Spontaneous discharges of action potentials of neuromuscular preparations in the leg and fore- or mid-gut of the Colorado potato beetle, Leptinotarsa decemlineata were recorded in situ under the treatment of oral injection of Cry3A toxin and permethrin insecticide.

对Cry3A毒素和氯菊酯杀虫剂经口注射处理的马铃薯甲虫的前肠、中肠和腿节样本的神经肌肉自发动作电位发射进行了记录。

Spontaneous discharges of action potentials of neuromuscular preparations in the leg and fore-of mid-gut of the Colorado potato beetle, Leptinotarsa decemlineata were recorded in situ under the treatment of oral injection of Cry3A toxin and permethrin insecticide.

对Cry3A毒素和氯菊酯杀虫剂经口注射处理的马铃薯甲虫的前肠、中肠和腿节样本的神经肌肉自发动作电位发射进行了记录。

The digestive tract was distinctively divided into buccopharyngeal cavity, esophagus, stomach, anterior intestine and posterior intestine at 1-2 days after hatching coinciding with the time of first feeding. The stomach was divided into cardiac, fundic and pyloric regions. The gall bladder was obvious.

孵出后1-2 d的仔鱼，消化系统已发育较完备，消化道分化为口咽腔、食道、胃、前肠和后肠，胃分化为贲门部、基底部和幽门部，胆囊明显，仔鱼开口摄食而进入混合营养阶段。

Gastric glands distributed in fundic regions at 5-8 DAH. At this stage, supranuclear vacuoles occurred in the anterior intestine and eosinophilic granules occurred in the posterior intestine. The volume of the liver increased. Zymogen granules were seen in the exocrine pancreas and the langerhans was obvious. From 21 DAH to 33 DAH, the digestive system developed to be perfect.

孵出后5-8 d的仔鱼，胃基底部的粘膜上皮下出现胃腺，前肠粘膜层中出现核上空泡，后肠粘膜层中出现嗜曙红颗粒，肝脏体积增大，在胰脏的腺泡中出现大量的嗜酸性酶原颗粒，胰岛明显。

Carpio hadthe highest frequency and were found only in the anterior segment of foregut.

However, not all herbivores have digestive systems that maximise fibre digestibility; only ruminants, camelids and very large hindgut fermenters achieve this.

对比而言，许多其它的食草动物，如前肠发酵的有袋类和小型的后肠发酵动物如兔子、田鼠和负鼠等，它们具备可以使植物纤维消化效率最大的消化系统，可以在食物中的纤维素含量非常高的情况下仍能处理大量的食物。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
