查询词典 convenience sampling

Factors influencing the tensile strength of polymerizer head sample were introduced,which included the sampling position,sampling direction,sampling quantity and the cross section shape of sample.

介绍了影响聚合釜封头试样拉伸性能的因素：取样部位、取样方向和取样数量及试样的横截面形状。

This sampler is mounted along the pipeline, and there is no need for elevation difference, thus no pressure head lose is caused. Because of the special structure of the sample spoon and perpendicular sampling to the slurry flow, the sampling is kept accurate and respresentative. Sampling time is adjustable between 5 minuets to 50 minuets. Photoelectric technology is applied to the electrical part, and complete safety protection circuit is prepared. Its control is rather simple, action sensible and safety reliable.

At first the current sampling values pass through virtual digital CVTs. And then the voltage and current sampling values are processed by a low pass filter. According to the instantaneous value of transmission line voltage, the current instantaneous values of shunt reactors and P equivalent circuit capacitance can be calculated. After removing these two kinds of current, sampling value differential protection based on all components and fault component can be applied.

由线路电压瞬时值分别实时计算出流入并联电抗器和流入线路Π型等值电路两侧电容的电流瞬时值，再从线路每侧电流除去这两部分电流，用得到的新电流瞬时值作常规采样值差动和故障分量采样值差动保护计算。

The outstanding functions of this multi-fucntional wheelchair is that the hight of the seat could be adjusted at will. So that it may stretch users' operating space and make up users' physical handicap.It could alleviate the workload of paramedics as well. It is more advanced than previous products.This wheelchair could be driven by hand or electricity. Thus, the shortage of physical force of old and handicapped people could be solved. At the same time, users could still operate this wheelchair when batteries run out. Such design eliminate worries of users on a long-distance trip.In addition, a super big storage box on tail of wheelchair brings great convenience to users. backrest can be adjusted multi-anglely. Adjusted feet board increases cosiness. A small table of this wheelchair really brings extraordinary convenience when users want to read, write or do other activities.

本设计的多功能轮椅最突出的一个功能就是座位的高度可以根据使用者的需求随意进行调节，这样就可以大大扩展使用者的操作空间，补充了使用者在身体上的缺陷，也可以减轻照顾人员的工作负担，比起以前的产品有了较明显的改进；其他功能还有轮椅的手动电动两种驱动方式，这样可以解决老年人和残疾人在体力上存在的问题，同时在外出时遇上没电的情况也不至于显得无能无力，消除了使使用者在长途奔波时的顾虑；此外位于轮椅尾部的超大储物筐，给使用者携带物品带来了极大的方便，靠背的多角度调节，脚踏板的高度调节大大增加了使用者的使用舒适度，轮椅上小桌的设计给使用者读书，写字，进行其他活动带来了极大的方便。

The "Interaction and Anxiousness Scale","The convenience store's Employees Social Skills Scale","Job Satisfaction Scale", and "The convenience store's Employees Job Performance Scale " were introduced as the research measurement to collect the necessary data. Data were analyzed by descriptive statistics, t -test, one-way ANOVA, canonical correlation, and structural equation modeling.
