TOY RECALLS——IS CHINA THE PROBLEM？
Hari. Bapuji Paul W. Beamish
China exports about 20 billion toys per year and they are the second most commonly imported item by U.S. and Canada. It is estimated that about 10,000 factories in China manufacture toys for export. Considering this mutual dependence, it is important that the problems resulting in recalls are addressed carefully.
Although the largest portion of recalls by Mattel involved design flaws, the CEO of Mattel blamed the Chinese manufacturers by saying that the problem resulted ‘in this case （because） one of our
manufacturers did not follow the rules’. Several analysts too blamed the Chinese manufacturers. By placing blame where it did not belong, there is a danger of losing the opportunity to learn from the errors that have occurred. The first step to learn from errors is to know why and where the error occurred. Further, the most critical step in preventing the recurrence of errors is to find out what and who can prevent it.

玩具召回——是中国的问题吗？
哈里·巴普基 保罗·比密什
中国每年大约出口20亿美元的玩具，最常见是从美国和加拿大进口项目。据估计，中国大约有10000家玩具制造工厂从事玩具出口。考虑到这种相互依存，在召回时谨慎处理是很重要的。
尽管绝大部分美泰的玩具召回涉及设计缺陷，但是，美泰公司的首席执行官指责中国制造商说，导致这种问题的原因“是因为我们的一些制造商不遵守规则”。一些分析师也指责中国制造商。把责任归咎于不存在错误的地方是危险的行为，这将使得我们丧失从继有的错误中吸取教训的机会。第一步是要从错误中学习知道为什么发生错误和哪里发生了错误。此外，防止错误的再次发生最关键的一步是要找出什么以及谁可以阻止它。

Bolt Supporting of Large-Span Soft Rockway in
Shaqu Colliery
Abstract The instability of trapezoidal I-steel support is analysed for the compound roof of main coal seam in Shaqu Colliery, and the mechanism of bolt supporting is studied. A scheme of bolt supporting has been given and put into practice,remarkable technical and economic benefits have been got.
Key words :large-span,compound roof, bolt supporting, mechanism
1.Introduction
In shaqu colliery a large coal mine mining rare coking coal in China, most roadways are laid out in main coal seam
roof of coal seam .The soft compound ,which is composed of mudstone and coal seam
contains aboundant beddings and joints. The strength of the roof is so low that its uniaxial-saturated compressive strength is only 10.7 Mpa.RQD value of coal seam and is zero ,and that of mudstone is lower than 10%. There is clay minerals in mudstone, main compositions are interbedded strata of illite and montmorillonite which will swell when soaked by water, The span of preperation roadways and gateways is wider than 4m, and that of some main roadways is over 5m. In shaqu colliery , preperation roadways and gateways were supported by trapezoidal I-steel support, the beams of which were bent and damaged, and the roadways were destroyed seriously within a short period just after excavated. Roof
controlling of Large-Span Soft Rockways in the coal seam became the key to the production and construction of shaqu colliery.
2.supporting status and instability analysis of trapezoidal I-steel supports
trapezoidal I-steel supports were used in drawing roadways,which roof span is 4.0m, floor span is 4.9m, and hight 2.95m and spacing 0.5m. Initial resistance of the supports was almost zero because it was difficult to the support beams contact the roof, even if with high quality of installation. The trapezoidal I-steel supports would not carry load until the displacement of surrounding rock excceded 80-100 mm because the supports increased very slowly. Therefore, right after excavation, the roof would bend and subside severly. Eight hours after excavation, the roof strata would break completely, and then form rock cavity. The weight of caving rock would act on the beams of supports, which forms loose rock pressure.
By calculating, the ultimate load-bearing capacity is smaller than roof pressure whether it is uniformal or concentrated, Based on the in-situ observation, inflection value of most roof reached 200-300mm. When paired supports were used, paired beams were still bent and damaged; then midprops were added, they were also destroyed. Many roof beams were stabilized only if 2-3 props had been added. The supports were damaged completely, and most of them could not be reused. The part
section of roadways had become inverted trapezoid, and the available section was far smaller than the designed section. Part of roadways was out of use because it was in the danger of serious caving.
3.Mechanism of bolt supporting
Its mechanism is to make full use of the self-load-bearing capacity of surrounding rock by bolting, and then make the surrounding rock stabilize by itself. The stability of surrounding rock depends on the equilibrium status of ground pressure, self-load-bearing capacity of surrounding rock and anchoring force of bolts. Ground pressure is to make surrounding rock deform and break; self-load-bearing capacity is the main factor to stablize surrounding rock. Anchoring force of bolts can not change the equilibrium status of the three because it is very small, compared with ground pressure and self-load-bearing capacity. And its function is to change the decreasing regularity of self-load-bearing capacity versus the deformation of surrounding rock, and balance self-load-bearing capacity against ground pressure early.
