Dr Michael Ayliffe from the CSIRO says the secret to rust resistance might be found in rice."Rice doesn't get infected by any rust pathogens which makes it very atypical in that sense," he said."So we're trying to work out what are the genes responsible for this resistance."The bigger picture would be to see if we can transfer them to wheat and see if they can provide a level of resistance to wheat stem rust.

联邦科学与工业研究组织的艾立夫博士表示抗锈病的机理很可能会在水稻中发现，水稻的特殊之处在于它不会被任何锈病抗原感染，所以他们正在竭力在水稻上寻找抗锈病基因，更关键的是看看能否把他们转移到小麦上并能产生一定的抗性。

Ug99 could be called a superior virulent race to widely-used and Sr31-carrying Chinese wheat cultivars or stem rust resistant sources.The number of virulent genes contained in Ug99 was more than the total carried in all Chinese stem rust races.For instance,the virulence of Sr5,Sr9e or Sr11 was the typical races.However,besides the virulence of Sr5,Sr9e and Sr11,Ug99 contains additional virulence of Sr21,Sr31and Sr38,which have never been found in Chinese stem rust races.

Ug99堪称我国的超毒小种，我国最典型的秆锈菌小种只能分别克服或Sr5或Sr9 e或Sr11单基因抗性，而Ug99不仅具有Sr5、Sr9 e、Sr11的联合毒力，而且还具有Sr21、Sr31、Sr38的联合毒力，而我国从未有小种能克服后者的抗性。1B/1L(含Sr31)易位系曾是我国使用的重要秆锈抗源，必对Ug99高度脆弱，我国118份小麦品种在KARI的测定结果表明，高感品种频率98.3%。

In addition, there are two strands of the head is also black, and are rust, rust can be seen because of lead wire resistance increases, resulting in the signal can not be smooth, telephone through the audio signal, the low band signal can also only phone, there is always the voice of flap, and the use of the ADSL band signal is relatively high, head through the rust on it is very difficult, leading to slow or stop signal transmission.

此外有两处绞合的线头处也发黑了，都是锈，可见正是因为导线生锈导致电阻增大，导致信号不能畅通，电话通过的音频信号，频带低，信号还能通过，只是电话里老是有啪啪的声音，而ADSL的信号使用的频带比较高，线头生锈了就很难通过，导致信号传输变慢或者断流。

At the same W/C condition, ocean-sand (standard and non-standard) is mixed, non-standard ocean-sand shall have more compressive strength than standard ocean-sand about 10%, Add slag additament to motor test sample of ocean-sand mixing, bending strength shall be according to slag additament, but 40%~60% slag additament shall be quite obvious. Motor test sample of ocean-sand mixing shall be compared type Ⅰ cement with type Ⅱ cement, to make use of type Ⅱ cement to motor test sample of ocean-sand mixing shall have more compressive and bending strength about 10%, Rising of strength is best among non-standard sand mixing.

若添加炉石於海砂所拌和的水泥砂浆，其抗弯强度会随著炉石添加量的增加而增加，以40%~60%的炉石替代量为最佳；以第Ⅰ及第Ⅱ类型所拌和的海砂水泥砂浆试体做比较，依晚期强度而言，第Ⅱ类型水泥所拌和的试体，其抗压及抗弯强度比第Ⅰ类型水泥约高出10%左右，其中以非标准砂所拌和的试体强度上升最大。
