儿童肚子痛是一种较为常见的疾病，有的是由蛔虫引起的，如肠蛔虫症、胆道蛔虫症等；有的肚子痛则可能是由某些疾病引起的，如阑尾炎、胰腺炎以及肠道的感染和消化不良等。

A new ZVS-ZCS ARCPI (auxiliary resonant- commutated pole inverter) is proposed to solve the problems, such as extra loss from auxiliary circuit, variable commutation duration, and delicate reliability etc., which exist in other ARCPIs.

辅助谐振换流逆变器拓扑结构中存在着诸如由辅助换流回路损耗引起的转换效率低、由负荷电流变化引起的变辅助换流周期和稳定性差等问题，为此提出了一种基于变压器辅助换流的新型ZVS-ZCS逆变器。

The dips deriving from transformer energizing can be distinguished via ST contour easily, and the dips caused by faults or motor inductions are classified using corrected first central moment and phase angle curve of amplitude envelope vectors from S-matrix.

利用S变换时频等值线图可以容易地识别由变压器激磁引起的电压凹陷；对于由各种故障和感应电机启动引起的凹陷，通过求取S矩阵幅值包络向量的修正一阶中心矩和相位变化曲线实现了分类。

A parasitic disease of many animals, including cattle, swine, sheep, dogs, cats, and poultry, but rarely of human beings, resulting from infestation of the alimentary canal by protozoans of the order Coccidia.

球杆菌许多动物，包括牛、猪、羊、狗、猫与家禽的由寄生虫引起的病，但人类罕见，由球孢子菌的原生动物经由营养管道的感染而引起

Demand-pull inflation is caused by excess demand in the economy, while cost-push inflation is caused by increased costs of production.

需求拉动型通货膨胀(demand-pull inflation)是由经济中的过度需求引起，而成本推动型通货膨胀(cost-push inflation)则由生产成本上升引起。

It is shown that the friction force and bulkhead thrust are the main factors of shield thrust setting, while the friction between the cutterhead and soil is the main factors of cutterhead torque setting. Friction force between shield and soil would make front soil of shield upheave, and subsidence of surface soil is induced by ground loss when the friction force between the cutterhead and soil results in the surface settlement asymmetrical distribution.

通过计算发现，盾构施工中盾壳摩擦和正面推力是盾构推力设置的主要因素，而刀盘与土体摩擦是刀盘扭矩设置的主要因素，盾构前方土体隆起主要由盾壳摩擦引起，刀盘摩擦作用主要引起地表沉降的非对称分布，地表沉降主要由盾尾空隙产生。

The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

The air flow excitation force of leaf peak clearance evocable by impeller eccentricity is the important part of the air flow excitation force, so the research of it is very important too.

而由叶轮偏心引起的叶顶间隙气流激振是气流激振的一个重要方面，因此，加强透平机械中由叶轮偏心引起的叶顶间隙气流激振的研究也显得非常重要。

This current is known as the input offset current, and it is caused by bias currents of active devices as well as by leakage currents through insulators within the INSTRUMENT .

这个电流就是输入失调电流，它可能是由有源设备的偏置电流引起的，也可能是由仪器内的绝缘体泄漏电流引起的。

It is commonly due to impaction of a gallstone within the neck of the gall bladder, leading to inspissation of bile, bile stasis, and infection by gut organisms.

胆囊炎就是指胆囊炎症，通常由胆结石嵌顿在胆囊颈部引起的，这回导致胆汁浓缩和胆汁郁积，并由大肠微生物引起感染。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
