A series combined test method tests were performed to determine the liquid-plastic limits of different samples of fine grained soil and silty sand. The result showed that the loglog relationship between the depth of penetration of fall cone and the water content of some samples were clearly not linear, and the liquid-plastic limit could not be obtained according to the linear relation. Effective test data could not be measured within the three arranges of water contents proposed by the present standards. The dependability was necessary to discuss about the liquid-plastic limit test results obtained from three arranges.

采用液、塑限联合测定法针对部分细粒土和粉砂进行液、塑限测定时，发现对于部分细粒土在双对数坐标上圆锥下沉深度与含水率之间的关系并非线性关系，无法依据线性关系确定液、塑限：采用规程建议的三个含水率范围有时根本无法获得有效试验数据；采用规程建议的三个含水率范围确定得到土的液、塑限试验结果的可靠性有待商榷；采用直线段试验数据确定的液、塑限进行分类可能出现相互矛盾甚至错误的结果。

The probing behaviors of the tea green leafhopper, Empoasca vitis Gothe, on nine tea cultivars were studied by videotext Direct Current-Electrical Penetration Graph, i. e. DC-EPG. Following seven types of waveforms produced by the leafhopper stylet probing were determined: A, stylet pathway formation; S, salivation when stylets pierce into and stay in phloem; C, active ingestion before stylets reach phloem; E and F, passive ingestion in phloem; R, the insect resting with its stylet inserted into the leaf tissue and NP, not probing.

应用可视DC-EPG方法研究了假眼小绿叶蝉在9个品种茶苗上的口针刺探行为，共发现并初步确定了7种主要波型，即A波、S波、C波、E波、F波和R波、以及非刺探波NP波。A波为刺探波，S波为口针向韧皮部刺探和进入韧皮部中的分泌唾液波，C波为口针到达韧皮部之前的主动取食波，E波和F波为口针在韧皮部中吸收波，R波为取食间歇波。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
