【正文】 5). With the extension of incubation time， the hole became bigger and did not appear again and kenaf fiber became shorter at the end of incubation. This indicates that the hole may be the result of enzyme action to break down PLA on the surface， and that P.5 shows SEM photos of one microfiber of PLA/kenaf before and after degradation. Degradation appeared clearly on the surface. The figure also clearly shows that PLA was fully impregnated into interfibrillar voids (control)。 also evident were fragility， and loss of weight and flexural strength during degradation by P.ostreatus has the ability to degrade PLA/kenaf posite was indicated by significant changes on the surface， which became pale whitish， and by progressive fragmentation. Thus there are more evident forms for PLA/kenaf posite after 1， 2， 3， and 6 months39。ostreatus. This result shows a tendency similar to that of the weight loss of PLA/kenaf posite.Visual observation of the physical alteration of PLA/kenaf posite after and before degradation is shown in Fig.ostreatus. This suggests that crosslinking bonds between the matrix resin (PLA) and kenaf fiber were cleaved by P.) after 2， 3， and 6 months， respectively， of the original strength. This was caused by the action of3. The flexural strength of the posite decreased after 1 month by 58% and continued to decrease to 69%， 72%， and 84% (P Yussuf et Lee et3 shows that the flexural strength of PLA/kenaf decreased to 43ostreatus) growth. This approach also has undesirable effects on the mechanical properties and dimensional stability of the posite (Akil etal.， 2010)， and 254al.， 2009)， 90MPa. Other studies have reported the flexural strength of PLA/kenaf posite as 52s modulus of ostreatus was the dominant factor in the degradation of the PLA/kenaf posite.Nishino etal.， 2010). The results indicate that microbial and enzymatic activities are crucial to the degradation. Weight loss of PLA/kenaf posite also occurred in the control (Fig.ostreatus at 6 months (48%) was higher than that for the control (18%). This indicates that P.ostreatus degraded the posite as shown by the increase in the weight loss of samples during the extension of incubation time. The weight loss was fastest after 3 months39。ostreatus， which is used for several purposes in the field of bioremediation.The residual weight percentage of the PLA/kenaf posite is displayed in Fig. Yussuf et70% vol.). Previous researchers have conducted biodegradability tests for this material using enzymatic controlled posting and natural soil burial tests (Ohkita and Lee， 2006。cm?1 per sample.3. Results and discussion. Weight lossPolylactic acid/kenaf posites are made from a bination of PLA as the matrix resin and kenaf fiber as reinforcement (fiber contentcm?1–4000176。mM MnSO4 (Wariishi etmin. The enzymatic activity in the crude supernatant was investigated using a Shimadzu UV1600 spectrophotometer. Manganese peroxidase activity was assayed using 50ml of water and homogenized at 10，000ostreatus mycelia immobilized with Caalginate beads to degrade PLA/kenaf posite. The production of enzymes and characteristics of the degradation process were also investigated.The enzymatic activity was observed for 1， 2， 3， and 6 months. The PLA/kenaf sample (5al.， 2004。al.， 2006). Fungi have advantages over bacteria in being highly plastic， highly tolerant， totipotent (regenerating not only via spores but also from hyphal fragments)， and able to access or penetrate xenobiotics through hyphal elongation (Cerniglia and Sutherland， 2001。