查询词典 maxillary

Although a lot of behavioral study of the insects have been investigated for their chemical sense ability, the maxillary palp of cockroach has never be investigated electrophysiologically.

其次，由于美洲蜚蠊下颚须末端腹面味觉毛的化学感受能力至今未见有电生理研究的工作报道。

The response of the sensillar field on the maxillary palp of the cockroach was studied for different stimulants such as four salts, three sugars, eighteen amino acids and bovine serum albumin . Analytical properties such as selectivity, sensitivity, repeatability, response time, lifetime, and dose-response relationship etc. were investigated.

主要探测了四种盐、三种糖、十八种游离氨基酸和牛血清白蛋白等刺激物质作用下美洲蜚蠊下颚须味觉毛的响应及其特点；并对这一生物传感器的分析特性诸如选择性、灵敏度、重现性、响应时间、寿命、和剂量响应关系等方面进行考察。

Although the intact-receptor based biosensors of the maxillary palp of cockroach Periplaneta Americana are not yet practical analytical devices at present. Yet, sensitive and selective responses to biomolecules involving amino acids and protein, as well as some simple substance such as salts and sugars have been firstly obtained. It is already evident that receptor based biosensors are enormously superior to isolated receptor biosensors in terms of response time and recovery times, thus, the intact receptor biosensor worth of further investigation and development.

总而言之，本论文首次从电生理信号上对美洲蜚蠊下颚须的化学响应进行研究，初步探讨了基于美洲蜚蠊下颚须的整合受体生物传感器的特性；发现了美洲蜚蠊下颚须能够整合其密集的感觉毛阵列对化学刺激的响应；得到了蜚蠊对氨基酸和蛋白质等生物分子以及简单物质如盐和糖等的敏感而具有选择性的响应信号，并发现了糖和蛋白质的特殊响应信号；表明了美洲蜚蠊下颚须是一种新型整合受体生物传感器的敏感材料，进一步深入地研究信号波形及其整合原理、探寻糖和蛋白质的特殊受体细胞等，对这一类型整合受体传感器的研究发展是很有意义的。

On the basis of the instrumentation to study intact-receptor based on maxillary palp of cockroach Periplaneta Americana, a thermoplate was designed for constant temperature control during the experiment and a new electrode holder was also designed for improving reproducibility.

依响应频率将氨基酸分成了三类：响应频率最高的第一类为天冬氨酸、谷氨酸、甘氨酸和脯氨酸，其次为第二类包括组氨酸、精氨酸和苯丙氨酸，第三类为没有响应信号的包括丙氨酸、色氨酸、酪氨酸和苏氨酸等。

Using scanning electronic microscopy, the microscopic characters, including stain, antenna, labial palp, maxillary palp, lima and tarsal pulvillus, of every individual on the sequence were observed. The relationship of microscopic characters among Anoplophora glabripennis, A.

利用扫描电镜对这12个体的斑纹、触角、下唇须、下颚须、前胸音锉及跗垫进行了超微结构的观察和比较，以探讨光肩星天牛、黄斑星天牛和"过渡类型"三者间超微形态特征的关系。

As a result, both the detection limit of the sensor decreased by 2～3 magnitudes and the signal magnitude increased about ten times than that of fly labellar single hairs. The sensitivity to many stimulants from simple molecules such as NaCl, KCl, sucrose, glycine, proline, glutamic acid and aspatic acid to macromolecule such as bovine surem albumin was lower than 10〓mol L〓. For this reason, the maxillary palp of cockroach is reveled as an important candidate for construction of a new type of intact-receptor biosensors.

这种协同作用导致下颚须感觉区对有些刺激物如NaCl，KCl，蔗糖，甘氨酸，脯氨酸，谷氨酸，天冬氨酸，牛血清白蛋白的响应阈值比一般单根感觉毛至少低2-3个数量级，达10〓molL〓以下；信号幅度提高约十倍，是一种新型的适合用作传感器的敏感材料。