Roof pressure is the pressure acting on the roof beams when I-steel supports are used to control the roof. When roof is supported by bolts, the roof pressure change to be the pressure acting on the rock within the bolting range because this part of rock is change into self-bearing body. According to the characteristics of the roof of coal seams
can be divided into six substrata. , bolts strata
When the value of roof subsidence is zero, roof pressure is in-situ stress; then roof pressure decreases with the increase of roof subsidence. The variation of roof pressure is analyzed by FLAC, The results are shown as curve 1 in Fig.1. Wheoof subsidence reaches 19 mm, the first roof substratum begins to bearing tensile stress, then losts self-load-bearing capacity, and roof pressure decreases to 0.67Mpa. When roof subsidence reaches 40 mm, the second substratum loses self-load-bearing capacity, and roof pressure decreases to 0.16Mpa. When roof subsidence reaches 100 mm, the fourth substratum loses self-load-bearing capacity, and roof pressure decreases to0.08Mpa. In the initial stage of roof subsidence, roof pressure decreases rapidly, and in the later stage of roof subsidence, roof pressure decreases slowly and then has an increasing trend.
The self-load-bearing capacity of the roof without bolting is calculated upon the theory of laminated beam, the result are shown as curve 2 in Fig.1. When roof subsidence is zero, the self-load-bearing capacity is at its utmost value 0.0625Mpa; when roof subsidence is 100mm,roof strata have broken, most of self-load-bearing capacity has lost, and the residual self-load-bearing capacity is only 0.0375Mpa.The self-load-bearing capacity of the roof with bolting is calculated upon the theory of combined beam, the result are shown as curve 3 in Fig.1. When roof subsidence is zero, the self-load-bearing capacity is at its utmost
value 0.4Mpa; when the roof subsidence reaches 40mm the self-load-bearing capacity decreases to 0.225Mpa,and when roof subsidence reaches 100mm, the self-load-bearing capacity decreases to 0.1Mpa .
As shown in Fin. 1, the self-load-bearing capacity of roof strata without bolting is lower than roof pressure during the whole course of roof subsiding, so roof strata cave inevitably. When bolted, roof strata is changed from laminated beam into combined beam ,and the selr-load-bearing capacity increases markedly. When roof subsidence reaches 44mm, the self-load-bearing capacity exceeds roof pressure, then roof strata stabilized by itself.
4 Anchoring technology
Based on the above study of bolting mechanism, large setting resistance, high speed of resistance and high final resistance are the key technology to the large-spon soft rock roadway before roof strata detaching, which includes: (1)to improve the setting resistance increasing and achieve high speed of resistance increasing, to make the real working properties of bolts coordinate self-load-bearing properties of roof strata , which enables to make full use of the self-load-bearing capacity of roof strata; (2)to raise bolting reliability, and solve the difficult problems that anchoring force between bolts and soft rock is small and easy to lose.
4.1 Bloting scheme
篇三：英语3000字论文
From mid-2005 to the present, many large international Clothing Buyers to shift their business out of Sri Lanka, into more cheap manufacturing destination. During this time, in seven provinces to close 75 factories, including 24 factories in the past 6 months to close. The survey was conducted in February 2009, is a private advisory body RoyDawson conducted.
The survey found that many of the major Sri Lankan Clothing Foreign buyers in the past three years, closed their offices in Sri Lanka, their manufacturing orders to other countries.
Procurement office in Sri Lanka Apparel Association registered about 50 major international apparel sourcing units, 12 units in the past three years, closed their offices in Sri Lanka. The major shift procurement office in Singapore, India and Pakistan. Production mainly to India, Bangladesh and Vietnam.
So far, about 20 foreign buyers no longer a stable operation in Sri Lanka.
A major reason for their transfer business in Sri Lanka's production costs are relatively high and unstable security situation is also a Print . For example, buyers find it difficult to dispatch technical personnel to local factories for regular factory monitoring, which is at the security concerns.
The survey also found that the seven provinces in the investigation of the 75 garment factories in mid-2005 and 2009, only in the past 6 months, there are 24 factories closed. These factories are mainly located in Katunayake, Biyagama, Koggala and SeethawakaPura the free trade zone. Some factories registered in the Investment Authority, part of the plant in the Ministry of Industrial Development Textile Office. In addition, these garment factories closed due to foreign exchange losses to combat unemployment and other related industries. This includes embroidery factory, garments washing plants, manufacturing plants fold, label manufacturing plant, silk manufacturing units Plastic Rack and the polyethylene bag manufacturing units, transport service providers, shipping agency, freight Proxy Agencies, customs clearing technological transformation, Food Providers, sub-contractors to provide services, such as fabric cutting, ironing and packing.
The survey showed that in 1980 and 2004, in Sri Lanka has 650 large, medium and small-scale garment manufacturing plant, to increase the direct employment of 45 million people, 10 million people with indirect
employment. However, since 2005, the termination of multi-fiber agreement and the end of export quotas, Sri Lanka's garment industry stable contraction.
This is mainly due to Sri Lanka's apparel manufacturing with other Asian countries compared to the higher cost of production. The current global recession has also hit the apparel industry in the past 6 months, increase the frequency of plant closures.