al.， 2004。 Kang and Oulman， 1996。μm in width (Akil etal.， 2003). Kenaf also has cellulose， hemicellulose， and lignin –m in height and – therefore kenaf (or some other ponents such as bamboo， grass， palm oil， or straw (Pamula etal.， 2011). Besides the automobile industry， lignocellulosic fiber posites are also used for building and construction as panels， ceilings， and partition boards (Hariharan and Khalil， 2005).The PLA/kenaf posite is a bioposite made from a bination of kenaf fiber (Hibiscus cannabinus) and PLA with a ratio of 70:30。 therefore the microstructure of each， especially the association between the polymer and fiber ponent， will affect its ability to be degraded (Pamula etal.， 2003).Bioposites are defined as materials made with a bination of natural fibers and biodegradable or nonbiodegradable polymers， which， if derived from natural fibers and biodegradable plastics， are likely to be more ecofriendly (Shinoj etal.，2008) and accounts for about 10–11% of total waste in the world (Fukushima et同時(shí)也要感謝我們解放路支行的各位同事以及領(lǐng)導(dǎo)，感謝你們?cè)诠ぷ髦袑?duì)我的關(guān)照以及教導(dǎo)，非常感謝你們能夠全心全意的教導(dǎo)我，讓我能夠在做大堂這方面的工作的能力飛速成長(zhǎng)，真心的非常感謝我的無(wú)私的同事以及領(lǐng)導(dǎo)。綠色的標(biāo)志，象征著郵儲(chǔ)銀行的陽(yáng)光，散發(fā)著光明與活力；同時(shí)在內(nèi)涵上，秉持著穩(wěn)健踏實(shí)的一貫經(jīng)營(yíng)風(fēng)格，蘊(yùn)含創(chuàng)新突破的經(jīng)營(yíng)魄力。在這次實(shí)習(xí)過(guò)程中，我深刻體會(huì)到，走出校門(mén)，只是萬(wàn)里長(zhǎng)征的第一步，我們?cè)诠ぷ鹘?jīng)驗(yàn)，社會(huì)歷練，人際交往上體現(xiàn)出來(lái)的稚嫩，在這一次的實(shí)習(xí)中完全表露出來(lái)，而且我們所缺乏的還不僅僅如此，所以在以后的生活和工作中，我要不斷的充實(shí)和豐富自己，不放棄任何能夠鍛煉自己的機(jī)會(huì)，使自己能迅速的成長(zhǎng)為一名優(yōu)秀的商務(wù)人士。 在這次實(shí)習(xí)生活中，我不僅在工作能力上得到了極大的提升，同時(shí)，我的為人處事方面也變得更加圓潤(rùn)，在短短的三個(gè)月中，我就與行內(nèi)的兄弟姐妹們處的如同一家人。熟練掌握好本專業(yè)的知識(shí)。通過(guò)實(shí)習(xí)我發(fā)現(xiàn)大堂經(jīng)理是門(mén)實(shí)踐性很強(qiáng)的專業(yè)，它不光要求我們有扎實(shí)的理論知識(shí)而且必須具有很強(qiáng)的動(dòng)手操作能力，更重要的是學(xué)會(huì)如何與人溝通，怎么建立人際關(guān)系，這些是課本中學(xué)不到的，只有融入社會(huì)的大舞臺(tái)并不斷的歷練才能得到提高，還有加強(qiáng)各方面素質(zhì)的提高。在這段日子里，我也鍛煉了我的交際能力，提升了我的外交手段，鍛煉了我的口才，升華了我的公關(guān)能力，以及應(yīng)變能力，同時(shí)也學(xué)到了一些危機(jī)公關(guān)的知識(shí)。5. 實(shí)習(xí)期工作總結(jié)和收獲通過(guò)這次的實(shí)習(xí)工作，我學(xué)習(xí)到了很多作為一名大堂經(jīng)理所應(yīng)該具備的條件以及素質(zhì)?；氐郊抑幸院螅乙恢痹谒伎嘉医裉斓耐扑]介紹的每一個(gè)環(huán)節(jié)，把其中的不足補(bǔ)全，同時(shí)針對(duì)各類客戶種群，研究出不同的說(shuō)辭，向他們介紹我們的活動(dòng)并鼓勵(lì)其參加進(jìn)來(lái)。首先你得要有一顆堅(jiān)強(qiáng)的心，因?yàn)椴皇敲總€(gè)客戶都會(huì)聽(tīng)你在那里為他介紹這項(xiàng)活動(dòng)是什么，也不是每個(gè)客戶都會(huì)參加到你的活動(dòng)中來(lái)。在經(jīng)過(guò)經(jīng)理給我講解了這項(xiàng)活動(dòng)的中心思想后，我也查閱了如何去做這類活動(dòng)的方案，開(kāi)始了我個(gè)人的第一次全權(quán)執(zhí)行銀行內(nèi)部的大型活動(dòng)。在學(xué)習(xí)了這些技能以后，我已經(jīng)可以一個(gè)人完全擔(dān)當(dāng)起大堂經(jīng)理所有的工作內(nèi)容，并與客戶以及各柜柜員相處融洽。柜員：8名 宗柜：2名大堂經(jīng)理：2名 客戶經(jīng)理：2名行長(zhǎng)：1名四、 實(shí)習(xí)過(guò)程 （1）了解過(guò)程在剛到銀行的時(shí)候，我是跟隨的一名大堂經(jīng)理學(xué)習(xí)作為一名大堂所應(yīng)該掌握的一些知識(shí)和技能。三、 實(shí)習(xí)環(huán)境在2014年1月份，我開(kāi)始了我的校外實(shí)習(xí)工作，我來(lái)到了中國(guó)郵政儲(chǔ)蓄銀行山西省分行太原市建設(shè)南路支行，開(kāi)始了我為期3個(gè)多月的大堂經(jīng)理的實(shí)習(xí)生活。中國(guó)郵政儲(chǔ)蓄銀行承繼原國(guó)家郵政局、中國(guó)郵政集團(tuán)公司經(jīng)營(yíng)的郵政金融業(yè)務(wù)及因此而形成的資產(chǎn)和負(fù)債，并將繼續(xù)從事原經(jīng)營(yíng)范圍和業(yè)務(wù)許可文件批準(zhǔn)、核準(zhǔn)的業(yè)務(wù)。它可從谷物中取得，其制品廢棄后在土壤或海水中經(jīng)微生物作用可分解為二氧化碳和水，燃燒時(shí)，不會(huì)散發(fā)毒氣，不會(huì)造成污染，是一種完全自然循環(huán)、可持續(xù)發(fā)展的綠色環(huán)保生態(tài)纖維。以石油為原料制造合成纖維的生產(chǎn)過(guò)程所排放的二氧化碳造成嚴(yán)重的大氣污染和溫室效應(yīng)，以及世界范圍的原油消耗量擴(kuò)大，原始自然資源的嚴(yán)重減少。在自然界聚乳酸(PLA)能在微生物、水、酸、堿的作用
