ABSTRACT
From 1997 to March 2000, as technology stocks rose more than five-fold, institutions
bought more new technology supply than individuals. Among institutions, hedge
funds were the most aggressive investors, but independent investment advisors and
mutual funds (net of flows) actively invested the most capital in the technology sector.
The technology stock reversal inMarch 2000 was accompanied by a broad sell-off from
institutional investors but accelerated buying by individuals, particularly discount
brokerage clients. Overall, our evidence supports the bubble model of Abreu and
Brunnermeier (2003), in which rational arbitrageurs fail to trade against bubbles
until a coordinated selling effort occurs.

Standard Test Method for

Conducting Friction Tests of Piston Ring and Cylinder Liner Materials Under Lubricated Conditions

نسخه 2011

10 صفحه

Scope
1.1 This test method covers procedures for conducting
laboratory bench-scale friction tests of materials, coatings, and
surface treatments intended for use in piston rings and cylinder
liners in diesel or spark-ignition engines. The goal of this
procedure is to provide a means for preliminary, cost-effective
screening or evaluation of candidate ring and liner materials. A
reciprocating sliding arrangement is used to simulate the
contact that occurs between a piston ring and its mating liner
near the top-dead-center position in the cylinder where liquid
lubrication is least effective, and most wear is known to occur.
Special attention is paid to specimen alignment, running-in,
and lubricant condition.
1.2 This test method does not purport to simulate all aspects
of a fired engine’s operating environment, but is intended to
serve as a means for preliminary screening for assessing the
frictional characteristics of candidate piston ring and liner
material combinations in the presence of fluids that behave as
use-conditioned engine oils. Therefore, it is beyond the scope
of this test method to describe how one might establish
correlations between the described test results and the frictional
characteristics of rings and cylinder bore materials for specific
engine designs or operating conditions.
1.3 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.4 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
