with TECAM and Japanese medaka.

以异狄氏剂、狄氏剂和p，p'-滴滴涕3种持久性有机氯农药为研究对象，通过室内模拟实验，验证了三油酸甘油脂-醋酸纤维素复合膜富集水中自由溶解态疏水性有机物的假设，研究了水中溶解性有机碳对TECAM富集3种有机氯农药的影响，并与相同暴露条件下日本青鳉鱼的富集结果进行了比较。

A new colorimetric chemosensor 1 based on a tripodal benzaldehydic-phenylhydrazone selectively sensing acetate ion has been synthesized.

本文合成了一个新的基于三脚架苯甲醛苯腙的能够选择地检测醋酸根离子的比色化学传感器1。

A salt of tungstic acid .

一种由砷酸铜和醋酸铜形成的有毒复盐。

ResultsESC(the extract of Solidago canadensis L.) markedly prolonged the writhing latent period and decreased the times of writhing of mice induced by ip acetic acid, while it had no obvious effect on the pain threshold value in hot plate test. ESC significantly prolonged the tussive latent period of mice, decreased the tussive times and increased phenolsulfonphthalein excretion quantity of trachea of mice. ESC was nontoxic according to the acute toxicity test.

结果首次对国产加拿大一枝黄花进行了体内药理作用研究，发现加拿大一枝黄花提取物能显著延长醋酸致小鼠扭体潜伏期，减少扭体次数；但未明显提高热板法实验小鼠的痛阈值；能显著抑制浓氨水所致小鼠咳嗽潜伏期和咳嗽次数；显著增加小鼠气管的酚红排泌量；急性毒性实验表明加拿大一枝黄花提取物无明显毒性，既不引起小鼠死亡也不影响小鼠体重正常增加。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
